长篇阅读——匹配题Directions: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived.You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questionsby marking the corresponding letter on Answer Sheet 2.Passage 1Paper —More than Meets the EyeA) We are surrounded by so much paper and card that it is easy to forget just how complex it is. There are manyvarieties and grades of paper materials, and whilst it is fairly easy to spot the varieties, it is far more difficult to spot the grades.B) It needs to be understood that most paper and card is manufactured for a specific purpose, so that whilst thecorn-flake packet may look smart, it is clearly not something destined for the archives. It is made to look good, but only needs a limited life span. It is also much cheaper to manufacture than high grade card.C) Paper can be made from an almost endless variety of cellulose(纤维素化合物)-based material which will includemany woods, cottons and grasses of which papyrus is an example and from where we get the word "paper". Many of these are very specialized, but the preponderance of paper making has been from soft wood and cotton or rags, with the bulk being wood-based.Paper from WoodD) In order to make wood into paper it needs to be broken down into fine strands. Firstly by powerful machinery andthen boiled with strong alkalies(碱) such as caustic soda, until a fine pulp of cellulose fibers is produced. It is from this pulp that the final product is made, relying on the bonding together of the cellulose into layers. That, in a very small nutshell, is the essence of paper making from wood. However, the reality is rather more complicated. In order to give us our white paper and card, the makers will add bleach and other materials such as china clay and additional chemicals.E) A further problem with wood is that it contains a material that is not cellulose. Something called lignin. This isessential for the tree since it holds the cellulose fibres together, but if it is incorporated into the manufactured paper it presents archivists with a problem. Lignin eventually breaks down and releases acid products into the paper. This will weaken the bond between the cellulose fibers and the paper will become brittle and look rather brown and careworn. We have all seen this in old newspapers and cheap paperback books. It has been estimated that most paperback books will have a life of no greater than fifty years, not what we need for our archives.F) Since the lignin can be removed from the paper pulp during manufacture, the obvious question is "why is it left inthe paper". The answer lies in the fact that lignin makes up a considerable part of the tree. By leaving the lignin in the pulp a papermaker can increase his paper yield from a tree to some 95%. Removing it means a yield of only 35%. It is clearly uneconomic to remove the lignin for many paper and card applications. It also means, of course, that lignin-free paper is going to be more expensive.G) However, it is nevertheless what the archivist must look for in his supplies. There is no point whatsoever incarefully placing our valuable artifacts in paper or card that is going to hasten their demise. Acid is particularly harmful to photographic materials, causing them to fade and in some cases simply vanish!H) So, how do we tell a piece of suitable paper or card from one that is unsuitable? You cannot do it by simply looking,and rather disappointingly, you cannot always rely on the label. "Acid-free" might be true inasmuch as a test on the paper may indicate that it is a neutral material at this time. But lignin can take years before it starts the inevitable process of breaking down, and in the right conditions it will speed up enormously.I) Added to this, as I have indicated earlier, paper may also contain other materials added during manufacture such asbleach, china clay, chemical whiteners and size. This looks like a bleak picture, and it would be but for the fact that there are suppliers who will guarantee the material that they sell. If you want to be absolutely sure that you are storing in, or printing on, the correct material then this is probably the only way.J) Incidentally, acids can migrate from material to material. Lining old shoe boxes with good quality acid-free paper will do little to guard the contents. The acid will get there in the end.Paper from RagK) Paper is also commonly made from cotton and rag waste. This has the advantage of being lignin-free, but because there is much less cotton and rag than trees, it also tends to be much more expensive than wood pulp paper. You will still need to purchase from a reliable source though, since even rag paper and card can contain undesirable additives.L) A reliable source for quality rag papers is a recognized art stockiest. Many water color artists insist on using onlyfine quality rag paper and board.M) The main lesson to learn from this information is that you cannot rely on purchasing archival materials from the high street. The only safe solution is to purchase from specialist suppliers. It may cost rather more, but in the end you will know that your important and valuable data and images have the best home possible.1. The corn-flake packet is cheaper than high grade card.2. There are a lot of materials which can be used for making paper, but the superior ones are soft wood, cotton and rags.3. During the whole manufacturing process, the final product is made from a pulp of cellulose fibres.4. In order to make white paper and card, the makers will add bleach.5. Lignin is essential for the tree but it will make paper easy to break.6. Many paper producers will preserve lignin during manufacture, because leaving the lignin will make more paper from a tree.7. Acid is particularly harmful to photographic materials.8. If the lignin is removed from the paper, the paper will be more expensive.9. Although free of lignin, paper made from cotton and rag waste can also cost more money than wood pulp paper because there is much less cotton and rag than trees.10. What we can learn from “Paper from Rag” is that you had better buy archival materials from specialist suppliers.文章精要:本文主要介绍了我们平常所见所用的纸的复杂性,通过介绍用木头和破布料造纸的过程,使我们对纸的类别、属性有了更深入的了解。
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.

(一).The Touch-Screen GenerationA.On a chilly day last spring, a few dozen developers of children's apps (应用程序) for phones andtablets (平板电脑) gathered at an old beach resort in Monterey, California, to show off their games.The gathering was organized by Warren .Buckleitner, a longtime reviewer of interactive children'smedia. Buckleitner spent the breaks testing whether his own remote-control helicopter could reachthe hall's .second story, while various children who had come with their parents looked up in awe(敬畏) and delight. But mostly they looked down, at the iPads and other tablets displayed around thehall like so many open boxes of candy. I walked around and talked with developers, and severalquoted a famous saying of Maria Montessori's, "The hands are the instruments of man's intelligence."B. What, really, would Maria Montessori have made of this scene? The 30 or so children here were notdown at the shore poking (戳) their fingers in the sand or running them along stones or pickingseashells. Instead they were all inside, alone or in groups of two or three, their faces a few inchesfrom a screen, their hands doing things Montessori surely did not imagine.C. In 2011, the American Academy of Pediatrics updated .its policy on very young children and media- In1999, the group had discouraged television viewing for children younger than 2, citing research onbrain development that showed this age group's critical need for "direct interactions with parents andother significant care givers." The updated report began by acknowledging that things had changedsignificantly since then. In 2006, 90% of parents said that their children younger than 2 consumedsome form of electronic media. Nevertheless, the group took largely the same approach it did in1999, uniformly discouraging passive media use, on any type of screen, for these kids. (For olderchildren, the academy noted,"high-quality programs" could have"'educational benefits.") The 2011report nentioned"smart cell phone" and"new screen" technologies, but did not address interactive- apps. Nor did it bring up the possibility that has likely occurred to those 90% of American parentsthat some good might come from those little swiping (在电子产品上刷) fingers.D. I had come to the developers' conference partly because I hoped that this particular set of parents,enthusiastic as they were about interactive media, might help me out of this problem, that they mightoffer some guiding principle for American parents who are clearly never going to meet the academy'sideals, and at some level do not want to. Perhaps this group would be able to express clearly some benefits of the new technology that the more cautious doctors weren't ready to address.E. I fell into conversation with a woman who had helped develop Montessori Letter Sounds, an app thatteaches preschoolers the Montessori methods of spelling. She was a former Montessori teacher and amother of four. I myself have three children Who are all fans of the touch screen. What games didher kids like to play, I asked, hoping for suggestions I could take home."They don't play all that much."Really? Why not?"Because I don't allow it. We have a rule of no screen time during the week, unlessit's clearlyeducational."No screen time? None at all? That seems at the outer edge of restrictive, even by the standards ofovercontrolling parents."On the weekends, they can play. I give them a limit of half an hour and then stop. Enough."F. Her answer so surprised me that I decided to ask some of the other developers who were alsoparents what their domestic ground rules for screen time were. One said only on airplanes and longcar rides. Another said Wednesdays and weekends, for half an hour. The most permissive said halfan hour a day, which was about my rule at home. At one poing I sat with one of the biggestdevelopers of e-book apps for kids, and his family. The small kid was starting to fuss in her highchair, so the morn stuck an iPad in front of her and played a short movie so everyone else couldenjoy their lunch. When she saw me watching, she gave me the universal tense look of mothers whofeel they are being judged. "At home," she assured me, "I only let her watch movies in Spanish."G. By their reactions, these parents made me understand the problem of our age: as technology becomesalmost everywhere in our lives, American parents are becoming more, not less, distrustful of what itmight be doing to their children. Technological ability has not, for parents, translated into comfortand ease. On the one hand, parents want their children to swim expertly in the digital s~ream thatthey will have to navigate (航行) all their lives; on the other hand, they fear that too much digitalmedia, too early, will sink them. Parents end up treating tablets as precision surgical (外科的)instruments, devices that might perform miracles for their child's IQ and help him win some greatrobotics competitionbut only if they are used just so. Otherwise, their child could end up one of~ those sad, pale creatures who can't make eye contact and has a girlfriend who lives only in thevirtual world.H. Norman Rockwell, a 20th-century artist, never painted Boy Swiping Finger on Screen, and our ownvision of a perfect childhood has never been adjusted to accommodate that now-common scene. Addto that our modern fear that every parenting decision may have lasting consequences--that everyminute of enrichment lost or mindless entertainment indulged (放纵的) will add up to somepermanent handicap (障碍) in the futureand you have deep guilt and confusion. To date, no bodyof research has proved that the iPad will make your preschooler smarter or teach her to speakChinese, or alternatively that it will rust her nervous system--the device has been out for only threeyears, not much more than the time it takes some academics to find funding and gather researchsubjects. So what m a parent to do?注意:此部分试题请在答题卡2上作答.46. The author attended the conference, hoping to find some guiding principles for parenting in theelectronic age.47. American parents are becoming more doubtful about the benefits technology is said to bring to theirchildren.48. Some experts believe that human intelligence develops by the use of hands.49. The author found a former Montessori teacher exercising strict control over her kids' screen time.50. Research shows interaction with people is key to babies' brain development.51. So far there has been no scientific proof of the educational benefits of iPads.52. American parents worry that overuse of tablets will create problems with their kids' interpersonalrelationships.53. The author expected developers of children's apps tospecify the benefits of the new technology.54. The kids at the gathering were more fascinated by the iPads than by the helicopter.55. The author permits her children to use the screen for at most half an hour a day.Section C触屏一代A)在去年一个寒冷的春日,几十家研发手机及平板电脑儿童应用程序的开发商聚集在加州蒙特利的一个旧海滨度假村,展示他们的游戏应用。

Section BDirections:In this section,you are going to read a passage with ten statements attached to it.Each smtement contains information given in one of the paragraphs.1ndentify the paragraph from which the information is derived.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.Creative Book Report Ideas A.Are you at a loss for creative book report ideas for your students?If yes.then this article will help you make reading and reviewing books more creative for your class.In an age of PSPs,Xbox,anime and gaming arcades,reading has lost its foothold in the list of hobbies that children tend to cite.Most of the reading that kids do today,comes in the form of compulsory books that they need to read for school and maybe that is the reason they find reading to be an insurmountable and boring task.If you want to inculcate the love for languages and literary masterpieces in your students and want them to devour books everyone should read,then a good way of going about the same would be to get them to start working on creative book report ideas.While working on creative ideas for book reports,your students will have to understand the book in a way that allows them to come up with new ways to present to the class,the essence of the book.B.As a teachel while egging your students to activate their creative gray cells.you will have to help them out with basic ideas that they can work on.Depending on the age bracket that your students belong to,the creative book report ideas will vary.This is so,not just because of the varying attention spans that children of various age groups posses but also because of the amount of work that kids can put into the report.While a middle school student wiIl be comfortable handling a handy cam,a student from elementary school will be more fascinated if he is working with paints and puppets.So do you want to know how to write a book report creatively?In this article.we will list out for you,a couple of good creative book report ideas for elementary students and for middle school students.C.A book report sandwich is a good creative idea for book reports.As a teacher you can get drawings of a sandwich on sheets of Paper that are of the color of the ingredients of your sandwich,for example,a cream sheet of paper to resemble mayonnaise,red to represent tomato and likewise.Ob.viously,each ingredient should be cut in a way that when assembled together,it looks like a sandwich.Now,give each of your students one of these book sandwiches to create their book report.It can start with the name of the book and the author’s name on the top slice of the sandwich.The second ingredient can have the summary of the book on it.Each subsequent ingredient can have a description of the main characters,the setting of the book,the plot,and then his or her views about the book.Once they are done with their book reports,they can staple the book sandwich together and then,you can create a class bulletin board with all the book report sandwiches on display.D.One of the good techniques to retell a story,it is also one of the favorite creative book report ideas among students.The job that the student will have is to read the book and then pick a few objects at his/her home which will allow him/her to retell the story in a way that makes it interesting for his/ her audience.Every time he/she picks out an object from the bag to report the book he/she has read,there has to be a valid connection between the book and the object,which the student can first ask the audience to guess and then go ahead and explain it.This idea is spin—off on the normal show and tells and allows for an interactive book report session.E.This is one of the creative ideas for book reports in which.as the teacher, you will have to divideyour class into groups and give them one book each.The students can then read the book and get together and write a play and act it out for the class.To give a deeper insight into the book,one of the students can play the role of the author and as a group,the students can try and recreate the thought Drocess of the author.The student playing the role of the author can then interrupt the play at lmportant iunctllres and talk about the reasons for these twists in the play and how he/she came up with these plot lines.F.As a voung adult,your student’s fascination may go beyond the immediate concerns of the book.He/she may want to understand the circumstances in which the book was written,the times then,the events happening in the world and get the author’s perspective about the book.Encourage your students to mink on those lines.Divide the class into pairs and give each pair one book to read.Let them then do the roles of the author and a journalist.You can have an interview session in front of the class.enabling them todissect the book and get a peek into the author’s world.G.In a technology—obsessed world,it maybe a very tiny minority of your class that does not get excited with the Drospect of shooting a film.One of the best creative book report ideas for middle school,you will need to divide the class into groups and give them at least two months to adapt the book that thev have been assigned,into a film.The movie should have a well—adapted screenplay,and allother prerequisites,like a lighting engineer,sound engineer, costume designer,etc.At the end of the given time,the film can be screened in front of the class and then discussed.H.If you are on the lookout for good individual creative book report ideas,then this one could be for you.Assign every student a book and then ask them to start maintaining a diary,from the author’sDoint of vie w.Ask them to come up with imaginary incidents from the author’s life and use historical events to explain why the author wrote the book in a certain manner.Alternately, you can also ask your students to give a surrogate ending to the story.I)、These are just few of the options that you could use to inspire your students to come up with creative book report ideas.As kids we tend to be more imaginative and creative .Encourage your students to mink om of the box and appreciate them for their efforts.This will help you have a class that is not only lively and inquisitive by nature but also a class that will cultivate a love for words.46.11eachers can create a class bulletin board to display all the book report sandwiches after their students finish their reports.47.Adopting the method of knowing your author,teachers can encourage students to think beyond the immediate concerns of the book.48.Asking me students to write from their own point of view is suitable for teachers who are on the lookout for good individual creative book report ideas.49.Retelling a story is one of the favorite creative book report ideas among students and it tells and allows for an interactive book report session.50.Nowadays,most of book children read are those they need to read for school.51.Teachers tend to be more imaginative and creative as kids.52.While working on creative ideas for book reports,students will have to understand the book.53.The creative book report ideas vary according to ages because children in different age groups have different attention span.54.If teachers ask their students to shoot a film about a book,they should give them no fewer than two months.55.Teachers have to divide their class into groups and give them one book each is a good creative book report ideas.46.Teachers can create a class bulletin board to display all the book report sandwiches after their students finish their reports.在学生完成他们的读书报告后,老师可以设立一个班级布告板,把所有的三明治读书报告展示出来。

Identify the paragraph from which the information is derived. 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.Can Burglars Jam Your Wireless Security System?[A]Any product that promises to protect your home deserves careful examination. So it isn’t surprising that you’ll find plenty of strong opinions about the potential vulnerabilities of popular home-security systems.[B]The most likely type of burglary (入室盗窃) by far is the unsophisticated crime of opportunity, usually involving a broken window or some forced entry. According to the FBI, crimes like these accounted roughly two-thirds of all household burglaries in the US in 2013.The wide majority of the rest were illegal, unforced entries that resulted from something like a window being left open. The odds of a criminal using technical means to bypass a security system are so small that the FBI doesn’t even track those statistics.[C]One of the main theoretical home-security concerns iswhether or not a given system is vulnerable to being blocked from working altogether. With wired setups, the fear is that a burglar (入室盗贼) might be able to shut your system down simply by cutting the right cable. With a wireless setup, you stick battery-powered sensors up around your home that keep an eye on windows, doors, motion, and more. If they detect something wrong w hile the system is armed, they’ll transmit a wireless alert signal to a base station that will then raise the alarm. That approach will eliminate most cord-cutting concerns—but what about their wireless equivalent, jamming? With the right device tuned to t he right frequency, what’s to stop a thief from jamming your setup and blocking that alert signal from ever reaching the base station?[D]Jamming concerns are nothing new, and they’re not unique to security systems. Any device that’s built to receive a wireless signal at a specific frequency can be overwhelmed by a stronger signal coming in on the same frequency. For comparison, let’s say you wanted to “jam” a conversation between two people—all you’d need to do is yell in the listener’s ear.[E] Security devices are required to list the frequencies they broadcast on—that means that a potential thief can find what they need to know with minimal Googling. They will, however, need so know what system they’re looking for. If you have a sign in your yard declari ng what setup you use, that’d point them in the right direction, though at that point, we’re talking about a highly targeted, semi-sophisticated attack, and not the sort forced-entry attack that makes up the majority of burglaries. It’s easier to find and acquire jamming equipment for some frequencies than it is for others.[F] Wireless security providers will often take steps to helpcombat the threat of jamming attacks. SimpliSafe, winner of our Editor’s Choice distinction, utilizes a special system that’s capable of separating incidental RF interference from targeted jamming attacks. When the system thinks it’s being jammed, it’ll notify you via push alert(推送警报).From there, it’s up to you to sound the alarm manually.[G] SimpliSafe was singled out in one recent article on jamming, complete with a video showing the entire system being effectively bypassed with handheld jamming equipment. After taking appropriate measures to contain the RF interference to our test lab, we tested the attack out for ourselves, and were able to verify that it’s possible with the right equipment. However, we also verified that SimpliSafe’s anti-jamming system works. It caught us in the act, sent an alert to my smartphone, and also listed our RF interference on the system’s event log. The team behind the article and video in question make no mention of the system, or whether or not in detected them.[H]We like the unique nature of that software. It means that a thief likely wouldn’t be able to Google how the system works, then figure out a way around it. Even if they could, SimpliSafe claims that its system is always evolving, and that it varies slightly from system to system, which means there wouldn’t be a universal magic formula for cracking it. Other systems also seem confident on the subject of jamming. The team at Frontpoint addresses the issue in a blog on its site, citing their own jam protection software and claiming that there aren’t any documented cases of successful jam attack since the company began offering wireless security sensors in the 1980s.[I] Jamming attacks are absolutely possible. As said before, with the right equipment and the right know-how, it’s possibleto jam any wireless transmission. But how probable is it that someone will successfully jam their way into your home and steal your stuff?[J] Let’s imagine that you live in a small home with a wireless security setup that offers a functional anti-jamming system. First, a thief is going to need to target your home, specifically. Then, he’s going to need to k now the technical details of your system and acquire the specific equipment necessary for jamming your specific setup. Presumably, you keep your doors locked at night and while you’re away. So the thief will still need to break in. That means defeating the lock somehow, or breaking a window. He’ll need to be jamming you at this point, as a broken window or opened door would normally release the alarm. So, too, would the motion detectors in your home, so the thief will need to continue jamming once he’s insi de and searching for things to steal. However, he’ll need to do so without tripping the anti-jamming system, the details of which he almost certainly does now have access to.[K]At the end of the day, these kinds of systems are primarily designed to protect against the sort of opportunistic smash-and-grab attack that makes up the majority of burglaries. They’re also only a single layer in what should ideally be a many-sided approach to securing your home, one that includes common sense things like sound locks and proper exterior lighting at night. No system is impenetrable, and none can promise to eliminate the worst case completely. Every one of them has vulnerabilities that a knowledgeable thief could theoretically exploit. A good system is one that keeps that worst-case setting as improbable as possible while also offering strong protection in the event of a less-extraordinary attack.36. It is possible for burglars to make jamming attacks with the necessary equipment and skill.37. Interfering with a wireless security system is similar to interfering with a conversation.38. A burglar has to continuously jam the wireless security device to avoid triggering the alarm, both inside and outside the house.39. SimpliSafe provides devices that are able to distinguish incidental radio interference from targeted jamming attacks.40. Only a very small proportion of burglaries are committed by technical means.41. It is difficult to crack SimpliSafe as its system keeps changing.42. Wireless devices will transmit signals so as to activate the alarm once something wrong is detected.43. Different measures should be taken to protect one’s home from burglary in addition to the wireless security system.44. SimpliSafe’s device can send a warning to the house owner’s cellphone.45. Burglars can easily get a security device’s frequency by Internet search.【段落匹配答案】Section B36. [I]37. [D]38. [J]39. [F]40. [B]41. [H]42. [C]43. [K]44. [G]45. [E]【解析】36.

文章精要:
本文主要介绍了我们平常所见所用的纸的复杂性,通过介绍用木头和破布料造纸的过程,使我们对纸的类别、属性有了更深入的了解。
答案详解:
根据题干中的信息提示词corn—flakepacket,highgradecard,可定位到文章第二段,该部分最后提到corn-flakepacket在制造过程中比高等级的纸(highgradecard)便宜.
根据题干中的信息提示词softwood,cottonandrags,可定位到文章第三段最后一句。
根据题干中的信息提示词finalproduct,可将答案定位到D段,第二、三句提到最后的产品来源于纤维素纸浆。
根据题干中的信息提示词whitepaperandcard,可将答案定位到D段,该部分最后提到为了得到白纸,纸张生产者在制造过程中添加了漂白粉和其他化学物质。
根据题干中的信息提示词essentialforthetree,可将答案定位到E段,该部分提到木质素是木头的主要组成物,其作用是凝聚纤维素,但它会使纸张变得易碎。
根据题干中的信息提示词lignin,可将答案定位到F段,该部分最后提到许多纸张生产者在生产过程中会保留木质素,主要是因为它会增加树木的造纸产量。
根据题干中的信息提示词acid,可将答案定位到G段,该部分最后提到酸对相纸
的原料尤其不利。
根据题干中的信息提示词lignin和paper可定位到文章的F段,因为该段提到,如果在纸张的生产中去除木质素,将会降低树木出产纸张的量,由此可以知道,去除了木质素的纸张价格必定会更加昂贵。
根据题干中的信息提示词cottonandragwaste可定位到文章的K段,该部分告诉我们,尽管用棉花和破布料造的纸里没有木质素,但它们要比木制的纸贵很多,这是因为棉花和破布料的数量比树木少得多,由此可以得出答案。
根据题干中的信息提示词PaperfromRa9可定位到文章的最后一段,该部分提出最好到专业的供应商那里去买档案材料,由此可以得出答案。
