大学英语四级阅读理解试题及答案解析
大学英语四级阅读理解试题及答案（一）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. 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 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 goal答案：adcbc二The 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 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 shreof 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 nationaleconomy 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,saidit 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 schoolseniorsc.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 aresimply 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 ofvegetables.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：cacbdWhat 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 aswe 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." "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 to others because of _______.a.its shapeb.its structurec.its colourd.its building materials答案：bcaac十二Social customs and ways of behaving change. Things which were considered impolite many years ago are now acceptable. Just a few years ago, it was considered impolite behaviour for a man to smoke on street. No man who thought of himself by smoking when a lady was in a room.Customs also differ from country to country. Does a man walk on the left or the right of a woman in your country? Or doesn't it matter? Should you use both hands when you are eating? Should leave one in your lap,or on the table?The Americans and the British not only speak the same language but also share a large number of social customs. For example, in both America and England people shake hands when they meet each other for the first time. Also, most Englishmen will open a door for a wonman or offer their seat to a woman , and so will most Americans. Promptness is important both in England and in America. That is , if a dinner invitation is for 7 o'clock , the dinner guest either arrives close to that time or calls up to explain his delay.The important thing to remember about social customs is not to do anything that might make other people feel uncomfortable-----especially if they are your guests. When the food wasserved , one of the guests strated to eat his peas with a knife . The other guests were amused or shocked , but the host calmly picked up his knife and began eating in the same way. It would have been bad manners to make his guest feel foolish or uncomfortable.1.If one has accepted a dinner invitation ,what should he do if he is tobe late for the dinner?a.He should find an excuseb.He should adk for excuse.c.He should say sorryd.He should telephone to explain his being late.2."It would have been bad manners to make his guests feel foolish or uncomfortable." "Bad manners " means ________.a.uglyb.dishonestc.impolited.shameful3.which of the following do you think is the best tiltle for this passage?a.Social Customs and Customsb.Social Lifec.American and British Customsd.Promptness Is Important4.According to the text, the best host_______.a.tries his best to make his guests feel comfortableb.makes his guests feel excitedc.tries to avoid being naughty to his guestsd.tries to avoid being foolish5.The author of this article may agree with which of the following?a.The guest who ate his peas with a knifeb.The other guests who were amused or shockedc.The host who picked up his knife and began eating in the same wayd.None of the above答案：dcaac十三New Orleans, Louisiana, was established as part of the French Empire in 1718.Its location on the east bank of the Mississippi River gave it control of the American hinerland and it became strategically important to many nations. It was transferred from France to Spain, returned to France,and finally sold by Napoleon to the United States in 1803. The city was the site of a famous battle fought in 1815 between the British, who hoped to control it , and the Americans under General And rew Jackson.The riverbed of the Mississippi is constantly silting and the river isnow actually higher than the city. Levees hold back the river and giant pumps are used to move water from the city into the river.Although New Orleans haas beena part of the United States for almost two centuries, its population takes great pride in its French heritage. Louisiana still retains parts of the Code Napoleon which,form many years,was its only law.New Orleans is carefree city and it boasts its hot, spicy Creole seafood and its native Dixieland Jazz. The jackson Square neighborhood maintains its French colonial homes and in other sections are pre-Civil War mansions. Visitors are surprised to find that behind this interesting facade of yesteryear, is a busy industrial and port city. Grain and coal come from the Midwest and foreigh cargoes are unloaded here. New Orleans is no longer a sleepy Southern town----but it's still fun to visit.1.What accounts for the levees and pumps in New Orleans?a.The Mississippi frequently floods the city.b.The riverbed has raised inthe past 200 years.c.The torrential rains flood the city frequently.d.The high humidity cannot otherwise be comtrolled.2.The battle of New Orleans was fought by jackson against______.a.Franceb.Britainc.Spaind.The North3.The Code Napoleon was _______.a.an agreement to sell Louisianab.a body of lawsc.a city pland.a military code for the army4.Which of the following elements does not apply to the attiude of the inhabitants of New Orleans?a.Pride in their French heritage.b.A desire to retain picturesque colonial buildings.c.A refusal to engage in trade and commerced.A praising of Dixieland Jazz.5.Tourists visiting New Orleans are surprised to encounter_____.a.Creole foodb.Dixieland jazzc.bustling cityd.authentic colonial homes答案：bbbcc十四The United States is on the verge of losing its leading place in the world's technology. So says more than one study in recent years. One of the reasons for this decline is the parallel decline in the number of U.S.scientists and engineers.Since 1976,employment of scientists and engineers is up 85 percent. This trend is expected to continue. However, the trend shows that the number of 22-year-olds--the near term source of future PH.D.s-is declining. Further adding to the problem is the increased competition for these candidates from other fields-law,medicine,business,etc. While the number of U.S. PH.D.s in science and engineering declines,the award of PH.D.s to foreign nationals is increasing rapidly.Our inability to motivate students to pursue science and engineering careers at the graduate level is compounded because of the intense demand industry has for bright Bachelor's and Master's degree holders. Too often, promising PH.D.candidates, confronting the cost and financial sacrifice of pursuing their education,find the attraction of industry irresistible.1.The U.S.will come to lose its leading place in technology probably because ________.a. the number of PH.D. degree holders is decliningb. the number of scientists and engineers is decreasingc. the number of 22-year-ilds is decliningd. scientists and engineers are not employed2.The field of science and engineering is facing a competition from ________ .a. technologyb. foreign nationalsc. such fields as law, medicine and businessd. postgraduatesrge-scale enterprises now need _______.a. bright graduates and postgraduatesb. new inventionsc. advanced technologyd. engineers4.Many promising postgraduates are unwilling to pursue a PH.D. degree because _________.a. they are not encouraged to be engaged in scienceb. industry does not require PH.D. holdersc. they have financial difficultiesd. they will spend much time and energy completing PH.D.5.PH.D. candidates "find the attraction of industry irresistible" means that _________.a. they find industry is attracting more and more college studentsb. they don't think they can prevent themselves from working for industryc. they cannot resist any attraction from all sidesd. they cannot work for industry any longer答案：bcadb十五Newdays,a standard for measuring power has changed.These changes foretell a new standard for measuring power.No longer will a nation's political influence be based solely on the strength of its military forces. Of course, military effectiveness will remain a primary primary measure of power.But political influence is also closely tied to industrial competitiveness. It's often said that without its military the Soviet Union would really be a third-world nation. The new standard of opwer and influence that is evolving now places more emphasis on the ability of a country to compete effectively in the economic markets of the world.America must recognize this new course of events. Our success in shaping world events over the past 40 years has been the direct result of our ability to adapt technology and to take advantage of the capabilities of our people for the purpose of maintaining peace. Our industrial prowess over most of this period was unchallenged. It is ironic that it is just this prowess that has enabled other countries to prosper and in turn to threaten our industrial leadership.The competitiveness of America's industrial base is an issue bigger than the Department of Defense and is going to require the efforts of the major institutional forces in our society-government,industry,and education. That is not to say that the Defense Department will not be astrong force in the process because we will. But we simply cannot be, nor should we be, looked upon by others as the savior of American industry.1. Now a nation's political influence depends on _________.a. the strength of its military forcesb. its ability to compete in industryc. economic marketsd. both a and b2. The Soviet Union was not listed as a third-world nation just because of _________.a. its powerful military forcesb. its vast landc. its industrial competitivenessd. its contributions to world peace3. The author indicates that ______ is threatening American political power.a. other countriesb. the declining U.S. industrial basec. a new standard for measuring powerd. less advanced technology4. America succeeded in shaping world events over past 40 years probably because of ___________.a. its ability to adapt technologyb. its ability to take advantage of the capabilities of its peoplec. its ability to compete in the world marketsd. both a and b5. The purpose of writing this article is __________.a. to draw the readers' attention to a new standard for measuring powerb. to demonstrate American political influence in the worldc. to emphasize that efforts must be made to strengthen the declining U.S. industrial based. to show American industrial prowess答案：dabdc。

英语四级考试阅读精选题及答案讲解英语四级考试阅读精选题(一)Some houses are designed to be smart. Others have smart designs. An e某ample of the secondtype of house won an Award of E某cellence from the American Institute of Architects.Located on the shore of Sullivan’s Island off the coast of South Carolina, the award-winningcube-shaped beach house was built to replace one smashed to pieces by Hurricane (飓风) Hugo10 years ago. In September1989, Hugo struck South Carolina, killing 18 people and damagingor destroying 36,000 homes in the state.Before Hugo, many new houses built along South Carolina’s shoreline were poorly constructed,and enforcement of building codes wasn’t strict, according to architect Ray Huff, who createdthe cleverly-designed beach house. In Hugo’s wake, all new shoreline houses are required tomeet stricter, better-enforced codes.The new beach house on Sullivan’s Island should be able towithstand a Category 3 hurricane with peak winds of 179 to 209 kilometers per hour.At first sight, the house on Sullivan’s Island looks anything but hurricane-proof. Its redwoodshell makes it resemble “a large party lantern (灯笼)” at night, according to one observer. Butlooks can be deceiving. The house’s wooden frame is reinforced with long steel rods to give ite某tra strength.To further protect the house from hurricane damage, Huff raised it 2.7 meters off the groundon timber pilings—long, slender columns of wood anchored deep in the sand. Pilings mightappear insecure, but they arestrong enough to support the weight of the house. They alsoelevate the house above storm surges. The pilings allow thesurges to run under the houseinstead of running into it. “These swells of water come ashore at tremendous speeds and causemost of the damage done to beach-front buildings,” said Huff.Huff designed the timber pilings to be partially concealed by the house’s ground-to-roofshell. “ The shell masks the pilings so that the house doesn’t look like it’s standing with itspant legs pulled up,” said Huff. In the event of a storm surge, the shell should break apart andlet the waves rush under the house, the architect e某plained.练习题：Choose correct answers to the question:1. After the tragedy caused by Hurricane Hugo, new houses built along SouthCarolina’s shore line are required ________.A. to be easily reinforcedB. to look smarter in designC. to meet stricter building standardsD. to be designed in the shape of cubes2. The award-winning beach house is quite strong because________.A. it is strengthened by steel rodsB. it is made of redwoodC. it is in the shape of a shellD. it is built with timber and concrete3. Huff raised the house 2.7 meters off the ground on timber pilings in order to________.A. withstand peak winds of about 200 km/hrB. anchor stronger pilings deep in the sandC. break huge sea waves into smaller onesD. prevent water from rushing into the house4. The main function of the shell is ________.A. to strengthen the pilings of the houseB. to give the house a better appearanceC. to protect the wooden frame of the houseD. to slow down the speed of the swelling water5. It can be inferred from the passage that the shell should be ________.A. fancy-lookingB. waterproofC. easily breakableD. e某tremely strong英语四级考试阅读精选题答案1.[C] 根据题目中的专有名词Hugo查找到文中第3段第2句。

英语四级阅读题库含答案解析1.Passage OneGlobal warming may or may not be the great environmental crisis of the 21st century, but regardless of whether it is or isn’t –we won’t do much about it. We will argue over it and may even, as a nation, make some fairly solemn-sounding commitments to avoidit. But the more dramatic and meaningful these commitments seem, the less likely theyare to be observed.Al Gore calls global warming an “inconvenient truth,”as if merely recognizing it could put us on a path to a solution. But the real truth is that we don’t know enough to relieve global warming, and –without major technological breakthroughs—we can’t do much about it.From 2003 to 2050, the world’s population is projected to grow from 6.4 billion to 9.1 billion, a 42% increase. If energy use per person and technology remain the same, totalenergy use and greenhouse gas emissions (mainly, CO2) will be 42% higher in 2050. butthat’s too low, because societies that grow richer use more energy. We need economicgrowth unless we condemn the world’s poor to their present poverty and freeze everyone else‘s living standards. With modest growth, energy use and greenhouse emissions more than double by 2050.No government will adopt rigid restrictions on economic growth and personal freedom (limits on electricity usage, driving and travel) that might cut back global warming. Still, politicians want to show they’re “doing something.”Consider the Kyoto Protocol (京都议定书). It allowed countries that joined to punish those that didn’t. But it hasn’t reduced CO2 emissions (up about 25% since 1990), and many signatories (签字国) didn’t adopt tough enough policies to hit their 2008-2012 targets.The practical conclusion is that if global warming is a potential disaster, the only solution is new technology. Only an aggressive research and development program might find ways of breaking dependence on fossil fuels or dealing with it.The trouble with the global warming debate is that it has become a moral problem whenit’s really an engineering one. The inconvenient truth is that if we don’t solve the engineering problem, we’re helpless.57. What is said about global warming in the first paragraph?A) It may not prove an environmental crisis at all. B) It is an issue requiring world wide commitments.C) Serious steps have been taken to avoid or stop it. D) Very little will be done to bring it under control.58. According to the author’s understanding, what is Al Gore’s view on global warming?A) It is a reality both people and politicians are unaware of.B) It is a phenomenon that causes us many inconveniences.C) It is a problem that can be solved once it is recognized.D) It is an area we actually have little knowledge about.59. Green house emissions will more than double by 2050 because of _______.A) economic growthB) the widening gap between the rich and poor C) wasteful use of energyD) the rapid advances of science and technology60. The author believes that, since the signing of the Kyoto Protocol, ________.A) politicians have started to do something to better the situationB) few nations have adopted real tough measures to limit energy useC) reductions in energy consumption have greatly cut back global warmingD) international cooperation has contributed to solving environmental problems61. What is the message the author intends to convey?A) Global warming is more of a moral issue than a practical one.B) The ultimate solution to global warming lies in new technologyC) The debate over global warming will lead to technological breakthroughs.D) People have to give up certain material comforts to stop global warming.Passage TwoSomeday a stranger will read your e-mail without your permission or scan the Websites you’ve visited. Or perhaps someone will casually glance through your creditcard purchase or cell phone bills to find out your shopping preferences or calling habits.In fact, it’s likely some of these things have already happened to you. Who wouldwatch you without your permission? It might be a spouse, a girlfriend, a marketing company, a boss, a cop or a criminal. Whoever it is, they will see you in a way you neverintended to be seen —the 21st century equivalent of being caught naked.Psychologists tell us boundaries are healthy, that it’s important to reveal yourself to friends, family and lovers in stages, at appropriate times. But few boundaries remain. Thedigital bread crumbs(碎屑) you leave everywhere make it easy for strangers to reconstruct who you are, where you are and what you like. In some cases, a simpleGoogle search can reveal what you think. Like it or not, increasingly we live in a worldwhere you simple cannot keep a secret.The key question is: Does that matter?When opinion polls ask Americans about privacy, most say they are concerned aboutlosing it. A survey found an overwhelming pessimism about privacy, with 60 percent of respondents saying they feel their privacy is “slipping away, and that bothers me.”But people say one thing and do another. Only a tiny fraction of Americans changeany behaviors in an effort to preserve their privacy. Few people turn down a discount attollbooths(收费站) to avoid using the EZ-Pass system that can track automobile movements. And few turn down supermarket loyalty cards. Privacy economist Alessandro Acquisti has run a series of tests that reveal people will surrender personalinformation like Social Security numbers just to get their hands on a pitiful 50-cents-offcoupon (优惠券).But privacy does matter –at least sometimes. It’s like health: When you have it, you don’t notice it. Only when it’s gone do you wish you’d done more to protect it.62. What does the author mean by saying “the 21st century equivalent of being caught naked ”(Lines 3-4, Para.2)?A) People’s personal information is easily accessed without their knowledge.B) In the 21st century people try every means to look into others’secrets.C) People tend to be more frank with each other in the information age.D) Criminals are easily caught on the spot with advanced technology.63. What would psychologists advise on the relationships between friends?A) Friends should open their hearts to each other.B) Friends should always be faithful to each other. C) There should be a distance even between friends.D) There should be fewer disputes between friends.64. Why does the author say “we live in a world where you simple cannot keep a secret”(Line 5, Para.3)?A) Modern society has finally evolved into an open society.B) People leave traces around when using modern technology.C) There are always people who are curious about others’affairs.D) Many search engines profit by revealing people’s identities.65. What do most Americans do with regard to privacy protection?A) They change behaviors that might disclose their identity.B) They use various loyalty cards for business transactions.C) They rely more and more on electronic devices. D) They talk a lot but hardly do anything about it.66. According to the passage, privacy is like health in that ________.A) people will make every effort to keep itB) its importance is rarely understoodC) it is something that can easily be lostD) people don’t cherish it until they lose it2.Passage OneQuestions 57 to 61 are based on the following passage.If you are a male and you are readingthis ,congratulations: you are a survivor .According to statistics .you are more than twice as likely to die of skin cancer than a woman ,and nine times more likely to die of AIDS. Assuming youmake it to the end of your natural term, about 78 years for men in Australia, you will die on average five years before a woman.There are many reasons for this-typically, men take more risks than woman and are more likely to drink and smoke but perhaps more importantly, men don’t go to the doctor.“Men aren’t seeing doctors as oftenas they should, ”says Dr. Gullotta, “This is particularly so for the over-40s,when diseases tend to strike.”Gullotta says a healthy man should visit the doctor every year or two. For those over 45,it should be at least once a year.Two months ago Gullotta saw a 50-year-old ma who had delayed doing anything about his smoker’s cough for a year.“When I finally saw him it had alreadyspread and he has since died from lung cancer”he says, “Earlier detection and treatment may not have cured him, but itwould have prolonged this life”According to a recent survey, 95%of women aged between 15 and early 40s see a doctor once a year, compared to 70% of men in the same age group.“A lot of men think they are invincible（不可战胜的）”Gullotta says “They only come in when a friend drops dead on thegolf course and they think”Geez, if it could happen to him.Then there is the ostrich approach,”some men are scared of what might be there and would rather not know, ”says Dr. Ross Cartmill.“Most men get their cars serviced more regularly than they service their bodies,”Cartmill says .He believes most diseases that commonly affect men couldbe addressed by preventive check-ups.Regular check-ups for men would inevitably place strain on the public purse, Cartmill says.”But prevention is cheaperin the long run than having to treat the diseases. Besides, the ultimate cost is far greater: it is called premature death.”57.Why does the author congratulate his male readers at the beginning of the passage?A. They are more likely to survive serious diseases today.B. Their average life span has been considerably extended.C. They have lived long enough to read this article.D. They are sure to enjoy a longer and happier live.58.What does the author state is the most important reason men die five years earlier on average than women?A. men drink and smoke much more than womenB. men don’t seek medical care as oftenas womenC. men aren’t as cautions as women in face of dangerD. men are more likely to suffer from fatal diseases59. Which of the following best completesthe sentence “Geez, if it could happen to him…’(line2,para,8)?A. it could happen to me, tooB. I should avoid playing golfC. I should consider myself luckyD. it would be a big misfortune60what does Dr. Ross Cartmill mean by “the ostrich approach”(line q para.9)A. a casual attitude towards one’s health conditionsB. a new therapy for certain psychological problemsC. refusal to get medical treatment for fearof the pain involvedD. unwillingness to find out about one’s disease because of fear61. What does Cartmill say about regularcheck-ups for men?A.They may increase public expensesB.They will save money in the long runC.They may cause psychological strains on menD.They will enable men to live as long as womenPassage TwoQuestions 62 to 66 are based on the following passage.High-quality customer service is preached(宣扬) by many ,but actually keeping customers happy is easier said than doneShoppers seldom complain to the manager or owner of a retail store, but instead will alert their friends, relatives, co-workers, strangers-and anyone who will listen.Store managers are often the last tohear complaints, and often find out only when their regular customers decide t frequent their competitors, according to astudy jointly conducted by Verde group and Wharton school“Storytelling hurts retailers and entertains consumers,”said Paula Courtney, President of the Verde group.”the store loses the customer, but the shopper must also find a replacement.”On average, every unhappy customerwill complain to at least four other, and will no longer visit the specific store for every dissatisfied customer, a store will lose up to three more due to negative reviews. The resulting “snowball effect”can be disastrous to retailers.According to the research, shoppers who purchased clothing encountered themost problems. ranked second and third were grocery and electronics customers.The most common complaints include filled parking lots, cluttered (塞满了的) shelves, overloaded racks, out-of-stock items, long check-out lines, and rude salespeople.During peak shopping hours, some retailers solved the parking problems by getting moonlighting（业余兼职的）local police to work as parking attendants. Some hired flag wavers to direct customers to empty parking spaces. This guidance eliminated the need for customers to circle the parking lot endlessly, and avoided confrontation between those eyeing the same parking space.Retailers can relieve the headaches by redesigning store layouts, pre-stocking sales items, hiring speedy and experienced cashiers, and having sales representatives on hand to answer questions.Most importantly, salespeople shouldbe diplomatic and polite with angry customers.“Retailers who’re responsive and friendly are more likely to smooth over issues than those who aren’t so friendly.”said Professor Stephen Hoch. “Maybe something as simple as a greeter at the store entrance would help.”Customers can also improve future shopping experiences by filing complaintsto the retailer, instead of complaining to the rest of the world. Retailers are hard-pressed to improve when they haveno idea what is wrong.注意：此部分试题请在答题卡2上作答62. Why are store managers often the lastto hear complaints?A Most customers won’t bother to complain even if they have had unhappy experiences.B Customers would rather relate their unhappy experiences to people around them.C Few customers believe the service will be improved.D Customers have no easy access to store managers.63. What does Paula Courtney imply by saying “…the shopper must also find a replacement”(Line 2, Para. 4)?A New customers are bound to replace old ones.B It is not likely the shopper can find thesame products in other stores.C Most stores provide the sameD Not complaining to the manager causesthe shopper some trouble too.64. Shop owners often hire moonlightingpolice as parking attendants so that shoppers_____A can stay longer browsing in the storeB won’t have trouble parking their carsC won’t have any worries about securityD can find their cars easily after shopping65. What contributes most to smoothing over issues with customers?A Manners of the salespeopleB Hiring of efficient employeesC Huge supply of goods for saleD Design of the store layout.66. To achieve better shopping experiences, customers are advised to _________.A exert pressure on stores to improve their serviceB settle their disputes with stores in a diplomatic wayC voice their dissatisfaction to store managers directlyD shop around and make comparisons between stores3. The January fashion show, called Future Fashion , exemplified howfar green design has come. Organized by the New York-based nonprofitEarth Pledge, the show inspired many top designers to work with sustainable fabrics for the first time. Several have since made pledges toinclude organic fabrics in their lines.The designers who undertake green fashion still face many challenges. Scott Hahn, cofounder with Gregory of Rogan and Loomstate,which uses all-organic cotton, says high-quality sustainable materials canstill be tough to fine . “Most designers with existing labels are findingthere aren’t comparable fabrics that can just replace what you’re doing and shat your customers are used to,”he says. For example, organic cotton and non-organic cotton are virtually indistinguishable once woven into a dress. But some popular synthetics, like stretch nylon, stillhave few eco-friendly equivalents.Those who do make the switch are finding they have more support.Last year the influential trade show Designers & Agents stopped charging its participation fee for young green entrepreneurs(企业家) who attend its two springtime shows in Los Angeles and New York and gavespecial recognition to designers whose collections are at least 25% sustainable . It now counts more than 50 green designers, up from fewerthan a dozen two years ago. This week Wal-Mart is set to announce amajor initiative aimed at helping cotton farmers go organic: it will buytransitional(过渡型的) cotton at higher prices , thus helping to expand thesupply of a key sustainable material . “Mainstream is about to occur,”says Hahn.Some analysts(分析师) are less sure . Among consumers, only 18%are even aware that ecofashion exists, up from 6% four years ago.Natalie Hormilla, a fashion writer, is an example of the unconverted consumer, when asked if she owned any sustainable clothes, she replied:“Not that I’m aware of.”Like most consumers, she finds little time to shop, and when she does, she’s on the hunt for “cute stuff that isn’t too expensive.”By her own admission, green just isn’t yet on her mind. But–thanks to the combined efforts of designers, retailers and suppliers –one day it will be.57. What is said about Future Fashion?A) It inspired many leading designers to start going green.B) It showed that designers using organic fabrics would go far.C) It served as an example of how fashion shows should be organized.D) It convinced the public that fashionable clothes should be madedurable.58. According to Scott Hahn, one big challenge to designers who will goorganic is that .A) much more time is needed to finish a dress using sustainablematerials .B) they have to create new brands for clothes made of organicmaterials .C) customers have difficulty telling organic from non-organicmaterials .D) quality organic replacements for synthetics are not readilyavailable .59. We learn from Paragraph 3 that designers who undertake greenfashion .A) can attend various trade shows free .B) are readily recognized by the fashion worldC) can buy organic cotton at favorable prices .D) are gaining more and more support .60. What is Natalie Hormilla’s attitude toward ecofashion?A) She doesn’t seem to care about it. C) She is doubtful of itspractical value.B) She doesn’t think it is sustainable D) She is very muchopposed to the idea61. What does the author think of green fashion?A) Green products will soon go mainstream.B) It has a very promising future.C) Consumers have the final say.D) It will appeal more to young people.Passage TwoQuestions 62 to 66 are based on the following passage.Scientists have devised a way to determine roughly where a personhas lived using a strand(缕) of hair , a technique that could help track the movements of criminal suspects or unidentified murder victims .The method relies on measuring how chemical variations in drinkingwater show up in people’s hair.“You’re what you eat and drink, and that’s recorded in you hair,”said Thure Cerling, a geologist at the University of Utah.While U.S diet is relatively identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as raid clouds move.Most hydrogen and oxygen atoms in water are stable , but traces ofboth elements are also present as heavier isotopes (同位素) . The heaviest raid falls first .As a result, storms that form over the Pacific deliver heavierwater to California than to Utah.Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand ofhair, scientists can construct a geographic timeline. Each inch of hair corresponds to about two months.Cerling’s team collected tap water samples from 600 cities and constructed a mop of the regional differences. They checked the accuracy of the map by testing 200 hair samples collected from 65 barber shops.They were able to accurately place the hair samples in broad regionsroughly corresponding to the movement of raid systems.“It’s not good for pinpointing (精确定位),”Cerling said . “It’s good for eliminating many possibilities.”Todd Park, a local detective, said the method has helped him learnmore about an unidentified woman whose skeleton was found near Great Salt Lake.The woman was 5 feet tall. Police recovered 26 bones, a T-shirt andseveral strands of hair.When Park heard about the research, he gave the hair samples to the researchers. Chemical testing showed that over the two years before herdeath, she moved about every two months.She stayed in the Northwest, although the test could not be morespecific than somewhere between eastern Oregon and western Wyoming.“It’s still a substantial area,”Park said “But it narrows it way down for me.”62. What is the scientists’new discovery?A) One’s hair growth has to do with the amount of water they drink.B) A person’s hair may reveal where they have lived.C) Hair analysis accurately identifies criminal suspects.D) The chemical composition of hair varies from person to person.63. What does the author mean by “You’re what you eat and drink”(Line 1, Para.3)?A) Food and drink affect one’s personality development.B) Food and drink preferences vary with individuals.C) Food and drink leave traces in one’s body tissues.D) Food and drink are indispensable to one’s existence.64. What is said about the rainfall in America’s West?A) There is much more rainfall in California than in Utah.B) The water it delivers becomes lighter when it moves inland.C) Its chemical composition is less stable than in other areas.D) It gathers more light isotopes as it moves eastward.65. What did Cerling’s team produce in their research?A) A map showing the regional differences of tap water.B) A collection of hair samples from various barber shops.C) A method to measure the amount of water in human hair.D) A chart illustrating the movement of the rain system.66. What is the practical value of Cerling’s research?A) It helps analyze the quality of water in different regions.B) It helps the police determine where a crime is committed.C) It helps the police narrow down possibilities in detective work.D) It helps identify the drinking habits of the person under investigation.4.Throughout this long, tense election, everyone has focused on the presidential candidates and how they’ll change America. Rightly so, but selfishly, I’m more fascinated by Michelle Obama and what she might beable to do, not just for this country, but for me as an African-Americanwoman. As the potential First Lady, she would have the world’s attention. And that means that for the first time people will have a chance to get upclose and personal with the type of African-American woman they so rarely see.Usually, the lives of black women go largely unexamined. The prevailing theory seems to be that we’re all hot-tempered single mothers who can’t keep a man. Even in the world of make-believe, black women still can’t escape the stereotype of being eye-rolling, oversexed females raised by our never-married, alcoholic (酗酒的) mothers.These images have helped define the way all women are viewed, including Michelle Obama. Before she ever gets the chance to commit toa cause, charity or foundation as First Lady, her most urgent and perhapsmost complicated duty may be simple to be herself.It won’t be easy. Because few mainstream publications have donein-depth features on regular African-American women, little is known about who we are, what we think and what we face on a regular basis.For better or worse, Michelle will represent us all.Just as she will have her critics, she will also have millions of fans who usually have little interest in the First Lady. Many African-American blogshave written about what they’d like to see Michelle bring to the White House—mainly showing the world that a black woman can support herman and raise a strong black family. Michelle will have to work to please everyone—an impossible task. But for many African-American women like me, just a little of her poise (沉着), confidence and intelligence will goa long way in changing an image that’s been around for far too long.57. Why does Michelle Obama hold a strong fascination for the author?A) She serves as a role model for African women.B) She possesses many admirable qualities becoming a First Lady.C) She will present to the world a new image of African-American women.D) She will pay closer attention to the interests of African-Americanwomen.58. What is the common stereotype of African-American women according to the author?A) They are victims of violence. B) They are of an inferior violence.C) They use quite a lot of body language. D) They live on charity andsocial welfare.59. What do many African-Americans write about in their blogs?A) Whether Michelle can live up to the high expectations of her fans.B) How Michelle should behave as a public figure.C) How proud they are to have a black woman in the White House.D) What Michelle should do as wife and mother in the White House.60. What does the author say about Michelle Obama as a First Lady?A) However many fans she has, she should remain modest,B) She shouldn’t disappoint the African-American community.C) However hard she tries, she can’t expect to please everybody.D) She will give priority to African-American women’s concerns.61. What do many African-American women hope Michelle Obamawill do?A) Help change the prevailing view about black women.B) Help her husband in the task of changing America.C) Outshine previous First Lady.D) Fully display her fine qualities.Passage TwoQuestions 62 to 66 are based on the following passage.When next year’s crop of high-school graduates arrive at Oxford University in the fall of 2009, they’ll be joined by a new face; Andrew Hamilton, the 55-year-old provost (教务长) of Yale, who’ll become Oxford’s vice-chancellor—a position equivalent to university presidentin America.Hamilton isn’t the only educator crossing the Atlantic. Schools in France, Egypt, Singapore, etc, have also recently made top-level hires from abroad. Higher education has become a big and competitive business nowadays, and like so many businesses, it’s gone global. Yet the talent flow isn’t universal. High-level personnel tend to head in onlyone direction: outward from America.The chief reason is that American schools don’t tend to seriously consider looking abroad. For example, when the board of the Universityof Colorado searched for a new president, it wanted a leader familiar with the state government, a major source of the university’s budget. “We didn’t do any global consideration,”says Patricia Hayes, the board’s chair. The board ultimately picked Bruce Benson, a 69-year-old Colorado businessman and political activist (活动家) who is likely to do well in the main task of modern university presidents: fund-raising. Fund-raising is a distinctively American thing, since U.S. schools rely heavily on donations. The fund-raising ability is largely a product of experience and necessity.Many European universities, meanwhile, are still mostly dependenton government funding. But government support has failed to keep pace with rising student number. The decline in government support hasmade funding-raising an increasing necessary ability among administrators and has hiring committees hungry for Americans.In the past few years, prominent schools around the world have joined the trend. In 2003, when Cambridge University appointed AlisonRichard, another former Yale provost, as its vice-chancellor, the universitypublicly stressed that in her previous job she had overseen “a major strengthening of Yale’s financial position.”Of course, fund-raising isn’t the only skill outsiders offer. The globalization of education means more universities will be seeking headswith international experience of some kind of promote international programs and attract a global student body. Foreigners can offer a fresh perspective on established practices.62. What is the current trend in higher education discussed in the passage?A) Institutions worldwide are hiring administrators from the U.S.B) A lot of political activists are being recruited as administrators.C) American universities are enrolling more international students.D) University presidents are paying more attention to funding-raising.63. What is the chief consideration of American universities when hiring top-level administrators?A) The political correctness. B) Their ability to raise funds.C) Their fame in academic circles. D) Their administrative experience.64. What do we learn about European universities from the passage?。

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

英语四级阅读题库含答案解析1.Passage Onest century, Global warming may or may not be the great environmental crisis of the 21’t –we won ’t do much about it. We will argue overbut regardless of whether it is or isnit and may even, as a nation, make some fairly solemn-sounding commitments to avoid it. But the more dramatic and meaningful these commitments seem, the less likely they are to be observed.Al Gore calls global warming an “inconvenient truth, ”as if merely recognizing it’t know enough tocould put us on a path to a solution.

The January fashion show, called Future Fashion , exemplified how far green design has come. Organized by the New York-based nonprofit Earth Pledge, t he show inspired many top designers t o work with sustainable fabrics for the first time. Several have since made pledges to include organic fabrics in their lines.The designers who undertake green fashion still face many challenges. Scott Hahn, cofounder with Gregory of Rogan and Loomstate, which uses all-organic cotton, says high-quality sustainable materials can still be tough to fine . “Most designers with existing labels are finding’re doingthere aren ’t comparable fabrics that can just replace what youand shat your customers are used to, ”he says. For example, organic cotton and non-organic cotton are virtually indistinguishable o nce woven into a dress. But some popular synthetics, like stretch nylon, still have few eco-friendly equivalents.Those who do make the switch are finding they have more support. Last year the influential trade show Designers &Agents stopped(企业家) who charging its participation fee for young greenentrepreneursattend its two springtime shows in Los Angeles and New York and gave special r ecognition to designers w hose collections a re at least 25% sustainable .

The differences result from weather p atterns.

The heaviestboth elements are also present as heavierraid falls first .As a result, storms that form over the Pacific deliver heavier water to California than to Utah.Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can construct a geographic t imeline. Each i nch of hair corresponds to about two months.Cerling ’s team collected t ap water samples f rom 600 cities and constructed a mop of the regional differences. T hey checked the accuracy of the map by testing 200 hair samples c ollected f rom 65 barber shops.They were able to accurately place the hair samples in broad regions roughly corresponding to the movement of raid systems.“It’s not good for pinpointing ( 精确定位),”Cerling said .“It’s good”for eliminating many possibilities.Todd Park, a local detective, said the method has helped him learn more about an unidentified woman whose skeleton w as found nearGreat Salt Lake.The woman was 5 feet tall. Police recovered 26 bones, a T-shirt and several strands of hair.When Park heard about the research, he gave the hair samples to the researchers. Chemical testing showed that over the two years before her death, she moved about every two months.She stayed in the Northwest, although the test could not be more specific than somewhere between eastern Oregon and western Wyoming.”Park said “But it narrows it way down “It’s still a substantial area,for me. ”62.

英语四级阅读理解练习题及答案解析
英语四级阅读理解练习题及答案解析英语四级阅读理解练习题原文If the salinity(含盐量) of ocean waters is analyzed, it is found to vary only slightly from place toplace.Nevertheless, some of these small changes are important. There are three basic processesthat cause a change in oceanic salinity. One of these is the subtraction of water from the oceanby means of evaporation--conversion of liquid water to water vapor. In this manner, thesalinity is increased, since the salts staybehind. If this is carried to the extreme, of course,white crystals of salt would be left behind.The opposite of evaporation is precipitation(降水), such as rain, by which water is added tothe ocean. Here the ocean is being diluted(稀释) so that the salinity is decreased. This mayoccur in areas of high rainfall or in coastal regions where rivers flow into the ocean. Thus salinitymay be increased by the subtraction of water by evaporation, or decreased by the additionof fresh water by precipitation or runoff(形成地表水部分的降水).Normally, in tropical regions where the sun is very strong, the ocean salinity is somewhathigher than it is in other parts of the world where there is not as much evaporation. Similarly,in coastal regions whererivers dilute the sea, salinity is somewhat lower than in other oceanicareas.A third process by which salinity may be altered is associated with the formation and meltingof sea ice. When seawater is frozen, the dissolved materials are left behind. In this manner,seawater directly beneath freshly formed sea ice has a higher salinity than it did before the iceappeared. Of course, when this ice melts, it will tend to decrease the salinity of the surroundingwater.In the Weddell Sea, off Antarctica, the densest water in the oceans is formed as a result of thisfreezingprocess, which increases the salinity of cold water. This heavy water sinks and is foundin the deeper portions of the oceans of the world.英语四级阅读理解练习题1.The best title of the passage can be “_____”.A.Typical Oceans and Their Respective FeaturesB.The Causes of the Changes in Salinity of Ocean WaterC.Different Oceans Have Different SalinityD.The Precipitation and Evaporation of Oceans2.Which of the following processes will increase salinity of ocean waters?A.Evaporation.B.

它是一个温泉疗养中心, 里面逼真地模拟了日本江户末年街道、小餐馆、商店的情景, 那些年日本尚未因外来力量的冲击而发生改变。
这个名为“江户温泉神话”的浴场是董事长中村勇夫多年的梦想。
中村勇夫惋惜战后日*化的美国化及其对东京的影响。
“过去我们告诉国外游客到京都去体味和享受古朴的日本, ”中村说:“如今他们可以来这里。
”在日本的黄金时代温泉浴行业有前景的想法已经得到映证。
现在人们甚至用一个专门的词——— iyashi-sangyo , 即治疗产业, 来表示这一行业。
该行业通过提供各种服务来缓解日本似乎无止尽的经济衰退引起的焦虑。
其中包括: 熏香、按摩和短期的田间劳作, 但这些都不及温泉受欢迎, 温泉的治疗效果已是久负盛名。
日本是火山群岛, 有三万多处然温泉和三千多处大多分布在乡间小旅馆里的温泉胜地。
中村建设中的这家浴场规模和排场都是史无前例的, 是一座位于东京市中心的具有乡村风情的庞大的浴室和主题公园。
另外还有两家温泉疗养中心正在建设中, 其中一家造价比中村浴场的四千六百万美元几乎高出三倍。
在一所大学研究温泉文化的教授松田忠德说, 在市中心快速矗立起的这些庞大的设施, 暗示人们对经济的焦虑“已经一触即发”, 而投资者们想从中渔利。
东京新的浴场和传统的澡堂大同小异。
在一般的澡堂, 客人花4 美元用普通的水洗刷一下, 午夜打烊时, 他们就得离开。
东京所有新建的浴场都要用抽自地下1 700 米深处的真正的矿物温泉水。
他们提供每次最低消费为20 美元的时间更长、更舒适的服务。
尽管这股建设热潮中存在风险, 但是在日本温泉浴行业似乎充满了商机: 现有的温泉浴场每年接待3 亿白天来访的客人。

英语四级考试阅读理解练习题(一)People become quite illogical when they try to decide what can be eaten and what cannot beeaten. If you lived in the Mediterranean, for instance, you would consider octopus a greatdelicacy. You would not be able to understand why some people find it repulsive. On theother hand, your stomach would turn at the idea of frying potatoes in animal fat -- the normallyaccepted practice in many northern countries. The sad truth is that most of us have beenbrought up to eat certain foods and we stick to them all our lives.No creature has received more praise and abuse than the common garden snail. Cooked inwine, snails are a great luxury in variousparts of the world. There are countless people who,ever since their early years, have learned to associate snails with food. My friend, Robert, livesin a country where snails are despised. As his flat is in a large town, he has no garden of hisown. For years he has been asking me to collectsnails from my garden and take them to him.The idea never appealed to me very much, but one day, after heavy shower, I happened to bewalking in my garden when I noticed a huge number of snails taking a stroll on some of myprize plants. Acting on a sudden impulse, I collected several dozen, put them in a paperbag,and took them to Robert. Robert was delighted to see me and equally pleased with my littlegift.

英语四级阅读理解习题附答案解析
英语四级阅读理解习题附答案解析Of all the components of a good night's sleep, dreams seem to be least within our control. Indreams, a window opens into a world where logic is suspended and dead people speak. Acentury ago,Freud formulated his revolutionary theory that dreams were the disguisedshadows of our unconscious desires and fears; by thelate 1970s, neurologists had switched tothinking of them as just"mental noise"-the random byproducts of the neural repair work thatgoes on during sleep. Now researchers suspect that dreams are part of the mind's emotionalthermostat, regulating moods whilethe brain is "off line." And one leading authority says thatthese intensely powerful mental events can be not only harnessed but actually brought underconscious control, to help us sleep andfeel better. "It's your dream," says RosalindCartwright, chair of psychologyat Chicago's Medical Center, "if you don't like it, change it."he link between dreams and emotions shows up among the patients in Cartwright's clinic. Mostpeople seem to have more bad dreams early in the night, progressing toward happier onesbeforeawakening, suggesting that they are working through negative feelings generatedduring the day. Because our conscious mind is occupied with dailylife we don't always thinkabout the emotionalsignificance of the day's events-until, it appears, we begin to dream.And this process need not be left to the unconscious. Cartwright believes one can exerciseconscious control over recurring bad dreams. As soon as you awaken, identify what isupsetting aboutthe dream. Visualizehow you would like it to end instead; the next time itoccurs, try to wake up just enough to control its course. With much practice people can learnto, literally, do it intheir sleep.At the end of the day, there's probably little reason to pay attention to our dreams at all unlessthey keep us from sleeping or "we wake up in panic," Cartwright says. Terrorism,economicuncertainties and general feelings of insecurity have increased people's anxiety. Thosesuffering from persistent nightmares should seek help from a therapist. For the rest of us,thebrain has its ways of working through bad feelings.Sleep-or rather dream-on it and you'll feelbetter in the morning.练习题：Choose correct answers to the question:1.By saying that “dreams are part of the mind's emotional thermostat," Lines 4-5,Para. 1 the researchers mean that _______.A.we can think logically in the dreams tooB.dreams can be brought under conscious controlC.dreams represent our unconscious desires and fearsD.dreams can help us keep our mood comparatively stable2.What did Cartwright find in her clinic?A.Most bad dreams were followed by happier ones.B.Divorced couples usually have more bad dreams.C.One’s dreaming process is related to his emotion.D.People having negative feelings dream more often.3.Cartwright believed with much practice，we can learn to _____.A.control what dreams to dreamB.sleep well without any dreamsC.wake up in time to stop the bad dreamsD.identify what is upsetting about the dreams4.The author points out that a person who has constant bad dreams should ______A.learn to control his dreamsB.consult a doctorC.sleep and dream on itD.get rid of anxiety first5.The author most probably thinks that controlling dreams is ______.A.a good practiceB.a new discoveryC.helpful for everyoneD.not essential for everyone1.[D] 词义理解题。

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 barrier tosubstance 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 in northern England, who led the study. "They also suggest thatattachment,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 nearly 4 , 000 teenagers inEngland, Ireland, Italy, Germany and the Netherlands. They were questioned about their use ofcannabis, 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 tomeet friends 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 protection againstdeveloping 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 32 percent.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.

大学生英语四级考试阅读理解试题及答案解析1The world has become a world of cities. With the present rate of urban growth(3. 8% in the Third World) , the majority of the population of the world will be living in cities by the year 2000. This will transform the rural-urban equation which has marked the history of mankind up to now and will call for new example and a great deal of innovation to face this phenomenon.This being so, one must accept the fact that for some years to come, no policy will be capable of stopping or reversing the present migratory trend from the rural areas to the cities in the Third World. In Africa, the urban population will reach 330 million people by the end of the century as against 150 million in 1995.The number of people living in shanty-towns (贫富窟) will inevitably increase in spite of the efforts to improve housing conditions.Africa alone needs to build 12 million housing units between now and the year 2000 to meet its most basic needs. In an ILO study, M. S. V. Sethuraman estimates that in 70 Third "World cities the proportion of people living in shanty-towns varies from 15% to 70% and that about US $ 116 billion is required to give minimum comfort to these people by the turn of the century—less than US $ 10 billion per year.The world population is growing at a rate of about 90 million people per year, with the Third World accounting for 80 million of them. The pressure on cities can only go on increasing. The urban population of the developing countries will exceed 2 billion people by the year 2000 and since the main reason for the high demographic (人口统计的) growth is poverty, the additional population will be mostly made of people of very limited means.21. If the urban population of the developing countries exceeds 2 billion people by the year 2000, the main problem the additional people will face is______.A. housingB. foodC. povertyD. limited land22. According to the passage, "about US $116 billion is required to give minimum comfort to these people by the turn of the century—less than US $ 10 billion per year. " Do you think which year was the article written by saying "less than $ 10 billion per year" by theturn of the century?A. 1985.B. 1990.C. 1988.D. 2000.23. The mankind should face the phenomenon that the world has become a world of cities with______.A. a lot of difficultiesB. efforts to improve housing conditionC. pressure of the basic needsD. new models and a great deal of transformation of ideas and methods24. In Africa, people in cities will be______by the end of the century.A. almost twice as much as in 1985B. doubled than that in 1985C. over twice as much as in 1985D. 300 million25. In spite of the efforts to improve housing condition, the number of people living in shanty-towns will increase because______.A. houses in shanty-towns are cheapB. shanty-towns could provide people with minimum comfortC. no policy will be capable of stopping or changing the present immigrant tendency from the rural areas to the cities in the Third WorldD. the Third Word population is growing at a rate of about 80 million people per year答案：21. C 22. C 23. D 24. C 25. C大学生英语四级考试阅读理解试题及答案解析2There are two factors which determine an individuals intelligence. The first is the sort of brain he is born with. Human brains differ considerably, some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual—the sort of environment in which he is reared. If an individual is handicapped envionmentally ,it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable. The importance of environment in determining an individuals intellingence can be demonstrated by the case history of the identical twins, Peter and Mark X. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old , their parents died, and they were placed in separate foster homes. Peter was reated by parents of low intelligence in an isolatedcommunity with poor educational pooprtunities.Mark was reared inthe home of well-to-do parents who had been to college. He was read to as a child , sent to good schools, and given every opportunity to be stimulated intellectually.This enviromental difference continued until the twins were in their late teens, when theywere giben tesets to measure their intelligence. Marks I.Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities , the twins , having identical brains,would have tested at roughly the same level.1.This selection can best be titled_________.a.Measuring Your Intelligenceb.Intelligence and Environmentc.The Case of Peter and Markd.How the brain Influences Intelligence2.The beststatement of the main idea of this passage is that _____. a.human brains differ considerablyb.the brain a person is born with is improtant in determining his intelligencec.environment is crucial in determining a persons intelligenced. persons having identical brains will have roughly the same intelligence3.According to the passage , the average I.Q.is _____.a.85b.100c.110d.1254.The case history of the twins appears to support the conclusion that _______. a.individual with identical brains seldom test at same level b.an individuals intelligence is determined only by his enviroment ck of opportunity blocks the growth of intelligence d.changes of enviromentproduce changes in the structure of the brain5.This passage suggests that an individual s I.Q.______. a.can be predicted at birthb.stays the same throuthout his lifec.can be increased by educationd.is determined by his childhood答案：bcbcc大学生英语四级考试阅读理解试题及答案解析3There are three kinds of goals: short-term,medium-range and long-term goals. Short-range goals are those that usually deal with current activities,which we can apply on a daily basis.Such goals can be achieved in a week or less,or two weeks,or possible months.It should be remembered that just as a building is no stronger than its foundation ,out long-term goals cannot amount to very munch without the achievement of solid short-term goals.Upon completing our short-term goals,we should date the occasion and then add new short-term goals that will build on those that have been completed. The intermediate goals bukld on the foundation of the short-range goals.They might deal with just one term of school or the entire school year,or they could even extend for several years.Any time you move a step at a time,you should never allow yourself to become discouraged or overwhelmed. As you complete each step,you will enforce the belief inyour ability to grow adn succeed.And as your list of completion dates grow,your motivation and desire will increase. Long-range goals may be related to our dreams of the future. They might cover five years or more. Life is not a static thing.We should never allow a long-term goal to limit us or our course of action. 1.Our long-term goals mean a lot______.A.if we complete our short-range goalsB.if we cannot reach solid short-term goalsC.if we write down the datesD.if we put forward some plans2.New short-term goals are bulid upon______.A.two yearsB.long-term goalsC.current activitiesD.the goals that have been completed3.When we complete each step of our goals ,______.A.we will win final successB.we are overwhelmedC.we should build up confidence of successD.we should strong desire for setting new goals 4.Once our goals are drawn up,_______.A.we should stick to them until we complete themB.we may change our goals as we have new ideas and opportunitiesC.we had better wait for the exciting news of successD.we have made great decision5.It is implied but not stated in the passage that ______.A.those who habe long-term goals will succeedB.writing down the dates may discourage youC.the goal is only a guide for us to reach our desinationD.every should have a goal答案：adcbc大学生英语四级考试阅读理解试题及答案解析4Today ,as in every other day of the year ,more than 3000 U.S. adlescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime,it can be expected that of these 3000 about 23 will be murdered,30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweithts all other factors, whether voluntary or involuntary, as a cause of death. Since the late 1970s, when daily smoking among high school seniors reached 30 precent , smoking rates among youth have declined . While the decline is impressive ,several important issues must be raised. First, in the past several years,smoking rates among youth have declined very little. Second,in the late 1970s ,smoking among male high school seniors exceeded that among female by nearly 10 percent . The statistic is reversing.Third ,several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent . Finally,thouth significant declines in adolescent smoking have occurred in the past decade,no definite reasons for the decline exist. Within this context,the Naional Cancer Instiute (NCI) began its current effort to determine the most effecive measures to reduce smoking levesl among youth.1.According to the author, the deaths among youth are mainly caused by _____.a.traffic accidentsb.smoking-related deseasec.murderd.all of these2.Every day there are over_____high school strdents who will become regular smoker.a.75b.23c.30d.30003.By "dropout" the author means______.a.students who failed the examinationb.students who left schoolc.students who lost their wayd.students who were driven out of school4.The reason for declining adolescent smoking is that ________.a.NCI has taken effective measuresb.smoking is prevented among high school seniorsc.there are many smokers who have died of cancerd.none of these5.What is implied but not stated by the author is that ________.a.smoking rates among youth have declined very littleb.there are now more female than male smokers among high school seniorsc.high smoking rates are due to the incease in wealthd.smoking at high school are from low socio-economic backgrounds答案：bdbdb【大学生英语四级考试阅读理解试题及答案解析】。

The level of S 1 PR2 is lower,the MS is less severe.D、The level of S 1 PR2 is lower,the MS is more severe.59.What role does SlPR2 play in helping the permeabilityofblood.brain barrier?A.It can make blood.brain barrier impermeable.B.It can make blood—brain barrier less permeable.C.It can make blood—brain barrier permeable.D.It can make blood—brain barrier more permeable.60.What can we infer from the whole passage?A.Four times more women than men are currently diagnosed with MS.B. The level of S 1 PR2 was positively correlated with theseverity of MS.C.The reason why MS affects more women than men is unknown.D.Multiple sclerosis discovery may explain gender gap.Questions 61 to 65 are based on e web search—-which scours only the latest updates to services like Twitter—is currently generating quite a buzz because it can provide a glimpse of what people around the world are thinking or doing at any given moment.Interest in this kind of search is so great that，according to recent leaks，Google is considering buying Twitter.The latest research from the interact search giant，though，suggests that real—time results could be even more powerful—they may reveal the future as well as the present.Google researchers Hyunyoung Choi and Hal Varian combined data from Google Trends on the popularity of different search terms with models used by economists to predict trends in areas such as travel and home sales.The result?Better forecasts in A.most every case.It works because searches reveal something about people’sintentions.Google has demonstrated before that search data canpredict flu outbreaks，and last week World Bank economist Erik Feyen said he could cut errors in a model that forecasts lending to the private sector by 15%using Google search data.But real-time results could have even more predictive power：knowing what people are actually doing，not just thinking，at a particular instant gives a strong hint of the future consequences. Johan Bollen of Los A.amos NationA. Laboratory and A.berto Pepe of the University of California，Los Angeles，applied a mood rating system to the text from over 10，000 Future Me emails sent in to gauge people’s hopes，fears and predictions for the future.They found that emails directed at to were significantly more depressed in tone than messages aimed at the subsequent six years.Could they have predicted the world’s current economic slump?Without more data，that is no more than an intriguingpossibility.So Bollen plans to look at more Future Me emails，as well as Twitter messages，to search for mood swings that foreshadow other economic changes.If he finds any such links.the sanle sources might be used to try and predict future economic fluctuations.So will our online footsteps become a central part of economic forecasting?We’11 have to wait and see——0r perhaps do a quick web search.61.What is real-time web search.like Twitter?A.It tells us what people did in past days.B.It generates quite a buzz in recent days.C.It provides latest news about everything.D.It informs what people do in the future.62.What is the result of research established by Google researchers Hyunyoung Choi and Hal Varian?A.They gain nothing special from the combination of data and models.B. 11ley indeed reveal something about people’s intentions in such areas.C. They find that the future trends cannot be predicted from the research.D.They totally understand the future trends of these areas from research.63.What can we infer from Para.5?A. It is possible for researchers to get some hints from the Future Me emails.B. There is no relationship between the depression and economic slump.C.There is a potential relationship between depression and economic slump.D.The Future Me emails may indicate people’s reaction about future prediction.64.What’s the meaning of“Without more data,that is no more than an intriguing possibilit y.”?A.

英语四级阅读理解精选练习及参考答案
英语四级阅读理解精选练习及参考答案四级阅读理解精选练习一：Trees should only be pruned when there is a good and clear reason for doing so and , fortunately,the number of such reasons is small. Pruning involves the cutting away of obergrown and unwanted branches, and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the tree to grow in its own way.First, pruning may be done to make sure that trees have a desired shape or size. The object may be to get a tree of the right height, and at the same time to help the growth of small side branches which will thicken its appearance or give it a special shape. Secondly, pruning may be done to make the tree healthier. You may cut diseaed or dead wood, or branches that are rubbing against each other and thus cause wounds. The health of a tree may be encouraged by removing branches that are blocking up the centre and so preventing the free movement of air.One result of pruning is that an open wound is left on the tree and this provides an easy entry for disease, but itis a wound that will heal. Often there is a race between the healing and the desease as to whether the tree will live or die, so that there is a period when the tree is at risk. It should be the aim of every gardener to reduce which has been pruned smooth and clean, for healing will be slowed down by roughness. You should allow the cut surface to dry for a few hurs and then paint it with oneof the substances available from garden shops produced especially for this purpose. Pruning is usually without interference from the leaves and also it is very unlikely that the cuts yu make will bleed. If this does happen,it is, of course,impossible to paint them properly.1.Pruning should be done to ______.a.make the tree grow tallerb.improve the shape of the treec.get rid of the small branchesd.make the small branches thicker2.Trees become unhealthy if the gardener ______.a.allows too many branches to grow in the middleb.does not protect them from windc.forces them to grow too quicklyd.damages some of the small side branches3.Why is a special substance painted on the tree?a.To make a wound smoothb.To prevent disease entering a woundc.To cover a rough surfaced.To help a wound to dry4.A good gardener prunes a tree______.a.at intervals throughout the yearb.as quickly as possiblec.occasionally when necessaryd.regular every winter5.What was the authors purpose when writing this passage?a.To give pratical instruction for pruning a tree.b.To give a general description of pruningc.To explain how trees develop diseasesd.To discuss different methods of pruning.答案：babca四级阅读理解精选练习二：On Thursday afternoon Mrs. Carke, dressed for going out, took her handbag with her money and her key in it, pulled the door behind her to lock it and went to the over 60s Club. She always went there on Thursdays. It was a nice outing for an old woman who lived alone.At six oclock she cane home, let herself in and at once smelt cigarette smoke. Cigarette smoke in her house? How? How? Had someone got in? She checked the back door and the windows. All were locked or fastened, as usual. There was no sign of forced entry.Over a cup of tea she wondered whether someone might have a key that fitted her front door-"a master key"perhaps. So she stayed at home the following Thursday. Nothing happened. Was anyone watching her movements?On the Thursday after that she went out at her usual time,dressed as usual, but she didnt go to the club. Instead she took a short cut home again, letting herself in through her garden and the back door. She settled down to wait.It was just after four oclock when the front door bell rang.Mrs. Clarke was making a cup of tea at the time. The bell rang again, and then she heard her letter-box being pushed open. With the kettle of boiling water in her hand, she moved quietly towards the front door.

Passage 1:Fishing in BritainFishing is the third most popular participation sport in Britain as a whole and the most popular participation sport in many parts of the country, notably Wales, the Borders and south-west England. Anglers in Britain spent over ￡2 billion on their sport in 1996, and since then this amount has continued to increase.Anglers can choose from a range of freshwater or saltwater locations. For new anglers, some local fishing clubs provide an excellent way of learning about the sport. They operate a no-kill policy, which means that all fish caught are returned unharmed to the water. Most clubs... rivers. Larger still (and even more expensive!) are the lakes, which are often found on country estates.In addition to the financial cost, fishing requires patience and determination. You are unlikely to catch fish immediately and will probably spend hours waiting. However, many anglers find this part of the experience enjoyable and relaxing. They see fishing as an escape from the stresses of everyday life.1. Fishing is the most popular participation sport inA) WalesB) the BordersC) south-west EnglandD) the whole of Britain答案: D) the whole of Britain解析: 根据第一句话可得出答案。

英语四级阅读理解练习题及解析【阅读练习】What is it about Americans and food? We love to eat,but we feel 1 about it afterward. We say we want only the bes t, but we strangely enjoy junkfood. We’re 2 with health an d weight loss but face an unprecedented epidemic of obes ity(肥胖). Perhaps the 3 to this ambivalence(矛盾情结) lies in our history. The first Europeans cameto this con tinent searching for new spices but went in vain. The first cash crop(经济作物)wasn’t eaten but smoked. Then there was Prohibition, i ntended to prohibit drinking butactually encouraging more 4 ways of doing it.The immigrant experience, too, has been one of inharmon y. Do as Romans do meanseating what “real Americans” e at, but our nation’s food has come to be 5 by imports—piz za,say, or hot dogs. And some of the country’s most treas ured cooking comes from people whoarrived here in shack les.Perhaps it should come as no surprise then that food has been a medium for the nation’sdefining struggles, whether at the Boston Tea Party or the sit?ins at southern lunch c ounters.It is integral to our concepts of health and even m orality whether one refrains from alcohol forreligious reaso ns or evades meat for political 6But strong opinions have not brought 7 . Americans are a mbivalent about what they putin their mouths. We have b ecome 8 of our foods, especially as we learn more about what theycontain.The 9 in food is still prosperous in the American conscious ness. It’s no coincidence, then,that the first Thanksgiving holds the American imagination in such bondage(束缚). It’s whatwe eat—and how we 10 it with friends, famil y, and strangers—that help define America as acommunity today.A. answer I. creativeB. result J. beliefC. share K. suspiciousD. guilty L. certaintyE. constant M. obsessedF. defined N. identifyG. vanish O. idealsH. adapted【答案及详解】1. D feel是一个系动词，可以判断此处应填入一个形容词，通过上下文意思，以及后面介词about, 可以确定选项为D项guilty, 短语feel guilty about sth. “对……感到有愧”。
全句的意思为“我们很爱吃，但是往往在吃完之后又有负罪感”。
2.M be obsessed with 为固定搭配，原意为“被……附上/缠住/迷住心窍”，放在本句表示“十分重视”。
全句的意思为“我们很关心健康和减肥，但肥胖却又空前地在蔓延”。
3. A 本句缺一个名词作主语，并且根据和介词to的搭配，可以推断出正确选项answer.4. I本句根据more和ways可以判断出需要填入一个形容词构成比较级，根据上下文，表示“旨在禁止酗酒的禁酒令，却激发了更多新奇的方法来酗酒”，可以确定I为正确选项。
5. F 本题较难。
根据be 和by 确定应填入一个过去分词。
再根据上下文，上文表示“应该吃典型的美国人吃的食物”，下文通过 but 转折，表示实际上“美国的食物已经被诸如比萨和热狗这样的舶来品所诠释了”，因此可以确定F为正确选项。
6.B政治结果，可根据宗教原因religious reasons来推断此处填政治结果。
7. L由于横线后面没有宾语，可以确定不是形成bring 的短语，这样本句所缺的为一名词，做bring的宾语。
根据下文解释，“美国人对他们所吃的食物的态度是矛盾的”，可以推出本句意义为“坚定的观点也不是确定不变的”。
因此可以确定L为正确选项。
8. K系动词become后应填入一个形容词，和后面介词of形成短语be/become suspicious of“对……感到怀疑”。
9. J本句缺一个名词作主语，并且根据和介词in的搭配，可以推断出正确选项belief，(have)belief in sth.“ 相信……”。
10. C本句是一般现在时，缺一个动词，且和with 搭配，确定选项为share, share sth. withsb., “与某人分享某事”。
