大学英语四级阅读练习带答案
大学英语四级阅读练习带答案大学英语四级阅读练习带答案The decline in moral standardswhich has long concerned social analystshas at last captured the attention of average Americans. And Jean Bethke Elshtain, for one, is glad.The fact the ordinary citizens are now starting to think seriously about the nations moral climate, says this ethics (伦理学) professor at the University of Chicago, is reason to hope that new ideas will come forward to improve it.But the challenge is not to be underestimated. Materialism and individualism in American society are the biggest obstacles. The thought that Im in it for me has become deeply rooted in the national consciousness, Ms. Elshtain says.Some of this can be attributed to the disintegration of traditional communities, in which neighbors looked out for one another, she says. With todays greater mobility and with so many couples working, those bonds have been weakened, replaced by a greater emphasis on self.In a 1996 poll of Americans, loss of morality topped the list of the biggest problems facing the U.S. and Elshtain says the public is correct to sense that: Data show that Americans are struggling with problems unheard of in the 1950s, such as classroom violence and a high rate of births to unmarried mothers.The desire for a higher moral standard is not a lament (挽歌) for some nonexistent golden age, Elshtain says, nor is it a wishful (一厢情愿的) longing for a time that denied opportunities to women and minorities. Most people, in fact, favor the lessening of prejudice.Moral decline will not be reversed until people find ways to counter the materialism in society, she says. Slowly, you recognize that the things that matter are those that cant be bought.36. Professor Elshtain is pleased to see that Americans ________.(A) have adapted to a new set of moral standards(B) are longing for the return of the good old days(C) have realized the importance of material things(D) are awakening to the lowering of their moral standards37. The moral decline of American society is caused manly by ________.(A) its growing wealth(B) the self-centeredness of individuals(C) underestimating the impact of social changes(D) the prejudice against women and minorities38. Which of the following characterizes the traditional communities(A) Great mobility.(B) Concern for ones neighbors.(C) Emphasis on individual effort.(D) Ever-weakening social bonds.39. In the 1950s, classroom violence ________.(A) was something unheard of(B) was by no means a rare occurrence(C) attracted a lot of pubic attention(D) began to appear in analysts data40. According to Elshtain, the current moral decline may be reversed ________.(A) if people can return to the golden age(B) when women and mean enjoy equal rights(C) when people rid themselves of prejudice(D) if less emphasis is laid on material things36. D 37. B 38. B 39.A 40. DIn the 1960s, medical researchers Thomas Holmes and Richard Rahe developed a checklist of stressful events. They appreciated the tricky point that any major change can be stressful. Negative events like serious illness of a family member were high on the list, but so were some positive life-changing events, like marriage. When you take the Holmes-Rahe test you must remember that the score does not reflect how you deal with stressitonly shows how much you have to deal with. And we now know that the way you handle these events dramatically affects your chances of staying healthy.By the early 1970s, hundreds of similar studies had followed Holmes and Rahe. And millions of Americans who work and live under stress worried over the reports. Somehow, the research got boiled down to a memorable message. Womens magazines ran headlines like Stress causes illness! If you want to stay physically and mentally healthy, the articles said, avoid stressful events.But such simplistic advice is impossible to follow. Even if stressful events are dangerous, manylike the death of a loved oneare impossible to avoid. Moreover, any warning to avoid all stressful events is a prescription (处方) for staying away from opportunities as well as trouble. Since any change can be stressful, a person who wanted to be completely free of stress would never marry, have a child, take a new job or move.The notion that all stress makes you sick also ignores a lot of what we know about people. It assumes were all vulnerable (脆弱的) and passive in the face of adversity (逆境). But what about human initiative and creativity Many come through periods of stress with more physical and mental vigor than they had before. We also know that a long time without change or challenge can lead to boredom, and physical and metal strain.21. The result of Holmes-Rahes medical research tells us ________.(A) the way you handle major events may cause stress(B) what should be done to avoid stress(C) what kind of event would cause stress(D) how to cope with sudden changes in life22. The studies on stress in the early 1970s led to ________.(A) widespread concern over its harmful effects(B) great panic over the mental disorder it could cause(C) an intensive research into stress-related illnesses(D) popular avoidance of stressful jobs23. The score of the Holmes-Rahe test shows ________.(A) how much pressure you are under(B) how positive events can change your life(C) how stressful a major event can be(D) how you can deal with life-changing events24. Why is such simplistic advice (Line 1, Para. 3) impossible to follow(A) No one can stay on the same job for long.(B) No prescription is effective in relieving stress.(C) People have to get married someday.(D) You could be missing opportunities as well.25. According to the passage people who have experienced ups and downs may become ____.(A) nervous when faced with difficulties(B) physically and mentally strained(C) more capable of coping with adversity(D) indifferent toward what happens to them21. C 22. A 23. A 24.D 25.C。
英语四级考试阅读辅导练习题及答案
英语四级考试阅读辅导练习题及答案英语四级考试阅读辅导练习题及答案2017在当今这个学习英语风潮盛行的社会，英语似乎已经成为了我们生活中不可或缺的一部分，下面是小编为大家搜索整理的英语四级辅导练习，希望能给大家带来帮助!The human brain contains 10 thousand million cells and each of these may have a thousand connections. Suchenormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with human -like ability, but now that we have grown used to moving forward at such a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps, we will be able to assemble a machine as complex as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading in the right software (软件)or by altering the architecture but that too will happen.I think it certain that in decades, not centuries, machines of silicon (硅)will arise first to rival and then exceed their human ancestors. Once they exceed us they will be capable of their own design. In a real sense they will be able to reproduce themselves. Silicon will have ended carbon’s long control. And we will no longer be able to claim ourselves to be the finest intelligence in the known universe.As the intelligence of robots increases to match that of humans and as their cost declines through economies of scale we may use them to expand our frontiers, first on earth through their ability to withstand environments, harmful to ourselves. Thus, deserts may bloom and the ocean beds be mined. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the construction of avast, man-created world in space, home to thousands or millions of people, will be within our power.练习题：Choose correct answers to the question:1.1.In what way can we make a machine intelligent?A. By making it work in such environments as deserts, oceans or space.B. By working hard for 10 or 20 years.C. By either properly programming it or changing its structure.D. By reproducing it.2.What does the writer think about machines with human-like ability?A. He believes they will be useful to human beings.B. He believes that they will control us in the future.C. He is not quite sure in what way they may influence us.D. He doesn’t consider the construction of suc h machines possible.3.The word “carbon” (Line 4, Para.2) stands for _________.A. intelligent robotsB. a chemical elementC. an organic substanceD. human beings4.A robot can be used to expand our frontiers when _______.A. its intelligence and cost are beyond questionB. it is able to bear the rough environmentC. it is made as complex as the human brainD. its architecture is different from that of the present ones5.It can be inferred from the passage that _______.A. after the installation of a great number of cells andconnections, robots will be capable of self-reproductionB. with the rapid development of technology, people have come to realize the possibility of making a machine with human-like abilityC. once we make a machine as complex as the human brain, it will posses intelligenceD. robots will have control of the vast, man-made world in space参考答案1.[C] 事实细节题。
大学英语四级考试阅读练习和答案
大学英语四级考试阅读练习和答案The political background of the atomic scientists work was the determination to defeat the Nazis. It was heldI think rightlythat a Nazi victory would be an appalling (令人惊骇的 ) disaster. It was also held, in Western countries, that German scientists must be well advanced towards making an A-bomb, and that if they succeeded before the West did they would probably win the war. When the war was over, it was discovered, to the complete astonishment of both American and British Scientists, that the Germans were nowhere near success, and, as everybody knows, the Germans were defeated before any nuclear weapons had been made. But I do not think that nuclear scientists of the West can be blamed for thinking the work urgent and necessary. Even Einstein favored it.When, however, the German war was finished thegreat majority of those scientists who hadcollaborated toward making the A-bomb considered thatit should not be used against the Japanese, who were already on the verge of defeat and, in any case, did not constitute such a threat to the world as Hitler. Many of them made urgent representations to the American government advocating that, instead of using the bomb as a weapon of war, they should, after a public announcement, explode it in a desert, and that future control of nuclear energy should be placed in the hands of an international authority. Seven of the most famous of nuclear scientists drew up what is known as the Franck Report which they presented to the Secretary of War in June 1945. This is a very admirable and far-seeing document, and if it had won the assent of the politicians, none of our subsequent terrors would have arisen.21. We may infer that the writers attitude towards the A-bomb is that______.A. it is absolutely necessaryB. it is a terrible threat to the whole of mankindC. it played a vital part in defeating the JapaneseD. it was a wonderful invention22. The American and British scientists were astonished at the end of the Second World War against Germany because______.A. the Germans had been defeated without the useof nuclear weaponsB. the Western countries had won before they had invented nuclear weaponsC. they thought the Germans would probably win the warD. the Germans had made little progress in developing nuclear weapons23. According to the writer, most scientists who had helped in making the A-bomb considered that it should not be used against the Japanese because______.A. it was such a dangerous weaponB. its use against the Japanese was unnecessaryC. it was a very inhumane weaponD. the German war was finished24. The passage implies, but does not directly say, that the nuclear scientists______.A. might not have agreed to develop the bomb if there had been no Nazi threatB. would have developed the bomb even without the Nazi threatC. would have made the bomb, under peace-time conditions, but only for the use of an international authorityD. developed the bomb because Einstein thought it urgent and necessary25. The main point in the second paragraphis______.A. that nuclear weapons proved unnecessaryB. that the Franck Report, which recommended that the bomb should be placed in the hands of an international authority, was rejectedC. that many scientists tried, unsuccessfully, to persuade the politicians to abandon nuclear bombs, and place nuclear energy in the hands of an international authorityD. both A and C21. B 22. D 23. B 24. A 25. CFriends play an important part in our lives, and although we may take the friendship for granted, we often dont clearly understand how we make friends. While we get on well with a number of people, we are usually friends with only a very few, for example, the average among students is about 6 per person. In all the cases of friendly relationships, two people like one another and enjoy being together, but beyond that, the degree of intimacy between them and the reasonsfor their shared interest vary enormously. As we get to know people we take into account things like age, race, economic condition, social position, and intelligence. Although these factors are not of prime importance, it is more difficult to get on with people when there is a marked difference in age and background.Some friendly relationships can be kept on argument and discussion, but it is usual for close friends to have similar ideas and beliefs, to have attitudes and interests in commonthey often talk about being on the same wavelength. It generally takes timeto reach this point. And the more intimately involved people become, the more they rely on one another. People want to do friends favors and hate to break a promise. Equally, friends have to learn to put up with annoying habits and to tolerate differences of opinion.In contrast with marriage, there are no friendship ceremonies to strengthen the association between two people. But the supporting and understanding of each other that results from shared experiences and emotions does seem to create a powerful bond, whichcan overcome differences in background, and break down barriers of age, class or race.26. According to the author, _______.A. all those who get on well with each other are friendsB. friends are closer than people who just get on well with each otherC. everyone understands clearly how to makefriendsD. every student has 6 friends27. When we make friends, we consider such things as age, race, and background, because _______.A. it is not easy to have a friendly relationship with people when there is a marked difference in age and backgroundB. the degree of friendship between two people and the reasons for their shared interest can vary greatlyC. friends need to know all these thingsD. these are the most important factors to make friends28. In Paragraph 2, being on the same wavelength means_______.A. using the same frequency while talkingB. keeping the same friendly relationship as other people doC. having similar ideas, beliefs, attitudes and interestsD. having the same background29. Which of the following is not implied in the passageA. Even friends may have differences of opinion.B. Friends never argue with each other.C. It generally takes time for people to become close friends.D. Someones habits may annoy his friends.30. To strengthen friendly relationship,people_______.A. must hold friendship ceremoniesB. have to eliminate differences in backgroundC. should make friends with those who are of the same age and of the same raceD. should support and understand each other through shared experiences and emotions26.

英语四级阅读理解精选练习及答案
英语四级阅读理解精选练习及答案英语四级阅读理解练习一：Personality is , to large extent, inherent --A-type parents usually bring about A-type offspring. But the environment must also have a profound effect, since if competition is improtant to the parents, it is likely to become a major factor lives of their children.One place where children soak up A characteristics is school, which is, by its very nature, a highly competitive institution. Too many schools adopt the "win at all costs" moral standard and measure their success by sporting achievements. The current passion for making children compete against their classmates or against the clock produces a two-layer system, in which competitive A types seem in some way better than their B-type fellows. Being too keen to win can have dangerous consequences:remember that Pheidippides ,the first marathon runner, dropped dead seconds after saying:"Rejoice, we conquer!".By far the worst form of competition in school is the disproportionate emphasis on examinations . It is a rare school that allows pupils to concentrate on those things they do well.The merits of competition by examination are somewhat questionable, but competition in the certain knowledge of failure is positively harmful.Obviously, it is neither practical nor desirable that all A youngsters change into Bs. The would needs types, and schools have an important dutyto try to fit a childs personality to his possible future employment. It is top management.1. According to the author, what factors contribute to the building of personality?A. inheritanceb. inheritance, competition and environmentc. competitiond. environment2.Which of the following statements is not true according to the author of the passage?A.

Schools abolish all forms of examinations.答案：bdccb英语四级阅读理解练习二：Nearly everybody buys a used car sooner or later, as a primary vehicle (首要的交通工具) or as a second car. Indeed(当然), three out of four sales today are used cars, and theyre not cheap junkers (废物)either—the average price now is $ 5500, about half what a new car costs. Make the wrong selection and a major investment (投资)can be lost the moment you drive off the lot.There is far less chance of this happening to you if you know: when to buy, where to buy, how to examine (仔细检查) the car, how to conduct (进行) your own road test, and how to bargain over (讲价)the price.When to buyShop during the day. Lighting makes cars gleam (V 闪光)like jewels (宝石)at night. In daylight they look dull (黯淡的), but realistic.Dont shop in the rain. It can mask(掩盖) liquids (液体) that might be leaking (泄漏). If possible, shop in the winter when supplies are high and demand (需求)is low.Where to buyShop the suburbs. In more affluent (富有的)neighborhoods cars are more likely to have been well cared for.A private owner normally sells a car for less than a dealer(商人) does, but almost always "as is," with no guarantee(质量保证). Thats an acceptable risk if what youre looking for is a cheap second car to "drive to the station. "Even though a used-car dealer generally charges more, you can often get some type of limited guarantee. This is often a 50-50 plan, in which you each pay half on repairs for a period (一段时间)that may range from 30 days to a year. Ask the dealer about the availability of an optional(可选择的) service policy.Used-car dealers often claim (声称)to have gone over (仔细查看)the car, and many have. But remember that small dealers often buy cars that are auctioned (拍卖 ) because nobody else wants them.Some experts feel that a new-car dealer is the best place to buy a secondhand car, especially if youre laying out a large sum (一笔金钱) for a late model. Some of these dealers offer extensive (广阔的)guarantees, such as one on the "drive train," which covers any problems with engine (发动机), transmission(变速器) ， drive shaft and differential (差速器 ). Expect to pay for this, as well as for the markup (标高的价格). But if you shop soon after the new models have arrived, when a dealer has a lot of trade-ins tying up his profits, he might deal. The visual examination (视觉上的检查)Youve found your dream car, and can hardly wait to get in and roar away. Wait.First, look for any flaws (瑕疵)or ripples(划痕) in the body that might indicate a past accident (暗示曾经出过事故). To see if a car has been repainted(重新漆过), look under the rubber seals around the door or under the chrome trim. Repainting may mask deep flaws (重新上漆可能隐藏深层的瑕疵).Check the odometer (计程器) for total mileage (英里数), and then compare that figure (数字)with any stickers still attached to door posts. Its illegal to change odometer readings, but it happens. If there are no stickers, be a little suspicious. Check pedals and controls: wear on these parts should agree with the mileage. If they are brand new, be suspicious. If they are worn out, beware.Check that the doors, hood and trunk all open smoothly and close with solid sound. Sight along the sides of the car from 30 feet away to be sure that the rear and front wheels line up.Look under the car for fluid leaks. Except for condensation from a working air conditioner on a hot day, no car should ever drip anything, any time.Now sit in the drivers seat and try the controls. The car should fit you—it should be comfortable. Check seat adjustment, door locks, window-raising mechanisms, horn, lights, directional signals, radio—all accessories.Start the engine. It should turn over quickly and then settle down to a rather fast idle. Give the engine a moment or two before you press the accelerator a bit. Watch for smoke from the rear. Blue smoke mightmean a complete engine overhaul (大修) , black a maladjusted carburetor (化油器). 2White smoke can be. Ignored if the engine is cold, but once it is warmed up, white smoke can mean a leaking head gasket (垫圈) : expensive. Reject this car.After the engine has warmed, shut it off, and then go wipe your finger inside the tailpipe (making sure its not too hot). The residue should be whitish-gay. If you get a black, oily mark, refuse the car—its probably an oil burner.Restart the engine and check the oil in an automatic transmission. It should be clean and clear, with no burned odor. The test drive The salesman may try to convince you that a short drive around the block is enough. Wrong. Make it clear that you plan to road test the car, and if he isnt happy with this look elsewhere.The test route you have mapped out should include dry city streets, a freeway, a hill, a bumpy road and an empty parking lot. All gauges(计量器) should read steady and normal throughout the test, especially oil pressure and engine heat. If not, dont buy the car.Drive to a traffic-free city street on your predetermined route and then accelerate smoothly to about 35 miles per hour. The automatic transmission should shift without jerking and with no noise.Slow to about 7 m. p. h. by gently applying the brakes. There should be no noise, no sharp sound or grinding. The car should slow in a straight line, with no pulling to the right or left.Pick up speed to about 15; then making certain nobody is behind you, hit the brakes hard! The car should come to an immediate stop without making noise or swerving.In an empty, level parking lot, brake to a complete stop. Shift into reverse and back up at about 4 m. p. h. , brake to a halt, shift into forward, etc. Do this four or five times to test the transmission. All shifting should be smooth, with no noise or hesitation.Accelerate up a hill to about 40 m. p. h. The car should not labor. If it does, you could have a rotten transmission. Go back down the hill. Stop halfway, shift into neutral and set the parking brake. The car should remain stationary when you take your foot off the brake pedal.Drive the car over the bumpy road, up a hill, and on the highway. Rarely will a car be perfect. However by now you should have a pretty good idea what needs to be done. How to bargainUse what youve learned from the visual exam, test drive and outside mechanic to get the price down. Have a maximum figure in mind, based on your inspection and on current prices from a used-car guide. Start your bidding lower than that. When you have nearly arrived at a price, get the seller to throw in certain repairs. It may be cheaper for him than further price cuts.1. Following the instructions here will help you make a good selection when buying a used car.2. Winter is a good time for purchasing a car because there is little rain in winter.3. You are more likely to pay less to a private owner for a car of poor quality.4. Refuse the car if you find any signs of a past accident in the visual examination.5. Dont buy the car if there is white smoke coming out of the rear because it is probably an oil burner.6. At certain speeds in the tests, a good car should not make any noise when the driver brakes either hard or gently.7. If you are patient and careful enough, you will certainly find a perfect used car.8. The last step before you make a decision to buy a car is______.9. Besides all gauges, the two very important systems mainly examined in the test drive are______.10. According to some experts, the best place to buy a second-hand car is______.答案：1. Y 2. N 3. Y 4. NG 5. N 6. Y 7. N 8. to bargain over the price 9. brake and transmission 10. a new-car dealer。
大学英语四级阅读之十五含答案
大学英语四级阅读之十五含答案Newdays,a standard for measuring power has changed.These changes foretell a new standard for measuring power.No longer will a nation’s political influence be based solely on the strength of its military forces. Of course, military effectiveness will remain a primary primary measure of power.But political influence is also closely tied to industrial competitiveness. It’s often said that without its military the Soviet Union would really be a third-world nation. The new standard of opwer and influence that is evolving now places more emphasis on the ability of a country to compete effectively in the economic markets of the world.America must recognize this new course of events. Our success in shaping world events over the past 40 years has been the direct result of our ability to adapt technology and to take advantage of the capabilities of our people for the purpose of maintaining peace. Ourindustrial prowess over most of this period was unchallenged. It is ironic that it is just this prowess that has enabled other countries to prosper and in turn to threaten our industrial leadership.The competitiveness of America’s industrial base is an issue bigger than the Department of Defense and is going to require the efforts of the major institutional forces in oursociety-government,industry,and education. That is not to say that the Defense Department will not be a strong force in the process because we will. But we simply cannot be, nor should we be, looked upon by others as the savior of American industry.1. Now a nation’s political influence depends on _________.a. the strength of its military forcesb. its ability to compete in industryc. economic marketsd. both a and b2. The Soviet Union was not listed as athird-world nation just because of _________.a. its powerful military forcesb. its vast landc. its industrial competitivenessd. its contributions to world peace3. The author indicates that ______ is threatening American political power.a. other countriesb. the declining U.S. industrial basec. a new standard for measuring powerd. less advanced technology4.

The purpose of writing this article is__________.a. to draw the readers’ attention to a new standard for measuring powerb. to demonstrate American political influence in the worldc. to emphasize that efforts must be made to strengthen the declining U.S. industrial based. to show American industrial prowess15/200答案：dabdc。

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 in1987was greater than that of1985b.the number of women professors in the University in1987was smaller than that of1985c.the number of women professors was the same as that of1985d.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大学英语四级阅读理解试题40篇之四（含答案）Today,as in every other day of the year,more than3000U.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 these3000about23will be murdered,30 will die in traffic accidents,and nearly750will 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 late1970s,when daily smoking among high school seniors reached30precent,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 late1970s,smoking among male high school seniors exceeded that among female by nearly10percent.The statistic is reversing.Third,several recent studies have indicate high school dropouts have excessively high smoking rates,as much as75percent.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.In1945,about35years 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 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 Paragraph3,"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 the1960s,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 in1969.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 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.In1972,Italian architect Paolo Soleri began to build Arcosanti,a utopian city Arizsona where2500people 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 the1960s?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

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.was125,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 thesame 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,"Y our 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

resources left to sustain life on the planet.By the middle of the21st 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 ofsupporting 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 V enus.As soon as this has been done,the algae will be placed in smallrockets.Spaceship will then fly to V enus 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 V enus 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 V enus.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 V enus 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 V enusd.the days on V enus are long enough3.On V enus 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 V enus 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."Y ou would rather follow than red"means_______.a.you don't like to follow othersb.you would be a member rather than a leaderc.you would be afraid of following othersd.you would like to be a leader rather than a follower2.If one enjoys life,one is sure to prefer________.a.red to yellowb.blue to orangec.red to greyd.blue to yellow3."They tell us,among other facts,that we don't choose our favourite colours as we grow up.""Among other facts" means______.a.besides other factsb.in regard to other factsc.not considering other factsd.according to other facts4.Which of the following is facts?a.People's preference of one colour to another is instinctb.People's preference of one colour to another is acquired as they grow up.c.More people happen to love brown because they saw something brown when they were bornd.Colours have little influence on our moods5.Those who committed suicide preferred the bridge over the Thames River near london to others because of_______.。

以下是店铺为大家搜索整理的2017年英语四级阅读考试练习及答案解析，希望能给大家带来帮助!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 they fixate. 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, a tenth 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 thi ng to improve a person’s ability to see words and quite another thing to improve his ability to read a text efficiently. Reading requires the ability tounderstand 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 text.Q:1. The time of the recognition span can be affected by the following facts except ________ .A. one’s familiarity with the textB. one’s purpose in readingC. the length of a group of wordsD. lighting and tiredness2. The author may believe that reading ______.A. requires a reader to take in more words at each fixationB. requires a reader to see words more quicklyC. demands an deeply-participating mindD. demands more mind than eyes3 What does the author mean by saying “but it’s one thing to improve a person’s ability to see words and quite another thing to im prove his ability to read a text efficiently.” in the second parapraph?A. The ability to see words is not needed when an efficient reading is conducted.B. The reading exercises mentioned can’t help to improve both the ability to see and to comprehend words.C. The reading exercises mentioned can’t help to improve an efficient reading.D. The reading exercises mentioned has done a great job to improve one’s ability to see words.4. Which of the following is NOT true?A. The visual span is a word or a group of words we see each time.B. Many experts began to question the efficiency of eye training.C. The emphasis on the purely visual aspects is misleading.D.The eye training will help readers in reading a continuous text.5. The tune of the author in writing this article is ________A criticalB neutralC prssimisticD optimistic【答案及详解】答案：CCCDA1 C。

大学生英语四级阅读模拟练习题带答案大学生英语四级阅读模拟练习题带答案2017年英语考试备考工作正在进行中，备考复习资料必不可少，下面是小编为大家搜索整理的英语四级辅导练习，希望能给大家带来帮助!As regards social conventions, we must say a word about the well-known English class system. 『This is an embarrassing subject for English people, and one they tend to be ashamed of, though during the present century class-consciousness has grown less and less, and the class system less rigid.』① But it still exists below the surface. Broadly speaking, it means there are two classes, the “middle class” and the “working class”. (We shall ignore for a moment the old “upper class”, including the hereditary aristocracy, since it is extremely small in numbers; but some of its members have the right to sit in the House of Lords, and some newspapers take a surprising interest in their private life.) The middle class consists chiefly of well-to-do businessmen and professional people of all kinds. The working class consists chiefly of manual and unskilled workers.The most obvious difference between them is in their accent. Middle-class people use slightly varying kinds of “received pronunciation” which is the kind of E nglish spoken by BBC announcers and taught to overseas pupils. Typical working-class people speak in many different local accents which are generally felt to be rather ugly and uneducated. One of the biggest barriers of social equality in England is the two-class education system. To have been to a so-called “public school” immediately marks you out as one of the middle class. The middle classes tend to live a more formal life than working-class people, and are usuallymore cultured. Their midday meal is “lunch” and they have a rather formal evening meal called “dinner”, whereas the working man‘s dinner, if his working hours permit, is at midday, and his smaller, late-evening meal is called supper.As we have said, however, the class system is much less rigid than it was, and for a long time it has been government policy to reduce class distinctions. 『Working-class students very commonly receive a university education and enter the professions, and working-class incomes have grown so much recently that the distinctions between the two classes are becoming less and less clear. 』②However, regardless of one‘s social status, certain standards of politeness are expected of everybody, and a well-bred person is polite to everyone he meets, and treats a labourer with the same respect he gives an important businessman. Servility inspires both embarrassment and dislike. Even the word “sir”, except in school and in certain occupations (e.g. commerce, the army etc.) sounds too servile to be commonly used.1. The middle class mainly refers to people ______.A. who were born as aristocratB. who have the right to sit in the House of LordsC. who speak in many different local accentsD. who are prosperous businessmen or who work in some professions2. The most obvious difference between the working class and the middle class in English is their ______.A. dressB. workC. accentD. meal3. Why isn‘t the word “sir” commonly used in Britain?A. Because it sounds too servile and is likely to cause embarrassment.B. Because it can only be used in some certain occupations.C. Because it is an impolite word.D. Because it shows that the speaker is not a well-bred person.4. The “upper class” in England today ______.A. are extremely small in number so that media pays no attention to themB. still uses old words like “Sir” in their everyday lifeC. includes the hereditary aristocracyD. refers only to the royal family5. Which of the following is not true about the English class system?A. It is an embarrassing subject for English people.B. Working-class students cannot receive a university education.C.

阅读材料：Americans are pound of their variety and individuality, yet they love and respect few things more than a uniform, whether it is the uniform of an elevator operator or the uniform of a five-star general. Why are uniforms so popular in the United States?Among the arguments for uniforms, one of the first is that in the eyes of most people they look more professional than civilian (百姓的) clothes. People have become conditioned to expect superior quality from a man who wears a uniform. The television repairman who wears uniform tends to inspire more trust than one who appears in civilian clothes. Faith in the skill of a garage mechanic is increased by a uniform. What easier way is there for a nurse, a policeman, a barber, or a waiter to lose professional identity (身份) than to step out of uniform?Uniforms also have many practical benefits. They save on other clothes. They save on laundry bills. They are tax-deductible (可减税的). They are often more comfortable and more durable than civilian clothes.Primary among the arguments against uniforms is their lack of variety and the consequent loss of individuality experienced by people who must wear them. Though there are many types of uniforms, the wearer of any particular type is generally stuck with it, without change, until retirement. When people look alike, they tend to think, speak, and act similarly, on the job at least.Uniforms also give rise to some practical problems. Though they are long-lasting, often their initial expense is greater than the cost of civilian clothes. Some uniforms are also expensive to maintain, requiring professional dry cleaning rather than the home laundering possible with many types of civilian clothes.配套练习：1. It is surprising that Americans who worship variety and individuality ________.A) still judge a man by his clothesB) hold the uniform in such high regardC) enjoy having a professional identityD) will respect an elevator operator as much as a general in uniform2. People are accustomed to think that a man in uniform ________.A) suggests quality workB) discards his social identityC) appears to be more practicalD) looks superior to a person in civilian clothes3. The chief function of a uniform is to ________.A) provide practical benefits to the wearerB) make the wearer catch the pubic eyeC) inspire the wearer’s confidence in himselfD) provide the wearer with a professional identity4. According to the passage, people wearing uniforms ________.A) are usually helpfulB) have little or no individual freedomC) tend to lose their individualityD) enjoy greater popularity5. The best title for this passage would be ________.A) Uniforms and SocietyB) The Importance of Wearing a UniformC) Practical Benefits of Wearing a UniformD) Advantages and Disadvantages of Uniforms。

Adam Smith, writing in the 1770s, was the first person to see the importance of the division of labor and to explain part of itsadvantages. He gives as an example the process by which pins were made in England."One man draws out the wire, another strengthens it, a third cuts it, a fourth points it, a fifth grinds it at the top to prepare it to receive the head. To put it on is a separate operation, to polish the pins is another. It is even a trade by itself to put them into the paper. And the important business of making pins is, in this manner, divided into about eighteen distinct operations, which in some factories are all performed by different people, though in others the same man will sometimes perform two or three of them. "Ten men, Smith said, in this way, turned out twelve pounds of pins a day or about 4800 pins apiece. But if all of them had worked separately and independently without division of labor, theycertainly could not each of them have made twenty pins in a day and perhaps not even one.There can be no doubt that division of labor, provided that it is not taken too far, is an efficient way of organizing work. Fewer people can make more pins. Adam Smith saw this but he also took it for granted that division of labor is in itself responsible for economic growth and development and that it accounts for the difference between expanding economies and those that stand still. But division of labor adds nothing new; it only enables people to produce more of what they already have.21. According to the passage, Adam Smith was the first person to_______.A. take advantage of the division of laborB. introduce the division of labor into EnglandC. understand the effects of the division of laborD. explain the causes of the division of labor22. Adam Smith saw that the division of labor_______.A. enabled each worker to make pins more quickly and more cheaplyB. increased the possible output per workerC. increased the number of people employed in factoriesD. improved the quality of pins produced23. Adam Smith mentioned the number 4800 in order to_______.A. show the advantages of the division of laborB. show the advantages of the old craft systemC. emphasize how powerful the individual worker wasD. emphasize the importance of increased production24. According to the writer, Adam Smiths mistake was in believing that division of laborA. was an efficient way of organizing workB. was an important development in methods of productionC. inevitably led to economic developmentD. increased the production of existing goods25. The division of labor may become inefficient in organizing work if A. it is taken too far B. it is taken for granted C. it is made use of on a regular base D. it is widely used21. C 22. B 23. A 24. C 25. AWe all know that the normal human daily cycle of activity is of some 7-8 hours sleep alternating with some 16-17 hours wakefulness and that, broadly speaking, the sleep normally coincides with the hours of darkness. Our present concern is with how easily and to what extent this cycle can be modified.The question is no mere academic one. The ease, for example, with which people can change from working in the day to working at night is a question of growing importance in industry where automationcalls for round-the-clock working of machines. It normally takes from five days to one week for a person to adapt to a reversed routine of sleep and wakefulness, sleeping during the day and working at night. Unfortunately, it is often the case in industry that shifts are changed every week; a person may work from 12 midnight to 8 a. m. one week, 8 a. m. to 4 p. m. the next, and 4 p.m. to 12 midnight the third and so on. This means that no sooner has he got used to one routine than he has to change to another, so that much of his time is spent neither working nor sleeping very efficiently.The only real solution appears to be to hand over the night shift to a number of permanent night workers. An interesting study of the domestic life and health of night-shift workers was carried out by Brown in 1957. She found a high incidence (发生率) of disturbed sleep and other disorders among those on alternating day and night shifts, but no abnormal occurrence of these phenomena among those on permanent night work.This latter system then appears to be the best long-term policy, but meanwhile something may be done to relieve the strains of alternate day and night work by selecting those people who can adapt most quickly to the changes of routine. One way of knowing when a person has adapted is by measuring his body temperature. People engaged in normal daytime work will have a high temperature duringthe hours of wakefulness and a low one at night; when they change to night work the pattern will only gradually go back to match the new routine and the speed particularly in terms of performance. Therefore, by taking body temperature at intervals of two hours throughout the period of wakefulness it can be seen how quickly a person can adapt to a reversed routine, and this could be used as a basis for selection. So far, however, such a form of selection does not seem to have been applied in practice.26. Why is the question of "how easily people can get used to working at night" no mere academic one?A. Because few people like to reverse the cycle of sleep and wakefulness.B. Because sleep normally coincides with the hours of darkness.C. Because people are required to work at night in some fields of industry.D. Because shift work in industry requires people to change their sleeping habits.27. The main problem of the round-the-clock working system lies in_______.A. the inconveniences brought about to the workers by the introduction of automationB. the disturbance of the daily cycle of workers who have to changeshifts too frequentlyC. the fact that people working at night are often less effectiveD. the fact that it is difficult to find a number of good night workers28. The best solution for implementing the 24-hour working system seems to be_______.A. to change shifts at longer intervalsB. to have longer shiftsC. to employ people who work on night shifts onlyD. to create better living conditions for night workers29. It is possible to find out if a person has adapted to the changes of routine by measuring his body temperature because______.A. body temperature changes when the cycle of sleep and wakefulness alternatesB. body temperature changes when he changes to night shift or backC. the temperature reverses when the routine is changedD. people have higher temperatures when they are working efficiently30. Which of the following statements is NOT TRUE?A. Body temperature may serve as an indication of a workers performance.B. The selection of a number of permanent night shift workers hasproved to be the best solution to problems of the round-the-clock working system.,C. Taking body temperature at regular intervals can show how a person adapts to the changes of routine.D. Disturbed sleep occurs less frequently among those on permanent night or day shifts.26. D 27. B 28. C 29. D 30. B。
大学英语四级级阅读理解每日一练
大学英语四级级阅读理解每日一练一Recent research has claimed that an excess of positive ions in the air can have an ill effect on peoples physical or psychological health. What are positive ions Well， the air is full of ions，electrically charged particles， and generally thereis a rough balance between the positive and thenegative charged. But sometimes this balance becomes disturbed and a larger proportion of positive ions are found. This happens naturally before thunderstorm，earthquakes when winds such as the Mistral， Hamsin or Sharav are blowing in certain countries. Or it can be caused by a build-up of static electricity indoorsfrom carpets or clothing made of man-made fibres， or from TV sets， duplicators or computer display screens. When a large number of positive ions are present inthe air many people experience unpleasant effects such as headaches， fatigue， irritability， and someparticularly sensitive people suffer nausea or even mental disturbance. Animals are also affected，particularly before earthquakes， snakes have been observed to come out of hibernation， rats to flee from their burrows， dogs howl and cats jump about unaccountably. This has led the US Geographical Survey to fund a network of volunteers to watch animals in an effort to foresee such disasters before they hit vulnerable areas such as California. Conversely，when large numbers of negative ions are present， then people have a feeling of well-being. Natural conditions that produce these large amounts are near the sea， close to waterfalls or fountains， or in any place where water is sprayed， or forms a spray. This probably accounts for the beneficial effect of a holiday by the sea， or in the mountains with tumbling streams or waterfalls. To increase the supply of negative ions indoors， some scientists recommend the use of ionisers： small portable machines， which generate negative ions. They claim that ionisers not only clean and refresh the air but also improve thehealth of people sensitive to excess positive ions. Of course， there are the detractors， other scientists，who dismiss such claims and are skeptical about negative/positive ion research. Therefore people can only make up their own minds by observing the effects on themselves， or on others， of a negative rich or poor environment. After all it is debatable whether depending on seismic readings to anticipate earthquakes is more effective than watching the cat.1.What effect does exceeding positive ionization have on some peopleA.They think they are insane.B.They feel rather bad-tempered and short-fussed.C.They become violently sick.D.They are too tired to do anything.2.In accordance with the passage， static electricity can be caused by___.ing home-made electrical goods.B.wearing clothes made of natural materials.C.walking on artificial floor coverings.D.copying TV programs on a computer.3.A high negative ion count is likely to befound___.A.near a pound with a water pump.B.close to a slow-flowing river.C.high in some barren mountains.D.by a rotating water sprinkler.4.What kind of machine can generate negative ions indoorsA.Ionisers.B.Air-conditioners.C.Exhaust-fansD.Vacuum pumps.5.Some scientists believe that___.A.watching animals to anticipate earthquakes is more effective than depending on seismography.B.the unusual behavior of animals cannot be trusted.C.neither watching nor using seismographs is reliable.D.earthquake答案：BCDAA二Which is safer-staying at home， traveling to work on public transport， or working in the officeSurprisingly， each of these carries the same risk，which is very low. However， what about flying compared to working in the chemical industry Unfortunately， the former is 65 times riskier than the latter! In fact， the accident rate of workers in the chemical industry is less than that of almost any of human activity， and almost as safe as staying at home.The trouble with the chemical industry is that when things go wrong they often cause death to those living nearby. It is this which makes chemical accidents so newsworthy. Fortunately， they are extremely rare. The most famous ones happened at Texas City (1947)，Flixborough (1974)， Seveso (1976)，Pemex (1984) and Bhopal (1984)。

大学生英语四级考试阅读练习题及答案大学生英语四级考试阅读精选练习题及答案英语作为文科科目当中的一个重要组成部分，需要记忆理解的东西比理科要多的多，所以复习的战线需要拉得更长，下面是小编为大家搜索整理的英语四级辅导练习，希望能给大家带来帮助!According to a survey, which was based on the responses of over 188,000 students, today’s traditional-agecollege freshmen are ”more materialistic and less altruistic (利他主义的)” than at any time in the 17 years of the poll.Not surprising in these hard times, the student’s major objective “is to be financially well o ff. Less important than ever is developing a meaningful philosophy of life.” It follows then that today the most popular course is not literature or history but accounting.Interest in teaching, social service and the“altruistic”fields is at a low. On the other hand, enrollment in business programs, engineering and computer science is way up.That’s no surprise either. A friend of mine (a sales representative for a chemical company) was making twice the salary of her college instructors her first year on the job-even before she completed her two-yearassociate degree.While it’s true that we all need a career, it is equally true that our civilization has accumulated an incredible amount of knowledge in fields far removed from our own and that we are better for our understanding of these other contributions m be they scientific or artistic. It is equally true that, in studying thediverse wisdom of others, we learn how to think. More important, perhaps, education teaches us to see the connections between things, as well as to see beyond our immediate needs.Weekly we read of unions who went on strike for higher wages, only to drive their employer out of business.No company; no job. How shortsighted in the long run!But the most important argument for a broad education is that in studying the accumulated wisdom of the ages, we improve our moral sense. I saw a cartoon recently which shows a group of businessmen looking puzzled as they sit around a conference table; one of them is talking on the intercom (对讲机): “Miss Baxter,”he says, “could you please send in someone who can distinguish right from wrong?”From the long-term point of view, that’s what education really ought to be about.练习题：Choose correct answers to the question:1. According to the author’s observati on, college students _______.A. have never been so materialistic as todayB. have never been so interested in the artsC. have never been so financially well off as todayD. have never attached so much importance to moral sense2. The students’ criteria for selecting majors today have much to do with _______.A. the influences of their instructorsB. the financial goals they seek in lifeC. their own interpretations of the coursesD. their understanding of the contributions of others3. By saying “While it’s true that ... be they scientific or artistic” (Lines 1-3, Para. 5), the author means that _______.A. business management should be included in educational programsB. human wisdom has accumulated at an extraordinarily high speedC. human intellectual development has reached new heightsD. the importance of a broad education should not be overlooked4. Studying the diverse wisdom of others can ________.A. create varying artistic interestsB. help people see things in their right perspectiveC. help improve connections among peopleD. regulate the behavior of modern people5. Which of the following statements is true according to the passage?A. Businessmen absorbed in their career are narrow-minded.B. Managers often find it hard to tell right from wrong.C. People engaged in technical jobs lead a more rewarding life.D. Career seekers should not focus on immediate interests only.参考答案1.[A]事实细节题。

The fridge is considered necessary. It has been so since the 1960s when packaged food list appeared with the label: "Store in the refrigerator."In my fridgeless Fifties childhood, 1 was fed well and healthy. The milkman came every day, the grocer, the butcher (肉商), the baker, and the ice-cream man delivered two or three times each week. The Sunday meatwould last until Wednesday and surplus(剩余的) bread and milk became all kinds of cakes. Nothing was wasted, and we were never troubled by rotten food. Thirty years on food deliveries have ceased, fresh vegetables are almost unobtainable in the country.The invention of the fridge contributed comparatively little to the art of food preservation. Many well-tried techniques already existed -- natural cooling, drying, smoking, salting, sugaring, bottling...What refrigeration did promote was marketing --- marketing hardware and electricity, marketing soft drinks, marketing dead bodies of animals around the world in search of a good price.Consequently, most of the world’s fridges are to be found, not in the tropics where they might prove useful, but in the rich countries with mild temperatures where they are climatically almost unnecessary. Every winter, millions of fridges hum away continuously, and at vast expense, busily maintaining an artificially-cooled space inside an artificially-heated house -- while outside, nature provides the desired temperature free of charge.The fridge’s effect upon the environment has been evident, while its contribution to human happiness has been not important. If you don’t believe me, try it yourself, invest in a food cabinet and mm off your fridge next winter. You may not eat the hamburgers(汉堡包), but at least you’ll get rid of that terrible hum.练习题：Choose correct answers to the question:1.The statement "In my fridgeless fifties childhood, I was fed well and healthily." suggests that______.A.the author was well-fed and healthy even without a fridge in his fifties.B.the author was not accustomed to fridges even in his fifties.C.there was no fridge in the author’s home in the 1950s.D.the fridge was in its early stage of development in the 1950s.2.Why does the author say that nothing was wasted before the invention of fridges?A.People would not buy more food than was necessary.B.Food was delivered to people two or three times a week.C.Food was sold fresh and did not get rotten easily.D.People had effective ways to preserve their food.3.Who benefited the least from fridges according to the author?A. Inventors.B. Consumers.C. Manufacturers.D. Travelling salesmen.4.Which of the following phrases in the fifth paragraph indicates the fridge’s neg ative effect on the environment?A.“Hum away continuously”.B.“Climatically almost unnecessary”.C.“Artificially-cooled space”.D.“With mild temperatures”.5.What is the author’s overall attitude toward fridges?A.

大学英语四级阅读理解练习题和答案解析大学英语四级阅读理解练习题：【原文】The Earth comprises three principal layers: the dense, iron-rich core, the mantle made of silicate (硅酸盐) that are semi-molten at depth, and the thin, solid-surface crust There are two kinds of crust, a lower and denser oceanic crust and an upper，lighter continental crust found over only about 40 percent of the Earths surface. The rocks of the crust are of very different ages. Some continental rocks are over 3,000 million years old, while those of the ocean floor are less than 200 million years old. The crusts and the top, solid part of the mantle, totaling about 70 to 100 kilometers in thickness, at present appear to consist of about 15 rigid plates, 7 of which are very large. These plates move over the semi-molten lower mantleto produce all of the major topographical(地形学的)features of the Earth. Active zones where intense deformation occur are confined to the narrow, interconnecting boundaries of contact of the plates.There are three main types of zones of contact: spreading contacts where plates move apart, converging contacts where plates move towards each other, and transform contacts where plates slide past each other. Newoceanic crust is formed along one or more margins of each plate by material issuing from deeper layers of the Earth s crust, for example, by volcanic eruptions (爆发) of lava (火山熔岩) at mid-ocean ridges. If at such a spreading contact the two plates support continents，a rift(裂缝) is formed that will gradually widen and become flooded by the tea. The Atlantic Ocean formed like this as the American and Afro-European plates moved in opposite directions. When two plates carrying continents collide, the continental blocks,too light to be drawn down, continue to float and therefore buckle (起褶皱) to form a mountain chain along the length of the margin of the plates.大学英语四级阅读理解练习题：【题目】Choose correct answers to the question:1.The Earths crust______.A.can be classified into two typesB.is formed along the margins of the platesC.consists of semi-molten rocksD.is about 70 to 100 kilometers thick2.The 15 plates of the Earth are formed from ___.A.the oceanic crusts and continental crustsB.the crusts and the mantleC.the crusts and the top and solid part of the mantleD.the continental crusts and the solid part of the mantle3.Seriously-deformed zones appear _______A.whenever the crusts move over mantleB.when the plates move towards each otherC.in the narrow boundaries where two plates meetD.to be the major topographical feature of the Earth4.According to the second paragraph, the formation of the Atlantic Ocean is the example of_______.A.spreading contactsB.the influence of volcanic eruptionsC.converging contactsD.transform contacts5.This passage is probably_______.A.a newspaper advertisementB.a chapter of a novelC.an excerpt from a textbookD.a scientific report of new findings大学英语四级阅读理解练习题：【答案】1.[A] 事实细节题。

大学英语四级阅读练习附答案Since we are social beings, the quality of our lives depends in large measure on our interpersonal relationships. One strength of the human condition is our tendency to give and receivesupport from one another under stressful circumstances. Social support consists of the exchange of resources among people based on theirinterpersonal ties. Those of us with strong supportsystems appear better able to cope with major life changes and daily hassles 困难. People with strong social ties live longer and have better health than those without such ties. Studies over arange of illnesses, from depression to heart disease, reveal that the presence of social support helps people fend off 挡开 illness, and the absence of such support makes poor health morelikely.Social support cushions stress in a number of ways. First, friends, relatives, and co-workers may let us know that they value us. Our self-respect is strengthened when we feel accepted byothers despite our faults and difficulties. Second, other people often provide us with informational support. They help us to define and understand our problems and find solutions to them.Third, we typically find social companionship supportive. Engaging in leisure-time activities with others helps us to meet our social needs while at the same time distracting 转移…注意力 us fromour worries and troubles. Finally, other people may give us instrumental support—financial aid, material resources, and needed services—that reduces stress by helping us resolve and cope withour problems.36. Interpersonal relationships are important because ________.A they are indispensable to people’s social well-beingB the y awaken people’s desire to exchange resourcesC they help people to cope with life in the information eraD they can cure a range of illnesses such as heart disease, etc37.

They will soil your house, destroy your belongings, bark excessively, fight other dogs and even biteyou. Nearly all behavior problems are perfectly normal dog activities that occur at the wrong time or place or are directed at the wrong thing. The key to preventing or treating behaviorproblems is learning to teach the dog to redirect its normal behavior to outlets that are acceptable in the domestic setting.One of the best things you can do for your dog and yourself is to obedience train it. Obedience training doesn’t solve all behavior problems, but it is the foundation for solving just aboutany problem. Training pens up a line of communication between you and your dog. Effective communication is necessary to instruct your dog about what you want it to do.Training is also an easy way to establish the social rank order. When your dog obeys a simple request of “come here, sit,” it is showing obedience and respect for you. It is not necessary toestablish yourself as top dog or leader of the pack 群 by using extreme measure. You can teach your dog its subordinate 从属的 role by teaching it to show submission to you. Most dogs loveperforming tricks for you to pleasantly accept that you are in charge.Training should be fun and rewarding for you and your dog. It can enrich your relationship and make living together more enjoyable. A well-trained dog is more confident and can more safely beallowed a greater amount of freedom than an untrained animal.21.

More and more, the operations of our businesses, governments, and financial institutions are controlled by information that exists only inside computer memories. Anyone clever enough to modify this information for his own purposes can reap big reward. Even worse, a number of people who have done this and been caught at it have managed to get away without punishment.It’s easy for computer crimes to go undetected if no one checks up on what the computer is doing. But even if the crime is detected, the criminal may walk away not only unpunished but with a glowing recommendation from his former employers.Of course, we have no statistics on crimes that go undetected. But it’s disturbing to note how many of the crimes we do know about were detected by accident, not by systematic inspections or other security procedures. The computer criminals who have been caught may have been the victims of uncommonly bad luck.Unlike other lawbreakers, who must leave the country, commit suicide, or go to jail, computer criminals sometimes escape punishment, demanding not only that they not be charged but that they be given good recommendations and perhaps other benefits. All too often, their demands have been met.Why? Because company executives are afraid of the bad publicity that would result if the public found out that their computer had been misused. They hesitate at the thought of a criminal boasting in open court of how he juggled (诈骗) the most confidential （保密）records right under the noses of the company’s executives, accountants, and security staff. And so another computer criminal departs with just the needs to continue his crimes elsewhere.1. It can be concluded from the passage that _______________.A) it is still impossible to detect computer crimes todayB)people commit computer crimes at the request of their companyC) computer criminals escape punishment because they can’t be detectedD) computer crimes are the most serious problem in the operation of financial institutions2. It is implied in the third paragraph that _________________.A) most computer criminals who are caught blame their bad luckB)the rapid increase of computer crimes is a troublesome problemC) most computer criminals are smart enough to cover up their crimesD) many more computer crimes go undetected that are discovered3. Which of the following statements is mentioned in the passage?A) A strict law against computer crimes must be enforcedB) Companies usually hesitate to uncover computer crimes to protect their reputationC) Companies will guard against computer crimes to protect their reputationD) Companies need to impose restrictions on confidential information4. What may happen to computer criminals once they are caught?A) With a bad reputation they can hardly find another job.B)They may walk away and easily find another job.C) They will be denied access to confidential recordsD) They must leave the country to go to jail.5. The passage is mainly about _________________.A) why computer criminals are often able to escape punishmentB)why computer crimes are difficult to detect by systematic inspectionsC) how computer criminals mange to get good recommendations from their former employersD) why computer crimes can’t be eliminated1. D) 本题主要由第一段的内容推理出来，同时兼用排除法。

以下是店铺为大家搜索整理的大学CET4考试阅读练习及答案，希望能个大家带来帮助!The motor vehicle has killed and disabled more people in its brief history than any bomb or weapon ever invented. Much of the blood on the street flows essentially from uncivil behavior of drivers who refuse to respect the legal and moral rights of others. So the massacre on the road may be regarded as a social problem.In fact, the enemies of society on wheels are rather harmless people or ordinary people acting carelessly, you might say. But it is a principle both of law and common morality that carelessness is no excuse when one's actions could bring death or damage to others. A minority of the killers go even beyond carelessness to total negligence.Researchers have estimated that as many as 80 per cent of all automobile accidents can be attributed to the psychological condition of the driver. Emotional upsets can distort drivers' reactions, slow their judgment, and blind them to dangers that might otherwise be evident. The experts warn that it is vital for every driver to make a conscious effort to keep one's emotions under control.Yet the irresponsibility that accounts for much of the problem is not confined to drivers. Street walkers regularly violate traffic regulations; they are at fault in most vehicle walker accidents. And many cyclists even believe that they are not subject to the basic rules of the road.Significant legal advances have been made towards safer driving in the past few years. Safety standards for vehicle havebeen raised both at the point of manufacture and through periodic road-worthiness inspections. In addition, speed limits have been lowered. Due to these measures, the accident rate has decreased. But the accident experts still worry because there has been little or no improvement in the way drivers behave. The only real and lasting solution, say the experts, is to convince people that driving is a skilled task requiring constant care and concentration. Those who fail to do all these things pose a threat to those with whom they share the road.62. The word “massacre” in line 3 paragraph one means _____A) mass-killing.B) disaster.C) tragedy.D) accident.63. What is the author's main purpose in writing the passage?A) T o show that the motor vehicle is a very dangerous invention.B) To promote understanding between careless drivers and street walkers.C) To discuss traffic problems and propose possible solutions.D) To warn drivers of the importance of safe driving.64. According to the passage, traffic accidents may be regarded as a social problem because _____.A) autos have become most destructive to mankindB) people usually pay little attention to law and moralityC) civilization brings much harm to peopleD) the lack of virtue is becoming more severe65. Why does the author mention the psychological condition of the driver in Paragraph Three?A) To give an example of the various reasons for road accidents.B) To show how important it is for drivers to be emotionally healthy.C) To show some of the inaccurate estimations by researchers.D) To illustrate the hidden tensions in the course of driving.66. Who are NOT mentioned as being responsible for the road accidents?A) Careless bicycle-riders.B) Mindless people walking in the street.C) Irresponsible drivers.D) Irresponsible manufactures of automobiles.答案解析:62-66：ACBBD。

When we analyze the salt salinity of ocean waters, we find that it varies only slightly from place to place. Nevertheless, some of these small changes are important. There are three basic processes that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporation. In this manner, the salinity is increased, since the salt stays behind. If this is carried to the extreme, of course, white salt would be left behind; this, by the way, is how much of the table salt we use is actually obtained.The opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. Here the ocean is being diluted so that the salinity is decreased. This may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. Thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation.Normally, in hot regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. Similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.A third process by which salinity may be altered is associatedwith the formation and melting of sea ice. When seawater is frozen, the dissolved materials are left behind.. In this manner, seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. Of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.In the Weddell Sea, the densest water in the ocean is formed as a result of this freezing process, which increases the salinity of cold water. This heavy water sinks and is found in the deeper portion of the oceans of the world.26. This passage mainly tells us about_______.A. the analysis of the salinity of ocean watersB. the causes of the variation in oceanic salinityC. the importance of the changes in oceanic salinityD. the different forms of salts in ocean waters27.It can be known from the passage that increase in the salinity of ocean water is caused by______.A. melting of sea iceB. precipitationC. evaporationD. supplement of salt28.Which of the following is not the cause of the decrease in the oceanic salinity?A. Precipitation.B. Rain and snow.C. Formation of ice.D. Addition of water by rivers.29.Which of the following statements is TRUE according to the passage?A. Oceanic salinity has great effect on sea life.B. Many factors combine to cause changes in oceanic salinity.C. The movement of the water is related to the amount of salt.D. The temperature of the water has much to do with theoceanic salinity.30.The purpose of mentioning the Weddell Sea is_______.A. to give an example of cold-water salinityB. to point out the location of deep watersC. to make a comparison between hot-water salinity and cold-water salinityD. to show that the water in the Weddell Sea varies in salinity from place to place答案：26. B 27. C 28. C 29. D 30. A大学英语四级考试阅读练习题及答案篇1Not all sounds made by animals serve as language, and we have only to turn to that extraordinary discovery of echolocation (回声定位) in bats to see a case in which the voice plays a strictly practical role.To get a full appreciation of what this means we must turn first to some recent human inventions. Everyoneknows that if he shouts near a wall or a mountainside, an echo will come back. The further off this solid obstacle, the longer time it will take for the return of the echo. A sound made by tapping on the main body of a ship will be reflected from the sea bottom, and by measuring the time interval between the taps andthe receipt of the echoes the depth of the sea at that point can be calculated. So was born the echo-sounding equipment, now in general use in ships. Every solid object will reflect a sound, varying according to the size and nature of the object. A shoal of fish will do this. So it is a comparatively simple step fromlocating the sea bottom to locating a shoal of fish. With experience, and with improved equipment, it is now possible not only to locate fish but to tell if it is herring, cod, or other well-known fish, by the pattern of its echo.A few years ago it was found that certain bats emit squeaks (吱吱声) and by receiving ’he echoes they could locate and steer clear of obstacles--or locate flying insects on which they feed. This echolocation in bats is often compared with radar, the principle of which is similar.练习题：Choose correct answers to the question:1.The main purpose of this passage is to ______.A. describe that animals can make different soundsB. prove that animals’ voices can play practical rolesC. inspire the readers to make more inventionsD. startle the readers with some shocking facts2. The discovery of echolocation may help with all of the following EXCEPTA. measuring the depth of the seaB. distinguishing different kinds of fishC. improving the functions of radarD. varying the size and nature of an object3. By saying "A shoal of fish will do this"(Lines 6-7, Para. 2), the author means ________.A. only one special kind of fish can reflect soundsB. only one special kind of fish can be used to help locate a shipC. a large group of fish can reflect soundsD. a large group of fish can be used to help locate a ship4. As it is discussed in the passage, the squeaks of bats can be functionally compared with ________.A. human languagesB. a mountainsideC. a shoal of fishD. taps on a ship5. Which of the following statements can be inferred from the passage?A. Animals are more intelligent than humans.B. Humans are more intelligent than animals.C. Animals are often compared with human inventions.D. Humans are often inspired by animals.答案解析1.[B] 主旨大意题。

It is said that the Englishman objects to this type of existence, but if the case is such, he does in fact differ from the inhabitants of most countries of the world today. In the past our own blocks of flats have been associated with the lower-income groups and they have lacked the obvious provisions, such as central heating, constant hot water supply, electrically operated lifts from top to bottom, and so on, as well as such details, important notwithstanding, as easy facilities for disposal of dust and rubbish and storage places for baby carriages on the ground floor, playgrounds for children on the top of the buildings, and drying grounds for washing. It is likely that the dispute regarding flats versus individual houses will continue to rage on for a long time as for as Britain is concerned. And it is unfortunate that there should be hot feelings on both sides whenever this subject is raised. Those who oppose the building of flats base their case primarily on the assumption that everyone prefers an individual home and garden and on the high cost per unit of accommodation. The latter ignores the higher cost of providing full services to a scattered community and the cost in both money and time of the journeys to work for the suburban resident.71. We can infer from the passage that________A) English people, like most people in other countries, dislike living in flatsB) People in most countries of the world today are not opposed to living in flatsC) People in Britain are forced to move into high blocks of flatsD) Modern flats still fail to provide the necessary facilities for living72. What is said about the blocks of flats built in the past in Britain ?A) They were mostly inhabited by people who did not earn much.B) They were usually not large enough to accommodate big families.C) They were sold to people before necessary facilities were installed.D) They provided playground for children on the top of the buildings73. The word “rage”(Line 10) means “______”A) be ignored B) develop with great forceC) encourage people greatly D) be in fashion74. Some people oppose the building of flats because________A) the living expenses for each individual family are higherB) it involves higher cost compared with the building of housesC) they believe people like to live in houses with gardensD) the disposal of rubbish remains a problem for those living in flats75.The author mentions that people who live in suburban houses________A) do not have access to easy facilities because they live away from the cityB) have to pay a lot of money to employ people to do service workC) take longer time to know each other because they are a scattered communityD) have to spend move money and time traveling to work every day.Passage 15英国几乎比世界上任何其他国家都更应该严肃的面对高层建筑问题，也就是说，在高层公寓内容纳相当大的一部分人口的问题。
（７１）据说英国人反对这种建筑的存在，但如果真是这样，英国人的确与当今世界上的大多灵敏国家的居民不同。
（７２）过去，我们的多层公寓一直是与低收入人群联系起来的，它们缺乏必要的供应，例如中央供暖，不断的热水供应，从顶层到底层的电梯等等，以及诸如此类的细微之处，而最令人难以忍受的是处理灰尘和垃圾的方便设施与存放婴儿车的地方在一楼，孩子们玩耍的运动场在顶楼，烘干层是用来洗衣服的。
（７３）就英国来说，关于公寓与个人单独的房屋之间的争议很有可能继续激烈地进行下去，持续很长时间。
不幸的是，不论何时只要提到这个问题，双方都会激动起来。
（７４）那些反对公寓建筑的人主要是基于这样一种设想，即所有的人都喜欢有一个自己独立的房间与花园以及公寓住房每个铺位昂贵的花销。
而后面这个原因忽略了为一个分散的社区提供一切服务所需要的较高费用以及（７５）从郊区的住所去上班所花的时间与金钱。
