Despit occasional alarms, the country escaped any postwar depression and lived in a state of boom. A n economic survey of the year 1955, a typical ye ar of the 1950’s, may be typical as illustrating the rapid economic growth of the decade. The national output was value at 10 percent above that of 1954 (1955 output was estimated at 392 billion dollars). The production of manufacturers was about 40 percent more than it had averaged in the years immediately following World War 2. The country’s business spent about 30billion dollars for new factories and machinery. National income available for spending was almost a third greater than it had been it had been in 1950. Consumers spent about 256 billion dollars; that is about 700 million dollars a day ,or about twenty-five million dollars every hour , all round the clock. Sixty-five million people held jobs and only a little more than two million wanted jobs but could not find them . Only agriculture complained that it was not sharing in the room. To some observers this was an ominous echo of the mid-1920’s . As farmer’s shre of their products declined , marketing costs rose. But there were , among the observers of the national economy, a few who were not as confident as the majority . Those few seemed to fear that the boom could not last and would eventually lead to the oppsite-depression.1. What is the best title of the passage?a. The Agriculatural Trends of 1950’sb. The Unemployment Rate of 1950’sc. U.S. Economy in the 50’sd. The Federal Budget of 19522. In Line 4 , the word “boom”could best be replaced by______.a. nearby explosionb. thunderous noisec. general public supportd. rapid economic growth3. It can be inferred the national from the passage that most people in the United States in 1955 viewed the national economy with an air of _________.a. confidenceb. confusionc. disappointmentd. suspicion4. Which of the following were LEAST satisfied with the national economy in the 1950’s?a. Economistsb. Frmaersc. Politiciansd. Steelworkers5. The passage states that incom available for spending in the U.S. was greater in 1955 than in 1950 . How much was it ?a. 60%b. 50%c. 33%d. 90%答案：cdabc三Women are also underrepresented in the administration and this is because there are so few women full professors. In 1985,Regent Beryl Milburn produced a report blasting the University of Texas System adminitration for not encouraging women.The University was rated among the lowest for the system.In a 1987 update ,Milburn commended the progress that was made and called for even more improvement.One of the positive results from her study was a System-wide program to inform women of available administrative jobs.College of Communication Associate Dean Patrica Witherspoon,said it is important that woman be flexible when it comesto relocating if they want to rise in the ranks.Although a woman may face a chilly climate on campus , many times in order for her to succeed , she must rise above the problems around her and concentrate on her work.Until women make up a greater percentage of the senior positions in the University and all academia,inequities will exist."Women need to spend their energies and time doing scholarly activities that are important here at the University." Spirduso said. "If they do that will be successful in this system.If they spend their time in little groups mourning the sexual discrimination that they think exists here, they are wasting valuable study time."1.According to Spirduso,women need to ____.a.produce a report on sexual discriminationb.call for further improvement in their working conditionsc.spend their energies and time fighting against sexual discriminationd.spend more time and energy doing scholarly activities2.From this passage ,we know that _____.a.there are many women full professors in the University of Texasb.women play an important part in adminitrating the Universityc.the weather on the campus is chillyd.women make up a small percentage of the senior positions in the University3.Which of the following statements is true?a.the number of women professors in the University in 1987 was greater than that of 1985b.the number of women professors in the University in 1987 was smaller than that of 1985c.the number of women professors was the same as that of 1985d.more and more women professors thought that sexual discrimination did exit in the University4.One of the positive results from Milburn's study was that _____.a.women were told to con centrate on teir workb.women were given information about available administrative jobsc.women were encouraged to take on all the administrative jobs in the Unversityd.women were encouraged to do more scholarly activities5. The title for this passage should be _______.a.The University of Texasburn's Reportc.Women Professorsd.Sexual Discrimination in Academia答案：ddabd四Today ,as in every other day of the year ,more than 3000 U.S. adlescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime,it can be expected that of these 3000 about 23 will be murdered,30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweithts all other factors, whether voluntary or involuntary, as a cause of death.Since the late 1970s, when daily smoking among high school seniors reached 30 precent , smoking rates among youth have declined . While the decline is impressive ,several important issues must be raised.First, in the past several years,smoking rates among youth have declined very little. Second,in the late 1970s ,smoking among male high school seniors exceeded that among female by nearly 10 percent . The statistic is reversing.Third ,several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent .Finally, thouth significant declines in adolescent smoking have occurred in the past decade,no definite reasons for the decline exist. Within this context,the Naional Cancer Instiute (NCI) began its current effort to determine the most effecive measures to reduce smoking levesl among youth.1.According to the author, the deaths among youth are mainly caused by _____.a.traffic accidentsb.smoking-related deseasec.murderd.all of these2.Every day there are over_____high school strdents who will become regular smoker.a.75b.23c.30d.30003.By "dropout" the author means______.a.students who failed the examinationb.students who left schoolc.students who lost their wayd.students who were driven out of school4.The reason for declining adolescent smoking is that ________.a.NCI has taken effective measuresb.smoking is prevented among high school seniorsc.there are many smokers who have died of cancerd.none of these5.What is implied but not stated by the author is that ________.a.smoking rates among youth have declined very littleb.there are now more female than male smokers among high school seniorsc.high smoking rates are due to the incease in wealthd.smoking at high school are from low socio-economic backgrounds答案：bdbdb五The food we eat seems to have profound effects on our health.Although science has made enormous steps in making food more fit to eat ,it has, at the same time,made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additivies,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue.1.What is the best possible title of the passage?a.Drug and Foodb.Cancer and Healthc.Food and Healthd.Health and Drug2.Which of the following statements is NOT ture?a.Drugs are always given to animals for medical reasonsb.Some of the additives in our food are added to the food itself and some are given to the living animalsc.Researchers have known about the potential dangers of food additives for over thirty-five years.d.Food may cause forty percent of cancer in world.3.How has science done something harmful to mankind?a.Because of science , diseases caused by polluted food haven been virtually eliminated.b.It has caused a lack of information concerning the value of food.c.Because of the application of science,some potentially harmful substances have been added to food.d.The scientists have preserved the color of meats,but not of vegetables.4.What are nitrates used for?a.They preserve flavor in packaged foods.b.They preserve the color of meats.c.They are the objects of research.d.They cause the animals to become fatter.5.The word 'carcinogenic' most nearly means '_____'.a.trouble-makingb.color-retainingc.money-makingd.cancer-causing答案：cacbdWhat is your favourite colour? Do you like yellow , orange ,red? If you do ,you must be an optimist, a leader, an active person who enjoys life, people and excitement. Do you prefer greys and blues? Then you are probably quiet,shy, and you would rather follow than lead. You tend to be a pessimist. At least, this is what psychologists tell us, and they should know,because they have been seriously studying the meaning of colours preference, as well as the effect that colours have on human beings. They tells us, among other facts,that we do not choose our favourite clour as we grow up----we are born with our preference.If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.Colours do influence our moods----there is no doubt about it .A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand ,black is depressing. A black bridge over the Thames River, near London, used to be the scene of more suicides than any other bridge in the area ----until it was repainter green.The number of suicide attempts immediately fell sharply ;perhaps it would have fallen even more if the bridge had been done in pink or baby blue.Light and bright colours make people not only hppier but more active. It is an established fact that factory workers work better,harder ,and have fewer accidents when their machines are painted orange rather than black or grey.1."You would rather follow than red" means_______.a.you don't like to follow othersb.you would be a member rather than a leaderc.you would be afraid of following othersd.you would like to be a leader rather than a follower2.If one enjoys life, one is sure to prefer________.a.red to yellowb.blue to orangec.red to greyd.blue to yellow3."They tell us, among other facts,that we don't choose our favourite colours as we grow up." "Among other facts" means______.a.besides other factsb.in regard to other factsc.not considering other factsd.according to other facts4.Which of the following is facts?a.People's preference of one colour to another is instinctb.People's preference of one colour to another is acquired as they grow up.c.More people happen to love brown because they saw something brown when they were bornd.Colours have little influence on our moods5.Those who committed suicide preferred the bridge over the Thames River near london to others because of _______.a.its shapeb.its structurec.its colourd.its building materials答案：bcaac十二Social customs and ways of behaving change. Things which were considered impolite many years ago are now acceptable. Just a few years ago, it was considered impolite behaviour for a man to smoke on street. No man who thought of himself by smoking when a lady was in a room.Customs also differ from country to country. Does a man walk on the left or the right of a woman in your country? Or doesn't it matter? Should you use both hands when you are eating? Should leave one in your lap,or on the table?The Americans and the British not only speak the same language but also share a large number of social customs. For example, in both America and England people shake hands when they meet each other for the first time. Also, most Englishmen will open a door for a wonman or offer their seat to a woman , and so will most Americans. Promptness is important both in England and in America. That is , if a dinner invitation is for 7 o'clock , the dinner guest either arrives close to that time or calls up to explain his delay.The important thing to remember about social customs is not to do anything that might make other people feel uncomfortable-----especially if they are your guests. When the food was served , one of the guests strated to eat his peas with a knife . The other guests were amused or shocked , but the host calmly picked up his knife and began eating in the same way. It would have been bad manners to make his guest feel foolish or uncomfortable.1.If one has accepted a dinner invitation ,what should he do if he is tobe late for the dinner?a.He should find an excuseb.He should adk for excuse.c.He should say sorryd.He should telephone to explain his being late.2."It would have been bad manners to make his guests feel foolish or uncomfortable." "Bad manners " means ________.a.uglyb.dishonestc.impolited.shameful3.which of the following do you think is the best tiltle for this passage?a.Social Customs and Customsb.Social Lifec.American and British Customsd.Promptness Is Important4.According to the text, the best host_______.a.tries his best to make his guests feel comfortableb.makes his guests feel excitedc.tries to avoid being naughty to his guestsd.tries to avoid being foolish5.The author of this article may agree with which of the following?a.The guest who ate his peas with a knifeb.The other guests who were amused or shockedc.The host who picked up his knife and began eating in the same wayd.None of the above答案：dcaac十三New Orleans, Louisiana, was established as part of the French Empire in 1718.Its location on the east bank of the Mississippi River gave it control of the American hinerland and it became strategically important to many nations. It was transferred from France to Spain, returned to France,and finally sold by Napoleon to the United States in 1803. The city was the site of a famous battle fought in 1815 between the British, who hoped to control it , and the Americans under General And rew Jackson.The riverbed of the Mississippi is constantly silting and the river is now actually higher than the city. Levees hold back the river and giant pumps are used to move water from the city into the river.Although New Orleans haas beena part of the United States for almost two centuries, its population takes great pride in its French heritage. Louisiana still retains parts of the Code Napoleon which,form many years,was its only law.New Orleans is carefree city and it boasts its hot, spicy Creole seafood and its native Dixieland Jazz. The jackson Square neighborhood maintains its French colonial homes and in other sections are pre-Civil War mansions. Visitors are surprised to find that behind this interesting facade of yesteryear, is a busy industrial and port city. Grain and coal come from the Midwest and foreigh cargoes areunloaded here. New Orleans is no longer a sleepy Southern town----but it's still fun to visit.1.What accounts for the levees and pumps in New Orleans?a.The Mississippi frequently floods the city.b.The riverbed has raised inthe past 200 years.c.The torrential rains flood the city frequently.d.The high humidity cannot otherwise be comtrolled.2.The battle of New Orleans was fought by jackson against______.a.Franceb.Britainc.Spaind.The North3.The Code Napoleon was _______.a.an agreement to sell Louisianab.a body of lawsc.a city pland.a military code for the army4.Which of the following elements does not apply to the attiude of the inhabitants of New Orleans?a.Pride in their French heritage.b.A desire to retain picturesque colonial buildings.c.A refusal to engage in trade and commerced.A praising of Dixieland Jazz.5.Tourists visiting New Orleans are surprised to encounter_____.a.Creole foodb.Dixieland jazzc.bustling cityd.authentic colonial homes答案：bbbcc十四The United States is on the verge of losing its leading place in the world's technology. So says more than one study in recent years. One of the reasons for this decline is the parallel decline in the number of U.S. scientists and engineers.Since 1976,employment of scientists and engineers is up 85 percent. This trend is expected to continue. However, the trend shows that the number of 22-year-olds--the near term source of future PH.D.s-is declining. Further adding to the problem is the increased competition for these candidates from other fields-law,medicine,business,etc. While the number of U.S. PH.D.s in science and engineering declines,the award of PH.D.s to foreign nationals is increasing rapidly.Our inability to motivate students to pursue science and engineering careers at the graduate level is compounded because of the intense demand industry has for bright Bachelor's and Master's degree holders. Too often, promising PH.D.candidates, confronting the cost and financial sacrifice of pursuing their education,find the attraction of industry irresistible.1.The U.S.will come to lose its leading place in technology probably because ________.a. the number of PH.D. degree holders is decliningb. the number of scientists and engineers is decreasingc. the number of 22-year-ilds is decliningd. scientists and engineers are not employed2.The field of science and engineering is facing a competition from ________ .a. technologyb. foreign nationalsc. such fields as law, medicine and businessd. postgraduatesrge-scale enterprises now need _______.a. bright graduates and postgraduatesb. new inventionsc. advanced technologyd. engineers4.Many promising postgraduates are unwilling to pursue a PH.D. degree because _________.a. they are not encouraged to be engaged in scienceb. industry does not require PH.D. holdersc. they have financial difficultiesd. they will spend much time and energy completing PH.D.5.PH.D. candidates "find the attraction of industry irresistible" means that _________.a. they find industry is attracting more and more college studentsb. they don't think they can prevent themselves from working for industryc. they cannot resist any attraction from all sidesd. they cannot work for industry any longer答案：bcadb十五Newdays,a standard for measuring power has changed.These changes foretell a new standard for measuring power.No longer will a nation's political influence be based solely on the strength of its military forces. Of course, military effectiveness will remain a primary primary measure of power.But political influence is also closely tied to industrial competitiveness. It's often said that without its military the Soviet Union would really be a third-world nation. The new standard of opwer and influence that is evolving now places more emphasis on the ability of a country to compete effectively in the economic markets of the world.America must recognize this new course of events. Our success in shaping world events over the past 40 years has been the direct result of our ability to adapt technology and to take advantage of the capabilities of our people for the purpose of maintaining peace. Our industrial prowess over most of this period was unchallenged. It is ironic that it is just this prowess that has enabled other countries to prosper and in turn to threaten our industrial leadership.The competitiveness of America's industrial base is an issue bigger than the Department of Defense and is going to require the efforts of the major institutional forces in our society-government,industry,and education. That is not to say that the Defense Department will not be a strong force in the process because we will. But we simply cannot be, nor should we be, looked upon by others as the savior of American industry.1. Now a nation's political influence depends on _________.a. the strength of its military forcesb. its ability to compete in industryc. economic marketsd. both a and b2. The Soviet Union was not listed as a third-world nation just because of _________.a. its powerful military forcesb. its vast landc. its industrial competitivenessd. its contributions to world peace3. The author indicates that ______ is threatening American political power.a. other countriesb. the declining U.S. industrial basec. a new standard for measuring powerd. less advanced technology4. America succeeded in shaping world events over past 40 years probably because of ___________.a. its ability to adapt technologyb. its ability to take advantage of the capabilities of its peoplec. its ability to compete in the world marketsd. both a and b5. The purpose of writing this article is __________.a. to draw the readers' attention to a new standard for measuring powerb. to demonstrate American political influence in the worldc. to emphasize that efforts must be made to strengthen the declining U.S. industrial based. to show American industrial prowess答案：dabdc。

This is28due to a lack of necessary evidence.However,a new systematic review brings us usefully up-to-date on the current findings in this area.Before29into some of the key take-aways,an

to burn fat for energy.In contrast,anaerobic exercise—such as lifting heavy weights—is of such32intensity that your body does not have time to use oxygen to create energy and so instead it breaksdown

Much?A)How will we all keep busy when we only have to work15hours a week?That was the question that worriedthe British economist John Maynard Keynes when he wrote his short essay“Economic Possibilities for Our Grandchildren”in1930.Over the next century,he predicted,the economy would become so productive that people would barely need to work at all.For a while,it looked like Keynes was right.In1930the average working week was47hours in the United States.But by1970,the number of hours Americans worked on average had fallen to slightly less than39.B)But then something changed.Instead of continuing to decline,the duration of the working week remainedstable.It has stayed at just below40hours for nearly five decades.So what happened?Why are people working just as much today as in1970?C)There would be no mystery in this if Keynes had been wrong about the power of technology to increase theeconomy's productivity,which he thought would lead to a standard of living“between four and eight times as high as it is today.”But Keynes got that right:Technology has made the economy massively more productive.According to Benjamin M.Friedman,an economistat Harvard,the U.S.economy is right ontrack to reach Keynes's eight-fold(八倍)multiple by2029.That is a century after the last data Keynes wouldhave had access to.D)In a new paper,Friedman tries to figure out why that increased productivity has not translated into increasedleisure time.Perhaps people just never feel materially satisfied,always wanting more money to buy the next ·2024年6月四级真题(第一套)·4new thing.This is a theory that appeals to many economists.“This argument is,at best,far from sufficient,”he writes.If that were the case,why did the duration of the working week decline in the first place?E)Another theory Friedman considers is that,in an era of ever fewer settings that provide effectiveopportunitiesfor personal connections and relationships,people may place more value on the socializing that happens at work.There is support for this theory.Many people today consider colleagues as friends.But Friedman argues that the evidence for this theory is far from conclusive.Many workers report that they would like to spend more time with family,rather than at work.Furthermore,this theory cannot explain the change in trend in the U.S.working week in the1970s.F)A third possibility proves more convincing for Friedman.That is:American inequality means that the gainsof increasing productivity are not widely shared by everyone.In other words,most Americans are too poor to work less.Unlike the other two explanations Friedman considers,this one fits chronologically(按年代).Inequality declined in America during the period following World War II,along with the duration of the working week.But since the early1970s it has risen dramatically.G)Keynes's prediction of a shorter working week rests on the idea that the standard of living would continuerising for everyone.But Friedman says that this is not what has happened.Although Keynes's eight-fold figure holds up for the economy as a whole,it is not at all the case for the median(中位数的)American worker.For them,output by2029is likely to be around3.5times what it was when Keynes was writing.This is a bit below his four-to eight-fold predicted rangeH)This can be seen in the median worker's income over this time period,complete with a shift in1973that fitsin precisely with when the working week stopped shrinking.According to Friedman,between1947and1973 the average hourly wage for normal workers(those who were not in management roles)in private industries other than agriculture nearly doubled in terms of what their money could buy.But by2013the average hourly wage for ordinary workers had fallen5percent from the1973level in terms of actual purchasing power.Thus,though American incomes may have gone up since1973,the amount that American workers can actually buy with their money has gone down.For most Americans,then,the magic of increasing productivity stopped working around1973.Thus,they had to keep working just as much in order to maintain their standard of livingI)What Keynes predicted was a very optimistic version of what economists call technological unemployment.This is the idea that less labor will be necessary because machines can do somuch.In Keynes's vision,the resulting unemployment would be distributed more or less evenly across society in the form of increased leisure.But Friedman says that,for Americans,reality is much darker.Americans now have a labor market in which millions of people—those with fewer skills and less education—are seeking whatever poorly paid work they can get.This is confirmed by a recent poll that found that,for half of hourly workers,their top concern is not that they work too much but that they work too little.This is most likely not because they like their jobs so much.Rather,we can assume it is because they need the money.J)This explanation leaves an important question.If the very rich—the workers who have reaped above-average gains from the increased productivity since Keynes's time—can afford to work less,why do they continue to work so much?(Indeed,research has shown that the highest earners in America tend to work the most.)5·2024年6月四级真题(第一套)·Friedman believes that for many top earners,work is a labor of love.They are doing work they care about and are interested in,and doing more of it is not necessarily a burden.For them,it may even be a pleasure.These top earners derive meaning from their jobs and work is an important part of how they think of themselves.And,of course,they are compensated for it at a level that makes it worth their while.K)Friedman concludes that the prosperity(繁荣)Keynes predicted is here.After all,the economy as a whole has grown even more brilliantly than he expected.But for most Americans,that prosperity is nowhere to be seen.And,as a result,neither are those shorter working weeks.36.Some people view socializing at the workplace as a chance to develop personal relationships.37.As ordinary American workers'average hourly pay had decreased despite increasing productivity,they had towork just as manyhours as before to keep their living standards.38.American workers'average weekly workingtime has not changed for nearly half a century.39.Friedman believes inequality in the rgely explains why increasing productivity has not resulted inreduced working hours.40.Many economists assume people's thirst for material things has prevented them from enjoying more leisuretime.41.An economist'sprediction about a shorter average working week seemed to be correct for a time in the20thcentury.42.In the bor market,the primary concern of people with less schooling and fewer skills is to secure anyemployment even if it is low-paid.43.Keynes was right in predicting that technology would make the economy much more productive.44.Many of the highest earners have a keen interest in and love for what they are doing45.According to Keynes,there would be a shorter working week with everyone's standard of living continuingtorise.Section CDirections:There are2passages in this section.Eachpassage is followed by some questions or unfinished statements.For each of them there are four choices marked A),B),C)and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet2with a single line through the centre.Passage OneQuestions46to50are based on the following passage.Lao Zi once said,“Care about what other people think and you will always be their prisoner.”People-pleasing,or seeking self-worth through others'approval,is unproductive and an exhausting way to go through life.Why do we allow what others think of us to have so much power over how we feel about ourselves?If it's true that you can't please all people all of the time,wouldn't it make sense to stop trying?Unfortunately,sense often isn't driving our behavior.For social beings who desire love and belonging, wanting to be liked,and caring about the effect we have on others,is healthy and allows us to make connections.·2024年6月四级真题(第一套)·6However,where we get into trouble is when our self-worth is dependent upon whether we win someone's approval or not.This need to be liked can be traced back to when we were children and werecompletely dependent on others to take care of us:Small children are not just learning how to walk and communicate,they are alsotrying to learn how the world works.We learn about who we are and what is expected of us based on interactions with others so,to a four-year-old,if Mommy or Daddy doesn't like him or her,there is the danger that they will abandon them.We need to understand that when we desperately want someone to approveof us,it's being driven by that little kid part of us that is still terrified of abandonment.As you become more capable of providing yourself with the approval you seek,your need for external validation will start to vanish,leaving you stronger,more confident,and yes,happier in your life.Imagine how much time we lose each moment we restrainour authentic selves in an effort to be liked.If we base our worth on the opinions of others,we cheat ourselves of the power to shape our experiences and embrace life not only for others but also for ourselves,becauseultimately,there is no difference.So embrace the cliché(老话)and loveyourself as it's highly doubtful that you'll regret it.46.What can we conclude from Lao Zi's quotation?A)We should seethrough otherpeople's attempt to make a prisonerof us.B)We can never really please other people even if we try as hard as we can.C)We can never be truly free if taking to heart others'opinion of us.D)We should care about other people's view as much as they care about our own.47.What will happen if we base our self-worth on other people's approval?A)Our desire to be loved will be fulfilled.C)Our identity as social beings will be affected.B)Our life will be unfruitful and exhausting D)Our sense of self will be sharpened and enhanced.48.What may account for our need to be liked or approved of?A)Our desperate longing for interactions with others.C)Our knowledge about the pain of abandonment.B)Our understanding of the workings of the world.D)Our early childhood fear of being deserted.49.What can we do when we become better able to provide ourselves with the desired approval?A)Enjoy a happier life.C)Receive more external validation.B)Exercise self-restraint.D)Strengthen our power of imagination.50.What does the author advise us to do in the last paragraph?A)Embrace life for ourselves and for others.C)See our experiencesas assets.B)Base our worth on others'opinions.D)Love ourselves as we arePassage TwoQuestions51to55are based on the following passage.Some people have said aging is more a slide into forgetfulness than a journey towards wisdom.However,a growing body of research suggests that late-in-life learning is possible.In reality,education does an aging brain good.7·2024年6月四级真题(第一套)·Throughout life,people's brains constantly renovate themselves.In the late1960s,British brain scientist Geoffrey Raisman spied growth in damaged brain regions ofrats through an electron microscope; their brains were forging new connections.This meant brains may change every time a person learns something new.Of course,that doesn't mean the brain isn't affected by the effects of time.Just as height usually declines over the years,so does brain volume:Humans lose about4percent every decade starting in their40s.But that reduction doesn't necessarily make people think slower;as long as we are alive and functioning,we can alter our brains with new information and experiences.In fact,scientists now suspect accumulating novel experiences,facts,and skills can keep people's minds more flexible.New pathways can strengthen our ever-changing mental structure,even as the brain shrinks.Conventional fixes like word puzzles and brain-training apps can contribute to mental durability.Even something as simple as taking a different route to the grocery store or going somewhere new on vacation can keep the brain healthy.A desire for new life challenges can further boost brainpower.Research about aging adults who take on new enterprises shows improved function and memory as well as a reduced risk of mental disease.Openness—a characteristic defined by curiosity and a desire for knowledge—may also help folks pass brain tests.Some folks are born with this take-in-the-world atitude,but those who aren't as genetically gifted aren't necessarily out of luck.While genes can encourage an interest in doing new things,a2012study in the journal Psychology and Aging found completing reasoning tasks like puzzles and number games can enhance that desire for novel experiences,which can,in turn,refresh the brain.That's why brain scientist Richard Kennedy says“It's not that old dogs can't learn new tricks.It's that maybe old dogs don't realize why they should.”51.What do some people think of aging adults?A)Their wisdom grows as time goes by.C)They can benefit from late-in-life learning.B)Their memory gradually deteriorates D)They are likely to have mental health issues.52.What can we conclude from Geoffrey Raisman's finding?A)Brain damage seriously hinders one'slearning.C)Brains can refresh and improve with learning.B)Brain power weakens slower than we imagine D)Brains forge connections under new conditions53.What is one thing that helps maintain the health of our brain even as it shrinks?A)Doing daily routines by conventional means.C)Imitating old dogs'way of learning new tricksB)Avoiding worrying about our mental durability.D)Approaching everyday tasks in novel ways.54.What does the author say can contribute to the improvement of brain function?A)Being curious and desiring knowledge.C)Rising to life's challenges and avoiding risks.B)Being eager to pass brain tests at an old age.D)Boosting immunity to serious mental diseases55.What is the finding of the2012study in the journal Psychology and Aging?A)Wishing to solve puzzles enhances one's reasoning power.B)Playingnumber games unexpectedly stimulates one's memory.·2024年6月四级真题(第一套)·8C)Desiring new experiences can help to renovate thebrain.D)Learning new tricks

2022年6月大学英语四级真题及答案(第一套)一、四级作文部分：WritingDirections: Suppose you are writing a proposal to your school library about improving it' s services, you are writing about its current problems and solutions.Dear Sir or Madam,I hope you are doing great! I am Li Ming, one of the sophomore students in our university. Following my recent experience of using our school library, I have decided to send you some feed-back. In the first place, the librarians there are not very friend-ly and helpful as they often fail to tell us where to find the book we want, and moreover get impatient easily. What’s more, the books available in the library are too old to catch up with the latest development of related disciplines. Finally, the reading rooms are not bright enough as some of the lights have gone dark. All these have brought great inconvenience to us students, which leaves me with no choice but to write you this letter.From my perspective, it would be wise for you to offer all the librarians a training course to familiarize them with the layout of the library and the classifications of the books. If possible, I sincerely hope that you consider the possibility of renewing some of the books and maintaining the facilities properly.Thank you for your time and consideration. Look forward to your favorable reply.Warm regards,Li Ming二、四级听力部分：四级听力原文：Section ANews Report 1原文：[1] A new study finds that beverages containing add ed sugar might be harmfuL In the study, researchers a nalyzed information from over eighty thousand wome n and thirty seven thousand men.

You can start your essay with the sentence "O nline dictionaries arebecoming increasingly popular. " You should write at least 120 words but no more than 180 words.参考范文：With the growing popularity of smart phones and the high coverage rate of wireless network, online dictionaries are becoming increasingly popular for students in daily study. It seems to be a trend that online dictionaries would replace paper ones. However, just as the saying goes, “different strokes for different folks.”Some students are more prone to use online dictionaries and have two points to support it. First, online dictionaries are more portable, and make it possible to look up any new words that we met anytime and anywhere only via a small phone in our hands. Second, we can improve both written and oral skills, as online dictionaries allow us to hear the native pronunciation of each word clearly. Whereas others hold differently. They are still in favor of use print ones. For one thing, paper dictionaries can protect our eyesight better than online ones as digital devices may emit radiation if we watch the electronic screen for a long time. For another, using the print dictionary can prevent us from being distracted by reminders of irrelevant information.As far as I’m concerned, although the content of paper dictionaries is authoritative, its lexicon is not updated as quickly as online ones. After all, we live in an informationage and can have access to many hot words on the Internet every day.【选词填空第1套】26. H integrate27. B coincidence28. A associated29. L recognizable30. I maximizes31.

"You should write at least 120 words but no more than 180 words.参考范文：With the growing popularity of smart phones and the high coverage rate of wireless network, online dictionaries are becoming increasingly popular for students in daily study. It seems to be a trend that online dictionaries would replace paper ones. However, just as the saying goes, “different strokes for different folks.”Some students are more prone to use online dictionaries and have two points to support it. First, online dictionaries are more portable, and make it possible to look up any new words that we met anytime and anywhere only via a small phone in our hands. Second, we can improve both written and oral skills, as online dictionaries allow us to hear the native pronunciation of each word clearly. Whereas others hold differently. They are still in favor of use print ones. For one thing, paper dictionaries can protect our eyesight better than online ones as digital devices may emit radiation if we watch the electronic screen for a long time. For another, using the print dictionary can prevent us from being distracted by reminders of irrelevant information.As far as I’m concerned, although the content of paper dictionaries is authoritative, its lexicon is not updated as quickly as online ones. After all, we live in an informationage and can have access to many hot words on the Internet every day.【选词填空第1套】26. H integrate27. B coincidence28. A associated29. L recognizable30. I maximizes31.

As the pace of life continues to increase ,we are fast losing the art of relaxation. Once you are in the habit of rushing through lift,being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.Stress is an natural part of everyday lift and there is no way to avoid it. In fact ,it is not the bad thing it is often supposed to be .A certain amount of stress is vital to provide motivation adn give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress,and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress,in whatever form,we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme,but however little the stress,it involves the same response. It is when such a reaction lasts long,through continued exposure to stress,that health becomes endangered.Such serious conditions as high blood pressure and heart disease have established links with stress.Since we cannot remove stress from our lives(it would be unwise to do so even if we could),we need to find ways to deal with it.1.People are finding less and less time for relaxing themselves because_____.a.they do not know how to enjoy themselvesb.they do not believe that relaxation is important for healthc.they are travelling fast all the timed.they are becoming busier with their work2.According to the writer ,the most important character for a good manager is his ________.a.not fearing stressb.knowing the art of relaxationc.high sense of responsibilityd.having control over performance3.Which of the follwing statements is ture?a.We can find some ways to avoid stressb.Stress is always harmful to peoplec.It is easy to change the hagit of keeping oneself busy with work.d.Different people can withstand different amounts of stress4.In Paragraph 3, "such a reaction" refers back to_______.a."making a choice between 'flight' or 'fight'"b."reaction to stress both chemically and physically"c."responding to crises quickly"d."losing heart at the signs difficulties"5.In the last sentence of the passage,"do so " refers to ______.a."expose ourselves to stress"b."find ways to deal with stress"c."remove stress from our lives"d."established links between diseases and stress"答案：dadbcIn the 1960s, many young Americans were dissatisfied with American society. They wanted to end the Vietnam War and to make all of the people in the U.S. epual. Some of them decided to "drop out" of American society and form their own societies . They formed utopian communities , which they called "communes," where they could follow their philosophy of "do your own thing." A group of artists founded a commune in southern Colorado called "Drop City." Following the ideas of philosopher and architect Buckminster Fuller they built domeshaped houses from pieces of old cars. Other groups, such as author Ken Kesey's Merry Pranksters, the followers fo San Francisco poet Steve Gakin, and a group that called itself the Hog Farm, lived in old school huses and traveled around the United States. The Hog Farm become famous when they helped organize the Woodstock Rock Festival in 1969. Steve Gaskin's followers tried to settle down on a farm in Tennessee, but they had to leave when some members of the gruop were arrested for growing marijuana.Not all communes believed in the philosophy of "do you own thing," however . Twin Oaks , a commune founded in Virgiania in the late 1960s, was based on the ideas of psychologist B.F.Skinner. The people who lived at Twin Oaks were carefully controlled by Skinner's "conditioning" techniques to do things that were good for the community. In 1972, Italian architect Paolo Soleri began to build Arcosanti, a utopian city Arizsona where 2500 people will live closely together in one large building called an "archology" Soleri believes that people must live closely together so that they will all become one.1.Why did some young Americans decide to "drop out" of scoiety during the 1960s?a.They were not satisfied with American society.b.They wanted to grow marijuana.c.They wanted to go to the Vietnam War.d.They did not want all people to be equal.2.Where did the members of the Hog Farm commune live?a.In dome-shaped houseb.In old school husesc.On a farm inTennesseed.In an archology in Arizona3.Who gave the people of Drop City the idea to bulid dome-shaped house?a.Paolo Solerib.B.G.Skinnerc.Steve Gaskind.Buckminster Fuller4.What was the Twin Oaks commune base on ?a.The philosophy of "do your own thing"b.Virginaia in the late 1960sc.The ideas of psychologistd.The belief that people must live closely togerher.5.What is an "archology"?a.A person who studies archaeologyb.A large building where people live closely togetherc.A city in A rizonad.A technique to contorl people答案：abdcbThere are two factors which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual—the sort of environment in which he is reared. If an individual is handicapped envionmentally ,it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.The importance of environment in determining an individual's intellingence can be demonstrated by the case history of the identical twins, Peter and Mark X. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old , their parents died, and they were placed in separate foster homes. Peter was reated by parents of low intelligence in an isolatedcommunity with poor educational pooprtunities.Mark was reared inthe home of well-to-do parents who had been to college. He was read to as a child , sent to good schools, and given every opportunity to be stimulated intellectually.This enviromental difference continued until the twins were in their late teens, when they were giben tesets to measure their intelligence. Mark's I.Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities , the twins , having identical brains,would have tested at roughly the same level.1.This selection can best be titled_________.a.Measuring Your Intelligenceb.Intelligence and Environmentc.The Case of Peter and Markd.How the brain Influences Intelligence2.The beststatement of the main idea of this passage is that _____.a.human brains differ considerablyb.the brain a person is born with is improtant in determining his intelligencec.environment is crucial in determining a person's intelligenced. persons having identical brains will have roughly the same intelligence3.According to the passage , the average I.Q.is _____.a.85b.100c.110d.1254.The case history of the twins appears to support the conclusion that _______.a.individual with identical brains seldom test at same levelb.an individual's intelligence is determined only by his enviromentck of opportunity blocks the growth of intelligenced.changes of enviroment produce changes in the structure of the brain5.This passage suggests that an individual 's I.Q.______.a.can be predicted at birthb.stays the same throuthout his lifec.can be increased by educationd.is determined by his childhood答案：bcbccAs she walked round the huge department store,Edith reflected how difficult it was to choose a suitable Christmas present for her father.She wish that he was as easy to please as her mother, who was always delighted with perfumeBesides,shoppong at this time of the year was a most disgreeable experience :people trod on yourtoes,poked you with their elbows and almost knocked you overin their haste to get to a bargain ahead of you.Partly to have a rest, Edith paused in front of a counter where some attracive ties were on display. "They are real silk," the assistant assured her, trying to tempt her. "Worth double the price." But edit knew from past experience that her choice of ties hardly ever pleased her father.She moved on reluctantly and then quite by chance, stopped where a small crowd of man had gathered round a counter. She found some good quality pipes on sale-----and the prices were very reasonable. Edith didnot hesitate for long : although her father only smoked a pipe occasionally, she knew that this was a present which was bund to please him.When she got home,with her small well-chosen present concealed in her handbag, her parents were already at the supper table. Her mother was in an especially cheerful mood, "Your father has at last to decided to stop smoking." She informed her daughter.1.Edith's father _______.a.did not like presentb.never got presentc.preferred tiesd.was difficult to choose a present for2.The assistant spoke to Edith because she seemed_______.a.attractiveb.interested in tiesc.tiredd.in need of comfort3.Edith stopped at the next counter_________.a.puroselyb.suddenlyc.unwillinglyd.accidentally4.Edith's father smoked a pipe_______.a.when he was obligedb.on social occasionsc.from time to timed.when he was delighted5.Shopping was very disagreeable at that time of the year because_______.a.coustomers trod on each other's toesb.coustomers poked each other with their elbowsc.customers knocked each otherd.customers were doing their shopping in a great hurry答案：dbdcdIf the population of the earth goes on increasing at its present rate, there will eventually not be enough resources left to sustain life on the planet.By the middle of the 21st century,if present trends continue, we will have used up all the oil that drives our cars,for example.Even if scientists develop new ways of feeding the human race,the crowded conditions on earth will make it necessary for lus to look for open space somewhere else. But none of the other planets in our solar system are capable of supporting life at present. One possible solution to the problem, however,has recently been suggested by American scientist, Professor Carl Sagan.Sagan believes that before the earth's resources are compleetely exhausted it will be possible to change the atmophere of Venus and so create a new world almost as large as earth itself. The difficult is that Venus is much hotter than the earth and there is only a tiny amount of water there.Sagan proposes that algae organisms that can live in extremely hot or cold atmospheres and at the same time produce oxygen,should be bred in condition similar to those on Venus.As soon as this has been done, the algae will be placed in small rockets. Spaceship will then fly to Venus and fire the rockets into the atmosphere .In a fairly short time, the alge will break down the carbon dioxide into oxygen and carbon.When the algae have done theri work, the atmosphere will become cooler,but befor man can set foot on Venus it will be neccessary for the oxygen to produce rain. The surface of the planet will still be too hot for man to land on it but the rain will eventually fall and in a few years something like earth will be reproduced on Venus.1.Inte long run, the most insoluble problem caused by population growth on earth will probably be the lack of ______.a.foodb.oilc.spaced.resources2.Carl Sagan believes that Venus might be colonized from earth because _____a.it might be possible to change its atmosphereb.its atmosphere is the same as the earth'sc.there is a good supply of water on Venusd.the days on Venus are long enough3.On Venus there is a lot of ________.a.waterb.carbon dioxidec.carbon monoxided.oxygen4.Algae are plants that can____.a.live in very hot temperaturesb.live in very cold temperaturesc.manufacture oxygend.all of the above5. Man can land on Venus only when_______.a.the algae have done their workb.the atmosphere becomes coolerc.thereis oxygend.it rains there答案：cabdd。
大学英语四级阅读理解试题及答案

Despit occasional alarms, the country escaped any postwar depression and lived in a state of boom. A n economic survey of the year 1955, a typical year of the 1950’s, may be typical as illustrating the rapid economic growth of the decade. The national output was value at 10 percent above that of 1954 (1955 output was estimated at 392 billion dollars). The production of manufacturers was about 40 percent more than it had averaged in the years immediately following World War 2. The country’s business spent about 30billion dollars for new factories and machinery. National income available for spending was almost a third greater than it had been it had been in 1950. Consumers spent about 256 billion dollars; that is about 700 million dollars a day ,or about twenty-five million dollars every hour , all round the clock. Sixty-five million people held jobs and only a little more than two million wanted jobs but could not find them . Only agriculture complained that it was not sharing in the room. To some observers this was an ominous echo of the mid-1920’s . As farmer’s shre of their products declined , marketing costs rose. But there were , among the observers of the national economy, a few who were not as confident as the majority . Those few seemed to fear that the boom could not last and would eventually lead to the oppsite-depression.1. What is the best title of the passage?a. The Agriculatural Trends of 1950’sb. The Unemployment Rate of 1950’sc. U.S. Economy in the 50’sd. The Federal Budget of 19522. In Line 4 , the word “boom”could best be replaced by______.a. nearby explosionb. thunderous noisec. general public supportd. rapid economic growth3.

The passage states that incom available for spending in the U.S. was greater in 1955 than in 1950 . How much was it ?a. 60%b. 50%c. 33%d. 90%答案：cdabc三Women are also underrepresented in the administration and this is because there are so few women full professors. In 1985,Regent Beryl Milburn produced a report blasting the University of Texas System adminitration for not encouraging women.The University was rated among the lowest for the system.In a 1987 update ,Milburn commended the progress that was made and called for even more improvement.One of the positive results from her study was a System-wide program to inform women of available administrative jobs.College of Communication Associate Dean Patrica Witherspoon,said it is important that woman be flexible when it comesto relocating if they want to rise in the ranks.Although a woman may face a chilly climate on campus , many times in order for her to succeed , she must rise above the problems around her and concentrate on her work.Until women make up a greater percentage of the senior positions in the University and all academia,inequities will exist."Women need to spend their energies and time doing scholarly activities that are important here at the University." Spirduso said. "If they do that will be successful in this system.If they spend their time in little groups mourning the sexual discrimination that they think exists here, they are wasting valuable study time."1.According to Spirduso,women need to ____.a.produce a report on sexual discriminationb.call for further improvement in their working conditionsc.spend their energies and time fighting against sexual discriminationd.spend more time and energy doing scholarly activities2.From this passage ,we know that _____.a.there are many women full professors in the University of Texasb.women play an important part in adminitrating the Universityc.the weather on the campus is chillyd.women make up a small percentage of the senior positions in the University3.Which of the following statements is true?a.the number of women professors in the University in 1987 was greater than that of 1985b.the number of women professors in the University in 1987 was smaller than that of 1985c.the number of women professors was the same as that of 1985d.more and more women professors thought that sexual discrimination did exit in the University4.One of the positive results from Milburn's study was that _____.a.women were told to con centrate on teir workb.women were given information about available administrative jobsc.women were encouraged to take on all the administrative jobs in the Unversityd.women were encouraged to do more scholarly activities5. The title for this passage should be _______.a.The University of Texasburn's Reportc.Women Professorsd.Sexual Discrimination in Academia答案：ddabd四Today ,as in every other day of the year ,more than 3000 U.S. adlescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime,it can be expected that of these 3000 about 23 will be murdered,30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweithts all other factors, whether voluntary or involuntary, as a cause of death.Since the late 1970s, when daily smoking among high school seniors reached 30 precent , smoking rates among youth have declined . While the decline is impressive ,several important issues must be raised.First, in the past several years,smoking rates among youth have declined very little. Second,in the late 1970s ,smoking among male high school seniors exceeded that among female by nearly 10 percent . The statistic is reversing.Third ,several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent .Finally, thouth significant declines in adolescent smoking have occurred in the past decade,no definite reasons for the decline exist. Within this context,the Naional Cancer Instiute (NCI) began its current effort to determine the most effecive measures to reduce smoking levesl among youth.1.According to the author, the deaths among youth are mainly caused by _____.a.traffic accidentsb.smoking-related deseasec.murderd.all of these2.Every day there are over_____high school strdents who will become regular smoker.a.75b.23c.30d.30003.By "dropout" the author means______.a.students who failed the examinationb.students who left schoolc.students who lost their wayd.students who were driven out of school4.The reason for declining adolescent smoking is that ________.a.NCI has taken effective measuresb.smoking is prevented among high school seniorsc.there are many smokers who have died of cancerd.none of these5.What is implied but not stated by the author is that ________.a.smoking rates among youth have declined very littleb.there are now more female than male smokers among high school seniorsc.high smoking rates are due to the incease in wealthd.smoking at high school are from low socio-economic backgrounds答案：bdbdb五The food we eat seems to have profound effects on our health.Although science has made enormous steps in making food more fit to eat ,it has, at the same time,made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additivies,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue.1.What is the best possible title of the passage?a.Drug and Foodb.Cancer and Healthc.Food and Healthd.Health and Drug2.Which of the following statements is NOT ture?a.Drugs are always given to animals for medical reasonsb.Some of the additives in our food are added to the food itself and some are given to the living animalsc.Researchers have known about the potential dangers of food additives for over thirty-five years.d.Food may cause forty percent of cancer in world.3.How has science done something harmful to mankind?a.Because of science , diseases caused by polluted food haven been virtually eliminated.b.It has caused a lack of information concerning the value of food.c.Because of the application of science,some potentially harmful substances have been added to food.d.The scientists have preserved the color of meats,but not of vegetables.4.What are nitrates used for?a.They preserve flavor in packaged foods.b.They preserve the color of meats.c.They are the objects of research.d.They cause the animals to become fatter.5.The word 'carcinogenic' most nearly means '_____'.a.trouble-makingb.color-retainingc.money-makingd.cancer-causing答案：cacbd六As the pace of life continues to increase ,we are fast losing the art of relaxation. Once you are in the habit of rushing through lift,being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.Stress is an natural part of everyday lift and there is no way to avoid it. In fact ,it is not the bad thing it is often supposed to be .A certain amount of stress is vital to provide motivation adn give purpose to life.

They wanted to end the Vietnam War and to make all of the people in the U.S. epual. Some of them decided to "drop out" of American society and form their own societies . They formed utopian communities , which they called "communes," where they could follow their philosophy of "do your own thing."A group of artists founded a commune in southern Colorado called "Drop City." Following the ideas of philosopher and architect Buckminster Fuller they built domeshaped houses from pieces of old cars. Other groups, such as author Ken Kesey's Merry Pranksters, the followers fo San Francisco poet Steve Gakin, and a group that called itself the Hog Farm, lived in old school huses and traveled around the United States. The Hog Farm become famous when they helped organize the Woodstock Rock Festival in 1969. Steve Gaskin's followers tried to settle down on a farm in Tennessee, but they had to leave when some members of the gruop were arrested for growing marijuana.Not all communes believed in the philosophy of "do you own thing," however . Twin Oaks , a commune founded in Virgiania in the late 1960s, was based on the ideas of psychologist B.F.Skinner. The people who lived at Twin Oaks were carefully controlled by Skinner's "conditioning" techniques to do things that were good for the community. In 1972, Italian architect Paolo Soleri began to build Arcosanti, a utopian city Arizsona where 2500 people will live closely together in one large building called an "archology" Soleri believes that people must live closely together so that they will all become one.1.Why did some young Americans decide to "drop out" of scoiety during the 1960s?a.They were not satisfied with American society.b.They wanted to grow marijuana.c.They wanted to go to the Vietnam War.d.They did not want all people to be equal.2.Where did the members of the Hog Farm commune live?a.In dome-shaped houseb.In old school husesc.On a farm inTennesseed.In an archology in Arizona3.Who gave the people of Drop City the idea to bulid dome-shaped house?a.Paolo Solerib.B.G.Skinnerc.Steve Gaskind.Buckminster Fuller4.What was the Twin Oaks commune base on ?a.The philosophy of "do your own thing"b.Virginaia in the late 1960sc.The ideas of psychologistd.The belief that people must live closely togerher.5.What is an "archology"?a.A person who studies archaeologyb.A large building where people live closely togetherc.A city in A rizonad.A technique to contorl people答案：abdcb八There are two factors which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual—the sort of environment in which he is reared. If an individual is handicapped envionmentally ,it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.The importance of environment in determining an individual's intellingence can be demonstrated by the case history of the identical twins, Peter and Mark X. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old , their parents died, and they were placed in separate foster homes. Peter was reated by parents of low intelligence in an isolatedcommunity with poor educational pooprtunities.Mark was reared inthe home of well-to-do parents who had been to college. He was read to as a child , sent to good schools, and given every opportunity to be stimulated intellectually.This enviromental difference continued until the twins were in their late teens, when they were giben tesets to measure their intelligence. Mark's I.Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities , the twins , having identical brains,would have tested at roughly the same level.1.This selection can best be titled_________.a.Measuring Your Intelligenceb.Intelligence and Environmentc.The Case of Peter and Markd.How the brain Influences Intelligence2.The beststatement of the main idea of this passage is that _____.a.human brains differ considerablyb.the brain a person is born with is improtant in determining his intelligencec.environment is crucial in determining a person's intelligenced. persons having identical brains will have roughly the same intelligence3.According to the passage , the average I.Q.is _____.a.85b.100c.110d.1254.The case history of the twins appears to support the conclusion that _______.a.individual with identical brains seldom test at same levelb.an individual's intelligence is determined only by his enviromentck of opportunity blocks the growth of intelligenced.changes of enviroment produce changes in the structure of the brain5.This passage suggests that an individual 's I.Q.______.a.can be predicted at birthb.stays the same throuthout his lifec.can be increased by educationd.is determined by his childhood答案：bcbcc九As she walked round the huge department store,Edith reflected how difficult it was to choose a suitable Christmas present for her father.She wish that he was as easy to please as her mother, who was always delighted with perfumeBesides,shoppong at this time of the year was a most disgreeable experience :people trod on your toes,poked you with their elbows and almost knocked you overin their haste to get to a bargain ahead of you.Partly to have a rest, Edith paused in front of a counter where some attracive ties were on display. "They are real silk," the assistant assured her, trying to tempt her. "Worth double the price." But edit knew from past experience that her choice of ties hardly ever pleased her father.She moved on reluctantly and then quite by chance, stopped where a small crowd of man had gathered round a counter. She found some good quality pipes on sale-----and the prices were very reasonable. Edith did not hesitate for long : although her father only smoked a pipe occasionally, she knew that this was a present which was bund to please him.When she got home,with her small well-chosen present concealed in her handbag, her parents were already at the supper table. Her mother was in an especially cheerful mood, "Your father has at last to decided to stop smoking." She informed her daughter.1.Edith's father _______.a.did not like presentb.never got presentc.preferred tiesd.was difficult to choose a present for2.The assistant spoke to Edith because she seemed_______.a.attractiveb.interested in tiesc.tiredd.in need of comfort3.Edith stopped at the next counter_________.a.puroselyb.suddenlyc.unwillinglyd.accidentally4.Edith's father smoked a pipe_______.a.when he was obligedb.on social occasionsc.from time to timed.when he was delighted5.Shopping was very disagreeable at that time of the year because_______.a.coustomers trod on each other's toesb.coustomers poked each other with their elbowsc.customers knocked each otherd.customers were doing their shopping in a great hurry答案：dbdcd十If the population of the earth goes on increasing at its present rate, there will eventually not be enough resources left to sustain life on the planet.By the middle of the 21st century,if present trends continue, we will have used up all the oil that drives our cars,for example.Even if scientists develop new ways of feeding the human race,the crowded conditions on earth will make it necessary for lus to look for open space somewhere else. But none of the other planets in our solar system are capable of supporting life at present. One possible solution to the problem, however,has recently been suggested by American scientist, Professor Carl Sagan.Sagan believes that before the earth's resources are compleetely exhausted it will be possible to change the atmophere of Venus and so create a new world almost as large as earth itself. The difficult is that Venus is much hotter than the earth and there is only a tiny amount of water there.Sagan proposes that algae organisms that can live in extremely hot or cold atmospheres and at the same time produce oxygen,should be bred in condition similar to those on Venus.As soon as this has been done, the algae will be placed in small rockets. Spaceship will then fly to Venus and fire the rockets into the atmosphere .In a fairly short time, the alge will break down the carbon dioxide into oxygen and carbon.When the algae have done theri work, the atmosphere will become cooler,but befor man can set foot on Venus it will be neccessary for the oxygen to produce rain. The surface of the planet will still be too hot for man to land on it but the rain will eventually fall and in a few years something like earth will be reproduced on Venus.1.Inte long run, the most insoluble problem caused by population growth on earth will probably be the lack of ______.a.foodb.oilc.spaced.resources2.Carl Sagan believes that Venus might be colonized from earth because _____a.it might be possible to change its atmosphereb.its atmosphere is the same as the earth'sc.there is a good supply of water on Venusd.the days on Venus are long enough3.On Venus there is a lot of ________.a.waterb.carbon dioxidec.carbon monoxided.oxygen4.Algae are plants that can____.a.live in very hot temperaturesb.live in very cold temperaturesc.manufacture oxygend.all of the above5. Man can land on Venus only when_______.a.the algae have done their workb.the atmosphere becomes coolerc.thereis oxygend.it rains there答案：cabdd阅读理解限时训练与解析A（5minutes）I found out one time that doing a favor for someone could get you into a lot of trouble. I was in the eighth grade at the time, and we were having a final test. During the test, the girl sitting next to me whispered something, but I didn’t understand. So I leaned over her way and found out that she was trying to ask me if I had an extra pen. She showed me that hers was out of ink and would not write. I happened to have an extra one, so I took it out of my pocket and put it on her desk.Later, after the test papers had been turned in, the teacher asked me to stay in the room when all the other students were dismissed（解散）. As soon as we were alone she began to talk to me about what it meant to grow up; she talked about how important it was to stand on your own two feet and be responsible (负责任) for your own acts. For a long time, she talked about honesty and emphasized（强调）the fact that when people do something dishonest, they are really cheating（欺骗）themselves. She made me promise that I would think seriously（认真地）about all the things she had said, and then she told me I could leave. I walked out of the room wondering why she had chosen to talk to me about all those things.Later on, I found out that she thought I had cheated on the test. When she saw me lean over to talk to the girl next to me, it looked as if I was copying answers from the girl’s test paper. I tried to explain about the pen, but all she could say was it seemed very very strange to her that I hadn’t talked of anything about the pen the day she talked to me right after the test. Even if I tried to explain that I was just doing the girl a favor by letting her use my pen, I am sure she continued（继续）to believe that I had cheated on the test.1. The story took place（发生）exactly ____ .A. in the teacher’s officeB. in an exam roomC. in the schoolD. in the language lab2. The girl wanted to borrow a pen, because ____ .A. she had not brought a pen with herB. she had lost her own on her way to schoolC. there was something wrong with her ownD. her own had been taken away by someone3. The teacher saw all this, so she asked the boy ____ .A. to go on writing his paperB. to stop whisperingC. to leave the room immediatelyD. to stay behind after the exam4. The thing(s) emphasized in her talk was(were) ____ .A. honestyB. sense of dutyC. seriousnessD. all of the above5. The boy knew everything ____ .A. the moment he was asked to stay behindB. when the teacher started talking about honestyC. only some time laterD. when he was walking out of the roomB（7minutes）Some kids start to drink alcohol (酒精) at a young age. They think it is part of becoming an adult. They also think drinking is not that bad because so many people do it. They feel it is not as bad as taking drugs (毒品). It is easy for kids to get liquor （酒精饮料）by using fake identification (伪造证件).Parents may start to notice a change in their child’s behavior if the child starts drinking. Kids who drink sometimes stop doing things they normally liked to do. They may keep telephone calls and meetings a secret and not want anybody to touch their things. They act moody (喜怒无常) and do not have the same eating and sleeping habits.Parents need to stay involved (牵涉) in their kids’lives. They should talk to their children about their problems to be aware of any changes.Parents can be the best protection. Children who get a lot of love can feel good about themselves. It helps them resist（抵抗）doing bad things even when other kids are doing them. Parents can also help set a good example by not drinking and driving. They can have firm rules in the home that everyone follows.Give the children good ideas on how to say “no”to drinking, even when they are at a party. Try not to overreact or panic (惊慌) if the child tries alcohol. How you handle it can affect their attitude. It may be helpful to talk to other parents about setting up curfews (宵禁令) and rules about parties or other events.1. Which of the following is NOT the reason why some kids have an early start of drinking?A. They want to show their maturity (成熟) by drinking alcohol.B. Drinking alcohol is much cooler than taking drugs.C. They are affected by many other people around them.D.

Despit occasional alarms, the country escaped any postwar depression and livedin a state of boom. A n economic survey of the year 1955, a typical ye ar of the 1950’s, may be typical as illustrating the rapid economic growth of the decade. The national output was value at10 percent above that of 1954 (1955 output was estimated at 392 billion dollars). The productionof manufacturers was about 40 percent more than it had averaged in the years immediatelypent about 30billion dollars for new factories and following World War 2. The country’s business smachinery. National income available for spending was almost a third greater than it had been ithad been in 1950. Consumers spent about 256 billion dollars; that is about 700 million dollars aday ,or about twenty-five million dollars every hour , all round the clock. Sixty-five million peopleheld jobs and only a little more than two million wanted jobs but could not find them . Only agriculture complained that it was not sharing in the room. To some observers this was an ominousecho of the mid-1920’s . As farmer’s shre of their products declined , marketing costs rose. But there were , among the observers of the national economy, a few who were not as confident as the majority . Those few seemed to fear that the boom could not last and would eventually lead to theoppsite-depression.1. What is the best title of the passage?a. The Agriculatural Trends of 1950’sb. The Unemployment Rate of 1950’sc. U.S. Economy in the 50’sd. The Federal Budget of 19522. In Line 4 , the word “boom”could best be replaced by______.a. nearby explosionb. thunderous noisec. general public supportd. rapid economic growth3.

The passage states that incom available for spending in the U.S. was greater in 1955 thanin 1950 . How much was it ?a. 60%b. 50%c. 33%d. 90%答案：cdabc三Women are also underrepresented in the administration and this is because there are so few women full professors. In 1985,Regent Beryl Milburn produced a report blasting the University of Texas System adminitration for not encouraging women.The University was rated among the lowest for the system.In a 1987 update ,Milburn commended the progress that was made and called for even more improvement.One of the positive results from her study was a System-wide program to inform women of available administrative jobs.College of Communication Associate Dean Patrica Witherspoon,said it is important that woman be flexible when it comesto relocating if they want to rise in the ranks.Although a woman may face a chilly climate on campus , many times in order for her to succeed , she must rise above the problems around her and concentrate on her work.Until women make up a greater percentage of the senior positions in the University and all academia,inequities will exist."Women need to spend their energies and time doing scholarly activities that are important here at the University." Spirduso said. "If they do that will be successful in this system.If they spend their time in little groups mourning the sexual discrimination that they think exists here, they are wasting valuable study time."1.According to Spirduso,women need to ____.a.produce a report on sexual discriminationb.call for further improvement in their working conditionsc.spend their energies and time fighting against sexual discriminationd.spend more time and energy doing scholarly activities2.From this passage ,we know that _____.a.there are many women full professors in the University of Texasb.women play an important part in adminitrating the Universityc.the weather on the campus is chillyd.women make up a small percentage of the senior positions in the University3.Which of the following statements is true?a.the number of women professors in the University in 1987 was greater than that of 1985b.the number of women professors in the University in 1987 was smaller than that of 1985c.the number of women professors was the same as that of 1985d.more and more women professors thought that sexual discrimination did exit in the University4.One of the positive results from Milburn's study was that _____.a.women were told to con centrate on teir workb.women were given information about available administrative jobsc.women were encouraged to take on all the administrative jobs in the Unversityd.women were encouraged to do more scholarly activities5. The title for this passage should be _______.a.The University of Texasburn's Reportc.Women Professorsd.Sexual Discrimination in Academia答案：ddabd四Today ,as in every other day of the year ,more than 3000 U.S. adlescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime,it can be expected that of these 3000 about 23 will be murdered,30 will die in traffic accidents, and nearly750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweithts all other factors, whether voluntary or involuntary, as a cause of death.Since the late 1970s, when daily smoking among high school seniors reached 30 precent , smoking rates among youth have declined . While the decline is impressive ,several important issues must be raised.First, in the past several years,smoking rates among youth have declined very little. Second,in the late 1970s ,smoking among male high school seniors exceeded that among femaleby nearly 10 percent . The statistic is reversing.Third ,several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent .Finally, thouth significant declines in adolescent smoking have occurred in the past decade,no definite reasons for the decline exist. Within this context,the Naional Cancer Instiute (NCI) beganits current effort to determine the most effecive measures to reduce smoking levesl among youth.1.According to the author, the deaths among youth are mainly caused by _____.a.traffic accidentsb.smoking-related deseasec.murderd.all of these2.Every day there are over_____high school strdents who will become regular smoker.a.75b.23c.30d.30003.By "dropout" the author means______.a.students who failed the examinationb.students who left schoolc.students who lost their wayd.students who were driven out of school4.The reason for declining adolescent smoking is that ________.a.NCI has taken effective measuresb.smoking is prevented among high school seniorsc.there are many smokers who have died of cancerd.none of these5.What is implied but not stated by the author is that ________.a.smoking rates among youth have declined very littleb.there are now more female than male smokers among high school seniorsc.high smoking rates are due to the incease in wealthd.smoking at high school are from low socio-economic backgrounds答案：bdbdb五The food we eat seems to have profound effects on our health.Although science has made enormous steps in making food more fit to eat ,it has, at the same time,made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to dietand forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additivies,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillinto beef and living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue.1.What is the best possible title of the passage?a.Drug and Foodb.Cancer and Healthc.Food and Healthd.Health and Drug2.Which of the following statements is NOT ture?a.Drugs are always given to animals for medical reasonsb.Some of the additives in our food are added to the food itself and some are given to the living animalsc.Researchers have known about the potential dangers of food additives for over thirty-five years.d.Food may cause forty percent of cancer in world.3.How has science done something harmful to mankind?a.Because of science , diseases caused by polluted food haven been virtually eliminated.b.It has caused a lack of information concerning the value of food.c.Because of the application of science,some potentially harmful substances have been added to food.d.The scientists have preserved the color of meats,but not of vegetables.4.What are nitrates used for?a.They preserve flavor in packaged foods.b.They preserve the color of meats.c.They are the objects of research.d.They cause the animals to become fatter.5.The word 'carcinogenic' most nearly means '_____'.a.trouble-makingb.color-retainingc.money-makingd.cancer-causing答案：cacbdWhat is your favourite colour? Do you like yellow , orange ,red? If you do ,you must be anoptimist, a leader, an active person who enjoys life, people and excitement. Do you prefer greysand blues? Then you are probably quiet,shy, and you would rather follow than lead. You tend to be a pessimist. At least, this is what psychologists tell us, and they should know,because they have been seriously studying the meaning of colours preference, as well as the effect that colours have on human beings. They tells us, among other facts,that we do not choose our favourite clour as we grow up----we are born with our preference.If you happen to love brown, you did so, as soon asyou opened your eyes, or at least as soon as you could see clearly.Colours do influence our moods----there is no doubt about it .A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand ,black is depressing. A black bridge overthe Thames River, near London, used to be the scene of more suicides than any other bridge in the area ----until it was repainter green.The number of suicide attempts immediately fell sharply ;perhaps it would have fallen even more if the bridge had been done in pink or baby blue.Light and bright colours make people not only hppier but more active. It is an established fact that factory workers work better,harder ,and have fewer accidents when their machines are painted orange rather than black or grey.1."You would rather follow than red" means_______.a.you don't like to follow othersb.you would be a member rather than a leaderc.you would be afraid of following othersd.you would like to be a leader rather than a follower2.If one enjoys life, one is sure to prefer________.a.red to yellowb.blue to orangec.red to greyd.blue to yellow3."They tell us, among other facts,that we don't choose our favourite colours as we grow up." "Among other facts" means______.a.besides other factsb.in regard to other factsc.not considering other factsd.according to other facts4.Which of the following is facts?a.People's preference of one colour to another is instinctb.People's preference of one colour to another is acquired as they grow up.c.More people happen to love brown because they saw something brown when they were bornd.Colours have little influence on our moods5.Those who committed suicide preferred the bridge over the Thames River near london to others because of _______.a.its shapeb.its structurec.its colourd.its building materials答案：bcaac十二Social customs and ways of behaving change. Things which were considered impolite many years ago are now acceptable. Just a few years ago, it was considered impolite behaviour for a man to smoke on street. No man who thought of himself by smoking when a lady was in a room.Customs also differ from country to country. Does a man walk on the left or the right of a woman in your country? Or doesn't it matter? Should you use both hands when you are eating? Should leave one in your lap,or on the table?The Americans and the British not only speak the same language but also share a large number of social customs. For example, in both America and England people shake hands when they meet each other for the first time. Also, most Englishmen will open a door for a wonman or offer their seat to a woman , and so will most Americans. Promptness is important both in England and in America. That is , if a dinner invitation is for 7 o'clock , the dinner guest either arrives closeto that time or calls up to explain his delay.The important thing to remember about social customs is not to do anything that might make other people feel uncomfortable-----especially if they are your guests. When the food was served , one of the guests strated to eat his peas with a knife . The other guests were amused or shocked , but the host calmly picked up his knife and began eating in the same way. It would have been bad manners to make his guest feel foolish or uncomfortable.1.If one has accepted a dinner invitation ,what should he do if he is tobe late for the dinner?a.He should find an excuseb.He should adk for excuse.c.He should say sorryd.He should telephone to explain his being late.2."It would have been bad manners to make his guests feel foolish or uncomfortable." "Bad manners " means ________.a.uglyb.dishonestc.impolited.shameful3.which of the following do you think is the best tiltle for this passage?a.Social Customs and Customsb.Social Lifec.American and British Customsd.Promptness Is Important4.According to the text, the best host_______.a.tries his best to make his guests feel comfortableb.makes his guests feel excitedc.tries to avoid being naughty to his guestsd.tries to avoid being foolish5.The author of this article may agree with which of the following?a.The guest who ate his peas with a knifeb.The other guests who were amused or shockedc.The host who picked up his knife and began eating in the same wayd.None of the above答案：dcaac十三New Orleans, Louisiana, was established as part of the French Empire in 1718.Its location on the east bank of the Mississippi River gave it control of the American hinerland and it became strategically important to many nations. It was transferred from France to Spain, returned to France,and finally sold by Napoleon to the United States in 1803. The city was the site of a famous battle fought in 1815 between the British, who hoped to control it , and the Americans under General And rew Jackson.The riverbed of the Mississippi is constantly silting and the river is now actually higher thanthe city. Levees hold back the river and giant pumps are used to move water from the city into the river.Although New Orleans haas beena part of the United States for almost two centuries, its population takes great pride in its French heritage. Louisiana still retains parts of the Code Napoleon which,form many years,was its only law.New Orleans is carefree city and it boasts its hot, spicy Creole seafood and its native Dixieland Jazz. The jackson Square neighborhood maintains its French colonial homes and in other sections are pre-Civil War mansions. Visitors are surprised to find that behind this interesting facade of yesteryear, is a busy industrial and port city. Grain and coal come from the Midwest and foreigh cargoes are unloaded here. New Orleans is no longer a sleepy Southern town----but it's still fun to visit.1.What accounts for the levees and pumps in New Orleans?a.The Mississippi frequently floods the city.b.The riverbed has raised inthe past 200 years.c.The torrential rains flood the city frequently.d.The high humidity cannot otherwise be comtrolled.2.The battle of New Orleans was fought by jackson against______.a.Franceb.Britainc.Spaind.The North3.The Code Napoleon was _______.a.an agreement to sell Louisianab.a body of lawsc.a city pland.a military code for the army4.Which of the following elements does not apply to the attiude of the inhabitants of New Orleans?a.Pride in their French heritage.b.A desire to retain picturesque colonial buildings.c.A refusal to engage in trade and commerced.A praising of Dixieland Jazz.5.Tourists visiting New Orleans are surprised to encounter_____.a.Creole foodb.Dixieland jazzc.bustling cityd.authentic colonial homes答案：bbbcc十四The United States is on the verge of losing its leading place in the world's technology. So says more than one study in recent years. One of the reasons for this decline is the parallel decline in the number of U.S. scientists and engineers.Since 1976,employment of scientists and engineers is up 85 percent. This trend is expected to continue. However, the trend shows that the number of 22-year-olds--the near term source of future PH.D.s-is declining. Further adding to the problem is the increased competition for these candidates from other fields-law,medicine,business,etc. While the number of U.S. PH.D.s in science and engineering declines,the award of PH.D.s to foreign nationals is increasing rapidly.Our inability to motivate students to pursue science and engineering careers at the graduate level is compounded because of the intense demand industry has for bright Bachelor's and Master's degree holders. Too often, promising PH.D.candidates, confronting the cost and financial sacrifice of pursuing their education,find the attraction of industry irresistible.1.The U.S.will come to lose its leading place in technology probably because ________.a. the number of PH.D. degree holders is decliningb. the number of scientists and engineers is decreasingc. the number of 22-year-ilds is decliningd. scientists and engineers are not employed2.The field of science and engineering is facing a competition from ________ .a. technologyb. foreign nationalsc. such fields as law, medicine and businessd. postgraduatesrge-scale enterprises now need _______.a. bright graduates and postgraduatesb. new inventionsc. advanced technologyd. engineers4.Many promising postgraduates are unwilling to pursue a PH.D. degree because _________.a. they are not encouraged to be engaged in scienceb. industry does not require PH.D. holdersc. they have financial difficultiesd. they will spend much time and energy completing PH.D.5.PH.D. candidates "find the attraction of industry irresistible" means that _________.a. they find industry is attracting more and more college studentsb. they don't think they can prevent themselves from working for industryc. they cannot resist any attraction from all sidesd. they cannot work for industry any longer答案：bcadb十五Newdays,a standard for measuring power has changed.These changes foretell a new standard for measuring power.No longer will a nation's political influence be based solely on the strength ofits military forces. Of course, military effectiveness will remain a primary primary measure of power.But political influence is also closely tied to industrial competitiveness. It's often said that without its military the Soviet Union would really be a third-world nation. The new standard ofopwer and influence that is evolving now places more emphasis on the ability of a country to compete effectively in the economic markets of the world.America must recognize this new course of events. Our success in shaping world events over the past 40 years has been the direct result of our ability to adapt technology and to take advantage of the capabilities of our people for the purpose of maintaining peace. Our industrial prowess over most of this period was unchallenged. It is ironic that it is just this prowess that has enabled other countries to prosper and in turn to threaten our industrial leadership.The competitiveness of America's industrial base is an issue bigger than the Department of Defense and is going to require the efforts of the major institutional forces in our society-government,industry,and education. That is not to say that the Defense Department will not be a strong force in the process because we will. But we simply cannot be, nor should we be, looked upon by others as the savior of American industry.1. Now a nation's political influence depends on _________.a. the strength of its military forcesb. its ability to compete in industryc. economic marketsd. both a and b2. The Soviet Union was not listed as a third-world nation just because of _________.a. its powerful military forcesb. its vast landc. its industrial competitivenessd. its contributions to world peace3. The author indicates that ______ is threatening American political power.a. other countriesb. the declining U.S. industrial basec. a new standard for measuring powerd. less advanced technology4. America succeeded in shaping world events over past 40 years probably because of ___________.a. its ability to adapt technologyb. its ability to take advantage of the capabilities of its peoplec. its ability to compete in the world marketsd. both a and b5. The purpose of writing this article is __________.a. to draw the readers' attention to a new standard for measuring powerb. to demonstrate American political influence in the worldc. to emphasize that efforts must be made to strengthen the declining U.S. industrial based. to show American industrial prowess答案：dabdc。

英语四级阅读理解试题带答案英语四级阅读理解试题：【原文】How to Deal With Difficult PeopleIn New York City one day, a businesswoman got into a taxi. Because it was rush hour and she was hurrying for a train, she suggested a route. "Ive been a cabby(车夫) for 15 years!" the driver yelled. "You think I dont know the best way to go?"The woman tried to explain that she hadnt meant to offend him, but the driver kept yelling. She finally realized he was too upset to be reasonable. So she did the unexpected. "You know, youre right," she told him. "It must seem dumb for me to assume you dont know the best way through the city. "Taken aback, the driver flashed his rider a confused look in the rear-view mirror, turned down the street she wanted and got her to the train on time. "He didnt say another word the rest of the ride," she said, "until I got out and paid him. Then he thanked me. "When you encounter people like this cab driver, theres an irresistible urge to dig in your heels. This can lead to prolonged arguments, soured friendships, lost career opportunities and broken marriages. As a clinical psychiatrist, Ive discovered one simple but extremely unlikelyprinciple that can prevent virtually any conflict or other difficult situation from becoming a recipe for disaster.The key is to put yourself in the other persons shoes and look for the truth in what that person is saying. Find a way to agree. The result may surprise you.Sulkers Steves 14-year-old son, Adam, had been irritable for several days. When Steve asked why, Adam snapped, "Nothings wrong! Leave me alone!" and stalked off to his room.We all know people like this. When theres problem, they may sulk(生闷气) or act angry and refuse to talk.So whats the solution? First, Steve needs to ask himself why Adam wont talk. Maybe the boy is worried about something that happened at school. Or he might be angry at his dad but afraid to bring it up because Steve gets defensive whenever he is criticized. Steve can pursue these possibilities the next time they talk by saying, "I noticed youre upset, and I think it would help to get the problem out in the open. It may be hard because I havent always listened very 58well. If so, I feel bad because I love you and dont want to let you down. "If Adam still refuses to talk, Steve can take a different tack: "Im concerned about whats going on with you, but we can talk things over later, when youre more in the mood. "This strategy allows both sides to win: Steve doesnt have to compromise on the principle that ultimately the problem needs to be talked out and resolved. Adam saves face by being allowed to withdraw for a while.Noisy critics. Recently, I was counselling a businessman named Frank who lends to be overbearing(专横的) when hes upset. Frank told me that I was too absent-minded with money and that he shouldnt have to pay at each of our sessions. He wanted to be billed monthly.I felt annoyed because it seemed Frank always had to have things his way. I explained that I had tried monthly billing, but it hadnt worked because some patients didnt pay. Frank argued that he had impeccable (无可挑剔的 ) credit and knew much more about credit and billing than I did.Suddenly I realized I was missing Franks point. "You are right," I said. " Im being defensive. We should focus on the problems in your life and not worry so much about money. "Frank immediately softened and began talking about what was really bothering him, which were some personal problems. The next time we met, he handed me a check for 20 sessions in advance!There are times, of course, when people are unreasonably abusive and you may need to just walk away from the situation. But if the problem is one that you want solved, its important to allow the other person to keep some self-esteem. Theres nearly always a grain of truth in the other persons point of view. If you acknowledge this, he or she will be less defensive and more likely to listen to you.Complainers. Brad is a 32-year-old Detroit chiropractor (按摩师) who recently described his frustration with a patient of his: "I ask Mr. Barry, How are you doing? and he dumps out his whole life story-his family problems and his financial difficulties. I give him advice, but he ignores everything I tell him. "Brad needs to recognize that habitual complainers usually dont want advice. They just want someone to listen and understand. So Brad might simply say : "sounds like a rough week, Its no fun to have unpaid bills, people nagging you, and this pain besides. " The complainer will usually run out of gas and stop complaining. The secret is not to give advice. Just agreeing and validating a persons point of view will make that person feel better.Demanding friends. Difficult people arent always -, angry or just complaining. Sometimes they are difficult because of the demands they place upon us. Maybe a friend puts you on the spot with a request to run an errand for him while hes out of town. If you have a crowded schedule, you may agree but end up angry and resentful. Or if you say no in the wrong way, your friend may feel hurt and unhappy. The problem is that, caught off guard, you dont know how to deal with the situation in a way that avoids bad feelings.One method Ive found helpful is "punting". Youre punting when you tell the person you need to think about the request and that youll get back about it. Say a colleague calls and pressures me to give a lecture at his university. Ive learned to say, "Im flattered that you thought of me. Let me check my schedule, and Ill call you back. "This gives me time to deal with any feelings of guilt if I have to say no. Suppose I decide it is better to decline; punting allow me to plan what I will say when I call back, "I appreciate being asked," I might indicate, "but I find Im over-committed right now. However, I hope youll think of me in the future. "Responding to difficult people with patience and empathy can be tough, especially when you feel upset. But the moment you give up your need to control or be right, the other person will begin relaxing and start listening to you. The Greek philosopher Epictetus understood this when he said nearly 2, 000 years ago, "If someone criticizes you, agree at once. Mention that if only the other person knew you well, there would be more to criticize than that !"Real communication results from a spirit of respect for yourself and for the other person. The benefits can be amazing.英语四级阅读理解试题：【题目】1. The principle the writer has discovered to stop any conflict from going worse is to find a way to agree.2.

Man-lifting kites were developed in ancient times,again by the Chinese, for getting information from walled cities and army camps.In fact,as recently as world2,German U-boats flew kites from their towers to lift people into the air to watch the lanD.These kites,which are no longer in existence,were made of light-weight cloth.They were much larger and stronger than the Chinese ones.Their design,however,was simply that of the cutter kite.Smaller in size,this type of kite is still very popular as a toy for children,being easy to make with a diamond-shapedframe,no wings and brown-paper covering.Box-kites are another type of kite found in toy shops today.The first box-kite,named for its box-like body,was developed in the nineteenth century to test theories of flight and this type of cotton-covered kite greatly assisted the success of early aeroplane.These kites are the ancestors of a heavier version of the box-kite,which consists of two main sections,placed side by side. Developed for the peacetime purpose of fishing in strong sea wind,it is the only modern kite described which has practical value.A long-lasting plastic material has to be used for this kite,which carries fishing lines.1.The ancient Chinese bird-kites were usually made of light frames covered with_____.A.silkB.paperC.clothD.plastic2.The kites used by German U-boats in would war2for the military purpose were made of_____.A.brown paperB.plastic materialC.light-weight clothD.traditional silk3.The ancient Chinese man-lifting kites were used_____.A.to carry ropes across rivers and valleysB.for the military purposeC.as toy for childrenD.for fishing in strong sea wind4.Which of the following statements is not ture?A.The frame of a kite is attached to long string held in the hand or woundon drum.B.The ancestor of the double box-kite.C.The cutter kite has a diamond-shaped body but no wings.D.The current folding kite is developed to test theories of flight.5.The best title for this may be______.A.The ancestors of modern kitesB.The history of the chinese kitesC.different types and uses of kitesD.the different between ancient and modern kites.二、完型填空完型填空（一）Dalton wondered why the heavier and lighter gases in the atmosphere did not separate as oil andwater do.He finally concluded that the constituent 1must exist in the form of2particles or atoms andthat these3be completely mixed together in the4.This threw a new light in5laws of definiteproportions.It was6necessary to suppose that the atoms7 combinesintossmall groups of uniform8andso form more complex substance;
