As you complete each step,you will enforce the belief in yo ur ability to grow adn succeed.And as your list of completion dates grow,your motivation and desire will increase.Long-range goals may be related to our dreams of the future. They might cover five year s or more. Life is not a static thing.We should never allow a long-term goal to limit us or our course of action.1.Our long-term goals mean a lot__.a.if we complete our short-range goalsb.if we cannot reach solid short-term goalsc.if we write down the datesd.if we put forward some plans2.New short-term goals are bulid upon__.a.two yearsb.long-term goalsc.current activitiesd.the goals that have been completed3.When we complete each step of our goals ,__.a.we will win final successb.we are overwhelmedc.we should build up confidence of successd.we should strong desire for setting new goals4.Once our goals are drawn up,__.a.we should stick to them until we complete themb.we may change our goals as we have new ideas and opportunitiesc.we had better wait for the exciting news of successd.we have made great decision5.It is implied but not stated in the passage that ___.a.those who habe long-term goals will succeedb.writing down the dates may discourage youc.the goal is only a guide for us to reach our desinationd.every should have a goal1/200答案：adcbc2/200The economy of the United states after 1952 was the econnomy of a well-fed,almost fully employed people. Despit occasional alarms, the country escaped any postwar depression a nd lived in a state of boom. A n economic survey of the year 1955, a typical year of th e 1950’s, may be typical as illustrating the rapid economic growth of the decade. The nat ional output was value at 10 percent above that of 1954 (1955 output was estimated at 392 billion dollars). The production of manufacturers was about 40 percent more than it had averaged in the years immediately following World War 2. The country’s business spent about 30billion dollars for new factories and machinery. National income available for sp ending was almost a third greater than it had been it had been in 1950. Consumers spent about 256 billion dollars; that is about 700 million dollars a day ,or about twenty-five m illion dollars every hour , all round the clock. Sixty-five million people held jobs and onl y a little more than two million wanted jobs but could not find them . Only agriculture c omplained that it was not sharing in the room. To some observers this was an ominous e cho of the mid-1920’s . As farmer’s shre of their products declined , marketing costs rose. But there were , among the observers of the national economy, a few who were not as confident as the majority . Those few seemed to fear that the boom could not last and w ould eventually lead to the oppsite-depression.1. What is the best title of the passage?a. The Agriculat ural Trends of 1950’sb. The Unemployment Rate of 1950’sc. U.S. Economy in the 50’sd. The Federal Budget of 19522. In Line 4 , the word “boom” could best be replaced by______.a. nearby explosionb. thunderous noisec. general public supportd. rapid economic growth3. It can be inferred the national from the passage that most people in the United States in 1955 viewed the national economy with an air of _________.a. confidenceb. confusionc. disappointmentd. suspicion4. Which of the following w ere LEAST satisfied with the national economy in the 1950’s?a. Economistsb. Frmaersc. Politiciansd. Steelworkers5.

How much was it ?a. 60％b. 50％c. 33％d. 90％2/200答案：cdabc3/200Women are also underrepresented in the administration and this is because there are so fe w women full professors. In 1985,Regent Beryl Milburn produced a report blasting the Un iversity of Texas System adminitration for not encouraging women.The University was rate d among the lowest for the system.In a 1987 update ,Milburn commended the progress th at was made and called for even more improvement.One of the positive results from her study was a System-wide program to inform women of available administrative jobs.College of Communication Associate Dean Patrica Witherspoon,said it is important that wo man be flexible when it comesto relocating if they want to rise in the ranks.Although a woman may face a chilly climate on campus , many times in order for her to succeed , she must rise above the problems around her and concentrate on her work. Until women make up a greater percentage of the senior positions in the University and a ll academia,inequities will exist."Women need to spend their energies and time doing scholarly activities that are importan t here at the University." Spirduso said. "If they do that will be successful in this system. If they spend their time in little groups mourning the sexual discrimination that they think exists here, they are wasting valuable study time."1.According to Spirduso,women need to ____.a.produce a report on sexual discriminationb.call for further improvement in their working conditionsc.spend their energies and time fighting against sexual discriminationd.spend more time and energy doing scholarly activities2.From this passage ,we know that _____.a.there are many women full professors in the University of Texasb.women play an important part in adminitrating the Universityc.the weather on the campus is chillyd.women make up a small percentage of the senior positions in the University3.Which of the following statements is true?a.the number of women professors in the University in 1987 was greater than that of 198 5b.the number of women professors in the University in 1987 was smaller than that of 198 5c.the number of women professors was the same as that of 1985d.more and more women professors thought that sexual discrimination did exit in the Univ ersity4.One of the positive results from Milburn's study was that _____.a.women were told to con centrate on teir workb.women were given information about available administrative jobsc.women were encouraged to take on all the administrative jobs in the Unversityd.women were encouraged to do more scholarly activities5. The title for this passage should be _______.a.The University of Texasburn's Reportc.Women Professorsd.Sexual Discrimination in Academia3/200答案：ddabd4/200Today ,as in every other day of the year ,more than 3000 U.S. adlescents will smoke thei r first cigarette on their way to becoming regular smokers as adults. During their lifetime,i t can be expected that of these 3000 about 23 will be murdered,30 will die in traffic acci dents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweithts all other factors, whether voluntary or involuntar y, as a cause of death.Since the late 1970s, when daily smoking among high school seniors reached 30 precent , smoking rates among youth have declined . While the decline is impressive ,several impo rtant issues must be raised.First, in the past several years,smoking rates among youth have declined very little. Secon d,in the late 1970s ,smoking among male high school seniors exceeded that among female by nearly 10 percent . The statistic is reversing.Third ,several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent .Finally, thouth significant declines in adolescent smoking have occurred in the past decade, no definite reasons for the decline exist. Within this context,the Naional Cancer Instiute (NCI) began its current effort to determine the most effecive measures to reduce smoking levesl among youth.1.According to the author, the deaths among youth are mainly caused by _____.a.traffic accidentsb.smoking-related deseasec.murderd.all of these2.Every day there are over_____high school strdents who will become regular smoker.a.75b.23c.30d.30003.By "dropout" the author means______.a.students who failed the examinationb.students who left schoolc.students who lost their wayd.students who were driven out of school4.The reason for declining adolescent smoking is that ________.a.NCI has taken effective measuresb.smoking is prevented among high school seniorsc.there are many smokers who have died of cancerd.none of these5.What is implied but not stated by the author is that ________.a.smoking rates among youth have declined very littleb.there are now more female than male smokers among high school seniorsc.high smoking rates are due to the incease in wealthd.smoking at high school are from low socio-economic backgrounds4/200答案：bdbdb5/200The food we eat seems to have profound effects on our health.Although science has made enormous steps in making food more fit to eat ,it has, at the same time,made many foo ds unfit to eat. Some research has shown that perhaps eighty percent of all human illness es are related to diet and forty percent of cancer is related to the diet as well,especially c ancer of the colon. Different cultures are more likely to cause certain different illnesses b ecause of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additivies,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all th e time to know which things on the packaging labels of processed food are helpful or har mful. The additives which we eat are not all so direct. Farmers often give penicillin to be ef and living animals, and because of this ,penicillin has been found in the milk of treate d cow. Sometimes similar drugs are given to animals not for medical purposes,but for fin ancial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried rep eatedly to control these procedures, the practices continue.1.What is the best possible title of the passage?a.Drug and Foodb.Cancer and Healthc.Food and Healthd.Health and Drug2.Which of the following statements is NOT ture?a.Drugs are always given to animals for medical reasonsb.Some of the additives in our food are added to the food itself and some are given to t he living animalsc.Researchers have known about the potential dangers of food additives for over thirty-five years.d.Food may cause forty percent of cancer in world.3.How has science done something harmful to mankind?a.Because of science , diseases caused by polluted food haven been virtually eliminated.b.It has caused a lack of information concerning the value of food.c.Because of the application of science,some potentially harmful substances have been added to food.d.The scientists have preserved the color of meats,but not of vegetables.4.What are nitrates used for?a.They preserve flavor in packaged foods.b.They preserve the color of meats.c.They are the objects of research.d.They cause the animals to become fatter.5.The word 'carcinogenic' most nearly means '_____'.a.trouble-makingb.color-retainingc.money-makingd.cancer-causing5/200答案：cacbd6/200As the pace of life continues to increase ,we are fast losing the art of relaxation. Once y ou are in the habit of rushing through lift,being on the go from morning till night, it is h ard 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 no t 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 mana gerial 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 differe nce between life or death. The crises we meet today are unlikely to be so extreme,but ho wever little the stress,it involves the same response. It is when such a reaction lasts long,t hrough 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 cann ot remove stress from our lives(it would be unwise to do so even if we could),we need t o 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"6/200答案：dadbcIn the 1960s, many young Americans were dissatisfied with American society. They wante d to end the Vietnam War and to make all of the people in the U.S. epual. Some of the m 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 phil osophy of "do your own thing." A group of artists founded a commune in southern Color ado called "Drop City." Following the ideas of philosopher and architect Buckminster Full er they built domeshaped houses from pieces of old cars. Other groups, such as author K en Kesey's Merry Pranksters, the followers fo San Francisco poet Steve Gakin, and a grou p that called itself the Hog Farm, lived in old school huses and traveled around the Unite d 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, b ut they had to leave when some members of the gruop were arrested for growing marijua na.Not all communes believed in the philosophy of "do you own thing," however . Twin Oa ks , a commune founded in Virgiania in the late 1960s, was based on the ideas of psych ologist B.F.Skinner. The people who lived at Twin Oaks were carefully controlled by Skin ner's "conditioning" techniques to do things that were good for the community. In 1972, It alian 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 believe s 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 people7/200答案：abdcb8/200There 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 l ow 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 individua l 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 demonst rated by the case history of the identical twins, Peter and Mark X. Being identical, the t wins had identical brains at birth, and their growth processes were the same. When the t wins were three months old , their parents died, and they were placed in separate foster h omes. 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 hi s identical brother. Given equal opportunities , the twins , having identical brains,would ha ve 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 childhood8/200答案：bcbcc9/200As she walked round the huge department store,Edith reflected how difficult it was to cho ose a suitable Christmas present for her father.She wish that he was as easy to please as her mother, who was always delighted with perfumeBesides,shoppong at this time of the year was a most disgreeable experience :people trod on your toes,poked you with their elbows and almost knocked you overin their haste to g et to a bargain ahead of you.Partly to have a rest, Edith paused in front of a counter where some attracive ties were o n display. "They are real silk," the assistant assured her, trying to tempt her. "Worth doub le the price." But edit knew from past experience that her choice of ties hardly ever pleas ed 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 pri ces were very reasonable. Edith did not hesitate for long : although her father only smoke d 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 par ents were already at the supper table. Her mother was in an especially cheerful mood, "Y our father has at last to decided to stop smoking." She informed her daughter.1.Edith's father _______.a.did not like presentb.never got presentc.preferred tiesd.was difficult to choose a present for2.The assistant spoke to Edith because she seemed_______.a.attractiveb.interested in tiesc.tiredd.in need of comfort3.Edith stopped at the 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 hurry9/200答案：dbdcd10/200If 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 centur y,if present trends continue, we will have used up all the oil that drives our cars,for exa mple.Even if scientists develop new ways of feeding the human race,the crowded conditio ns on earth will make it necessary for lus to look for open space somewhere else. But n one 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 scient ist, Professor Carl Sagan.Sagan believes that before the earth's resources are compleetely exhausted it will be possi ble to change the atmophere of Venus and so create a new world almost as large as eart h 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 a nd 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 al ge 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 c an 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 pro bably 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 there10/200答案：cabdd11/200What is your favourite colour? Do you like yellow , orange ,red? If you do ,you must be an optimist, a leader, an active person who enjoys life, people and excitement. Do you p refer greys and blues? Then you are probably quiet,shy, and you would rather follow than lead. You tend to be a pessimist. At least, this is what psychologists tell us, and they sh ould know,because they have been seriously studying the meaning of colours preference, a s well as the effect that colours have on human beings. They tells us, among other facts,t hat we do not choose our favourite clour as we grow up----we are born with our preference.If you happen to love brown, you did so, as soon as you opened your eyes, or at leas t as soon as you could see clearly.Colours do influence our moods----there is no doubt about it .A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brin gs warmth and cheer to the saddest winter day. On the other hand ,black is depressing. A black bridge over the Thames River, near London, used to be the scene of more suicides than any other bridge in the area ----until it was repainter green.The number of suicide a ttempts immediately fell sharply ;perhaps it would have fallen even more if the bridge ha d been done in pink or baby blue.Light and bright colours make people not only hppier but more active. It is an established fact that factory workers work better,harder ,and have fewer accidents when their machin es are painted orange rather than black or grey.1."You would rather follow than red" means_______.a.you don't like to follow othersb.you would be a member rather than a leaderc.you would be afraid of following othersd.you would like to be a leader rather than a follower2.If one enjoys life, one is sure to prefer________.a.red to yellowb.blue to orangec.red to greyd.blue to yellow3."They tell us, among other facts,that we don't choose our favourite colours as we grow up." "Among other facts" means______.a.besides other factsb.in regard to other factsc.not considering other factsd.according to other facts4.Which of the following is facts?a.People's preference of one colour to another is instinctb.People's preference of one colour to another is acquired as they grow up.c.More people happen to love brown because they saw something brown when they were bornd.Colours have little influence on our moods5.Those who committed suicide preferred the bridge over the Thames River near london t o others because of _______.a.its shapeb.its structurec.its colourd.its building materials11/200答案：bcaac12/200。

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.

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.

大学英语四级阅读理解训练（一)Classified advertising is that advertising which is grouped in certain secti ons of the paper and is thus distinguished from display advertising。

Suc h groupings as “Help Wanted"，“Real Estate”，“Lost and Found” are made, the rate charged being less than for display advertising. Classified advertisements are a convenience to the reader and a saving to the adverti ser.The reader who is interested in a particular kind of advertisement finds alladvertisements of that type grouped for him. The advertisers may, on this account, use a very small advertisement if it were placed among larger ad vertisements in the paper。

It is evident that the reader approaches the cla ssified advertisement in a different frame of mind from that in which he a pproaches the other advertisements in the paper. He turns to a page of clas sified advertisements to search for the particularadvertisement that will meet his needs. As his attention is voluntary， the advertiser does not need to rely too much extent on display type to get th e reader's attention. Formerly all classified advertisements were of the sa me size and did not have display type。

大学英语四级阅读理解试题及答案（一）There are three kinds of goals: short-term,medium-range and long-term goals.Short-range goals are those that usually deal with current activities,which we can apply on a daily basis.Such goals can be achieved in a week or less,or two weeks,or possible months.It should be remembered that just as a building is no stronger than its foundation ,out long-term goals cannot amount to very munch without the achievement of solid short-term goals.Upon completing our short-term goals,we should date the occasion and then add new short-term goals that will build on those that have been completed.The intermediate goals bukld on the foundation of the short-range goals.They might deal with just one term of school or the entire school year,or they could even extend for several years.Any time you move a step at a time,you should never allow yourself to become discouraged or overwhelmed. As you complete each step,you will enforce the belief in your ability to grow adn succeed.And as your list of completion dates grow,your motivation and desire will increase.Long-range goals may be related to our dreams of the future.

Despit occasional alarms, the country escaped any postwar depression and lived in a state of boom. A n economic survey of the year 1955, a typical year of the 1950’s, may be typical as illustrating the rapid economic growth of the decade. The national output was value at 10 percent above that of 1954 (1955 output was estimated at 392 billion dollars). The production of manufacturers was about 40 percent more than it had averaged in the years immediately following World War 2. The country’s business spent about 30billion dollars for new factories and machinery. National income available for spending was almost a third greater than it had been it had been in 1950. Consumers spent about 256 billion dollars; that is about 700 million dollars a day ,or about twenty-five million dollars every hour , all round the clock. Sixty-five million people held jobs and only a little more than two million wanted jobs but could not find them . Only agriculture complained that it was not sharing in the room. To some observers this was an ominous echo of the mid-1920’s . As farmer’s shre of their products declined , marketing costs rose. But there were , among the observers of the national economy, a few who were not as confident as the majority . Those few seemed to fear that the boom could not last and would eventually lead to the oppsite-depression.1. What is the best title of the passage?a. The Agriculatural Trends of 1950’sb. The Unemployment Rate of 1950’sc. U.S. Economy in the 50’sd. The Federal Budget of 19522. In Line 4 , the word “boom”could best be replaced by______.a. nearby explosionb. thunderous noisec. general public supportd. rapid economic growth3. It can be inferred the national from the passage that most people in the United States in 1955 viewed the national economy with an air of _________.a. confidenceb. confusionc. disappointmentd. suspicion4. Which of the following were LEAST satisfied with the national economy in the 1950’s?a. Economistsb. Frmaersc. Politiciansd. Steelworkers5. The passage states that incom available for spending in the U.S. was greater in 1955 than in 1950 . How much was it ?a. 60%b. 50%c. 33%d. 90%答案：cdabc三Women are also underrepresented in the administration and this is because there are so few women full professors. In 1985,Regent Beryl Milburn produced a report blasting the University of Texas System adminitration for not encouraging women.The University was rated among the lowest for the system.In a 1987 update ,Milburn commended the progress that was made and called for even more improvement.One of the positive results from her study was a System-wide program to inform women of available administrative jobs.College of Communication Associate Dean Patrica Witherspoon,said it is important that woman be flexible when it comesto relocating if they want to rise in the ranks.Although a woman may face a chilly climate on campus , many times in order for her to succeed , she must rise above the problems around her and concentrate on her work.Until women make up a greater percentage of the senior positions in the University and all academia,inequities will exist."Women need to spend their energies and time doing scholarly activities that are important here at the University." Spirduso said. "If they do that will be successful in this system.If they spend their time in little groups mourning the sexual discrimination that they think exists here, they are wasting valuable study time."1.According to Spirduso,women need to ____.a.produce a report on sexual discriminationb.call for further improvement in their working conditionsc.spend their energies and time fighting against sexual discriminationd.spend more time and energy doing scholarly activities2.From this passage ,we know that _____.a.there are many women full professors in the University of Texasb.women play an important part in adminitrating the Universityc.the weather on the campus is chillyd.women make up a small percentage of the senior positions in the University3.Which of the following statements is true?a.the number of women professors in the University in 1987 was greater than that of 1985b.the number of women professors in the University in 1987 was smaller than that of 1985c.the number of women professors was the same as that of 1985d.more and more women professors thought that sexual discrimination did exit in the University4.One of the positive results from Milburn's study was that _____.a.women were told to con centrate on teir workb.women were given information about available administrative jobsc.women were encouraged to take on all the administrative jobs in the Unversityd.women were encouraged to do more scholarly activities5. The title for this passage should be _______.a.The University of Texasburn's Reportc.Women Professorsd.Sexual Discrimination in Academia答案：ddabd四Today ,as in every other day of the year ,more than 3000 U.S. adlescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime,it can be expected that of these 3000 about 23 will be murdered,30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweithts all other factors, whether voluntary or involuntary, as a cause of death.Since the late 1970s, when daily smoking among high school seniors reached 30 precent , smoking rates among youth have declined . While the decline is impressive ,several important issues must be raised.First, in the past several years,smoking rates among youth have declined very little. Second,in the late 1970s ,smoking among male high school seniors exceeded that among female by nearly 10 percent . The statistic is reversing.Third ,several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent .Finally, thouth significant declines in adolescent smoking have occurred in the past decade,no definite reasons for the decline exist. Within this context,the Naional Cancer Instiute (NCI) began its current effort to determine the most effecive measures to reduce smoking levesl among youth.1.According to the author, the deaths among youth are mainly caused by _____.a.traffic accidentsb.smoking-related deseasec.murderd.all of these2.Every day there are over_____high school strdents who will become regular smoker.a.75b.23c.30d.30003.By "dropout" the author means______.a.students who failed the examinationb.students who left schoolc.students who lost their wayd.students who were driven out of school4.The reason for declining adolescent smoking is that ________.a.NCI has taken effective measuresb.smoking is prevented among high school seniorsc.there are many smokers who have died of cancerd.none of these5.What is implied but not stated by the author is that ________.a.smoking rates among youth have declined very littleb.there are now more female than male smokers among high school seniorsc.high smoking rates are due to the incease in wealthd.smoking at high school are from low socio-economic backgrounds答案：bdbdb五The food we eat seems to have profound effects on our health.Although science has made enormous steps in making food more fit to eat ,it has, at the same time,made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additivies,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue.1.What is the best possible title of the passage?a.Drug and Foodb.Cancer and Healthc.Food and Healthd.Health and Drug2.Which of the following statements is NOT ture?a.Drugs are always given to animals for medical reasonsb.Some of the additives in our food are added to the food itself and some are given to the living animalsc.Researchers have known about the potential dangers of food additives for over thirty-five years.d.Food may cause forty percent of cancer in world.3.How has science done something harmful to mankind?a.Because of science , diseases caused by polluted food haven been virtually eliminated.b.It has caused a lack of information concerning the value of food.c.Because of the application of science,some potentially harmful substances have been added to food.d.The scientists have preserved the color of meats,but not of vegetables.4.What are nitrates used for?a.They preserve flavor in packaged foods.b.They preserve the color of meats.c.They are the objects of research.d.They cause the animals to become fatter.5.The word 'carcinogenic' most nearly means '_____'.a.trouble-makingb.color-retainingc.money-makingd.cancer-causing答案：cacbd六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：dadbc七In the 1960s, many young Americans were dissatisfied with American society. They wanted to end the Vietnam War and to make all of the people in the U.S. epual. Some of them decided to "drop out" of American society and form their own societies . They formed utopian communities , which they called "communes," where they could follow their philosophy of "do your own thing."A group of artists founded a commune in southern Colorado called "Drop City." Following the ideas of philosopher and architect Buckminster Fuller they built domeshaped houses from pieces of old cars. Other groups, such as author Ken Kesey's Merry Pranksters, the followers fo San Francisco poet Steve Gakin, and a group that called itself the Hog Farm, lived in old school huses 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：abdcb八There 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：bcbcc九As she walked round the huge department store,Edith reflected how difficult it was to choose a suitable Christmas present for her father.She wish that he was as easy to please as her mother, who was always delighted with perfumeBesides,shoppong at this time of the year was a most disgreeable experience :people trod on your toes,poked you with their elbows and almost knocked you overin their haste to get to a bargain ahead of you.Partly to have a rest, Edith paused in front of a counter where some attracive ties were on display.

I was in the eighth grade at the time, and we were having a final test. During the test, the girl sitting next to me whispered something, but I didn’t understand. So I leaned over her way and found out that she was trying to ask me if I had an extra pen. She showed me that hers was out of ink and would not write. I happened to have an extra one, so I took it out of my pocket and put it on her desk.Later, after the test papers had been turned in, the teacher asked me to stay in the room when all the other students were dismissed（解散）. As soon as we were alone she began to talk to me about what it meant to grow up; she talked about how important it was to stand on your own two feet and be responsible (负责任) for your own acts. For a long time, she talked about honesty and emphasized（强调）the fact that when people do something dishonest, they are really cheating（欺骗）themselves. She made me promise that I would think seriously（认真地）about all the things she had said, and then she told me I could leave. I walked out of the room wondering why she had chosen to talk to me about all those things.Later on, I found out that she thought I had cheated on the test. When she saw me lean over to talk to the girl next to me, it looked as if I was copying answers from the girl’s test paper. I tried to explain about the pen, but all she could say was it seemed very very strange to her that I hadn’t talked of anything about the pen the day she talked to me right after the test. Even if I tried to explain that I was just doing the girl a favor by letting her use my pen, I am sure she continued（继续）to believe that I had cheated on the test.1. The story took place（发生）exactly ____ .A. in the teacher’s officeB. in an exam roomC. in the schoolD. in the language lab2. The girl wanted to borrow a pen, because ____ .A. she had not brought a pen with herB. she had lost her own on her way to schoolC. there was something wrong with her ownD. her own had been taken away by someone3. The teacher saw all this, so she asked the boy ____ .A. to go on writing his paperB. to stop whisperingC. to leave the room immediatelyD. to stay behind after the exam4. The thing(s) emphasized in her talk was(were) ____ .A. honestyB. sense of dutyC. seriousnessD. all of the above5. The boy knew everything ____ .A. the moment he was asked to stay behindB. when the teacher started talking about honestyC. only some time laterD. when he was walking out of the roomB（7minutes）Some kids start to drink alcohol (酒精) at a young age. They think it is part of becoming an adult. They also think drinking is not that bad because so many people do it. They feel it is not as bad as taking drugs (毒品). It is easy for kids to get liquor （酒精饮料）by using fake identification (伪造证件).Parents may start to notice a change in their child’s behavior if the child starts drinking. Kids who drink sometimes stop doing things they normally liked to do. They may keep telephone calls and meetings a secret and not want anybody to touch their things.

大学四级英语仔细阅读专项习题(一)Of the thousands of different kinds of animals that exist in the world man has learned to make friends with an enormous number. Some are pets, and offer him companionship; some give protection, and some do hard work which man cannot do for himself. Dogs, which serve man in all three capacities, are found in various breeds in all countries of the world. The Husky can live in the cold polar regions, and the Saluki is at home in the hottest parts of Central Africa. The inhabitants of certain countries are dependent for their very lives on the camel. In the West Indies the little donkey, strong and sure-footed, carrying heavy loads even in mountainous places, is a familiar sight.来源：考试大Trained and tamed for many generations, domestic animals are not accustomed to roaming(到处走动) in search of food and shelter. They look to their masters to provide for their needs, and as long as these are supplied, they are content to do what their masters require.All domestic animals need proper food. It must be suitable for them, sufficient in quantity, fresh and clean. Some people feed a pet dog or cat on odds and ends of table scraps, and then wonder why the animal seems listless(倦怠的) and dull. The quantity of food depends on the size of the animal and the amount of exercise it takes. Overfeeding is as bad as underfeeding. Containers for food and water must be washed regularly if the animal is to maintain good health.Even well cared for animals may sometimes fall ill. If this happens, the wise master seeks the best advice he can get. All sorts of medicines and treatments are available for sick animals, and in some countries organizations exist to provide them free or at a cheap price. Useful, friendly, hardworking animals deserve to have some time, money and attention spent on their health.1. What main idea does the author want to convey in the first paragraph?A) There exists thousands of species of animals in the world.B) Man came to establish a close relationship with a number of animals.C) In some regions a donkey seems to be a very useful beast.D) An animal will be useless unless domesticated.2.

In their search for precision,scientists have turned to atomic clocks that depend on various vibrating atoms or molecules to supply their "ticking".This is possible because each kind of atom or molecule has its own characteristic rate of vibration.The nitrogen atom in ammonia, for example,vibrates or"ticks"24billion times a seconD.One such atomic clock is so accurate that it will probaly lose no more than a second in3000years.It will be of great improtance in fields such as astronomical is a sesium atom that vibrates9.2billion times a second when heated to the temperature of boiling

大学英语四级阅读题带答案大学英语四级阅读题：【原文】Many private institutions of higher education around the country are in danger.Not all will be saved，andperhaps not all deserve to be saved. There are low-quality schools just as there are low-quality business.We have no obligation to save them simply because they exist.But many thriving institutions that deserve to continue are threatened.They are doing a fine job educationally，but they are caught in a financial squeeze，with no way to reduce rising costs or increase revenuessignificantly.Raising tuition doesnt bring in more revenue，for each time tuition goes up，the enrollment goes down，or the amount that must be given away in student aid goes up.Schools are bad businesses，whether public or private，not usually because of mismanagement but because of the nature of the enterprise.They lose money on every customer，and they can go bankrupt either from too few students or too many students.Even a very good college is a very bad business.It is such colleges，thriving but threatened，I worry about.Low enrollment is not their chief problem.Even with full enrollments，they may go under.Efforts to save them，and preferably to keep them private，are a national necessity.There is no basis for arguing that private schools are inherently (固有地)better than public schools.Examples to the contrary abound.Anyone can name state universities and colleges that rankas the finest in the nation and the world.It is now inevitable that public institutions will be dominant，and therefore diversity is a national necessity.Diversity in the way we support schools tends to give us a healthy diversity in the forms of education.In an imperfect society such as ours，uniformity of education throughout the nation could be dangerous.In an imperfect society，diversity is a positive good. Enthusiastic supporters of public higher education know the importance of sustaining private higher education.大学英语四级阅读题：【题目】Choose correct answers to the question：1.According to the authors opinion，schools are bad businesses because of _______.A.mismanagementB.too few studentsC.financial squeezeD.their characteristics2.The author used the phrase “go under” in Para. 3 to mean “_______”。

大学英语四级阅读习题(一)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 don't like their parentsB) parents don't feel close to their childrenC) parents would not like to live together with their childrenD) independence from one's 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答案1、A2、D3、C4、C5、B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, football’s 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 FIFA’s 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 probablyrefers 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 is 45.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.大学英语四级阅读习题答案21.

(完整版)大学英语四级阅读理解试题及答案-CAL-FENGHAI.-(YICAI)-Company One1As 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 weregood 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 ona.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 your toes,poked you with their elbows and almost knocked you overin their haste to get to a bargain ahead of you.Partly to have a rest, Edith paused in front of a counter where some attracive ties were on display. "They are real silk," the assistant assured her, trying to tempt her. "Worth double the price." But edit knew from past experience that her choice of ties hardly ever pleased her father.She moved on reluctantly and then quite by chance, stopped where a small crowd of man had gathered round a counter. She found some good quality pipes on sale-----and the prices were very reasonable. Edith did not hesitate for long : although her father only smoked a pipe occasionally, she knew that this was a present which was bund to please him.When she got home,with her small well-chosen present concealed in her handbag, her parents were already at the supper table. Her mother was in an especially cheerful mood, "Your father has at last to decided to stop smoking." She informed her daughter.1.Edith's father _______.a.did not like presentb.never got presentc.preferred tiesd.was difficult to choose a present for2.The assistant spoke to Edith because she seemed_______.a.attractiveb.interested in tiesc.tiredd.in need of comfort3.Edith stopped at the next counter_________.a.puroselyb.suddenlyc.unwillinglyd.accidentally4.Edith's father smoked a pipe_______.a.when he was obligedb.on social occasionsc.from time to timed.when he was delighted5.Shopping was very disagreeable at that time of the year because_______.a.coustomers trod on each other's toesb.coustomers poked each other with their elbowsc.customers knocked each otherd.customers were doing their shopping in a great hurry答案：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。

英语四级阅读长篇阅读练习1四级阅读长篇阅读练习1：A University Degree No Longer Confers Financial Securitylions of school-leavers in the rich world are about to bid a tearful goodbye to their parents and start a new life at university. Some are inspired by a pure love of learning. But most also believe that spending three or four years at university--and accumulating huge debts in the process--will boost their chances of landing a well-paid and secure job.B.Their elders have always told them that education is the best way to equip themselves to thrive in a globalised world. Blue-collar workers will see their jobs outsourced and automated, the familiar argument goes. School dropouts will have to cope with a life of cash-strapped (资金紧张的) insecurity. But the graduate elite will have the world at its feet. There is some evidence to support this view. A recent study from Georgetown Universitys Centre on Education and the Workforce argues that"obtaining a post-secondary credential ( 证书) is almost always worth it." Educational qualifications are tightly correlated with earnings: an American with a professional degree can expect to pocket $3.6m over a lifetime; one with merely a high- school diploma can expect only $1.3m. The gap between more- and less-educated earners may be widening. A study in 2002 found that someone with a bachelors degree could expect to earn75% more over a lifetime than someone with only a high-school diploma. Today the disparity is even greater.C.But is the past a reliable guide to the future? Or are we at the beginning of a new phase in the relationship between jobs and education? There are good reasons for thinking that old patterns are about to change--and that the current recession-driven downturn (衰退) in the demand for Western graduates will morph (改变) into something structural. The strong wind of creative destruction that has shaken so manyblue-collar workers over the past few decades is beginning to shake the cognitive elite as well.D.The supply of university graduates is increasing rapidly. The Chronicle of Higher Education calculates that between 1990 and 2007 the number of students going to university increased by 22% in North America, 74% in Europe, 144% in Latin America and 203% in Asia. In 2007 150m people attended university around the world, including 70m in Asia. Emerging economies—specially China--are pouring resources into building universities that can compete with the elite of America and Europe. They are also producing professional- services firms snch as Tata Consulting Services and Infosys that take fresh graduates and turn them into world-class computer programmers and consultants. The best and the brightest of the rich world must increasingly compete with the best and the brightest from poorer countries who are willing to work harder for less money.E. At the same time, the demand for educated labor is being reconfigured (重新配置) by technology, in much the same way that the demand for agricultural labor was reconfigured in the 19th century andthat for factory labor in the 20th. Computers can not only perform repetitive mental tasks much faster than human beings. They can also empower amateurs to do what professionals once did: why hire aflesh-and-blood accountant to complete your tax return when Turbotax (a software package ) will do the job at a fraction of the cost? And the variety of jobs that computers can do is multiplying as programmers teach them to deal with tone and linguistic ambiguity.F.Several economists, including Paul Krugman, have begun to argue that post-industrial societies will be characterized not by a relentless rise in demand for the educated but by a great "hollowing out", as mid-level jobs are destroyed by smart machines and high-level job growth slows. David Autor, of the Massachusetts Institute of Technology (MIT), points out that the main effect of automation in the computer era is not that it destroys blue-collar jobs but that it destroys any job that can be reduced to a routine. Alan Blinder of Princeton University, argues that the jobs graduates have traditionally performed are if anything more "offshorable" than low-wage ones. A plumber or lorry-drivers job cannot be outsourced to India. A computer programmers can.G. A university education is still a prerequisite for entering some of the great industries, such as medicine, law and academia (学术界), that provide secure and well-paying jobs. Over the 20th century these industries did a wonderful job of raising barriers to entry--sometimes for good reasons (nobody wants to be operated on by a barber) and sometimes for self-interested ones. But these industries are beginning to bend the roles. Newspapers are fighting a losing battle with the blogosphere. Universities are replacing tenure-track professors with non-tenured staff. Law firms are contracting out routine work such as"discovery"(digging up documents relevant to a lawsuit) to computerized-search specialists such as Blackstone Discovery. Even doctors are threatened, as patients find advice online and treatment in Walmarts new health centers.H.Thomas Malone of MIT argues that these changes--automation, globalizafion and deregulation--may be part of a bigger change: the application of the division of labor to brain-work. Adam Smiths factory managers broke the production of pins into 18 components. In the same way, companies are increasingly breaking the production of brain-work into ever tinier slices. TopCoder chops up IT projects into bite-sized chunks and then serves them up to a worldwide workforce of freelance coders.I.These changes will undoubtedly improve the productivity ofbrain-workers. They will allow consumers to sidestep (规避 ) the professional industries that have extracted high rents for their services. And they will empower many brain-workers to focus on what they are best at and contract out more tedious tasks to others. But the reconfiguration of brain-work will also make life far less cozy and predictable for the next generation of graduates.46. The creative destruction that has happened to blue-collar workers in the past also starts to affect the cognitive elite.47. For the next generation of graduates, life will be far less comfortable and predictable with brain-work reconfigured.48. After computers are taught by programmers to deal with tone and linguistic ambiguity, the variety of jobs they can do will increase dramatically.49. Most school-leavers believe that, despite the huge debts they owe, going to university will increase their chances of getting secure jobs with high salaries.50. Modern companies are more likely to break the production of intellectual work into ever tinier slices.51. A scholar of Princeton University claims that the jobs traditionally taken by graduates are more likely to be offshored than low-wage ones.52. The income gap between an American professional degree holder and an American high-school graduate shows income is closely related to educational qualifications.53. The changes in the division of brain-work will save consumers some high service fees the professional organizations charge.54. Some students have always been told that. to achieve success ina globalised world, it is most advisable to equip themselves with education.55. Emerging economies are providing a lot of resources to build universities to compete with the elite of America and Europe.【参考译文】大学文凭不再提供铁饭碗A.发达国家的数百万高中毕业生将要含泪告别他们的父母，开始全新的大学生活。

大学英语四级试练习卷一、阅读理解阅读理解（一）There is evidence that the usual variety of high blood pressure is,in part,a familiar disease.Since families have similar genes as well as similar environments,familiar diseases could be due to shared genetic influences,to shared environmental factors,or to both.For some years,the role of one environmental factor commonly shared by families,namely dietary salt(i.e.,sodium chloride),has been studied at Brookhaven National Laboratory.These studies suggest that chromic excess salt ingestion can lead to high blood pressure in man and animals.Some individuals,however,and some rats consume large amounts of salt without developing high blood pressure.No matter how strictly all environmental factors were controlled in these experiments,somesalt-fed animals never developed hypertension whereas a few rapidly developed very severe hypertension followed by early death.These marked variations were interpreted to result from differences in genetic constitution.By mating is successive generations only those animals that failed to develop hypertension from salt ingestion,a resistant strain(the"R" Strain)has been evolved in which consumption of large quantities of saltfails to influence the blood pressure significantly.In contrast,by mating only animals that quickly develop hypertension from salt,a sensitive strain("S"strain)has also been developeD.The availability of these tow strains permits investgations not heretofore possible.They provide a plausible laboratory model on which to investigate some clinical aspects of the human prototypes of hypertension.More important,there might be the possibility of developing methods by which genetic susceptibility of human beings to high blood pressure can be defined without waiting for its appearance.Radioactive sodium22was an important"tool"in working out the characteristics of the sodium chloride metabolism.1.The study of the effects of salt on high blood pressure was carried out______.A.as members of the same family tend to use similar amounts of saltB.to explore the long-term use of a sodium based substanceC.because it was proven that salt caused high blood pressureD.because of the availability of chemically pure salt and its derivatives2.The main difference between"S"and"R"rats is their______.A.need for sodium22B.rate of matingC.reaction to saltD.type of blood3.We can infer from the article that sodium22can de used to______.A.control high blood pressureB.cure high blood pressure caused by saltC.tell the"S"rats from the"R"ratsD.determine what a sodium chloridemetabolism is like4.The most beneficial results of the research might be______.A.development of diets free of saltB.an early cure for high blood pressureC.control of genetic agents that cause high blood pressureD.the early identification of potential high blood pressure victims5.Which of the statements best relates the main idea of this article?A.When salt is added rats and human beings react similarly.B.The near future will see a cure for high blood pressure.C.The medical field is desperately in need of research.D.A tendency toward high blood pressure may be a hereditary factor.阅读理解（二）In the United States,it is not customary to telephone somenone very early in the morning.If you telephone him early in the day,while he is shaving or having breakfast,the time of the call shows that the matter is very important and requires immediate attention.The same meaning is attached to telephone calls made after11:00p.m..If someone receives a call during sleeping hours,he assumes it's a matter of life or death.The time chosen for the call communicates its importance.In social life, time plays a very important part.In the U.S.A.guests tend to feel they are not highly regarded if the invitation to a dinner party is extended only three or four days before the party date.But it is not true in all countries.In other areas of the world,it may be considered foolish to make an appointment too far in advance because plans which are made for a date more than a week away tend to be forgotten.The meaning of thime differs in different parts of the worlD. Thus,misunderstandings arise between peopel from cultures that treat time differently.Promptness is valued highly in American life,for edample.If people are not prompt,they may be regarded as impolite or not fully responsible.In the U.S.no noe would think of keeping a business associate waiting for an hour,it would be too impolite.A person who is5minutes late,he will say a few words of explanation, though perhaps he will not complete the sentence.1."The same meaning is attached to telephone calls made after11:00 p.m.."Here"attached"means______A.takenB.drawnC.givenD.shown2.Supposing one wants to make a telephone call at dawn,this would mean________.A.the matter is importantB.the matter is somewhat importantC.the matter requires immediate attentionD.it is a matter of life and death3.According to this,time plays an important role in_________.A.everyday lifeB.shool lifemunicationsD.private life4.The best title for this is_________.A.the voices of timeB.the importance of timeC.the importance of an ammouncementD.time and tide wait for no man5.According to the,the author of the article may agree to which of the following statements?A.It is appropriate to send your invitation cards three or four days before a dinner party date in U.S.AB.It may be appropriate to send your invitation to your guests three or four days before a dinner party date in some cultures.C.It is best for one to make

大学英语4级真题Passage 1The endless debate about “work-life balance’’ often contains a hopeful footnote about stay-at-home dads. If American society and business won5t make it easier on future female leaders who choose to have children, there is still the ray of hope that increasing numbers of full-time fathers will. But based on today’s socioeconomic trends, this hope is, unfortunately, misguided.It’s true that the number of men who have left work to do their thing as full-time parents has doubled in a decade, but ifs still very small：only 0. 8% of married couples where the stay-at-home father was out of the labor force for a year. Even that percentage is likely inflated by men thrust into their caretaker role by a downsizing. This is simply not a large enough group to reduce the social stigma(污名)and force other adjustments necessary to supporting men in this decision, even if only for a relatively short time.Even shorter times away from work for working fathers are already difficult. A study found that 85% of new fathers take some time off after the birth of a child—but for all but a few, it’s a week or two at most. Meanwhile, the average for women who take leave is more than 10 weeks. Such choices impact who moves up in the organization. While you’re away, someone else is doing your work, making your sales, taking care of your customers. That can’t help you at work. It can only hurt you. Women, of course, face the same issues of returning after a long absence. But with many more women than men choosing to leave the workforce entirely to raise families, returning from an extended parental leave doesn’t raise as many eyebrows as it does for men.Women would make more if they didn't break their earning trajectory (轨迹）by leaving the workforce, or if higher-paying professions were more family-friendly. In the foreseeable future, stay- at-home fathers may make all the difference for individual families, but their presence won’t reduce the numbers of high-potential women who are forced to choose between family and career.56.What gives women a ray of hope to achieve work-life balance?A)More men taking an extended parental leave.B)Peopled changing attitudes towards family.C)More women entering business management.D)The improvement of their socioeconomic status.57.Why does the author say the hope for more full-time fathers is misguided?A)Women are better at taking care of children.B)Many men value work more than their family.C)Their number is too small to make a difference.D)Not many men have the chance to stay at home.58.Why do few men take a long parental leave?A)A long leave will have a negative impact on their career.B)They just have too many responsibilities to fulfill at work.C)The economic loss will be too much for their family to bear.D)They are likely to get fired if absent from work for too long.59.What is the most likely reaction to men returning from an extended parental leave?A) Jealousy. C) Admiration. B) Surprise.D) Sympathy.60.What does the author say about high-potential women in the not-too-distant future?A)They will benefit from the trend of more fathers staying at home.B)They will find high-paying professions a bit more family-friendly.C)They are unlikely to break their career trajectory to raise a family.D)They will still face the difficult choice between career and children.答案：BCABDPassage 2Some of the world’s most significant problems never hit headlines. One example comes from agriculture. Food riots and hunger make news. But the trend lying behind these matters is rarely talked about. This is the decline in the growth in yields of some of the world’s major crops. A new study by the University of Minnesota and McGill University in Montreal looks at where, and how far, this decline is occurring.The authors take a vast number of data points for the four most important crops :rice, wheat, com and soyabeans (大豆).They find that on between 24% and 39% of all harvested areas, the improvement in yields that took place before the 1980s slowed down in the 1990s and 2000s. There are two worrying features of the slowdown. One is that it has been particularly sharp in the world’s most(人口多的）countries, India and China. Their ability to feed themselves has been an important source of relative stability both within the countries and on world food markets. That self-sufficiency cannot be taken for granted if yields continue to slow down or reverse.Second, yield growth has been lower in wheat and rice than in com and soyabeans. This is problematic because wheat and rice are more important as foods, accounting for around half of all calories consumed. Com and soyabeans are more important as feed grains. The authors note that “we have preferentially focused our crop improvement efforts on feeding animals and cars rather than on crops that feed people and are the basis of food security in much of the world. ”, The report qualifies the more optimistic findings of another new paper which suggests that the world will not have to dig up a lot more land for farming in order to feed 9 billion people in 2050, as the Food and Agriculture Organisation has argued.Instead, it says, thanks to slowing population growth, land currently ploughed up for crops might be able to revert (回返）to forest or wilderness. This could happen. The trouble is that the forecast assumes continued improvements in yields, which may not actually happen.61.What does the author try to draw attention to?A) Food riots and hunger in the world.C) The decline of the grain yield growth.B) News headlines in the leading media.D) The food supply in populous countries.62.Why does the author mention India and China in particular?A)Their self-sufficiency is vital to the stability of world food markets.B)Their food yields have begun to decrease sharply in recent years.C)Their big populations are causing worldwide concerns.D)Their food self-sufficiency has been taken for granted.63.What does the new study by the two universities say about recent crop improvement efforts?A)They fail to produce the same remarkable results as before the 1980s.B)They contribute a lot to the improvement of human food production.C)They play a major role in guaranteeing the food security of the world.D)They focus more on the increase of animal feed than human food grains.64.What does the Food and Agriculture Organisation say about world food production in thecoming decades?A)The growing population will greatly increase the pressure on world food supplies.B)The optimistic prediction about food production should be viewed with caution.C)The "slowdown of the growth in yields of major food crops will be reversed.D)The world will be able to feed its population without increasing farmland.65.How does the author view the argument of the Food and Agriculture Organisation?A)It is built on the findings of a new study.B)It is based on a doubtful assumption.C)It is backed by strong evidence.D)It is open to further discussion.答案：CADDBPassage 3Junk food is everywhere. We’re eating way too much of it. Most of us know what we’re doing and yet we do it anyway.So here’s a suggestion offered by two researchers at the Rand Corporation : Why not take a lesson from alcohol control policies and apply them to where food is sold and how it’s displayed?“Many policy measures to control obesity(肥胖症）assume that people consciously and rationally choose what and how much they eat and therefore focus on providing information and more access to healthier foods,” note the two researchers.“In contrast,” the researchers continue, “ many regulations that don’t assume people make rational choices have been successfully applied to control alcohol, a substance—like food—of which immoderate consumption leads to serious health problems. ’’The research references studies of peopled behavior with food and alcohol and results of alcohol restrictions, and then lists five regulations that the researchers think might be promising if applied to junk foods. Among them:Density restrictions：licenses to sell alcohol aren’t handed out unplanned to all comers but are allotted (分配) based on the number of places in an area that already sell alcohol. These make alcohol less easy to get and reduce the number of psychological cues to drink.Similarly, the researchers say, being presented with junk food stimulates our desire to eat it. So why not limit the density of food outlets, particularly ones that sell food rich in empty calories? And why not limit sale of food in places that aren5t primarily food stores?Display and sales restrictions: California has a rule prohibiting alcohol displays near the cash registers in gas stations, and in most places you can’t buy alcohol at drive-through facilities. At supermarkets, food companies pay to have their wares in places where they’re easily seen. One could remove junk food to the back of the store and ban them from the shelves at checkout lines. The other measures include restricting portion sizes, taxing and prohibiting special price deals for junk foods, and placing warning labels on the products.56.What does the author say about junk food?A)People should be educated not to eat too much.B)It is widely consumed despite its ill reputation.C)Its temptation is too strong for people to resist.D)It causes more harm than is generally realized.57.What do the Rand researchers think of many of the policy measures to control obesity?A) They should be implemented effectively.C) They are based on wrong assumptions.B) They provide misleading information.D) They help people make rational choices.58.Why do policymakers of alcohol control place density restrictions?A)Few people are able to resist alcohol’s temptations.B)There are already too many stores selling alcohol.C)Drinking strong alcohol can cause social problems.D)Easy access leads to customers’ over-consumption.59.What is the purpose of California’s rule about alcohol display in gas stations?A)To effectively limit the density of alcohol outlets.B)To help drivers to give up the habit of drinking.C)To prevent possible traffic jams in nearby areas.D)To get alcohol out of drivers’ immediate sight.60.What is the general guideline the Rand researchers suggest about junk food control?A)Guiding people to make rational choices about food.B)Enhancing people’s awareness of their own health.C)Borrowing ideas from alcohol control measures.D)Resorting to economic, legal and psychological means.答案：CCDDCPassage 4Kodak’s decision to file for bankruptcy (破产）protection is a sad, though not unexpected, turning point for a leading American corporation that pioneered consumer photography and dominated the film market for decades, but ultimately failed to adapt to the digital revolution.Although many attribute Kodak’s downfall to “complacency ( 自满)”that explanation doesn’t acknowledge the lengths to which the company went to reinvent itself. Decades ago, Kodak anticipated that digital photography would overtake film—and in fact, Kodak invented the first digital camera in 1975—but in a fateful decision, the company chose to shelf its new discovery to focus on its traditional film business.It wasn’t that Kodak was blind to the future, said Rebecca Henderson, a professor at Harvard Business School, but rather that it failed to execute on a strategy to confront it. By the time the company realized its mistake, it was too late.Kodak is an example of a firm that was very much aware that they had to adapt, and spent a lot of money trying to do so, but ultimately failed. Large companies have a difficult time switching to new markets because there is a temptation to put existing assets into the new businesses.Although Kodak anticipated the inevitable rise of digital photography, its corporate(企业的）culture was too rooted in the successes of the past for it to make the clean break necessary to fully embrace the future. They were a company stuck in time. Their history was so important to them. Now their history has become a liability.Kodak’s downfall over the last several decades was dramatic. In 1976, the company commanded 90% of the market for photographic film and 85% of the market for cameras. But the 1980s brought new competition from Japanese film company Fuji Photo, which undermined Kodak by offering lower prices for film and photo supplies. Kodak’s decision not to pursue the role of official film for the 1984 Los Angeles Olympics was a major miscalculation. The bid went instead to Fuji, which exploited its sponsorship to win a permanent foothold in the marketplace.61.What do we learn about Kodak?A)It went bankrupt all of a sudden.B)It is approaching its downfall.C)It initiated the digital revolution in the film industry.D)It is playing the dominant role in the film market.62.Why does the author mention Kodak’s invention of the first digital camera?A)To show its early attempt to reinvent itself.B)To show its effort to overcome complacency.C)To show its quick adaptation to the digital revolution.D)To show its will to compete with Japan’s Fuji Photo.63.Why do large companies have difficulty switching to new markets?A)They find it costly to give up their existing assets.B)They tend to be slow in confronting new challenges.C)They are unwilling to invest in new technology.D)They are deeply stuck in their glorious past.64.What does the author say Kodak’s history has become?A) A burden.B) A mirror.C) A joke.D) A challenge.65.What was Kodak’s fatal mistake?A) Its blind faith in traditional photography.C) Its refusal to sponsor the 1984 Olympics.B) Its failure to see Fuji Photo’s emergence.D) Its overconfidence in its corporate culture.答案：BADACPassage 5When it’s five o’clock, people leave their office. The length of the workday, for many workers, is defined by time. They leave when the clock tells them they’re done.These days, the time is everywhere: not just on clocks or watches, but on cell-phones and computers. That may be a bad thing, particularly at work. New research shows that clock-based work schedules hinder morale (士气) and creativity.Clock-timers organize their day by blocks of minutes and hours. For example：a meeting from 9 a. m. to 10 a. m. , research from 10 a. m. to noon, etc. On the other hand, task-timers have a list of things they want to accomplish. They work down the list, each task starts when the previous task is completed. It is said that all of us employ a mix of both these types of planning.What, then, are the effects of thinking about time in these different ways? Does one make us more productive? Better at the tasks at hand? Happier? In experiments conducted by Tamar Avnet and Anne-Laure Sellier, they had participants organize different activities—from project planning, holiday shopping, to yoga —by time or to-do list to measure how they performed under “clock time vs “task time.” They found clock timers to be more efficient but less happy because they felt little control over their lives. Task timers are happier and more creative, but less productive. They tend to enjoy the moment when something good is happening, and seize opportunities that come up.The researchers argue that task-based organizing tends to be undervalued and under-supported in business culture. Smart companies, they believe, will try to bake more task-based planning into their strategies.This might be a small change to the way we view work and the office, but the researchersargue that it challenges a widespread characteristic of the economy: work organized by dock time. While most people will still probably need, and be, to some extent, clock-timers, task-based timing should be used when perfoming a job that requires more creativity. It’ll make those tasks easier, arid the task- doers will be happier.56.What does the author think of time displayed everywhere?A)It makes everybody time-conscious.B)It is a convenience for work and life.C)It may have a negative effect on creative work.D)It clearly indicates the fast pace of modem life.57.How do people usually go about their work according to the author?A)They combine clock-based and task-based planning.B)They give priority to the most urgent task on hand.C)They set a time limit for each specific task.D)They accomplish their tasks one by one.58.What did Tamar Avnet and Anne-Laure Sellier find in their experiments about clocks timers?A) They seize opportunities as they come up.C) They have more control over their lives.B) They always get their work done in time.D) They tend to be more productive.59.What do the researchers say about today’s business culture?A)It does not support the strategies adopted by smart companies.B)It does not attach enough importance to task-based practice.C)It places more emphasis on work efficiency than on workers5 lives.D)It aims to bring employees, potential and creativity into full play.60.What do the researchers suggest?A)Task-based timing is preferred for doing creative work. B)It is important to keep a balance between work and life.C)Performing creative jobs tends to make workers happier. D)A scientific standard should be adopted in job evaluation.答案：CADAAPassage 6Martha Stewart was charged, tried and competed of a crime in 2004. As she neared the end of her prison sentence, a well-known columnist wrote that she was “ paying her dues,” and that “ there is simply no reason for anyone to attempt to deny her right to start anew.”Surely, the American ideal of second chances should not be reserved only for the rich and powerful. Unfortunately, many federal and state laws impose post-conviction restrictions on a shockingly large number of Americans, who are prevented from ever fully paying their debt to society.At least 65 million people in the United States have a criminal record. This can result in severe penalties that continue long after punishment is completed.Many of these penalties are imposed regardless of the seriousness of the offense or the person’s individual circumstances. Laws can restrict or ban voting, access to public housing, and professional and business licensing. They can affect a person’s ability to get a job and qualification for benefits.In all, more than 45, 000 laws and rules serve to exclude vast numbers of people from fullyparticipating in American life.Some laws make sense. No one advocates letting someone convicted of pedophilia（恋童癖）work in a school. But too often collateral(附随的）consequences bear no relation to public safety. Should a woman who possessed a small amount of drugs years ago be permanently unable to be licensed as a nurse?These laws are also counterproductive, since they make it harder for people with criminal records to find housing or land a job, two key factors that reduce backsliding.A recent report makes several recommendations, including the abolition of most post-conviction penalties, except for those specifically needed to protect public safety. Where the penalties are not a must, they should be imposed only if the facts of a case support it.The point is not to excuse or forget the crime. Rather, it is to recognize that in America’s vast criminal justice system, second chances are crucial. It is in no one’s interest to keep a large segment of the population on the margins of society.61.What does the well-known columnist’s remark about Martha Stewart suggest?A)Her past record might stand in her way to a new life.B)Her business went bankrupt while she was in prison.C)Her release from prison has drawn little attention.D)Her prison sentence might have been extended.62.What do we learn from the second paragraph about many criminals in America?A)They backslide after serving their terms in prison.B)They are deprived of chances to turn over a new leaf.C)They receive severe penalties for committing minor offenses.D)They are convicted regardless of their individual circumstances.63.What are the consequences for many Americans with a criminal record?A) They remain poor for the rest of their lives.C) They are marginalized in society.B) They are deprived of all social benefits.D) They are deserted by their family.64.What does the author think of the post-conviction laws and rules?A)They help to maintain social stability.B)Some of them have long been outdated.C)They are hardly understood by the public.D)A lot of them have negative effects on society.65.What is the author’s main purpose in writing the passage?A)To create opportunities for criminals to reform themselves.B)To appeal for changes in America’s criminal justice system.C)To ensure that people with a criminal record live a decent life.D)To call people’s attention to prisoners’ conditions in America.答案：ABCDBPassage 7The wallet is heading for extinction. As a day-to-day essential，it will die off with the generation who read print newspapers. The kind of shopping—where you hand over notes and count out change in return—now happens only in the most minor of our retail encounters, like buying a bar of chocolate or a pint of milk from a comer shop. At the shops where you spend any real money, that money is increasingly abstracted. And this is more and more true, the higher upthe scale you go. At the most cutting-edge retail stores—Victoria Beckham on Dover Street, for instance—you don’t go and stand at any kind of cash register when you decide to pay. The staff are equipped with iPads to take your payment while you relax on a sofa.Which is nothing more or less than excellent service, if you have the money. But across society, the abstraction of the idea of cash makes me uneasy. Maybe I’m just old-fashioned. But earning money isn’t quick or easy for most of us. Isn’t it a bit weird that spending it should happen in half a blink (眨眼）of an eye? Doesn’t a wallet—that time-honoured Friday-night feeling of pleasing, promising fatness—represent something that matters?But I’ll leave the economics to the experts. What bothers me about the death of the wallet is the change it represents in our physical environment. Everything about the look and feel of a wallet—the way the fastenings and materials wear and tear and loosen with age, the plastic and paper and gold and silver, and handwritten phone numbers and printed cinema tickets—is the very opposite of what our world is becoming. The opposite of a wallet is a smartphone or an iPad. The rounded edges, cool glass，smooth and unknowable as a pebble (鹅卵石）. Instead of digging through pieces of paper and peering into comers, we move our fingers left and right. No more counting out coins. Show your wallet, if you still have one. It may not be here much longer.56.What is happening to the wallet?A) It is disappearing.C) It is becoming costly,B) It is being fattened.D) It is changing in style.57.How are business transactions done in big modem stores?A)Individually.C) In the abstract.B)Electronically.D) Via a cash register.58.What makes the author feel uncomfortable nowadays?A)Saving money is becoming a thing of the past.B)The pleasing Friday-night feeling is fading.C)Earning money is getting more difficult.D)Spending money is so fast and easy.59.Why does the author choose to write about what’s happening to the wallet?A)It represents a change in the modem world.B)It has something to do with everybody’s life.C)It marks the end of a time-honoured tradition.D)It is the concern of contemporary economists.60.What can we infer from the passage about the author?A)He is resistant to social changes.B)He is against technological progress.C)He feels reluctant to part with the traditional wallet.D)He feels insecure in the ever-changing modem world.答案：ABDADPassage 8Everybody sleeps, but what people stay up late to catch—or wake up early in order not to miss— varies by culture.From data collected, it seems the things that cause us to lose the most sleep, on average, are sporting events, time changes, and holidays.Around the world, people changed sleep patterns thanks to the start or end of daylight savings time, Russians, for example, began to wake up about a half-hour later each day after President Vladimir Putin shifted the country permanently to “winter time” starting on October 26.Russia’s other late nights and early mornings generally correspond to public holidays. On New Year’s Eve, Russians have the world’s latest bedtime，hitting the hay at around 3:30 a.m.、Russians also get up an hour later on International Women’s Day, the day for treating and celebrating female relatives.Similarly, Americans, late nights, late mornings, and longest sleeps fall on three-day weekends. Canada got the least sleep of the year the night it beat Sweden in the Olympic hockey （冰球）. The World Cup is also chiefly responsible for sleep deprivation(剥夺）.The worst night for sleep in the U. K was the night of the England-Italy match on June 14. Brits stayed up a half-hour later to watch it, and then they woke up earlier than usual the next morning thanks to summer nights, the phenomenon in which the sun barely sets in northern countries in the summertime. That was nothing, though, compared to Germans, Italians, and the French, who stayed up around an hour and a half later on various days throughout the summer to watch the Cup.It should be made clear that not everyone has a device to record their sleep patterns; in some of these nations, it’s likely that only the richest people do. And people who elect to track their sleep may try to get more sleep than the average person. Even if that’s the case, though, the above findings are still striking. If the most health-conscious among us have such deep swings in our shut-eye levels throughout the year, how much sleep are the rest of us losing?61.What does the author say about peopled sleeping habits?A) They are culture-related.C) They change with the seasons.B) They affect peopled health.D) They vary from person to person.62.What do we learn about the Russians regarding sleep?A)They don’t fall asleep until very late.C)They get less sleep on public holidays.B)They don’t sleep much on weekends.D)They sleep longer than people elsewhere.63.What is the major cause for Europeans’ loss of sleep?A)The daylight savings time.C)The World Cup.B)The colorful night life.D)The summertime.64.What is the most probable reason for some rich people to use a device to record their sleep patterns?A) They have trouble falling asleep.C) They are involved in a sleep research.B) They want to get sufficient sleep.D) They want to go to bed on regular hours.65.What does .the author imply in the last paragraph?A)Sleeplessness does harm to peopled health.B)Few people really know the importance of sleep.C)It is important to study our sleep patterns.D)Average people probably sleep less than the rich.答案：ACCBBPassage 9Could you reproduce Silicon Valley elsewhere, or is there something unique about it?It wouldn't be surprising if it were hard to reproduce in other countries, because you couldn't reproduce it in most of the US either. What does it take to make a Silicon Valley?It's the right people. If you could get the right ten thousand people to move from Silicon Valley to Buffalo, Buffalo would become Silicon Valley.You only need two kinds of people to create a technology hub (中心) : rich people and nerds (痴迷科研的人).Observation bears this out. Within the US, towns have become star, up hubs if and only if they have both rich people and nerds. Few startups happen in Miami, for example, because although it's full of rich people, it has few nerds. It's not the kind of place nerds like.Whereas Pittsburgh has the opposite problem: plenty of nerds, but no rich people.The top US Computer Science departments are said to be MIT, Stanford, Berkeley, and Carnegie-Mellon. MIT yielded Route 128.Stanford and Berkeley yielded Silicon Valley. But what did Carnegie-Mellon yield in Pittsburgh? And what happened in Ithaca, home of Cornell University, which is also high on the list?I grew up in Pittsburgh and went to college at Cornell, so I can answer for both. The weather is terrible, particularly in winter, and there's no interesting old city to make up for it, as there is in Boston. Rich people don't want to live in Pittsburgh or Ithaca. So while there're plenty of hackers (电脑迷) who could start startups, there's no one to invest in themDo you really need the rich people? Wouldn't it work to have the government invest in the nerds?No, it would not. Start up investors are a distinct type of rich people. They tend to have a lot of experience themselves in the technology business. This helps them pick the right startups, and means they can supply advice and connections as well as money. And the fact that they have a personal stake in the outcome makes them really pay attention.56.What do we learn about Silicon Valley from the passage?A. Its success is hard to copy anywhere else.B. It is the biggest technology hub in the US.C. Its fame in high technology is incomparable.D. It leads the world in information technology.57.What makes Miami unfit to produce a Silicon Valley?A. Lack of incentive for investment.B. Lack of the right kind of talents.C. Lack of government support.D. Lack of famous universities.58.In what way is Carnegie-Mellon different from Stanford, Berkeley and MIT?A. Its location is not as attractive to rich people.B. Its science departments are not nearly as good.C. It does not produce computer hackers and nerds.D. It does not pay much attention to business startups.59.What does the author imply about Boston?A. It has pleasant weather all year round.。

大学四级英语考试阅读习题(一)The motor vehicle has killed and disabled more people in its brief history than any bomb or weapon ever invented. Much of the blood on the street flows essentially from uncivil behavior of drivers who refuse to respect the legal and moral rights of others. So the massacre on the road may be regarded as a social problem.In fact, the enemies of society on wheels are rather harmless people or ordinary people acting carelessly, you might say. But it is a principle both of law and common morality that carelessness is no excuse when ones actions could bring death or damage to others.A minority of the killers go even beyond carelessness to total negligence.Researchers have estimated that as many as 80 per cent of allautomobile accidents can be attributed to the psychological condition of the driver. Emotional upsets can distort drivers reactions, slow their judgment, and blind them to dangers that might otherwise be evident. The experts warn that it is vital for every driver to make a conscious effort to keep ones emotions under control.Yet the irresponsibility that accounts for much of the problem is not confined to drivers. Street walkers regularly violate traffic regulations; they are at fault in most vehicle walker accidents. And many cyclists even believe that they are not subject to the basic rules of the road.Significant legal advances have been made towards safer driving in the past few years. Safety standards for vehicle have been raised both at the point of manufacture and through periodicroad-worthiness inspections. In addition, speed limits have been lowered. Due to these measures, the accident rate has decreased. But the accident experts still worry because there has been little or no improvement in the way drivers behave. The only real and lasting solution, say the experts, is to convince people that driving is a skilled task requiring constant care and concentration. Those who fail to do all these things pose a threat to those with whom they share the road.62. The word "massacre" in line 3 paragraph one means _____A) mass-killing.B) disaster.C) tragedy.D) accident.63. What is the authors main purpose in writing the passage?A) To show that the motor vehicle is a very dangerous invention.B) To promote understanding between careless drivers and street walkers.C) To discuss traffic problems and propose possible solutions.D) To warn drivers of the importance of safe driving.64. According to the passage, traffic accidents may be regarded as a social problem because _____.A) autos have become most destructive to mankindB) people usually pay little attention to law and moralityC) civilization brings much harm to peopleD) the lack of virtue is becoming more severe65. Why does the author mention the psychological condition of the driver in Paragraph Three?A) To give an example of the various reasons for road accidents.B) To show how important it is for drivers to be emotionally healthy.C) To show some of the inaccurate estimations by researchers.D) To illustrate the hidden tensions in the course of driving.66. Who are NOT mentioned as being responsible for the road accidents?A) Careless bicycle-riders.B) Mindless people walking in the street.C) Irresponsible drivers.D) Irresponsible manufactures of automobiles.大学四级英语考试阅读习题答案ACBBD大学四级英语考试阅读习题(二)Merchant and passenger ships are generally required to have a life preserver for every person aboard and in many cases, a certain percentage of smaller sizes for children. According to United States requirements, life preservers must design, reversible capable of being quickly adjusted to fit the uninitiated individual, and must be so designed as to support the wearer in the water in an upright or slightly backward position.Sufficient buoyancy(浮力) to support the wearer should be retained by the life preserver after 48 hours in the water, and it should be reliable even after long period of storage. Thus it should be made of materials resistant to sunlight, gasoline, and oils, andit should be not easily set on fire.?The position in which the life preserver will support a person who jumps or falls into the water is most important, as is its tendency to turn the wearer in the water from a face-down position to an upright or slightly backward position, with his face clear of the water, even when the wearer is exhausted or unconscious.The method of adjustment to the body should be simple, andself-evident to uninitiated persons even in the dark under the confused conditions, which follow a disaster. Thus, the life be reversible that it is nearly impossible to get it on wrong. Catches, straps, and ties should be kept to a minimum. In addition, the life preserver must be adjustable to the wide variety of shapes and sizes of wearers, since this greatly affects the position of floating and the self-righting qualities. A suitable life also be comfortable to wear at all times, in and out of the water, not so heavy as to encourage to take it off on shipboard while the ship is in danger, nor so burdensome that it hinders a person in the water while trying to swim.1. The passage is mainly about____.A) the uses of life preserversB) the design of life preserversC) the materials for life preserversD) the buoyancy of life preservers2. According to the passage, a life be first of all ____.A) adjustable B) comfortable C) self-evident D) self-righting3. United States Coast Guard does NOT require the life preserver to be made ____.A) with as few strings as possibleB) capable of being worn on both sidesC) according to each wearers sizeD) comfortable and light to wear4. By "the uninitiated individual" (Para. 1, Line. 4) the author refers to the person ____.A) who has not been instructed how to use a life preserverB) who has a little experience in using a life preserverC) who uses a life preserver without permissionD) who becomes nervous before a disaster5. What would happen if a person were supported by the life preserver in a wrong position?A) The waves would move him backwards.B) The water would choke him.C) He would immediately sink to the bottom.D) He would be exhausted or unconscious.大学四级英语考试阅读习题答案1.

大学四级考试英语阅读习题(一)The food we eat seems to have profound effects on ourhealth.Although science has made enormous steps in making food more fit to eat ,it has, at the same time,made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additivies,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because ofthis ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons. The farmers are simply trying to fatten the animalsin order to obtain a higher price on the market.

大学生英语四级考试阅读理解试题及答案解析1The world has become a world of cities. With the present rate of urban growth(3. 8% in the Third World) , the majority of the population of the world will be living in cities by the year 2000. This will transform the rural-urban equation which has marked the history of mankind up to now and will call for new example and a great deal of innovation to face this phenomenon.This being so, one must accept the fact that for some years to come, no policy will be capable of stopping or reversing the present migratory trend from the rural areas to the cities in the Third World. In Africa, the urban population will reach 330 million people by the end of the century as against 150 million in 1995.The number of people living in shanty-towns (贫富窟) will inevitably increase in spite of the efforts to improve housing conditions.Africa alone needs to build 12 million housing units between now and the year 2000 to meet its most basic needs. In an ILO study, M. S. V. Sethuraman estimates that in 70 Third "World cities the proportion of people living in shanty-towns varies from 15% to 70% and that about US $ 116 billion is required to give minimum comfort to these people by the turn of the century—less than US $ 10 billion per year.The world population is growing at a rate of about 90 million people per year, with the Third World accounting for 80 million of them. The pressure on cities can only go on increasing. The urban population of the developing countries will exceed 2 billion people by the year 2000 and since the main reason for the high demographic (人口统计的) growth is poverty, the additional population will be mostly made of people of very limited means.21. If the urban population of the developing countries exceeds 2 billion people by the year 2000, the main problem the additional people will face is______.A. housingB. foodC. povertyD. limited land22. According to the passage, "about US $116 billion is required to give minimum comfort to these people by the turn of the century—less than US $ 10 billion per year. " Do you think which year was the article written by saying "less than $ 10 billion per year" by theturn of the century?A. 1985.B. 1990.C. 1988.D. 2000.23. The mankind should face the phenomenon that the world has become a world of cities with______.A. a lot of difficultiesB. efforts to improve housing conditionC. pressure of the basic needsD. new models and a great deal of transformation of ideas and methods24. In Africa, people in cities will be______by the end of the century.A. almost twice as much as in 1985B. doubled than that in 1985C. over twice as much as in 1985D. 300 million25. In spite of the efforts to improve housing condition, the number of people living in shanty-towns will increase because______.A. houses in shanty-towns are cheapB. shanty-towns could provide people with minimum comfortC. no policy will be capable of stopping or changing the present immigrant tendency from the rural areas to the cities in the Third WorldD. the Third Word population is growing at a rate of about 80 million people per year答案：21. C 22. C 23. D 24. C 25. C大学生英语四级考试阅读理解试题及答案解析2There are two factors which determine an individuals intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual—the sort of environment in which he is reared. If an individual is handicapped envionmentally ,it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable. The importance of environment in determining an individuals intellingence can be demonstrated by the case history of the identical twins, Peter and Mark X. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old , their parents died, and they were placed in separate foster homes. Peter was reated by parents of low intelligence in an isolatedcommunity with poor educational pooprtunities.Mark was reared inthe home of well-to-do parents who had been to college. He was read to as a child , sent to good schools, and given every opportunity to be stimulated intellectually.This enviromental difference continued until the twins were in their late teens, when theywere giben tesets to measure their intelligence. Marks I.Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities , the twins , having identical brains,would have tested at roughly the same level.1.This selection can best be titled_________.a.Measuring Your Intelligenceb.Intelligence and Environmentc.The Case of Peter and Markd.How the brain Influences Intelligence2.The beststatement of the main idea of this passage is that _____. a.human brains differ considerablyb.the brain a person is born with is improtant in determining his intelligencec.environment is crucial in determining a persons intelligenced. persons having identical brains will have roughly the same intelligence3.According to the passage , the average I.Q.is _____.a.85b.100c.110d.1254.The case history of the twins appears to support the conclusion that _______. a.individual with identical brains seldom test at same level b.an individuals intelligence is determined only by his enviroment ck of opportunity blocks the growth of intelligence d.changes of enviromentproduce changes in the structure of the brain5.This passage suggests that an individual s I.Q.______. a.can be predicted at birthb.stays the same throuthout his lifec.can be increased by educationd.is determined by his childhood答案：bcbcc大学生英语四级考试阅读理解试题及答案解析3There are three kinds of goals: short-term,medium-range and long-term goals. Short-range goals are those that usually deal with current activities,which we can apply on a daily basis.Such goals can be achieved in a week or less,or two weeks,or possible months.It should be remembered that just as a building is no stronger than its foundation ,out long-term goals cannot amount to very munch without the achievement of solid short-term goals.Upon completing our short-term goals,we should date the occasion and then add new short-term goals that will build on those that have been completed. The intermediate goals bukld on the foundation of the short-range goals.They might deal with just one term of school or the entire school year,or they could even extend for several years.Any time you move a step at a time,you should never allow yourself to become discouraged or overwhelmed. As you complete each step,you will enforce the belief inyour ability to grow adn succeed.And as your list of completion dates grow,your motivation and desire will increase. Long-range goals may be related to our dreams of the future. They might cover five years or more. Life is not a static thing.We should never allow a long-term goal to limit us or our course of action. 1.Our long-term goals mean a lot______.A.if we complete our short-range goalsB.if we cannot reach solid short-term goalsC.if we write down the datesD.if we put forward some plans2.New short-term goals are bulid upon______.A.two yearsB.long-term goalsC.current activitiesD.the goals that have been completed3.When we complete each step of our goals ,______.A.we will win final successB.we are overwhelmedC.we should build up confidence of successD.we should strong desire for setting new goals 4.Once our goals are drawn up,_______.A.we should stick to them until we complete themB.we may change our goals as we have new ideas and opportunitiesC.we had better wait for the exciting news of successD.we have made great decision5.It is implied but not stated in the passage that ______.A.those who habe long-term goals will succeedB.writing down the dates may discourage youC.the goal is only a guide for us to reach our desinationD.every should have a goal答案：adcbc大学生英语四级考试阅读理解试题及答案解析4Today ,as in every other day of the year ,more than 3000 U.S. adlescents will smoke their first cigarette on their way to becoming regular smokers as adults.
