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. Man can land on Venus only when_______.a.the algae have done their workb.the atmosphere becomes coolerc.thereis oxygend.it rains there答案：cabdd。

大学英语四级阅读理解试题及答案（四）十六Trees should only be pruned when there is a good and clear reason for doing so and , fortunately,the number of such reasons is small. Pruning involves the cutting away of obergrown and unwanted branches, and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the tree to grow in its own way.First, pruning may be done to make sure that trees have a desired shape or size.The object may be to get a tree of the right height, and at the same time to help the growth of small side branches which will thicken its appearance or give it a special shape. Secondly, pruning may be done to make the tree healthier. You may cut diseaed or dead wood, or branches that are rubbing against each other and thus cause wounds. The health of a tree may be encouraged by removing branches that are blocking up the centre and so preventing the free movement of air.One result of pruning is that an open wound is left on the tree and this providesan easy entry for disease, but itis awound that will heal. Often there is a race between the healing and the desease asto whether the tree will live or die, so that there is a period when the tree is at risk. It should be the aim of every gardener to reduce which has been pruned smooth and clean, for healing will be slowed down by roughness. You should allow the cut surface to dry for a few hurs and then paint it with one of the substances available from garden shops produced especially for this purpose. Pruning is usually without interference from the leaves and also it is very unlikely that the cuts yu make will bleed. If this does happen,it is, of course,impossible to paint them properly.1.Pruning should be done to ______.a.make the tree grow tallerb.improve the shape of the treec.get rid of the small branchesd.make the small branches thicker2.Trees become unhealthy if the gardener ______. a.allows too many branches to grow in the middleb.does not protect them from windc.forces them to grow too quicklyd.damages some of the small side branches3.Why is a special substance painted on the tree? a.To make a wound smoothb.To prevent disease entering a woundc.To cover a rough surfaced.To help a wound to dry4.A good gardener prunes a tree______.a.at intervals throughout the yearb.as quickly as possiblec.occasionally when necessaryd.regular every winter5.What was the author's purpose when writing this passage? a.To give pratical instruction for pruning a tree.b.To give a general description of pruningc.To explain how trees develop diseasesd.To discuss different methods of pruning.答案： babca十七On Thursday afternoon Mrs. Carke, dressed for going out, took her handbag withher money and her key in it, pulled the door behind her to lock it and went to the over60s Club. She always went there on Thursdays. It was a nice outing for an old woman who lived alone.At six o'clock she cane home, let herself in and at once smelt cigarette smoke. Cigarette smoke in her house? How? How? Had someone got in? She checked the back door and the windows. All were locked or fastened, as usual. There was no sign offorced entry.Over a cup of tea she wondered whether someone might have a key that fittedher front door-"a master key"perhaps. So she stayed at home the following Thursday. Nothing happened. Was anyone watching her movements? On the Thursday after that shewent out at her usual time,dressed as usual, but she didn't go to the club. Instead she took a short cut home again, letting herself in through her garden and the back door. She settled down to wait.It was just after four o'clock when the front door bell rang.Mrs. Clarke was making a cup of tea at the time. The bell rang again, and then she heard her letter-box being pushed open. With the kettle of boiling water in her hand, she moved quietly towards the front door. A long piece of wire appeared through the letter-box, and then a hand. The wire turned and caught around the knob on the door-lock. Mrs. Clarke raised the kettle andpoured the water over the hand. There was a shout outside, and the skin seemed to drop off the fingers like a glove. The wire fell to the floor, the hand was pulled back, and Mrs. Clarke heard the sound of running feet.1.Mrs. Clarke looded forward to Thursday because_______. a.she worked at a club on the dayb.she said visitors on Thursdaysc.she visited a club on Thursdayd.a special visitor came on Thursday2.If someone had made a forced entery,_______.a.Mrs.Clarke would have found a broken door or windowb.he or she was still in the housec.things would have been thown aboutd.he or she would have needed a master key3.On the third Thursday Mrs. Clarke went out_______. a.because she didn't want to miss the club again b.to see if the thief was hnging about outsidec.to the club but then changed her mindd.in an attempt to trick the thief4.The lock on the front door was one which_______. a.needed a piece of wire to open itb.could he opened from inside without a keyc.could't be opened without a keyed a knob instead of a key5.The wire feel to the floor_______.a.because Mrs.Clarke refused to open the doorb.when the man's glove dropped offc.because it was too hot to holdd.because the man justwanted to get away答案： cadbd十八Many people believe the glare from snow causessnowblindnenss. Yet, dark glasses or not , they find themselves sufferingfrom headaches and watering eyes,and evensnowblindness,when exposed to several hours of "snow light" . The United States Army has now determined that glare from snow does not cause snowblindness in troops in a snow-covered country.Rather, a man's eyes frequently find nothing to foucs on in a broad expanse of barren snow-covered terrain. So his gaze continually shifts and jumps back and forth over the entire landscape in search of tsomething to look at. Finding nothing,hour after hour, the eyes never sotp searching and the eyeballs become sore and the eye muscles ache. Nature offsets this irritation by producing more and fluid which covers the eyeball. The fluid coversthe eyeball in increasing quantity until vision blurs, then is obsured,and the result is total, even though temporary,snowblindness.Experiments led the Army to a simple method of overcoming this problem. Scouts ahead of a main body of troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape,Even the scouts themselves throw lightweight , dark colored objects ahead on which they too can focus . The men following can then see something.Their gaze is arrested. Their eyes focus on a bush and having found something to see,stop scouring thesnow-blanketed lanscape. By focusing their attention on one object at a time,themen can cross the snow without becoming hopelessly snowblind or lost. 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 complexchemical processes will produce large volumes of liquid wastes, and many of these will contain chemicals which are noxious. To feed our rapidly expanding population,agriculture will have to be intensified. This will involve ever-increasingquantitiesof agricultural chemicals, From this , it is apparent that drastic steps must betaken immediately to develop corrective measures for the pollution problem.There are two ways by which this pollution problem can be dwindled. The first relates to the treatment of wastes to decrease their pollution hazard. This involvesthe processing of solid wastes "prior to " disposal and the treatment of liquid wastes, or efflunets,to permit the reuse of the water or minimize pollution upon final disposal.A second approach is to develop an economic use for all or a part of the wastes. Farm manure is spread in fields as a nutrient or organic supplement . Effluents from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained. Efflunets from other processing plants may also be used as a supplemental source of water. Many industries, such as meat and poultry processing plants, are currently converting former waste products into marketable byproducts. Other industries are potential eonomic uses for waste products.1.The purpose of this passage is ______.a.to alert the reader to the dwindling water supplyb.to explain industrial usesof waterc.to acquaint the reader with water pollution problemsd.to demostratevarious measures to solve the pollution problem2.Which of the following points is NOT INCLUDED in the passage?a.In dustrial development incudes the simplification of complex chemical processes.b.Diluting wastes needs certain amount of waterc.Demands for water will go up along with the expanding populationd.Intensive cultivation of land requires more and more chemicals3.The reader can conclued that________.a.countries of the world will work together on polution problemsb.byproducts from wastes lead to a more prosperous marketplacec.science is making great progress on increasing water suppliesd.some industries are now ,aking economic use of wastes4.The author gives substance to the passage through the use of _______.a.interviews with authorities in the field of water controlsb.opinions and personal observationsc.definitions which clarify important termsd.strong arguments and persuasions5.The words "prior to "(para.2 probably mean______. a.afterb.duringc.befored.beyond答案 :cadbc二十One of the qualities that most people admire in others is the willingness to admit one's mistakes. It is extremely hard sometimes to say a simple thing like "I was wrong about that," and it is even harder to say, "I was wrong , and you were right about that."I had an experience recently with someone admitting to me that he had made a mistake fifteen years ago. He told me he had been the manager of a certain grocery store in the neighbourhood where I grew up, and he asked me if I remembered the egg cartons. Then he related an incident and Ibegan to remember vaguely the incident he was describing.I was about eight years old at the time, and I had gome into the store withmay mother to do the weekly grocery shopping.On that particular day, I must have found my way to the dairy fooddepartment where the incident tood place.There must have been a special sale on eggs that day because there was an impressive display of eggs indozen and half-dozen cartons. The cartons were stacked three or four feet high. I must have stopped in front of a display to admire the stacks.Just then a woman came by pushing her grocery cart and knocked off the stacks of cartons. For some reason, I decided it was up to me to put the display back together, so I want to work. The manager heard the moise and came rushing over to see what had happened. When he appeared, I was on my kneesinspecting some of the cartons to see if any of the eggs were broken, but to him it looked as though I was the culprit. He severely reprimanded me and wanted me to payfor any broken eggs. I protested my innocence and tried to explain, but it did no good. Even though I quickly forgot all about the incident, apparently the manager did not.1.How old was the author when he wrote this article? a.about 8b.about 18c.about 23d.about 15 2.Who was to blame for knocking off the stacks of cartons? a.The author b.The manager c.A woman d.The author's mother 3.Which of the following statements is not true? a.The woman who knocked off the stacks of cartons was seriously criticized by the mananger b.The author was severely critizized by the manager.c.A woman carelessly knocked off the stacks of cartonsd.It was the author who put the display back together 4.Which of the following can serve as the best title for the passage?a.Its Harder to Admit One's Mistakeb.I was once the culpritc.I remember an incidentd.A case of mistaken identity5.The tone of the article expresses the author's_______. a.admiration for the manager'swillingness to admit mistakes b.anger to the manager for his wrong accusationc.indignation against the woman who knocked off the stacks of cartonsd.reget forthe mistake the made in the store答案： ccada。

大学英语四级快速阅读测试题及答案
Directions:In this part,you will have15minutes to go over the passage quickly and answer the questions on Answer Sheet1.For questions1-7,choose the best answer from the four choices marked[A],[B],[C]and[D].For questions8-10,complete the sentences with the information given in the passage.How to Visualize Your SuccessHave you ever heard of visualization(可视化)?Of course you have.Everybody’s heard of visualization and everybody partakes in it whether they realize it or not.How it works though is an altogether different matter.I want to take a closer look today at the mechanics of why visualizing works without necessarily delving into concepts and theories that cannot be proven.The brain has great difficulty in distinguishing between what’s true and what’s imagined.There is an off-cited(经常被引用的)example of an experiment conducted by Austrahan Psychologist,Alan Richardson.He took some basketball players and split them into3 equal groups.One group was told to practice their free throw technique twenty minutes per day. The next group was told to spend twenty minutes per day visualizing,but not attempting free throws,and the final group wasn’t allowed to either practice or visualize.At the end of the test period the group that had done nothing remained as they were,but both the other groups showed similar degrees of improvement,The people who only visualized playing basketball were able to perform almost as well as the ones who had actually practiced."How can that be so?"Firstly,the people practicing would miss some shots.Each time they missed they had in effect,practiced how to miss.The people that were visualizing would be hitting every basket so they were building up the feelings and memory of how to be successful.Forging a Path through a MeadowImagine walking home from a new job.You suddenly realize that there is a meadow of long grass that will cut20minutes off your walk.If you live in New York you’re going to need a great imagination for this one.The first few times you can barely see which way you had walked the previous day. However,after10or20times you can clearly see a pathway starting to form,and after100times all the grass is worn away and there’s a farmer with a shotgunand large dog waiting for you at the end.Let’s presume our gun-toting friend is a big softie and he allows you to use that route as long as you want.What are the odds that next time you try a slightly different direction?Slim to none would be my guess.After all,you know this way works and you have a lovely easy path.On the other hand,if Farmer Giles starts taking pot shotsat you and sportingly lets the dog try and shoot you too,before releasing it to sink its gnashers into your rear end,then you’ll probably find a new way home once you’re released fromhospital.The next time you’re walking home you opt against reacquainting yourself with Fido and spot another meadow further along the road.The same process then begins to take place only this time the original path you made has started to grow back.How We Create a Path in Our Mind That is what happens when we form thoughts in our mind.The first time we have a new thought it is a weakling(虚弱者)of a thought that has sand kicked in its face by stronger thoughts and beliefs.Each time you re-think it though it grows instrength as the physical pathway becomes more and more well-defined.Not only that,but if it is a belief that contradicts one you already hold,the older belief starts to atrophy and die.This also explains why we have the same thoughts over and over again and why people have difficulty snapping negative loops(循环)of thinking.The pathway has been established and it’s just easier to continue following it than trying to thinkabout something new and form a new connection in the brain.Making Visualization Work for YouVisualization is an incredibly successful and simple way of speeding up the process by fooling the unconscious into believing that you have already done something before you have. That’s what the basketball visualizers were doing,fooling their own unconscious into thinking they know how to hit basket after basket.Of course this in and of itself will not turn you into an NBA star,you do actually have to practice as well,but it will help you succeed more quickly.All you need to do to be successful at this is to visualize yourself doing something,as you would like to do it.Profound stuff,huh?Seriously though,that is all there is to it.How long you do it each day will affect the speed of change and it’s reallynot advisable visualizing your success for20minutes per day and then spending10 hours worrying about failing and replaying negative stuff in your head.It kind of defeats the object.You can also incorporate the"fake it till you make it"method in with your visualization to help speed up the process.This is simply a matter of pretending you are already proficient at something before you really are.Again,it’s simply a way of tricking your unconscious and getting it to do what you want it to do.Some people have difficulty with this process and tell me it’s being unrealistic.Well yeh,maybe they’re right,but who cares?If you want to be shackled by the chains of realism then go ahead,knock yourself out,but let me tell you this.There are few highly successful people out there that haven’t used this method or visualization at one time or another.In fact,successful people don’t care too much for reality;it just gets in the way and slows them down.What about you?注意：此部分试题请在答题卡1上作答；8-10题在答题卡1上。
大学英语四级阅读模拟题及答案(3篇)
大学英语四级阅读模拟题及答案阅读1空调的危害Although many of us may feel air-conditioners bring relief from hot,humid or polluted outside air,they pose many potential health hazards.Much research has looked at how the movement of air inside a closed environment---such as an office building---can spread disease or expose people in the building to harmful chemicals.One of the more widely publicized dangers is that of Legionnaire’s disease,which was first recognized inthe1970s.This was found to have affected people in buildings with air-conditioning systems in which warmair pumped out of the system’cooling towers was somehow sucked back into the air intake(通风口),in mostcases due to poor design.The warm air,filled with bacteria,was combined with cooled,conditioned air andwas then circulated around various parts of the building. Studies showed that even people outside such buildings were at risk if they walked past air exhaust pipes.Large air-conditioning systems add water to the air they circulate by means of humidifiers(湿度调节器).Inolder systems,the water used for this process is kept in special reservoirs,the bottoms of which providebreeding grounds for bacteria which can find their way into the ventilation (通风)system.The risk to human health from this situation has been highlighted by the fact that the immune systems(免疫系统)of approximately half of workers in air-conditioned office buildings have developed the ability to fight off the organisms found at the bottom of system reservoirs. But chemicals called“biocides”are added to reservoirs to make them germ-free,and they are dangerous in their own right in sufficient quantities,as they often contain compounds strongly linked to cancers.Finally,it should be pointed out that the artificial climatic environment created byair-conditioners canalso affect us.In a natural environment,whether indoor or outdoor,there are small variations in temperature and humidity.Indeed,the human body has long been accustomed to these normal changes.In an air-conditioned living or working environment,however,body temperatures remain well under37℃,our normal temperature.This leads to a weakened immune system and thus greater exposure to diseases such as colds and flu.练习题：Choose correct answers to the question:1.What do we know about Legionnaire's disease from the passage?A.It was the most widely concerned office hazard.B.It can affect people both inside and outside the building.C.It happens only in air-conditioned office buildings.D.It does not develop in well-designed buildings.2.In the old air-conditioned systems,bacteria first develop______.A.in the reservoirsB.in the ventilation systemc.in the humidifiersD.in the air intake3.The fact that about half of workers developed the ability to fight off the bacteria may__.A.relieve people’s worry about the danger caused by the bacteriaB.help people find an effective way to get rid of the bacteriaC.reflect the serious danger brought by the bacteriaD.cause serious disease such as cancers to people4.The author most probably wants the readers to treat biocides with an attitude of_.A.cautionB.trustC.enthusiasmD.criticism5.The last paragraph implies that our immune system can be weakened when_•A.we live in an artificial climatic environmentB.there are variations in temperature and humidityC.our body temperatures often remain not high enoughD.we are often exposed to diseases such as colds and flu答案解析：1.[B]事实细节题。

Students can now access a wealth of information at their fingertips, and teachers can employ various tools to enhance the learning experience.However, there are also concerns about the over-reliance ontechnology.

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. According to this passage, the way people treat newborns _____.A) is a sign of their customsB) is an indication of their level of knowledgeC) symbolizes their social systemD) varies from culture to culture22. The expression, "to cut the cord", is used to show that _____.A) children dont like their parentsB) parents dont feel close to their childrenC) parents would not like to live together with their childrenD) independence from ones family is an important personal goal in USA23. Children who are "tied to the apron strings" _____.A) are caught in their mothers apronsB) must always wear an apron when they eatC) are very dependent on their mothersD) are independent from their parents24. American people often let their children work for money outside the home at a very early age because _____.A) children have to earn money to help the familyB) they need more moneyC) they want them to begin establishing autonomyD) children have to save money for future use25. 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习题及答案
大学英语四级阅读理解习题及答案高校英语四级阅读理解习题及答案引导语：英语六级阅读理解难度不一般，以下是我整理的高校英语四级阅读理解习题及答案，欢迎参考!Questions 21 to 25 are based on the following passage:It is simple enough to say that since books have classes fiction, biography, poetrywe should separate them and take from each what it is right that each should give us. Yet few people ask from books what books can give us. Most commonly we come to books with blurred and divided minds, asking of fiction that it shall be true, of poetry that it shall be false, of biography that it shall be flattering, of history that it shall enforce our own prejudices. If we could banish all such preconception when we read, that would be an admirable beginning. Do not dictate to your author; try to become him. Be his fellow worker and accomplice(同谋). If you hang back, and reserve and criticize at first, you are preventing yourself from getting the fullest possible value from what you read. But if you open your mind as widely as possible, then signs and hints of almost imperceptible finess(委婉之处), from the twist and turn of the first sentences, will bring you into the presence of a human being unlike any other. Steep yourself in this, acquaint yourself with this, and soon you will find that your author is giving you, or attempting to give you, something far more definite. The thirty two chapters of anovelif we consider how to read a novel firstare an attempt to make something as formedand controlled as a building but words are more impalpable than bricks, reading is a longer and more complicated process than seeing. Perhaps the quickest way to understand the elements of what a novelist is doing is not to read, but to write; to make your own experiment with the dangers and difficulties of words. Recall, then, some event that has left a distinct impression on youhow at the corner of the street, perhaps, you passed two people talking. A tree shook; an electric light danced; the tone of the talk was comic, but also tragic; a whole vision, an entire conception, seemed contained in that moment.21.What does the author mean by saying "Yet few people ask from books what books can give us.'?A.The author means that lots of people read few books.B.The author thinks that readers have only absorbed part of knowledge in books.C.The author holds that few people have a proper idea about what content some kind of books should include.D.The author considers that readers can scarcely understand most of the books.22.According to the passage, which of the following statement is right?A.A reader should find some mistakes when he is reading.B.The more difficult a book is, the more you can get fromit.C.To read something is easier than to watch something.D.One should be in the same track with the writer when he is reading.23.What is the possible meaning of "impalpable' (Paragraph 2) in the passage?A.Clear.B.Elusive.C.Delicate.D.Precise.24.Whats the main idea of this passage?A.The importance of reading.B.The proper way to read.C.How to get most from one book.D.The characters of a good book.25.When a writer is writing he often get the whole conception ____.A.after a long times thinkingB.through an instant inspirationC.according to his own experienceD.by way of watching the objects attentively参考答案：21.答案C。

For questions 1-7, choose the best answer from the four choices marked A), B), C) and D). For questions 8-10, complete the sentences with the information given in the passage.Work-life balance: Ways to restore harmony and reduce stressFinding work-life balance in today’s frenetically (疯狂) paced world is no simple task.Spend more time at work than at home, and you miss out on a rewarding personal life. Then again, when you face challenges in your personal life, such as caring for an aging parent or coping with marital problems, concentrating on your job can be difficult.Whether the problem is too much focus on work or too little, when your work life and your personal life feel out of balance, stress — along with its harmful effects — is the result.The good news is that you can take control of your work-life balance — and give yourself the time to do the things that are most important to you. The first step is to recognize how the world of work has changed. Then you can evaluate your relationship to work and apply some specific strategies for striking a healthier balance.How work invades your personal lifeThere was a time when employees showed up for work Monday through Friday and worked eight- to- nine-hour days. The boundaries between work and home were fairly clear then. But the world has changed and, unfortunately, the boundaries have blurred for many workers. Here’s why:●Global economy. As more skilled workers enter the global labor market and companies outsource or move more jobs to reduce labor costs, people feel pressured to work longer and produce more just to protect their jobs.●International business. Work continues around the world 24 hours a day for some people. If you work in an international organization, you might be on call around the clock for troubleshooting or consulting.●Advanced communi cation technology. Many people now have the ability to work anywhere — from their home, from their car and even on vacation. And some managers expect this.●Longer hours. Employers commonly ask employees to work longer hours than they’re scheduled. Ofte n, overtime is mandatory (强制性的). If you hope to move up the career ladder, you may find yourself regularly working more than 40 hours a week to achieve and exceed expectations.●Changes in family roles. Today’s married worker is typically part of a dual-career couple, which makes it difficult to find time to meet commitments to family, friends and community.Married to your workIt can be tempting to rack up the hours at work —especially if you’re trying to earn a promotion or some extra money for a child’s education or a dream vacation. For others, working more hours feels necessary in order to manage the workload.But if you’re spending most of your time at work, your home life will likely pay the price. Consider the pros and cons of working extra hours on your work-life balance:●Fatigue. Your ability to think and your eye-hand coordination decrease when you’re tired. This means you’re less productive and may make more mistakes. These mistakes can lead to injury or rework and negatively impact your professional reputation.●Family. You may miss out on important events, such as your child’s first bike ride, your father’s 60th birthday or your high-school reunion. Missing out on important milestones may harm relationships with your loved ones.●Friends. Trusted friends are a key part of your support system. But if you’re spending time at the office instead of with them, you’ll find it difficult to nurture those friendships.●Expectations. If you regularly work extra hours, you may be g iven more responsibility. This could create a never-ending and increasing cycle, causing more concerns and challenges.Sometimes working overtime is important. If you work for a company that requires mandatory overtime, you won’t be able to avoid it, bu t you can learn to manage it. Most importantly, say no when you’re too tired, when it’s affecting your health or when you have crucial family obligations.Striking the best work-life balanceFor most people, juggling (巧妙处理) the demands of career and personal life isan ongoing challenge. With so many demands on your time —from overtime to family obligations — it can feel difficult to strike this balance. The goal is to make time for the activities that are the most important to you.Here are some ideas to help you find the balance that’s best for you:●Learn to say no. Whether it’s a co-worker asking you to spearhead (充当先锋) an extra project or your child’s teacher asking you to manage the class play, remember that it’s OK to respectfully say no. When you quit doing the things you only do out of guilt or a false sense of obligation, you’ll make more room in your life for the activities that are meaningful to you and bring you joy.●Leave work at work. Make a conscious decision to separate work time from personal time. When with your family, for instance, turn off your cell phone and put away your laptop computer.●Manage your time. Organize household tasks efficiently. Do one or two loads of laundry every day, rather than saving it all for your day off. A weekly family calendar of important dates and a daily list of to-dos will help you avoid deadline panic. If your employer offers a course in time management, sign up for it.●Get enough sleep. There’s nothing as stressful and potentially d angerous as working when you’re sleep-deprived. Not only is your productivity affected, but also you can make costly mistakes. You may then have to work even more hours to make up for these mistakes.●Communicate clearly. Limit time-consuming misunderstandings by communicating clearly and listening carefully. Take notes if necessary.●Nurture yourself. Set aside time each day for an activity that you enjoy, such as walking, working out or listening to music.●Set aside one night each week for recre ation.

And we can expect the rate of change to accelerate rather than slow down within our lifetime. The developments in technology are bound to have a dramatic effect on the future of work. By 2010, new technology will have revolutionized communications. People will be transmitting messages down telephone lines that previously would have been sent by post. Not only postmen but also clerks and secretaries will vanish in a paper-free society. All the routine tasks they perform will be carried on a tiny silicon chip so that they will be as obsolete(已废弃的) as the horse and cart after the invention of the motorcar. One change will make thousands, if not millions, redundant.Even people in traditional professions, where expert knowledge has been the key, are unlikely to escape the effects of new technology. Instead of going to a solicitor, you might go to a computer that is programmed with all the most up-to-date legal information. Doctors, too, will find that an electronic competitor will be able to carry out a much quicker and more accurate diagnosis and recommend more efficient courses oftreatment. In education, teachers will be largely replaced by teaching machines far more knowledgeable than any human being. Most learning will take place in the home via videoconferencing. Children will still go to school though, until another place is created where they can make friends and develop social skills.练习题：Choose correct answers to the question:1.According to the writer, the rate of change in technology______.A.will remain the sameB.will slow downC.will speed upD.can not be predicted2.The writer expects that by 2020 new technology will have revolutionized communications and ____A.people needn’t telephone each otherB.the present postal system will have disappearedC.people will no longer send lettersD. the postmen will have been replaced by silicon chip.3.The word “they” (Line 6，Para. 1) refers to _____.A. the tiny silicon chipsB.the letter written on paperC. the postmen, clerks and secretariesD.the routine tasks performed by the postmen4.From the second paragraph, we can infer that _____A. professionals won’t be affected by new technologyB.doctor won’t be as efficient by the postmenC. computers cannot replace lawyersD.experts will lose job in the future5.In the writer’s view, _______.A.people should get prepared for the futureB.there exists no real threat of unemploymentC.the advance of technology is not desirableD.machines will have control over men答案解析1.[C] 事实细节题。

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

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

They also hope their children learn to read quickly and easily, so that they’re ready for the demands put on them by school and the world.Kids want to learn how to read, but they also crave entertainment, whether it’s quiet and passive or dynamic and interactive. The aims of the Story Reader line of electronic books are to entertain children and to introduce them to the processof learning how to read in a gentle and enjoyable way. In this article, we’ll show you how Story Reader works and if it accomplishes that goal.Story Reader is a compact, roughly 12-inch-by-12-inch plastic case (with a carrying handle ) that opens to reveal an actual book that fits snugly into the Reader itself. Story Reader’s core feature is that it "reads" the book aloud to a child as he follows along. The child turns the pages when prompted by the Story Reader or at his own pace.Books have both text and illustrations. The electronic book responds to the child’s wishes. The Story Reader speaks the text for the current page. If the child turns back a few pages, the Reader recognizes that page and reads it again. Kids react well to this interactivity because it instills a sense of cuntrol over the story.There are Three Story Reader ProductsThe basic Story Reader, introduced in 2003, is as described above and is intended for kids three years of age and older.Each book has a small companion cartridge that slides into a port on the case and contains the audio encoded into its memory for the story.The device has a volume control but no on/off switch--a deliberate choice so kids can simply open it up and begin reading. It takes four AAA batteries (or operates on household current with an optional adaptor) and retails for around $20.Find out more information about the more than 60 titles at the Story Reader website.Early in 2006, Publications International, Ltd.--Story Reader’s publisher--introduced My First Story Reader, designed for newborns to kids up to age three. As with the original, a narrator reads the story aloud, this time from a 12-page book made from a heavier paperstock that includes sound effects and music to enliven the experience.My First Story Reader features two play modes, one with narration, the other that asks questions about the images on each page. The child can press any of three buttons to answer basic questions about shapes and colors. The last two pages ofeach My First Story Reader book features a sing-along rhyming melody. My First Story Reader retails for about $20.Late in 2006, Publications International introduced a video version of Story Reader called Story Reader Video Plus for kids up to the age of seven. Retailing for about $35, it combines a stand-alone Story Reader with an "Animated Story Mode"that plays through your television and includes a "Learning Game Mode".The Animated Story Mode works just as it sounds--when you connect it to your television through color-coded cables, the story appears on screen and changes as your child turns the pages. Kids get to the Learning Game Mode by turning to thelast page of the book. There, they can choose from five educational games. While it depends on the story, generally there are pattern games, memory games, and platform games. Similar to Nintendo games like Super Mario Brothers, in a platform game the child uses the included controller to guide him through the environment and conquer obstacles.Story Reader Video Plus isn’t a video game, technically, and Publications International bills the Story Reader line more as electronic books than toys. This reassures many parents, and it’s why Story Reader is sold in bookstores and in the book section of major retailers.What about the Educational Underpinnings of Story Reader?Studies show an alarming decline in reading rates among all age groups in America, especially among the young.Children are bombarded on a daily basis with multiple forms of entertainment that compete with traditional learning.Kids naturally emulate the adults in their lives, and seeing their parents and other family members enjoy reading is a powerful motivator. Establishing and keeping a Read-At-Home Night helps families spend time together and helps form lifelong reading habits in children.Here’s how you do it:·Set aside one night a week in your household and call it "Read-At-Home Hour"--or anything you prefer. Establish a time allotment that works for your family, for example, 30 minutes or an hour.·Minimize interruptions from the TV, computer, and video games--and turn on the telephone answering machine.·Choose one book for the entire family to read aloud together, or encourage individual family members to choose their own books to read quietly. Electronic books can work in this context, as well.·Finally, sit down, relax, and read.1. The aims of the Story Reader line of electronic books are __[A] to entertain and teach children[B] to play with the child[C] to ease the parents’burden[D] to ease the teachers’burden2. Story Reader’s key characteristic is that __[A] it "reads" the book which the child likes[B] it "reads" the book while the child plays[C] it "reads" the book while the child follows along[D] it "reads" the book while the parent works3. Children __ are suitable users of the basic Story Reader.[A] up to six months old[B] up to age one[C] up to age two[D] up to age three4. The basic Story Reader for sale is about __[A] 12 dollars[B] 20 dollars[C] 35 dollars[D] 60 dollars5. My First Story Reader is characteristic with[A] two play modes[B] three play modes[C] four play modes[D] five play modes6. Story Reader Video Plus is a video version of Story Reader designed for __[A] newborns to kids up to age three[B] newborns to kids up to age seven[C] children up to the age of five[D] children up to the age of seven7. How many games can children choose from the Animated Story Mode?[A] four[B] five[C] six[D] seven8. If the Story Reader speaks the text for the current page, but the child tums back a few pages, it will __________9. Late in 2006, we can infer that there were Story Reader products___________.10. Like Super Mario Brothers, children in a platform game use the included controllers to__________（三）Reading Comprehension (Skimming and Scanning) (15 minutes)Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions on Answer Sheet 1. For questions 1-7, choose the best answer from the four choices marked [A], [B], [ C ]and [D]. For questions 8-10, complete the sentences with the information given in the passage.The Right Amount of EnergyWe all enjoy being around people with energy. They inspire us. They are stimulating, fun, and uplifting. An energetic person has passion in his voice, a bounce in his step, and a smile on his face. Energy makes a person likable, and likability is akey ingredient in persuasive communications. Many business professionals underestimate the energy level required to generate enthusiasm among their listeners. But electrifying speakers bring it. They have an energy that is several levels higher than the people they are attempting to influence.Most business professionals could use an energy boost for public speaking situations such as Webinars, podcasts, staff meetings, conference calls, and television and radio interviews. Each of these opportunities requires a higher level of energythan would normally be appropriate if you were just chatting to someone in the hallway. But how do you project the right level of vigor without seeming over the top? By weighing yourself on an energy scale. And on this scale, more is better.The Energy ScaleRecently I helped an executive prepare for his first major presentation in his new role."Tell me where your energy is right now on a scale of one to ten," I asked. "One being fast asleep and ten being Jim Cramer on Mad Money. You know, the guy who’s yelling and gesturing wildly on his CNBC show. Where are you now?""A three," the speaker replied."OK, what would it feel like to be a seven, eight or nine? Give it a try," I suggested.If they’re being honest, most presenters place themselves at a three to six on the energy scale. That means there is plenty of room to boost your energy while not appearing too zany. But keep in mind, once you hit a ten or higher, you could be the next YouTube (GOOG) hit--which is not necessarily your top objective! Here are several surefire strategies to boost your energy presence.1. Practice leaving your comfort zone.Record several minutes of your presentation as you would normally deliver it: Play it back, preferably with someone else watching and listening as well. Ask yourself and the observer, where am I on the energy scale? Now try it again. This time,break out of your comfort zone. Ham it up. Raise your voice. Use big gestures. Put a big smile on your face. Get to a point where you would feel slightly awkward and uncomfortable. Now watch it. Most likely your energy level will be far more engaging and still remain appropriate fur the situation.2. Smile and have fun.Why do most people seem to enjoy Virgin entrepreneur Richard Branson? Because the guy has fun and it shows. He always has a warm, engaging smile on his face. Of course, you can argue that it’s easy to walk around with a smile when you’re worth $4 billion! But seriously, smile. Itwon’t hurt and it will make you more likable. Most business professionals don’t smile as much as they should during presentations. I’m helping some executives prepare for CES, the big Consumer Electronics Show in January where they will announce new products. They get so caught up in the slides and what they’re going to say ( as they should during preparation ), they forget that new products bring joy to their consumers. In most cases--with the exception of bad news, of course--the first and last thing you say to yourself before launching into your presentation should be, "Have3. Get your body moving.Many people are uncomfortable using expansive hand gestures. Don’t be. I spoke to David McNeill at the University of Chicago, who is known for his research into gesture and speech. He says that clear, confident speakers use hand gestures and that the gestures leave a positive impression on listeners.He went on to say that using gestures will help you speak better because for most of us it takes effort not to use gestures.Don’t be afraid of using your hands.AOL’s (TWX) is one of my favorite video search engines. I use it to retrieve clips of business speakers to study their body language. Symantec’s (SYMC) John Thompson, Oracle’s (ORCL) Larry Ellison, Cisco’s (CSCO) John Chambers, and eBay’s (EBAY) Meg Whitman are excellent examples of people with confident, energetic body language.4. Study TV and radio personalities.Stars of television and radio who score high on the likability scale have high-energy personalities. I had a conversation with Suze Orman over the phone a couple of years ago and remember it to this day. Her energy comes right through the speaker. What you see on her CNBC show is what you get behind the scenes. High energy. The other day I watched Food Network (SSP) star Rachael Ray sign books at a mall where I happened to be shopping. Sometimes critics poke fun at her"perky" personality and phrases like "yum-o," but the fact is she has energy and millions of viewers enjoy it. The networkmorning-show hosts are typically chosen for their energetic personalities. Today’s Matt Lauer on NBC (GE) and The EarlyShow’s Julie Chen on CBS (CBS) are excellent examples, but there are many others on morning television.Remember, maintaining an energetic presence is very difficult to do unless you’re involved with something you enjoy. If you are truly passionate about your company, product, or service, then show it. Speak with energy and vitality. Your listenerswill love you for it.l.

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

2020年大学英语四级考试阅读理解真题及答案详解（全套）
2020年大学英语四级考试阅读理解真题及答案详解（全套）大学英语四级考试阅读理解真题及答案（全套）大学英语四级考试阅读理解真题【阅读】Section CDirections：There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 56 to 60 are based on the following passage.In recent years, a growing body of research has shown that our appetite and food intake are influenced by a large number of factors besides our biological need for energy, including our eating environment and our perception of the food in front of us.Studies have shown, for instance, that eating in front of the TV (or a similar distraction) can increase both hunger and the amount of food consumed. Even simple visual cues, like plate size and lighting, have been shown to affect portion size and consumption.A new study suggested that our short-term memory also may play a role in appetite. Several hours after a meal, people's hunger levels were pre dicted not by how much they’d eaten but rather by how much food they'd seen in front of them—in other words, how much they remembered eating.This disparity (盖弃）suggests the memory of our previousmeal may have a bigger influence on our appetite than the actual size of the meal, says Jeffrey M. Brunstrom, a professor of experimental psychology at the University of Bristol."Hunger isn't controlled solely by the physical characteristics of a recent meal. We have identified an independent role for memory for that meal，" Brunstrom says. "This shows that the relationship between hunger and food intake is more complex than we thought."These findings echo earlier research that suggests our perception of food can sometimes trick our body’s response to the food itself. In a 2011 study, for instance, people who drank the same 3S0-calorie (卡路里）milkshake on two separate occasions produced different levels of hunger-related hormones （荷尔蒙），depending on whether the shake’s label said it contained 620 or 140 calories. Moreover, the participants reported feeling more full when they thought they'd consumed a higher-calorie shake.What does this mean for our eating habits? Although it hardly seems practical to trick ourselves into eating less, the new findings do highlight the benefits of focusing on our food and avoiding TV and multitasking while eating.The so-called mindful-eating strategies can fight distractions and help us control our appetite, Brunstrom says.注意：此部分试题请在答题卡2上作答。

Directions:In this part,you will have15minutes to go over the passage quickly and answer the questions on Answer Sheet1.For questions1-7,choose the best answer from the four choices marked[A],[B],[C]and[D].For questions8-10,complete the sentences with the information given in the passage.How to Visualize Your SuccessHave you ever heard of visualization(可视化)?Of course you have.Everybody’s heard of visualization and everybody partakes in it whether they realize it or not.How it works though is an altogether different matter.I want to take a closer look today at the mechanics of why visualizing works without necessarily delving into concepts and theories that cannot be proven.The brain has great difficulty in distinguishing between what’s true and what’s imagined.There is an off-cited(经常被引用的)example of an experiment conducted by Austrahan Psychologist,Alan Richardson.He took some basketball players and split them into3 equal groups.One group was told to practice their free throw technique twenty minutes per day. The next group was told to spend twenty minutes per day visualizing,but not attempting free throws,and the final group wasn’t allowed to either practice or visualize.At the end of the test period the group that had done nothing remained as they were,but both the other groups showed similar degrees of improvement,The people who only visualized playing basketball were able to perform almost as well as the ones who had actually practiced."How can that be so?"Firstly,the people practicing would miss some shots.Each time they missed they had in effect,practiced how to miss.The people that were visualizing would be hitting every basket so they were building up the feelings and memory of how to be successful.Forging a Path through a MeadowImagine walking home from a new job.You suddenly realize that there is a meadow of long grass that will cut20minutes off your walk.If you live in New York you’re going to need a great imagination for this one.The first few times you can barely see which way you had walked the previous day. However,after10or20times you can clearly see a pathway starting to form,and after100times all the grass is worn away and there’s a farmer with a shotgunand large dog waiting for you at the end.Let’s presume our gun-toting friend is a big softie and he allows you to use that route as long as you want.What are the odds that next time you try a slightly different direction?Slim to none would be my guess.After all,you know this way works and you have a lovely easy path.On the other hand,if Farmer Giles starts taking pot shotsat you and sportingly lets the dog try and shoot you too,before releasing it to sink its gnashers into your rear end,then you’ll probably find a new way home once you’re released fromhospital.The next time you’re walking home you opt against reacquainting yourself with Fido and spot another meadow further along the road.The same process then begins to take place only this time the original path you made has started to grow back.How We Create a Path in Our Mind That is what happens when we form thoughts in our mind.The first time we have a new thought it is a weakling(虚弱者)of a thought that has sand kicked in its face by stronger thoughts and beliefs.Each time you re-think it though it grows instrength as the physical pathway becomes more and more well-defined.Not only that,but if it is a belief that contradicts one you already hold,the older belief starts to atrophy and die.This also explains why we have the same thoughts over and over again and why people have difficulty snapping negative loops(循环)of thinking.The pathway has been established and it’s just easier to continue following it than trying to thinkabout something new and form a new connection in the brain.Making Visualization Work for YouVisualization is an incredibly successful and simple way of speeding up the process by fooling the unconscious into believing that you have already done something before you have. That’s what the basketball visualizers were doing,fooling their own unconscious into thinking they know how to hit basket after basket.Of course this in and of itself will not turn you into an NBA star,you do actually have to practice as well,but it will help you succeed more quickly.All you need to do to be successful at this is to visualize yourself doing something,as you would like to do it.Profound stuff,huh?Seriously though,that is all there is to it.How long you do it each day will affect the speed of change and it’s reallynot advisable visualizing your success for20minutes per day and then spending10 hours worrying about failing and replaying negative stuff in your head.It kind of defeats the object.You can also incorporate the"fake it till you make it"method in with your visualization to help speed up the process.This is simply a matter of pretending you are already proficient at something before you really are.Again,it’s simply a way of tricking your unconscious and getting it to do what you want it to do.Some people have difficulty with this process and tell me it’s being unrealistic.Well yeh,maybe they’re right,but who cares?If you want to be shackled by the chains of realism then go ahead,knock yourself out,but let me tell you this.There are few highly successful people out there that haven’t used this method or visualization at one time or another.In fact,successful people don’t care too much for reality;it just gets in the way and slows them down.What about you?注意：此部分试题请在答题卡1上作答；8-10题在答题卡1上。
