四级段落匹配题专项训练题附答案四级段落匹配题专项训练题原文You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.A University Degree No Longer Confers Financial Securitylions of school-leavers in the rich world are about to bid a tearful goodbye to their parents and start a new life at university. Some are inspired by a pure love of learning. But most also believe that spending three or four years at university--and accumulating huge debts in the process--will boost their chances of landing a well-paid and secure job.B.Their elders have always told them that education is the best way to equip themselves to thrive in a globalised world. Blue-collar workers will see their jobs outsourced and automated, the familiar argument goes. School dropouts will have to cope with a life of cash-strapped (资金紧张的) insecurity. But the graduate elite will have the world at its feet. There is some evidence to support this view. A recent study from Georgetown Universitys Centre on Education and the Workforce argues that"obtaining a post-secondary credential ( 证书) is almost always worth it." Educational qualifications are tightly correlated with earnings: an American with a professional degree can expect to pocket $3.6m over alifetime; one with merely a high- school diploma can expect only $1.3m. The gap between more- and less-educated earners may be widening. A study in 2002 found that someone with a bachelors degree could expect to earn 75% more over a lifetime than someone with only a high-school diploma. Today the disparity is even greater.C.But is the past a reliable guide to the future? Or are we at the beginning of a new phase in the relationship between jobs and education? There are good reasons for thinking that old patterns are about to change--and that the current recession-driven downturn (衰退) in the demand for Western graduates will morph (改变) into something structural. The strong wind of creative destruction that has shaken so manyblue-collar workers over the past few decades is beginning to shake the cognitive elite as well.D.The supply of university graduates is increasing rapidly. The Chronicle of Higher Education calculates that between 1990 and 2007 the number of students going to university increased by 22% in North America, 74% in Europe, 144% in Latin America and 203% in Asia. In 2007 150m people attended university around the world, including 70m in Asia. Emerging economies—specially China--are pouring resources into building universities that can compete with the elite of America and Europe. They are also producing professional- services firms snch as Tata Consulting Services and Infosys that take fresh graduates and turn them into world-class computer programmers and consultants. The best and the brightest of the rich world must increasingly compete with the best and the brightest from poorer countries who are willing to work harder for less money.E. At the same time, the demand for educated labor is being reconfigured (重新配置) by technology, in much the same way that the demand for agricultural labor was reconfigured in the 19th century and that for factory labor in the 20th. Computers can not only perform repetitive mental tasks much faster than human beings. They can also empower amateurs to do what professionals once did: why hire aflesh-and-blood accountant to complete your tax return when Turbotax (a software package ) will do the job at a fraction of the cost? And the variety of jobs that computers can do is multiplying as programmers teach them to deal with tone and linguistic ambiguity.F.Several economists, including Paul Krugman, have begun to argue that post-industrial societies will be characterized not by a relentless rise in demand for the educated but by a great "hollowing out", as mid-level jobs are destroyed by smart machines and high-level job growth slows. David Autor, of the Massachusetts Institute of Technology (MIT), points out that the main effect of automation in the computer era is not that it destroys blue-collar jobs but that it destroys any job that can be reduced to a routine. Alan Blinder of Princeton University, argues that the jobs graduates have traditionally performed are if anything more "offshorable" than low-wage ones. A plumber or lorry-drivers job cannot be outsourced to India. A computer programmers can.G. A university education is still a prerequisite for entering some of the great industries, such as medicine, law and academia (学术界), that provide secure and well-paying jobs. Over the 20th century these industries did a wonderful job of raising barriers to entry--sometimes for good reasons (nobody wants to be operated on by a barber) and sometimes for self-interested ones. But these industries are beginning to bend theroles. Newspapers are fighting a losing battle with the blogosphere. Universities are replacing tenure-track professors with non-tenured staff. Law firms are contracting out routine work such as"discovery" (digging up documents relevant to a lawsuit) to computerized-search specialists such as Blackstone Discovery. Even doctors are threatened, as patients find advice online and treatment in Walmarts new health centers.H.Thomas Malone of MIT argues that these changes--automation, globalizafion and deregulation--may be part of a bigger change: the application of the division of labor to brain-work. Adam Smiths factory managers broke the production of pins into 18 components. In the same way, companies are increasingly breaking the production of brain-work into ever tinier slices. TopCoder chops up IT projects into bite-sized chunks and then serves them up to a worldwide workforce of freelance coders.I.These changes will undoubtedly improve the productivity ofbrain-workers. They will allow consumers to sidestep (规避 ) the professional industries that have extracted high rents for their services. And they will empower many brain-workers to focus on what they are best at and contract out more tedious tasks to others. But the reconfiguration of brain-work will also make life far less cozy and predictable for the next generation of graduates.四级段落匹配题专项训练题选项46. The creative destruction that has happened to blue-collar workers in the past also starts to affect the cognitive elite.47. For the next generation of graduates, life will be far less comfortable and predictable with brain-work reconfigured.48. After computers are taught by programmers to deal with tone and linguistic ambiguity, the variety of jobs they can do will increase dramatically.49. Most school-leavers believe that, despite the huge debts they owe, going to university will increase their chances of getting secure jobs with high salaries.50. Modern companies are more likely to break the production of intellectual work into ever tinier slices.51. A scholar of Princeton University claims that the jobs traditionally taken by graduates are more likely to be offshored than low-wage ones.52. The income gap between an American professional degree holder and an American high-school graduate shows income is closely related to educational qualifications.53. The changes in the division of brain-work will save consumers some high service fees the professional organizations charge.54. Some students have always been told that. to achieve success ina globalised world, it is most advisable to equip themselves with education.55. Emerging economies are providing a lot of resources to build universities to compete with the elite of America and Europe.四级段落匹配题专项训练题答案46.C解析：题干意为，过去发生在蓝领工人身上的创造性毁灭，现在也开始对文化精英造成影响了。

英语四级段落信息匹配题最详尽解法说明

英语四级段落信息匹配题最详尽解法说明难点分析：1、顺序原则被打破段落细节信息配对题之所以让无数考生闻之色变，主要在于这种题目打破了解答雅思阅读题目传统的阅读技巧和解题思路。

首先，作为匹配题代表，这种题型明显不会遵守其他主流题型的“顺序原则”，考生从*开头到结尾定位的方法显然行不通;2、题目均为长句形式其次，题目当中的表述通常是极其复杂和繁琐的名词短语或者长难句型，在试图寻找合适的定位词之前，考生往往就业已被题干错中复杂的表述搞得云里雾里了;例如四级样卷第51题：The number of foreign students applying to U.S. universities decreased sharply after September 11 due to changes in the visa process.3、定位词模糊即使考生能够排除万难，读懂题目陈述中晦涩难懂的意思，寻找定位词仍然存在很大的障碍，因为这类题目往往不会出现非常明显的可以实践拿来主义的明显定位词(数字、时间、地点、人物、特殊字体和特殊符号等等)，即使侥幸被我们碰到一个，这个定位词也通常和*主题联系密切，且出现多次，所以并没有太大实用意义，例如上题中的U.S.;4、两题对一段的可能性增加干扰性最后，一般选择题至少是一对一进行对应的，如果能够成功选出一对，那么就至少可以排除一个选项。

但是在段落细节信息对应题当中，四六级样卷明确提醒：You may choose a paragraph more than once.一段可能被用两次。

这样最有效的排除法在这里也就再无用武之地了。

所以，从上面四个特点不难看出，如果想从根本上解决这种题型，考试方的思路是希望考生能够从头到尾读完一遍*，从宏观和微观两个方面全面掌握*的结构和细节信息之后再进行解题的，但是这种思路对于阅读水平和单词量都有限的四六级考生来说有些难针对四级样题，我们对四级考生提出以下做题建议：段落信息匹配题的做题攻略一、先看题再看*1、段落细节信息配对题的陈述虽然都是*细节信息，但是表述基本都是围绕*标题或者每一段落的主题进行描述的，通过快速阅读题干部分表述，可以迅速了解*主旨大意。

英语四级长篇阅读匹配试题及答案

英语四级长篇阅读匹配试题及答案英语四级长篇阅读匹配试题及答案 1There are three kinds of goals: short-term,medium-range and long-term goals. Short-range goals are those that usually deal with current activities,which we can apply on a daily basis.Such goals can be achieved in a week or less,or two weeks,or possible months.It should be remembered that just as a building is no stronger than its foundation ,out long-term goals cannot amount to very munch without the achievement of solid short-term goals.Upon completing our short-term goals,we should date the occasion and then add new short-term goals that will build on those that have been completed. The intermediate goals bukld on the foundation of the short-range goals.They might deal with just one term of school or the entire school year,or they could even extend for several years.Any time you move a step at a time,you should never allow yourself to become discouraged or overwhelmed. As you complete each step,you will enforce the belief in your ability to grow adn succeed.And as your list of completion dates grow,your motivation and desire will increase.Long-range goals may be related to our dreams of the future. They might cover five years or more. Life is not a static thing.We should never allow a long-term goal to limit us or our course of action. 1.Our long-term goals mean a lot______.A.if we complete our short-range goalsB.if we cannot reach solid short-term goalsC.if we write down the datesD.if we put forward some plans2.New short-term goals are bulid upon______.A.two yearsB.long-term goalsC.current activitiesD.the goals that have been completed3.When we complete each step of our goals ,______.A.we will win final successB.we are overwhelmedC.we should build up confidence of successD.we should strong desire for setting new goals 4.Once our goals are drawn up,_______.A.we should stick to them until we complete themB.we may change our goals as we have new ideas and opportunitiesC.we had better wait for the exciting news of successD.we have made great decision5.It is implied but not stated in the passage that ______.A.those who habe long-term goals will succeedB.writing down the dates may discourage youC.the goal is only a guide for us to reach our desinationD.every should have a goal答案：adcbc英语四级长篇阅读匹配试题及答案 2If the population of the earth goes on increasing at its present rate, there will eventually not be enough resources left to sustain life on the planet.By the middle of the 21st century,if present trends continue, we will have used up all the oil that drives our cars,for example.Even if scientists develop new ways of feeding the human race,the crowded conditions on earth will make it necessary for lus to look for open space somewhere else. But none of the other planets in our solar system are capable of supporting life at present. One possible solution to the problem, however,has recently been suggested by American scientist, Professor Carl Sagan. Sagan believes that before the earths resources are compleetely exhausted it will be possible to change the atmophere of Venus and so create a new world almost as large as earth itself. The difficult is that Venus is much hotter than the earth and there is only a tiny amount of water there. Sagan proposes that algae organisms that can live in extremely hot or cold atmospheres and at the same time produce oxygen,should be bred in condition similar to those on Venus.As soon as this has been done, the algae will be placed in small rockets. Spaceship will then fly to Venus and fire the rockets into the atmosphere .In a fairly short time, the alge will break down the carbon dioxide into oxygen andcarbon. When the algae have done theri work, the atmosphere will become cooler,but befor man can set foot on Venus it will be neccessary for the oxygen to produce rain. The surface of the planet will still be too hot for man to land on it but the rain will eventually fall and in a few years something like earth will be reproduced on Venus. -1.Inte long run, the most insoluble problem caused by population growth on earth will probably be the lack of ______.a.foodb.oilc.spaced.resources2.Carl Sagan believes that Venus might be colonized from earth because _____ a.it might be possible to change its atmosphere b.its atmosphere is the same as the earthsc.there is a good supply of water on Venusd.the days on Venus are long enough3.On Venus there is a lot of ________.a.waterb.carbon dioxidec.carbon monoxided.oxygen4.Algae are plants that can____.a.live in very hot temperaturesb.live in very cold temperaturesc.manufacture oxygend.all of the above5. Man can land on Venus only when_______. a.the algae have done their work -b.the atmosphere becomes coolerc.thereis oxygend.it rains there答案：cabdd英语四级长篇阅读匹配试题及答案 3Like a needle climbing up a bathroom scale, the number keeps rising. In 1991, 15% of Americans were obese(肥胖的); by 1999, that proportion had grown to 27%. Youngsters, who should have age and activity on their side, are growing larger as well: 19% of Americans under 17 are obese. Waistbands have been popping in other western countries too, as physical activity has declined and diets have expanded. By and large, people in the rich world seem to have lost the fight against flab(松弛).Meanwhile, poorer nations have enjoyed some success in their battles against malnutrition and famine. But, according to research presented at the annual meeting of the American Association for the Advancement of Science, it is more a case of being out of the frying pan and into the fire. The most striking example actually in the poor world comes from the Pacific islands, home of the world’s most obese communities. In 1966, 14% of the men on this island were obese while 100% of men under the age of 30 in 1996 were obese.This increase in weight has been uneven as well as fast. As a result, undernourished and over-nourished people frequently live cheek by jowl(面颊). The mix can even occur within a single household. A study of families in Indonesia found that nearly 10% contained both the hungry and the fat. This is a mysterious phenomenon, but might have something to do with people of different ages being given different amounts of food to eat.The prospect of heading off these problems is bleak. In many affected countries there are cultural factorsto contend with, such as an emphasis on eating large meals together, or on food as a form. ofhospitality.Moreover, there is a good measure of disbelief on the part of policymakers that such a problem Could existin their countries. Add to that reluctance on the part of governments to spend resources on promoting dietand exercise while starvation is still a real threat, and the result is a recipe for inaction. Unless something is done soon, it might not be possible to turn the clock back.英语四级阅读模拟试题：Choose correct answers to the question:1.The first sentence of the passage most probably implies that ______.A.many Americans are obsessed with the rising temperature in their bathroomB.more people are overweighed in the United StatesC.people are doing more physical exercises with the help of scalesD.youngsters become taller and healthier thanks to more activities2.As physical exercise declines and diet expands, ______.A.other western countries has been defeated by fatB.obesity has become an epidemic(流行病)of the rich worldC.waistbands begin to be popular in other western countriesD.western countries can no longer fight against obesity3.Which is NOT the point of the example of the Pacific Islands?A.The poor community has shaken off poverty and people are well-fed now.B.Obesity is becoming a problem in the developing world too.C.Excessive weight increase will cause no less harm than the food shortage.D.The problem of overweight emerges very fast.4.Of tackling obesity in the poor world, we can learn from the passage that____A.the matter is so complex as to go beyond our capacityB.no matter what we do, the prospect will always be bleakC.it is starvation, the real threat, that needs to be solvedD.we should take immediate actions before it becomes incurable5.What is the main idea of this passage?A.Obesity is now a global problem that needs tackling.B.The weights increase fast throughout the whole world.C.Obesity and starvation are two main problems in the poor world.D.Obesity has shifted from the rich world to the poor world.英语四级阅读参考答案1.[B] 推理判断题。

英语四级阅读段落匹配模考试题及答案解析

英语四级阅读段落匹配模考试题及答案解析英语四级阅读段落匹配Jaguars Don't Live Here AnymoreA)Earlier this month, the United States Fish and Wildlife Service announced it would appoint" critical habitat" for the endangered jaguar. Jaguars--the world's third-largest wild cats, weighing up to 250 pounds, with distinctive black rosettes ( 玫瑰花色 ) on their fur--are a separate species from the smaller, tawny (黄褐色的) mountain lions, which still roam large areas of the American West in the United States and take the first steps toward mandating (批准) a jaguar recovery plan. This is a policy reversal and, on the surface, it may appear to be a victory for the conservation community and for jaguars, the largest wild cats in the Western Hemisphere.B) But as someone who has studied jaguars for nearly three decades, I can tell you it is nothing less than a slap in the face to good science. What's more, by changing the rules for animal preservation, it stands to weaken the Endangered Species Act.C)The debate on what to do about jaguars started in 1997, when, at the urging of many biologists ( including me), the Fish and Wildlife Service put the jaguar on the United States endangered species list, because there had been occasional sightings of the cats crossing north over the United States-Mexico border. At the same time, however, the agency ruled that it would not be "prudent" (谨慎的 ) to declare that the jaguar has critical .habitat--a geographic area containing features the species needs to survive--in the United States. Determining an endangered species' critical habitat is a first step toward developing a plan for helping that species recover.D)The 1997 decision not to determine critical habitat for the jaguar was the right one, because even though they cross the border from time to time, jaguars don't occupy any territory in our country--and that probably means the environment here is no longer ideal for them.E)In prehistoric times, these beautiful cats inhabited significant areas of the western United States, but in the past 100 years, there have been few, if any, resident breeding populations here. The last time a female jaguar with a cub ( 幼兽 ) was sighted in this country was in the early 1900s.F)Two well-intentioned conservation advocacy groups, the Center for Biological Diversity and Defenders of Wildlife, sued the Fish and Wildlife Service to change its ruling. Thus in 2006, the agency reassessed the situation and again determined that no areas in the United States met the definition of critical habitat for the jaguar. Despite occasional sightings, mostly within 40 miles of the Mexican border, there were still no data to indicate jaguars had taken up residence inside the United States.G ) After this second ruling was made, an Arizona rancher ( 牧场主 ), with support from the state Game and Fish Department, set infrared-camera (红外摄像机 ) traps togather more data, and essentially confirmed the Fish and Wildlife Service's findings. The cameras did capture transient jaguars, including one male jaguar, nick named Macho, B, who roamed the Arizona borderlands for more than a decade. But Macho B, now dead, might have been the sole resident American jaguar, and his extensive travels indicated he was not having an easy time surviving in this dry, rugged region.H) Despite the continued evidence, the two conservation advocacy groups continued to sue the government. Apparently,they want jaguars to repopulate the United State seven if jaguars don't wan! to. Last March, a federal district judge in Arizona ordered the Fish and Wildlife Service to revisit its 2006 determination on critical habitat.I)The facts haven't changed: there is still no area in the United States essential to the conservation of the jaguar. But, having asserted this twice already, the service, nowunder a new president, has bent to the tiresome litigation (诉讼). On Jan. 12, Fish and Wildlife officials, claimed to have evaluated new scientific information that had become available after the July 2006 ruling. They determined that it is now prudent to appoint critical habitat for the jaguar in the United States.J)This means that Fish and Wildlife must now also formulate a recovery plan for the jaguar. And since jaguars have not been able to reestablish themselves naturally over the past century, the government will likely have to go to significant expense to attempt to bring them back--especially if the cats have to be reintroduced.K)So why not do everything we can, at whatever cost, to bring jaguars back into the United States? To begin with, the American Southwest is, at best, marginal habitat for the animals. More important, there are better ways to help jaguars. South of our border, from Mexico to Argentina, thousands of jaguars live and breed in their true critical habitat. Governments and conservation groups (including the one I head) are already working hard to conserve jaguar populations and connect them to one another through an initiative called the Jaguar Corridor.L).The jaguars that now and then cross into the United States most likely come from the northernmost population of jaguars, in Sonora, Mexico. Rather than demand jaguars return to ourcountry, we should help Mexico and other jaguar-range countries conserve the animals' true habitat itM )The recent move by the Fish and Wildlife Service means that the rare federal funds devoted to protecting wild animals will be wasted on efforts that cannot help save jaguars. It also stands to weaken the Endangered Species Act, because if critical habitat is redefined as any place where a species might ever have existed, and where you or I might want it to exist again, then the door is open for many other sense less efforts to bring back long-lost creatures.N)The Fish and Wildlife officials whose job is to protect the country's wild animals need to grow a stronger backbone--stick with their original, correct decision and save their money for more useful preservation work. Otherwise, when funds are needed to preserve all those small, ugly, non-charismatic endangered species at the back of the line, there may be no money left.1. It is still a fact that there is no suitable place for jaguars to live safely in the United States.2. The United States Fish and Wildlife Service should be more determined and saving for the conservation work.3. Jaguars were regarded as endangered species because of their rare appearance at the United States-Mexico border.4. Money was not spent effectively in helping save jaguars in the recent move by the Fish and Wildlife Service.5. It can be inferred that the United States is not the best choice for jaguars to live from the evidence that they don't settle anywhere here.6. South of the United States' border, from Mexico to Argentina, is the true critical habitat for jaguars.7. The number of jaguars breeding populations in significant areas of the western United States has deceased in the past century.8. It is necessary for the government to invest lots of funds in order to help jaguars to reestablish.9. It didn't indicate that jaguars had settled down in the United States even though they were seen within 40 miles of the Mexican border at times.10. Fish and Wildlife officials were sure enough to appoint critical habitat for the jaguar in the United States.答案解析：1.I)。
