A study of art history might be a good way to learnmore about a culture than is possible to learn ingeneral history classes. Most typical history coursesconcentrate on politics, economics, and war. But arthistory focuses on much more than this because artreflects not only the political values of a people, butalso religious beliefs, emotions, and psychology. Inaddition, information about the daily activities of ourancestors—or of people very different from our own—can be provided by art. In short, artexpresses the essential qualities of a time and a place, and a study of it clearly offer us adeeper understanding than can be found in most history books.In history books, objective information about the political life of a country is presented; that is,facts about politics are given, but opinions are not expressed. Art, on the other hand, issubjective: it reflects emotions and opinions. The great Spanish painter Francisco Goya wasperhaps the first truly “political” artist. In his well-known painting The Third of May 1808, hecriticized the Spanish government for its misuse of power overpeople. Over a hundred yearslater, symbolic images were used in Pablo Picasso’s Guernica to express the horror of war.Meanwhile, on another continent, the powerful paintings of Diego Rivera, Jose Clemente Orozco,and David Alfaro Siqueiros—as well as the works of Alfredo Ramos Martines—depicted theseMexican artists’ deep anger and sadness about social problems.In the same way, art can reflect a culture’s religious beliefs. For hundreds of years in Europe,religious art was almost the only type of art that existed. Churches and other religious buildingswere filled with paintings that depicted people and stories from the Bible. Although mostpeople couldn’t read, they could still understand biblical stories in the pictures on church walls.By contrast, one of the main characteristics of art in the Middle East was (and still is) itsabsence of human and animal images. This reflects the Islamic belief that statues are unholy.1.More can be learned about a culture from a study of art history than general history becauseart history__.A.show us the religious and emotions of a people in addition to political values.B.provide us with information about the daily activities of people in the past.C.give us an insight into the essential qualities of a time and a place.D.all of the above.2.Art is subjective in that__.A.a personal and emotional view of history is presented through it.B.it can easily rouse our anger or sadness about social problems.C.it will find a ready echo in our hearts.D.both B and C.3.Which of the following statements is true according to the passage?A.Unlike Francisco Goya, Pablo and several Mexican artists expressed their political opinions intheir paintings.B.History books often reveal the compilers’ political views.C.Religious art remained in Europe for centuries the only type of art because most peopleregarded the Bible as the Holy Book.D.All the above mentioned.4.The passage is mainly discussing__.A.the difference between general history and art history.B.The making of art history.C.What can we learn from art.D.The influence of artists on art history.5.In may be concluded from this passage that__.A.Islamic artists have had to create architectural decorations with images of flowers orgeometric forms.B.History teachers are more objective than general history.C.It is more difficult to study art history than general history.D.People and stories from the Bible were painted on churches and other buildings in order topopularize the Bible.答案：DDDCA词汇讲解1. misuse 误用,滥用He felt misused by the company.他觉得公司对他使用不当。

专业英语四级（阅读）模拟试卷26(题后含答案及解析) 题型有： 5. READING COMPREHENSIONPART V READING COMPREHENSION (25 MIN)Directions: In this section there are four passages followed by questions or unfinished statements, each with four suggested answers marked A, B, C and D. Choose the one that you think is the best answer.Every person plans to run off to some tropical isle, but few do. Real life, family, work, and monetary limitations get in the way. Ian Fleming let none of these considerations stop him. After the war, Fleming set down his schedule. The first week of January saw him leave England and travel to Jamaica. The first week of March saw his return. He accepted his job at Kemsley Newspapers without compromise—this portion of the year would be set aside for Jamaica or he would look elsewhere for employment. For 6 years Fleming traveled each winter to Jamaica, lounging in paradise, romancing women, chasing the sunset, but it was not until he faced the pressure of a married woman who was pregnant with his child did Fleming start the writer’s journey which would change his life and popular culture forever. As Fleming waited in Jamaica for Anne’s divorce to become final, he wrote the first draft of a novel, Casino Royale. Fleming’s career as a writer deserves more examination than can be offered here, but suffice it to say, over the next 12 years, Ian Fleming transformed his elite existence, his arrogance, his style, and his acid wit into some of the greatest thrillers ever written. Fleming incurred the respect of authors as diverse as Raymond Chandler, Kingsley Amis, and Edith Sitwell. His fans included John, Jackie, and Bobby Kennedy, and his social circle included Prime Minister Anthony Eden, Evelyn Waugh, and Somerset Maugham. Fleming filled out the 12 years of Bond with great adventure journalism. Even in stories which had little action or pay off, such as his short non-fiction book, The Diamond Smugglers, the “Fleming-flair”ensured exciting reading. He wrote the “Atticus”column for The Sunday Times, proving a wonderful conduit for inside intelligence information, and clever rebukes. Regardless of book sales or family obligations, Fleming managed to live the life he wanted. As the years passed, his passion for golfing increased so he took more time with it. Fleming’s long-term fascination with America grew, so he traveled there more often. Ian Fleming’s full life caught up with him through his heart. It may be that years of drinking and smoking took their toll, or that the butter-rich cooking Fleming loved was the culprit. Or maybe it was just genetics. Whatever the cause, Fleming’s health declined in the late 1950s. This plus anxieties in the marriage increased Fleming’s depression. With the success of Bond, the world came knocking at Fleming’s door, and he had a harder time shutting those out that he did not want in his life. Nonetheless, Fleming fought the loosing battle of his weakening heart by throwing more fuel on the fire. He continued to drink and smoke,making some excuses but not many. He wrote books he wanted to read, and traveled the world with style and authority. By this time, Fleming had already earned his own fortune, created his own identity, and ruled his own literary empire.1．According to the second paragraph, Fleming accepted the job offered by Kemsley NewspapersA．and had to give up his yearly holiday plan to Jamaica.B．because he was offered to work in Jamaica every winter.C．so that he wouldn’t have to look for employment elsewhere.D．on condition that he took two months off to Jamaica every year.正确答案：D解析：第2段最后一句破折号后的内容是Fleming接受Kemsley Newspapers 的工作的条件，破折号后的内容就是这个条件，D中的on condition that也表示基于某种条件去做一件事，D是对破折号后的内容的近义改写，因此为本题答案。

英语四级长篇阅读模拟练习英语四级长篇阅读模拟练习：A: What do we mean by being talented or gifted? The most obvious way is to look at the work someone does and if they are capable of significant success, label them as talented. The purely quantitative route —percentage definition— looks not at individuals, but at simple percentages, such as the top five percent of the population, and labels them — by definition — as gifted. This definition has fallen from favor, eclipsed by the advent of IQ tests, favored by luminaries such as Professor Hans Eysenck, where a series of written or verbal tests of general intelligence leads to a score of intelligence.B: The IQ test has been eclipsed in turn. Most people studying intelligence and creativity in the new millennium now prefer a broader definition, using a multifaceted approach where talents in many areas are recognized rather than purely concentrating on academic achievement. If we are therefore assuming that talented, creative or gifted individuals may need to be assessed across a range of abilities, does this mean intelligence can run in families as genetic or inherited tendency? Mental dysfunction — such as schizophrenia — can, so is an efficient mental capacity passed on from parent to child?C: Animal experiments throw some light on this question, and on the whole area of whether it is genetics, the environment or a combinationof the two that allows for intelligence and creative ability. Different strains of rats show great differences in intelligence or rat reasoning. If these are brought up in normal conditions and then run through a maze to reach a food goal, the bright-strain make far fewer wrong turns that the dull-ones. But if the environment is made dull and boring the number of errors becomes equal. Return the rats to an exciting maze and the discrepancy returns as before — but is much smaller. In other words, a dull rat in a stimulating environment will almost do as well as bright rat who is bored in a normal one. This principle applies to humans too — someone may be born with innate intelligence, but their environment probably has the final say over whether they become creative or even a genius.D: Evidence now exists that most young children, if given enough opportunities and encouragement, are able to achieve significant and sustainable levels of academic or sporting prowess. Bright or creative children are often physically very active at the same time, and so many receive more parental attention as a result — almost by default — in order to ensure their safety. They may also talk earlier, and this, in turn, breeds parental interest. This can sometimes cause problems with other siblings who may feel jealous even though they themselves may be bright. Their creative talents may be undervalued and so never come to fruition. Two themes seem to run through famously creative families as a result. The first is that the parents were able to identify the talents of each child, and nurture and encourage these accordingly but in an even handed manner. Individual differences were encouraged, and friendly sibling rivalry was not seen as particular problem. If the father is, say, a famous actor, there is no undue pressure for his children to follow himonto the boards, but instead their chosen interests are encouraged. There need not even by any obvious talent in such a family since there always needs to be someone who sets the family career in motion, as in the case of the Sheen acting dynasty.E: Martin Sheen was the seventh of ten children born to a Spanish immigrant father and an Irish mother. Despite intense parental disapproval he turned his back on entrance exams to university and borrowed cash from a local priest to start a fledgling acting career. His acting successes in films such as Badlands and Apocalypse Now made him one of the most highly-regarded actors of the 1970s. Three sons — Emilio Estevez, Ramon Estevez and Charlie Sheen — have followed him into the profession as a consequence of being inspired by his motivation and enthusiasm.F: A stream seems to run through creative families. Such children are not necessarily smothered with love by their parents. They feel loved and wanted, and are secure in their home, but are often more surrounded by an atmosphere of work and where following a calling appears to be important. They may see from their parents that it takes time and dedication to be master of a craft, and so are in less of a hurry to achieve for themselves once they start to work.G: The generation of creativity is complex: it is a mixture of genetics, the environment, parental teaching and luck that determines how successful or talented family members are. This last point — luck — is often not mentioned where talent is concerned but plays an undoubted part. Mozart, considered by many to be the finest composer of all time, was lucky to be living in an age that encouraged the writing of music. He was broughtup surrounded by it, his father was a musician who encouraged him to the point of giving up his job to promote his child genius. Mozart himself simply wanted to create the finest music ever written but did not necessarily view himself as a genius — he could write sublime music at will, and so often preferred to lead a hedonistic lifestyle that he found more exciting than writing music to order.H: Albert Einstein and Bill Gates are two more examples of people whose talents have blossomed by virtue of the times they were living in. Einstein was a solitary, somewhat slow child who had affection at home but whose phenomenal intelligence emerged without any obvious parental input. This may have been partly due to the fact that at the start of the 20th century a lot of the Newtonian laws of physics were being questioned, leaving a fertile ground for ideas such as his to be developed. Bill Gates may have had the creative vision to develop Microsoft, but without the new computer age dawning at the same time he may never have achieved the position on the world stage he now occupies.1. We can label someone who are capable of significant success as talented.2. Most people studying intelligence and creativity in the new millennium now prefer a broader definition.3. Animal experiments are contributed to whether it is genetics, the environment or a combination of the two that allows for intelligence and creative ability.4. Bright or creative children are often physically very active at the same time.5. Children in creative families feel loved and wanted, and are secure in their home.6. The generation of creativity is not simple.7. Bill Gates is an example of people whose talents have blossomed by virtue of the times they were living in.8. Evidence shows that bright or creative children are often physically very active and thus receive more parentalattention to ensure their safety.9. Luck is often not mentioned but an undoubted part of a person how creative or talented.10. Albert Einsteins and Bill Gates significant success may be due to thetimes they were living in.1. A2. B3.

FallingBehindA Teachers in the United States earn less relative tonational income than their counterparts in many industrialized countries, yet they spend far more hours in front of the classroom, according to a major newinternational study.B The salary differentials are part of apattern of relatively low public investment in education in the United States compared with other member nationsof the Organization for Economic Cooperation and Development, a group in Paris that compiled thereport. Total government spending on educational institutions in the United Statesslipped to 4.8 percent of gross domestic product in 1998, falling under theinternational average — 5 percent — for the first time.C “The whole economy has grown faster thanthe education system,”Andreas Schleicher, one of the reports authors,explained. “The economy has done very well, but teachers have not fullybenefit.” The report, due out today, is the sixth on education published since1991 by the organization of 30 nations, founded in 1960, and now covering muchof Europe, North America, Japan, South Korea, Australia and New Zealand.D In addition to the teacher pay gap, thereport shows the other countries have begun to catch up with the United Statesin higher education: college enrollment has grown by 20 percent since 1995across the group, with one in four young people now earning degrees. For thefirst time, the United States college graduation rate, now at 33percent, is not the worldshighest. Finland,the Netherlands, New Zealand and Britain have surpassed it.E The United States is also producingfewer mathematics and science graduates than most of the other member states.And, the report says, a college degree produces a greater boost in income herewhile the lack of a high school diploma imposes a bigger income penalty. “The number of graduates is increasing, but that stimulates even more of a demand —there is no end in sight,” Mr. Schleicher said. “The demand for skill, clearly,is growing faster than the supply that is coming from schools and colleges.”F The report lists the salary for a highschool teacher in the United Stateswith 15 years experience as $36,219, above the international average of $31,887but behind seven other countries and less than 60 percent of Switzerlands$62,052. Because teachers in the Unites States have a heavier classroom load —teaching almost a third more hours than their counterparts abroad — theirsalary per hour of actual teaching is $35, less than the international averageof $41 (Denmark, Spain and Germany pay more than $50 per teaching hour, SouthKorea $77). In 1994, such a veteran teacher in the United States earned 1.2 times theaverage per capita income whereas in 1999 the salary was just under thenational average. Only the Czech Republic, Hungary,Iceland and Norway pay their teachers less relative tonational income; in South Korea, teachers theactual teaching salary earn 2.5 times the nationalaverage. Teacher pay accounts for 56 percent of what the United Statesspends on education, well below the 67 percent average among the group ofcountries.G The new data come as the United Statesfaces a shortage of two million teachers over the next decade, with questions oftraining, professionalism and salaries being debated by politicians local andnational. Joost Yff, an international expert at the American Association ofColleges of Teacher Education, said training for teachers is comparable amongmost of the nations in the study, and that they are all dealing with similarissues of raising standards and increasing professionalism.H Though the United States lags behind in scores on standardized tests in science and mathematics, students here get more instruction in those subjects, the report shows. The average 14-year-oldAmerican spent 295 hours in math and science classes in 1999, far more than the229 international average; only Austria(370 hours), Mexico (367)and New Zealand(320) have more instruction in those subjects. Middle-schoolers here spend less time thantheir international counterparts studying foreign languages and technology, butfar more hours working on physical education and vocational skills. High schoolstudents in the United Statesare far more likely to have part-time jobs: 64 percent of Americans ages 15 to19 worked while in school, compared with an international average of 31 percent(only Canada and the Netherlands, with 69 percent, and Denmark,with 75 percent, were higher).I One place the United States spends more money is on special services for the disabled and the poor. More than one infour children here are in programs based on income — only five other countriesserve even 1 in 10— and nearly 6 percent get additional resources based on physical or mental handicaps, twice or three times the rate in other countries.J The report shows a continuing shift inwhich the United Statesis losing its status as the most highly educated among the nations. The UnitedStates has the highest level of high school graduates ages 55 to 64, but fallsto fifth, behind Norway, Japan, South Korea, the Czech Republic andSwitzerland, among ages 25 to 34. Among college graduates, it leads in theolder generation but is third behind Canada and Japan in the younger cohort (一群). While the portion of Americans with high schooldiplomas remains at 88 percent across age groups, the average age among membercountries is rising. It has gone from 58 percent of those ages 45 to 54, to 66percent of those ages 35 to 44 and 72 percent of those ages 25 to 34. A higherpercentage of young people in Norway,Japan, South Korea, the CzechRepublic and Switzerland have degrees than in the United States.K “The U.S. has led the development incollege education and making education sort of accessible for everyone,” Mr.Schleicher said. “Its now becoming the norm.”1. Compared with their counterparts in many industrialized countries, the U.S. teachers work longer.2. The U.S. government spent 4.8% of its GDP on education in 1998.3. From the passage we learn about Finland surpassesthe U.S.in college graduation rate.4. When the number of graduates in the U.S.increases, the demand for them is rising.5. The new study shows that the actual teaching salary per hour in the U.S. is $35.6. In the report, the U.S.students study of science and mathematics get most instruction in those subjects in the OECD.7. Compared with those in other OECD countries, high school students in the U.S. spend more time in in physical education and vocational skills.8. It is for the special services for thedisabled and the poor that the United States pays more money than other OECD countries.9. Those who have high school diplomas in the U. S. account for 88percent ofthe Americans of all ages.10. According toMr. Schleicher, the U.S.is becoming the norm in making education accessible for everyone and collegeeducation.1.A2.B3.D4.E5.F6.H7.H8.I9.J10.K。

（完整版）大学英语专业四级阅读理解模拟试题（含答案）（09）PART V READING COMPREHENSION [25 MIN]In this section there are four passages followed by questions or unfinished statements, each with four suggested answers marked A, B, C and D. Choose the one that you think is the best answer.TEXT AAt some time in your life you may have a strong desire to do something strange or terrible. However, chances are that you don’t act on your impulse, but let it pass inst ead. You know that to commit the action is wrong in some way and that other people will not accept your behavior.Perhaps the most interesting thing about the phenomenon of taboo behavior is how it can change over the years within the same society, how certain behavior and attitudes once considered taboo can become perfectly acceptable and natural at another point in time. Topics such as death, for example, were once considered so upsetting and unpleasant that it was a taboo to even talk about them. Now with the publication of important books such as On Death and Dying and Learning to Say Goodbye, people have become more aware of the importance of expressing feelings about death and, as a result, are more willing to talk about this taboo subject.One of the newest taboos in American society is the topic of fat. Unlike many other taboos, fat is topic that Americans talk about constantly. It’s not taboo to talk about fat; it’s taboo to be fat. The “in” look is thin, not fat. In the work world, most companies prefer youthful-looking, trim executives to sell theirimage as well as their products to the public. The thin look is associated with youth, vigor, and success. The fat person, on the other hand, is thought of as lazy and lacking in energy, self-discipline, and self-respect. In an image-conscious society like the U.S., thin is “in”, fat is “out”.I t’s not surprising, then, that millions of Americans have become obsessed with staying slim and “in shape”. The pursuit of a youthful physical appearance is not, however, the sole reason for America’s fascination with diet and exercise. Recent research has shown the critical importance of diet and exercise for personal health. As in most technologically developed nations, the life-style of North Americans has changed dramatically during the course of the last century. Modern machines do all the physical labor that people were once forced to do by hand. Cars and buses transport us quickly from point to point. As a result of inactivity and disuse, people’s bodies can easily become weak and vulnerable to disease. In an effort to avoid such a fate, millions of Americans are spending more of their time exercising.1.From the passage we can infer taboo is__.A.a strong desire to do something strange or terrible.B.a crime committed on impulse.C.behavior considered unacceptable in society’s eyes.D.an unfavorable impression left on other people.2.Based on the ideas presented in the passage we can conclude “being fat” __ in American society.A.will always remain a taboo.B.is not considered a taboo by most people.C.has long been a taboo.D.may no longer be a taboo some day.3.The topic of fat is __ many other taboo subjects.A.the same asB.different fromC.more popular thanD.less often talked about than.4.In the U.S., thin is “in”, fat is “out”, this means__.A.thin is “inside”, fat is “outside”.B.thin is “diligent”, fat is “lazy”.C.thin is “youthful”, fat is “spiritless”.D.thin is “fashionable”, fat is “unfashionable”.5.Apart from this new understanding of the correlation between health and exercise, the main reason thepassage gives for why so many Americans are exercising regularly is__.A.their changed life-style.B.their eagerness to stay thin and youthful.C.their appreciation of the importance of exercise.D.the encouragement they have received from their companies.TEXT BThe discovery of the Antarctic not only proved one of the most interesting of all geographical adventures, but created what might be called “the heroic age of Antarctic exploration”. By their tremendous heroism, men such as Shakleton, Scott, and Amundsen caused a new continent to emerge from the shadows, and yet that heroic age, little more than a century old, is already passing. Modern science and inventions are revolutionizing the endurance, future journeys into these icy wastes will probably depend on motor vehicles equipped with caterpillar traction rather than on the dogs that earlier discoverers found so invaluable and hardly comparable.Few realize that this Antarctic continent is almost equal in size to South America, and enormous field of work awaits geographers and prospectors. The coasts of this continent remain to be accurately charted, and the maping of the whole of the interior presents a formidable task to the cartographers who undertake the work. Once their labors are completed, it will be possible to prospect the vast natural resources which scientists believe will furnish one of the largest treasure hoards of metals and minerals the world has yet known, and almost inexhaustible sources of copper, coal, uranium, and many other ores will become available to man. Such discoveries will usher in an era of practical exploitation of the Antarctic wastes.The polar darkness which hides this continent for the six winter months will be defeated by huge batteries of light, and make possible the establishing of air-fields for the future inter-continental air services by making these areas as light as day. Present flying routes will be completely changed, for the Antarctic refueling bases will make flights from Australia to South America comparatively easy over the 5,000 miles journey.The climate is not likely to offer an insuperable problem, for the explorer Admiral Byrd has shown that the climate is possible even for men completely untrained for expeditions into those frozen wastes. Some of his parties were men who had never seen snow before, and yet he records that they survived the rigors of the Antarctic climate comfortably, so that, provided that the appropriate installations are made, we may assume that human beings from all countries could live there safely. Byrd even affirms that it is probably the most healthy climate in the world, for the intense cold of thousands of years has sterilize this continent, and rendered it absolutely germfree, with the consequences thatordinary and extraordinary sickness and diseases from which man suffers in other zones with different climates are here utterly unknown. There exist no problems of conservation and preservation of food supplies, for the latter keep indefinitely without any signs of deterioration; it may even be that later generations will come to regard the Antarctic as the natural storehouse for the whole world.Plans are already on foot to set up permanent bases on the shores of this continent, and what so few years ago was regarded as a “dead continent” now promises to be a most active center of human life and endeavor.6.When did man begin to explore the AntarcticA.About 100years ago.B.In this century.C.At the beginning of the 19th century.D.In 1798.7.What must the explorers be, even though they have modern equipment and techniquesA.Brave and toughB.Stubborn and arrogant.C.Well-liked and humorous.D.Stout and smart.8.The most healthy climate in the world is___.A.in South America.B.in the Arctic Region.C.in the Antarctic Continent.D.in the Atlantic Ocean.9.What kind of metals and minerals can we find in the AntarcticA.Magnetite, coal and ores.B.Copper, coal and uranium.C.Silver, natural gas and uranium.D.Aluminum, copper and natural gas.10.What is planned for the continentA.Building dams along the coasts.B.Setting up several summer resorts along the coasts.C.Mapping the coast and whole territory.D.Setting up permanent bases on the coasts.TEXT CWithout regular supplies of some hormones our capacity to behave would be seriously impaired; without others we would soon die. Tiny amounts of some hormones can modify moods and actions, our inclination to eat or drink, our aggressiveness or submissiveness, and our reproductive and parental behavior. And hormones do more than influence adult behavior; early in life they help to determine the development of bodily form and may even determine an individual’s behavioral capacities. Later in life the changing outputs of some endocrine glands and the body’s changing sensitivity to some hormones are essential aspects of the phenomena of aging.Communication within the body and the consequent integration of behavior were considered the exclusive province of the nervous system up to the beginning of the present century. The emergence of endocrinology as a separate discipline can probably be traced to the experiments of Bayliss and Starling on the hormone secretion. This substance is secreted from cells in the intestinal walls when food enters the stomach; it travels through the bloodstream and stimulates the pancreas to liberate pancreatic juice, which aids in digestion. By showing that special cells secret chemical agents that are conveyed by thebloodstream and regulate distant target organs or tissues. Bayliss and starling demonstrated that chemical integration could occur without participation of the nervous system.The term “hormone” was first used with reference to secretion. Starling derived the term from the Greek hormone, meaning “to excite or set in motion. The term “endocrine” was introduced shortly thereafter “Endocrine” is used to refer to glands that secret products into the bloodstream. The term “endocrine” contrasts with “exocrine”, which is applied to glands that secret their products though ducts to the site of action. Examples of exocrine glands are the tear glands, the sweat glands, and the pancreas, which secrets pancreatic juice through a duct into the intestine. Exocrine glands are also called duct glands, while endocrine glands are called ductless.11.What is the author’s main purpose in the passage?A.To explain the specific functions of various hormones.B.To provide general information about hormones.C.To explain how the term “hormone” evolved.D.To report on experiments in endocrinology.12.The passage supports which of the following conclusions?A.The human body requires large amounts of most hormones.B.Synthetic hormones can replace a person’s natural supply of hormones if necessary.C.The quantity of hormones produced and their effects on the body are related to a person’s age.D.The short child of tall parents very likely had a hormone deficiency early in life.13.It can be inferred from the passage that before the Bayliss and Starling experiments, most people believed thatchemical integration occurred only___.A.during sleep.B.in the endocrine glands.C.under control of the nervous system.D.during strenuous exercise.14.The word “liberate” could best be replaced by which of the following?A.EmancipateB.DischargeC.SurrenderD.Save15.According to the passage another term for exocrine glands is___.A.duct glandsB.endocrine glandsC.ductless glandsD.intestinal glands.TEXT DIf the old maxim that the customer is always right still has meaning, then the airlines that ply the world’s busiest air route between London and Paris have a flight on their hands.The Eurostar train service linking the UK and French capitals via the Channel Tunnel is winning customers in increasing numbers. In late May, it carried its one millionth passenger, having run only a limited service between London, Paris and Brussels since November 1994, starting with two trains a day in each direction to Paris and Brussels. By 1997, the company believes that it will be carrying ten million passengers a year, and continue to grow from there.From July, Eurostar steps its service to nine trains each waybetween London and Paris, and five between London and Brussels. Each train carries almost 800 passengers, 210 of them in first class.The airlines estimate that they will initially lose around 15%-20% of their London-Paris traffic to the railways once Eurostar starts a full service later this year (1995), with 15 trains a day each way. A similar service will start to Brussels. The damage will be limited, however, the airlines believe, with passenger numbers returning to previous levels within two to three years.In the short term, the damage caused by the 1 million people-levels traveling between London and Paris and Brussels on Eurostar trains means that some air services are already suffering. Some of the major carriers say that their passenger numbers are down by less than 5% and point to their rivals-Particularly Air France-as having suffered the problems. On the Brussels route, the railway company had less success, and the airlines report anything from around a 5% drop to no visible decline in traffic.The airlines' optimism on returning traffic levels is based on historical precedent. British Midland, for example, points to its experience on Heathrow Leeds Bradford service which saw passenger numbers fold by 15%when British Rail electrified and modernized the railway line between London and Yorkshire. Two years later, travel had risen between the two destinations to the point where the airline was carrying record numbers of passengers.16.British airlines confide in the fact that__.A.they are more powerful than other European airlines.B.their total loss won’t go beyond a drop of 5% passengers.C.their traffic levels will return in 2-3 years.D.traveling by rail can never catch up with traveling by air.17.The author’s attitude towards the drop of passengers may be described as__.A.worried.B.delightedC.puzzled.D.unrivaled.18.In the passage, British Rail (Para 6) is mentioned to__.A.provide a comparison with Eurostar.B.support the airlines’ optimism.C.prove the inevitable drop of air passengers.D.call for electrification and modernization of the railway.19.The railway’s Brussels route is brought forth to show that__.A.the Eurostar train service is not doing good business.B.the airlines can well compete with the railway.C.the Eurostar train service only caused little damage.D.only some airlines, such as Air France, are suffering.20.The passage is taken from the first of an essay, from which we may well predict that in the following part theauthor is going to__.A.praise the airlines’ clear-mindedness.B.warn the airlines of high-speed rail services.C.propose a reduction of London/Paris flights.D.advise the airlines to follow British Midland as their model.答案： 1-5 CDBDB 6-10 AACBD 11-15 BDCBA 16-20 ABCB。

PART V READING COMPREHENSION [25 MIN]In this section there are four passages followed by questions or unfinished statements, each with four suggested answers marked A, B, C and D. Choose the one that you think is the best answer.TEXT ARacket, din clamor, noise, whatever you want to call it, unwanted sound is America's most widespread nuisance. But noise is more than just a nuisance. It constitutes a real and present danger to people's health. Day and night, at home, at work, and at play, noise can produce serious physical and psychological stress. No one is immune to this stress. Though we seem to adjust to noise by ignoring it, the ear, in fact, never closes and the body still responds—sometimes with extreme tension, as to a strange sound in the night.The annoyance we feel when faced with noise is the most common outward symptom of the stress building up inside us. Indeed, because irritability is so apparent, legislators have made public annoyance the basis of many noise abatement programs. The more subtle and more serious health hazards associated with stress caused by noise traditionally have been given much less attention. Nevertheless, when we are annoyed or made irritable by noise, we should consider these symptoms fair warning that other thing may be happening to us, some of which may be damaging to our health.Of many health hazards to noise, hearing loss is the most clearly observable and measurable by health professionals. The other hazards are harder to pin down. For many of us, there may be a risk that exposure to the stress of noise increases susceptibility to disease and infection. The more susceptible among us may experience noise as a complicating factor in heart problems and other diseases. Noise that causes annoyance and irritability in health persons may have serious consequences for these already ill in mind or body.Noise affects us throughout our lives. For example, there are indications of effects on the unborn child when mothers are exposed to industrial and environmental noise. During infancy and childhood, youngsters exposed to high noise levels may have trouble falling asleep and obtaining necessary amounts of rest.Why, then, is there not greater alarm about these dangers? Perhaps it is because the link between noise and many disabilities or diseases has not yet been conclusively demonstrated. Perhaps it is because we tend to dismiss annoyance as a price to pay for living in the modern world. It may also be because we still think of hearing loss as only an occupational hazard.1. In Paragraph 1, the phrase "immune to" are used to mean ___.A.unaffected byB.hurt byC.unlikely to be seen byD.unknown by2.3. The author's attitude toward noise would best be described as ___.A.unrealisticB.traditionalC.concernedD.hystericalWhich of the following best states the main idea of the passage?A.Noise is a major problem; most people recognize its importance.B.Although noise can be annoying, it is not a major problem.C.Noise is a major problem and has not yet been recognized as such.D.Noise is a major problem about which nothing can be done.4.5. The author condemns noise essentially because it ___.A.is against the lawB.can make some people irritableC.is a nuisanceD.in a ganger to people's healthThe author would probably consider research about the effects noise has on people to be ___.A.unimportantB.impossible.C.a waste of moneyD.essentialTEXT BWhat we know of prenatal development makes all this attempt made by a mother to mold the character ofher unborn child by studying poetry, art, or mathematics during pregnancy seem utterly impossible. How could such extremely complex influences pass from the mother to the child? There is no connection between their nervous systems. Even the blood vessels of mother and child do not join directly. An emotional shock to the mother will affect her child, because it changes the activity of her glands and so the chemistry her blood. Any chemical change in the mother's blood will affect the child for better or worse. But we can not see how a looking for mathematics or poetic genius can be dissolved in blood and produce a similar liking or genius in the child.In our discussion of instincts we saw that there was reason to believe that whatever we inherit must be of some very simple sort rather than any complicated or very definite kind of behavior. It is certain that no one inherits a knowledge of mathematics. It may be, however, that children inherit more or less of a rather general ability that we may call intelligence. If very intelligent children become deeply interested in mathematics, they will probably make a success of that study.As for musical ability, it may be that what is inherited is an especially sensitive ear, a peculiar structure of the hands or the vocal organs connections between nerves and muscles that make it comparatively easy to learn the movements a musician must execute, and particularly vigorous emotions. If these factors are all organized around music, the child may become a musician. The same factors, in other circumstance might be organized about some other center of interest. The rich emotional equipment might find expression in poetry. The capable fingers might develop skill in surgery. It is not the knowledge of music that is inherited, then nor even the love of it, but a certain bodily structure that makes it comparatively easy to acquire musical knowledge and skill. Whether that ability shall be directed toward music or some other undertaking may be decided entirely by forces in the environment in which a child grows up.6. Which of the following statements is not true?A. Some mothers try to influence their unborn children by studying art and other subjects during theirpregnancy.B. It is utterly impossible for us to learn anything about prenatal development.C. The blood vessels of mother and child do not join directly.D. There are no connection between mother's nervous systems and her unborn child's.A mother will affect her unborn baby on the condition that ____.A. she is emotionally shocked7.B.she has a good knowledge of inheritanceC. she takes part in all kind of activitiesD. she sticks to studying8.9. According to the passage, a child may inherit____.A. everything from his motherB. a knowledge of mathematicsC. a rather general ability that we call intelligenceD. her mother's musical abilityIf a child inherits something from his mother, such as an especially sensitive ear, a peculiar structure of the hands or of the vocal organs, he will ____.A. surely become musicianB. mostly become a poetC. possibly become a teacherD. become a musician on the condition that all these factors are organized around music10. Which of the following is the best title for the passage?A. Role of Inheritance.B. An Unborn Child.C. Function of instincts.D. Inherited Talents.TEXT CThere are two factors which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ considerably , some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual— the sort of environment in which he is brought up. If an individual is handicapped(不利) environmentally, it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.The importance of environment in determining an individual's intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster(抚养) homes. Peter was raised by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark's I. Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.11. This selection can best be titled____________.A. Measuring Your IntelligenceB. Intelligence and EnvironmentC. The Case of Peter and MarkD. How the Brain Influences Intelligence12.13. The best statement of the main idea of this passage is that _______.A. human brains differ considerablyB. the brain a person is born with is important in determining his intelligenceC. environment is crucial in determining a person's intelligenceD. persons having identical brains will have roughly the same intelligence According to the passage, the average I. Q. is_______.A. 85 .B. 100C. 110D. 12514. The case history of the twins appears to support the conclusion that_______.A. individuals with identical brains seldom test at the same levelB. an individual's intelligence is determined only by his environmentC. lack of opportunity blocks the growth of intelligenceD. changes of environment produce changes in the structure of the brain15. This passage suggests that an individual's I. Q. _______.A. can be predicted at birthB. stays the same throughout his lifeC. can be increased by educationD. is determined by his childhoodTEXT DPersonality is，to large extent, inherent --A-type parents usually bring about A-type offspring. But the environment must also have a profound effect, since if competition is improtant to the parents, it is likely to become a major factor lives of their children.One place where children soak up A characteristics is school, which is, by its very nature, a highly competitive institution. Too many schools adopt the "win at all costs" moral standard and measure their success by sporting achievements. The current passion for making children compete against their classmates or against the clock produces a two-layer system, in which competitive A types seem in some way better than their B-type fellows. Being too keen to win can have dangerous consequences:remember that Pheidippides ,the first marathon runner, dropped dead seconds after saying:"Rejoice, we conquer!".By far the worst form of competition in school is the disproportionate emphasis on examinations . It is a rare school that allows pupils to concentrate on those things they do well.The merits of competition by examination are somewhat questionable, but competition in the certain knowledge of failure is positively harmful.Obviously, it is neither practical nor desirable that all A youngsters change into 'B's. The would needs types, and schools have an important duty to try to fit a child's personality to his possible future employment. It is top management.16. According to the author, what factors contribute to the building of personality?A. inheritanceb. inheritance, competition and environmentc. competitiond. environment17. Which of the following statements is not true according to the author of the passage?A.Schools usually adopt severe competitive policies.B. Students are often divided by competition results.C. School is place where children cultivate their characteristics.D. The stronger desire for winning, the better.18. The phrase "soak up" is closest in meaning to ____.A. pull upb. take upc. take ind. pull in19. What attitude does the author hold toward examinations in schools?A. positiveb. negativec. doubtfuld. neutral20. what suggestion does the author make concerning the management of schools?A.

专业英语四级（阅读）模拟试卷120(题后含答案及解析)题型有：1. 2.SECTION AIn this section there are several passages followed by ten multiple-choice questions. For each question, there are four suggested answers marked [A], [B], [C] and [D]. Choose the one that you think is the best answer.(1)Job stress and worrying about job security can both take a toll on a woman’s body, although the two issues affect female health differently, according to research presented last month at the American Heart Association’s Annual Meeting in Chicago. But whether chronic work-related stress is eating at your nerves or ballooning your waistline, there are natural solutions with no toxic side effects that you can use to relax the pressure. (2)In a recent study looking at work stress and women, researchers from Harvard and Brigham and Women’s Hospital studied more than 17,000 otherwise healthy women, generally in their 50s, enrolled in the Women’s Health Study for 10 years. Women who reported work-related strain, such as having little or no authority over decisions or being unable to contribute creativity and skills to the job, were up to 88 percent more likely to experience a heart attack than women who reported no work strain. Overall, working women reporting high job strain faced a 40 percent higher rate of cardiovascular(心血管的)disease, too. (3)Worrying about losing a job did not appear to increase heart attack risk, but it was linked to obesity, high blood pressure, and high cholesterol(胆固醇), all of which can eventually lead to cardiovascular disease. (4)Whether it’s a nightmarish cubicle neighbor, an unrelenting workload, or an ornery boss that has your stress meter ready to pop at any second, you can get a grip: It’s all about mind over matter. An August study published in the Proceedings of the National Academy of Sciences found that students taking part in Integrative Body-Mind Training(IBMT)enjoyed changes in white brain matter(within 11 hours of practice)that seemed connected to better regulation of emotions and behavior. (5)Although not very common in the U.S. yet, IBMT involves the practice of maintaining a state of restful alertness to tap into body-mind awareness while a trained coach guides your breathing and mental imagery. It’s somewhat similar to more widely available mindfulness based stress reduction(MBSR), which involves focusing on your present-moment draughts and feelings in a non-judgmental way. MBSR has been shown to help people make clearer decisions in times of crisis, which could help when all health breaks loose at the office.(6)Previous research out of the University of Oregon has found that you could adopt stress-zapping properties of Integrative Body-Mind Training(IBMT)before the workweek’s out. After practicing it for 20 minutes a day for five days in a row, participants reported reduced stress and increased energy. Prevention suggests this intro IBMT exercise: Sit quietly in a comfortable position. Close your eyes and think of your mind as a full cup; as thoughts come and go, keep returning to an image of the cup becoming empty. Repeat for five minutes. (7)Regardless of your meditationstyle, know this: Compared to non-meditators, women who practice meditation enjoy up to a 66 percent drop in stress hormone levels, which can dramatically improve heart health. (8)If you’re in need of an emergency quick freak-out fix, reach for a piece of gum.(Avoid artificial sweetened gum, though—some are linked to health issues.)One study found that chewing gum boosts blood flow to the brain by up to 40 percent, helping you stay calm and in the present. This prevents you from pondering over some aggravating office event. (9)You don’t need to be a monk to enjoy the benefits of meditation. In fact, more and more Western integrative medicine practitioners are using it as a nontoxic health improver.1．According to the passage, which of the following can probably lead to women’s work-related strain?A．They are not creative enough in their work.B．They could not afford to lose their job.C．They have no say in decision-making.D．They are underpaid compared with men.正确答案：C解析：根据work—related strain定位到第2段。

同学们在做完试题后，一定要认真对答案并找出自己做错的原因。

大家加油呀，冲冲冲！祝大家都能高分通过考试！Part ⅢReading Comprehension (35 minutes)Directions: There are 4 passages in this part.Each passage is followed by some questions or unfinished statements.For each of them there are four choices marked A),B),C) and D).You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center.Questions 21 to 25 are based on the following passage:Some radio singals were heard in 1967.They were coming from a point in the sky where there was unknown star.They were coming very regularly,too:about once a second,if they were controlled by clock.The scientists who heard the signals did not tell anybody else.They were rather afraid to tell in case they frightened people.The signals were coming from a very small body—no bigger,perhaps than the earth.Wasthat why no light could be seen from it?Or were the signals coming from a planet that belonged to some other star? There was no end to the questions,but the scientists kept the news secret.“Perhaps there are intelligent beings out there.”they thought,“who are trying to send messages to other planets,or to us?So the news was not given to the newspaper.Instead,the scientists studied the signals and searched for others like them...Well,all that happened in 1967 and 1968.Since then scientists have learnt more about those strange,regular,radio signals.And they have told the story,of course.The signals do not come from a planet;they come from a new kind of star called a “pulsar””.About a hundred other pulsars have now been found,and most of them are very like the first one.Pulsars are strong radio stars.They are the smallest but the heaviest stars we know at present.A handful of pulsar would weigh a few thousand tons.Their light—if they give much light—is too small for us to see.But we can be sure of this,no intelligent beings are living on them.21. The radio signals discussed in this passage____.A.were regularB.were controlled by a clockC.were heard in 1967 onlyD.were secret messages22. The radio singals were sent by____.A.a satelliteB.a planetC.a sky body which was unknown at that timeD.intelligent beings who were unknown at that time23. The scientists did not tell people about the signals because____.A.the singals stood for secret messagesB.people would ask them too many questionsC.they did not want to frighten peopleD.they stood for unimportant messages24. A pulsar is____.A. a small heavy star which sends out strong radio signals and cannot be seenB. a small heavy planet which sends out strong radio signals and cannot be seenC. a small heavy satellite which sends out strong radio signals and cannot be seenD. a small intelligent being who sends out strong radio signals and cannot be seen25. Which of the following is true?A.One of the pulsars found by scientists sends radio signals.B.Pulsar began to send radio singals in 1967.C.Scientists have searched for pulsars for many years but found none.D.Scientists have found many pulsars since 1967. rn life and ancient life.27. “one out of seven”refers to____.A.more than a third of the lands' earthB.the percentage of the earth's land that is desert-likeC.the number of people who live in dry regionsD.a day of a week28. In paragraph 2,“they are taken to the greener lands in the south.”They refers to____.A.the Sahel farm landB.the farmersC.the cattlesD.the trees29. How many ideas for saving the land are described?A.Five.B.Two.C.Four.D.Three.30. Which of the following statements is true, according to the passage?A.The earth's desert are slowly spreading.B.One out of 10 people lives in dry regions.C.Their life in the desert is threatened now by traditional problems.D.New water wells can solve the problem in Africa's desert.Questions 31 to 35 are based on the following passage:Telephone, television, radio, and telegraph all help people communicate with each other. Because of these devices, ideas and news of events spread quickly all over the world. For example, within seconds, people can know the results of an election in another country. An international football match comes into the homes of everyone with a television set.News of a disaster such as an earthquake or a flood can bring help from distant countries within hours, help is on the way. Because of modern technology like the satellites that travel around the world, information travels fast.How has this speed of communication changed the world? To many people,the world has become smaller. Of course this does not mean that the world is actually physically smaller. It means that the world seems smaller. Two hundred years ago,communication between the continents took a long time. All news was carried on ships that took weeks or even months to cross the ocean. In the seventeenth and eighteenth centuries,it took six weeks for news from Europe to reach America.This time difference influenced people's actions. For example, one battle, orfight, in the War of 1812 between England and the United States could have been avoided. A peace agreement had already been signed. Peace was made in England, but the news of peace took six weeks to reach America. During these six weeks, the large and serious Battle of New Orleans was fought. Many people lost their lives after a peace treaty had been signed.They would not have died if news had come in time.In the past,communication took much time than it does now.There was a good reason why the world seemed so much larger than it does today.31. News spreads fast because of____.A.modern transportationB.new technologyC.the change of the worldD.a peace agreement32. According to this passage,____is very important to people in a disaster area.A.fast communicationB.modern technologytest newsD.new ideas33. Which of the following statements is true?A.The world now seems smaller because of faster communication.B.The world is actually smaller today.C.The world is changing its size.D. The distance between England and America has changed since the War of 181234. Two hundred years ago,news between the continents was carried____.A.by telephone and telegraphB.by landC.by airD.by sea35. The New Orleans Battle could have been avoided if the peace agreement had been signed____.A.by both sidesB.in timeC.in AmericaD.in EnglandQuestions 36 to 40 are based on the following passage:The concept of personal choice in relation to health behaviors is an important one.An estimated 90 percent of all illnesses may be preventable if individuals would make sound personal health choices based upon current medical knowledge.We all enjoy our freedom of choice and do not like to see it restricted when it is within the legal and moral boundaries of society.[ZZ)]The structure of American society allows us to make almost all our own personal decisions that may concern our health.If we so desire,we can smoke,drink excessively, refuse to wear seat belts,eatwhatever foods we want,and live a completely sedentary life-style without any excuse.The freedom to make such personal decisions is a fundamental aspect of our society,although the wisdom of these decisions can be questioned.Personal choices relative to health often cause a difficulty.As one example,a teenager may know the facts relative to smoking cigarettes and health but may be pressured by friends into believing it is the socially accepted thing to do. A multitude of factors,both inherited and environmental,influence the development of health related behaviors,and it is beyond the scope of this text to discuss all these factors as they may affect any given individual.However,the decision to adopt a particular health-related behavior is usually one of personal choices.There are healthy choices and there are unhealthy choices.In discussing the moral of personal choice,Fries and Crapo drew a comparison.[ZZ(Z]They suggest that to knowingly give oneself over to a behavior that has a statistical probability of shortening life is similar to attempting suicide.[ZZ)]Thus,for those individuals who are interested in preserving both the quality and quantity of life,personal health choices should reflect those behaviors that are associated with statistical probability of increased vitality and longevity.36. The concept of personal choice concerning health is important because____.A.personal health choices help cure most illnessesB.it helps raise the level of our medical knowledgeC.it is essential to personal freedom in American societyD.wrong decisions could head to poor health37. To “live a completely sedentary life style”(Para. 1) in the passage means____.”A.to live an inactive lifeB.to live a decent lifeC.to live a life with complete freedomD.to live a life of vice38. Sound personal health choice is often difficult to make because____.A.current medical knowledge is still insufficientB.there are many factors influencing our decisionsC.few people are willing to trade the quality of life for longevityD.people are usually influenced by the behavior of their friends39. To knowingly allow oneself to pursue unhealthy habits is compared by Fries and Crapo to____.A.improving the quality of one's lifeB.limiting one's personal health choiceC.deliberately ending one's lifeD.breaking the rules of social behavior40. According to Fries and Crapo sound health choices should be based on____.A.personal decisionsws of societyC.statistical evidenceD.opinions of friendsPart ⅤWriting (30 minutes)Directions:For this part,you are allowed 30 minutes to write a composition with the title ON Friendship.Your composition should be no less than 120 words.Remember to write your composition neatly.You should also base your composition on the outline below.1.The need for friends2.True friendship3.My principle in making friends答案1短文大意1967年人类收到了一些太空信号。

英语专业四级阅读理解模拟题及参考答案Within that exclusive group of literary characters who have survived through the centuries--from Hamlet to Huckleberry Finn--few can rival the cultural impact of Sherlock Holmes.Since his first public appearance20years ago,the gentleman with the curved pipe and a taste for cocaine,the master of deductive reasoning and elaborate disguise,has left his mark everywhere--in crime literature,film and television,cartoons and comic books.At Holmes'side,of course,was his trusted friend Dr.Watson.Looming even larger,however,was another doctor,one whose medical practice was so slow it allowed him plenty of time to pursue his literary ambition.His name:Arthur Conan Doyle.As the creator of these fictional icons, Conan Doyle has himself become something of a cult figure,the object of countless critical studies,biographies and fan clubs.Conan Doyle was born in Edinburgh in1859,in a respectable middle-class Catholic family.Still, it was far from an easy life.There was never enough money;they moved frequently in search of lower rents;and his father,a civil servant and illustrator was an alcoholic who had to be institutionalized.Yet the early letters he wrote to his mother are surprisingly optimistic,concerned mainly with food,clothes,allowances and schoolwork.At14came his first unforgettable visit to London,including Madame Tussaud's,where he was"delighted with the room of Horrors,and the images of the murderers."A superb student,Conan Doyle went on to medical school,where he was attracted by Dr.Joseph Bell,a professor with an uncanny ability to diagnose patients even before they opened their mouths.For a time he worked as Bell's outpatient clerk and would watch,amazed,at how the location of a callus could reveal a man's profession,or how a quick look at a skin rash told Bell that the patient had once lived in Bermuda.In1886,Conan Doyle outlined his first novel,A Study in Scarlet,which he described as"a simple tale of mystery to make a little extra money."Its main character,initially called Sherringford Hope and later called Sherlock Holmes,was based largely on Bell.But Holmes'first appearance went almost unnoticed,and the struggling doctor devoted nearly all of his spare time to writing long historical novels in the style of Sir Walter Scott—novels that he was convinced would make his reputation.It wasn't to be.In1888,Holmes reappeared in A Scandal in Bohemia,a short story in Strand Magazine.And this time,its hero took an immediate hit and Conan Doyle's life would never be the same.1.The typical features of Sherlock Holmes were all EXCEPTA.rational.B.sociable.C.intelligent.D.cunning.2.Which of the following is NOT true about Conan Doyle and his family?A.He came from a middle-class family.B.They led a hard life in Edinburgh.C.His father was addicted to drinking.D.His mother had received little education.3.How did Conan Doyle feel about his first visit to London?A.It was horrible.B.It was pleasant.C.It was awful.D.It was memorable.4.We can infer from the last paragraph thatA.the more calluses a person has,the more professional he would be.B.writers often base their writing on personal experiences.C.Conan Doyle has gone through a period of hardship on his way to success.D.inspiration was very important for a person to create something.5.Conan Doyle's short story"A Scandai in Bohemia"has proved to be__at last.A.successfulB.powerfulC.ridiculousD.frustrating参考答案与解析：1．[B]细节判断题。

They can even play chess, write poetry, or compose music. But perhaps the most interesting applications will be for personal use. In some countries, modified television sets have been connected by telephone to a very large computer. Users dial a few numbers on the telephone to get information from the large computer such as schedules for airplanes, information from dictionaries, or weather forecasts. They can also use the computer to do complicated calculations and to play games.1．正确答案：Nearly everything we do in the modern world is helped or even controlled by computers.

Listen to the conversations carefully and then answer the questions that follow.听力原文：F: Doctor Smith, today I’d like to ask you about the fact of lying of doctors.M: It’s actually quite common in this field.F: Can you give me an example?M: Well, one of the patients, he came in for a routine physical checkup just before going on vacation with his family. Though he feels in perfect health, we’ve found that he has a form of cancer that will cause him to die within six months. He is only 46 years old!F: Poor thing. Does he know it?M: No. And that’s worrying me. I mean it’s best to let him know. But there is also the need to conceal this brutal news, or at 1 east we should conceal the truth until after the family vacation.F: What do you usually do under such circumstances?M: We often see important reasons to lie for the patient’s own sake; in our eyes, such lies differ from self-serving ones. We doctors sincerely believe that the seriously ill people do not want to know the truth about their condition, and informing them risks destroying their hope, so that they recover more slowly, or deteriorate faster, perhaps even commit suicide.F: But isn’t this sometimes dangerous? I mean dying patients especially can’t make decisions about the end of life: about whether or not they should enter a hospital, or have surgery; about where and with whom they should spend their remaining time; about how they should bring their affairs to a close and take leave.M: What you’ve said, I admit, is also reasonable. But not only in medicine, but in other professions like in law, government, or the social sciences as well, people may find themselves repeatedly in difficulty where serious consequences seem avoidable only through deception.2．What is not true about the patient mentioned in the beginning?A．He came in for a routine physical checkup.B．He is going on vacation with his family.C．He feels in perfect health.D．He is only 36 years old!正确答案：D解析：原文中有“He is only 46 years old!”一句，可判断D项错误。

英语专业四级阅读理解模拟题A simple piece of rope hangs between some environmentally friendly Americans and their neighbors. On one side stand those who have begun to see clothes dryers as wasteful consumers of energy (up to 6% of total electricity) and powerful emitters of carbon dioxide (up to a ton of CO2 per household every year). As an alternative, they are turning to clotheslines as part of what Alexander Lee, an environmentalist, calls "what-I-can- do environmentalism."But on the other side are people who oppose air-drying laundry outside on aesthetic grounds. Increasingly, they have persuaded community and homeowners associations(HOAs) across the U.S. to ban outdoor clotheslines, which they say not only look unsightly but also lower surrounding property values. Those actions, in turn, have sparked a right-to-dry movement that is pressing for legislation to protect the choice to use clotheslines. Only three states--Florida, Hawaii and Utah--have laws written broadly enough to protect clotheslines. Right-to-dry advocates argue that there should be more.Matt Reck is the kind of eco-conscious guy who feeds his trees with bathwater and recycles condensation drops from his air conditioners to water plants. His family also uses a clothesline. But Otto Hagen, president of Reck's HOA in Wake Forest, N.C., notified him that a neighbor h, ad complained about his line. The Recks ignored the warning and still dry their clothes on a rope in the yard. "Many people claim to be environmentally friendly but don't take matters into their own hands," says Reck. HOAs Hagen has decided to hold off taking action. "I'm not going to go crazy," he says. "But if Matt keeps his line and more neighbors complain, I'll have to address it again."North Carolina lawmakers tried and failed earlier this year to insert language into an energy bill that would expressly prevent HOAs from regulating clotheslines. But the issue remains a touchy one with HOAs and real estate agents. "Most aesthetic restrictions are rooted, to a degree, in the belief that homogenous (统一协调的) exteriors are supportive of property value," says Sara Stubbins, executive director of the Community Association Institute's North Carolina chapter. In other words, associations worry that housing prices will fall if prospective buyers think their would-be neighbors are too poor to afford dryers.Alexander Lee dismisses the notion that clotheslines devalue property assets, advocating that the idea "needs to change in light of global warming." "We all have to do at least something to decrease our carbon footprint," Alexander Lee says.1.What is NOT mentioned as a disadvantage of using clothes dryers?A.Electricity consumption.B.Air pollution.C.Waste of energy.D.Ugly looking.2.Which of the following is INCORRECT?A.Opposers think air-drying laundry would devalue surrounding assets.B.Opposers consider the outdoor clothesline as an eyesore to the scenery.C.Right-to-dry movements led to the pass of written laws to protect clotheslines.D.Most of states in the US have no written laws to protect clotheslines.3.What is the HOAs' attitude towards the regulation of outdoor clotheslines?A.Concerned.B.Impartial.C.Supportive.D.Unclear.4.In the last paragraph Alexander Lee recommends thatA.clotheslines should be banned in the community.B.clotheslines wouldn't lessen the property values.C.the globe would become warmer and warmer.D.we should protect the environment in the community.5.An appropriate title for the passage might beA.Opinions on Environmental Protection.B.Opinions on Air-drying Laundry.C.What-I-Can-Do Environmentalism.D.Restrictions on Clotheslines.参考答案与解析：文章概要：本文探讨是否该用晾衣绳在室外晾晒衣服。

大学英语四级长篇阅读专项强化真题试卷27(题后含答案及解析) 题型有：1.The Changes Facing Fast FoodA)Fast-food firms have to be a thick-skinned bunch. Health experts regularly criticise them severely for selling food that makes people fat. Critics even complain that McDonald’s, whose logo symbolises calorie excess, should not have been allowed to sponsor the World Cup. These are things fast-food firms have learnt to cope with. But not perhaps for much longer. The burger business faces more pressure from regulators at a time when it is already adapting strategies in response to shifts in the global economy.B)Fast food was once thought to be recession-proof. When consumers need to cut spending, the logic goes, cheap meals like Big Macs and Whoppers become even more attractive. Such “trading down” proved true for much of the latest recession, when fast-food companies picked up customers who could no longer afford to eat at casual restaurants. Traffic was boosted in America, the home of fast food, with discounts and promotions, such as $1 menus and cheap combination meals.C)As a result, fast-food chains have weathered the recession better than their more expensive competitors. In 2009 sales at full-service restaurants in America fell by more than 6% , but total sales remained about the same at fast-food chains. In some markets, such as Japan, France and Britain, total spending on fast food increased. Same-store sales in America at McDonald’s, the world’s largest fast-food company, did not decline throughout the downturn. Panera Bread, an American fast-food chain known for its fresh ingredients, performed well, too, because it offers higher-quality food at lower prices than restaurants.D)But not all fast-food companies have been as fortunate. Many, such as Burger King, have seen sales fall. In a severe recession, while some people trade down to fast food, many others eat at home more frequently to save money. David Palmer, an analyst at UBS, a bank, says smaller fast-food chains in America, such as Jack in the Box and Carl’s Jr. , have been hit particularly hard in this downturn because they are competing with the global giant McDonald’s, which increased spending on advertising by more than 7% last year as others cut back.E)Some fast-food companies also sacrificed their own profits by trying to give customers better value. During the recession companies set prices low, hoping that once they had tempted customers through the door they would be persuaded to order more expensive items. But in many cases that strategy did not work. Last year Burger King franchisees(特许经营人)sued(起诉)the company over its double-cheeseburger promotion, claiming it was unfair for them to be repuired to sell these for $1 when they cost $1.10 to make. In May a judge ruled in favour of Burger King. Nevertheless, the company may still be cursing its decision to promote cheap choices over more expensive ones because items on its “value menu” now account for around 20% of all sales, up from 12% last October.F)Analysts expect the fast-food industry to grow modestly this year. But the downturn is making companies rethink their strategies.Many are now introducing higher-priced items to entice(引诱)consumers away from $1 specials. KFC, a division of Yum! Brands, which also owns Taco Bell and Pizza Hut, has launched a chicken sandwich that costs around $5. And in May Burger King introduced barbecue(烧烤)pork ribs at $7 for eight.G)Companies are also trying to get customers to buy new and more items, including drinks. McDonald’s started selling better coffee as a challenge to Starbucks. Its “McCafe”line now accounts for an estimated 6% of sales in America. Starbucks has sold rights to its Seattle’s Best coffee brand to Burger King, which will start selling it later this year.H)As fast-food companies shift from “super size” to “more buys” , they need to keep customer traffic high throughout the day. Many see breakfast as a big opportunity, and not just for fatty food. McDonald’s will start selling porridge(粥)in America next year. Breakfast has the potential to be very profitable, says Sara Senatore of Bernstein, a research firm, because the margins can be high. Fast-food companies are also adding midday and late-night snacks, such as blended drinks and wraps. The idea is that by having a greater range of things on the menu, “ we can sell to consumers products they want all day,” says Rick Carucci, the chief financial officer of Yum! Brands.I)But what about those growing waistlines? So far, fast-food firms have cleverly avoided government regulation. By providing healthy options, like salads and low-calorie sandwiches, they have at least given the impression of doing something about helping to fight obesity(肥胖症). These offerings are not necessarily loss-leaders, as they broaden the appeal of outlets to groups of diners that include some people who don’t want to eat a burger. But customers cannot be forced to order salads instead of fries.J)In the future, simply offering a healthy option may not be good enough. “Every packaged-food and restaurant company I know is concerned about regulation right now,” says Mr. Palmer of UBS. America’s health-reform bill, which Congress passed this year, requires restaurant chains with 20 or more outlets to put the calorie-content of items they serve on the menu. A study by the National Bureau of Economic Research, which tracked the effects on Starbucks of a similar calorie-posting law in New York City in 2007, found that the average calorie-count per transaction fell 6% and revenue increased 3% at Starbucks stores where a Dunkin Donuts outlet was nearby—a sign, it is said, that menu-labelling could favour chains that have more healthy offerings. K)In order to avoid other legislation in America and elsewhere, fast-food companies will have to continue innovating(创新). Walt Riker of McDonald’s claims the change it has made in its menu means it offers more healthy items than it did a few years ago. “We probably sell more vegetables, more milk, more salads, more apples than any restaurant business in the world,”he says. But the recent proposal by a county in California to ban McDonald’s from including toys in its high-calorie “Happy Meals” , because legislators believe it attracts children to unhealthy food, suggests there is a lot more left to do.1．Some people propose laws be made to stop McDonald’s from attaching toys to its food specials for children.正确答案：K解析：该段说明在快餐业进行创新和改良的大环境下，麦当劳也对其食品进行了改良，提供了更多健康食品，但是高热最食品仍然存在，为促销其儿童“快乐套餐”，麦当劳会在卖套餐的同时附赠玩具，立法者认为这种做法会引诱孩子吃不健康的食物，因此提议立法禁止该行为。

PART V READING COMPREHENSION [25 MIN]In this section there are four passages followed by questions or unfinished statements, each with four suggested answers marked A, B, C and D. Choose the one that you think is the best answer.TEXT AWe can begin our discussion of "population as global issue" with what most persons mean when they discuss "the population problem": too many people on earth and a too rapid increase in the number added each year. The facts are not in dispute, It was quite right to employ the analogy that likened demographic growth to "a long, thin powder fuse that burns steadily and haltingly until it finally reaches the charge and explodes."To understand the current situation, which is characterized by rapid increases in population, it is necessary to understand the history of population trends. Rapid growth is a comparatively recent phenomenon. Looking back at the 8,000 years of demographic history, we find that populations have been virtually stable or growing very slightly for most of human history. For most of our ancestors, life was hard, often nasty, and very short. There was high fertility in most places, but this was usually balanced by high mortality. For most of human history, it was seldom the case that one in ten persons would live past forty, while infancy and childhood were especially risky periods. Often, societies were in clear danger of extinction because death rates could exceed their birthrates. Thus, the population problem throughout most of history was how to prevent extinction of the human race.This pattern is important to notice. Not only does it put the current problems of demographic growth into a historical perspective, but it suggests that the cause of rapid increase in population in recent years is not a sudden enthusiasm for more children, but an improvement in the conditions that traditionally have caused high mortality.Demographic history can be divided into two major periods: a time of long, slow growth which extended from about 8,000 BC.till approximately AD. 1650. In the first period of some 9600 years, the population increased from some 8 million to 500 million in 1650. Between 1650 and the present, the population has increased from 500 million to more than 4 billion. And it is estimated that by the year 2000 there will be 6.2 billion people throughout the world. One way to appreciate this dramatic difference in such abstract numbers is to reduce the time frame to something that is more manageable. Between 8000BC and 1650, an average of only 50,000 persons was being added annually to the world's population each year. At present, this number is added every six hours. The increase is about 80,000,000 persons annually.1.Which of the following demographic growth pattern is most suitable for the long thin powder fuse analogy?A.A virtually stable or slightly decreasing period and then a sudden explosion of population.B.A slow growth for a long time and then a period of rapid, dramatic increase.C.Too many people on earth and a few rapid increase in the number added each year.D.A long period when death rates exceeds birthrates and then a short period with higher fertility and lowermortality.2.During the first period of demographic history, societies were often in danger of extinction because___.A.only one in ten persons could live past 40.B.there was higher mortality than fertility in most places.C.it was too dangerous to have babies due to the poor conditions.D.our ancestors had little enthusiasm for more children.3.Which statement is true about population increase?A.There might be an increase of 2.2 billion persons from now to the year 2000.B.About 50,000 babies are born every six hours at present.C.Between 8000 BC and the present, the population increase is about 80,000,000 persons each year.D.The population increased faster between 8000BC and 1650 than between 1650 and the present.4.The author of the passage intends to___.A.warn people against the population explosion in the near future.pare the demographic growth pattern in the past with that after 1650.C.find out the cause for rapid increase in population in recent years.D.present us a clear and complete picture of the demographic growth.5.The word "demographic" in the first paragraph means___.A.statistics of human.B.surroundings study.C.accumulation of human.D.development of human.TEXT BChinese Americans today have higher incomes than Americans in general and higher occupational status. The Chinese have risen to this position despite some of the harshest discrimination and violence faced by any immigrants to the United States in the history of this country. Long confined to a narrow range of occupations they succeeded in those occupations and then spread out into other areas in later years, when opportunities finally opened up for them. Today much of the Chinese prosperity is due to the simple fact that they work more and have more (usually better) education than others. Almost one out of five Chinese families has three or more income earners compared to one out of thirteen for Puerto Ricans, one out of ten among American Indians, and one out of eight among Whites. When the Chinese advantages in working and educational are held constant, they have no advantage over other Americans. That is in a Chinese Family with a given number of people working and with a given amount of education by the head of the family, the income is not only about average for such families, and offer a little less than average.While Chinese Americans as a group are prosperous and well-educated Chinatowns are pockets of poverty, and illiteracy is much higher among the Chinese than among Americans in general. Those paradoxes are due to sharp internal differences. Descendants of the Chinese Americans who emigrated long ago from Toishan Province have maintained Chinese values and have added acculturation to American society with remarkable success. More recent Hong Kong Chinese are from more diverse cultural origins, and acquired western values and styles in Hong Kong, without having acquired the skills to proper and support those aspirations in the American economy. Foreign-born Chinese men in the United States are one-fourth lower incomes than native-born Chinese even though the foreign-born have been in the United States an average of seventeen years. While the older Hong Kong Chinese work tenaciously to sustain and advance themselves, the Hong Kong Chinese youths often react with resentment and antisocial behavior, including terrorism and murder. The need to maintain tourism in Chinatown causes the Chinese leaders to mute or downplay these problems as much as possible.6.According to the passage, today, Chinese Americans owe their prosperity to___.A.their diligence and better education than others.B.their support of American government.C.their fight against discriminations.D.advantages in working only.7.The passage is mainly concerned with___.A.chinese Americans today.B.social status of Chinese Americans today.C.incomes and occupational status of Chinese Americans today.D.problems of Chinese Americans today.8.Chinatowns are pockets of poverty, as is probably associated with___.A.most descendants of Chinese Americans are rebelling.B.most descendants of Chinese Americans are illiterate.C.sharp internal difference between Chinese coming from different cultural backgrounds.D.only a few Chinese Americans are rich.9.Which of the following statements is not true according to this articleA.As part of the minority, Chinese Americans are still experiencing discrimination in American today.B.Nowadays, Chinese Americans are working in wider fields.C.Foreign-born Chinese earn lower income than native-born Chinese Americans with the similar advantagesin the U.S.D.None of the above.10.According to the author, which of the following can best describe the older Hong Kong Chinese and theyoungerA.Tenacious; rebellion.B.Conservative; open-minded.C.Out-of-date; fashionable.D.Obedient; disobedient.TEXT CA controversy erupted in the scientific community in early 1998 over the use of DNA (deoxyribonucleic acid ) fingerprinting in criminal investigations. DNA fingerprinting was introduced in 1987 as a method to identify individuals based on a pattern seen in their DNA, the molecule of which genes are made. DNA is present in every cell of the body except red blood cells. DNA fingerprinting has been used successfully in various ways, such as to determine paternity where it is not clear who the father of a particular child is. However, it is in the area of criminal investigations that DNA fingerprinting has potentially powerful and controversial uses.DNA fingerprinting and other DNA analysis techniques have revolutionized criminal investigations by giving investigators powerful new tools in the attempt to trove guilt, not just establish innocence. When used in criminal investigations, a DNA fingerprint pattern from a suspect is compared with a DNA fingerprint pattern obtained from such material as hairs or blood found at the scene of a crime. A match between the two DNA samples can be used as evidence to convict a suspect.The controversy in 1998 stemmed form a report published in December 1991 by population geneticists Richard C. Lewontin of Harvard University in Cambridge, Mass., and Daniel L. Hartl called into question the methods to calculate how likely it is that a match between two DNA fingerprints might occur by chance alone. In particular, they argued that the current method cannot properly determine the likelihood that two DNA samples will match because they came from the same individual rather than simply from two different individuals who are members of the same ethnic group. Lewontin and Hartl called for better surveys of DNA patterns methods are adequate.In response to their criticisms, population geneticists Ranajit Chakraborty of the University of Texas in Dallas and Kenneth K.Kidd of Yale University in New Haven, Conn., argued that enough data are already available to show that the methods currently being used are adequate. In January 1998, however, the federal Bureau of Investigation and laboratories that conduct DNA tests announced that they would collect additional DNA samples form various ethnic groups in an attempt to resolve some of these questions. And, in April, a National Academy of Sciences called for strict standards and system of accreditation for DNA testing laboratories.11.efore DNA fingerprinting is used, suspects____.A.would have to leave their fingerprints for further investigationsB.would have to submit evidence for their innocenceC.could easily escape conviction of guiltD.cold be convicted of guilt as well12.DNA fingerprinting can be unreliable when ____.A.the methods used for blood- cell calculation are not accurateB.two different individuals of the same ethnic group may have the same DNA fingerprinting patternC.a match is by chance left with fingerprints that happen to belong to two different individualsD.two different individuals leave two DNA samples.13.To geneticists like Lewontin and Hartl, the current method ____.A.is not so convincing as to exclude the likelihood that two DNA samples can never come from twoindividualsB.is arguable because two individuals of the same ethnic group are likely to have the same DNA pattern.C.Is not based on adequate scientific theory of geneticsD.Is theoretically contradictory to what they have been studying14.The attitude of the Federal Bereau of Investigation shows that ____.A.enough data are yet to be collected form various ethnic groups to confirm the unlikelihood of two DNAsamples coming from two individual membersB.enough data of DNA samples should be collected to confirm that only DNA samples form the same personcan matchC.enough data are yet to be collected from various ethnic groups to determine the likelihood of two differentDNA samples coming form the same personD.additional samples from various ethnic groups should be collected to determine that two DNA samples areunlikely to come from the same person15.National Academy of Sciences holds the stance that ____.A.DNA testing should be systematizedB.Only authorized laboratories can conduct DNA testingC.The academy only is authorized to work out standards for testingD.The academy has the right to accredit laboratories for DNA testingTEXT DMost of us are taught to pay attention to what is said—the words. Words do provide us with some information, but meanings are derived from so many other sources that it would hinder our effectiveness as a partner to a relationship to rely too heavily on words alone. Words are used to describe only a small part of the many ideas we associate with any given message. Sometimes we can gain insight into some of those associations if we listen for more than words. We don't always say what we mean or mean what we say. Sometimes our words don't mean anything except " I'm letting off some steam. I don't really want you to pay close attention to what I'm saying. Just pay attention to what I'm feeling." Mostly we mean several things at once. A person wanting to purchase a house says to the current owner, "This step has to be fixed before I'll buy." The owner says, " It's been like that for years." Actually, the step hasn't been like that for years, but the unspoken message is: " I don't want to fix it. We put up with it. Why can't you?" The search for a more expansive view of meaning can be developed of examining a message in terms of who said it, when it occurred, the related conditions or situation, and how it was said.When a message occurs can also reveal associated meaning. Let us assume two couples do exactly the same amount of kissing and arguing. But one couple always kisses after an argument and the other couple always argues after a kiss. The ordering of the behaviors may mean a great deal more than the frequency of the behavior.A friend's unusually docile behavior may only be understood by noting that it was preceded by situations that required an abnormal amount of assertiveness. Some responses may be directly linked to a developing pattern of responses and defy logic. For example, a person who says "No!" to a serials of charges like "You're dumb," "You're lazy," and "You're dishonest," may also say "No!" and try to justify his or her response if the next statement is "And you're good looking."We would do well to listen for how messages are presented. The words, "If sure has been nice to have you over," can be said with emphasis and excitement or ritualistically. The phrase can be said once or repeated several times. And the meanings we associate with the phrase will change accordingly. Sometimes if we say something infrequently it assumes more importance; sometimes the more we say something the less importance it assumes.16.Effective communication is rendered possible between two conversing partners, if ___.A.they use proper words to carry their ideas.B.they both speak truly of their own feelings.C.they try to understand each other's ideas beyond words.D.they are capable of associating meaning with their words.17."I'm letting off some steam" in paragraph 1 means___.A.I'm just calling your attention.B.I'm just kidding.C.I'm just saying the opposite.D.I'm just giving off some sound.18.The house-owner's example shows that he actually means___.A.the step has been like that for years.B.he doesn't think it necessary to fix the step.C.the condition of the step is only a minor fault.D.the cost involved in the fixing should be shared.19.Some responses and behaviors may appear very illogical, but are justifiable if___.A.linked to an abnormal amount of assertiveness.B.seen as one's habitual pattern of behavior.C.taken as part of an ordering sequence.D.expressed to a series of charges.20.The word "ritualistically" in the last paragraph equals something done___.A.without true intention.B.light-heartedly.C.in a way of ceremony.D.with less emphasis.答案： 1-5 ABADA 6-10 ACCCA 11-15 CBABB 16-20 DBABC。

英语四级阅读理解模拟练习及答案详解在英语学习过程中，阅读理解力量是学习者进展语言力量的基础和手段。

国内的各类英语考试中几乎都有阅读理解题型，高校英语四级考试也不例外。

高校英语四级阅读理解试题是试卷中分值最重的题型，为了提高大家的阅读水平，下面是我为大家带来英语四级阅读理解模拟练习及答案详解，盼望对大家的学习有所关心!Directions:There are 2 passages in this section.Each passage is followed by some questions or unfinished statements.For each of them there are four choices marked A),B),C) and D) .You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 57 to 61 are based on the following passage.There is a new type of small advertisement becoming increasingly common in newspaper classified columns. It is sometimes placed among "situations vacant', although it does not offer anyone a job, and sometimes it appears among "situations wanted', although it is not placed by someone looking for a job, either. What it does is to offer help in applying for a job."Contact us before writing your application', or "Make use of our long experience in preparing your curriculum vitae or job history', is how it is usually expressed. The growth and apparentsuccess of such a specialized service is, of course, a reflection on the current high levels of unemployment. It is also an indication of the growing importance of the curriculum vitae (or job history), with the suggestion that it may now qualify as an art form in its own right.There was a time when job seekers simply wrote letters of application. "Just put down your name, address, age and whether you have passed any exams', was about the average level of advice offered to young people applying for their first jobs when I left school. The letter was really just for openers, it was explained, everything else could and should be saved for the interview. And in those days of full employment the technique worked. The letter proved that you could write and were available for work. Your eager face and intelligent replies did the rest.Later, as you moved up the ladder, something slightly more sophisticated was called for. The advice then was to put something in the letter which would distinguish you from the rest. It might be the aggressive approach. "Your search is over. I am the person you are looking for', was a widely used trick that occasionally succeeded. Or it might be some special feature specially designed for the job interview.There is no doubt, however, that it is increasing number ofapplicants with university education at all points in the process of engaging staff that has led to the greater importance of the curriculum vitae.57. The new type of advertisement which is appearing in newspaper columns .A) informs job hunters of the opportunities availableB) promises to offer useful advice to those looking for employmentC) divides available jobs into various typesD) informs employers of the people available for work58. Nowadays a demand for this specialized type of service has been created because .A) there is a lack of jobs available for artistic peopleB) there are so many top?level jobs availableC) there are so many people out of workD) the job history is considered to be a work of art59. In the past it was expected that first job hunters would .A) write an initial letter giving their life historyB) pass some exams before applying for a jobC) have no qualifications other than being able to read and writeD) keep any detailed information until they obtained aninterview60. Later, as one went on to apply for more important jobs, one was advised to include in the letter .A) something that would distinguish one from other applicantsB) hinted information about the personality of the applicantC) ones advantages over others in applying for the jobD) an occasional trick with the aggressive approach61. The curriculum vitae has become such an important document because .A) there has been an increase in the number of jobs advertisedB) there has been an increase in the number of applicants with degreesC) jobs are becoming much more complicated nowadaysD) the other processes of applying for jobs are more complicatedPassage TwoQuestions 62 to 66 are based on the following passage.In cities with rent control, the city government sets the maximum rent that a landlord can charge for an apartment. Supporters of rent control argue that it protects people who are living in apartments. Their rent cannot increase; therefore, they are not in danger of losing their homes. However, the critics say that aftera long time, rent control may have negative effects. Landlords know that they cannot increase their profits. Therefore, they invest in other businesses where they can increase their profits. They do not invest in new buildings which would also be rentcontrolled. As a result, new apartments are not built. Many people who need apartments cannot find any. According to the critics, the end result of rent control is a shortage of apartments in the city.Some theorists argue that the minimum wage law can cause problems in the same way. The federal government sets the minimum that an employer must pay workers. The minimum helps people who generally look for unskilled, lowpaying jobs. However, if the minimum is high, employers may hire fewer workers. They will replace workers with machinery. The price, which is the wage that employers must pay, increases. Therefore, other things being equal, the number of workers that employers want decreases. Thus, critics claim, an increase in the minimum wage may cause unemployment. Some poor people may find themselves without jobs instead of with jobs at the minimum wage.Supporters of the minimum wage say that it helps people keep their dignity. Because of the law, workers cannot sell their services for less than the minimum. Furthermore, employers cannot force workers to accept jobs at unfair wages.Economic theory predicts the results of economic decisions such as decisions about farm production, rent control, and the minimum wage.

英语四级阅读模拟题及答案大学英语四级阅读模拟题及答案，祝同学们考试顺利！The 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 giveminimum 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.

大学英语四级阅读模拟练习题附答案It came as something of a surprise when Diana, Princess of Wales, made a trip to Angola in 1997, to support the Red Crosss campaign for a total ban on all anti-personnel landmines. Within hours of arriving in Angola, television screens around the World were filled with images of her comforting victims injured in explosions caused by landmines. I knew the statistics, she said. But putting a face to those figures brought the reality home to me; like When I met Sandra, a 13-year-old girl who had lost her leg, and people like her.The Princess concluded, with a simple message: We must stop landmines. And she used every opportunity during her visit to repeat this message.But, back in London, her views were not shared by some members of the British government, which refused to support a ban on these weapons. Angry politicians launched an, attack on the Princess in the press. They described her as very ill-informed and a loose cannon (乱放炮的人).The Princess responded by brushing aside the criticisms: Thisis a distraction (干扰) we do not need. All Im trying to do is help. Opposition parties, the media and the Public immediately voiced their support for the Princess. To make matters worse for the government, it soon emerged that the Princesss trip had been approved by the Foreign Office, and that she was in fact very well-informed about both the situation in Angola and the British governments policy regarding landmines. The result was a severe embarrassment for the government.To try and limit the damage, the Foreign Secretary, Malcolm Rifkind, claimed that the Princesss views on landmines were not very different from government policy, and that it was working towards a worldwide ban. The Defense Secretary, Michael Portillo, claimed the matter was a misinterpretation or misunderstanding.For the Princess, the trip to this war-torn country was an excellent opportunity to use her popularity to show the world how much destruction and suffering landmines can cause. She said that the experience had also given her the Chance to get closer to people and their problems.26.

A 27. D 28. B 29.A 30. BScratchy throats, stuffy noses and body aches all spell misery, but being able to tell if the cause is a cold or flu (流感) may make a difference in how long the misery lasts.The American Lung Association (ALA) has issued new guidelines on combating colds and the flu, and one of the keys is being ableto quickly tell the two apart. Thats because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come.The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three virusesflu A, B and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine (疫苗), which is, for most people, the best way to fight the flu, according to the ALA.But if the flu does strike, quick action can help. Although the flu and common cold have many similarities, there are some obvious signs to look for.Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms.The ALA notes that it may be particularly difficult to tell wheninfants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms. Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome (综合症)，a rare but serious condition of the liver and central nervous system.There is, of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one.11. According to the author, knowing the cause of the misery will help ________.A) shorten the duration of the illnessB) the patient buy medicine over the counterC) the patient obtain cheaper prescription drugsD) prevent people from catching colds and the flu12. We learn from the passage that ________.A) one doesnt need to take any medicine if he has a cold or the fluB) aspirin should not be included in over-the-counter medicinesfor the fluC) delayed treatment of the flu will harm the liver and central nervous systemD) over-the-counter drugs can be taken to ease the misery caused by a cold or the flu13. According to the passage, to combat the flu effectively, ________.A) one should identify the virus which causes itB) one should consult a doctor as soon as possibleC) one should take medicine upon catching the diseaseD) one should remain alert when the disease is spreading14.
