The most interesting architectural phenomenon of the 1970's was the enthusiasm for refurnishing older building. Obviously, this was not an entirely new phenomenon. What is new is the whole scale in reusing the past, in recycling, in adaptive rehabilitation (更新). A few trial efforts, such as Ghirardelli Square in San Francisco, proved their financial feasibility in the 1960's, but it was in the 1970's, with strong government support through tax incentives and rapid depreciation (贬值) , as well as growing interest in ecology (生态) issues, that recycling became a major factor on the urban scene. One of the most comprehensive ventures was the restoration and transformation of Boston's eighteenth century Faneuil Hall and the Quincy Market, designed in 1824. This section had fallen on hard times, but beginning with the construction of a new city hall immediately nearby, it has returned to life with the intelligent reuse of these fine old buildings under the design leadership of Benjamin Thompson. He has provided a marvelous setting for dining, shopping, professional office, and simply walking.Butler Square, in Minneapolis, serves as an example of major changes in its complex of offices, commercial space, and public amenities carved out of a massive pile designed in 1906 as a hardware warehouse. The exciting interior timber structure of the building was highlighted by cutting light courts through the interior and adding large skylights.San Antonio, Texas, offers a big object lesson for numerous other cities combating urban decay. Rather than bringing in the bulldozers ( 推土机) , San Antonio's leaders rehabilitated existing structures, while simultaneously cleaning up the San Antonio River, which runs through the business district.26. The main idea of the passage is_______.A. during the 1970's, old building in many cities were recycled for modern useB. recent interest in ecology issues has led to the cleaning up of many riversC. the San Antonio example shows that bulldozers are not the right way to fight urban decayD. strong government support has made adaptive rehabilitation a reality in Boston27. According to the passage, Benjamin Thompson was the designer for a project inA. BostonB. San FranciscoC. MinneapolisD. San Antonio28. The space at Quincy Market is now used as_______.A. Boston's new city hallB. sports and recreational facilitiesC. commercial and industrial warehousesD. restaurants, offices, and stores29. What is the author's opinion of the San Antonio's project?A. It is clearly the best of the projects discussed.B. It is a good project that could be copied by other cities.C. The extensive use of bulldozers made the project unnecessarily costly.D. The work done on the river was more important than work done on thebuildings.30. The passage states that the San Antonio project differed from those in Boston and Minneapolis in that_______.A. it consisted primarily of new buildingsB. it occurred in the business districtC. it involved the environment as well as buildingsD. it was designed to combat urban decay答案:26.

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 ,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.to the author, the deaths among youth are mainly caused by _____. accidentsdeseaseof theseday there are over_____high school strdents who will become regular smoker."dropout" the author means______.who failed the examinationwho left schoolwho lost their waywho were driven out of schoolreason for declining adolescent smoking is that ________.has taken effective measuresis prevented among high school seniorsare many smokers who have died of cancerof theseis implied but not stated by the author is that ________.rates among youth have declined very littleare now more female than male smokers among high school seniors smoking rates are due to the incease in wealthat high school are from low socio-economic backgrounds答案:bdbdb大学英语四级阅读理解试题40篇之五(含答案)The food we eat seems to have profound effects on our 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 labelsof 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.is the best possible title of the passageand Foodand Healthand Healthand Drugof the following statements is NOT tureare always given to animals for medical reasonsof the additives in our food are added to the food itself and some are given to the living animalshave known about the potential dangers of food additives for over thirty-five years.may cause forty percent of cancer in world.has science done something harmful to mankindof science , diseases caused by polluted food haven been virtually eliminated.has caused a lack of information concerning the value of food. of the application of science,some potentially harmful substances have been added to food.scientists have preserved the color of meats,but not of vegetables. are nitrates used forpreserve flavor in packaged foods.preserve the color of meats.are the objects of research.cause the animals to become fatter.word 'carcinogenic' most nearly means '_____'.答案:cacbd大学英语四级阅读理解试题40篇之六(含答案)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 tobe .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 serious conditions as high blood pressure and heart disease have established links with 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.are finding less and less time for relaxing themselves because_____.do not know how to enjoy themselvesdo not believe that relaxation is important for healthare travelling fast all the timeare becoming busier with their workto the writer ,the most important character for a good manager is his ________.fearing stressthe art of relaxationsense of responsibilitycontrol over performanceof the follwing statements is turecan find some ways to avoid stressis always harmful to peopleis easy to change the hagit of keeping oneself busy with work. people can withstand different amounts of stressParagraph 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"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:dadbc大学英语四级阅读理解试题40篇之七(含答案)In 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 . 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 late1960s, was based on the ideas of psychologist 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.did some young Americans decide to "drop out" of scoiety during the 1960swere not satisfied with American society.wanted to grow marijuana.wanted to go to the Vietnam War.did not want all people to be equal.did the members of the Hog Farm commune livedome-shaped houseold school husesa farm inTennesseean archology in Arizonagave the people of Drop City the idea to bulid dome-shaped house SoleriGaskinFullerwas the Twin Oaks commune base onphilosophy of "do your own thing"in the late 1960sideas of psychologistbelief that people must live closely togerher.is an "archology"person who studies archaeologylarge building where people live closely togethercity in A rizonatechnique to contorl people答案:abdcb大学英语四级阅读理解试题40篇之八(含答案)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 developand 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 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 enviromental difference continued until the twins were in their late teens, when they were giben tesets to measure their intelligence. Mark's . was 125, twenty-five points higher than the average and fully forty points higher than his identical brother.

"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."

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 tinyamount 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 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. long run, the most insoluble problem caused by population growth on earth will probably be the lack of ______.Sagan believes that Venus might be colonized from earth because _____might be possible to change its atmosphereatmosphere is the same as the earth'sis a good supply of water on Venusdays on Venus are long enoughVenus there is a lot of ________.dioxidemonoxideare plants that can____.in very hot temperaturesin very cold temperaturesoxygenof the above5.

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 tellus, 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 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 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_______.don't like to follow otherswould be a member rather than a leaderwould be afraid of following otherswould like to be a leader rather than a followerone enjoys life, one is sure to prefer________.to yellowto orangeto greyto yellow3."They tell us, among other facts,that we don't choose our favourite colours as we grow up."

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 tableThe 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.one has accepted a dinner invitation ,what should he do if he is tobe late for the dinnershould find an excuseshould adk for excuse.should say sorryshould telephone to explain his being late.2."It would have been bad manners to make his guests feel foolish or uncomfortable."

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. 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:dadbc七In 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: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.

Behaviorists, who study the relation between actions and, argue that rewards can improve performance at work and school. Some other researchers who study various aspects of mental life, maintain those rewards often destroy creativity byencouraging dependence on approval and gifts from others.The latter view has gained many supporters, especially among educators. But the careful use of small monetary rewards sparks in grade-school children suggesting that properly presented inducements indeed aid inventiveness, according to a study in the June Journal Personality and Social Psychology.“If they know they're working for a reward and can focus on a relatively challenging task, they show the most creativity,” says Robert Esenberger of the University of Delaware in Newark. “But it's easy to kill creativity by giving rewards for poor performance or creating too much anticipation for rewards.”A teacher who continually draws attention to rewards or who hands out high grades for ordinary achievement ends up with uninspired students, Esenberger holds. As an example of the latter point, he notes growing efforts at major universities to tighten grading standards and restore falling grades.In earlier grades, the use of so-called token economics, in which students handle challenging problems and receiveperformance-based points toward valued rewards, shows promise in raising effort and creativity, the Delaware psychologist claims.1. Psychologists are divided with regard to their attitudes toward ____.A) the choice between spiritual encouragement and monetary rewardsB) the appropriate amount of external rewardsC) the study of relationship between actions andD) the effects of external rewards on students' performance2. What is the view held by many educators concerning external rewards for students?A) They approve of external rewards.B) They don't think external rewards.C) They have doubts about external rewards.D) They believe external rewards can motivate small children, but not college students.3. According to the result of the study mentioned in the passage, what should educators do to stimulate motivation and creativity?A) Give rewards for performances which deserve them.B) Always promise rewards.C) Assign tasks which are not very challenging.D) Be more lenient to students when mistakes are made.4. It can be inferred from the passage that major universities are trying to tighten their grading standards because they believe ____.A) rewarding poor performance may kill the creativity of students’B) punishment is more effective than rewardingC) failing uninspired students helps improve their overall academic standardsD) discouraging the students anticipation for easy rewards is matter of urgency5.Which of the following facts about “token economics” is not correct?A) Students are assigned challenging tasks.B) Rewards are given for good performances.C) Students are evaluated according to the effort they put into the task.D) With token economics, students’ creativity can be enhanced.。

You are required to select one word for each blank from a list of choices given in a word bank following the passage. You may not use any of the words in the bank more than once.Passage:The development of e-commerce has dramatically transformed the retail industry. Traditional brick-and-mortar stores have been supplemented, and in some cases, replaced by online platforms. This shift has brought about significant changes in the way consumers shop and businesses operate.One of the main benefits of e-commerce is the convenience it offers. Consumers can shop from the comfort of their homes at any time of day, without the need to travel to a physical store. This has particularly benefited those with busy schedules or limited mobility. Additionally, e-commerce allows for a wider selection of products than might be available in local stores, often at more competitive prices.However, the rise of e-commerce has also introduced challenges. The anonymity of online transactions can lead to issues of trust, with consumers sometimes hesitant to purchase from unfamiliar websites. Furthermore, the increased competition has forced many small businesses to either adapt to the digital marketplace or face closure.In conclusion, while e-commerce has revolutionized the retail industry and brought numerous benefits to consumers, it is not without its challenges. Businesses must continue to evolve to meet the demands of this rapidly changing landscape.Word Bank:A) convenienceB) competitionC) transactionsD) transformedE) operateF) mobilityG) adaptH) hesitantI) unfamiliarJ) widerQuestions:1) The development of e-commerce has _______ the retail industry.2) One of the main benefits of e-commerce is the _______ it offers.3) Consumers can shop from home, which is particularly beneficial for those with limited _______.4) The anonymity of online _______ can lead to issues of trust.Section BDirections:In this section, you will read several passages. Each passage is followed by several 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.Passage One:The tourism industry has seen significant growth over the past few decades, driven by the increasing availability of affordable travel options and the rise of social media. These factorshave made it easier than ever for people to explore new destinations and share their experiences with others.One of the most notable trends in recent years is the rise of "sustainable tourism." This approach emphasizes minimizing the environmental impact of travel while supporting local communities. Sustainable tourism can include practices such as choosing eco-friendly accommodations, participating in conservation efforts, and respecting local cultures. However, the growth of tourism has also led to challenges. Popular destinations can become overcrowded, leading to damage to natural environments and cultural sites. In some cases, the influx of tourists can even disrupt local communities, causing resentment among residents. In conclusion, while tourism offers many benefits, it is important to approach travel responsibly to ensure that destinations can be enjoyed by future generations. Questions:1) What has contributed to the significant growth of the tourism industry?A) The decline in travel costs and the popularity of social media.B) The development of new transportation methods.C) The increase in luxury travel options.D) The promotion of international tourism by governments.2) What is a key aspect of sustainable tourism?A) Visiting as many destinations as possible.B) Minimizing environmental impact and supporting local communities.C) Staying in luxury hotels and resorts.D) Traveling to remote and unspoiled locations.3) What is one of the challenges caused by the growth of tourism?A) The decline in international travel.B) The negative impact on local cultures and environments.C) The rise in travel-related costs.D) The decrease in travel safety.4) How can travelers ensure that destinations remain enjoyable for future generations?A) By visiting only popular tourist spots.B) By choosing environmentally friendly travel options.C) By limiting the duration of their trips.D) By avoiding travel during peak seasons.Passage Two:The concept of work-life balance has become increasingly important in modern society. As technology continues to blur the lines between work and personal life, many people struggle to find time for relaxation and leisure. This issue is particularly prevalent in countries where long working hours are the norm.One of the main challenges of achieving work-life balance is the expectation to be constantly available. With the advent of smartphones and email, employees are often expected to respond to work-related communications outside of regular business hours. This can lead to burnout and decreased job satisfaction.Employers are beginning to recognize the importance of work-life balance for employee well-being and productivity. Some companies have implemented policies such as flexible working hours, remote work options, and mandatory vacation time to help employees achieve a healthier balance.In conclusion, work-life balance is essential for maintaining both physical and mental health.

They wanted to end the Vietnam War and to make all of the people in the . 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 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 willall become one.did some young Americans decide to "drop out" of scoiety during the 1960s?were not satisfied with American society.wanted to grow marijuana.wanted to go to the Vietnam War.did not want all people to be equal.did the members of the Hog Farm commune live?dome-shaped houseold school husesa farm inTennesseean archology in Arizonagave the people of Drop City the idea to bulid dome-shaped house?SoleriGaskinFullerwas the Twin Oaks commune base onphilosophy of "do your own thing"in the late 1960sideas of psychologistbelief that people must live closely togerher.is an "archology"person who studies archaeologylarge building where people live closely togethercity in A rizonatechnique 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 theidentical 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 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 enviromental difference continued until the twins were in their late teens, when they were giben tesets to measure their intelligence. Mark's . 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.selection can best be titled_________.Your Intelligenceand EnvironmentCase of Peter and Markthe brain Influences Intelligencebeststatement of the main idea of this passage is that _____.brains differ considerablybrain a person is born with is improtant in determining his intelligenceis crucial in determining a person's intelligenced. persons having identical brains will have roughly the same intelligenceto the passage , the average _____.case history of the twins appears to support the conclusion that _______.with identical brains seldom test at same levelindividual's intelligence is determined only by his enviromentof opportunity blocks the growth of intelligenceof enviroment produce changes in the structure of the brainpassage suggests that an individual 's be predicted atbirththe same throuthout his lifebe increased by educationdetermined 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 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 motherwas in an especially cheerful mood, "Your father has at last to decided to stop smoking."

The study, published in the Journal of Animal Ecology, found that ants have two distinct(显著的)effects on their local environment. Firstly, through moving of soil by nest building2 activity and by collecting food they affect the level of nutrients(营养物)in the soil. This can indirectly impact the local populations of many animal groups, from decomposers(腐生物,分解体)to species much higher up the food chain. Secondly, they prey(捕食) on a wide range of other animals, including larger prey which can be attacked by vast numbers of ant workers. Dirk Sanders, an author of the study from the university’s Centre for Ecology and Conservation, said: "Ants are very effective predators which thrive in huge numbers. They’re also very terr itorial3 and very aggressive, defending their resources and territory against other predators. All of this means they have a strong influence on their surrounding area." "In this research, we studied for thefirst time how big this impact is and the subtleties(微妙) of it. What we found is that despite being predators, their presence can also lead to an increase in density anddiversity of other animal groups4. They genuinely play a key role in the local environment, having a big influence on the grassland food web," Sanders said. The study, carried out in Germany, studied the impact of the presence of different combinations and densities of black garden ants and common red ants, both species which can be found across Europe, including in the UK. It found that a low density of ants in an area increased the diversity and density of other animals in the local area, particularly the density of herbivores(食草动物) and decomposers. At higher densities ants had no or the opposite effect, showing that predation is counteracting the positive influence. Dr Frank van Veen, another author on the study, said: "What we find is that the impact of ants on soil nutrient levels has a positive effect on animal groups at low levels, but as the number of ants increases, their predatory impacts have the bigger effect — thereby counteracting the positive influence via ecosystem engineering." Ants are important components of ecosystems not only because they constitute a great part of the animal biomass5 (生物量) but also because they act asecosystem engineers. Ant biodiversity6(生物多样性)is incredibly high and these organisms are highly responsive(敏感的,易受影响的) to human impact, which obviously reduces its richness. However, it is not clear how such disturbance damages the maintenance of ant services to the ecosystem7.Ants are important in below ground processes8 through the alteration of the physical and chemical environment and through their effects on plants, microorganisms, and other soil organismsThe standardized educational or psychological tests, which are widely used to aid in selecting, assigning or promoting students, employees and military personnel, have been the target of recent attacks in books, magazines, the daily press, and even in Congress. The target is wrong, for, in attacking the tests, critics divert attention from the fault that lies with ill-informed or incompetent users. The tests themselves are merely tools. Whether the results will be valuable, meaningless, or even misleading depends partly upon the tool itself but largely upon the user. All informed predictions of future performance are based upon some knowledge of relevant past performance. How well the predictions will be validated by later performance depends upon the amount, reliability and appropriateness of the information used and on the skill and wisdom with which it is interpreted. Anyone who keeps careful score knows that the information available is always incomplete and that the predictions are always subject to error. Standardized tests should be considered in this context: they provide a quick, objective method of getting some kind of information about what a person has learned, the skills he has developed, or the kind of person he is. The information so obtained has, qualitatively, the same advantages and shortcomings as other kinds of information. Whether to use tests, other kinds of information, or both in a particular situation depends, therefore, upon the empirical evidence concerning comparative validity and upon such factors as cost and availability. In general, the tests work most effectively when the traits or qualities to be measured can be most precisely defined ( for example, ability to do well in a particular course of training program ) and leasteffectively when what is to be measured or predicted cannot be well defined, for example, personality or creativity. Properly used, they provide a rapid means of getting comparable information about many people. Sometimes they identify students whose high potential has not been previously recognized.The modern sailing ship was developed by a man who never went to sea.He was Prince Henry of Portugal,the younger son of the Partuguese king and an English princess.Prince Henry lived in the fifteenth a boy he became devoted to the sea,and he dedicated himself to improving the design of ships and the methods of sailing 1416,when he was twenty two,Henry founded a school for mariners, to which he invited everyone who could help him—Jewish astronomers,Italian and Spanish sailors, and Arab mathematicians and map makers who knew to use the crudecompass of the day and could improve it.Henry’s goal was to design and equip vessels that would be capable of making long ocean voyages without having to hug the caravel carried more sail and was longer and slimmer than any ship then made,yet was tough enough to withstand gales at also developed the carrack,which was a slower ship,but one that was capable of carrying more cargo.To Prince Henry the world owes credit for development of craft that made oceanic exploration lives in history as Henry the Navigator.The modern sailing ship was developed by a man who never went to sea.He was Prince Henry of Portugal,the younger son of the Partuguese king and an English princess.Prince Henry lived in the fifteenth a boy he became devoted to the sea,and he dedicated himself to improving the design of ships and the methods of sailing 1416,when he was twenty two,Henry founded a school for mariners, to which he invited everyone who could help him—Jewish astronomers,Italian and Spanish sailors, and Arab mathematicians and map makers who knew to use the crudecompass of the day and could improve it.Henry’s goal was to design and equip vessels that would be capable of making long ocean voyages without having to hug the caravel carried more sail and was longer and slimmer than any ship then made,yet was tough enough to withstand gales at also developed the carrack,which was a slower ship,but one that was capable of carrying more cargo.To Prince Henry the world owes credit for development of craft that made oceanic exploration lives in history as Henry the Navigator.十Now let us look at how we read. When we read a printed text, our eyes move across a page in short, jerky movement. We recognize words usually when our eyes are still when theyfixate. Each time they fixate, we see a group of words. This is known as the recognition span or the visual span. The length of time ofr which the eyes stop ---the duration of the fixation ----varies considerably from person to person. It also vaies within any one person according to his purpose in reading and his familiarity with the text. Furthermore, it can be affected by such factors as lighting and tiredness. Unfortunately, in the past, many reading improvement courses have concentrated too much on how our eyes move across the printed page. As a result of this misleading emphasis on the purely visual aspects of reading, numerous exercises have been devised to train the eyes to see more words at one fixation. For instance, in some exercises, words are flashed on to a screen for, say, atenth or a twentieth of a second. One of the exercises has required students to fix their eyes on some central point, taking in the words on either side. Such word patterns are often constructed in the shape of rather steep pyramids so the reader takes in more and more words at each successive fixation. All these exercises are very clever, but it’s one thing to improve a person’s ability to see words and quite another t hing to improve his ability to read a text efficiently. Reading requires the ability to understand the relationship between words. Consequently, for these reasons, many experts have now begun to question the usefulness of eye training, especially since any approach which trains a person to read isolated words and phrases would seem unlikely to help him in reading a continuous textIf 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 the middle of the 21st century,if present trends continue, we will have used up all the oil that drives our cars,for 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 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 andin a few years something like earth will be reproduced on Venus.long run, the most insoluble problem caused by population growth on earth will probably be the lack of ______.Sagan believes that Venus might be colonized from earth because _____might be possible to change its atmosphereatmosphere is the same as the earth'sis a good supply of water on Venusdays on Venus are long enoughVenus there is a lot of ________.dioxidemonoxideare plants that can____.in very hot temperaturesin very cold temperaturesoxygenof the above5. Man can land on Venus only when_______.algae have done their workatmosphere becomes cooleroxygenrains there答案:cabddHeroin addictions today is found chiefly among young men of minority groups inghetto(犹太人区) the more than 60,000 known addicts,more than half live in New York of them live in New York figures show that more than half of the addicts are under 30 years of age.Narcotic addiction in the United States is not limted to heroin middle-aged and older people who take narcotic drugs regularly to relieve pain can also become do some people who can get drugs easily,such as doctors,nurses,and show that this type of addict has personality and emotional problems very similar to those of other regular narcotic users.Many addicts admit that getting a continued supply is the main object of their addict’s concentration on getting drugs often prevents continuing an education or workingat a health is often may be sick one day from the effects of withdrawal and sick the next day from an show that an addict’s life span may be shortened by 15 to 20 addict isusually in trouble with the family and almost always in trouble with the law.Some studies suggest that many of the known narcotic addicts had some trouble with the law before they became addicted,they may become even more involved with crime becauseit costs so much to support the heroin habit.Most authorities agree that the addict’s involvement with crime is not a direct eff ect of the drug to crime is usually the only way to get that much addicts’ crimes are nearly always thefts or other crimes against property.Federal penalties for illegal narcotics usage were established under the Harris on Act of Act provides that illegal possession of narcotics is punishable by fines and/or can range from 2 to 10 years for the first offense,5 to 20 years for the second,and 10 to 20 years for further offenses.Illegal sale of narcotics can mean a fine of $20,000 and a sentence from 20 to 40 years for later person who sells narcotics to someone under 18 is refused parole and probation,even for the first the drug is heroin,he can be sentenced to life imprisonment or to death.Scientists say they have discovered hints of alien life on the Saturn's moon. The discovery of a sort of life was announced after researchers at the US space agency,NASA,analyzed data from spacecraft Cassini,which pointed to,the existence of methane-based form of life on Saturn's biggest moon.Scientists have reportedly discovered clues showing primitive alien beings are"breathing" in Titan's dense atmosphere filled with hydrogen.They argue that hydrogen gets absorbed before hitting Titan's planet-like surface covered with methane lakes and rivers. This,they say,points to the existence of some"bugs" consuming the hydrogen at the surface of the moon less than half the size of the Earth."We suggested hydrogen consumption because it's the obvious gas for life to consume on Titan,similar to the way we consume oxygen on Earth,"says NASA scientist Chris McKay."If these signs do turn out to be a sign of life,it would be doubly exciting because it would represent a second form of life independent from water-based life on Earth."To date,scientists havenot yet detected this form of life anywhere,though there are liquid- water-based microorganisms on Earth that grow well on methane or produce it as a waste product. On Titan, where temperatures are around 90 Kelvin(minus 290 degrees Farenheit),a methanebased organism would have to use a substance that is liquid as its medium for living processes, but not water itself. Water is frozen solid on Titan's surface and much too cold to support life as we know it.Scientists had expected the Sun's interactions with chemicals in the atmosphere to produce a coating of acetylene on Titan's surface. But Cassini detected no acetylene on the surface.The absence of detectable acetylene on the Titan's surface can very well have a non-biological explanation,said Mark Allen,a principal investigator of the NASATitan team."Scientific conservatism suggests that a biological explanation should be the last choice after all non-biological explanations are addressed,"Allen said. "We have a lot of work to do to rule out possible non-biological explanations. It is more likely that a chemical process,without biology,can explain these results."1. Passage OneUnless we spend money to spot and prevent asteroids(小行星)now,one might crash into Earth and destroy life as we know it,say some scientists.Asteroids are bigger versions of the meteoroids(流星)that race across the night orbit the sun far from Earth and don't threaten there are also thousands whose orbits put them on a collision course with Earth.Buy $ 50 million worth of new telescopes right spend $ 10 million a year for the next 25 years to locate most of the space the time we spot a fatal one,the scientists say,we'll have a way to change its course.Some scientists favor pushing asteroids off course with nuclear the cost wouldn't be cheap.Is it worth it Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500,000 years. Sounds prettyrare-but if one did fall,it would be the end of the world.“If wedon't take care of these big asteroids,they'll take care of us,”says one scientist.“It's that simple.”The cure,though,might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth?“The world has less to fear fromdoomsday(毁灭性的) rocks than from a great nuclear fleet set against them,” said a New York Times article.21. What does the passage say about asteroids and meteoroidsA) They are heavenly bodies different in composition.B) They are heavenly bodies similar in nature.C) There are more asteroids than meteoroids.D) Asteroids are more mysterious than meteoroids.[答案及分析]:[B]文章第二段第一句明确指出“小行星和划破夜空的流星是性质一样的物质,只是体积大些。

Despit occasional alarms, the country escaped any postwar depression and lived in a state of boom. A n economic survey of the year 1955, atypical year of the 1950’s, may be typical a s illustrating the rapid economic growth of the decade. The national output was value at 10 percent above that of 1954 (1955 output wasestimated 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 milliondollars a day ,or about twenty-five million dollars every hour , all round the clock. Sixty-five million people held jobs andonly a little more than two million wanted jobs but could notfind 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 notlast and would eventually lead to the oppsite-depression.1. What is the best title of the passagea. The Agriculatural Trends of 1950’sb.

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 .

Some researchhas shown that perhaps eighty percent of all human illnessesare related to diet and forty percent of cancer is related tothe 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 otherfood additivies,caused cancer. Yet, these carcinogenicadditives 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 weeat are not all so direct. Farmers often give penicillin tobeef 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.

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 oftensupposed 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 andill 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 whateverform,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. Thecrises 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 serious conditions as high blood pressure and heart disease have established links with 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.are finding less and less time for relaxing themselves because_____.do not know how to enjoy themselvesdo not believe that relaxation is important for healthare travelling fast all the timeare becoming busier with their workto the writer ,the most important character for a good manager is his ________.fearing stressthe art of relaxationsense of responsibilitycontrol over performanceof the follwing statements is turecan find some ways to avoid stressis always harmful to peopleis easy to change the hagit of keeping oneself busy with work. people can withstand different amounts of stressParagraph 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"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:dadbc大学英语四级阅读理解试题40篇之七(含答案)In 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 . 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 settledown 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 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.did some young Americans decide to "drop out" of scoiety during the 1960swere not satisfied with American society.wanted to grow marijuana.wanted to go to the Vietnam War.did not want all people to be equal.did the members of the Hog Farm commune livedome-shaped houseold school husesa farm inTennesseean archology in Arizonagave the people of Drop City the idea to bulid dome-shaped houseSoleriGaskinFullerwas the Twin Oaks commune base onphilosophy of "do your own thing"in the late 1960sideas of psychologistbelief that people must live closely togerher.is an "archology"person who studies archaeologylarge building where people live closely togethercity in A rizonatechnique to contorl people答案:abdcb大学英语四级阅读理解试题40篇之八(含答案)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 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 enviromental difference continued until the twins were in their late teens, when they were giben tesets to measure their intelligence. Mark's . was 125, twenty-five points higher than the average and fully forty points higherthan his identical brother.

"They are real silk," the assistant assured her, trying to tempt her. "Worth double theprice." 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.

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 produceoxygen,should be bred in condition similar to those on 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 rainwill eventually fall and in a few years something like earth will be reproduced on Venus.long run, the most insoluble problem caused by population growth on earth will probably be the lack of ______.Sagan believes that Venus might be colonized from earth because _____might be possible to change its atmosphereatmosphere is the same as the earth'sis a good supply of water on Venusdays on Venus are long enoughVenus there is a lot of ________.dioxidemonoxideare plants that can____.in very hot temperaturesin very cold temperaturesoxygenof the above5.

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 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 ,blackis 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 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_______.don't like to follow otherswould be a member rather than a leaderwould be afraid of following otherswould like to be a leader rather than a followerone enjoys life, one is sure to prefer________.to yellowto orangeto greyto yellow3."They tell us, among other facts,that we don't choose our favourite colours as we grow up."

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 tableThe 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 sowill most Americans. Promptness is important both in England and in America. That is , if a dinner invitation is for 7o'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。

The different shapes of the containers (28)_______ they were used to brew, filter, and store beer. They may be ancient “beer-making tools,”and the earliest (29_______ evidence of beer brewing in China, the researchers reported in the Proceedings of the National Academy of Sciences. To (30)_______ that theory, the team examined the yellowish, dried (31)_______ inside the vessels. The majority of the grains, about 80%, were from cereal crops like barley (大麦),and about 10% were bits of roots, (32)_______lily,which would have made the beer sweeter, the scientistssay. Barley was an unexpected find: the crop was domesticated in Western Eurasia and didn't become a (33)_______food in central China until about 2,000 years ago, according to the researchers. Based on that timing, they indicate barley may have (34)_______ in the region not as food, but as (35)_______material for beer brewing.17.6.2America’s Internet is fester than ever before, but people still complain about their Internet being too slow.New York’s Attorney General’s office (26)_______ an investigation in the fall into whether or not Verizon, Cablevision and Time Warner are delivering broadband that’s as fast as the providers (27)_______ it is. Earlier this month, the office asked for the public’s help to measure their speed results, saying consumers (28)_______ to get the speeds they were promised. “Too many of us may be paying for one thing, and getting another,” the Attorney General said.If the investigation uncovers anything, it wouldn’t be the first time a telecom provider got into (29)_______ over the broadband speeds it promised and delivered customers. Back in June, the Federal Communications Commission fined AT& T $ 100 million over (30)_______ that the carrier secretly reduced wireless speeds after customers consumed a certain amount of (31)_______ .Even when they stay on the right side of the law, Internet providers arouse customers’anger over bandwidth speed and cost. Just this week, an investigation found that media and telecom giant Comcast isthe most (32)_______ provider. Over 10 months, Comcast received nearly 12,000 customer complaints, many (33)_______ to its monthly data cap and overage (超过额度的)charges.Some Americans are getting so (34)_______ with Internet providers they’re just giving up.

Fear not, however, for coffee can stimulate them again. During (26)_______ exercise, our muscles tire as they run out of fuel and build up waste products. Muscle performance can also be affected by a (27)_______ called "central fatigue,” in which an imbalance in the body’s chemical messengers prevents the central nervous system from directing muscle movements (28)_______. It was not known, however, whether central fatigue might also affect motor systems not directly (29) _______ in the exercise itself, such as those that move the eyes. To find out, researchers gave 11 volunteer cyclists a carbohydrate (碳水化合物的)(30)_______ either with a moderate dose of caffeine (咖啡因),which is known to stimulate the central nervous system, or as a placebo (安慰剂)without, during 3 hours of (31)_______ . After exercising, the scientists tested the cyclists with eyetracking cameras to see how well their brains could still (32)_______ their visual system. The team found that exercise reduced the speed of rapid eye movements by about 8%, (33)_______ their ability to capture new visual information. The caffeine, the equivalent of two strong cups of coffee, was (34)_______ to reverse this effect,with some cyclists even displaying (35)_______ eye movement speeds.
