That is, generally, younger people tend to outnumber older people on the front end of a technological shift. It is not always the case, though. When you look at attitudes toward driverless cars, there doesn’t seem to be a clear generational divide. The public overall is split on whether they’d like to use a driverless car. In a study last year, of all people surveyed, 48 percent said they wanted to ride in one, while 50 percent did not. The fact that attitudes toward self-driving cars appear to be so steady across generations suggests how transformative the shift to driverless cars could be. Not everyone wants a driverless car now—and no one can get one yet—but among those who are open to them, every age group is similarly engaged. Actually, this isn’t surprising. Whereas older generations are sometimes reluctant to adopt new technologies, driverless cars promise real value to these age groups in particular. Older adults, especially those with limited mobility or difficulty driving on their own, are one of the classic usecases for driverless cars. This is especially interesting when you consider that younger people are generally more interested in travel-related technologies than older ones. When it comes to driverless cars, differences in attitude are more pronounced based on factors not related to age. College graduates, for example, are particularly interested in driverless cars compared with those who have less education: 59 percent of college graduates said they would like to use a driverless car compared with 38 percent of those with a high-school diploma or less. Where a person lives matters, too. More people who lived in cities and suburbs said they wanted to try driverless cars than those who lived in rural areas. While there’s reason to believe that interest in self-driving cars is going up across the board, a person’s age will have little to do with how self-driving cars can become mainstream. Once driverless cars are actually available for sale, the early adopters will be the people who can afford to buy them.1．What happens when a new technology emerges?A．It further widens the gap between the old and the young.B．It often leads to innovations in other related fields.C．It contributes greatly to the advance of society as a whole.D．It usually draws different reactions from different age groups.正确答案：D解析：推理判断题。

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

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 .

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。

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 ARacket, din clamor, noise, whatever you want to call it, unwanted sound is America's most widespread nuisance. But noise is more than just a nuisance. It constitutes a real and present danger to people's health. Day and night, at home, at work, and at play, noise can produce serious physical and psychological stress. No one is immune to this stress. Though we seem to adjust to noise by ignoring it, the ear, in fact, never closes and the body still responds—sometimes with extreme tension, as to a strange sound in the night.The annoyance we feel when faced with noise is the most common outward symptom of the stress building up inside us. Indeed, because irritability is so apparent, legislators have made public annoyance the basis of many noise abatement programs. The more subtle and more serious health hazards associated with stress caused by noise traditionally have been given much less attention. Nevertheless, when we are annoyed or made irritable by noise, we should consider these symptoms fair warning that other thing may be happening to us, some of which may be damaging to our health.Of many health hazards to noise, hearing loss is the most clearly observable and measurable by health professionals. The other hazards are harder to pin down. For many of us, there may be a risk that exposure to the stress of noise increases susceptibility to disease and infection. The more susceptible among us may experience noise as a complicating factor in heart problems and other diseases. Noise that causes annoyance and irritability in health persons may have serious consequences for these already ill in mind or body.Noise affects us throughout our lives. For example, there are indications of effects on the unborn child when mothers are exposed to industrial and environmental noise. During infancy and childhood, youngsters exposed to high noise levels may have trouble falling asleep and obtaining necessary amounts of rest.Why, then, is there not greater alarm about these dangers? Perhaps it is because the link between noise and many disabilities or diseases has not yet been conclusively demonstrated. Perhaps it is because we tend to dismiss annoyance as a price to pay for living in the modern world. It may also be because we still think of hearing loss as only an occupational hazard.1. In Paragraph 1, the phrase "immune to" are used to mean ___.A.unaffected byB.hurt byC.unlikely to be seen byD.unknown by2.3. The author's attitude toward noise would best be described as ___.A.unrealisticB.traditionalC.concernedD.hystericalWhich of the following best states the main idea of the passage?A.Noise is a major problem; most people recognize its importance.B.Although noise can be annoying, it is not a major problem.C.Noise is a major problem and has not yet been recognized as such.D.Noise is a major problem about which nothing can be done.4.5. The author condemns noise essentially because it ___.A.is against the lawB.can make some people irritableC.is a nuisanceD.in a ganger to people's healthThe author would probably consider research about the effects noise has on people to be ___.A.unimportantB.impossible.C.a waste of moneyD.essentialTEXT BWhat we know of prenatal development makes all this attempt made by a mother to mold the character ofher unborn child by studying poetry, art, or mathematics during pregnancy seem utterly impossible. How could such extremely complex influences pass from the mother to the child? There is no connection between their nervous systems. Even the blood vessels of mother and child do not join directly. An emotional shock to the mother will affect her child, because it changes the activity of her glands and so the chemistry her blood. Any chemical change in the mother's blood will affect the child for better or worse. But we can not see how a looking for mathematics or poetic genius can be dissolved in blood and produce a similar liking or genius in the child.In our discussion of instincts we saw that there was reason to believe that whatever we inherit must be of some very simple sort rather than any complicated or very definite kind of behavior. It is certain that no one inherits a knowledge of mathematics. It may be, however, that children inherit more or less of a rather general ability that we may call intelligence. If very intelligent children become deeply interested in mathematics, they will probably make a success of that study.As for musical ability, it may be that what is inherited is an especially sensitive ear, a peculiar structure of the hands or the vocal organs connections between nerves and muscles that make it comparatively easy to learn the movements a musician must execute, and particularly vigorous emotions. If these factors are all organized around music, the child may become a musician. The same factors, in other circumstance might be organized about some other center of interest. The rich emotional equipment might find expression in poetry. The capable fingers might develop skill in surgery. It is not the knowledge of music that is inherited, then nor even the love of it, but a certain bodily structure that makes it comparatively easy to acquire musical knowledge and skill. Whether that ability shall be directed toward music or some other undertaking may be decided entirely by forces in the environment in which a child grows up.6. Which of the following statements is not true?A. Some mothers try to influence their unborn children by studying art and other subjects during theirpregnancy.B. It is utterly impossible for us to learn anything about prenatal development.C. The blood vessels of mother and child do not join directly.D. There are no connection between mother's nervous systems and her unborn child's.A mother will affect her unborn baby on the condition that ____.A. she is emotionally shocked7.B.she has a good knowledge of inheritanceC. she takes part in all kind of activitiesD. she sticks to studying8.9. According to the passage, a child may inherit____.A. everything from his motherB. a knowledge of mathematicsC. a rather general ability that we call intelligenceD. her mother's musical abilityIf a child inherits something from his mother, such as an especially sensitive ear, a peculiar structure of the hands or of the vocal organs, he will ____.A. surely become musicianB. mostly become a poetC. possibly become a teacherD. become a musician on the condition that all these factors are organized around music10. Which of the following is the best title for the passage?A. Role of Inheritance.B. An Unborn Child.C. Function of instincts.D. Inherited Talents.TEXT CThere 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 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 individual's 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. 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.11. This selection can best be titled____________.A. Measuring Your IntelligenceB. Intelligence and EnvironmentC. The Case of Peter and MarkD. How the Brain Influences Intelligence12.13. The best statement of the main idea of this passage is that _______.A. human brains differ considerablyB. the brain a person is born with is important in determining his intelligenceC. environment is crucial in determining a person's intelligenceD. persons having identical brains will have roughly the same intelligence According to the passage, the average I. Q. is_______.A. 85 .B. 100C. 110D. 12514. The case history of the twins appears to support the conclusion that_______.A. individuals with identical brains seldom test at the same levelB. an individual's intelligence is determined only by his environmentC. lack of opportunity blocks the growth of intelligenceD. changes of environment produce changes in the structure of the brain15. This passage suggests that an individual's I. Q. _______.A. can be predicted at birthB. stays the same throughout his lifeC. can be increased by educationD. is determined by his childhoodTEXT DPersonality is，to large extent, inherent --A-type parents usually bring about A-type offspring. But the environment must also have a profound effect, since if competition is improtant to the parents, it is likely to become a major factor lives of their children.One place where children soak up A characteristics is school, which is, by its very nature, a highly competitive institution. Too many schools adopt the "win at all costs" moral standard and measure their success by sporting achievements. The current passion for making children compete against their classmates or against the clock produces a two-layer system, in which competitive A types seem in some way better than their B-type fellows. Being too keen to win can have dangerous consequences:remember that Pheidippides ,the first marathon runner, dropped dead seconds after saying:"Rejoice, we conquer!".By far the worst form of competition in school is the disproportionate emphasis on examinations . It is a rare school that allows pupils to concentrate on those things they do well.The merits of competition by examination are somewhat questionable, but competition in the certain knowledge of failure is positively harmful.Obviously, it is neither practical nor desirable that all A youngsters change into 'B's. The would needs types, and schools have an important duty to try to fit a child's personality to his possible future employment. It is top management.16. According to the author, what factors contribute to the building of personality?A. inheritanceb. inheritance, competition and environmentc. competitiond. environment17. Which of the following statements is not true according to the author of the passage?A.Schools usually adopt severe competitive policies.B. Students are often divided by competition results.C. School is place where children cultivate their characteristics.D. The stronger desire for winning, the better.18. The phrase "soak up" is closest in meaning to ____.A. pull upb. take upc. take ind. pull in19. What attitude does the author hold toward examinations in schools?A. positiveb. negativec. doubtfuld. neutral20. what suggestion does the author make concerning the management of schools?A. All students be made into competitive A types.B. A child's personality be considered in regard to his possible future job.C. All students be changed into B characteristics.D.

英语四级CET4阅读练习题及答案
英语四级CET4阅读练习题及答案英语四级CET4精选阅读练习题及答案在当今这个学习英语风潮盛行的社会，英语似乎已经成为了我们生活中不可或缺的一部分，下面是小编为大家搜索整理的英语四级辅导练习，希望能给大家带来帮助!Henry III didn't know much about biology. He went through six wives back in the 1500s, looking for one whocould bear him a son. Scientists now know that it's the father's sperm, not the mother's egg, which determines whether a baby is a boy or a girl. And last week researchers at the Genetics and IVF Institute, a private fertility(生育能力)center in Virginia, announced a new technique that will allow parents to choose the sex of their baby-to-be, before it has even been conceived. The scientist used a tiny laser detector to measure the DNA in millions of sperm cells as they pass single file through a narrow tube, like cattle being herded through a corral(牲口栏). In a study published last week, "girl sperm," which has more DNA—the genetic material—in each cell, was collected, while "boy sperm" was discarded. And when purified girl sperm was used to impregnate(使受孕)a group of mothers, 15 of 17 resulting babies turned out to be girls.The researchers say that "sex selection" can also double a mother's chance of having a son and can be usedto avoid genetic diseases that affect only one gender, such as hemophilia(血友病). But some experts, like New York University fertility specialist Dr. Jamie Grifo, worry that sex selection could lead to a kind ofin uteri(子宫)discrimination, especially in cultures where sons are considered superior to daughters. "It's valuing one gender' over another," Grifo says. "I don't think that's something we should be doing." So far, patients at the institute have been asking for bothboys and girls, in order to "balance" their families. And some ethics experts say that's fine, as long as parents are just looking for a little gender variety. "If you have three boys, and you want a girl," says University of Texas reproductive-law professor John Robertson, "that's not gender bias at all."练习题：Choose correct answers to the question:1.The DNA in the sperm cells can be measured ______.A.in the same way how the cattle are herdedB.when they pass through a tube one behind the otherC.after they pass through a laser tubeD.when they are scanned by a laser detector all at a time2.The gender of the baby is decided by ______.A.the father's DNAB.the mother's DNAC.the father's spermD.the mother's egg3.According to this passage, the practice of "sex selection" ______.A.can help to prevent all genetic problemsB.is totally unacceptable to ethics expertsC.was already realized five hundred years agoD.will benefit families with certain inheritable diseases4.Girl sperm was preferred to boy sperm in the research most probably because____A.girl sperm contains more genetic materialB.more mother want to have girl babiesC.girl sperm is healthier and more activeD.girl sperm is more easily purified5.It can be concluded from the passage that author’stoward”sex selection”is____A.negativeB.positiveC.neutralD.favorable参考答案1.[B] 推理判断题。

英语四级阅读理解试题含答案
英语四级阅读理解试题含答案英语四级阅读理解试题：【原文】Three Kinds of FatigueFatigue is one of the most common complaints brought to doctors, friends, and relatives. Youd think in this era of labor-saving devices and convenient transportation that few people would have reason to be so tired. But probably more people complain of fatigue today than in the days when hay was baled by hand and laundry scrubbed on a washboard.The causes of modern-day fatigue are diverse and only rarely related to excessive physical exertion. The relatively few people who do heavy labor all day long almost never complain about being tired, perhaps because they expect to be. Today, physicians report, tiredness is more likely a consequence of under-exertion than of wearing yourself down with over-activity. In fact, increased physical activity is often prescribed as a cure for lowering energy.Physical. This is the well-known result of overworking your muscles to the point where metabolic (新成代谢的) waste products—carbon dioxide and lactic acid (乳酸)—accumulate in our blood and reduce your strength. Your muscles cant continue to work efficiently in a bath of these chemicals. Physical fatigue is usually a pleasant tiredness, such as that which you might experience after playing a hard set of tennis, chopping wood, orclimbing a mountain. The cure is simple and fast: You rest, giving your body a chance to get rid of accumulated wastes and restore muscle fuel.Pathological (病理的). Here fatigue is a warning sign or consequence of some underlying physical disorder, perhaps the common cold or flu or something more serious like diabetes or cancer. Usually other symptoms besides fatigue are present that suggest the true cause.Even after an illness has passed, youre likely to feel dragged out for a week or more. Take your fatigue as a signal to go slow while your body has a chance to recover fully even if all you had was a cold. Pushing yourself to resume full activity too soon could lead to a relapse (旧病复发) and almost certainly will prolong our period of fatigue.Even though illness is not frequent cause of prolonged fatigue, its very important that it not be overlooked. Therefore, anyone who feels drained of energy for weeks on end should have a thorough physical check-up. But even if nothing shows up as a result of the various medical tests, that doesnt mean theres nothing wrong with you.Psychological. Emotional problems and conflicts, especially depression and anxiety, are by far the most common causes of prolonged fatigue. Fatigue may represent a defence mechanism that prevents you from having to face the true cause of your depression, such as the fact that you hate your job. It is also your bodys safety mechanism for expressing repressed emotional conflicts, such as feeling trapped in an ungrateful role or an unhappy marriage. When such feelings are not expressed openly, they often come out as physical symptoms, with fatigue as one of the most common manifestations. "Many people who are extremely fatigued dont even know theyre depressed," Dr. Bulette says. "Theyre so busy distractingthemselves or just worrying about being tired that they dont recognize their depression. "There is a great deal you can do on your own to deal with both severe prolonged fatigue and those periodic washed-out feelings. Vitamins and tranquilizers (镇静剂 ) are almost never the right answer, sleeping pills and alcohol are counterproductive, and caffeine is at best a temporary solution that can backfire with abuse and cause life-disrupting symptoms of anxiety. Instead, you might try: DietIf you eat a small breakfast or none at all, youre likely to experience mid-morning fatigue, the result of a drop in blood sugar, which your body and brain depend on for energy. For peak energy in the morning, be sure to eat a proper breakfast, low in sugar and fairly high in protein, which will provide a steady supply of blood sugar throughout the morning. Coffee and a doughnut are almost worse than nothing, providing a brief boost and then letting you down with a thud. ExerciseContrary to what you may think, exercise enhances, rather than saps, energy. Regular conditioning exercises, such as jogging, cycling, or swimming, help you to resist fatigue by increasing your bodys ability to handle more of a work load. You get tired less quickly because your capability is greater.Exercise also has a well-recognized tranquilizing effect, which helps you work in a more relaxed fashion and be less dragged down by the tensions of your day. At the end of a day exercise can relieve accumulated tensions, give you more energy in the evening, and help you sleep more restfully.SleepIf you know youre tired because you havent been getting enough sleep, the solution is simple: Get to bed earlier. Theres no right amount of sleep for everyone, and generally sleep requirements decline with age. Find the amount that suits you best, and aim for it. Insomnia(失眠) and other sleep disorders should not be treated with sleeping pills, alcohol, or tranquilizers, which can actually make the problem worse.Know yourselfTry to schedule your most difficult jobs for the time of day when youre at your peak. Some are "morning people" who tire by mid-afternoon; others do their best work in the evening. Dont overextend yourself, trying to climb the ladder of success at a record pace or to meet everyones demands or expectations. Decide what you want to do and what you can handle comfortably, and learn to say no to additional requests. Recognize your energy cycles and plan accordingly. Many women have a low point premenstrually, during which time extra sleep may be needed and demanding activities are particularly exhausting. , Take breaksNo matter how interesting or demanding you work, youll be able to do it with more vigor if now and again you stop, stretch, and change the scenery. Instead of coffee and a sweet roll on your break, try meditation, yoga, callisthenics(健美操) , or a brisk walk. Even running up and down the staircase can provide refreshment from a sedentary(久坐的) job. If your job is physically demanding, relax in a quiet place for a while. The do-something-different rule also applies to vacation; "getting away from it all" for a week or two or longer can be highly revitalizing, helping you to put things in perspective and enabling you to take your job more in stride upon your return.英语四级阅读理解试题：【题目】1.

大学英语四级阅读习题及答案
大学英语四级阅读习题及答案大学英语四级阅读习题(一)1、A2、D3、C4、C5、B大学英语四级阅读习题答案Acculturation, which begins at birth, is the process of teaching new generations of children the customs and values of the parents culture. How people treat newborns, for example, can be indicative of cultural values. In the United States it is not uncommon for parents to put a newborn in a separate room that belongs only to the child. This helps to preserve parents privacy and allows the child to get used to having his or her own room, which is seen as a first step toward personal independence. Americans traditionally have held independence and a closely related value, individualism, in high esteem. Parents try to instill these prevailing values in their children. American English expresses these value preferences: children should "cut the (umbilical) cord" and are encouraged not to be "tied to their mothers apron strings." In the process of their socialization children learn to "look out for number one" and to "stand on their own two feet".Many children are taught at a very early age to make decisions and be responsible for their actions. Often children work for money outside the home as a first step to establishing autonomy. Nine-or ten-year-old children may deliver newspapers in their neighborhoods and save or spend their earnings. Teenagers (13 to 18 years) may baby-sit neighbors homes in order to earn a few dollar a week. Receiving a weekly allowance at an early age teaches children to budget their money, preparing them for future financial independence. Many parents believe that managing money helps children learn responsibility as well as appreciate the value of money.21.

It can be inferred from this passage that _____.A) Americans are money loversB) Americans admire independenceC) Americans are good at decision-makingD) Americans are all responsible大学英语四级阅读习题(二)Long after the 1998 World Cup was won, disappointed fans were still cursing the disputed refereeing (裁判) decisions that denied victory to their team. A researcher was appointed to study the performance of some top referees.The researcher organized an experimental tournament (锦标赛) involving four youth teams. Each match lasted an hour, divided into three periods of 20 minutes during which different referees were in charge.Observers noted down the referees errors, of which there were 61 over the tournament. Converted to a standard match of 90 minutes, each referee made almost 23 mistakes, a remarkably high number.The researcher then studied the videotapes to analyse the matches in detail. Surprisingly, he found that errors were more likely when the referees were close to the incident. When the officials got it right, they were, on average, 17 meters away from the action. The average distance in the case of errors was 12 meters. The research shows the optimum (最佳的) distance is about 20 meters.There also seemed to be an optimum speed. Correct decisions came when the referees were moving at a speed of about 2 meters per second. The average speed for errors was 4 meters per second.If FIFA, footballs international ruling body, wants to improve the standard of refereeing at the next World Cup, it should encourage referees to keep their eyes on the action from a distance, rather than rushing to keep up with the ball, the researcher argues.He also says that FIFAs insistence that referees should retire at age 45 may be misguided. If keeping up with the action is not so important, their physical condition is less critical.21. The experiment conducted by the researcher was meant to ________.A) review the decisions of referees at the 1998 World CupB) analyse the causes of errors made by football refereesC) set a standard for football refereeingD) reexamine the rules for football refereeing22. The number of refereeing errors in the experimental matches was ________.A) slightly above averageB) higher than in the 1998 World CupC) quite unexpectedD) as high as in a standard match23. The findings of the experiment show that ________.A) errors are more likely when a referee keeps close to the ballB) the farther the referee is from the incident, the fewer the errorsC) the more slowly the referee runs, the more likely will errors occurD) errors are less likely when a referee stays in one spot24. The word “officials” (Line 2, Para. 4) most probably refers to ________.A) the researchers involved in the experimentB) the inspectors of the football tournamentC) the referees of the football tournamentD) the observers at the site of the experiment25. What is one of the possible conclusions of the experiment?A) The ideal retirement age for an experienced football referee is45.B) Age should not be the chief consideration in choosing a football referee.C) A football referee should be as young and energetic as possible.D) An experienced football referee can do well even when in poor physical condition.。

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

The social and educational significance of the readers' books cannot be overestimated in an academic library.Section BPassage oneQuestion 57 to 61 are based on the following passage.If you’re a male and you’re reading this , congratulations : you’re a survivor. According to statistics, you’re more than twice as likely to die of skin cancer than a woman ,and nine times more likely to die of AIDS . Assuming you make it to the end of your natural term, about 78years for men in Australia , you’ll die on average five years before a woman.There’re many reasons for this ---typically , men take more risks than women and are more likely to drink and smoke—but perhaps more importantly , men don’t go to the doctor.“men aren’t seeing doctors as often as they should ,” says Dr.Gullotta . “this is particularly so for the over-40s, when diseases tend to strike .”Gullotta say a healthy man should visit the doctor every year or two . For those over 45,it should be at least once a year .Two months ago Gullotta saw a 50-year-old man who had delayed doing anything about his smo ker’s cough for a year .“when I finally saw him it had already spread and he has since died from lung cancer ,” he says. “Earlier detection and treatment may not have cured him but it would have prolonged his life .”According to a recent survey ,95% of women aged between 15 and early 40s see a doctor once a year , compared to 70% of men in the same age group.“A lot of men think they’re invincible(不可战胜的),” Gullatta says . “they only come in when a friend drops dead on the golf course and the y think ,’Geez,if it could happen to him ,……’ ”Then there’s the ostrich approach .”Some men are scared of what might be there and would rather not know ,” says Dr.Ross Cartmill.“most men get their cars serviced more regularly than they service th eir bodies ,” Garmill says .He believes most diseases that commonly affect men could be addressed by preventive check-ups.Regular check-us for men would inevitably lace strain on the public purse , Cartmill says . “but prevention is cheaper in the long ru n than having to treat the disease . Besides , the ultimate cost is far greater :it’s called premature death .”注意：此部分试题请在答题卡2上作答57．Why does the author congratulate his male readers at the beginning of the passage ?A)They are more likely to survive serious diseases todayB）Their average life span has been considerably extendedC)They have lived long enough to read this articleD)They are sure to enjoy a longer and happier life58.What does the author state is the most important reason men die five years earlier on average than women ?A)men drink and smoke much more than womenB)men don’t seek medical care as often as womenC)men aren’t as cautious as women in face of dangerD)men are more likely to suffer from fatal disease59.Which of the following best completes the sentence “Geez ,if it could happen to him, ...”(line 2, para.8)A)it could happen to me ,tooB）I should avoid playing golfC)I should consider myself luckyD)it would be a big misfortune60. what does Dr.Ross Cartmill mean by “the ostrich approach “(Line 1 ,Para 9)A)A cause attitude towards one’s health conditionsB)A new therapy for certain psychological problemsC)Refusal to get medical treatment for fear of the pain involvedD)Unwillingness to find out about one’s disease because of fear61.What does Cartmill say about regular check-ups for men ?A)They may increase public expenseB)They will save money in the long runC)They may cause psychological strain s on menD)They will enable men to live as long as womenPassage twoQuestion 62 to 66 are based on the following passage.High-quality customer service is preached by many, but actually keeping customers happy is easier said than done.Shoppers seldom complain to the manager or owner of a retail store ,but instead will alert their friends, relatives, co-workers, strangers and anyone who will listen.Store managers are often the last to hear complaints,and often find out only when their regular customers decide to frequent their competitors, according to study jointly conducted by Verde Group and Wharton School.“storytelling hurts retailers and entertains consumers” said Paula Courtney, Preside nt of the Verde Group. “The store losers the customer, but the shopper must also find a replacement”On average, every unhappy customer will complain to at least four others, and will no longer visit the specific store. For every dissatisfied customer, a store will lose up to three more due to negative reviews. The resulting “snowball effect” can be disastrous to retailers.According to the research, shopper who purchased clothing encountered the most problem Ranked second and third were grocery and electronics customers.The most common complaints include filled parking lots, cluttered shelves over loaded racks, out-of-stock items, long check-out lines, and rude salespeople.During peak shopping hours, some retailers solved the parking problems by getting moonlighting (业余兼职的) local police to work as parking attendants. Some hired flag wavers to direct customers to empty parking spaces. This guidance eliminated the need for customers to circle the parking lot endlessly , and avoided confrontation between those eyeing the same parking space.Retailers can relieve the headaches by redesigning store layouts, pre-stocking sales items, hiring speedy and experienced cashiers , and having sales representatives on hand to answer question .Most importantly , salespeople should be diplomatic and polite with angry customers .“Retailers who’er responsive and friendly are more likely to smooth over issues than those who aren’t so friendly , “ said professor Stephen Hoch .” Maybe something as simple as a greeter at the store entrance would help .“Customers can also improve future shopping experiences by filing complaints to the retailer , instead of complaining to the rest of the world . Retailers are hard-pressed to improve when they hace no idea what is wrong.注意：此部分试题请在答题卡2上作答。

大学英语四级CET4阅读理解考试题及答案
大学英语四级CET4阅读理解考试题及答案大学英语四级CET4阅读理解考试题及答案英语作为文科科目当中的一个重要组成部分，需要记忆理解的东西比理科要多的多，所以复习的战线需要拉得更长，下面是小编为大家搜索整理的英语四级辅导练习，希望能给大家带来帮助!Japan is getting tough about recycling—and not inthe paper and plastic kind of way. Recently, thecountry requires that all electronic goods—TVs,VCRs, stereos, and more—be recycled. But recyclingwill not beleft to consumers, instead, the devices willbe sent to the original manufacturer for properdisposal.The new law poses a few challenges to manufacturers who are now rushing to set up collectionnetworks and perfecting techniques to disassemble and recycle older products.With an eyetoward the future, they are also integrating easily recycled materials into new products.Plastics, a major component of most electronicproducts,pose a particular obstacle becausetheir quality becomes worse and worse with age,losing strengthand flexibility even ifreprocessed.NEC Corp. overcomes this problem by creating a plastics sandwich, in which thefilling is 100 percent recycled plastic and the outer layers a mixture of 14 percent recycledmaterial.The resulting plastic has sufficient strength and toughness for use as a case fordesktop PCs. The company, in cooperation with plastic maker Sumitomo Dow, has alsodeveloped a new plastic, which engineers claim retains its mechanical properties throughrepeated recycling. NEC uses the plastic, which is also flame-retardant (阻燃的) in batterycases for notebook PCs.Meanwhile, Matsushita Electric, maker of the Panasonic brand, is avoiding plastic in favor ofmagnesium (镁). Magnesium,says the company, is ideal for re cycling because it retains itsoriginal strength throughrepeated reprocessing. Matsushita has developed moldingtechniques to form magnesium into the case for a 21-inch TV. Unfortunately, the magnesiumcase and energy-saving features make the TV about twice as expensive as an ordinarymodel.The company hopes, however, that increased use of magnesium will eventually bringprices down.练习题：Choose correct answers to the question:1. According to the present regulations of Japan, the recycling of paper and plasticwill be the responsibility of______.A.. the governmentB. the manufacturersC. the consumersD. the sellers2. Which of the following is NOT the character of plastics?A. Most electronic products contain plastics.B. It retains its original strength through reprocessing.C. Recycled plastics can be integrated into new products.D. Plastics will lose flexibility after a certain period of time.3.According to the passage, the term “plastic sandwich” refers to_____.A. a kind of sandwich-shaped toy made of plasticsB. a kind of plastics with different integration in each layerC. a kind of plastics with maximum strength and flexibilityD. a kind of plastics made of 100% recycled materials4.In the passage, it is implied but NOT stated that_____.A. disposing the plastics is one of NEC Corp’s businessesB. magnesium is an ideal material for the case of TVC.21-inch TV with magnesium case isn’t very popular so farD. magnesium must be better than the plastics5.The author writes this passage in order to_____.A. informB. instructC. predictD. persuade参考答案1.[C] 推理判断题。

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 ARacket, din clamor, noise, whatever you want to call it, unwanted sound is America's most widespreadnuisance. But noise is more than just a nuisance. It constitutes a real and present danger to people's health. Dayand night, at home, at work, and at play, noise can produce serious physical and psychological stress. No one isimmune to this stress. Though we seem to adjust to noise by ignoring it, the ear, in fact, never closes and thebody still responds—sometimes with extreme tension, as to a strange sound in the night.The annoyance we feel when faced with noise is the most common outward symptom of the stress buildingup inside us. Indeed, because irritability is so apparent, legislators have made public annoyance the basis ofmany noise abatement programs. The more subtle and more serious health hazards associated with stresscaused by noise traditionally have been given much less attention. Nevertheless, when we are annoyed or madeirritable by noise, we should consider these symptoms fair warning that other thing may be happening to us,some of which may be damaging to our health.Of many health hazards to noise, hearing loss is the most clearly observable and measurable by healthprofessionals. The other hazards are harder to pin down. For many of us, there may be a risk that exposure to thestress of noise increases susceptibility to disease and infection. The more susceptible among us may experiencenoise as a complicating factor in heart problems and other diseases. Noise that causes annoyance and irritabilityin health persons may have serious consequences for these already ill in mind or body.Noise affects us throughout our lives. For example, there are indications of effects on the unborn child whenmothers are exposed to industrial and environmental noise. During infancy and childhood, youngsters exposedto high noise levels may have trouble falling asleep and obtaining necessary amounts of rest.Why, then, is there not greater alarm about these dangers? Perhaps it is because the link between noise andmany disabilities or diseases has not yet been conclusively demonstrated. Perhaps it is because we tend todismiss annoyance as a price to pay for living in the modern world. It may also be because we still think ofhearing loss as only an occupational hazard.1.In Paragraph 1, the phrase "immune to" are used to mean ___.A.unaffected byB.hurt byC.unlikely to be seen byD.unknown by2.The author's attitude toward noise would best be described as ___.A.unrealisticB.traditionalC.concernedD.hysterical3.Which of the following best states the main idea of the passage?A.Noise is a major problem; most people recognize its importance.B.Although noise can be annoying, it is not a major problem.C.Noise is a major problem and has not yet been recognized as such.D.Noise is a major problem about which nothing can be done.4.The author condemns noise essentially because it ___.A.is against the lawB.can make some people irritableC.is a nuisanceD.in a ganger to people's health5.The author would probably consider research about the effects noise has on people to be ___.A.unimportantB.impossible.C.a waste of moneyD.essentialTEXT BWhat we know of prenatal development makes all this attempt made by a mother to mold the character of her unborn child by studying poetry, art, or mathematics during pregnancy seem utterly impossible. How could such extremely complex influences pass from the mother to the child? There is no connection between their nervous systems. Even the blood vessels of mother and child do not join directly. An emotional shock to the mother will affect her child, because it changes the activity of her glands and so the chemistry her blood. Any chemical change in the mother's blood will affect the child for better or worse. But we can not see how a looking for mathematics or poetic genius can be dissolved in blood and produce a similar liking or genius in the child.In our discussion of instincts we saw that there was reason to believe that whatever we inherit must be of some very simple sort rather than any complicated or very definite kind of behavior. It is certain that no one inherits a knowledge of mathematics. It may be, however, that children inherit more or less of a rather general ability that we may call intelligence. If very intelligent children become deeply interested in mathematics, theywill probably make a success of that study.As for musical ability, it may be that what is inherited is an especially sensitive ear, a peculiar structure of the hands or the vocal organs connections between nerves and muscles that make it comparatively easy to learn the movements a musician must execute, and particularly vigorous emotions. If these factors are all organized around music, the child may become a musician. The same factors, in other circumstance might be organized about some other center of interest. The rich emotional equipment might find expression in poetry. The capable fingers might develop skill in surgery. It is not the knowledge of music that is inherited, then nor even the love of it, but a certain bodily structure that makes it comparatively easy to acquire musical knowledge and skill. Whether that ability shall be directed toward music or some other undertaking may be decided entirely by forces in the environment in which a child grows up.6.Which of the following statements is not true?A. Some mothers try to influence their unborn children by studying art and other subjects during theirpregnancy.B. It is utterly impossible for us to learn anything about prenatal development.C. The blood vessels of mother and child do not join directly.D. There are no connection between mother's nervous systems and her unborn child's.7. A mother will affect her unborn baby on the condition that ____.A. she is emotionally shockedB.she has a good knowledge of inheritanceC. she takes part in all kind of activitiesD. she sticks to studying8.According to the passage, a child may inherit____.A. everything from his motherB. a knowledge of mathematicsC. a rather general ability that we call intelligenceD. her mother's musical ability9.If a child inherits something from his mother, such as an especially sensitive ear, a peculiar structure of thehands or of the vocal organs, he will ____.A. surely become musicianB. mostly become a poetC. possibly become a teacherD. become a musician on the condition that all these factors are organized around music10.Which of the following is the best title for the passage?A. Role of Inheritance.B. An Unborn Child.C. Function of instincts.D. Inherited Talents.TEXT CThere 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 hasto begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So thesecond 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 individual's 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 theirgrowth processes were the same. When the twins were three months old, their parents died, and they wereplaced 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 tocollege. 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 weregiven tests to measure their intelligence. Mark's I. Q. was 125, twenty-five points higher than the average andfully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains,would have tested at roughly the same level.11.This selection can best be titled____________.A. Measuring Your IntelligenceB. Intelligence and EnvironmentC. The Case of Peter and MarkD. How the Brain Influences Intelligence12.The best statement of the main idea of this passage is that _______.A. human brains differ considerablyB. the brain a person is born with is important in determining his intelligenceC. environment is crucial in determining a person's intelligenceD. persons having identical brains will have roughly the same intelligence13.According to the passage, the average I. Q. is_______.A. 85 .B. 100C. 110D. 12514.The case history of the twins appears to support the conclusion that_______.A. individuals with identical brains seldom test at the same levelB. an individual's intelligence is determined only by his environmentC. lack of opportunity blocks the growth of intelligenceD. changes of environment produce changes in the structure of the brain15.This passage suggests that an individual's I. Q. _______.A. can be predicted at birthB. stays the same throughout his lifeC. can be increased by educationD. is determined by his childhoodTEXT DPersonality is，to large extent, inherent --A-type parents usually bring about A-type offspring. But the environment must also have a profound effect, since if competition is improtant to the parents, it is likely to become a major factor lives of their children.One place where children soak up A characteristics is school, which is, by its very nature, a highly competitive institution. Too many schools adopt the "win at all costs" moral standard and measure their success by sporting achievements. The current passion for making children compete against their classmates or against the clock produces a two-layer system, in which competitive A types seem in some way better than their B-type fellows. Being too keen to win can have dangerous consequences:remember that Pheidippides ,the first marathon runner, dropped dead seconds after saying:"Rejoice, we conquer!".By far the worst form of competition in school is the disproportionate emphasis on examinations . It is a rare school that allows pupils to concentrate on those things they do well.The merits of competition by examinationare somewhat questionable, but competition in the certain knowledge of failure is positively harmful.Obviously, it is neither practical nor desirable that all A youngsters change into 'B's. The would needs types, and schools have an important duty to try to fit a child's personality to his possible future employment. It is top management.16.According to the author, what factors contribute to the building of personality?A. inheritanceb. inheritance, competition and environmentc. competitiond. environment17.Which of the following statements is not true according to the author of the passage?A.Schools usually adopt severe competitive policies.B. Students are often divided by competition results.C. School is place where children cultivate their characteristics.D.

大学英语英语四级练习卷(及答案) (4)
大学英语四级试练习卷一、阅读理解阅读理解（一）Why the inductive and mathematical sciences, after their first rapid development at the culmination of Greek civilization, advanced so slowly for two thousand years—and why in the following two hundred years a knowledge of natural and mathematical science has accumulated, which so vastly exceeds all that was previously known that these sciences may be justly regarded as the products of our own times—are questions which have interested the modern philosopher not less than the objects with which these sciences are more immediately conversant. Was it the employment of a new method of research, or in the exercise of greater virtue in the use of the old methods, that this singular modern phenomenon had its origin? Was the long period one of arrested development, and is the modern era one of normal growth? Or should we ascribe the characteristics of both periods to so-called historical accidents—to the influence of conjunctions in circumstances of which no explanation is possible, save in the omnipotence and wisdom of a guiding Providence?The explanation which has become commonplace, that the ancients employed deduction chiefly in their scientific inquiries, while the moderns employ induction, proves to be too narrow, and fails upon close examination to point with sufficient distinctness the contrast that is evident between ancient and modern scientific doctrines and inquiries. For all knowledge is founded on observation, and proceeds from this by analysis, by synthesis and analysis,by induction and deduction, and if possible by verification, or by new appeals to observation under the guidance of deduction—by steps which are indeed correlative parts of one method; and the ancient sciences afford examples of every one of these methods, or parts of one method, which have been generalized from the examples of science.A failure to employ or to employ adequately any one of these partial methods, an imperfection in the arts and resources of observation and experiment, carelessness in observation, neglect of relevant facts, by appeal to experiment and observation—these are the faults which cause all failures to ascertain truth, whether among the ancients or the moderns; but this statement does not explain why the modern is possessed of a greater virtue, and by what means he attained his superiority. Much less does it explain the sudden growth of science in recent times.The attempt to discover the explanation of this phenomenon in the antithesis of “facts” and “theories” or “facts” and “ideas”—in the neglect among the ancients of the former, and their too exclusive attention to the latter —proves also to be too narrow, as well as open to the charge of vagueness. For in the first place, the antithesis is not complete. Facts and theories are not coordinate species. Theories, if true, are facts—a particular class of facts indeed, generally complex, and if a logical connection subsists between their constituents, have all the positive attributes of theories. Nevertheless, this distinction, however inadequate it may be to explain the source of true method in science, is well founded, and connotes an important character in true method. A fact is a proposition of simple. A theory, on theother hand, if true has all the characteristics of a fact, except that its verification is possible only by indirect, remote, and difficult means. To convert theories into facts is to add simple verification, and the theory thus acquires the full characteristics of a fact."1. The title that best expresses the ideas of this passage is"[A]. Philosophy of mathematics. [B]. The Recent Growth in Science.[C]. The Verification of Facts. [C]. Methods of Scientific Inquiry."2. According to the author, one possible reason for the growth of science during the days of the ancient Greeks and in modern times is"[A]. the similarity between the two periods.[B]. that it was an act of God.[C]. that both tried to develop the inductive method.[D]. due to the decline of the deductive method."3. The difference between “fact” and “theory”"[A]. is that the latter needs confirmation.[B]. rests on the simplicity of the former.[C]. is the difference between the modern scientists and the ancient Greeks.[D]. helps us to understand the deductive method."4. According to the author, mathematics is"[A]. an inductive science. [B]. in need of simple verification.[C]. a deductive science. [D]. based on fact and theory."5. The statement “Theories are facts” may be called."[A]. a metaphor. [B]. a paradox.[C]. an appraisal of the inductive and deductive methods.[D]. a pun.阅读理解（二）On the 36th day after they had voted, Americans finally learned Wednesday who would be their next president: Governor George W. Bush of Texas.Vice President Al Gore, his last realistic avenue for legal challenge closed by a U. S. Supreme Court decision late Tuesday, planned to end the contest formally in a televised evening speech of perhaps 10 minutes, advisers said. They said that Senator Joseph Lieberman, his vice presidential running mate, would first make brief comments. The men would speak from a ceremonial chamber of the Old Executive office Building, to the west of the White House.The dozens of political workers and lawyers who had helped lead Mr. Gore’s unprecedented fight to claw a come-from-behind electoral victory in the pivotal state of Florida were thanked Wednesday and asked to stand down. “The vice president has directed the recount committee to suspend activities,”William Daley, the Gore campaign chairman, said in a written statement. Mr. Gore authorized that statement after meeting with his wife, Tipper, and with top advisers including Mr. Daley.He was expected to telephone Mr. Bush during the day. The Bush campaign kept a low profile and moved gingerly, as if to leave space for Mr. Gore to contemplate his next steps.Yet, at the end of a trying and tumultuous process that had focused world attention on sleepless vote counters across Florida, and on courtrooms formMiami to Tallahassee to Atlanta to Washington the Texas governor was set to become the 43d U. S. president.The news of Mr. Gore’s plans followed the longest and most rancorous dispute over a U. S. presidential election in more than a century, one certain to leave scars in a badly divided country.It was a bitter ending for Mr. Gore, who had outpolled Mr. Bush nationwide by some 300000 votes, but, without Florida, fell short in the Electoral College by 271votes to 267—the narrowest Electoral College victory since the turbulent election of 1876.Mr. Gore was said to be distressed by what he and many Democratic activists felt was a partisan decision from the nation’s highest court.The 5-to –4 decision of the Supreme Court held, in essence, that while a vote recount in Florida could be conducted in legal and constitutional fashion, as Mr. Gore had sought, this could not be done by the Dec. 12 deadline for states to select their presidential electors.James Baker 3rd, the former secretary of state who represented Mr. Bush in the Florida dispute, issued a short statement after the U. S. high court ruling, saying that the governor was “very pleased and gratified.”Mr. Bush was planning a nationwide speech aimed at trying to begin to heal the country’s deep, aching and varied divisions. He then was expected to meet with congressional leaders, including Democrats. Dick Cheney, Mr. Bush’s ruing mate, was meeting with congressmen Wednesday in Washington.When Mr. Bush, who is 54, is sworn into office on Jan.20, he will be only the second son of a president to follow his father to the White House, after JohnAdams and John Quincy Adams in the early 19th century.Mr. Gore, in his speech, was expected to thank his supporters, defend his hive-week battle as an effort to ensure, as a matter of principle, that every vote be counted, and call for the nation to join behind the new president. He was described by an aide as “resolved and resigned.”While some constitutional experts had said they believed states could present electors as late as Dec. 18, the U. S. high court made clear that it saw no such leeway.The U.S. high court sent back “for revision” to the Florida court its order allowing recounts but made clear that for all practical purposes the election was over.In its unsigned main opinion, the court declared, “The recount process, in its features here described, is inconsistent with the minimum procedures necessary to protect the fundamental right of each voter.”That decision, by a court fractured along philosophical lines, left one liberal justice charging that the high court’s proceedings bore a political taint.Justice John Paul Stevens wrote in an angry dissent:” Although we may never know with complete certainty the identity of the winner of this year’s presidential election, the identity of the loser is perfectly clear. It is the nation’s confidence in the judge as an impartial guardian of the law.”But at the end of five seemingly endless weeks, during which the physical, legal and constitutional machines of the U. S. election were pressed and sorely tested in ways unseen in more than a century, the system finally produced aresult, and one most Americans appeared to be willing at lease provisionally to support.The Bush team welcomed the news with an outward show of restraint and aplomb. The governor’s hopes had risen and fallen so many times since Election night, and the legal warriors of each side suffered through so many dramatic reversals, that there was little energy left for celebration."1. The main idea of this passage is"[A]. Bush’s victory in presidential election bore a political taint.[B]. The process of the American presidential election.[C]. The Supreme Court plays a very important part in the presidential election.[D]. Gore is distressed."2. What does the sentence “as if to leave space for Mr. Gore to contemplate his next step” mean"[A]. Bush hopes Gore to join his administration.[B]. Bush hopes Gore to concede defeat and to support him.[C]. Bush hopes Gore to congraduate him.[D]. Bush hopes Gore go on fighting with him."3. Why couldn’t Mr. Gore win the presidential election after he outpolled Mr. Bush in the popular vote? Because"[A]. the American president is decided by the supreme court’s decision.[B]. people can’t directly elect their president.[C]. the American president is elected by a slate of presidential electors.[D]. the people of each state support Mr. Bush."4. What was the result of the 5—4 decision of the supreme court?"[A]. It was in fact for the vote recount.[B]. It had nothing to do with the presidential election.[C]. It decided the fate of the winner.[D]. It was in essence against the vote recount."5. What did the “turbulent election of 1876” imply?"[A]. The process of presidential election of 2000 was the same as that.[B]. There were great similarities between the two presidential elections (2000 and 1876).[C]. It was compared to presidential election of 2000.[D]. It was given an example.阅读理解（三）Asked to name their favorite city, many Amerians would select San Francisco began as a small Spanish outpost located on a magnificent bay.The town was little more than a village serving ranchers when the United States took possession of it in 1846 during the war with Mexico. San Francisco sprang into a city overnight because of the nearby discovery of gold in 1848.A great rush to California took place.Wagon trains plodded their dangerous way across 2000 miles of prairie and mountains,while hundreds of sailing vessels made the equally hazardous trip around the Horn.The vessels disgorged thousands of passengers -- then the crews deserted teir ship and hundreds of vessels were left to rot in thebay.Within two years,California had enough population to become a state and San Francisco was for many years the hub of that newly-arrived population.The city’s present popularity is due to an excellent climate, an easy style of living ,good food,and numerous tourist attractions. The city is famous for its cable cars which "clang and bang" up the steep hills,and for its excellent seafood stals along the wharf.

大学生英语四级考试阅读理解试题及答案解析1The world has become a world of cities. With the present rate of urban growth(3. 8% in the Third World) , the majority of the population of the world will be living in cities by the year 2000. This will transform the rural-urban equation which has marked the history of mankind up to now and will call for new example and a great deal of innovation to face this phenomenon.This being so, one must accept the fact that for some years to come, no policy will be capable of stopping or reversing the present migratory trend from the rural areas to the cities in the Third World. In Africa, the urban population will reach 330 million people by the end of the century as against 150 million in 1995.The number of people living in shanty-towns (贫富窟) will inevitably increase in spite of the efforts to improve housing conditions.Africa alone needs to build 12 million housing units between now and the year 2000 to meet its most basic needs. In an ILO study, M. S. V. Sethuraman estimates that in 70 Third "World cities the proportion of people living in shanty-towns varies from 15% to 70% and that about US $ 116 billion is required to give minimum comfort to these people by the turn of the century—less than US $ 10 billion per year.The world population is growing at a rate of about 90 million people per year, with the Third World accounting for 80 million of them. The pressure on cities can only go on increasing. The urban population of the developing countries will exceed 2 billion people by the year 2000 and since the main reason for the high demographic (人口统计的) growth is poverty, the additional population will be mostly made of people of very limited means.21. If the urban population of the developing countries exceeds 2 billion people by the year 2000, the main problem the additional people will face is______.A. housingB. foodC. povertyD. limited land22. According to the passage, "about US $116 billion is required to give minimum comfort to these people by the turn of the century—less than US $ 10 billion per year. " Do you think which year was the article written by saying "less than $ 10 billion per year" by theturn of the century?A. 1985.B. 1990.C. 1988.D. 2000.23. The mankind should face the phenomenon that the world has become a world of cities with______.A. a lot of difficultiesB. efforts to improve housing conditionC. pressure of the basic needsD. new models and a great deal of transformation of ideas and methods24. In Africa, people in cities will be______by the end of the century.A. almost twice as much as in 1985B. doubled than that in 1985C. over twice as much as in 1985D. 300 million25. In spite of the efforts to improve housing condition, the number of people living in shanty-towns will increase because______.A. houses in shanty-towns are cheapB. shanty-towns could provide people with minimum comfortC. no policy will be capable of stopping or changing the present immigrant tendency from the rural areas to the cities in the Third WorldD. the Third Word population is growing at a rate of about 80 million people per year答案：21. C 22. C 23. D 24. C 25. C大学生英语四级考试阅读理解试题及答案解析2There 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 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 individuals 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 theywere giben tesets to measure their intelligence. Marks 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 persons 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 level b.an individuals intelligence is determined only by his enviroment ck of opportunity blocks the growth of intelligence d.changes of enviromentproduce changes in the structure of the brain5.This passage suggests that an individual s I.Q.______. a.can be predicted at birthb.stays the same throuthout his lifec.can be increased by educationd.is determined by his childhood答案：bcbcc大学生英语四级考试阅读理解试题及答案解析3There are three kinds of goals: short-term,medium-range and long-term goals. Short-range goals are those that usually deal with current activities,which we can apply on a daily basis.Such goals can be achieved in a week or less,or two weeks,or possible months.It should be remembered that just as a building is no stronger than its foundation ,out long-term goals cannot amount to very munch without the achievement of solid short-term goals.Upon completing our short-term goals,we should date the occasion and then add new short-term goals that will build on those that have been completed. The intermediate goals bukld on the foundation of the short-range goals.They might deal with just one term of school or the entire school year,or they could even extend for several years.Any time you move a step at a time,you should never allow yourself to become discouraged or overwhelmed. As you complete each step,you will enforce the belief inyour ability to grow adn succeed.And as your list of completion dates grow,your motivation and desire will increase. Long-range goals may be related to our dreams of the future. They might cover five years or more. Life is not a static thing.We should never allow a long-term goal to limit us or our course of action. 1.Our long-term goals mean a lot______.A.if we complete our short-range goalsB.if we cannot reach solid short-term goalsC.if we write down the datesD.if we put forward some plans2.New short-term goals are bulid upon______.A.two yearsB.long-term goalsC.current activitiesD.the goals that have been completed3.When we complete each step of our goals ,______.A.we will win final successB.we are overwhelmedC.we should build up confidence of successD.we should strong desire for setting new goals 4.Once our goals are drawn up,_______.A.we should stick to them until we complete themB.we may change our goals as we have new ideas and opportunitiesC.we had better wait for the exciting news of successD.we have made great decision5.It is implied but not stated in the passage that ______.A.those who habe long-term goals will succeedB.writing down the dates may discourage youC.the goal is only a guide for us to reach our desinationD.every should have a goal答案：adcbc大学生英语四级考试阅读理解试题及答案解析4Today ,as in every other day of the year ,more than 3000 U.S. adlescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime,it can be expected that of these 3000 about 23 will be murdered,30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweithts all other factors, whether voluntary or involuntary, as a cause of death. Since the late 1970s, when daily smoking among high school seniors reached 30 precent , smoking rates among youth have declined . While the decline is impressive ,several important issues must be raised. First, in the past several years,smoking rates among youth have declined very little. Second,in the late 1970s ,smoking among male high school seniors exceeded that among female by nearly 10 percent . The statistic is reversing.Third ,several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent . Finally,thouth significant declines in adolescent smoking have occurred in the past decade,no definite reasons for the decline exist. Within this context,the Naional Cancer Instiute (NCI) began its current effort to determine the most effecive measures to reduce smoking levesl among youth.1.According to the author, the deaths among youth are mainly caused by _____.a.traffic accidentsb.smoking-related deseasec.murderd.all of these2.Every day there are over_____high school strdents who will become regular smoker.a.75b.23c.30d.30003.By "dropout" the author means______.a.students who failed the examinationb.students who left schoolc.students who lost their wayd.students who were driven out of school4.The reason for declining adolescent smoking is that ________.a.NCI has taken effective measuresb.smoking is prevented among high school seniorsc.there are many smokers who have died of cancerd.none of these5.What is implied but not stated by the author is that ________.a.smoking rates among youth have declined very littleb.there are now more female than male smokers among high school seniorsc.high smoking rates are due to the incease in wealthd.smoking at high school are from low socio-economic backgrounds答案：bdbdb【大学生英语四级考试阅读理解试题及答案解析】。

大学英语四级阅读理解试题及答案（四）十六Trees shoul d 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 d oing it unnecessarily than from l eavingthe tree to grow in its own way.First, pruning may be d one to make sure that trees have a d esired 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 preventingthe free movement of air.One result of pruning is that an open wound is l eft on the tree and this provides an easy entry for disease, but itis a wound that will heal. Often there is a race between the healing and the d esease as to whether the tree will live or die, so that there is a period when the tree is at risk. It shoul d be the aim of every gardener to reduce which has been pruned smooth and clean, for healing will be sl owed down by roughness. You shoul d all ow 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 l eaves and also it is very unlikely that the cuts yu make will bl eed. If this does happen,it is, of course,impossible to paint themproperly.1.Pruning shoul d be d one to ______.a.make the tree grow tall erb.improve the shape of the treec.get rid of the small branchesd.make the small branches thicker2.Trees become unhealthy if the gardener ______.a.all ows 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 possibl ec.occasionally when necessaryd.regular every winter5.What was the author's purpose when writing thispassage?a.To give pratical instruction for pruning a tree.b.To give a general d escription of pruningc.To explain how trees d evel op diseasesd.To discuss different methods of pruning.答案：babca十七On Thursday afternoon Mrs. Carke, dressed for going out, took her handbag with her money and her key in it, pulled the door behind her to lock it and went to the over 60s 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 of forced entry.Over a cup of tea she wondered whether someone might have a key that fitted her 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 she went 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. Clarkeraised the kettle and poured 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 againb.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 causes snowblindnenss. Yet, dark glasses or not , they find themselves suffering from headaches and watering eyes,and even snowblindness,when exposed to several hours of "snow light" .The United States Army has now determined that glare from snow does not cause snowblindness in troops in a snow-covered country.Rather, a man's eyes frequently find nothing to foucs on in a broad expanse of barren snow-covered terrain. So his gaze continually shifts and jumps back and forth over the entire landscape in search of tsomething to look at. Finding nothing, hour after hour, the eyes never sotp searching and the eyeballs become sore and the eye muscles ache. Nature offsets this irritation by producing more and fluid which covers the eyeball. The fluid coversthe eyeball in increasing quantity until vision blurs, then is obsured,and the result is total, even 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,the men can cross the snow without becoming hopelessly snowblind or lost. In this way the problem of crossing a solid white terrain is overcome.1.To prevent headaches, watering eyes and blindness caused by the glare from snow, dark glasses are_____.a.indispensibleefulc.ineffectived.available2.When the eyes are sore tears are produced to ________.a.clear the visionb.remedy snowblindnessc.ease the irritationd.loosen the muscles3.Snowblindness may be avoided by_______.a.concentrating to the solid white terrainb.searching for something to look at in snow-covered terrainc.providing the eyes with something to foucs ond.covering the eyeballs with fluid4.The scouts shake snow from evergreen bushes in order to _______.a.bive the men behind something to seeb.beautify the landscapec.warm themselves in the coldd.prevent the men behind from losing their way5.A suitable title for this passage would be _______.a.snowblindness and how to overcome itb.natrue's cure for snowblindnessc.soldiers in the snowd.snow vision答案：CCCAA十九Water problems in the future will become nore intense and more complex. Our increasing population will tremendously increase urban wastes,primarily sewage. On the other hand, increasing demands for water will decease substantialy the amount of water available for diluting wastes. Rapidly expanding industries which involve more and more complex chemical processes will produce large volumes of liquid wastes, and many of these will contain chemicals which are noxious. To feed our rapidly expanding population, agriculture will have to be intensified. This will involve ever-increasingquantities of agricultural chemicals, From this , it is apparent that drastic steps must be taken immediately to develop corrective measures for the pollution problem.There are two ways by which this pollution problem can be dwindled. The first relates to the treatment of wastes to decrease their pollution hazard. This involves the processing of solid wastes "prior to " disposal and the treatment of liquid 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 uses of waterc.to acquaint the reader with water pollution problemsd.to demostrate various 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 with may mother to do the weekly grocery shopping. On that particular day, I must have found my way to the dairy food department 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 knees inspecting 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 pay for 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 152.Who was to blame for knocking off the stacks of cartons?a.The authorb.The managerc.A womand.The author's mother3.Which of the following statements is not true?a.The woman who knocked off the stacks of cartons was seriously criticized by the manangerb.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 together4.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's willingness to admit mistakesb.anger to the manager for his wrong accusationc.indignation against the woman who knocked off the stacks of cartonsd.reget for the mistake the made in the store答案：ccada。
