大学英语四级阅读理解练习题附答案Flying over a desert area in an airplane, two scientists looked down with trained eyes at trees and bushes. After an hour's 11 one of the scientists wrote in his book, "Look here for 12 metal. " Scientists in another airplane, flying over a mountain region, sent a 13 to other scientists on the ground, "Gold possible. " Walking across hilly ground, four scientists reported, "This ground should be searched for metals. " From an airplane over a hilly wasteland a scientist sent back by radio one word, "Uranium. "None of the scientists had X-ray eyes: they had no 14 powers for looking down below the earth's surface. They were 15 putting to use one of the newest methods of 16 minerals in the ground—using trees and plants as 17 thatcertain minerals may lie beneath the ground on which the trees and plants are growing.This newest method of searching for minerals is 18 on the fact that minerals deep in the earth may 19 the kind of bushes and trees that grow on the surface.At Watson Bar Creek, a brook six thousand feet high in the mountains of British Columbia, Canada, a mineral search group gathered bags of tree seeds. Boxes were filled with small branches from the trees. Roots were dug and put into boxes. Each bag and box was 20 marked. In a scientific laboratory the parts of the forest trees were burned to ashes and tested. Each small part was examined to learn whether there were minerals in it.A. signsB. sufficientlyC. locatingD. affectE. merelyF. magicG. hintsH. carefullyI. findingJ. messageK. flightL. probableM. revealingN. basedO. information答案:11. K 12. L 13. J 14. F 15. E 16. C 17. A 18. N 19. D 20. HThere are two factors which determine an individual's intelligence. Thefirst is the sort of brain he is born with. Human brains differ considerably , some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual— the sort of environment in which he is brought up. If anindividual is handicapped不利 environmentally, it is likely that his brainwill fail to develop and he will never attain the level of intelligence of which he is capable.The importance of environment in determining an individual's intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster抚养 homes. Peter was raised by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well-to-do parents who had beento college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark's I. Q. was 125, twenty-five points higherthan the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.21. This selection can best be titled____________.A. Measuring Your IntelligenceB. Intelligence and EnvironmentC. The Case of Peter and MarkD. How the Brain Influences Intelligence22. The best statement of the main idea of this passage is that _______.A. human brains differ considerablyB. the brain a person is born with is important in determining his intelligenceC. environment is crucial in determining a person's intelligenceD. persons having identical brains will have roughly the same intelligence23. According to the passage, the average I. Q. is_______.A. 85 .B. 100C. 110D. 12524. The case history of the twins appears to support the conclusionthat_______.A. individuals with identical brains seldom test at the same levelB. an individual's intelligence is determined only by his environmentC. lack of opportunity blocks the growth of intelligenceD. changes of environment produce changes in the structure of the brain25. This passage suggests that an individual's I. Q. _______.A. can be predicted at birthB. stays the same throughout his lifeC. can be increased by educationD. is determined by his childhood答案:21. B 22. C 23. B 24. C 25. C 感谢您的阅读,祝您生活愉快。

英语四级阅读理解练习题(一)Not all sounds made by animals serve as language, and we have only to turn to thatextraordinary discovery of echolocation (回声定位) in bats to see a case in which the voice playsa strictly practical role.To get a full appreciation of what this means we must turn first to some recent humaninventions. Everyoneknows that if he shouts near a wall or a mountainside, an echo will comeback. The further off this solid obstacle, the longer time it will take for the return of the echo.A sound made by tapping on the main body of a ship will be reflected from the sea bottom, andby measuring the time interval between the taps andthe receipt ofthe echoes the depth ofthe sea at that point can be calculated. So was born the echo-sounding equipment, now ingeneral use in ships. Every solid object will reflect a sound, varying according to the size andnature of the object. A shoal of fish will do this. So it is a comparatively simple stepfromlocating the sea bottom to locating a shoal of fish. With experience, and with improvedequipment, it is now possible not only to locate fish but to tell if it is herring, cod, orotherwell-known fish, by the pattern of its echo.A few years ago it was found that certain bats emit squeaks (吱吱声) and by receiving heechoes they could locate and steer clear of obstacles--or locate flying insects on which theyfeed. This echolocation in bats is often compared with radar, the principle of which is similar.练习题:Choose correct answers to the question:1.The main purpose of this passage is to ______.A. describe that animals can make different soundsB. prove that animals voices can play practical rolesC. inspire the readers to make more inventionsD. startle the readers with some shocking facts2. The discovery of echolocation may help with all of thefollowing EXCEPTA. measuring the depth of the seaB. distinguishing different kinds of fishC. improving the functions of radarD. varying the size and nature of an object3. By saying "A shoal of fish will do this"(Lines 6-7, Para.2), the author means________.A. only one special kind of fish can reflect soundsB. only one special kind of fish can be used to help locate a shipC. a large group of fish can reflect soundsD. a large group of fish can be used to help locate a ship4. As it is discussed in the passage, the squeaks of bats can be functionally comparedwith ________.A. human languagesB. a mountainsideC. a shoal of fishD. taps on a ship5. Which of the following statements can be inferred from the passage?A. Animals are more intelligent than humans.B. Humans are more intelligent than animals.C. Animals are often compared with human inventions.D. Humans are often inspired by animals.英语四级阅读理解练习题答案1.[B] 主旨大意题。
6月英语四级阅读理解练习题附答案

20XX年6月英语四级阅读理解练习题附答案2017年6月英语四级阅读理解练习题:【原文】Nearly everyone agrees that money doesnt buy as much as it used to, no matter where you want to spend it. This is certainly true of the paper money that passes so quickly through ones hands. Inflation(通货膨胀) eats away at its buying power just as the steady appetite of waves chews at sand cliffs. But what about coins that seem to do very little except wear out your purses and pockets? Unlike notes, metal money becomes more valuable the longer it is held, especially if it is put away where it wont get scratched or worn. Why is this? One reason is that coins, being more durable, fall more readily into a category for collectors. Naturally, the rarer gold pieces must become more valuable as the price of this metal goes up.But, curiously, one of the rarest coins in the world is not made of gold, but of the relatively cheaper silver. In 1804, theUnited States mint(造币厂) struck 19,570 silver dollars. That is what its records show. Today only six of this original number remain and these are unlikely ever to reach the auction market. So what happened to some 19,564 large silver coins, not the easiest sort of things to lose? One of the more romantic theories is that they were part of the payment to Napoleon for the American territory then known as Louisiana. But they never reached France. Somewhere in the Gulf of Mexico, the ship transporting them was sunk, either by a storm or by pirates (#). The probable answer to the mystery is that they were melted down—since the silver value was greater than the actual value of the coin. What really happened to the rest will probably always remain a mystery. What is known is that whoever can come up with one will find himself instantly rich.2017年6月英语四级阅读理解练习题:【题目】26.

According to this passage, one of the rarest coins in the world is made ofA. silverB. goldC. copperD. paper29.

大学英语四级阅读理解练习题及答案
四级阅读理解When families gather for Christmas dinner, some will stick to formal traditions dating back to Grandma’s generation. Their tables will be set with the good dishes and silver, and the dress code will be Sunday-best.But in many other homes, this china--and--silver elegance has given way to stoneware (粗陶)--and--stainless informality, with dresses assuming an equally casual--Friday look. For hosts and guests, the change means greater simplicity and comfort. For makers of fine china in Britain, it spells economic hard times.Last week Royal Doulton, the largest employer in Stoke-onTrent, announced that it is eliminating 1,000 jobs--one-fifth of its total workforce. That brings to more than 4,000 the number of positions lost in 18 months in the pottery (陶瓷) region. Wedgwood and other pottery factories made cuts earlier.Although a strong pound and weak markets in Asia play a role in the downsizing, the layoffs in Stoke have their roots in earthshaking social shifts. A spokesman for Royal Doulton admitted that the company “has been somewhat slow in catching up with the trend”toward casual dining. Families eat together less often, he explained, and more people eat alone, either because they are single or they eat in front of television.Even dinner parties, if they happen at all, have gone causal. In a time of long work hours and demanding family schedules, busy hosts insist, rightly, that it’s better to share a takeout pizza on paper plates inthe family room than to wait for the perfect moment or a “real” dinner party. Too often, the perfect moment never comes, Iron a fine-pattened tablecloth? Forget it. Polish the silver? Who has time?Yet the loss of formality has its down side. The fine points of etiquette(礼节) that children might once have learned at the table by observation or instruction from parents and grandparents(“Chew with your mouth closed.”“keep your elbows off the table.”)must be picked up elsewhere. Some companies now offer etiquette seminars for employees who may be competent professionally but clueless socially.练习题:Choose correct answers to the question:1.The trend toward casual dining has resulted in ______A. bankruptcy of fine china manufacturersB. Shrinking of the pottery industryC. restructuring of large enterprisesD. Economic recession in Great Britain2.Which of the following may be the best reason for casual dining?A. Family members need more time to relax.B. Busy schedules leave people no time for formality.C. People want to practice economy in times of scarcity.D. Young people won’t follow the etiquette of the older generation.3.It can be learned from the passage that Royal Doulton is _______A. a retailer of stainless steel tablewareB. a dealer in stonewareC. a pottery chain storeD. a producer of fine china4.The main cause of the layoffs in the pottery industry is _______A. the increased value of the poundB. the economic recession in AsiaC. the change in people’s way of lifeD. the fierce competition at home and abroad5.Refined table manners, though less popular than before in current social life, _______A. are still a must on certain occasionsB. are bound to return sooner or laterC. are still being taught by parents at homeD. Can help improve personal relationships1.[B] 推理判断题。

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.

How much was it ?a. 60%b. 50%c. 33%d. 90%答案:cdabc大学英语四级阅读理解试题40篇之三(含答案)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大学英语四级阅读理解试题40篇之四(含答案)Today ,as in every other day of the year ,more than 3000 U.S. adlescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime,it can be expected that of these 3000 about 23 will be murdered,30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweithts all other factors, whether voluntary or involuntary, as a cause of death.Since the late 1970s, when daily smoking among high school seniors reached 30 precent , smoking rates among youth have declined . While the decline is impressive ,several important issues must be raised.First, in the past several years,smoking rates among youth have declined very little. Second,in the late 1970s ,smoking among male high school seniors exceeded that among female by nearly 10 percent . The statistic is reversing.Third ,several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent .Finally, thouth significant declines in adolescent smoking have occurred in the past decade,no definite reasons for the decline exist. Within this context,the Naional Cancer Instiute (NCI) began its current effort to determine the most effecive measures to reduce smoking levesl among youth.1.According to the author, the deaths among youth are mainly caused by _____.a.traffic accidentsb.smoking-related deseasec.murderd.all of these2.Every day there are over_____high school strdents who will become regular smoker.a.75b.23c.30d.30003.By "dropout" the author means______.a.students who failed the examinationb.students who left schoolc.students who lost their wayd.students who were driven out of school4.The reason for declining adolescent smoking is that ________.a.NCI has taken effective measuresb.smoking is prevented among high school seniorsc.there are many smokers who have died of cancerd.none of these5.What is implied but not stated by the author is that ________.a.smoking rates among youth have declined very littleb.there are now more female than male smokers among high school seniorsc.high smoking rates are due to the incease in wealthd.smoking at high school are from low socio-economic backgrounds答案:bdbdb大学英语四级阅读理解试题40篇之五(含答案)The food we eat seems to have profound effects on our health.Although science hasmade 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大学英语四级阅读理解试题40篇之六(含答案)As the pace of life continues to increase ,we are fast losing the art of relaxation. Once you are in the habit of rushing through lift,being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.Stress is an natural part of everyday lift and there is no way to avoid it. In fact ,it is not the bad thing it is often supposed to be .A certain amount of stress is vital to provide motivation adn give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress,and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress,in whatever form,we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme,but however little the stress,it involves the same response. It is when such a reaction lasts long,through continued exposure to stress,that health becomes endangered.Such serious conditions as high blood pressure and heart disease have established links with stress.Since we cannot remove stress from our lives(it would be unwise to do so even if we could),we need to find ways to deal with it.1.People are finding less and less time for relaxing themselves because_____.a.they do not know how to enjoy themselvesb.they do not believe that relaxation is important for healthc.they are travelling fast all the timed.they are becoming busier with their work2.According to the writer ,the most important character for a good manager is his ________.a.not fearing stressb.knowing the art of relaxationc.high sense of responsibilityd.having control over performance3.Which of the follwing statements is ture?a.We can find some ways to avoid stressb.Stress is always harmful to peoplec.It is easy to change the hagit of keeping oneself busy with work.d.Different people can withstand different amounts of stress4.In 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大学英语四级阅读理解试题40篇之七(含答案)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大学英语四级阅读理解试题40篇之八(含答案)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大学英语四级阅读理解试题40篇之九(含答案)As she walked round the huge department store,Edith reflected how difficult it was to choose a suitable Christmas present for her father.She wish that he was as easy to please as her mother, who was always delighted with perfumeBesides,shoppong at this time of the year was a most disgreeable experience :people trod on your toes,poked you with their elbows and almost knocked you overin their haste to get to a bargain ahead of you.Partly to have a rest, Edith paused in front of a counter where some attracive ties were on display. "They are real silk," the assistant assured her, trying to tempt her. "Worth double the price." But edit knew from past experience that her choice of ties hardly ever pleased her father.She moved on reluctantly and then quite by chance, stopped where a small crowd of man had gathered round a counter. She found some good quality pipes on sale-----and the prices were very reasonable. Edith did not hesitate for long : although her father only smoked a pipe occasionally, she knew that this was a present which was bund to please him.When she got home,with her small well-chosen present concealed in her handbag, her parents were already at the supper table. Her mother was in an especially cheerful mood, "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:dbdcd大学英语四级阅读理解试题40篇之十(含答案)If 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 thatdrives our cars,for example.Even if scientists develop new ways of feeding the human race,the crowded conditions on earth will make it necessary for lus to look for open space somewhere else. But none of the other planets in our solar system are capable of supporting life at present. One possible solution to the problem, however,has recently been suggested by American scientist, Professor Carl Sagan.Sagan believes that before the earth's resources are compleetely exhausted it will be possible to change the atmophere of Venus and so create a new world almost as large as earth itself. The difficult is that Venus is much hotter than the earth and there is only a tiny amount of water there.Sagan proposes that algae organisms that can live in extremely hot or cold atmospheres and at the same time produce oxygen,should be bred in condition similar to those on Venus.As soon as this has been done, the algae will be placed in small rockets. Spaceship will then fly to Venus and fire the rockets into the atmosphere .In a fairly short time, the alge will break down the carbon dioxide into oxygen and carbon. When the algae have done theri work, the atmosphere will become cooler,but befor man can set foot on Venus it will be neccessary for the oxygen to produce rain. The surface of the planet will still be too hot for man to land on it but the rain will eventually fall and in a few years something like earth will be reproduced on Venus.1.Inte long run, the most insoluble problem caused by population growth on earth will probably be the lack of ______.a.foodb.oilc.spaced.resources2.Carl Sagan believes that Venus might be colonized from earth because _____a.it might be possible to change its atmosphereb.its atmosphere is the same as the earth'sc.there is a good supply of water on Venusd.the days on Venus are long enough3.On Venus there is a lot of ________.a.waterb.carbon dioxidec.carbon monoxided.oxygen4.Algae are plants that can____.a.live in very hot temperaturesb.live in very cold temperaturesc.manufacture oxygend.all of the above5. Man can land on Venus only when_______.a.the algae have done their workb.the atmosphere becomes coolerc.thereis oxygend.it rains there答案:cabdd大学英语四级阅读理解试题40篇之十一(含答案)What is your favourite colour? Do you like yellow , orange ,red? If you do ,you must be an optimist, a leader, an active person who enjoys life, people and excitement. Do you prefer greys and blues? Then you are probably quiet,shy, and you would rather follow than lead. You tend to be a pessimist. At least, this is what psychologists tell us, and they should know,because they have been seriously studying the meaning of colours preference, as well as the effect that colours have on human beings. They tells us, among other facts,that we do not choose our favourite clour as we grow up----we are born with our preference.If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly. Colours do influence our moods----there is no doubt about it .A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand ,black is depressing. A black bridge over the Thames River, near London, used to be the scene of more suicides than any other bridge in the area ----until it was repainter green.The number of suicide attempts immediately fell sharply ;perhaps it would have fallen even more if the bridge had been done in pink or baby blue.Light and bright colours make people not only hppier but more active. It is an established fact that factory workers work better,harder ,and have fewer accidents when their machines are painted orange rather than black or grey.1."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."

英语四级阅读理解练习附答案详解Mom Is Best Weapon Against Drug AbuseA caring mother is the single most important factor in preventing teenagers from abusingdrugs and alcohol1.An international study showed that teenagers living with both parents are less likely to sufferfrom alcohol and drug problems but a strong maternal2 bond is the most effective barriertosubstance abuse."These findings suggest that living with both parents may inhibit drug use but only ifavailability through peer networks3 is not very high,"said Dr. Paul McArdle, of NewcastleUniversity innorthern England, who led the study. "They also suggestthatattachment,particularly to mothers, is a more potent inhibitor and that this is truly acrosscultures and substances."The report, which is published in the journal Addiction, involved nearly4 , 000 teenagers inEngland, Ireland, Italy, Germany and the Netherlands. They were questioned about their useofcannabis, amphetamines, ecstasy, LSD4, tranquilizers5 and alcohol.The teenagers also filled in questionnaires about their relationship with their parents andgrandparents, how well they were supervised after school and whether they were allowed tomeetfriends at home."Both the quality of family relationships and the structure of families appear to be significantinfluences on youth drug use. A strong maternal bond offers the greatest protectionagainstdeveloping drug habits."McArdle said in a statement.The rate of drug abuse among teenagers living with both parents and who had a goodrelationship with their mother was 16.6 percent. If either factor was missing the drug abuserate rose to 32percent.More than 42 percent of teenagers living in one parent families who did not have a strong bondwith their mother used drugs.Drug prevention campaigns in British schools and on television warn teenagers about thedanger of drugs and alcohol but McArdle said no one is tackling the issue of parentalresponsibility.练习题:Ⅰ.

英语四级长篇阅读练习题原文A) We are surrounded by so much paper and card that it is easy to forget just how complex it is. There are many varieties and grades of paper materials, and whilst it is fairly easy to spot the varieties, it is far more difficult to spot the grades.B) It needs to be understood that most paper and card is manufactured for a specific purpose, so that whilst the corn-flake packet may look smart, it is clearly not something destined for the archives. It is made to look good, but only needs a limited life span. It is also much cheaper to manufacture than high grade card.C) Paper can be made from an almost endless variety of cellulose-based material which will include many woods, cottons and grasses or which papyrus is an example and from where we get theword "paper". Many of these are very specialized, but the preponderance of paper making has been from soft wood and cotton or rags, with the bulk being wood-based.Paper from WoodD) In order to make wood into paper it needs to be broken down into fine strands. Firstly by powerful machinery and then boiled with strong alkalies such as caustic soda, until a fine pulp of cellulose fibers is produced. It is from this pulp that the final product is made, relying on the bonding together of the cellulose into layers. That, in a very small nutshell, is the essence of paper making from wood. However, the reality is rather more complicated. In order to give us our white paper and card, the makers will add bleach and other materials such as china clay and additional chemicals.E) A further problem with wood is that it contains a material that is not cellulose. Something called lignin. This is essential for the tree since it holds the cellulose fibres together, but if it is incorporated into the manufactured paper it presents archivists with a problem. Lignin eventually breaks down and releases acid products into the paper. This will weaken the bond between the cellulose fibers and the paper will become brittle and look rather brown and careworn. We have all seen this in old newspapers and cheappaperback books. It has been estimated that most paper back books will have a life of not greater than fifty years. Not what we need for our archives.F) Since the lignin can be removed from the paper pulp during manufacture, the obvious question is "why is it left in the paper?" The answer lies in the fact that lignin makes up a considerable part of the tree. By leaving the lignin in the pulp a papermaker can increase his paper yield from a tree to some 95%. Removing it means a yield of only 35%. It is clearly uneconomic to remove the lignin for many paper and card applications.G) It also means, of course, that lignin-free paper is going to be more expensive, but that is nevertheless what the archivist must look for in his supplies. There is no point whatsoever in carefully placing our valuable artifacts in paper or card that is going to hasten their demise. Acid is particularly harmful to photographic materials, causing them to fade and is some cases simply vanish!H) So, how do we tell a piece of suitable paper or card from one that is unsuitable? You cannot do it by simply looking, and rather disappointingly, you cannot always rely on the label. "Acid-free" might be true inasmuch as a test on the paper may indicate that it is a neutral material at this time. But lignin can take years before it starts the inevitable process of breaking down, and in the rightconditions it will speed up enormously.I) Added to this, as I have indicated earlier, paper may also contain other materials added during manufacture such as bleach, china clay, chemical whiteners and size. This looks like a bleak picture, and it would be but for the fact that there are suppliers who will guarantee the material that they sell. If you want to be absolutely sure that you are storing in, or printing on, the correct material then this is probably the only way.J) Incidentally, acids can migrate from material to material. Lining old shoe boxes with good quality acid-free paper will do little to guard the contents. The acid will get there in the end. Paper from RagK) Paper is also commonly made from cotton and rag waste. This has the advantage of being lignin-free, but because there is much less cotton and rag than trees, it also tends to be much more expensive than wood pulp paper. You will still need to purchase from a reliable source though, since even rag paper and card can contain undesirable additives.L) A reliable source for quality rag papers is a recognized art stockiest. Many water color artists insist on using only fine quality rag paper and board.M) The main lesson to learn from this information is that youcannot rely on purchasing archival materials from the high street. The only safe solution is to purchase from specialist suppliers. It may cost rather more, but in the end you will know that your important and valuable data and images have the best home possible.英语四级长篇阅读练习题选项1. The corn-flake packet is cheaper than high grade card.2. There are a lot of materials which can be used for making paper, but the superiority ones are soft wood, cotton and rags.3. During the whole manufacturing process, the final product is made from a pulp of cellulose fibres.4. In order to make white paper and card, the makers will add bleach.5. Liguin is essential for the tree but it will make paper easy to break.6. Many paper producers will preserve lignin during manufacture, because leaving the lignin will make more paper from a tree.7. Acid is particularly harmful to photographic materials.8. If the lignin is removed from the paper, the paper will be more expensive.9. Although free of lignin, paper made from cotton and rag waste can also cost more money than wood pulp paper because there is much less cotton and rag than trees.10. What we can learn from "Paper from Rag" is that you had better buy archival materials from specialist suppliers.英语四级长篇阅读练习题答案:1.B根据题干中的信息提示词corn—flake packet,high grade card,可定位到文章第二段,该部分最后提到corn-flake packet在制造过程中比高等级的纸(high grade card)便宜.2.C根据题干中的信息提示词soft wood,cotton and rags,可定位到文章第三段最后一句。

第 1 页 共 5 页 四级考试英语阅读理解精选题附答案 四级考试英语阅读理解精选题(一) Communications technologies are far from equal when it comes to conveying the truth. The first study to compare honesty across a range of communication media has fund that people are twice as likely to tell lies in phone conversations as they are in emails. The fact that emails are automatically recorded—and can come back to haunt (困扰) you—appears to be the key to the finding. Jeff Hancock of Cornell University in Ithaca, New York, asked 30 students to keep a communications diary for a week. In it they noted the number of conversations or email e某changes they had lasting more than 10 minutes, and confessed to how many lies they told. Hancock then worked out the number of lies per conversation for each medium. He found that lies made up 14 per cent of emails, 21 per cent of instant messages, 27 per cent of face-to-face interactions and an astonishing 37 per cent of phone calls. His results to be presented at the conference on human-computer interaction in Vienna, Austria, in April, have surprised psychologists. Some e某pected emailers to be the biggest liars, reasoning that because deception makes people uncomfortable, the detachment (非直接接触) of emailing would make it easier to lie. Others e某pected people to lie more in face-to-face e某changes because we are most practised at that form of communication. But Hancock says it is also crucial whether a conversation is being recorded and could be reread, and whether it occurs in real time. People appear to be afraid to lie when they know the communication could later be used to hold them to account, he says. This is why fewer lies appear in email than on the phone. 第 2 页 共 5 页
People are also more likely to lie in real time—in a instant message or phone call, say—than if they have time to think of a response, says Hancock. He found many lies are spontaneous (脱口而出的) responses to an une某pected demand, such as: “Do you like my dress?” Hancock hopes his research will help companies work our the best ways for their employees to communicate. For instance, the phone might be the best medium foe sales where employees are encouraged to stretch the truth. But, given his result, work assessment where honesty is a priority, might be best done using email. 57. Hancock’s study focuses on ________. A) the consequences of lying in various communications media B) the success of communications technologies in conveying ideas C) people are less likely to lie in instant messages D) people’s honesty levels across a range of communications media 58. Hancock’s research finding surprised those who believed that ________. A) people are less likely to lie in instant messages B) people are unlikely to lie in face-to-face interactions C) people are most likely to lie in email communication D) people are twice as likely to lie in phone conversations 59. According to the passage, why are people more likely to tell the truth through certain media of communication? A) They are afraid of leaving behind traces of their lies. B) They believe that honesty is the best policy. C) They tend to be rela某ed when using those media. D) They are most practised at those forms of communication. 第 3 页 共 5 页
60. According to Hancock the telephone is a preferable medium for promoting sales because ________. A) salesmen can talk directly to their customers B) salesmen may feel less restrained to e某aggerate C) salesmen can impress customers as being trustworthy D) salesmen may pass on instant messages effectively 61. It can be inferred from the passage that ________. A) honesty should be encouraged in interpersonal communications B) more employers will use emails to communicate with their employees C) suitable media should be chosen for different communication purposes D) email is now the dominant medium of communication within a company 四级考试英语阅读理解精选题答案 57.

C 四级考试英语阅读理解精选题(二) As we have seen, the focus of medical care in our society has been shifting from curing disease to preventing disease—especially in terms of changing our many unhealthy behaviors, such as poor eating habits, smoking, and failure to e某ercise. The line of thought involved in this shift can be pursued further. Imagine a person who is about the right weight, but does not eat very nutritious (有营养的) foods, who feels OK but e某ercises only occasionally, who goes to work every day, but is not an outstanding worker, who drinks a few beers at home most nights but does not drive while drunk, and who has no chest pains or abnormal blood counts, but sleeps a lot and often feels tired. This person is not ill. He may
