I'm usually fairly skeptical about any research that concludes that people are either happier on unhappier or more or less certain of themselves than they were 50 years ago. While any of there statements might be true, they are practically impossible to prove scientifically. Still, I was struck by a report which concluded that today's children are significantly more anxious than children in the 1950. In fact, the analysis showed, normal children ages 9 to 17 exhibit a higher level of anxiety today than children who were treated for mental illness 50 years ago.Why are America's kids so stressed? The report cites two main causes: increasing physical isolation -- brought on by high divorce rates and less involvement in community, among other things -- and a growing perception that the world is a more dangerous place.Given that we can't turn the clock back, adults can still do plenty to help the next generation cope. At the top of the list is nurturing (培育) a better appreciation of the limits of individualism. No child is an island. Strengthening social ties helps build communities and protect individuals against stress.To help kids build stronger connections with others, you can pull the plug on TVs and computers. Your family will thank you later. They will have more time for face-to-face relationships, and they will get more sleep.Limit the amount of viral (虚拟的) violence your children are exposed to. It's not just radio games and movies; children see a lot of murder and crime on the local news.Keep your expectations for your children reasonable. Many highly successful people never attended Harvard or Yale.Make exercise part of your daily routine. It will help you cope with your own anxieties and provide a good model for your kids. Sometimes anxiety is unavoidable. But it doesn't have to ruin your life.21. The author thinks that the conclusions of any research about people's state of mind are ______.A) surprising C) illogicalB) confusing D)questionable22. What does the author mean when he says, "we can't turn the clock back"(Line 1, Para.3)?A) It's impossible to slow down the pace of change.B) The social reality children are facing cannot be changed.C) Lessons learned from the past should not be forgotten.D) It's impossible to forget the past.23. According to an analysis, compared with normal children today, children treated as mentally ill 50 years ago ______.A) were less isolated physically C) probably suffered less from anxietyB) were probably less self-centered D)were considered less individualistic24. The first and most important thing parents should do to help their children is ______.A) to provide them with a safer environmentB) to lower them expectations for themC) to get them more involved sociallyD) to set a good model for them to follow25. What conclusion can be drawn from the passage?A) Anxiety, though unavoidable, can be coped with.B) Children’s anxiety has been enormously exaggerated.C) Children's anxiety can be eliminated with more parental care.D) Anxiety, it properly controlled, may help children become mature.It is easier to negotiate initial salary requirement because once you are inside, the organizational constraints (约束) influence wage increases. One thing, however, is certain: your chances of getting the raise you feel you deserve are less if you don't at least ask for it. Men tend to ask for more, and they get more, and this holds true with other resources, not just pay increases. Consider Beth's story:I did not get what I wanted when I did not ask for it. We had cubicle(小隔间) offices and window offices.I sat in the cubicles with several male colleagues. One by one they were moved into window offices, while I remained in the cubicles. Several males who were hired after me also went to offices. One in particular told me he was next in line for an office and that it had been part of his negotiations for the job. I guess they thought me content to stay in the cubicles since I did not voice my opinion either way.It would be nice if we all received automatic pay increases equal to our merit, but “nice” isn’t a quality attributed to most organizations. If you feel you deserve a significant raise in pay, you’ll probably have to ask for it.Performance is your best bargaining chip (筹码) when you are seeking a raise. You must be able to demonstrate that you deserve a raise. Timing is also a good bargaining chip. If you can give your boss something he or she needs (a new client or a sizable contract, for example) just before merit pay decisions are being made, you are more likely to get the raise you want. Use information as a bargaining chip too. Find out what you are worth on the open market. What will someone else pay for your services?Go into the negotiations prepared to place your chips on the table at the appropriate time and prepared to use communication style to guide the direction of the interaction.26. According to the passage, before taking a job, a person should ______.A) demonstrate his capability C) ask for as much money as he canB) give his boss a good impression D) ask for the salary he hopes to get27. What can be inferred from Beth’s story?A) Prejudice against women still exists in some organizations.B) If people want what they deserve, they have to ask for it.C) People should not be content with what they have got.D) People should be careful when negotiating for a job.28. We can learn from the passage that ______.A) unfairness exists in salary increasesB) most people are overworked and underpaidC) one should avoid overstating one’s performanceD) most organizations give their staff automatic pay raises29. To get a pay raise, a person should ______.A) advertise himself on the job marketB) persuade his boss to sign a long-term contractC) try to get inside information about the organizationD) do something to impress his boss just before merit pay decisions30. To be successful in negotiations, one must ______.A) meet his boss at the appropriate timeB) arrive at the negotiation table punctuallyC) be good at influencing the outcome of the interactionD) be familiar with what the boss likes and dislikes21.

大学英语四级阅读之十八含答案
大学英语四级阅读之十八含答案Many people believe the glare from snow causes snowblindnenss. Yet, dark glasses or not , they find themselves suffering from headaches and watering eyes,and even snowblindness,when exposed to several hours of “snow light” .The United States Army has now determined that glare from snow does not cause snowblindness in troops in a snow-covered country.Rather, a man’s eyes frequently find nothing to foucs on in a broad expanse of barren snow-covered terrain. So his gaze continually shifts and jumps back and forth over the entire landscape in search of tsomething to look at. Finding nothing, hour after hour, the eyes never sotp searching and the eyeballs become sore and the eye muscles ache. Nature offsets this irritation by producing more and fluid which covers the eyeball. The fluid coversthe eyeball in increasing quantity until vision blurs, then is obsured,and the result is total, even thoughtemporary,snowblindness.Experiments led the Army to a simple method of overcoming this problem. Scouts ahead of a main body of troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape,Even the scouts themselves throw lightweight , dark colored objects ahead on which they too can focus . The men following can then see something.Their gaze is arrested. Their eyes focus on a bush and having found something to see,stop scouring the snow-blanketed lanscape. By focusing their attention on one object at a time,the men can cross the snow without becoming hopelessly snowblind or lost. In this way the problem of crossing a solid white terrain is overcome.1.To prevent headaches, watering eyes and blindness caused by the glare from snow, dark glasses are_____.a.indispensibleefulc.ineffectived.available2.When the eyes are sore tears are produced to ________.a.clear the visionb.remedy snowblindnessc.ease the irritationd.loosen the muscles3.Snowblindness may be avoided by_______.a.concentrating to the solid white terrainb.searching for something to look at insnow-covered terrainc.providing the eyes with something to foucs ond.covering the eyeballs with fluid4.The scouts shake snow from evergreen bushes in order to _______.a.bive the men behind something to seeb.beautify the landscapec.warm themselves in the coldd.prevent the men behind from losing their way5.A suitable title for this passage would be _______.a.snowblindness and how to overcome itb.n atrue’s cure for snowblindnessc.soldiers in the snowd.snow vision18/200答案：CCCAA。

A n economic survey of the year 1955, a typical year of the 1950’s, may betypical as illustrating the rapid economic growth of the decade. The national output was value at 10 percent above that of 1954 (1955 output was estimated at 392 billion dollars). The production of manufacturers was about 40 percent more than it had averaged in the years immediately following World War 2. The country’s business spent about 30billion dollars for new factories and machinery. National income available for spending was almost a third greater than it had been it had been in 1950. Consumers spent about 256 billion dollars; that is about 700 million dollars a day ,or about twenty-five million dollars every hour , all round the clock. Sixty-five million people held jobs and only a little more than two million wanted jobs but could not find them . Only agriculture complained that it was not sharing in the room. To some observers this was an ominous echo of the mid-1920’s . As farmer’s shre of their products declined , marketing costs rose.

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 atthe 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.

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 thelate 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 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 theseprocedures, 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 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 thesame 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 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 andtraveled 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 heis 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大学英语四级阅读理解试题40篇之九（含答案）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大学英语四级阅读理解试题40篇之十（含答案）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 V enus and so create a new world almost as large as earth itself. The difficult is that Venus is much hotter than the earth and there is only a tiny amount of water there. Sagan proposes that algae organisms that can live in extremely hot or cold atmospheres and at the same time produce oxygen,should be bred in condition similar to those on Venus.As soon as this has been done, the algae will be placed in small rockets. Spaceship will then fly to Venus and fire the rockets into the atmosphere .In a fairly short time, the alge will break down the carbon dioxide into oxygen and carbon.When the algae have done theri work, the atmosphere will become cooler,but befor man can set foot on Venus it will be neccessary for the oxygen to produce rain. The surface of the planet will still be too hot for man to land on it but the rain will eventually fall and in a few years something like earth will be reproduced on Venus.1.Inte long run, the most insoluble problem caused by population growth on earth will probably be the lack of ______.a.foodb.oilc.spaced.resources2.Carl Sagan believes that Venus might be colonized from earth because _____a.it might be possible to change its atmosphereb.its atmosphere is the same as the earth'sc.there is a good supply of water on Venusd.the days on Venus are long enough3.On Venus there is a lot of ________.a.waterb.carbon dioxidec.carbon monoxided.oxygen4.Algae are plants that can____.a.live in very hot temperaturesb.live in very cold temperaturesc.manufacture oxygend.all of the above5. Man can land on Venus only when_______.a.the algae have done their workb.the atmosphere becomes coolerc.thereis oxygend.it rains there答案：cabdd大学英语四级阅读理解试题40篇之十一（含答案）What is your favourite colour? Do you like yellow , orange ,red? If you do ,you must be an optimist, a leader, an active person who enjoys life, people and excitement. Do you prefer greys and blues? Then you are probably quiet,shy, and you would rather follow than lead. You tend to be a pessimist. At least, this is what psychologists tell us, and they should know,because they have been seriously studying the meaning of colours preference, as well as the effect that colours have on human beings. They tells us, among other facts,that we do not choose our favourite clour as we grow up----we are born with our preference.If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.Colours do influence our moods----there is no doubt about it .A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand ,black is depressing. A black bridge over the Thames River, near London, used to be the scene of more suicides than any other bridge in the area ----until it was repainter green.The number of suicide attempts immediately fell sharply ;perhaps it would have fallen even more if the bridge had been done in pink or baby blue. Light and bright colours make people not only hppier but more active. It is an established fact that factory workers work better,harder ,and have fewer accidents when their machines are painted orange rather than black or grey.1."You would rather follow than red" means_______.a.you don't like to follow othersb.you would be a member rather than a leaderc.you would be afraid of following othersd.you would like to be a leader rather than a follower2.If one enjoys life, one is sure to prefer________.a.red to yellowb.blue to orangec.red to greyd.blue to yellow3."They tell us, among other facts,that we don't choose our favourite colours as we grow up."。
四级阅读理解练习与参考答案
四级阅读理解练习与参考答案四级阅读理解练习与参考答案：Directions：There are 2 passages in this section.Each passage isfollowed by some questions or unfinished statements.For each ofthem there are four choices marked A.，B.，C.andD..You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 56 to 60 are based on thefollowingpassage.They say that sticks and stones may break your bones，but words will never hurt you.Yet childhood bullying really can damage your long-term health.Gone are the days when bullying was considered an inevitable and ultimately harmless part of growing up—iust last month we learned that childhood bullying can lead to poorer mental health even into middle age.Now William Copeland at Duke University in Durham，North Carolina，and his colleagues have shown that it can have lingering physiological effects too.They tracked 1420 9-year-olds right through their teens.Each child was seen up to nine times during the study and quizzed about bullying.The team then measured levels of C-reactive protein in theirblood.CRP is a marker of inflammation(炎症)linked to higher risk of cardiovascular disease (心血管疾病)and problems like diabetes.“Because we were collecting biological samples throughout，we were able to look at CRP levels in subjects prior to their bullying involvement.”says Copeland.“This really gives us an idea of the changes bullying brings about.”Although CRP levels naturally rise in everyone during adolescence，levels were highest in children who reported being tormented by bullies.Even at the ages of 1 9 and 2 1，children who had once been bullied had CRP levels about 1.4 times higher than peers who were neither perpetrators nor victims.In a cruel twist，the bullies had the lowest levels of all.suggesting they didnt suffer the same health risks. They may even see a benefit from their behavior,though Copeland stresses it doesnt vindicate(辩护)their actions.“The goal would instead be to find other ways to produce this protective effect without it being at someone elses expense，”he says.Andrea Danese at Kings College London has previously shown that maltreatment during childhood can lead to higll levels of inflammation in adult life.“This new study is a helpful addition in showing that these effects extend to another important childhood stressor,”he says.He suggests that care workers could monitor levels of CRP in children having psychotherapy to see if it is helping to soothe the stress of being bullied.56.What do you know about CRP?A.It is a symbol of the inflammation.B.It is a symbol of cardiovascular.C. It relates directly to diabetes.D.It is a symbol of physiological effects caused by bullying.57.What does Copeland mean by saying“prior to their bullying involvement”(Line 2，Para.4)?A.Before the children bullied others.B.Before the children were bullied.C.In preference to the childrens bullying behavior.D.In preference to the childrens being bullied.58.What can be learned from paragraph 5?A. The levels of CRP of the children being bullied are much higher than their peers.B. CRP levels naturally rise along with the increase of age.C.The bullies are not blamed for the health risks of the bullied.D. Copeland intends to defend the benefit of the bulliesactions.59.What does Andrea Danese suggest about childhood maltreatment?A. It has nothing to do with inflammation in adult life.B.Copelands study shows nothing related to it.C.CRP is the marker of childhood abuse.D. It has an influence on Childrens CRP levels.60.What is the main idea of this passage?A.Bullying is harmless to childrens growth.B.CRP levels reflect the risks of poorer health.C.Bullying does harm to a person all through his life.D.Children once bullied have higher CRP levels than peers who are not. 四级阅读理解练习与参考答案：Questions 61 to65 are based on thefollowingpassage.Heres a case study for would-be MBAs to consider：the success of H Mart.an international supermarket chain based in New Jersey(the“H”in H Mart stands for Han Ah Reum.which means“one arm full of groceries”in Korean).Tlle first H Mart opened in Queens，New York in 1982，as a corner shop.Now there are stores in 11 states，Canada and Britain.A new one recently opened in Cambridge.Massachusetts，an affluent city outside Boston.The future looks bright for Asian supermarkets like H Mart.Eamings of Asian-American households outpace the American average.Their spending exceeds all other groups，too，according to Geoscape，a consultancy.And they spend more of their money on groceries than the average America household.But Asian delicacies can be hard to come by：few Americans are likely to see durian or bamboo shoots in their local shop.Some specialty ingredients are only to be found at a premium(高价)in up-market grocery stores，or miles away,in ethnic markets in older Asian neighborhpods.Americans have developed greater appetite for cooking and eating Asian foods，t00.In 2012 non.restaurant sales of Asian foods topped $1.5billion，according to Mintel Group.a market.research firm.Though Latin foods are a bigger market，the popularity of Asian foods is growing faster.Once strange.seeming imports like seaweed and sashimi are now fashionable eats.Though the rate of growth is expected to fall，sales are likely to keep rising.Yet most Asian grocers have not made efforts to reach new customers，says Jeffrey Cohen，an analyst at IBIS World,an industries watcher.Many shops are located in minority enclaves，and do little to market themselves to other Americans.Cramped car parks and dingy interiors fend off customers used to the bright fluorescence(荧光)of mainstream supermarkets.Ingredients labeled with poorly-translated English Can leave shoppers bamed.A few Asian grocery chains have caught on，opening stores in more diverse suburbs，paying attention to cosmetic niceties(细节)and marketing more widely.Other than H Mart，there are Califomian chains such as 99 Ranch Market and Shun Fat Supermarket，which have been expanding to the American southwest.The former was even featured in a humorous YouTube music vide —“Asians Eat Weird Things”—which has attracted more than 900，000 hits.Those weird things may not seem so weird after all.61.What makes the future ofAsian supermarkets so bright?A.High income and spending ofAsian-AmeriCalls.B.

大学英语四级阅读之十九含答案
大学英语四级阅读之十九含答案Water problems in the future will become nore intense and more complex. Our increasing population will tremendously increase urban wastes,primarily sewage. On the other hand, increasing demands for water will decease substantialy the amount of water available for diluting wastes. Rapidly expanding industries which involve more and more complex chemical processes will produce large volumes of liquid wastes, and many of these will contain chemicals which are noxious. To feed our rapidly expanding population, agriculture will have to be intensified. This will involveever-increasingquantities of agricultural chemicals, From this , it is apparent that drastic steps must be taken immediately to develop corrective measures for the pollution problem.There are two ways by which this pollution problem can be dwindled. The first relates to the treatment of wastes to decrease their pollution hazard.This involves the processing of solid wastes “prior to “ disposal and the treatment of liquid was tes, or efflunets,to permit the reuse of the water or minimize pollution upon final disposal.A second approach is to develop an economic use for all or a part of the wastes. Farm manure is spread in fields as a nutrient or organic supplement . Effluents from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained. Efflunets from other processing plants may also be used as a supplemental source of water. Many industries, such as meat and poultry processing plants, are currently converting former waste products into marketable byproducts. Other industries are potential eonomic uses for waste products.1.The purpose of this passage is ______.a.to alert the reader to the dwindling water supplyb.to explain industrial uses of waterc.to acquaint the reader with water pollution problemsd.to demostrate various measures to solve thepollution problem2.Which of the following points is NOT INCLUDED in the passage?a.In dustrial development incudes the simplification of complex chemical processes.b.Diluting wastes needs certain amount of waterc.Demands for water will go up along with the expanding populationd.Intensive cultivation of land requires more and more chemicals3.The reader can conclued that________.a.countries of the world will work together on polution problemsb.byproducts from wastes lead to a more prosperous marketplacec.science is making great progress on increasing water suppliesd.some industries are now ,aking economic use of wastes4.The author gives substance to the passage through the use of _______.a.interviews with authorities in the field ofwater controlsb.opinions and personal observationsc.definitions which clarify important termsd.strong arguments and persuasions5.The words “prior to “(para.2) probably mean______.a.afterb.duringc.befored.beyond19/200答案:cadbc。
