四级阅读段落信息匹配题技巧及练习

段落信息匹配题1.这种题型可以放到最后做。

2.考生难以按照阅读题一贯遵循的“顺序原则”解题。

细节信息的排列绝对是“乱序的”，这就意味着从文章开头到结尾按顺序定位的方法是行不通的。

3.快速掌握文章脉络。

通过阅读中心句快速掌握文章脉络。

中心句一般出现在：1）首句；2）转折词如but ；3）因果关系联接词如as a result 引领的第二句；4）问句后面的答句。

在找到中心句后，读一下末句，可以更精确地掌控段意。

若无特别明显的中心句，首尾句的阅读也有助于理解段意。

阅读过程当中，有的信息点明确可直接先去选出答案。

这里我们也要明确要多看外文，掌握外文的行文思路。

4.一般而言文章组织有三大类。

一是按时间，如货物运输，这是最简单的。

二是按观点—原因—发展—瓶颈—措施—目标的布局来分析一件事物。

三是偏科普的夹杂很多不同派别的理论，这个相对而言比较难。

5.划出句子中的关键词。

由于人的短期记忆能力是有限的，在短时间内无法记下所有的句子。

因此需要寻找选项中的一些在最大程度上概括整个选项的关键词。

带着这些关键词去浏览全篇文章，找到它们所涉及的相关内容后，再研读细节，最终确定此句是否和该段匹配。

6.题干提供的信息表述中通常会出现一些具有特殊意义的指示性词汇，这类词汇虽然不是通常意义上的定位关键词，但其特殊含义可将考生的注意力指向原文的开头、结尾或是某个具有特殊特征的段落。

这些词通常包括如下三类：①能够指示开头段的词汇(如overview、introduction、initiation、main idea、definition等)；②能够指示结尾段的词(如overview、future、solution、conclusion、suggestion、summary等)；③能够帮助考生回原文定位的特殊词汇(如rate、ratio、proportion、percentage等词往往对应含“%”的段落；number、figure、statistical demographics等词往往对应数字集中的段落；financial、income、revenue、salary等词往往对应含诸如“$”“￥”等货币符号的段落)。

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

四级长篇阅读段落信息匹配题及答案解析(8)导读：本文四级长篇阅读段落信息匹配题及答案解析(8)，仅供参考，如果觉得很不错，欢迎点评和分享。

Section BDirections: 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 questions by marking the corresponding letter on Answer Sheet 2.A Grassroots RemedyA) Most of us spend our lives seeking the natural world. To this end, we walk the dog, play golf, go fishing, sit in the garden, drink outside rather than inside the pub, have a picnic, live in the suburbs, go to the seaside, buy a weekend place in the country. The most popular leisure activity in Britain is going for a walk. And when joggers (慢跑者) jog, they don't run the streets. Every one of the minstinctively heads to the park or the river. It is my profound belief that not only do we all need nature, but we all seek nature, whether we know we are doing so or not.B) But despite this, our children are growing up nature-deprived ( 丧失) , I spent my boyhood climbing trees on Stratham Common, south London. These days, children are robbed of these an cientfreedoms, due to problems like crime, traffic, the loss of the open spaces and odd new perceptions about what is best for children, that is to say, things that can be bought, rather than things that can be found.C) The truth is to be found elsewhere. A study in the U.S. families had moved to better housing and the children were assessed for ADHD --attention deficit hyperactivity disorder ( 多动症) .Those whose accommodation had more natural views showed an improvement of 19%; those who had the same improvement in material surroundings but no nice view improved just 4%.D) A study in Sweden indicated that kindergarten children who could play in a natural environment had less illness and greater physical ability than children used only to a normal playground. A U.S. study suggested that when a school gave children access to a natural environment, academic levels were raised across the entire school.E) Another study found that children play differently in a natural environment. In playgrounds, children create a hierarchy (等级) based on physical abilities, with the tough ones taking the lead. But when a grassy area was planted with bushes, the children got much more into fantasy play, and the social hierarchy was now based on imagination and creativity.F) Most bullying (持枪凌弱) is found in schools where there is a tarmac (柏油碎石) play ground; the least bullying is in a natural area that the children are encouraged to explore. This reminds mean pleasantly of Sunny hill School in Stratham, with its harsh tarmac, where I used to hang about incomers fantasizing about wildlife. The children are frequently discouraged from involvement with natural spaces, for health and safety reasons, for fear that they might get dirty or that they might cause damage. So, instead, the damage is done to the children themselves: not to their bodies but to their souls.G) One of the great problems of modem childhood is ADHD, now increasingly and expensively treated with drugs. Yet one study after another indicates that contact with nature gives huge benefits to ADHD children. However, we spend money on drugs rather than on green places.H) The life of old people is measurably better when they have access to nature. The increasing emphasis for the growing population of old people is in quality rather than quantity of years. And study after study finds that a garden is the single most important thing in finding that quality.I) In wider and more difficult areas of life, there is evidence to indicate that natural surroundingsim prove all kinds of things. Even problems with crime and aggressive behavior are reduced when there is contact with the natural world. Dr. William Bird, researcher from the Royal Society for the Protection of birds, states in his study, "A natural environment can reduce violent behavior because its restorative process helps reduce anger and impulsive behavior." Wild places need encouraging for this reason, no matter how small their contribution.J) We tend to look on nature conservation as some kind of favor that human beings are granting to the natural world. The error here is far too deep: not only do humans need nature for themselves, but the very idea that humanity and the natural world are separable things is profoundly damaging. Human beings are a species of mammals (哺乳动物) . For seven million years they lived on the planet as part of nature. Our ancestral selves miss the natural world and long for contact with nonhuman life. Anyone who has patted a dog, stoked a cat, sat under a tree with a pint of beer, given or received a bunch of flowers or chosen to walk through the parkon a nice day, understands that. We need the wild world. It is essential to our well-being, our health, our happiness. Without the wild world we are not more but less civilized. Without other living things around us we are less than human.K) Five Ways to Find Harmony with the Natural World Walk: Break the rhythm of permanently being under a roof. Get off a stop earlier, make a circuit of the park at lunchtime, walk the child to and from school, get a dog, feel yourself moving in moving air, look, listen, absorb.Sit: Take a moment, every now and then, to be still in an open space. In the garden, anywhere that's not in the office, anywhere out of the house, away from the routine. Sit under a tree, look at water, feel refreshed, ever so slightly renewed.Drink: The best way to enjoy the natural world is by oneself; the second best way is in company. Take a drink outside with a good person, a good gathering: talk with the sun and the wind with bird-song for background.Learn: Expand your boundaries. Leam five species of bird, five butterflies, five trees, five bird songs. That way, you see and hear more: and your mind responds gratefully to the greater amount of wildness in your life.Travel: The places you always wanted to visit: by the seaside, in the country, in the hills. Take a week-end break, a day-trip, get out these and do it: for the scenery, for the way through the woods, for the birds, for the bees. Go somewhere special and bring specialness home. It lasts forever, after all.46. The study in Sweden shows that more access to nature makes children less likely to fall ill.47. The author's profound belief is that people instinctively seek nature indifferent ways.48. It can be very helpful to provide more green spaces for children with ADHD.49. Elderly people will enjoy a life of better quality when they contact more with nature.50. Nowadays, people think things that can be bought are best for children, rather than things that can be found.51. Dr. William Bird suggests in his study that access to nature contributes to the reduction of violence.52. According to a study in the U. S. Children with ADHD whose accommodation had more natural views showed much better improvement.53. Children who have chances to explore natural areas are less likely to be involved in bullying.54. We can find harmony with the natural world in various ways, among which there are walking,sitting, drinking, learning and traveling.55. It is extremely harmful to think that humanity and the natural world can be separated.Section B大自然疗法A)【47】我们中的大多数人都套花时间寻求与大自然亲近。

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。

英语四级段落信息匹配题及答案

英语四级段落信息匹配题练习及答案

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.长篇阅读Beauty and Body Image in the Media[A] Images of female bodies are everywhere. Women—and their body parts—sell everything from food to cars. Popular film and television actresses are becoming younger, taller and thinner. Some have even been known to faint on the set from lack of food. Women’s magazines are full of articles urging that if they can just lose those last twenty pounds, they’ll have it all—the perfect marriage, loving children, great sex, and a rewarding career.[B] Why are standards of beauty being imposed on women, the majority of whom are naturally larger and more mature than any of the models? The roots, some analysts say, are economic. By presenting an ideal difficult to achieve and maintain the cosmetic and diet product industries are assured of growth and profits. And it’s no accident that youth is increasingly promoted, along with thinness, as an essential criterion of beauty. If not all women need to lose weight, for sure they’re all aging, says the Quebec Action Network for Women’s Health in its 2001 report. And, according to the industry, age is a disaster that needs to be dealt with.[C] The stakes are huge. On the one hand, women who are insecure about their bodies are more likely to buy beauty products, new clothes, and diet aids. It is estimated that the diet industry alone is worth anywhere between 40 to 100 billion (U.S.) a year selling temporary weight loss (90% to 95% of dieters regain the lost weight). On the other hand, research indicates that exposure to images of thin, young, air-brushed female bodies is linked to depression, loss of self-esteem and the development of unhealthy eating habits in women and girls.[D ] The American research group Anorexia Nervosa & Related Eating Disorders, Inc. says that one out of every four college-aged women uses unhealthy methods of weight control—including fasting, skipping meals, excessive exercise, laxative (泻药)abuse, and self-induced vomiting. The pressure to be thin is also affecting young girls: the Canadian Women’s Health Network warns that weight control measures are now being taken by girls as young as 5 and 6. American statistics are similar. Several studies, such as one conducted by Marika Tiggemann and Levina Clark in 2006 titled “Appearance Culture in 9- to 12-Year-Old Girls: Media and Peer Influences on Body Dissatisfaction,” indicate that nearly half of all preadolescent girls wish to be thinner, and as a result have engaged in a diet or are aware of the concept of dieting. In 2003, Teen magazine reported that 35 percent of girls 6 to 12 years old have been on at least one diet, and that 50 to 70 percent of normal weight girls believe they are overweight. Overall research indicates that 90% of women are dissatisfied with their appearance in some way. Media activist Jean Kilbourne concludes that, “Women are sold to the diet industry by the magazines we read and the television programs we watch, almost all of which make us feel anxious about our weight.”[ E] Perhaps the most disturbing is the fact that media images of female beauty are unattainable for all but a very small number of women. Researchers generating a computer model of a woman with Barbie-doll proportions, for example, found that her back would be too weak to support the weight of her upper body, and her body would be too narrow to contain more than half a liver and a few centimeters of bowel. A real woman built that way would suffer from chronic diarrhea (慢性腹泻)and eventually die from malnutrition. Jill Barad, President of Mattel (which manufactures Barbie), estimated that 99% of girls aged 3 to 10 years old own at least one Barbie doll. Still, the number of real life women and girls who seek a similarly underweight body is epidemic, and they can suffer equally devastating health consequences. In 2006 it was estimated that up to 450, 000 Canadian women were affected by an eating disorder.[F ] Researchers report that women’s magazines have ten and one-half times more ads and art icles promoting weight loss than men’s magazines do, and over three-quarters of the covers of women’s magazines include at least one message about how to change a woman’s bodily appearance—by diet, exercise or cosmetic surgery. Television and movies reinforce theimportance of a thin body as a measure of a woman’s worth. Canadian researcher Gregory Fouts reports that over three-quarters of the female characters in TV situation comedies are underweight, and only one in twenty are above average in size. Heavier actresses tend to receive negative comments from male characters about their bodies (“How about wearing a sack?，，)，and 80 percent of these negative comments are followed by canned audience laughter.[G] There have been efforts in the magazine industry to buck (才氐制，反抗)the trend. For several years the Quebec magazine Coup de Pouce has consistently included full-sized women in their fashion pages and Chatelaine has pledged not to touch up photos and not to include models less than 25 years of age. In Madr id, one of the world’s biggest fashion capitals, ultra-thin models were banned from the runway in 2006. Furthermore Spain has recently undergone a project with the aim to standardize clothing sizes through using a unique process in which a laser beam is us ed to measure real life women’s bodies in order to find the most true to life measurement.[ H] Another issue is the representation of ethnically diverse women in the media. A 2008 study conducted by Juanita Covert and Travis Dixon titled “A Changing Vie w: Representation and Effects of the Portrayal of Women of Color in Mainstream Women’s Magazines” found that although there was an increase in the representation of women of colour, overall white women were overrepresented in mainstream women’s magazines f rom 1999 to 2004.[I] The barrage of messages about thinness, dieting and beauty tells “ordinary” women that they are always in need of adjustment—and that the female body is an object to be perfected. Jean Kilbourne argues that the overwhelming presence of media images of painfully thin women means that real women’s bodies have become invisible in the mass media. The real tragedy, Kilbourne concludes, is that many women internalize thesestereotypes, and judge themselves by the beauty industry’s standa rds. Women learn to compare themselves toother women, and to compete with them for male attention. This focus on beauty and desirability “effectively destroys any awareness and action that might help to change that climate.”46. A report in Teen magazine showed that 50% to 70% girls with normal weight think that they need to lose weight.47. On the whole, for 6 years white women had been occupying much more space in mainstream women’s magazines since 1999.48. Some negative effects such as depression and unhealthy eating habits in females are related to their being exposed to images of thin and young female bodies.49. The mass media has helped boost the cosmetic and the diet industries.50. It is reported that there is at least one message about the methods for women to change their bodily appearance on more than three-quarters of the covers of women’s magazines.51. Some film and television actresses even faint on the scene due to eating too little.52. Too much concern with appearance makes it impossible to change such abnormal trend.53. Researchers found that a real woman with Barbie-doll proportions would eventually die from malnutrition.54. The Quebec magazine Coup (e Pouce resists the trend by consistently including full-sized women in their fashion pages for several years.5 5. According to some analysts, the fundamental reason of imposing standards of beauty on women is economic profits.PartⅢ Reading ComprehensionSection B46.

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.长篇阅读Definitions of ObesityA) How does one define when a person is considered to be obese and not just somewhat overweight? Height-weight tables give an approximate guideline as to whether one is simply overweight or has passed into the obese stage.B) The World Health Organization recommends using a formula that takes into account a person's height and weight. The "Body Mass Index" (BMI) is calculated by dividing the person's weight in kilograms by the square of their height in meters, and is thus given in units of kg/m2. A BMI of 18.5-24.9 is considered to be the healthiest. A BMI of between 25 and 29.9 is considered to be overweight, while a BMI of over 30 is considered to be obese.C) However, it is recognized that this definition is limited as it does not take into account such variables as age, gender and ethnic origin, the latter being important as different ethnic groups have very different fat distributions. Anothershortcoming is that it is not applicable to certain very muscular people such as athletes and bodybuilders, who can also have artificially high BMIs. Agencies such as the National Cholesterol Education Program (NCEP) in the USA and the International Diabetes Foundation (IDF) are starting to define obesity in adults simply in terms of waist circumference.Health Effects of ObesityD) Over 2000 years ago, the Greek physician Hippocrates wrote that "persons who are naturally very fat are apt to die earlier than those who are slender". This observation remains very true today. Obesity has a major impact on a person's physical, social and emotional well-being. It increases the risk of developing diabetes mellitus type 2 ("mature onset diabetes") and also makes Type 2 diabetes more difficult to control. Thus weight loss improves the levels of blood glucose and blood fats, and reduces blood pressure. The association between obesity and coronary heart disease is also well-known.CancerE) Furthermore, in 2001 medical researchers established a link between being overweight and certain forms of cancer, and estimated that nearly 10,000 Britons per year develop cancer as a result of being overweight. This figure was made up of 5,893 women and 3,220 men, with the strongest associations being with breast and colon cancers. However, it is thought that being overweight may also increase the risk of cancer in the reproductive organs for women and in the prostate gland for men.F) The link between breast cancer and nutritional status is thought to be due to the steroid hormones oestrogen and progesterone, which are produced by the ovaries, and govern awoman's menstrual cycle. Researchers have found that the more a woman eats, or the more sedentary her lifestyle, the higher are the concentrations of progesterone. This link could explain why women from less affluent countries have lower rates of breast cancer. Women from less affluent nations tend to eat less food and to lead lifestyles which involve more daily movement. This lowers their progesterone level, resulting in lower predisposition to breast cancer.G) The Times newspaper, in 2002 reported that obesity was the main avoidable cause of cancer among non-smokers in the Western world!AgingH) Research published by St Thomas' Hospital, London, UK in 2005 showed a correlation between body fat and aging, to the extent that being obese added 8.8 years to a woman's biological age. The effect was exacerbated by smoking, and a non-overweight woman who smokes 20 cigarettes a day for 20 years added 7.4 years to their biological age. The combination of being obese and a smoker added at least ten years to a woman’s biological age, and although the study only involved women, the lead researcher Professor Tim Spector believes the finding would also apply to men.I) The aging effect was determined by measuring the length of telomeres, tiny "caps" on the ends of chromosomes, which help protect the DNA from the ageing process. Indeed, telomeres have been dubbed the "chromosomal clock" because, as an organism ages, they become progressively shorter, and can be used to determine the age of the organism. Beyond a certain point, the telomere becomes so short that it is no longer able to prevent the DNA of the chromosome from falling apart. It isbelieved that excess body fat, and the chemicals present in tobacco smoke release free radicals which trigger inflammation. Inflammation causes the production of white blood cells which increases the rate of erosion of telomeres.DementiaJ) Recent research (2005) conducted in the USA shows that obesity in middle age is linked to an increased risk of dementia, with obese people in their 40s being 74% more likely to develop dementia compared to those of normal weight. For those who are merely overweight, the lifetime risk of dementia risk was 35% higher.K) Scientists from the Aging Research Centre at the Karolinska Institute in Sweden have been able to take information such as age, number of years in education, gender, body mass index, blood pressure level, physical activity and genetic factors, assigning each a risk score. They then used this information to devise a predictive test for dementia. This test will enable people at risk, for the first time, to be able to affect lifestyle changes which will reduce their risk of contracting dementia.Other ProblemsL) The world-wide upsurge in obesity, particularly in children, is of major economic concern, liable to drain economies. Of further concern is that research conducted in Australia and published in 2006, shows that up to one third of breech pregnancies were undetected by the traditional "palpation" examination, the danger being greatest for those women who are overweight or obese—a growing proportion of mothers. This means that such women are not getting the treatment required to turn the baby around in time for the birth, and in many cases require an emergency Caesarean section.M) This is a true health-care crisis, far bigger than Severe Acute Respiratory Syndrome (SARS) and ultimately, even bigger than AIDS.对应题目：1. You can judge whether one is simply overweight or has passed into the obese stage according to the height-weight table.2. Using the "Body Mass Index" to define a person's weight ideal is limited, because it does not takes into account many variables such as age, gender and ethnic origin.3. A person's emotional well-being would be affected by obesity.4. Obesity has something to do with cancer in the prostate gland for man.5. Women from less affluent nations tend to have much less breast cancer.6. A non-overweight woman who smokes 20 cigarettes a day for 20 years added7.4 years to her biological age.7. The excess body fat, like the chemicals present in tobacco smoke, can lead to inflammation.8. Obese people in middle age run an increased risk of dementia .9. The predictive test for dementia will help people to affect lifestyle changes that will reduce their risk of contracting dementia.10. The world-wide upsurge in obesity, particularly in children, will possibly drain economies.参考答案：1. A2. C3. D4. E5. F6. H7. I8. J9. K10. L。

英语四级段落信息匹配题技巧及练习题

英语四级段落信息匹配题一、英语四级段落信息匹配题是什么？原快速阅读理解调整为长篇阅读理解，篇章长度和难度不变。

篇章后附有10个句子，每句一题。

每句所含的信息出自篇章的某一段落，要求考生找出与每句所含信息相匹配的段落。

有的段落可能对应两题，有的段落可能不对应任何一题。

四级考试需要各位同学做的是，大家需要去看十个左右的段落，然后去匹配十个信息点。

但是到六级当中，我们的难度就要增加了，我们见到的情况是六级当中变成了15个段落，去匹配十个信息点。

但总体来看，不管题型怎么变，其实学习方法没变，还是仍旧需要大家提高阅读的能力，比如说读文章的时候，是不是直接拿英语读，如果读快速阅读的时候，还是拿中文边翻译边读的话，会发现阅读速度一直会比较慢，所以那么长的文章很难找到细节，所以大家一定要养成拿英语直接阅读的这样一种习惯，这样才能保证我们的阅读真正速度又快又准。

二、样题：Section BDirections: 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 questions by marking the corresponding letter on Answer Sheet 2.Universities Branch OutA) As never before in their long history, universities have become instruments of national competition as well as instruments of peace. They are the place of the scientific discoveries that move economies forward, and the primary means of educating the talent required to obtain and maintain competitive advantage. But at the same time, the opening of national borders to the flow of goods, services, information and especially people has made universities a powerful force for global integration, mutual understanding and geopolitical stability.B) In response to the same forces that have driven the world economy, universities have become more self-consciously global: seeking students from around the world who represent the entire range of cultures and values, sending their own students abroad to prepare them for global careers, offering courses of study that address the challenges of an interconnected world and collaborative (合作的) research programs to advance science for the benefit of all humanity.C) Of the forces shaping higher education none is more sweeping than the movement across borders. Over the past three decades the number of students leaving home each year to study abroad has grown at an annual rate of 3.9 percent, from 800,000 in 1975 to 2.5 million in 2004. Most travel from one developed nation to another, but the flow from developing to developed countries is growing rapidly. The reverse flow, from developed to developing countries, is on the rise, too. Today foreign students earn 30 percent of the doctoral degrees awarded in the United States and 38 percent of those in the United Kingdom. And the number crossing borders for undergraduate study is growing as well, to 8 percent of the undergraduates at Am erica’s best institutions and 10 percent of all undergraduates in the U.K. In the United States, 20 percent of the newly hired professors in science and engineering are foreign-born, and in Chinamany newly hired faculty members at the top research universities received their graduate education abroad.D) Universities are also encouraging students to spend some of their undergraduate years in another country. In Europe, more than 140,000 students participate in the Erasmus program each year, taking courses for credit in one of 2,200 participating institutions across the continent. And in the United States, institutions are helping place students in summer internships (实习) abroad to prepare them for global careers. Yale and Harvard have led the way, offering every undergraduate at least one international study or internship opportunity—and providing the financial resources to make it possible.E) Globalization is also reshaping the way research is done. One new trend involves sourcing portions of a research program to another country. Yale professor and Howard Hughes Medical Institute investigator Tian Xu directs a research center focused on the genetics of human disease at Shanghai’s Fudan University, in collaboration with faculty colleagues from both schools. The Shanghai center has 95 employees and graduate students working in a 4,300-square-meter laboratory facility. Yale faculty postdoctors and graduate students visit regularly and attend videoconference seminars with scientists from both campuses. The arrangement benefits both countries; Xu’s Yale lab is more productive, thanks to the lower costs of conducting research in China, and Chinese graduate students, postdoctors and faculty get on-the-job training from a world-class scientist and his U.S. team.F) As a result of its strength in science, the United States has consistently led the world in the commercialization of major new technologies, from the mainframe computer and the integrated circuit of the 1960s to the Internet infrastructure (基础设施) and applications software of the 1990s. The link between university-based science and industrial application is often indirect but sometimes highly visible: Silicon Valley was intentionally created by Stanford University, and Route 128 outside Boston has long housed companies spun off from MIT and Harvard. Around the world, governments have encouraged copying of this model, perhaps most successfully in Cambridge, England, where Microsoft and scores of other leading software and biotechnology companies have set up shop around the university.G) For all its success, the United States remains deeply hesitant about sustaining the research-university model. Most politicians recognize the link between investment in science and national economic strength, but support for research funding has been unsteady. The budget of the National Institutes of Health doubled between 1998 and 2003, but has risen more slowly than inflation since then. Support for the physical sciences and engineering barely kept pace with inflation during that same period. The attempt to make up lost ground is welcome, but the nation would be better served by steady, predictable increases in science funding at the rate of long-term GDP growth, which is on the order of inflation plus 3 percent per year.H) American politicians have great difficulty recognizing that admitting more foreign students can greatly promote the national interest by increasing international understanding. Adjusted for inflation, public funding for international exchanges and foreign-language study is well below the levels of 40 years ago. In the wake ofSeptember 11, changes in the visa process caused a dramatic decline in the number of foreign students seeking admission to U.S. universities, and a corresponding surge in enrollments in Australia, Singapore and the U.K. Objections from American university and business leaders led to improvements in the process and a reversal of the decline, but the United States is still seen by many as unwelcoming to international students.I) Most Americans recognize that universities contribute to the nation’s well-being through their scientific research, but many fear that foreign students threaten American competitiveness by taking their knowledge and skills back home. They fail to grasp that welcoming foreign students to the United States has two important positive effects: first, the very best of them stay in the States and—like immigrants throughout history—strengthen the nation; and second, foreign students who study in the United States become ambassadors for many of its most cherished (珍视) values when they return home. Or at least they understand them better. In America as elsewhere, few instruments of foreign policy are as effective in promoting peace and stability as welcoming international university students.注意：此部分试题请在答题卡 2 上作答。

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.How to Make Attractive and Effective PowerPoint PresentationsA) Microsoft PowerPoint has dramatically changed the way in which academic and business presentations are made. This article outlines few tips on making more effective and attractive PowerPoint presentations.The TextB) Keep the wording clear and simple. Use active, visual language. Cut unnecessary words—a good rule of thumb is to cut paragraphs down to sentences, sentences into phrases, and phrases into key words. Limit the number of words and lines per slide. Try the Rule of Five-five words per line, five lines per slide. If too much text appears on one slide, use the AutoFit feature to split it between two slides. Click within the placeholder to display the AutoFit Options button (its symbol is two horizontal lines with arrows above and below), then click on the button and choose Split Text between Two Slides from the submenu.C) Font size for titles should be at least 36 to 40, while the text body should not be smaller than 24. Use only two font styles per slide—one for the title and the other for the text. Choose two fonts that visually contrast with each other. Garamond Medium Condensed and Impact are good for titles, while Garamond or Tempus Sans can be used for the text body.D) Embed the fonts in your presentation, if you are not sure whether the fonts used in the presentation are present in the computer that will be used for the presentation. To embed the fonts: (1) On the File menu, click Save As. (2) On the toolbar, click Tools, click Save Options, select the Embed TrueType Fonts check box, and then select Embed characters in use only.E) Use colors sparingly; two to three at most. You may use one color for all the titles and another for the text body. Be consistent from slide to slide. Choose a font color that contrasts well with the background.F) Capitalizing the first letter of each word is good for the title of slides and suggests a more formal situation than having just the first letter of the first word capitalized. In bullet point lines, capitalize the first word and no other words unless they normally appear capped. Upper and lower case lettering is more readable than all capital letters. Moreover, current styles indicate that using all capital letters means you are shouting. If you have text that is in the wrong case, select the text, and then click Shift+F3 until it changes to the case style that you like. Clicking Shift+F3 toggles the text case between ALL CAPS, lower case, and Initial Capital styles.G) Use bold or italic typeface for emphasis. Avoid underlining, it clutters up the presentation.Don’t center bulleted lists or text. It is confusing to read. Left align unless you have a good reason not to. Run “spell check”on your show when finished.The BackgroundH) Keep the background consistent. Simple, light textured backgrounds work well. Complicated textures make the content hard to read. If you are planning to use many clips in your slides, select a white background. If the venue of your presentation is not adequately light-proof, select a dark-colored background and use any light color for text. Minimize the use of “bells and whistles”such as sound effects, “flying words” and multiple transitions. D on’t use red in any fonts or backgrounds. It is an emotionally overwhelming color that is difficult to see and read.The ClipsI) Animations are best used subtly; too much flash and motion can distract and annoy viewers. Do not rely too heavily on those images that were originally loaded on your computer with the rest of Office. You can easily find appropriate clips on any topic through Google Images. While searching for images, do not use long search phrases as is usually done while searching the web-use specific words.J) When importing pictures, make sure that they are smaller than two megabytes and are in a .jpg format. Larger files can slow down your show. Keep graphs, charts and diagrams simple, if possible. Use bar graphs and pie charts instead of tables of data. The audience can then immediately pick up the relationships.The PresentationK) If you want your presentation to directly open in the slide show view, save it as a slide show file using the following steps. Open the presentation you want to save as a slide show. On the File menu, click Save As. In the Save as type list, click PowerPoint Show. Your slide show file will be saved with a ppt file extension. When you double-click on this file, it will automatically start your presentation in slide show view. When you’re done,PowerPoint automatically closes and you return to the desktop. If you want to edit the slide show file, you can always open it from PowerPoint by clicking Open on the File menu.L) Look at the audience, not at the slides, whenever possible. If using a laser pointer, don’t move it too fast. For example, if circling a number on the slide, do it slowly. Never point the laser at the audience. Black out the screen (use “B”on the keyboard) after the point has been made, to put the focus on you. Press the key again to continue your presentation.M) You can use the shortcut command [Ctrl]P to access the Pen tool during a slide show. Click with your mouse and drag to use the Pen tool to draw during your slide show. To erase everything you’ve drawn, press the E key. To turn off the Pen tool, press [Esc] once.MiscellaneousN) Master Slide Set-Up: The “master slide”will allow you to make changes that are reflected on every slide in your presentation. You can change fonts, colors, backgrounds, headers, and footers at the “master slide”level. First, go to the “View” menu. Pull down the “Master”menu. Select the “slide master”menu. You may now make changes at this level that meet your presentation needs.对应题目：1. The ways in which academic and business presentations are made have been changed by Microsoft PowerPoint.2.

Pressing the E key can help you to erase everything you've drawn.10. In ord er to meet your presentation needs, you can make changes at the “slide master”level.答案参考：1.

Every time I go to the library——and I go more than once a week——I invariably make a beeline to the card catalog before anything else.It’s the nucleus of any public library.The card catalog lists every book in the library by：1.author;2.title;3.subject.Let’s pick an interesting subject to look up.I have always been fascinated by astronomy.You’ll be surprised at the wealth of material you will find under “a strong my” to draw upon.And the absorbing books you didn’t know existed on it.CAUTION：Always have a pencil and paper when you use the card catal09.G) Once you jot down the numbers of the books you are interested in，you are ready to find them on the shelves.Libraries call the shelves “the stacks”.In many smaller libraries，whichyou’ll be using，the stacks will be open for you to browse.To me there is a special thrill in tracking down the books I want in the stacks !For invariably,I find books about which I knew nothin9，and these often turn out to be the very ones l need.You will find the same thing happening to you when you start to browse in the stacks.“A learned mind is the end product of browsing.”CAUTION：If you take a book from the stack s to your work desk，do not try to return it to its proper place.That’s work for the experts.If you replace it incorrectly, the next seeker won’t be able to find it.H)Some of the brightest and rmed men and women in America are the librarians who specialize in providing reference help.Introduce yourself State your problem.And be amazed at how much he p you will receive.CAUTION：Don’t waste the time of this expert by asking silly questions you ought to solve yourself.Save the reference librarian for the really big ones.I) You shot：ld also learn to use the Reader's Guide to Periodical Literature.This green—bound index is me of the most useful items in any library.It indexes all the articles in the major magazines，including newspaper magazine supplements.Thus it provides a guide to the very latest expert information of any subject that interests you.So if you want to do a really first—class job，find out which magazines your library subscribes to，then consult the Reader's Guide and track down recent articles on your subject.When you use this wonderful tool effectively, you show the mark of a real scholar.J) Since you can take most books home，but not magazines，take full notes when using the latter. Many libraries today provide a reprographic machine that can quickly copy pages you needfrom magazines and books.Ask about it：If you are working on a project of some size which will require repeated library visits，keep a small notebook in which you record the identification numbers of the books you will be using frequently.This will save you valuable time，because you won’t have to consult the card catalog or search aimlessly through the stacks each time you visit for material you seek.Sol fie of the very best books in any library are the reference books，which may not be taken home.Learn what topics they cover and how best to use them，for these books are wonderful repositories (储藏室、资料库)of human knowledge.K) Your library can give you help on any subject.It can even be your business and legal advisor.How many times have you scratched your head over how to get a tax rebate(折扣)on your summer job?

英语四级段落信息匹配题练习题：Jaguars Dont 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 worlds 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. Whats 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 11017, 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 (慎重的 ) 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 11017 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 dont 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 101 years, there have been few, if any, resident breedingpopulations 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 Services 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 timesurviving 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 dont 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 havent 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 expenseto 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 our country, 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 animalswill 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 countrys 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 oftheir 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 dont 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 didnt 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.1.I)。

Now websites such as Airbnb.RelayRides and SnapGoods match upowners and renters；smartphones with GPS let people see where the nearest rentablecar is parked；social networks provide a way to check up on people and build trust；and online payment systems handle the billing.Whats mine is yours.for a feeC）Just as peer-to-peer businesses like eBay allow anyone to become a retailer.sharing sites let individuals act as an ad hoc（临时的）taxi service.car-hire firm or boutiquehotel（精品酒店）as and when it suits them.Just go online or download an app.Themodel works for items that are expensive to buy and are widely owned by peoplewho do not make full use of them. Bedrooms and cars are the most obviousexamples.but you can also rent camping spaces in Sweden.fields in Australia andwashing machines in France. As advocates of the sharing economy like to putit.access trumps（胜过）ownership.D）Rachel Botsman.the author of a book on the subject.says the consumer peer-to-peer rental market alone is worth $ 26 billion.Broader definitions of the sharing economyinclude peer-to- peer lending or putting a solar panel on your roof and selling powerback to the grid（电网）. And it is not just individuals；the web makes it easier forcompanies to rent out spare offices and idle machines.too.But the core of the sharingeconomy is people renting things from each other.E）Such “collaborative（合作的）consumption”is a good thing for several reasons.Owners make money from underused assets.Airbnb says hosts in SanFrancisco who rent out their homes do so for an average of 58 nights a year.making$ 9.300.Car owners who rent their vehicles to others using RelayRides make anaverage of $ 250 a month；some make more than $ 1.000. Renters.meanwhile.payless than they would if they bought the item themselves.or turned to a traditionalprovider such as a hotel or car-hire firm.And there are environmental benefits. too：renting a car when you need it.rather than owning one.means fewer cars are requiredand fewer resources must be devoted to making them.F）For sociable souls. meeting new people by staying in their homes is part of the charm.Curmudgeons（倔脾气的人）who imagine that every renter is a murderer can stillstay at conventional hotels.For others. the web fosters trust.As well as thebackground checks carried out by platform owners.online reviews and ratings areusually posted by both parties to each transaction.which makes it easy to spot baddrivers.bathrobe-thieves and surfboard-wreckers. By using Facebook and othersocial networks. participants can check each other out and identify friends（or friends of friends）in common.An Airbnb user had her apartment trashed in 2011.Butthe remarkable thing is how well the system usually works.Peering into the futureG）The sharing economy is a little like online shopping. which started in America 15 years ago.At first.people were worried about security.But having made a successfulpurchase from.say.Amazon.they felt safe buying ing Airbnbor a car-hire service for the first time encourages people to try otherofferings.Next.consider eBay.Having started out as a peer-to-peer marketplace. it isnow dominated by professional “power sellers”（many of whom started out asordinary eBay users）.The same may happen with the sharing economy.which alsoprovides new opportunities for enterprise. Some people have bought cars solely torent them out.for example.H）Existing rental businesses are getting involved too. Avis.a car-hire firm.has a share ina sharing rival. So do GM and Daimler. two carmakers. In future. companies maydevelop hybrid（混合的）models. listing excess capacity（whether vehicles.equipment or office space）on peer-to-peer rental sites.In the past.new ways of doingthings online have not displaced the old ways entirely.But they have often changedthem.Just as internet shopping forced Wal-mart and Tesco to adapt. so online sharingwill shake up transport. tourism. equipment-hire and more.I）The main worry is regulatory uncertainty. Will room-renters be subject to hotel taxes.for example? In Amsterdam officials are using Airbnb listings to track downunlicensed hotels.In some American cities.peer-to-peer taxi services have beenbanned after lobbying by traditional taxi firms.The danger is that although somerules need to be updated to protect consumers from harm.existing rental businesseswill try to destroy competition. People who rent out rooms should pay tax.ofcourse.but they should not be regulated like a Ritz-Carlton hotel. The lighter rulesthat typically govern bed-and-breakfasts are more than adequate.J）The sharing economy is the latest example of the internets value to consumers.Thisemerging model is now big and disruptive（颠覆性的）enough for regulators andcompanies to have woken up to it.That is a sign of its immense potential.It is time tostart caring about sharing.46.Sharing items such as cars does good to the environment.47.Airbnbs success clearly illustrates the emergence of a huge sharing economy.48.The major concern about the sharing economy is how the government regulates it.49.The most frequently shared items are those expensive to buy but not fully used.50.The sharing economy has a promising future.51. Online sharing will change the way business is done in transportation. travel. rentals.etc.52.Airbnb is a website that enables owners and renters to complete transactions online.53.The sharing economy is likely to go the way of online shopping.54.One advantage of sharing is that owners earn money from renting out items not made full use of.55.Sharing appeals to the sociable in that they can meet new people.精讲精练2012-06Passage OneQuestions 57 to 61 are based on the following passage.In times of economic crisis. Americans turn to their families for support. If the Great Depression is any guide.we may see a drop in our skyhigh divorce rate.But this won't necessarily represent an increase in happy marriages. In the long run.the Depression weakened American families.and the current crisis will probably do the same.We tend to think of the Depression as a time when families pulled together to survive huge job losses.By 1932.when nearly one-quarter of the workforce was unemployed.the divorce rate had declined by around 25% from 1929.But this doesn't mean people were suddenly happier with their marriages.Rather.with incomes decreasing and insecure jobs.unhappy couples often couldn ' t afford to divorce.They feared neither spouse could manage alone.Today.given the job losses of the past year.fewer unhappy couples will risk starting separate households.Furthermore.the housing market meltdown will make it more difficult for them to finance their separations by selling their homes.After financial disasters family members also tend to do whatever they can to help each other and their communities.A 1940 book. The Unemployed Man and His Family. described a family in which the husband initially reacted to losing his job “with tireless search for work.”He was always active.looking for odd jobs to do.The problem is that such an impulse is hard to sustain Across the country.many similar families were unable to maintain the initial boost in morale（士气）.For some.the hardships of life without steady work eventually overwhelmed their attempts to keep their families together. The divorce rate rose again during the rest of the decade as the recovery took hold.Millions of American families may now be in the initial stage of their responses to the current crisis.working together and supporting one another through the early months of unemployment.Today's economic crisis could well generate a similar number of couples whose relationships have been irreparably（无法弥补地）ruined.So it's only when the economy is healthy again that we'll begin to see just how many broken families have been created.注意：此部分试题请在答题卡 2 上作答。

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.

2020年四级阅读段落信息匹配训练（8）2020年四级阅读段落信息匹配训练(8) The Art of FriendshipA) One evening a few years ago I found myself in an anxiety. Nothing was really wrong my family and I were healthy, my career was busy and successful -- I was just feeling vaguely down and in need of a friend who could raise my spirits, someone who would meet me for coffee and let merant until the clouds lifted.I dialed my best friend, who now lives across the country in California, and got her voicemail. That's when it started to dawn on me -- lonesomeness was at the root of my dreariness. My social life had dwindled to almost nothing, but somehow until that moment I'd been too busy to notice. Now it hit me hard. My old friends, buddies since college or even childhood, know everything about me; when they left, they had taken my context with them.B) Research has shown the long-range negative consequences of social isolation on one's health. But my concerns were more short-term. I needed to feel understood right then in the way that only a girlfriend can understand you. I knew it would be wrong to expect my husband to replace my friends： He couldn't, and even if he could, to whom would I then complain about my husband? So I resolved to acquire new friends -- women like me who had kids and enjoyed rolling their eyes at the worlda little bit just as I did. Since I'd be making friends with more intention than I'd ever given the process, I realized I could be selective, that I could in effect design my own social life. The down side, of course, was that I felt pretty frightened.C) After all, it's a whole lot harder to make friends in midlifethat it is when yon're younger -- a fact woman I've spoken with point out again and again. As Leslie Danzig, 41,a Chicago theater director and mother, sees it, when you'rein your teens and 20s, you're more or less friends with everyone unless there's a reason not to be. Your college roommate becomes your best pal at least partly due to proximity. Now there needs to be a reason to be friends. "There are many people I'm comfort-able around, but Iwouldn't go so far as to call them friends. Comfort isn't enough to sustain a real friendship," Danzig says.D) At first, finding new companions felt awkward. At 40 I couldn't run up to people the way my4-year-old daughters do in the playground and ask, "Will you be my friend? Every time you start anew relationship, you're vulnerable again," agrees Kathleen Hall, D Min, founder and CEO of the Stress Institute, in Atlanta. "You're asking, 'Would you like to come into my life?' It makes us self-conscious."E) Fortunately, my discomfort soon passed. I realizedthat as a mature friend seeker my vulnerability risk was actually pretty low. If someone didn't take me up on my offer, so what： I wasn't in junior high, when I might have been rejected for having the wrong clothes or hair. At my age I have amassed enough self-esteem to realize that I have plenty to offer.F) We're all so busy, in fact, that mutual interests -- say, in a project, class, or cause that we already make time for -- become the perfect catalysts for bringing us incontact with candidates for camaraderie. Michelle Mertes, 35,a teacher and mother of two in Wausau, Wisconsin, says anew friend she made at church came as a pleasant surprise. "In high school I chose friends based on their popular-ity and howbeing part of their circle might reflect on me. Now'sit's our shared values and activities that count." Mertes says her pal, with whom she organized the church's youth programs, is nothing like her but their drive and organizational skills make them ideal friends.G) Happily, as awkward as making new friends can be,self-esteem issues do not factor in -- or if they do, you can easily put them into perspective. Danzig tells of the mother of a child in her son's pre-school, a tall, beautiful woman who is married to a big-deal rock musician. "I said to my husband, she's too cool for me,'" she jokes. "I get intimidated by people. But once I got to know her, she turned out to be pretty laid-back and friendly." In the end there was no chemistry between them, so they didn't become good pals. "I realized that we weren't each other's type, but it wasn't about hierarchy." What midlife friendship is about, it seems, is reflecting the person you've become (or are still becoming) back at yourself, thus reinforcing the progressyou've made in your life.H) Harlene Katzman, 41, a lawyer in New York City, notes that her oldest friends knew her back when she was less sure of herself. As much as she loves them, she believes they sometimes respond to is-sues in light of who she once was. An old chum has the goods on you. With recently made friends, you can turn over a new leaf.。
