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

How much was it ?a. 60%b. 50%c. 33%d. 90%答案：cdabc三Women are also underrepresented in the administration and this is because there are so few women full professors. In 1985,Regent Beryl Milburn produced a report blasting the University of Texas System adminitration for not encouraging women.The University was rated among the lowest for the system.In a 1987 update ,Milburn commended the progress that was made and called for even more improvement.One of the positive results from her study was a System-wide program to inform women of available administrative jobs.College of Communication Associate Dean Patrica Witherspoon,said it isimportant 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 thissystem.If they spend their time in little groups mourning the sexual discrimination that they think exists here, they are wasting valuable study time."1.According to Spirduso,women need to ____.a.produce a report on sexual discriminationb.call for further improvement in their working conditionsc.spend their energies and time fighting against sexual discriminationd.spend more time and energy doing scholarly activities2.From this passage ,we know that _____.a.there are many women full professors in the University of Texasb.women play an important part in adminitrating the Universityc.the weather on the campus is chillyd.women make up a small percentage of the senior positions in the University3.Which of the following statements is true?a.the number of women professors in the University in 1987 was greater than that of 1985b.the number of women professors in the University in 1987 was smaller than that of 1985c.the number of women professors was the same as that of 1985d.more and more women professors thought that sexual discrimination did exit in the University4.One of the positive results from Milburn's study was that _____. a.women were told to con centrate on teir workb.women were given information about available administrative jobsc.women were encouraged to take on all the administrative jobs in the Unversityd.women were encouraged to do more scholarly activities5. The title for this passage should be _______.a.The University of Texasburn's Reportc.Women Professorsd.Sexual Discrimination in Academia答案：ddabd四Today ,as in every other day of the year ,more than 3000 U.S. adlescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime,it can be expected that of these 3000 about 23 will be murdered,30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweithts all other factors, whether voluntary or involuntary, as a cause of death.Since the late 1970s, when daily smoking among high school seniors reached 30 precent , smoking rates among youth have declined . While the decline isimpressive ,several important issues must be raised.First, in the past several years,smoking rates among youth have declined very little. Second,in the late 1970s ,smoking among male high school seniors exceeded that among female by nearly 10 percent . The statistic is reversing.Third ,several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent .Finally, thouth significant declines in adolescent smoking have occurred in the past decade,no definite reasons for the decline exist. Within this context,the Naional Cancer Instiute (NCI began its current effort to determine the most effecive measures to reduce smoking levesl among youth.1.According to the author, the deaths among youth are mainly caused by _____.a.traffic accidentsb.smoking-related deseasec.murderd.all of these2.Every day there are over_____high school strdents who will become regular smoker.a.75b.23c.30d.30003.By "dropout" the author means______.a.students who failed the examinationb.students who left schoolc.students who lost their wayd.students who were driven out of school4.The reason for declining adolescent smoking is that ________.a.NCI has taken effective measuresb.smoking is prevented among high school seniorsc.there are many smokers who have died of cancerd.none of these5.What is implied but not stated by the author is that ________.a.smoking rates among youth have declined very littleb.there are now more female than male smokers among high school seniorsc.high smoking rates are due to the incease in wealthd.smoking at high school are from low socio-economic backgrounds答案：bdbdb五The food we eat seems to have profound effects on our health.Although science has made enormous steps in making food more fit to eat ,it has, at the same time,made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet aswell,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additivies,caused cancer. Yet, thesecarcinogenic 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。

As the pace of life continues to increase ,we are fast losing the art of relaxation. Once you are in the habit of rushing through lift,being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.Stress is an natural part of everyday lift and there is no way to avoid it. In fact ,it is not the bad thing it is often supposed to be .A certain amount of stress is vital to provide motivation adn give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress,and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress,in whatever form,we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme,but however little the stress,it involves the same response. It is when such a reaction lasts long,through continued exposure to stress,that health becomes endangered.Such serious conditions as high blood pressure and heart disease have established links with stress.Since we cannot remove stress from our lives(it would be unwise to do so even if we could),we need to find ways to deal with it.1.People are finding less and less time for relaxing themselves because_____.a.they do not know how to enjoy themselvesb.they do not believe that relaxation is important for healthc.they are travelling fast all the timed.they are becoming busier with their work2.According to the writer ,the most important character for a good manager is his ________.a.not fearing stressb.knowing the art of relaxationc.high sense of responsibilityd.having control over performance3.Which of the follwing statements is ture?a.We can find some ways to avoid stressb.Stress is always harmful to peoplec.It is easy to change the hagit of keeping oneself busy with work.d.Different people can withstand different amounts of stress4.In Paragraph 3, "such a reaction" refers back to_______.a."making a choice between 'flight' or 'fight'"b."reaction to stress both chemically and physically"c."responding to crises quickly"d."losing heart at the signs difficulties"5.In the last sentence of the passage,"do so " refers to ______.a."expose ourselves to stress"b."find ways to deal with stress"c."remove stress from our lives"d."established links between diseases and stress"答案：dadbcIn the 1960s, many young Americans were dissatisfied with American society. They wanted to end the Vietnam War and to make all of the people in the U.S. epual. Some of them decided to "drop out" of American society and form their own societies . They formed utopian communities , which they called "communes," where they could follow their philosophy of "do your own thing." A group of artists founded a commune in southern Colorado called "Drop City." Following the ideas of philosopher and architect Buckminster Fuller they built domeshaped houses from pieces of old cars. Other groups, such as author Ken Kesey's Merry Pranksters, the followers fo San Francisco poet Steve Gakin, and a group that called itself the Hog Farm, lived in old school huses and traveled around the United States. The Hog Farm become famous when they helped organize the Woodstock Rock Festival in 1969. Steve Gaskin's followers tried to settle down on a farm in Tennessee, but they had to leave when some members of the gruop were arrested for growing marijuana.Not all communes believed in the philosophy of "do you own thing," however . Twin Oaks , a commune founded in Virgiania in the late 1960s, was based on the ideas of psychologist B.F.Skinner. The people who lived at Twin Oaks were carefully controlled by Skinner's "conditioning" techniques to do things that were good for the community. In 1972, Italian architect Paolo Soleri began to build Arcosanti, a utopian city Arizsona where 2500 people will live closely together in one large building called an "archology" Soleri believes that people must live closely together so that they will all become one.1.Why did some young Americans decide to "drop out" of scoiety during the 1960s?a.They were not satisfied with American society.b.They wanted to grow marijuana.c.They wanted to go to the Vietnam War.d.They did not want all people to be equal.2.Where did the members of the Hog Farm commune live?a.In dome-shaped houseb.In old school husesc.On a farm inTennesseed.In an archology in Arizona3.Who gave the people of Drop City the idea to bulid dome-shaped house?a.Paolo Solerib.B.G.Skinnerc.Steve Gaskind.Buckminster Fuller4.What was the Twin Oaks commune base on ?a.The philosophy of "do your own thing"b.Virginaia in the late 1960sc.The ideas of psychologistd.The belief that people must live closely togerher.5.What is an "archology"?a.A person who studies archaeologyb.A large building where people live closely togetherc.A city in A rizonad.A technique to contorl people答案：abdcbThere are two factors which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual—the sort of environment in which he is reared. If an individual is handicapped envionmentally ,it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.The importance of environment in determining an individual's intellingence can be demonstrated by the case history of the identical twins, Peter and Mark X. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old , their parents died, and they were placed in separate foster homes. Peter was reated by parents of low intelligence in an isolatedcommunity with poor educational pooprtunities.Mark was reared inthe home of well-to-do parents who had been to college. He was read to as a child , sent to good schools, and given every opportunity to be stimulated intellectually.This enviromental difference continued until the twins were in their late teens, when they were giben tesets to measure their intelligence. Mark's I.Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities , the twins , having identical brains,would have tested at roughly the same level.1.This selection can best be titled_________.a.Measuring Your Intelligenceb.Intelligence and Environmentc.The Case of Peter and Markd.How the brain Influences Intelligence2.The beststatement of the main idea of this passage is that _____.a.human brains differ considerablyb.the brain a person is born with is improtant in determining his intelligencec.environment is crucial in determining a person's intelligenced. persons having identical brains will have roughly the same intelligence3.According to the passage , the average I.Q.is _____.a.85b.100c.110d.1254.The case history of the twins appears to support the conclusion that _______.a.individual with identical brains seldom test at same levelb.an individual's intelligence is determined only by his enviromentck of opportunity blocks the growth of intelligenced.changes of enviroment produce changes in the structure of the brain5.This passage suggests that an individual 's I.Q.______.a.can be predicted at birthb.stays the same throuthout his lifec.can be increased by educationd.is determined by his childhood答案：bcbccAs she walked round the huge department store,Edith reflected how difficult it was to choose a suitable Christmas present for her father.She wish that he was as easy to please as her mother, who was always delighted with perfumeBesides,shoppong at this time of the year was a most disgreeable experience :people trod on yourtoes,poked you with their elbows and almost knocked you overin their haste to get to a bargain ahead of you.Partly to have a rest, Edith paused in front of a counter where some attracive ties were on display.

But none of the other planets in our solar system are capable of supporting life at present. One possible solution to the problem, however,has recently been suggested by American scientist, Professor Carl Sagan.Sagan believes that before the earth's resources are compleetely exhausted it will be possible to change the atmophere of Venus and so create a new world almost as large as earth itself. The difficult is that Venus is much hotter than the earth and there is only a tiny amount of water there.Sagan proposes that algae organisms that can live in extremely hot or cold atmospheres and at the same time produce oxygen,should be bred in condition similar to those on Venus.As soon as this has been done, the algae will be placed in small rockets. Spaceship will then fly to Venus and fire the rockets into the atmosphere .In a fairly short time, the alge will break down the carbon dioxide into oxygen and carbon.When the algae have done theri work, the atmosphere will become cooler,but befor man can set foot on Venus it will be neccessary for the oxygen to produce rain. The surface of the planet will still be too hot for man to land on it but the rain will eventually fall and in a few years something like earth will be reproduced on Venus.1.Inte long run, the most insoluble problem caused by population growth on earth will probably be the lack of ______.a.foodb.oilc.spaced.resources2.Carl Sagan believes that Venus might be colonized from earth because _____a.it might be possible to change its atmosphereb.its atmosphere is the same as the earth'sc.there is a good supply of water on Venusd.the days on Venus are long enough3.On Venus there is a lot of ________.a.waterb.carbon dioxidec.carbon monoxided.oxygen4.Algae are plants that can____.a.live in very hot temperaturesb.live in very cold temperaturesc.manufacture oxygend.all of the above5. Man can land on Venus only when_______.a.the algae have done their workb.the atmosphere becomes coolerc.thereis oxygend.it rains there答案：cabdd。

大学英语四级阅读理解试题及答案（四）十六Trees should only be pruned when there is a good and clear reason for doing so and , fortunately,the number of such reasons is small. Pruning involves the cutting away of obergrown and unwanted branches, and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the tree to grow in its own way.First, pruning may be done to make sure that trees have a desired shape or size.The object may be to get a tree of the right height, and at the same time to help the growth of small side branches which will thicken its appearance or give it a special shape. Secondly, pruning may be done to make the tree healthier. You may cut diseaed or dead wood, or branches that are rubbing against each other and thus cause wounds. The health of a tree may be encouraged by removing branches that are blocking up the centre and so preventing the free movement of air.One result of pruning is that an open wound is left on the tree and this providesan easy entry for disease, but itis awound that will heal. Often there is a race between the healing and the desease asto whether the tree will live or die, so that there is a period when the tree is at risk. It should be the aim of every gardener to reduce which has been pruned smooth and clean, for healing will be slowed down by roughness. You should allow the cut surface to dry for a few hurs and then paint it with one of the substances available from garden shops produced especially for this purpose. Pruning is usually without interference from the leaves and also it is very unlikely that the cuts yu make will bleed. If this does happen,it is, of course,impossible to paint them properly.1.Pruning should be done to ______.a.make the tree grow tallerb.improve the shape of the treec.get rid of the small branchesd.make the small branches thicker2.Trees become unhealthy if the gardener ______. a.allows too many branches to grow in the middleb.does not protect them from windc.forces them to grow too quicklyd.damages some of the small side branches3.Why is a special substance painted on the tree? a.To make a wound smoothb.To prevent disease entering a woundc.To cover a rough surfaced.To help a wound to dry4.A good gardener prunes a tree______.a.at intervals throughout the yearb.as quickly as possiblec.occasionally when necessaryd.regular every winter5.What was the author's purpose when writing this passage? a.To give pratical instruction for pruning a tree.b.To give a general description of pruningc.To explain how trees develop diseasesd.To discuss different methods of pruning.答案： babca十七On Thursday afternoon Mrs. Carke, dressed for going out, took her handbag withher money and her key in it, pulled the door behind her to lock it and went to the over60s Club. She always went there on Thursdays. It was a nice outing for an old woman who lived alone.At six o'clock she cane home, let herself in and at once smelt cigarette smoke. Cigarette smoke in her house? How? How? Had someone got in? She checked the back door and the windows. All were locked or fastened, as usual. There was no sign offorced entry.Over a cup of tea she wondered whether someone might have a key that fittedher front door-"a master key"perhaps. So she stayed at home the following Thursday. Nothing happened. Was anyone watching her movements? On the Thursday after that shewent out at her usual time,dressed as usual, but she didn't go to the club. Instead she took a short cut home again, letting herself in through her garden and the back door. She settled down to wait.It was just after four o'clock when the front door bell rang.Mrs. Clarke was making a cup of tea at the time. The bell rang again, and then she heard her letter-box being pushed open. With the kettle of boiling water in her hand, she moved quietly towards the front door. A long piece of wire appeared through the letter-box, and then a hand. The wire turned and caught around the knob on the door-lock. Mrs. Clarke raised the kettle andpoured the water over the hand. There was a shout outside, and the skin seemed to drop off the fingers like a glove. The wire fell to the floor, the hand was pulled back, and Mrs. Clarke heard the sound of running feet.1.Mrs. Clarke looded forward to Thursday because_______. a.she worked at a club on the dayb.she said visitors on Thursdaysc.she visited a club on Thursdayd.a special visitor came on Thursday2.If someone had made a forced entery,_______.a.Mrs.Clarke would have found a broken door or windowb.he or she was still in the housec.things would have been thown aboutd.he or she would have needed a master key3.On the third Thursday Mrs. Clarke went out_______. a.because she didn't want to miss the club again b.to see if the thief was hnging about outsidec.to the club but then changed her mindd.in an attempt to trick the thief4.The lock on the front door was one which_______. a.needed a piece of wire to open itb.could he opened from inside without a keyc.could't be opened without a keyed a knob instead of a key5.The wire feel to the floor_______.a.because Mrs.Clarke refused to open the doorb.when the man's glove dropped offc.because it was too hot to holdd.because the man justwanted to get away答案： cadbd十八Many people believe the glare from snow causessnowblindnenss. Yet, dark glasses or not , they find themselves sufferingfrom headaches and watering eyes,and evensnowblindness,when exposed to several hours of "snow light" . The United States Army has now determined that glare from snow does not cause snowblindness in troops in a snow-covered country.Rather, a man's eyes frequently find nothing to foucs on in a broad expanse of barren snow-covered terrain. So his gaze continually shifts and jumps back and forth over the entire landscape in search of tsomething to look at. Finding nothing,hour after hour, the eyes never sotp searching and the eyeballs become sore and the eye muscles ache. Nature offsets this irritation by producing more and fluid which covers the eyeball. The fluid coversthe eyeball in increasing quantity until vision blurs, then is obsured,and the result is total, even though temporary,snowblindness.Experiments led the Army to a simple method of overcoming this problem. Scouts ahead of a main body of troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape,Even the scouts themselves throw lightweight , dark colored objects ahead on which they too can focus . The men following can then see something.Their gaze is arrested. Their eyes focus on a bush and having found something to see,stop scouring thesnow-blanketed lanscape. By focusing their attention on one object at a time,themen can cross the snow without becoming hopelessly snowblind or lost.

Our increasing population will tremendously increase urban wastes,primarily sewage. On the other hand, increasing demands for water will decease substantialy the amount of water available for diluting wastes. Rapidly expanding industries which involve more and more complexchemical processes will produce large volumes of liquid wastes, and many of these will contain chemicals which are noxious. To feed our rapidly expanding population,agriculture will have to be intensified. This will involve ever-increasingquantitiesof agricultural chemicals, From this , it is apparent that drastic steps must betaken immediately to develop corrective measures for the pollution problem.There are two ways by which this pollution problem can be dwindled. The first relates to the treatment of wastes to decrease their pollution hazard. This involvesthe processing of solid wastes "prior to " disposal and the treatment of liquid wastes, or efflunets,to permit the reuse of the water or minimize pollution upon final disposal.A second approach is to develop an economic use for all or a part of the wastes. Farm manure is spread in fields as a nutrient or organic supplement . Effluents from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained. Efflunets from other processing plants may also be used as a supplemental source of water. Many industries, such as meat and poultry processing plants, are currently converting former waste products into marketable byproducts. Other industries are potential eonomic uses for waste products.1.The purpose of this passage is ______.a.to alert the reader to the dwindling water supplyb.to explain industrial usesof waterc.to acquaint the reader with water pollution problemsd.to demostratevarious measures to solve the pollution problem2.Which of the following points is NOT INCLUDED in the passage?a.In dustrial development incudes the simplification of complex chemical processes.b.Diluting wastes needs certain amount of waterc.Demands for water will go up along with the expanding populationd.Intensive cultivation of land requires more and more chemicals3.The reader can conclued that________.a.countries of the world will work together on polution problemsb.byproducts from wastes lead to a more prosperous marketplacec.science is making great progress on increasing water suppliesd.some industries are now ,aking economic use of wastes4.The author gives substance to the passage through the use of _______.a.interviews with authorities in the field of water controlsb.opinions and personal observationsc.definitions which clarify important termsd.strong arguments and persuasions5.The words "prior to "(para.2 probably mean______. a.afterb.duringc.befored.beyond答案 :cadbc二十One of the qualities that most people admire in others is the willingness to admit one's mistakes. It is extremely hard sometimes to say a simple thing like "I was wrong about that," and it is even harder to say, "I was wrong , and you were right about that."I had an experience recently with someone admitting to me that he had made a mistake fifteen years ago. He told me he had been the manager of a certain grocery store in the neighbourhood where I grew up, and he asked me if I remembered the egg cartons. Then he related an incident and Ibegan to remember vaguely the incident he was describing.I was about eight years old at the time, and I had gome into the store withmay mother to do the weekly grocery shopping.On that particular day, I must have found my way to the dairy fooddepartment where the incident tood place.There must have been a special sale on eggs that day because there was an impressive display of eggs indozen and half-dozen cartons. The cartons were stacked three or four feet high. I must have stopped in front of a display to admire the stacks.Just then a woman came by pushing her grocery cart and knocked off the stacks of cartons. For some reason, I decided it was up to me to put the display back together, so I want to work. The manager heard the moise and came rushing over to see what had happened. When he appeared, I was on my kneesinspecting some of the cartons to see if any of the eggs were broken, but to him it looked as though I was the culprit. He severely reprimanded me and wanted me to payfor any broken eggs. I protested my innocence and tried to explain, but it did no good. Even though I quickly forgot all about the incident, apparently the manager did not.1.How old was the author when he wrote this article? a.about 8b.about 18c.about 23d.about 15 2.Who was to blame for knocking off the stacks of cartons? a.The author b.The manager c.A woman d.The author's mother 3.Which of the following statements is not true? a.The woman who knocked off the stacks of cartons was seriously criticized by the mananger b.The author was severely critizized by the manager.c.A woman carelessly knocked off the stacks of cartonsd.It was the author who put the display back together 4.Which of the following can serve as the best title for the passage?a.Its Harder to Admit One's Mistakeb.I was once the culpritc.I remember an incidentd.A case of mistaken identity5.The tone of the article expresses the author's_______. a.admiration for the manager'swillingness to admit mistakes b.anger to the manager for his wrong accusationc.indignation against the woman who knocked off the stacks of cartonsd.reget forthe mistake the made in the store答案： ccada。

大学英语四级模拟阅读及答案

Passage OneIt's official: Money can't buy happiness.Sure, if a person is handed $10, the pleasure centres of his brain light up as if he were given food, sex, or drugs. But that initial rush does not translate into long-term pleasure for most people. Surveys have found virtually the same level of happiness between the very rich individuals on the Forbs 400 and the Maasai herdsmen of East Africa. Lottery winners return to their previous level of happiness after five years. Increases in income just don't seem to make people happier-and most negative life experiences likewise have only a small impact on long-term satisfaction."The relati on ship betwee n money and happ in ess is pretty darn ed（非常）small," says Peter Ubel, a professor of medicine at the University of Michigan.That's not to say that increased income doesn't matter at all. There is a very small correlation between wealth and happiness-accounting for about one percent of the happiness reported by people answering the surveys. And for some groups, that relationship may be considerably bigger. People who are poor seem to get much happier when their monetary prospects improve; so do the very sick. In these cases, Ubel speculates, people may be protected from negative circumstances by the extra cash. Another possibility is that the money brings an increase in status, which may have a greater impact on happiness.Why doesn't wealth bring a constant sense of joy? "Part of the reason is that people aren't very good at figuring out what to do with the money," says George Loewenstein, an economist at Carnegie Melton University. People generally overestimate the amount of long-term pleasure they'll get from a given object.Sometimes, Loewenstein notes, the way people spend their money can actually make them less happy. For example, people derive a great deal of pleasure from interacting with others. If the first thing lottery winners do is to quit their job and to move to a palatial（富丽堂皇的）but isolated estate where they don't see any neighbours, they could find themselves isolated and depressed.1. The first sentence of the passage means_.A. it is announced by government that money can't buy happinessB. it is justified that money can't buy happinessC. it is authoritative that money can't buy happinessD. it is fair that money can't buy happiness2. We can infer that if one is very sad at some time in his life,_.A. he will be sad all his lifeB. he will never be happyC. he may be happy at other timeD. he may be influenced by the sadness all the time3. According to Ubel,_.A. money has much to do with happinessB. increases in money may make people happyC. money doesn't matter at allD. money has no effect on happiness4. Wealth does n't assure one of Ion g-term pleasure because.A. they don't know what to do with the moneyB. they are not good at using the moneyC. they gen erally expect more pleasure tha n money can bringD. they are not content with the wealth5. Lottery winners may not be happy —•A. if they quit their jobB. if they move to a sple ndid houseC. if they spe nd a lot of moneyD. if they are away from othersAnswer: CCBADPassage TwoTran spla nt surge ons work miracles. They take orga ns from one body and in tegrate them into ano ther, gran ti ng the lucky recipie nt a Ion ger, better life. Sadly, every year thousa nds of other people are less fortunate, dying while they wait for suitable organs to be found. The terrible con stra int on orga n tran spla ntati on is that every life exte nded depe nds on the death of some one young eno ugh and healthy eno ugh to have orga ns worth tran spla nting. Such donors are few. The wait ing lists are long, and gett ing Ion ger.Freedom from this con stra int is the dream of every tran spla nt surge on. So far attempts to make artificial organs have been disappointing: Nature is hard to mimic. Hence the renewed interest in trying to use organs from animals.Doctors in In dia have just announced that they have successfully tran spla nted a heart from a pig into a person. Pressure to in crease the nu mber of such "xe notran spla nts"（异种移植）seem to be grow in g. In Europe and America, herds of pigs are being specially bred and gen etically engin eered for organ donation. During 1996 at least two big reports on the subject-one in Europe and one in America- were published. They agreed that xenotransplantation was permissible on ethical gro un ds, and cautiously recomme nded they be allowed.The ethics of xen otra nspla ntatio n are relatively un worry ing. People already kill pigs both for food and for sport; killing them to save a human life seems, if anything, easier to justify. However, the scie nee of xenotran spla ntati on is much. less straightforward.Import an organ from one animal to another and you may bring with it any number of in fectious diseases. That much is well known. However, cop ing with this dan ger is not merely a matter of scree ning for obvious ills such as parasites. Many diseases that could harm huma ns may be both undetectable and harmless in their natural hosts. Diseases that have been dormant for years may suddenly become active if they find themselves in a new environment, such as a human recipie nt's body. After that, they may start to in fect other people.1. Despite tran spla nt surge ons' work, every year many people die because_.A. they are uni ucky patie ntsB. orga n tran spla ntati on is un reliableC. there are not eno ugh proper orga ns for tran spla ntati onD. few people are willi ng to don ate their orga ns after death2.

Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.Normally a student must attend a certain number of courses in order to graduate, and each course which he attends gives him a credit which he may count towards a degree. In many American universities the total work for a degree consists of thirty-six courses each lasting for one semester. A typical course consists of three classes per week for fifteen weeks; while attending a university a student will probably attend four or five courses during each semester. Normally a student would expect to take four years attending two semesters each year. It is possible to spread the period of work for the degree over a longer period. It is also possible for a student to move between one university and another during his degree course, though this is not in fact done as a regular practice. For every course that he follows a student is given a grade, which is recorded, and the record is available for the student to show to prospective employers. All this imposes a constant pressure and strain of work, but in spite of this some students still find time for great activity in student affairs. Elections to positions in student organizations arouse much enthusiasm. The effective work of maintaining discipline is usually performed by students who advise the academic authorities. Any student who is thought to have broken the rules, for example, by cheating has to appear before a student court. With the enormous numbers of students, the operation of the system does involve a certain amount of activity. A student who has held one of these positions of authority is much respected and it will be of benefit to him later in his career.1．Normally a student would attend at least______classes each week.A．36B．20C．12D．15正确答案：C解析：由文章第1段可知，每个学生每学期要上4到5门课，每门课每周有3节，由此可知学生每周要上12一15节课，因此一个学生每个星期至少要上12节课．故选C。

The latest British Social Attitudes survey shows just how widespread negative views of vulnerable groups in society are, but also makes clear that much of this shift in public opinion has been caused by current and previous government policies. So, should we expect better measures of child poverty as a result of the consultation? Not better for the children growing up in low-income families for sure.

(完整版)英语专业四级阅读理解模拟题(可编辑修改word版)

英语专业四级阅读理解模拟题A simple piece of rope hangs between some environmentally friendly Americans and their neighbors. On one side stand those who have begun to see clothes dryers as wasteful consumers of energy (up to 6% of total electricity) and powerful emitters of carbon dioxide (up to a ton of CO2 per household every year). As an alternative, they are turning to clotheslines as part of what Alexander Lee, an environmentalist, calls "what-I-can- do environmentalism."But on the other side are people who oppose air-drying laundry outside on aesthetic grounds. Increasingly, they have persuaded community and homeowners associations(HOAs) across the U.S. to ban outdoor clotheslines, which they say not only look unsightly but also lower surrounding property values. Those actions, in turn, have sparked a right-to-dry movement that is pressing for legislation to protect the choice to use clotheslines. Only three states--Florida, Hawaii and Utah--have laws written broadly enough to protect clotheslines. Right-to-dry advocates argue that there should be more.Matt Reck is the kind of eco-conscious guy who feeds his trees with bathwater and recycles condensation drops from his air conditioners to water plants. His family also uses a clothesline. But Otto Hagen, president of Reck's HOA in Wake Forest, N.C., notified him that a neighbor h, ad complained about his line. The Recks ignored the warning and still dry their clothes on a rope in the yard. "Many people claim to be environmentally friendly but don't take matters into their own hands," says Reck. HOAs Hagen has decided to hold off taking action. "I'm not going to go crazy," he says. "But if Matt keeps his line and more neighbors complain, I'll have to address it again."North Carolina lawmakers tried and failed earlier this year to insert language into an energy bill that would expressly prevent HOAs from regulating clotheslines. But the issue remains a touchy one with HOAs and real estate agents. "Most aesthetic restrictions are rooted, to a degree, in the belief that homogenous (统一协调的) exteriors are supportive of property value," says Sara Stubbins, executive director of the Community Association Institute's North Carolina chapter. In other words, associations worry that housing prices will fall if prospective buyers think their would-be neighbors are too poor to afford dryers.Alexander Lee dismisses the notion that clotheslines devalue property assets, advocating that the idea "needs to change in light of global warming." "We all have to do at least something to decrease our carbon footprint," Alexander Lee says.1.What is NOT mentioned as a disadvantage of using clothes dryers?A.Electricity consumption.B.Air pollution.C.Waste of energy.D.Ugly looking.2.Which of the following is INCORRECT?A.Opposers think air-drying laundry would devalue surrounding assets.B.Opposers consider the outdoor clothesline as an eyesore to the scenery.C.Right-to-dry movements led to the pass of written laws to protect clotheslines.D.Most of states in the US have no written laws to protect clotheslines.3.What is the HOAs' attitude towards the regulation of outdoor clotheslines?A.Concerned.B.Impartial.C.Supportive.D.Unclear.4.In the last paragraph Alexander Lee recommends thatA.clotheslines should be banned in the community.B.clotheslines wouldn't lessen the property values.C.the globe would become warmer and warmer.D.we should protect the environment in the community.5.An appropriate title for the passage might beA.Opinions on Environmental Protection.B.Opinions on Air-drying Laundry.C.What-I-Can-Do Environmentalism.D.Restrictions on Clotheslines.参考答案与解析：文章概要：本文探讨是否该用晾衣绳在室外晾晒衣服。

Early in the 1900s most American towns and cities had a Main Street. Main Street was always in the 1 of a town. This street was lined on the both sides with 2 businesses. Here, shoppers walked into stores to look at all sorts of merchandise: clothing, furniture, hardware, groceries. In addition, some shops offered 3 . These shops included drugstores, restaurants, shoe repair stores, and barber or hairdressing shops. But in the 1950s, a change began to 4 place. Too many automobiles had crowded into Main Street while too few parking places were 5 to shoppers. Because the streets were crowded, merchants began to look with interest at the open spaces outside the city limits. Open space is what their car driving customers 6 . And open space is what they got when the first shopping center was built. Shopping centers, or rather malls, 7 as a collection of small new stores away from crowded city centers. Attracted by hundreds of free parking space, customers were drawn away from 8 areas to outlying malls. And the growing 9 of shopping centers led in turn to the building of bigger and better stocked stores, By the late 1970s, many shopping malls had almost developed into small cities themselves. In addition to providing the 10 of one-stop shopping, malls were transformed into landscaped parks, with benches, fountains, and outdoor entertainment.A．designed B．take C．heart D．ne ededE．though F．convenience G．services H．fame I．various J．popularity K．cosmetics L．started M．downtown N．available O．cheapnessIn science, a theory is a reasonable explanation of observed events that are related. A theory often involves an imaginary model that helps scientists envision the way an observed event could be 11 . A good example of this is found in the kinetic molecular theory (分子运动论), in which gases are pictured as being made up of many small 12 that are in constant motion. A 13 theory, in addition to explaining past observations, helps to predict events that have not as yet been observed. After a theory has been 14 , scientists design experiments to test the theory. If observations do not 15 the predictions, the scientists must search 16 . There may be a fault in the experiment, or the theory may have to be revised or rejected. Science involves imagination and creative thinking as well as collecting information and performing experiments. Facts by themselves are notscience. As the mathematician Jules Henry Poincare said: "Science is 17 with facts just as a house is built with bricks, but a collection of facts cannot be called science any more than a pile of bricks can be called a house." Most scientists start an investigation by finding out what other scientists have learned about a particular problem. After known facts have been 18 , the scientist comes to the part of the investigation that requires 19 imagination. Possible solutions to the problem are formulated. These possible solutions are called hypotheses.In a way, any hypothesis is a leap into the unknown. It extends the scientist's thinking beyond the 20 facts. The scientist plans experiments, performs calculations, and makes observations to test hypotheses. For without hypotheses, further investigation lacks purpose and direction. When confirmed, they are incorporated into theories.A．nearly B．useful C．considerable D ．considerateE．published F．publicized G．gathered H ．producedI．built J．made K．known L．confirmM．particles N．parts O．furtherSection BDirections: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter.Preparing For Computer DisastersA．Fires, power surges, and floods, they're all facts of life. We read about them in the morning paper and see them on the evening news. We sympathize with the victims and commiserate (怜悯，同情) over their bad luck. We also shake our heads at the digital consequences—melted computers, system failures, destroyed data. Yet, somehow, many of us continue to live by that old mantra (祷文) of denial: "It won't happen to me." Well, the truth is, at some point you'll probably have to deal with at least one disaster. That's just how it goes, and in most aspects of our lives we do something about it. We buy insurance. We stow away provisions. We even make disaster plans and run drills. But for some reason, computer disaster recovery is a blind spot for many of us. It shouldn't be.B．Home computers contain some of our most important information, both business and personal, and making certain our data survives a disaster should be a priority. Moreover, even the smallest disaster can be a serious disruption. Personal computers have become an integral part of the smooth-running household. We use them to communicate, shop, and do homework, and they're even more vital to home office users. When home office computers go down, many small businesses grind to a halt. Fortunately, taking steps to recover from disasters and minimize their effects is quite straightforward. With a good offsite storage plan and the right tools, you can bounce back quickly and easily from minor computer disasters. And, should a majorcalamity strike, you can rest assured your data is safe.Offsite Storage: Major DisastersC．House fires and floods are among the most devastating causes of personal computer destruction. That's why a solid offsite backup and recovery plan is essential. Although many home users faithfully back up their hard drives, many would still lose all their data should their house flood or burn. That's because they keep their backups relatively close to their computers. Their backup disks might not be in the same room as their computers—tucked away in a closet or even the garage—but they're not nearly far enough away should a serious disaster strike. So, it's important to back up your system to a removable medium and to store it elsewhere.D．There are many ways to approach offsite storage. It starts with a choice of backup tools and storage medium. Disaster situations are stressful, and your recovery tools shouldn't add to that stress. They must be dependable and intuitive, making it easy to schedule regular backups and to retrieve files in a pinch. They must also be compatible with your choice of backup medium. Depending on your tools, you can back up to a variety of durable disk types—from CDs to Jazz drives to remote network servers. Although many of these storage media have high capacity, a backup tool with compression capabilities is a big plus, eliminating the inconvenience of multiple disks or large uploads.E．Once you select your tools and a suitable medium, you need to find a remote place to store your backups. The options are endless. However, no matter where you choose, be sure the site is secure, easily accessible, and a good distance away from your home. You may also want to consider using an Internet-based backup service. More and more service providers are offering storage space on their servers, and uploading files to a remote location has become an attractive alternative to conventional offsite storage. Of course, before using one of these services, make certain you completely trust the service provider and its security methods. Whatever you do, schedule backups regularly and store them far away from your home.Come What May: Handling the Garden Variety Computer CrisisF．Not all home computer damage results from physical disaster. Many less menacing problems can also hobble your PC or destroy your information. Systems crash, kids "rearrange" data, adults inadvertently delete files. Although these events might not seem calamitous, they can have serious implications. So, once again, it's important to be prepared. As with physical disasters, regular backups are essential. However, some of these smaller issues require a response that's more nuanced (有细微差别的) than wholesale backup and restoration. To deal with less-than-total disaster, your tool set must be both powerful and agile (敏捷的). For example, when a small number of files are compromised, you may want to retrieve those files alone. Meanwhile, if just your settings are affected, you'll want a simple way to roll back to your preferred setup. Yet, should your operating system fail, you'll need a way to boot your computer and perform large-scale recovery. Computer crises come in all shapes and sizes, and your backup and recovery tools must be flexible enough to meet each challenge.The Right Tools for the Right Job: Gearing up for DisasterG．When disaster strikes, the quality of your backup tools can make the difference between utter frustration and peace of mind. Symantec understands this and offers a range of top quality backup and recovery solutions. Norton GoBack is the perfect tool for random system crashes, failed installations, and inadvertent deletions. With this powerful and convenient solution, it's simple to retrieve overwritten files or to bring your system back to its pre-crash state. Norton Ghost is a time-tested home office solution. Equipped to handle full-scale backups, it's also handy for cloning hard drives and facilitating system upgrades. A favorite choice for IT professionals, it's the ideal tool for the burgeoning home office. You can buy Norton Ghost and Norton GoBack separately, or get them both when you purchase Norton System Works.H．Life's disasters, large and small, often catch us by surprise. However, with a little planning and the right tools, you can reduce those disasters to bumps in the road. So, don't wait another day. Buy a good set of disaster recovery tools, set up an automatic backup schedule, and perform a dry run every now and again. Then, rest easy.21、You should prepare for your computer disasters now and again.22、The backup and recovery tools must be flexible enough to deal with various computer crises.23、For some reason, computer disaster recovery is always ignored by many of us.24、The most devastating causes of personal computer destruction includes house fires and floods.25、You should find a distant place to store your backups after selecting your tools and a suitable medium.26、You can bounce back quickly and easily minor computer disasters with the help of a good offsite storage plan and the right tools.27、Not only physical disaster can damage your computer.28、It's necessary for us to back up our systems to some transferable medium and to put it somewhere else.29、The quality of your backup tools determines whether you are frustrated or have a peaceful mind when disaster strikes.30、You should take steps to recover from computer disasters so as to minimize their effects.Paper—More Than Meets The EyeA．We are surrounded by so much paper and card that it is easy to forget just how complex it is. There are many varieties and grades of paper materials, and whilst it is fairly easy to spot the varieties, it is far more difficult to spot the grades. It needs to be understood that most paper and card is manufactured for a specific purpose, so that whilst the corn-flake packet may look smart, it is clearly not something destined for the archives. It is made to look good, but only needs a limited life span. It is also much cheaper to manufacture than high grade card.B．Paper can be made from an almost endless variety of cellulose (纤维)-based material which will include many woods, cottons and grasses, of whichpapyrus is an example and from where we get the word "paper". Many of these are very specialized, but the preponderance of paper making has been from soft wood and cotton or rags, with the bulk being wood-based.Paper from WoodC．In order to make wood into paper it needs to be broken down into fine strands. Firstly by powerful machinery and then boiled with strong alkalies (碱) such as caustic soda, until a fine pulp of cellulose fibers is produced. It is from this pulp that the final product is made, relying on the bonding together of the cellulose into layers. That, in a very small nutshell is the essence of paper making from wood. However, the reality is rather more complicated. In order to give us our white paper and card, the makers will add bleach and other materials such as china clay and additional chemicals.D．A further problem with wood is that it contains a material that is not cellulose, something called lignin (木质素). This is essential for the tree since it holds the cellulose fibers together, but if it is incorporated into the manufactured paper it presents archivists (档案员) with a problem. Lignin eventually breaks down and releases acid products into the paper. This will weaken the bond between the cellulose fibers and the paper will become brittle and look rather brown and careworn. We have all seen this in old newspapers and cheap paperback books. It has been estimated that most paper back books will have a life of not greater than fifty years. Not what we need for our archives.E．Since the lignin can be removed from the paper pulp during manufacture, the obvious question is "why is it left in the paper?" The answer lies in the fact that lignin makes up a considerable part of the tree. By leaving the lignin in the pulp a papermaker can increase his paper yield from a tree to some 95%. Removing it means a yield of only 35%. It is clearly uneconomic to remove the lignin for many paper and card applications.F．It also means, of course, that lignin-free paper is going to be more expensive, but that is nevertheless what the archivist must look for in his supplies. There is no point whatsoever in carefully placing our valuable artifacts in paper or card that is going to hasten their demise. Acid (酸) is particularly harmful to photographic materials, causing them to fade and in some cases simply vanish!G．So, how do we tell a piece of suitable paper or card from one that is unsuitable? You cannot do it by simply looking, and rather disappointingly, you cannot always rely on the label. "Acid-free" might be true inasmuch as a test on the paper may indicate that it is a neutral material at this time. But lignin can take years before it starts the inevitable process of breaking down, and in the right conditions it will speed up enormously.H．Added to this, as I have indicated earlier, paper may also contain other materials added during manufacture such as bleach, china clay, chemical whiteners and size. This looks like a bleak picture, and it would be but for the fact that there are suppliers who will guarantee the material that they sell. If you want to be absolutely sure that you are storing in, or printing on, the correct material then this is probably the only way. Incidentally, acids can migrate from material to material. Lining oldshoe boxes with good quality acid-free paper will do little to guard the contents. The acid will get there in the end.Paper from RagI．Paper is also commonly made from cotton and rag waste. This has the advantage of being lignin-free, but because there is much less cotton and rag than trees, it also tends to be much more expensive than wood pulp paper. You will still need to purchase from a reliable source though, since even rag paper and card can contain undesirable additives. A reliable source for quality rag papers is a recognized art stockist. Many water color artists insist on using only fine quality rag paper and board.J．The main lesson to learn from this information is that you cannot rely on purchasing archival materials from the high street. The only safe solution is to purchase from specialist suppliers. It may cost rather more, but in the end you will know that your important and valuable data and images have the best home possible.31、During the whole manufacturing process, the final product is made from a pulp of cellulose fibers.32、The corn-flake packet is cheaper than high grade card.33、There are a lot of materials which can be used for making paper, but the superiority ones are soft wood, cotton and rags.34、Although free of lignin, paper made from cotton and rag waste can also cost more money than wood pulp paper because there is much less cotton and rag than trees.35、Lignin is essential for the tree but it will make paper easy to break.36、Many paper producers will preserve lignin during manufacture, because leaving the lignin will make more paper from a tree.37、In order to make white paper and card, the makers will add bleach.38、Acid is particularly harmful to photographic materials.39、What we can learn from "Paper from Rag" is that you had better buy archival materials from specialist suppliers.40、The lignin is commonly not removed from the paper, as the ligin-free paper will be more expensive.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneThe fridge is considered a necessity. It has been so since the 1960s when packaged food first appeared with the label: "store in the refrigerator."In my fridgeless fifties childhood, I was fed well and healthily. The milkman came daily, the grocer, the butcher, the baker, and the ice-cream man delivered two or three times a week. The Sunday meat would last until Wednesday and surplus bread and milk became all kinds of cakes. Nothing was wasted, and we were nevertroubled 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. A vast way of 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 globe 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 wealthy 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 insignificant. If you don't believe me, try it yourself, invest in a food cabinet and turn off your fridge next winter. You may miss the hamburger, but at least you'll get rid of that terrible hum.41、The statement "In my fridgeless fifties childhood, I was fed well and healthily." (Para. 2) suggests that ______.A．the author was well-fed and healthy even without a fridge in his fiftiesB．the author was not accustomed to using fridges even in his fiftiesC．the fridge was in its early stage of development in the 1950sD．there was no fridge in the author's home in the 1950s42、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．People had effective ways to preserve their food.D．Food was sold fresh and did not get rotten easily.43、Who benefited the least from fridges according to the author?A．Inventors. B．Manufacturers.C．Consumers. D．Traveling salesmen.44、Which of the following phrases in the fourth paragraph indicates the fridge's negative effect on the environment?A．With mild temperatures. B．Climatically almost unnecessary.C．Artificially-cooled space. D．Hum away continuously.45、What is the author's overall attitude toward fridges?A．Critical. B．Objective.C．Neutral. D．Compromising.I'm usually fairly skeptical about any research that concludes that people are either happier or unhappier or more or less certain of themselves than they were 50 years ago. While any of these statements might be true, they are practically impossible to prove scientifically. Still, I was struck by a report which concluded thattoday's children are significantly more anxious than children in the 1950s. In fact, the analysis showed, normal children ages 9 to 17 exhibit a higher level of anxiety today than children who were treated for mental illness 50 years ago.Why are America's kids so stressed? The report cites two main causes: increasing physical isolation—brought on by high divorce rates and less involvement in community, among other things—and a growing perception that the world is a more dangerous place.Given that we can't turn the clock back, adults can still do plenty to help the next generation cope.At the top of the list is nurturing (培育) a better appreciation of the limits of individualism. No child is an island. Strengthening social ties helps build communities and protect individuals against stress.To help kids build stronger connections with others, you can pull the plug on TVs and computers. Your family will thank you later. They will have more time for face-to-face relationships, and they will get more sleep.Limit the amount of virtual (虚拟的) violence your children are exposed to. It's not just video games and movies; children see a lot of murder and crime on the local news.Keep your expectations for your children reasonable. Many highly successful people never attended Harvard or Yale.Make exercise part of your daily routine. It will help you cope with your own anxieties and provide a good model for your kids. Sometimes anxiety is unavoidable. But it doesn't have to ruin your life.46、The author thinks that the conclusions of any research about people's state of mind are ______.A．surprising B．confusingC．illogical D．questionable47、What does the author mean when he says, "we can't turn the clock back" (Para. 3)?A．It's impossible to slow down the pace of change.B．The social reality children are facing cannot be changed.C．Lessons learned from the past should not be forgotten.D．It's impossible to forget the past.48、According to an analysis, compared with normal children today, children treated as mentally ill 50 years ago ______.A．were less isolated physically B．were probably less serf-centeredC．probably suffered less from anxiety D．were considered less individualistic49、The first and most important thing parents should do to help their children is ______.A．to provide them with a safer environmentB．to lower their expectations for themC．to get them more involved sociallyD．to set a good model for them to follow50、What conclusion can be drawn from the passage?A．Anxiety, though unavoidable, can be coped with.B．Children's anxiety has been enormously exaggerated.C．Children's anxiety can be eliminated with more parental care.D．Anxiety, if properly controlled, may help children become mature.Passage TwoFood can be divided into two basic categories: real food and pleasure food. Real food is fuel for the body's needs, while pleasure food, which is high in fat and sugar, is primarily for taste satisfaction. The categories are pretty obvious. Broccoli (西兰花) is real food. Cookies are in the pleasure group.When you are hungry, you are faced with choices. If you aren't suffering from excessive hunger, you can be rational about them. Go to the refrigerator. What looks good? If you have chosen a real food, say, a turkey sandwich, you can be certain your body can use it for fuel. Eat it and enjoy.Two hours later you are hungry again. Back to the refrigerator. What looks good? Ice cream. Stop! Employ your will power just a little. Ice cream is not what your body needs. Does something else look good? Yes, a piece of toast with peanut butter and a glass of milk sound good too. Okay, go ahead, remembering that high-fat real foods should be eaten in moderation.One trick is to eliminate pleasure foods from your kitchen. Instead, keep a variety of high-quality foods available at all times. In short, buy lots of delicious real food, food you really like, and get rid of the junk.But what if you have ice cream on hand and nothing sounds good? Although you don't want to eat pleasure food whenever the urge strikes, there is a legitimate place for them in your diet. If you have analyzed your feelings and there are no other needs imitating hunger, eat the ice cream. You have not failed. On the contrary, you have accepted your natural appetite, but not blindly.Surprisingly, when you know you can eat anything you want, and that you never have to put up with unsatisfied hunger again, it takes a lot of pressure off. You will begin to want to eat what your body needs, and your body will begin to need foods that will lead to slimness.51、Which of the following statements is NOT true?A．The author is against getting rid of pleasure food altogether.B．One can eat the high-fat real foods heartily since it is fuel for the body.C．Make sure to keep pleasure food such as ice cream in your diet.D．Of course you can sometimes have ice cream if you really want to.52、What would be the best title for this passage?A．Real Food And Pleasure Food.B．Reducing Weight.C．Limit Your Consumption Of Pleasure Food.D．How To Choose Food When You Are Hungry.53、What can you assume from the last paragraph?A．Being able to eat anything doesn't necessarily imply pleasure.B．Real foods may lead to slimness.C．Eat only what your body needs.D．Be sure to satisfy your hunger whenever it strikes you.54、What can real food be except ______.A．ice cream B．cauliflowerC．a turkey sandwich D．a piece of toast55、Judging from the fourth paragraph, what does "junk" mean?A．Food like ice cream. B．Food you do not like.C．Pleasure foods. D．Low-quality foods.Researchers have established that when people are mentally engaged, biochemical changes occur in the brain that allow it to act more effectively in cognitive areas such as attention and memory. This is true regardless of age.People will be alert and receptive if they are faced with information that gets them to think about things they are interested in. And someone with a history of doing more rather than less will go into old age more cognitively sound than someone who has not had an active mind.Many experts are so convinced of the benefits of challenging the brain that they are putting the theory to work in their own lives. "The idea is not necessarily to learn to memorize enormous amounts of information," says James Fozard, associate director of the National Institute on Aging. "Most of us don't need that kind of skill. Such specific training is of less interest than being able to maintain mental alertness." Fozard and others say they challenge their brains with different mental skills, both because they enjoy them and because they are sure that their range of activities will help the way their brains work.Gene Cohen, acting director of the same institute, suggests that people in their old age should engage in mental and physical activities individually as well as in groups. Cohen says that we are frequently advised to keep physically active as we age, but older people need to keep mentally active as well. Those who do are more likely to maintain their intellectual abilities and to be generally happier and better adjusted. "The point is, you need to do both," Cohen says. "Intellectual activity actually influences brain-cell health and size."56、People who are cognitively healthy are those ______.A．whose minds are alert and receptiveB．who are highly intelligentC．who can remember large amounts of informationD．who are good at recognizing different sounds57、According to Fozard's argument, people can make their brains work more efficiently by ______.A．constantly doing memory workB．making frequent adjustmentsC．going through specific trainingD．taking part in various mental activities58、The findings of James Fozard and other scientists in their work ______.A．remain a theory to be further proved。

大学英语四级阅读模拟题及答案阅读1空调的危害Although many of us may feel air-conditioners bring relief from hot,humid or polluted outside air,they pose many potential health hazards.Much research has looked at how the movement of air inside a closed environment---such as an office building---can spread disease or expose people in the building to harmful chemicals.One of the more widely publicized dangers is that of Legionnaire’s disease,which was first recognized inthe1970s.This was found to have affected people in buildings with air-conditioning systems in which warmair pumped out of the system’cooling towers was somehow sucked back into the air intake(通风口),in mostcases due to poor design.The warm air,filled with bacteria,was combined with cooled,conditioned air andwas then circulated around various parts of the building. Studies showed that even people outside such buildings were at risk if they walked past air exhaust pipes.Large air-conditioning systems add water to the air they circulate by means of humidifiers(湿度调节器).Inolder systems,the water used for this process is kept in special reservoirs,the bottoms of which providebreeding grounds for bacteria which can find their way into the ventilation (通风)system.The risk to human health from this situation has been highlighted by the fact that the immune systems(免疫系统)of approximately half of workers in air-conditioned office buildings have developed the ability to fight off the organisms found at the bottom of system reservoirs. But chemicals called“biocides”are added to reservoirs to make them germ-free,and they are dangerous in their own right in sufficient quantities,as they often contain compounds strongly linked to cancers.Finally,it should be pointed out that the artificial climatic environment created byair-conditioners canalso affect us.In a natural environment,whether indoor or outdoor,there are small variations in temperature and humidity.Indeed,the human body has long been accustomed to these normal changes.In an air-conditioned living or working environment,however,body temperatures remain well under37℃,our normal temperature.This leads to a weakened immune system and thus greater exposure to diseases such as colds and flu.练习题：Choose correct answers to the question:1.What do we know about Legionnaire's disease from the passage?A.It was the most widely concerned office hazard.B.It can affect people both inside and outside the building.C.It happens only in air-conditioned office buildings.D.It does not develop in well-designed buildings.2.In the old air-conditioned systems,bacteria first develop______.A.in the reservoirsB.in the ventilation systemc.in the humidifiersD.in the air intake3.The fact that about half of workers developed the ability to fight off the bacteria may__.A.relieve people’s worry about the danger caused by the bacteriaB.help people find an effective way to get rid of the bacteriaC.reflect the serious danger brought by the bacteriaD.cause serious disease such as cancers to people4.The author most probably wants the readers to treat biocides with an attitude of_.A.cautionB.trustC.enthusiasmD.criticism5.The last paragraph implies that our immune system can be weakened when_•A.we live in an artificial climatic environmentB.there are variations in temperature and humidityC.our body temperatures often remain not high enoughD.we are often exposed to diseases such as colds and flu答案解析：1.[B]事实细节题。

英语四级考试阅读模拟题(一)Where do pesticides fit into the picture of environmental disease? We have seen that they now pollute soil,water and food, that they have the power to make our streams fishless and our gardens and woodlands silent and birdless. Man, however much he may like to pretend the contrary, is part of nature. Can he escape a pollution that is now so thoroughly distributed throughout our world: We know that even single exposures to these chemicals, if the amount is large enough, can cause extremely severe poisoning. But this is not the major problem. The sudden illness or death of farmers, farmworkers, and others exposed to sufficient quantities of pesticides is very sad and should not occur. For the population as a whole, we must be more concerned with the delayed effects of absorbing small amounts of the pesticides that invisibly pollute our world.Responsible public health officials have pointed out that the biological effects of chemicals are cumulative over long periods of time, and that the danger to individual may depend on the sum of the exposures received throughout his lifetime. For these veryreasons the danger is easily ignored. It is human nature to shake off what may seem to us a threat of future disaster. Men are naturally most impressed by diseases which have obvious signs, says a wise physician, Dr Rene Dubos, yet some of their worst enemies slowly approach them unnoticed.练习题：Choose correct answers to the question:1.Which of the following is closest in meaning to the sentence Manis part of nature (Para. 1, Lines 3-4)?A. Man appears indifferent to what happens in nature.B. Man acts as if he does not belong to nature.C. Man can avoid the effects of environmental pollution.D. Man can escape his responsibilities for environmental effects of pesticides?2. What is the authors attitude toward the environmental effects of pesticides?A. PessimisticB. IndifferentC. DefensiveD. Concerned3. In the authors view, the sudden death caused by exposure to large amounts of pesticides _____.A. is not the worst of the negative consequences resulting from the use of pesticidesB. now occurs most frequently among all accidental deathsC. has sharply increased so as to become the center of public attentionD. is unavoidable because people cant do without pesticides in farming4. People tend to ignore the delayed effects of exposure to chemical because _____.A. limited exposure to them does little harm to peoples healthB. the present is more important for them than the futureC. the danger does not become apparent immediatelyD. humans are capable of withstanding small amounts of poisoning5. It can be concluded from Dr. Dubos remarks that _____.A. people find invisible diseases difficult to deal withB. attacks by hidden enemies tend to be fatalC. diseases with obvious signs are easy to cureD. people tend to overlook hidden dangers caused by pesticides英语四级考试阅读模拟题答案1.[B] 题干的句子是文章第1段第3句，这是一个带有插入语的简洁句，contrary在此表示跟part of nature相反，因此答案为B。

英语四级阅读理解模拟试题附答案

英语四级阅读理解模拟试题附答案英语四级阅读理解模拟试题：【原文】There are two factors which determine an individuals intelligence. The first is the sort of brain he is born with. Human brains differ considerably , some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual— the sort of environment in which he is brought up. If an individual is handicapped(不利) environmentally, 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 individuals intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. 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(抚养) homes. Peter was raised by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the 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 environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Marks I. Q. was 125, twenty-five points higherthan the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.英语四级阅读理解模拟试题：【题目】21. This selection can best be titled____________.A.

PART V READING COMPREHENSION [25 MIN]In this section there are four passages followed by questions or unfinished statements, each with four suggested answers marked A, B, C and D. Choose the one that you think is the best answer.TEXT AWe can begin our discussion of "population as global issue" with what most persons mean when they discuss "the population problem": too many people on earth and a too rapid increase in the number added each year. The facts are not in dispute, It was quite right to employ the analogy that likened demographic growth to "a long, thin powder fuse that burns steadily and haltingly until it finally reaches the charge and explodes."To understand the current situation, which is characterized by rapid increases in population, it is necessary to understand the history of population trends. Rapid growth is a comparatively recent phenomenon. Looking back at the 8,000 years of demographic history, we find that populations have been virtually stable or growing very slightly for most of human history. For most of our ancestors, life was hard, often nasty, and very short. There was high fertility in most places, but this was usually balanced by high mortality. For most of human history, it was seldom the case that one in ten persons would live past forty, while infancy and childhood were especially risky periods. Often, societies were in clear danger of extinction because death rates could exceed their birthrates. Thus, the population problem throughout most of history was how to prevent extinction of the human race.This pattern is important to notice. Not only does it put the current problems of demographic growth into a historical perspective, but it suggests that the cause of rapid increase in population in recent years is not a sudden enthusiasm for more children, but an improvement in the conditions that traditionally have caused high mortality.Demographic history can be divided into two major periods: a time of long, slow growth which extended from about 8,000 BC.till approximately AD. 1650. In the first period of some 9600 years, the population increased from some 8 million to 500 million in 1650. Between 1650 and the present, the population has increased from 500 million to more than 4 billion. And it is estimated that by the year 2000 there will be 6.2 billion people throughout the world. One way to appreciate this dramatic difference in such abstract numbers is to reduce the time frame to something that is more manageable. Between 8000BC and 1650, an average of only 50,000 persons was being added annually to the world's population each year. At present, this number is added every six hours. The increase is about 80,000,000 persons annually.1.Which of the following demographic growth pattern is most suitable for the long thin powder fuse analogy?A.A virtually stable or slightly decreasing period and then a sudden explosion of population.B.A slow growth for a long time and then a period of rapid, dramatic increase.C.Too many people on earth and a few rapid increase in the number added each year.D.A long period when death rates exceeds birthrates and then a short period with higher fertility and lowermortality.2.During the first period of demographic history, societies were often in danger of extinction because___.A.only one in ten persons could live past 40.B.there was higher mortality than fertility in most places.C.it was too dangerous to have babies due to the poor conditions.D.our ancestors had little enthusiasm for more children.3.Which statement is true about population increase?A.There might be an increase of 2.2 billion persons from now to the year 2000.B.About 50,000 babies are born every six hours at present.C.Between 8000 BC and the present, the population increase is about 80,000,000 persons each year.D.The population increased faster between 8000BC and 1650 than between 1650 and the present.4.The author of the passage intends to___.A.warn people against the population explosion in the near future.pare the demographic growth pattern in the past with that after 1650.C.find out the cause for rapid increase in population in recent years.D.present us a clear and complete picture of the demographic growth.5.The word "demographic" in the first paragraph means___.A.statistics of human.B.surroundings study.C.accumulation of human.D.development of human.TEXT BChinese Americans today have higher incomes than Americans in general and higher occupational status. The Chinese have risen to this position despite some of the harshest discrimination and violence faced by any immigrants to the United States in the history of this country. Long confined to a narrow range of occupations they succeeded in those occupations and then spread out into other areas in later years, when opportunities finally opened up for them. Today much of the Chinese prosperity is due to the simple fact that they work more and have more (usually better) education than others. Almost one out of five Chinese families has three or more income earners compared to one out of thirteen for Puerto Ricans, one out of ten among American Indians, and one out of eight among Whites. When the Chinese advantages in working and educational are held constant, they have no advantage over other Americans. That is in a Chinese Family with a given number of people working and with a given amount of education by the head of the family, the income is not only about average for such families, and offer a little less than average.While Chinese Americans as a group are prosperous and well-educated Chinatowns are pockets of poverty, and illiteracy is much higher among the Chinese than among Americans in general. Those paradoxes are due to sharp internal differences. Descendants of the Chinese Americans who emigrated long ago from Toishan Province have maintained Chinese values and have added acculturation to American society with remarkable success. More recent Hong Kong Chinese are from more diverse cultural origins, and acquired western values and styles in Hong Kong, without having acquired the skills to proper and support those aspirations in the American economy. Foreign-born Chinese men in the United States are one-fourth lower incomes than native-born Chinese even though the foreign-born have been in the United States an average of seventeen years. While the older Hong Kong Chinese work tenaciously to sustain and advance themselves, the Hong Kong Chinese youths often react with resentment and antisocial behavior, including terrorism and murder. The need to maintain tourism in Chinatown causes the Chinese leaders to mute or downplay these problems as much as possible.6.According to the passage, today, Chinese Americans owe their prosperity to___.A.their diligence and better education than others.B.their support of American government.C.their fight against discriminations.D.advantages in working only.7.The passage is mainly concerned with___.A.chinese Americans today.B.social status of Chinese Americans today.C.incomes and occupational status of Chinese Americans today.D.problems of Chinese Americans today.8.Chinatowns are pockets of poverty, as is probably associated with___.A.most descendants of Chinese Americans are rebelling.B.most descendants of Chinese Americans are illiterate.C.sharp internal difference between Chinese coming from different cultural backgrounds.D.only a few Chinese Americans are rich.9.Which of the following statements is not true according to this articleA.As part of the minority, Chinese Americans are still experiencing discrimination in American today.B.Nowadays, Chinese Americans are working in wider fields.C.Foreign-born Chinese earn lower income than native-born Chinese Americans with the similar advantagesin the U.S.D.None of the above.10.According to the author, which of the following can best describe the older Hong Kong Chinese and theyoungerA.Tenacious; rebellion.B.Conservative; open-minded.C.Out-of-date; fashionable.D.Obedient; disobedient.TEXT CA controversy erupted in the scientific community in early 1998 over the use of DNA (deoxyribonucleic acid ) fingerprinting in criminal investigations. DNA fingerprinting was introduced in 1987 as a method to identify individuals based on a pattern seen in their DNA, the molecule of which genes are made. DNA is present in every cell of the body except red blood cells. DNA fingerprinting has been used successfully in various ways, such as to determine paternity where it is not clear who the father of a particular child is. However, it is in the area of criminal investigations that DNA fingerprinting has potentially powerful and controversial uses.DNA fingerprinting and other DNA analysis techniques have revolutionized criminal investigations by giving investigators powerful new tools in the attempt to trove guilt, not just establish innocence. When used in criminal investigations, a DNA fingerprint pattern from a suspect is compared with a DNA fingerprint pattern obtained from such material as hairs or blood found at the scene of a crime. A match between the two DNA samples can be used as evidence to convict a suspect.The controversy in 1998 stemmed form a report published in December 1991 by population geneticists Richard C. Lewontin of Harvard University in Cambridge, Mass., and Daniel L. Hartl called into question the methods to calculate how likely it is that a match between two DNA fingerprints might occur by chance alone. In particular, they argued that the current method cannot properly determine the likelihood that two DNA samples will match because they came from the same individual rather than simply from two different individuals who are members of the same ethnic group. Lewontin and Hartl called for better surveys of DNA patterns methods are adequate.In response to their criticisms, population geneticists Ranajit Chakraborty of the University of Texas in Dallas and Kenneth K.Kidd of Yale University in New Haven, Conn., argued that enough data are already available to show that the methods currently being used are adequate. In January 1998, however, the federal Bureau of Investigation and laboratories that conduct DNA tests announced that they would collect additional DNA samples form various ethnic groups in an attempt to resolve some of these questions. And, in April, a National Academy of Sciences called for strict standards and system of accreditation for DNA testing laboratories.11.efore DNA fingerprinting is used, suspects____.A.would have to leave their fingerprints for further investigationsB.would have to submit evidence for their innocenceC.could easily escape conviction of guiltD.cold be convicted of guilt as well12.DNA fingerprinting can be unreliable when ____.A.the methods used for blood- cell calculation are not accurateB.two different individuals of the same ethnic group may have the same DNA fingerprinting patternC.a match is by chance left with fingerprints that happen to belong to two different individualsD.two different individuals leave two DNA samples.13.To geneticists like Lewontin and Hartl, the current method ____.A.is not so convincing as to exclude the likelihood that two DNA samples can never come from twoindividualsB.is arguable because two individuals of the same ethnic group are likely to have the same DNA pattern.C.Is not based on adequate scientific theory of geneticsD.Is theoretically contradictory to what they have been studying14.The attitude of the Federal Bereau of Investigation shows that ____.A.enough data are yet to be collected form various ethnic groups to confirm the unlikelihood of two DNAsamples coming from two individual membersB.enough data of DNA samples should be collected to confirm that only DNA samples form the same personcan matchC.enough data are yet to be collected from various ethnic groups to determine the likelihood of two differentDNA samples coming form the same personD.additional samples from various ethnic groups should be collected to determine that two DNA samples areunlikely to come from the same person15.National Academy of Sciences holds the stance that ____.A.DNA testing should be systematizedB.Only authorized laboratories can conduct DNA testingC.The academy only is authorized to work out standards for testingD.The academy has the right to accredit laboratories for DNA testingTEXT DMost of us are taught to pay attention to what is said—the words. Words do provide us with some information, but meanings are derived from so many other sources that it would hinder our effectiveness as a partner to a relationship to rely too heavily on words alone. Words are used to describe only a small part of the many ideas we associate with any given message. Sometimes we can gain insight into some of those associations if we listen for more than words. We don't always say what we mean or mean what we say. Sometimes our words don't mean anything except " I'm letting off some steam. I don't really want you to pay close attention to what I'm saying. Just pay attention to what I'm feeling." Mostly we mean several things at once. A person wanting to purchase a house says to the current owner, "This step has to be fixed before I'll buy." The owner says, " It's been like that for years." Actually, the step hasn't been like that for years, but the unspoken message is: " I don't want to fix it. We put up with it. Why can't you?" The search for a more expansive view of meaning can be developed of examining a message in terms of who said it, when it occurred, the related conditions or situation, and how it was said.When a message occurs can also reveal associated meaning. Let us assume two couples do exactly the same amount of kissing and arguing. But one couple always kisses after an argument and the other couple always argues after a kiss. The ordering of the behaviors may mean a great deal more than the frequency of the behavior.A friend's unusually docile behavior may only be understood by noting that it was preceded by situations that required an abnormal amount of assertiveness. Some responses may be directly linked to a developing pattern of responses and defy logic. For example, a person who says "No!" to a serials of charges like "You're dumb," "You're lazy," and "You're dishonest," may also say "No!" and try to justify his or her response if the next statement is "And you're good looking."We would do well to listen for how messages are presented. The words, "If sure has been nice to have you over," can be said with emphasis and excitement or ritualistically. The phrase can be said once or repeated several times. And the meanings we associate with the phrase will change accordingly. Sometimes if we say something infrequently it assumes more importance; sometimes the more we say something the less importance it assumes.16.Effective communication is rendered possible between two conversing partners, if ___.A.they use proper words to carry their ideas.B.they both speak truly of their own feelings.C.they try to understand each other's ideas beyond words.D.they are capable of associating meaning with their words.17."I'm letting off some steam" in paragraph 1 means___.A.I'm just calling your attention.B.I'm just kidding.C.I'm just saying the opposite.D.I'm just giving off some sound.18.The house-owner's example shows that he actually means___.A.the step has been like that for years.B.he doesn't think it necessary to fix the step.C.the condition of the step is only a minor fault.D.the cost involved in the fixing should be shared.19.Some responses and behaviors may appear very illogical, but are justifiable if___.A.linked to an abnormal amount of assertiveness.B.seen as one's habitual pattern of behavior.C.taken as part of an ordering sequence.D.expressed to a series of charges.20.The word "ritualistically" in the last paragraph equals something done___.A.without true intention.B.light-heartedly.C.in a way of ceremony.D.with less emphasis.答案： 1-5 ABADA 6-10 ACCCA 11-15 CBABB 16-20 DBABC。

国内的各类英语考试中几乎都有阅读理解题型，高校英语四级考试也不例外。

高校英语四级阅读理解试题是试卷中分值最重的题型，为了提高大家的阅读水平，下面是我为大家带来英语四级阅读理解模拟练习及答案详解，盼望对大家的学习有所关心!Directions:There are 2 passages in this section.Each passage is followed by some questions or unfinished statements.For each of them there are four choices marked A),B),C) and D) .You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 57 to 61 are based on the following passage.There is a new type of small advertisement becoming increasingly common in newspaper classified columns. It is sometimes placed among "situations vacant', although it does not offer anyone a job, and sometimes it appears among "situations wanted', although it is not placed by someone looking for a job, either. What it does is to offer help in applying for a job."Contact us before writing your application', or "Make use of our long experience in preparing your curriculum vitae or job history', is how it is usually expressed. The growth and apparentsuccess of such a specialized service is, of course, a reflection on the current high levels of unemployment. It is also an indication of the growing importance of the curriculum vitae (or job history), with the suggestion that it may now qualify as an art form in its own right.There was a time when job seekers simply wrote letters of application. "Just put down your name, address, age and whether you have passed any exams', was about the average level of advice offered to young people applying for their first jobs when I left school. The letter was really just for openers, it was explained, everything else could and should be saved for the interview. And in those days of full employment the technique worked. The letter proved that you could write and were available for work. Your eager face and intelligent replies did the rest.Later, as you moved up the ladder, something slightly more sophisticated was called for. The advice then was to put something in the letter which would distinguish you from the rest. It might be the aggressive approach. "Your search is over. I am the person you are looking for', was a widely used trick that occasionally succeeded. Or it might be some special feature specially designed for the job interview.There is no doubt, however, that it is increasing number ofapplicants with university education at all points in the process of engaging staff that has led to the greater importance of the curriculum vitae.57. The new type of advertisement which is appearing in newspaper columns .A) informs job hunters of the opportunities availableB) promises to offer useful advice to those looking for employmentC) divides available jobs into various typesD) informs employers of the people available for work58. Nowadays a demand for this specialized type of service has been created because .A) there is a lack of jobs available for artistic peopleB) there are so many top?level jobs availableC) there are so many people out of workD) the job history is considered to be a work of art59. In the past it was expected that first job hunters would .A) write an initial letter giving their life historyB) pass some exams before applying for a jobC) have no qualifications other than being able to read and writeD) keep any detailed information until they obtained aninterview60. Later, as one went on to apply for more important jobs, one was advised to include in the letter .A) something that would distinguish one from other applicantsB) hinted information about the personality of the applicantC) ones advantages over others in applying for the jobD) an occasional trick with the aggressive approach61. The curriculum vitae has become such an important document because .A) there has been an increase in the number of jobs advertisedB) there has been an increase in the number of applicants with degreesC) jobs are becoming much more complicated nowadaysD) the other processes of applying for jobs are more complicatedPassage TwoQuestions 62 to 66 are based on the following passage.In cities with rent control, the city government sets the maximum rent that a landlord can charge for an apartment. Supporters of rent control argue that it protects people who are living in apartments. Their rent cannot increase; therefore, they are not in danger of losing their homes. However, the critics say that aftera long time, rent control may have negative effects. Landlords know that they cannot increase their profits. Therefore, they invest in other businesses where they can increase their profits. They do not invest in new buildings which would also be rentcontrolled. As a result, new apartments are not built. Many people who need apartments cannot find any. According to the critics, the end result of rent control is a shortage of apartments in the city.Some theorists argue that the minimum wage law can cause problems in the same way. The federal government sets the minimum that an employer must pay workers. The minimum helps people who generally look for unskilled, lowpaying jobs. However, if the minimum is high, employers may hire fewer workers. They will replace workers with machinery. The price, which is the wage that employers must pay, increases. Therefore, other things being equal, the number of workers that employers want decreases. Thus, critics claim, an increase in the minimum wage may cause unemployment. Some poor people may find themselves without jobs instead of with jobs at the minimum wage.Supporters of the minimum wage say that it helps people keep their dignity. Because of the law, workers cannot sell their services for less than the minimum. Furthermore, employers cannot force workers to accept jobs at unfair wages.Economic theory predicts the results of economic decisions such as decisions about farm production, rent control, and the minimum wage. The predictions may be correct only if "other things are equal'. Economists do not agree on some of the predictions. They also do not agree on the value of different decisions. Some economists support a particular decision while others criticize it. Economists do agree, however, that there are no simple answers to economic questions.62. There is the possibility that setting maximum rent may .A) cause a shortage of apartmentsB) worry those who rent apartments as homesC) increase the profits of landlordsD) encourage landlords to invest in building apartment63. According to the critics, rent control .A) will always benefit those who rent apartmentsB) is unnecessaryC) will bring negative effects in the long runD) is necessary under all circumstances64. The problem of unemployment will arise .A) if the minimum wage is set too highB) if the minimum wage is set too lowC) if the workers are unskilledD) if the maximum wage is set65. The passage tells us .A) the relationship between supply and demandB) the possible results of government controlsC) the necessity of government controlD) the urgency of getting rid of government controls66. Which of the following statements is NOT true?A) The results of economic decisions can not always be predicted.B) Minimum wage can not always protect employees.C) Economic theory can predict the results of economic decisions if other factors are not changing.D) Economic decisions should not be based on economic theory.答案详解：57.

Each choice in the bank is identified by a letter. You may not use any of the words in the bank more than once.The anthropologist (人类学家) Clifford Geertz defines culture as a "historically transmitted pattern of meanings embodied in symbols... by 1 of which men can communicate, perpetuate and develop their own knowledge about and attitudes towards life."Why is it important that you 2 about other cultures?

Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter.Lost For WordsA．In the Native American Navajo nation, which sprawls across four states in the American south-west, the native language is dying. Most of its speakers are middle-aged or elderly. Although many students take classes in Navajo, the schools are run in English. Street signs, supermarket goods and even their own newspaper are all in English. Not surprisingly, linguists doubt that any native speakers of Navajo will remain in a hundred years' time.B．Navajo is far from alone. Half the world's 6,800 languages are likely to vanish within two generations—that's one language lost every ten days. Never before has the planet's linguistic diversity shrunk at such a pace. "At the moment, we are heading for about three or four languages dominating the world", says Mark Pagel, an evolutionary biologist at the University of Reading. "It's a mass extinction, and whether we will ever rebound (回弹) from the lost is difficult to know."C．Isolation breeds linguistic diversity: as a result, the world is peppered with languages spoken by only a few people. Only 250 languages have more than a million speaker, and at least 3,000 have fewer than 2,500. It is not necessarily these small languages that are about to disappear. Navajo is considered endangered despitehaving 150,000 speakers. What makes a language endangered is not just the number of speakers, but how old they are. If it is spoken by children it is relatively safe. The critically endangered languages are those that are only spoken by the elderly, according to Michael Krauss, director of the Alassk Native Language Center, in Fairbanks.D．Why do people reject the language of their parents? It begins with a crisis of confidence, when a small community finds itself alongside a larger, wealthier society, says Nicholas Ostler, of Britain's Foundation for Endangered Languages, in Bath. "People lose faith in their culture," he says, "When the next generation reaches their teens, they might not want to be induced into the old traditions."E．The change is not always voluntary. Quite often, governments try to kill off a minority language by banning its use in public or discouraging its use in school, all to promote national unity. The former US policy of running Indian reservation in English, for example, effectively put languages such as Navajo on the danger list. But Salikoko Mufwene, who chairs the Linguistics Department at the University of Chicago, argues that the deadliest weapon is not government policy but economic globalization. "Native Americans have not lost pride in their language, but they have had to adapt to socio-economic pressures," he says, "They can not refuse to speak English if most commercial activity is in English." But are languages worth saving? At the very least, there is a loss of data for the study of languages and their evolution, which relies on comparisons between languages, both living and dead. When an unwritten and unrecorded language disappears, it is lost to science.F．Language is also intimately bond up with culture, so it may be difficult to preserve one without the other. "If a person shifts from Navajo to English, he loses something," Mufwene says. "Moreover, the loss of diversity may also deprive us of different ways of looking at the world," says Pagel. There is mounting evidence that learning a language produces physiological changes in brain. "Your brain and mine are different from the brain of someone who speaks French, for instance," Pagel says, and this could affect our thoughts and perceptions. "The patterns and connections we make among various concepts may be structured by the linguistic habits of our community."G．So despite linguists' best efforts, many languages will disappear over the next century. But a growing interest in cultural identity may prevent the direst predictions from coming true. "The key to fostering diversity is for people to learn their ancestral tongue, as well as the dominant language, says Doug Whalen, founder and president of the Endangered Language Fund in New Haven, Connecticut. "Most of these languages will not survive without a large degree of bilingualism," he says. In New Zealand, classes for children have slowed the erosion of Maori and rekindled interest in the language. A similar approach in Hawaii has produced about 8,000 new speakers of Polynesian languages in the past few years. In California, "apprentice" programs have provided life support to several indigenous languages. Volunteer "apprentices" pair up with one of the last living speakers of a Native American tongue to learn a traditional skill such as basket weaving, with instruction exclusively in the endangered language. After about 300 hours of training they are generallysufficiently fluent to transmit the language to the next generation. But Mufwene says that preventing a language dying out is not the same as giving it new life by using it every day. "Preserving a language is more like preserving fruits in a jar," he says.H．However, preservation can bring a language back from the dead. There are examples of languages that have survived in written form and then been revived by later generations. But a written form is essential for this, so the mere possibility of revival has led many speakers of endangered languages to develop systems of writing where none existed before.21、The great variety of languages came about mainly as a result of geographical isolation.22、Governments try to kill off a minority language because they want to promote national unity.23、Some speakers of endangered languages have produced writing systems in order to help secure the survival of their mother tongue.24、At present the linguistic diversity in the world is shrinking at a high speed.25、Endangered languages cannot be saved unless people learn to speak more than one language.26、A written form is essential for the dying language.27、Native Americans have to speak English when most commercial activity is conducted in English.28、People reject the language of their parents because of a crisis of confidence.29、The Navajo language will die out because most of its speakers are middle-aged or elderly.30、The way we think may be determined by our language.Play Is A Serious BusinessA．Playing is a serious business. Children engrossed (吸引) in a make-believe world, fox cubs play-fighting or kittens teasing a ball of string aren't just having fun. Play may look like a carefree and exuberant way to pass the time before the hard work of adulthood comes along, but there's much more to it than that. For a start, play can even cost animals their lives. Eighty per cent of deaths among juvenile fur seals occur because playing pups fail to spot predators (掠夺者，食肉动物) approaching. It is also extremely expensive in terms of energy. Playful young animals use around two or three per cent of energy cavorting (洗脑), and in children that figure can be closer to fifteen per cent. "Even two or three per cent is huge," says John Byers of Idaho University. "You just don't find animals wasting energy like that," he adds. There must be a reason.B．But if play is not simply a developmental hiccup (打嗝), as biologists once thought, why did it evolve? The latest idea suggests that play has evolved to build big brains. In other words, playing makes you intelligent. Playfulness, it seems, is common only among mammals, although a few of the larger-brained birds also indulge. Animals at play often use unique signs—tail-wagging in dogs, for example—to indicate that activity superficially resembling adult behavior is not really in earnest.A popular explanation of play has been that it helps juveniles develop the skills theywill need to hunt, mate and socialize as adults. Another has been that it allows young animals to get in shape for adult life by improving their respiratory endurance. Both these ideas have been questioned in recent years.C．Take the exercise theory. If play evolved to build muscle or as a kind of endurance training, then you would expect to see permanent benefits. But Byers points out that the benefits of increased exercise disappear rapidly after training stops, so many improvement in endurance resulting from juvenile play would be lost by adulthood. "If the function of play was to get into shape," says Byers, "the optimum time for playing would depend on when it was most advantageous for the young of a particular species to do so. But it doesn't work like that." Across species, play tends to peak about halfway through the suckling stage and then decline.D．Then there's the skills-training hypothesis. At first glance, playing animals do appear to be practicing the complex maneuvers they will need in adulthood. But a closer inspection reveals this interpretation as too simplistic. In one study, behavioral ecologist Tim Caro, from the University of California, looked at the predatory play of kittens and their predatory behavior when they reached adulthood. He found that the way the cats played had no significant effect on their hunting prowess in later life.E．Earlier this year, Sergio Pellis of Lethbridge University, Canada, reported that there is a strong positive link between brain size and playfulness among mammals in general. Comparing measurements for fifteen orders of mammals, he and his team found large brains (for a given body size) are linked to greater playfulness. The converse was also found to be true. Robert Barton of Durham University believes that, because large brains are more sensitive to developmental stimuli than smaller brains, they require more play to help mould them for adulthood. "I concluded it's to do with learning, and with the importance of environmental data to the brain during development," he says.F．According to Byers, the timing of the playful stage in young animals provides an important clue to what's going on. If you plot the amount of time juvenile devotes to play each day over the course of its development, you discover a pattern typically associated with a "sensitive period"—a brief development window during which the brain can actually be modified in ways that are not possible earlier or later in life. Think of the relative ease with which young children—but not infants or adults—absorb language. Other researchers have found that play in cats, rats and mice is at its most intense just as this "window of opportunity" reaches its peak.G．"People have not paid enough attention to the amount of the brain activated by plays," says Marc Bekoff from Colorado University. Bekoff studied coyote (山狗) pups at play and found that the kind of behavior involved was markedly more variable and unpredictable than that of adults. Such behavior activates many different parts of the brain, he reasons. Bekoff likens it to a behavioral kaleidoscope (万花筒), with animals at play jumping rapidly between activities. "They use behavior from a lot of different contexts—predation, aggression, reproduction," he says. "Their developing brain is getting all sorts of stimulation."H．Not only is more of the brain involved in play than was suspected, but italso seems to activate higher cognitive processes. "There's enormous cognitive involvement in play," says Bekoff. He points out that play often involves complex assessments of playmates, ideas of reciprocity (互惠) and the use of specialized signals and rules. He believes that play creates a brain that has greater behavioral flexibility and improved potential for learning later in life. The idea is backed up by the work of Stephen Siviy of Gettysburg College. Siviy studied how bouts of play affected the brain's levels of a particular chemical associated with the stimulation and growth of nerve cells. He was surprised by the extent of the activation. "Play just lights everything up," he says. By allowing link-ups between brain areas that might not normally communicate with each other, play may enhance creativity.I．What might further experimentation suggest about the way children are raised in many societies today? We already know that rat pups that denied the chance to play grow smaller brain components and fail to develop the ability to apply social rules when they interact with their peers. With schooling beginning earlier and becoming increasingly exam-orientated, play is likely to get even less of a look-in. Who knows what the result of that will be?31、Tim Caro found that the way the cats played had no significant influence upon their hunting prowess in later life.32、People have not paid enough attention to the intelligence activated by play.33、Children use about fifteen percent of their energy cavorting.34、A "sensitive period" refers to a brief period during which the brain can actually be modified in ways that are not possible earlier or later in life.35、By linking up the brain areas that might not normally communicate with each other, play may increase creativity.36、Byers points out that play is not a kind of fitness training for the future.37、The latest idea shows that play has developed to build big brains.38、Not only is more of the brain involved in play than was suspected, but it also seems to activate higher cognitive process.39、With schooling beginning earlier and becoming more and more exam-orientated, play is likely to play a less important role in brain development.40、Earlier this year, Sergio Pellis reported that there is a strong positive connection between brain size and playfulness among mammals in general.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OnePlay is the principal business of childhood, and more and more in recent year's research has shown the vital importance of play in the development of a human being. From earliest infancy, every child needs adequate opportunity and the right material for play, and the main tools of play are toys. Their main function is to suggest, encourage and assist play. To succeed in this they must be good toys, therefore it is important to choose suitable toys for different stages of a child'sdevelopment.In recent years research on infant development has shown the standard a child is likely to reach, within the range of his inherited abilities, is largely determined in the first three years of his life. Therefore a baby's ability to profit from the right play materials should be things to touch, things to listen to; things to watch. At no time in his life will a child develop as fast as now; in the first two years each month brings a change in what he can do and what he needs. A baby who is encouraged and stimulated, talked to, and shown things and played with, has the best chance of growing up successfully. There is no doubt that the right play materials and opportunities are of the utmost importance.The next stage, from three to five years old, is the heyday (全盛期) for toys, and at this stage curiosity knows no bounds. Every type of suitable toy should be made available to the child; bricks and jigsaws (拼版玩具) and construction toys; painting and making things; sand and water play; toys for imaginative and pretending play. Children of this age are concerned and serious when they play, for to them play is a serious business, and through it they are learning about the world and growing up.By the third stage of play development from five to seven or eight years the child is at school. But for a few more years play is still the best way of learning, at home or at school. The right toy at this stage can sometimes lead to the choice of a career.Until the age of seven or eight, play and work mean much the same thing to a child. But once reading has been mastered, then books and school become the main source of learning. Toys are still interesting and valuable, but their significance has changed to a child of nine or ten years, toys and games mean, as to adults, relaxation and fun.41、From the passage we understand that a child ______.A．tends to be interested in toysB．matures through play over and overC．cannot mature without toysD．has to be taught how to play42、In the writer's opinion the right kind of play materials for infants ______.A．stimulate the talentsB．encourage visual awarenessC．develop the touching senseD．assist the aural responses43、Children of three to five years old find play a serious business because they ______.A．are developing their musclesB．are exercising their imaginationC．are acquiring knowledge through playD．are learning how to grow up44、Once a child has learned to read, he usually ______.A．stops playing with toysB．learns less from his toysC．only gets information from booksD．only learns when at school45、It seems that older children and adults consider toys and games should ______.A．be played as a jokeB．be played for amusementC．teach the players to learn somethingD．make the players feel funnySurprisingly, no one knows how many children receive education in English hospitals, still less the content or quality of that education. Proper records are just not kept. We know that more than 850 000 children go through hospital each year, and that every child of school age has a legal right to continue to receive education while in hospital.Little wonder the latest survey concludes that the extent and type of hospital teaching available differ a great deal across the country. It is found that half of the hospitals in England which admit children have no teacher. A further quarter has only a part-time teacher. The special children's hospitals in major cities do best; general hospitals on the country and holiday areas are worst off. From this survey, one can estimate that fewer than one in five children have some contact with a hospital teacher and that contact may be as little as two hours a day. Most children interviewed were surprised to find a teacher in hospital at all. They had not been prepared for it by parents or their own school. If there was a teacher they were much more likely to read books and do math or number work; without a teacher they would only play games.Reasons for hospital teaching range from preventing a child falling behind and maintaining the habit of school to keeping a child occupied, and the latter is often all the teacher can do. The position and influence of many teachers was summed up when parents referred to them as "the library lady" or just "the helper". Children tend to rely on intimate school friends to keep in touch with school work. Once back at school, children rarely get extra teaching, and are told to catch up as best as they can.Many short-stay child-patients catch up quickly. But schools do very little to ease the anxiety about falling behind expressed by many of the children interviewed.46、Which of the following statements is true?A．Every child in hospital receives some teaching.B．Not enough is known about hospital teaching.C．Hospital teaching is of poor quality.D．The special children's hospitals are worst off.47、It can be inferred from the latest survey that ______.A．hospital teaching across the country is similarB．each hospital has at least one part-time teacherC．all hospitals surveyed offer education to childrenD．only one-fourth of the hospital have full-time teacher48、The hospital teachers are found ______.A．not welcomed by the children and their parentsB．unnecessaryC．not quite helpfulD．capable49、In order to catch up with their school work, children in hospital usually turn to ______.A．hospital teachers B．schoolmatesC．parents D．school teachers50、We can conclude from the passage that the author is ______.A．unfavorable towards children receiving education in hospitalsB．in favor of the present state of teaching in hospitalsC．unsatisfied with the present state of hospital teachingD．satisfied with the results of the latest surveyPassage TwoFrom good reading we can derive pleasure, companionship, experience, and instruction. A good book may absorb our attention so completely that for the time being we forget our surroundings and even our identity. Reading good books is one of the greatest pleasures in life. It increases our contentment when we are cheerful, and lessens our troubles when we are sad. Whatever may be our main purpose in reading, our contact with good books should never fail to give us enjoyment and satisfaction.With a good book in our hands we need never be lonely. Whether the characters portrayed are taken from real life or are purely imaginary, they may become our companions and friends. In the pages of books we can walk with the wise and the good of all lands and all times. The people we meet in books may delight us either because they resemble human friends whom we hold dear or because they present unfamiliar types whom we are glad to welcome as new acquaintances. Our human friends sometimes may bore us, but the friends we make in books need never weary us with their company. By turning the page we can dismiss them without any fear of hurting their feelings. When human friends desert us, good books are always ready to give us friendship, sympathy, and encouragement.One of the most valuable gifts bestowed by books is experience. Few of us can travel far from home or have a wide range of experiences, but all of us can lead varied lives through the pages of books. Whether we wish to escape from the seemingly dull realities of everyday life or whether we long to visit some far-off place, a book will help us when nothing else can. To travel by book we need no bank account to pay our way; no airship or ocean liner or stream-lined train to transport us; no passport to enter the land of our heart's desire. Through books we may get the thrill of hazardous adventure without danger. We can climb lofty mountains, brave the perils of an Antarctic winter, or cross the scorching sands of the desert, all without hardship. In books we may visit the studios of Hollywood; we may mingle with the gay throngs of the Paris boulevards; we may join the picturesque peasantsin an Alpine village or the kindly natives on a South Sea island. Indeed, through books the whole world is ours for the asking. The possibilities of our literary experiences are almost unlimited. The beauties of nature, the enjoyment of music, the treasures of art, the triumphs of architecture, the marvels of engineering, are all open to the wonder and enjoyment of those who read.51、Why is it that we sometimes forget our surroundings and even our identity while reading?A．No one has come to disturb you.B．Everything is so quiet and calm around you.C．The book you are reading is so interesting and attractive.D．Your book is overdue; you are finishing it at a very fast speed.52、How would you account for the fact that people like their acquaintances in books even more?A．They resemble human friends exactly.B．They are unfamiliar types we like.C．They never desert us.D．They never hurt our feelings.53、Which of the following is NOT true?A．All of us can lead varied lives through the pages of books.B．We can travel free of charge to our heart's content by reading books.C．We should rely on reading to escape from the seemingly dull realities of everyday life.D．We may obtain valuable experience from reading good books.54、The word "weary" (Para. 2) means ______.A．"to attract someone's attention"B．"to distract someone's attention"C．"to make someone very tired"D．"to make someone interested"55、"... the whole world is ours for the asking" (Para. 2) implies that ______.A．in books the world is more accessible to usB．we can ask to go anywhere in the worldC．we can make a claim to everything in this worldD．we can make a round-the-world trip free of chargeThe poverty line is the minimum income that people need for an acceptable standard of living. People with incomes below the poverty line are considered poor. Economists study the causes of poverty in order to find solutions to the problem.As the general standard of living in the country rises, the poverty line does, too. Therefore, even with today's relatively high standard of living, about 10 percent of the people in the United States are below the poverty line. However, if these people had stable jobs, they could have an acceptable standard of living. Economists suggest several reasons why poor people do not have jobs.For one thing, more than half of the poor people in the United States are not qualified to work. Over 40 percent of the poor people are children. By law, children less than 16 years old cannot work in many industries. A large number of poor。

英语四级快速阅读专项练习(含答案解析)（一）Skimming and ScanningDirections: In this part, you will have 15 minutes to go over the passage quickly and answer the questions on Answer Sheet 1. For questions 1-7, choose the best answer from the four choices marked [A], [B], [C] and [D]. For question 8-10, complete the sentences with the information given in the passage.Animals on the MoveIt looked like a scene from “Jaws”but without the dramatic music. A huge shark was slowly swimming through the water, its tail swinging back and forth like the pendulum of a clock.Suddenly sensitive nerve ending in the shark’s skin picked up vibrations of a struggling fish. The shark was immediately transformed into a deadly, efficient machine of death. With muscles taut, the shark knifed through the water at a rapid speed. In a flash the shark caught its victim, a large fish, in its powerful jaws. Then, jerking its head back and forth, the shark tore huge chunks of flesh from its victim and swallowed them. Soon the action was over.Moving to SurviveIn pursuing its prey, the shark demonstrated in a dramatic way the important role of movement, or locomotion, in animals.Like the shark, most animals use movement to find food. They also use locomotion to escape enemies, find a mate, and explore new territories. The methods of locomotion include crawling, hopping, slithering, flying, swimming, or walking.Humans have the added advantage of using their various inventions to move about in just about any kind of environment. Automobiles, rockets, and submarines transport humans from deep oceans to as far away as the moon. However, for other animals movement came about naturally through millions of years of evolution. One of the most successful examples of animal locomotion is that of the shark. Its ability to quickly zero in on its prey has always impressed scientists. But it took a detailed study by Duke University marine biologists S. A. Wainwright, F. Vosburgh, and J. H. Hebrank to find out how the sharks did it. In their study the scientists observed sharks swimming in a tank at Marine land in Saint Augustine, Fla. Movies were taken of the sharks’movements and analyzed. Studies were also made of shark skin and muscle.Skin Is the KeyThe biologists discovered that the skin of the shark is the key to the animal’s high efficiency in swimming through the water. The skin contains many fibers that crisscross like the inside of a belted radial tire. The fibers are called collagen fibers. These fibers can either store or release large amounts of energy depending on whether the fibers are relaxed or taut. When the fibers are stretched, energy is stored in them the way energy is stored in the string of a bow when pulled tight. When the energy is released, the fibers become relaxed.The Duke University biologists have found that the greatest stretching occurs where the shark bends its body while swimming. During the body’s back and forth motion, fibers along the outside part of the bending body stretch greatly. Much potential energy is stored in the fibers. This energy is released when the shark’s body snaps back the other way.As energy is alternately stored and released on both sides of the animal’s body, the tailwhips strongly back and forth. This whip-like action propels the animal through the water like a living bullet.Source of EnergyWhat causes the fibers to store so much energy? In finding the answer the Duke University scientists learned that the shark’s similarity to a belted radial tire doesn’t stop with the skin. Just as a radial tire is inflated by pressure, so, too, is the area just under the shark’s collagen “radials”. Instead of air pressure, however, the pressure in the shark may be due to the force of the blood pressing on the collagen fibers.When the shark swims slowly, the pressure on the fibers is relatively low. The fibers are more relaxed, and the shark is able to bend its body at sharp angles. The animal swims this way when looking around for food or just swimming. However, when the shark detects an important food source, some fantastic involuntary changes take place.The pressure inside the animal may increase by 10 times. This pressure change greatly stretches the fibers, enabling much energy to be stored.This energy is then transferred to the tail, and the shark is off. The rest of the story is predictable.Dolphin Has Speed RecordAnother fast marine animal is the dolphin. This seagoing mammal has been clocked at speeds of 32 kilometers (20 miles) an hour. Biologists studying the dolphin have discovered that, like the shark, the animal’s efficient locomotion can be traced to its skin. A dolphin’s skin is made up in such a way that it offers very little resistance to the water flowing over it. Normally when a fish or other object moves slowly through the water, the water flows smoothly past the body. This smooth flow is known as laminar flow. However, at faster speeds the water becomes more turbulent along the moving fish. This turbulence muses friction and slows the fish down.In a dolphin the skin is so flexible that it bends and yields to the waviness of the water. The waves, in effect, become tucked into the skin’s folds. This allows the rest of the water to move smoothly by in a laminar flow. Where other animals would be slowed by turbulent water at rapid speeds, the dolphin can race through the water at record breaking speeds.Other Animals Less EfficientNot all animals move as efficiently as sharks and dolphins. Perhaps the greatest loser in locomotion efficiency is the slug. The slug, which looks like a snail without a shell, lays down a slimy trail over which it crawls. It uses so much energy producing the slimy mucus and crawling over it that a mouse traveling the same distance uses only one twelfth as much energy.Scientists say that because of the slug’s inefficient use of energy, its lifestyle must be restricted. That is, the animals are forced to confine themselves to small areas for obtaining food and finding proper living conditions. Have humans ever been faced with this kind of problem?1.According to the passage, a shark can use movement to do something except____________.[A]to find food[B]to avoid being chased by its enemies[C]to find a new place to live[D]to show its braveness2.Examples of automobiles, rockets and submarines are used to show that _______________.[A]humans are the most clever living creatures in the world[B]human inventions enable us to travel in almost any kind of environment[C]humans are very successful in inventing transportation tools[D]humans can’t move like other animals in any circumstances3.What is the key to the shark’s swift locomotion in water?[A]The skin. [B]The tail. [C]The muscle. [D]The jaw.4.According to the Duke University scientists, when does the shark stretch its collagen fibers to the greatest extent?[A]When moving its tail rapidly.[B]When finding its preys.[C]When staying without any movement.[D]When bending its body in swimming.5.Why is the area just under the shark’s collagen fibers similar to a belted radial tire?[A]Because it is also full of blood pressure.[B]Because it is also filled of air pressure.[C]Because it is also inflated by pressure.[D]Because it also can be used again and again.6.A laminar flow is formed when a fish swims________________.[A]slowly through the water[B]rapidly through the water[C]against the current[D]at the fastest speed in water7.Consuming the equal amount of energy as a slug does, a mouse can travel _________ as long as a slug.[A]one twelfth times[B]the same[C]12 times[D]1.2 times8.A shark finds its prey by________________.9.According to the passage, _______________can be compared to the string of a bow for both of them store energy when stretched.10.When the shark detects an important food source, _______________________take place.（二）Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions on Answer Sheet 1.

They also hope their children learn to read quickly and easily, so that they’re ready for the demands put on them by school and the world.Kids want to learn how to read, but they also crave entertainment, whether it’s quiet and passive or dynamic and interactive. The aims of the Story Reader line of electronic books are to entertain children and to introduce them to the processof learning how to read in a gentle and enjoyable way. In this article, we’ll show you how Story Reader works and if it accomplishes that goal.Story Reader is a compact, roughly 12-inch-by-12-inch plastic case (with a carrying handle ) that opens to reveal an actual book that fits snugly into the Reader itself. Story Reader’s core feature is that it "reads" the book aloud to a child as he follows along. The child turns the pages when prompted by the Story Reader or at his own pace.Books have both text and illustrations. The electronic book responds to the child’s wishes. The Story Reader speaks the text for the current page. If the child turns back a few pages, the Reader recognizes that page and reads it again. Kids react well to this interactivity because it instills a sense of cuntrol over the story.There are Three Story Reader ProductsThe basic Story Reader, introduced in 2003, is as described above and is intended for kids three years of age and older.Each book has a small companion cartridge that slides into a port on the case and contains the audio encoded into its memory for the story.The device has a volume control but no on/off switch--a deliberate choice so kids can simply open it up and begin reading. It takes four AAA batteries (or operates on household current with an optional adaptor) and retails for around $20.Find out more information about the more than 60 titles at the Story Reader website.Early in 2006, Publications International, Ltd.--Story Reader’s publisher--introduced My First Story Reader, designed for newborns to kids up to age three. As with the original, a narrator reads the story aloud, this time from a 12-page book made from a heavier paperstock that includes sound effects and music to enliven the experience.My First Story Reader features two play modes, one with narration, the other that asks questions about the images on each page. The child can press any of three buttons to answer basic questions about shapes and colors. The last two pages ofeach My First Story Reader book features a sing-along rhyming melody. My First Story Reader retails for about $20.Late in 2006, Publications International introduced a video version of Story Reader called Story Reader Video Plus for kids up to the age of seven. Retailing for about $35, it combines a stand-alone Story Reader with an "Animated Story Mode"that plays through your television and includes a "Learning Game Mode".The Animated Story Mode works just as it sounds--when you connect it to your television through color-coded cables, the story appears on screen and changes as your child turns the pages. Kids get to the Learning Game Mode by turning to thelast page of the book. There, they can choose from five educational games. While it depends on the story, generally there are pattern games, memory games, and platform games. Similar to Nintendo games like Super Mario Brothers, in a platform game the child uses the included controller to guide him through the environment and conquer obstacles.Story Reader Video Plus isn’t a video game, technically, and Publications International bills the Story Reader line more as electronic books than toys. This reassures many parents, and it’s why Story Reader is sold in bookstores and in the book section of major retailers.What about the Educational Underpinnings of Story Reader?Studies show an alarming decline in reading rates among all age groups in America, especially among the young.Children are bombarded on a daily basis with multiple forms of entertainment that compete with traditional learning.Kids naturally emulate the adults in their lives, and seeing their parents and other family members enjoy reading is a powerful motivator. Establishing and keeping a Read-At-Home Night helps families spend time together and helps form lifelong reading habits in children.Here’s how you do it:·Set aside one night a week in your household and call it "Read-At-Home Hour"--or anything you prefer. Establish a time allotment that works for your family, for example, 30 minutes or an hour.·Minimize interruptions from the TV, computer, and video games--and turn on the telephone answering machine.·Choose one book for the entire family to read aloud together, or encourage individual family members to choose their own books to read quietly. Electronic books can work in this context, as well.·Finally, sit down, relax, and read.1. The aims of the Story Reader line of electronic books are __[A] to entertain and teach children[B] to play with the child[C] to ease the parents’burden[D] to ease the teachers’burden2. Story Reader’s key characteristic is that __[A] it "reads" the book which the child likes[B] it "reads" the book while the child plays[C] it "reads" the book while the child follows along[D] it "reads" the book while the parent works3. Children __ are suitable users of the basic Story Reader.[A] up to six months old[B] up to age one[C] up to age two[D] up to age three4. The basic Story Reader for sale is about __[A] 12 dollars[B] 20 dollars[C] 35 dollars[D] 60 dollars5. My First Story Reader is characteristic with[A] two play modes[B] three play modes[C] four play modes[D] five play modes6. Story Reader Video Plus is a video version of Story Reader designed for __[A] newborns to kids up to age three[B] newborns to kids up to age seven[C] children up to the age of five[D] children up to the age of seven7. How many games can children choose from the Animated Story Mode?[A] four[B] five[C] six[D] seven8.

For questions 1-7, choose the best answer from the four choices marked [A], [B], [ C ]and [D]. For questions 8-10, complete the sentences with the information given in the passage.The Right Amount of EnergyWe all enjoy being around people with energy. They inspire us. They are stimulating, fun, and uplifting. An energetic person has passion in his voice, a bounce in his step, and a smile on his face. Energy makes a person likable, and likability is akey ingredient in persuasive communications. Many business professionals underestimate the energy level required to generate enthusiasm among their listeners. But electrifying speakers bring it. They have an energy that is several levels higher than the people they are attempting to influence.Most business professionals could use an energy boost for public speaking situations such as Webinars, podcasts, staff meetings, conference calls, and television and radio interviews. Each of these opportunities requires a higher level of energythan would normally be appropriate if you were just chatting to someone in the hallway. But how do you project the right level of vigor without seeming over the top? By weighing yourself on an energy scale. And on this scale, more is better.The Energy ScaleRecently I helped an executive prepare for his first major presentation in his new role."Tell me where your energy is right now on a scale of one to ten," I asked. "One being fast asleep and ten being Jim Cramer on Mad Money. You know, the guy who’s yelling and gesturing wildly on his CNBC show. Where are you now?""A three," the speaker replied."OK, what would it feel like to be a seven, eight or nine? Give it a try," I suggested.If they’re being honest, most presenters place themselves at a three to six on the energy scale. That means there is plenty of room to boost your energy while not appearing too zany. But keep in mind, once you hit a ten or higher, you could be the next YouTube (GOOG) hit--which is not necessarily your top objective! Here are several surefire strategies to boost your energy presence.1. Practice leaving your comfort zone.Record several minutes of your presentation as you would normally deliver it: Play it back, preferably with someone else watching and listening as well. Ask yourself and the observer, where am I on the energy scale? Now try it again. This time,break out of your comfort zone. Ham it up. Raise your voice. Use big gestures. Put a big smile on your face. Get to a point where you would feel slightly awkward and uncomfortable. Now watch it. Most likely your energy level will be far more engaging and still remain appropriate fur the situation.2. Smile and have fun.Why do most people seem to enjoy Virgin entrepreneur Richard Branson? Because the guy has fun and it shows. He always has a warm, engaging smile on his face. Of course, you can argue that it’s easy to walk around with a smile when you’re worth $4 billion! But seriously, smile. Itwon’t hurt and it will make you more likable. Most business professionals don’t smile as much as they should during presentations. I’m helping some executives prepare for CES, the big Consumer Electronics Show in January where they will announce new products. They get so caught up in the slides and what they’re going to say ( as they should during preparation ), they forget that new products bring joy to their consumers. In most cases--with the exception of bad news, of course--the first and last thing you say to yourself before launching into your presentation should be, "Have3. Get your body moving.Many people are uncomfortable using expansive hand gestures. Don’t be. I spoke to David McNeill at the University of Chicago, who is known for his research into gesture and speech. He says that clear, confident speakers use hand gestures and that the gestures leave a positive impression on listeners.He went on to say that using gestures will help you speak better because for most of us it takes effort not to use gestures.Don’t be afraid of using your hands.AOL’s (TWX) is one of my favorite video search engines. I use it to retrieve clips of business speakers to study their body language. Symantec’s (SYMC) John Thompson, Oracle’s (ORCL) Larry Ellison, Cisco’s (CSCO) John Chambers, and eBay’s (EBAY) Meg Whitman are excellent examples of people with confident, energetic body language.4. Study TV and radio personalities.Stars of television and radio who score high on the likability scale have high-energy personalities. I had a conversation with Suze Orman over the phone a couple of years ago and remember it to this day. Her energy comes right through the speaker. What you see on her CNBC show is what you get behind the scenes. High energy. The other day I watched Food Network (SSP) star Rachael Ray sign books at a mall where I happened to be shopping. Sometimes critics poke fun at her"perky" personality and phrases like "yum-o," but the fact is she has energy and millions of viewers enjoy it. The networkmorning-show hosts are typically chosen for their energetic personalities. Today’s Matt Lauer on NBC (GE) and The EarlyShow’s Julie Chen on CBS (CBS) are excellent examples, but there are many others on morning television.Remember, maintaining an energetic presence is very difficult to do unless you’re involved with something you enjoy. If you are truly passionate about your company, product, or service, then show it. Speak with energy and vitality. Your listenerswill love you for it.l. From the first paragraph, what is a key point in persuasive communication?[A] Stimulation.[B] Uplitting.[C] Fun.[D] Likability.2. Have an energy several levels higher than the people they are attempting to influence.[A] Electrifying speakers[B] Business professionals[C] Und.vnamic persons[D] Listeners3.

The scale of the energy is[A] seven, eight or nine[B] ten or higher[C] three to six[D] one to ten5. What does the example mean in the third paragraph?[A] There is little room to boost your energy while not appeanng too zany.[B] There is a little room to boost your energy while not appearing too zany.[C] There is much room to boost your energy while not appearing too zany.[D] There is no room to boost your energy while not appearing too zany.6. Why is Virgin entrepreneur Richard Branson popular?[A] Because he has fun and it shows.[B] Because he doesn’t smile as much as he should during presentations.[C] Because he is very humorous.[D] Because he is famous.7.

Maintaining an energetic presence is very difficult to do unless__________（四）The EarthPower and LightCompared to the rest of the universe, the Earth is very small. Our planet and seven others orbit the Sun, which is only one of about 200 billion stars in our galaxy. Our galaxy, the Milky Way, is part of the universe, which includes millions of othergalaxies and their stars and planets. By comparison, the Earth is microscopic.Compared to a person, on the other hand, the Earth is enormous. It has a diameter of 7,926 miles ( 12,756 kilometers) at the equator, and it has a mass of about 6 x 1024 kilograms. The Earth orbits the Sun at a speed of about 66,638 miles per hour (29.79 kilometers per second). Don’t dwell on those numbers too long, though; to a lot of people, the Earth is inconceivably, mind-bogglingly big. And it’s just a fraction of the size of the Sun.From our perspective on Earth, the Sun looks very small. This is because it’s about 93 million miles away from us. The Sun’s diameter at its equator is about 100 times bigger than Earth’s, and about a million Earths could fit inside the Sun. TheSun is inconceivably, mind-bogglingly bigger.But without the Sun, the Earth could not exist. In a sense, the Earth is a giant machine, full of moving parts and complex systems. All those systems need power, and that power comes from the Sun.The Sun is an enormous nuclear power source--through complex reactions, it transforms hydrogen into helium, releasing light and heat. Because of these reactions, every square meter of our planet’s surface gets about 342 Watts of energy from the Sun every year. This is about 1.7 ~ 1017 Watts total, or as much as 1.7 billion large power plants could generate. You can learn about how the Sun creates energy in How the Sun Works.When this energy reaches the Earth, it provides power for a variety of reactions, cycles and systems. It drives the circulation of the atmosphere and the oceans. It makes food for plants, which many people and animals eat. Life on Earth could not exist without the Sun, and the planet itself would not have developed without it.To a casual observer, the Sun’s most visible contributions to life are light, heat and weather.Night and DaySome of the Sun’s biggest impacts on our planet are also its most obvious. As the Earth spins on its axis, parts of the planet are in the Sun while others are in the shade. In other words, the Sun appears to rise and set. The parts of the world that are in daylight get warmer while the parts that are dark gradually lose the heat they absorbed during the day.You can get a sense of how much the Sun affects the Earth’s temperature by standing outside on a partly cloudy day.When the Sun is behind a cloud, you feel noticeably cooler than when it isn’t. The surface of our planet absorbs this heat from the Sun and emits it the same way that pavement continues to give off heat in the summer after the Sun goes down. Ouratmosphere does the same thing-it absorbs the heat that the ground emits and sends some of it back to the Earth.The Earth’s relationship with the Sun also creates seasons. The Earth’s axis tips a little-about 23.5 degrees. One hemisphere points toward the Sun as the other points away. Thehemisphere that points toward the Sun is warmer and gets more light--it’s summer there, and in the other hemisphere it’s winter. This effect is less dramatic near the equator than at the poles, since the equator receives about the same amount of sunlight all year. The poles, on the other hand, receive no sunlight at all during their winter months, which is part of the reason why they’re frozen.Most people are so used to the differences between night and day (or summer and winter) that they take them for granted.But these changes in light and temperature have an enormous impact on other systems on our planet. One is the circulation of air through our atmosphere. For example:The Sun shines brightly over the equator. The air gets very warm because the equator faces the Sun directly and because the ozone layer is thinner there.As the air warms, it begins to rise, creating a low pressure system. The higher it rises, the more the air cools. Water condenses as the air cools, creating clouds and rainfall. The air dries out as the rain falls. The result is warm, dry air, relatively high in our atmosphere.Because of the lower air pressure, air rushes toward the equator from the north and south. As it warms, it rises, pushing the dry air away to the north and the south.The dry air sinks as it cools, creating high-pressure areas and deserts to the north and south of the equator.This is just one piece of how the Sun circulates air around the world--ocean currents, weather patterns and other factors also play a part. But in general, air moves from high-pressure to low-pressure areas, much the way that high-pressure air rushes from the mouth of an inflated balloon when you let go. Heat also generally moves from the warmer equator to the cooler poles.Imagine a warm drink sitting on your desk--the air around the drink gets warmer as the drink gets colder. This happens on Earth on an enormous scale.The Coriolis Effect, a product of the Earth’s rotation, affects this system as well. It causes large weather systems, like hurricanes, to rotate. It helps create westward-running trade winds near the equator and eastward-running jet streams in the northem and southem hemispheres. These wind patterns move moisture and air from one place to another, creating weather patterns. (The Coriolis Effect works on a large scale--it doesn’t really affect the water draining from the sink like some people suppose. )The Sun gets much of the credit for creating both wind and rain. When the Sun warms air in a specific location, that air rises, creating an area of low pressure. More air rushes in from surrounding areas to fill the void, creating wind. Without the Sun, there wouldn’t be wind. There also might not be breathable air at all.Water and FireThe Sun has a huge effect’on our water. It warms the oceans around the tropics, and its absence cools the water around the poles. Because of this, ocean currents move large amounts of warm and cold water, drastically affecting the weather andclimate around the world. The Sun also drives the water cycle, which moves about 18,757 cubic miles (495,000 cubic kilometers) of water vapor through the atmosphere every year.If you’ve ever gotten out of a swimming pool on a hot day and realized a few minutes later that you were dry again, you have firsthand experience with evaporation. If you’ve seen water form on the side of a cold drink, you’ve seen condensation inaction. These are primary components of the water cycle, also called the hydrologic cycle,。

大学英语四级阅读理解模拟试题及答案

大学英语四级阅读理解模拟试题及答案大学英语四级阅读理解模拟试题及答案「篇一」1. C 细节题。

因为Leadville可以为Tabor带来巨富。

这一点不是Leadville得名的原因，因为在文章第二段中，讲到这一点时，提及三个原因：A.因为Tabor成为当地的居民代表人物，B.因为在Leadville有丰富的铅的储藏量。

D.因为Leadville是因为Tabor重要而起的名。

2. D 词汇题。

第二段中grubstake的词义与D所述内容是相同的，即“供给探矿者资金，衣物，食品以及其他物品”。

3. A 细节题。

Tabor第一次真正发财是他为两名矿工提供资助，为此他获得他们矿资源三分之一的股份。

见文章第三段4-9行内容：两名开矿者从Tabor那儿借走价值17美元的物品，作为回报，Tabor获得他们矿资源三分之一股份。

于是两位开矿者在一座山旁的不毛之地开始挖掘，九天之后，发现了银的富矿，于是Tabor又将两人的.股份全买下，这样，银矿属于Tabor一个人所有，这个矿就是后来著名的“匹兹堡”矿。

Tabor用17美元的投资换来了130万美元的收获。

4. B 推断题。

由原文可知泰勃的财产来源是有一定偶然性的，但是毕竟也是基于他开创“grubstake”模式，因为A、D都不对，C更是没有根据，因为他还没有娶第二位夫人这一切就发生了。

分析泰勃的做法，会得出B选项所示的结论。

5. B 推断题。

如果本文是一篇文章的第一部分，那么在文章的第二部分将介绍谁呢?可以从文章第一句分析出来，在Leadville的黄金年代，其多彩的特点当中，Tabor及其第二任妻子Elizabeth McCourt是值得大书特书的，接着，文章都在讲述有关H.A.W.Tabor发家致富的历史，如先买下匹兹堡矿，后又买下Matchless矿，最后成为市长，代理州长，等等，所以涉及到的全是男主人公，因此下边再讲的话，应成为女主人公即Elizabeth McCourt的天地了，她是Tabor的第二任妻子。
