1、African wild dogFinding a babysitter while you go out to work is, for example, an inconvenience. For the African wild dog, one of the continent\'s most endangered carnivores （食肉动物), it\'s a matter of life and death. A new research shows that once packs (兽群) fall below a certain size, they are not enough animals to both hunt food and stay at home protecting the young.The African wild dog has declined drastically over the past century. Habitual loss (栖息地的丧失), persecution and unexplained outbreaks of disease have all been blamed. Only 3, 000 to5,000 animals remain, and the species is expected to go extinct within decades if the trend continues.Other large carnivores such as the spotted hyena (鬣狗) face similar pressures, yet are not declining. Now Franck Courchamp of Cambridge University has found a reason why. The dog\'s weakness lies in its social organization.Within each pack of up to 20 adults and pups, only the dominant male and female breed. The remaining animals help raise the pups, cooperating to hunt prey and defend the kill from other carnivores.Because pups can\'t keep up on a hunt, large packs leave an adult behind to protect them from predators (捕猎者), which include lions and hyenas. But leaving a babysitter also carries costs. A smaller hunting party is less able to tackle large prey and to defend the kill. There is also one less stomach in which to carry food back to the den, and one more mouth to feed when they get there.Courchamp investigated this awkward trade-off (权衡) by modeling how the costs of a babysitter change with decreasing pack size. This showed that packs of more than five adults should be able to feed all the pups and still spare a babysitter. But with smaller packs, either the hunting or the babysitting suffers, or the animals have to compensate by increasing the number of hunting excursions which itself carries a cost to the pack.Field observations in Zimbabwe supported the model. Packs of five animals or fewer left pups unguarded more frequently than larger packs did. There was also evidence that when they did leave a babysitter, they were forced to hunt more often.A pack which drops below a critical size becomes caught in a vicious circle (恶性循环), says Courchamp, who is now at Paris-Sud University. "Poor reproduction and low survival further reduces pack size, culminating in (最终造成) failure of the whole pack. " And deaths caused by human activity, says Courchamp, may be what reduce pack numbers to below the sustamable threshold. Mammal ecologist Chris Carbone at London\'s Institute of Zoology agrees. Maintaining the integrity of wild dog packs will be vitalin preserving the species, he says.The remaining lions will die out within decades.【单选题】

2、DyslexiaAs many as 20% of all children in the United States suffer from some form of the learning disorder called dyslexia.Experts on dyslexia say that the problem is not disease. They say that persons with dyslexia use information in a different way. One of the world\'s great thinkers and scientists, Albert Einstein was dyslexic. Einstein said that he never thought in words the way that most people do. He said that he thought in pictures instead. The American inventor Thomas Edison was also dyslexic. Dyslexia first was recognized in Europe and the United States more than 80 year ago. Many years passed before doctors discovered that persons with the disorder were not mentally slow or disabled. The doctors found that the brains of persons with dyslexia are different. In most people, the left side of the brain, the part that controls language is larger than the right side. In persons with dyslexia, the right’ side of the brain is bigger. Doctors are not sure what causes this difference. However, research has shown that dyslexia is more common in males that in females, and it is found more often in persons who are left-handed. No one knows the cause of dyslexia, but some scientists believe that it may result from chemical changes in a baby\'s body long before it is born. They are trying to find ways to teach persons with dyslexia. Dyslexic persons think differently and need special kinds of teaching help. After they have solved their problems with language, they often show themselves to be especially intelligent or creative.Many great thinkers and scientists in the world are dyslexic.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:C

答案解析:题目中的关键词为great thinkers and scientists，我们在第2段中找到答案所在句。但是通过对比发现，原文中的限制词是one of，而题目中却是many。再仔细阅读原文发现，文中仅提到爱因斯坦和爱迪生为读写困难症的患者，并未讲述除爱因斯坦和爱迪生以外的思想家和科学家的情况，因此该题的答案为C。

3、Ceasing to Wear TiesIt\'s useless. It\'s dirty. It spreads disease. That\'s why the British Medical Association in the UK recently called for hospital doctors to stop wearing ties.That leads to another question. Why does anyone wear a tie? Ties serve no purpose. They do not cover any part of your body and keep you warm. They always seem to get covered in food stains. Perhaps that is the purpose of the tie. It lets everyone know what you just ate.Ties have an odd history. Soldiers from Croatia, in Eastern Europe, served as mercenaries (雇佣军) in various conflicts in the 17th century. They were identified by brightly colored pieces of silk worn around the neck. Known as cravats(围巾), these became a popular fashion item in France and eventually evolved into the tie.It\'s an interesting story, but it doesn\'t tell us why men want to put useless pieces of cloth or silk around their necks. The answer seems to be about identification(身份证明 ). In the 19th-century Britain, ties were used by universities, military regiments (团), sports clubs, schools and gentleman\'s clubs. Each tie was in a particular set of colors which identified the wearer as a member of that organization. Wearing ties was also the mark of Britain\'s most powerful classes. That made the tie itself a symbol of power and respect. And that led it to be adopted by a much larger class-the business class.You cannot wear a tie if you work with machinery, so wearing a tie became a sign that you were a man who used his brain to make a living, rather than his hands. It showed you were serious. It showed you were a professional. It meant that everyone who wanted a job in business had to wear one. It was just impossible to take seriously a man who did not wear a piece of colored silk around his neck. This is how millions of people came to wear ties across the world.Is there a future for ties? The signs are not promising. Many political leaders, including British Prime Minister Tony Blair, now go without ties.Paragraph 6 ________.【单选题】

A.Origin of the tie

B.British ties

C.Uselessness of the tie

D.Old-fashioned ties

E.Role of the tie

F.Signs of a tieless era

正确答案:F

答案解析:第六段的主题句是第二句：The signs are not promising.这里the signs后边省略了of the future of ties。该句说明领带的前景不是很好。比如在后一句中讲到英国首相布莱尔等政治家经常在公共场合不再戴领带，这进一步说明了以后人们可能不再打领带。F选项Signs of a tieless era与其表达相符，故F为正确答案。

5、Travel Across AfricaFor six hours we shot through the barren (荒芜的) landscape of the Karoo desert in South Africa. Just rocks and sand and baking sun. Knowing our journey was ending, Daniel and I just wanted to remember all we had seen and done. He used a camera. I used words. I had already finished three notebooks and was into the fourth, a beautiful leather notebook I\'d bought in a market in Mozambique.Southern Africa was full of stories and visions. We were almost drunk on sensations. The roaring (咆哮) of the water at Victoria Falls, the impossible silence of the Okavango Delta in Botswana.And then the other things, dogs in the streets, whole families in Soweto livng in one room, a kilometre from clean water.As we drove towards the setting sun, a quietness fell over us. The road was empty and we hadn\'t seen another car for hours. And as I drove, something caught my eye. Something moved close enough to touch them, to smell their hot breath. I didn\'t know how long they had been there next to us.I shouted to Dan: "Look!" But he was in a deep sleep, his camera lying useless by his feet. They raced the car for a few seconds, then disappeared far behind us, a memory of heroic forms in the red landscape. When Daniel woke up an hour later I told him what had happened."Wild horses?" he said. "Why didn\'t you wake me up, Sophia?""I tried, but they were gone after a few seconds.""Are you sure you didn\'t dream it?""You were the one who was sleeping!""Typical," he said, "The best photos are the ones we never take."We checked into a dusty hotel and slept the sleep of the dead.Sophia woke Daniel up so that he could take photos of the horses.【单选题】

7、Why People Use Pseudonyms (假名字)?You can\'t choose the name you are given at birth, but in many countries you can change it legally when you reach adulthood. Of course, most people never change their names even if they feel unhappy about them. However some people do take this course of action－particularly artists! What makes an artist want to change their name? Sometimes it\'s for purely personal reasons, such as the Nobel Prize winning poet from Chile, Neftalf Reyes. He didn\'t want his father to know he was writing poetry, so he changed his name to Pablo Neruda when he was a young man. At other times the reason may appear strange, take the case of the Portuguese poet Femando Pessoa, who wrote under 75 different names. The reason? "When I use a different name, I always write in a different way," he explained. In most cases, however , people change their names for social, historical, political, or cultural reasons. Here are some of the most ____: reason. The person\'s real name is just too long and difficult to remember. Let\'s be honest, Madonna Louise Ciccone is not as easy to remember as just plain Madonna. And short names are much easier to remember: William Bradley became Brad Pitt and Edson Arantes do Nascimento became Pele.Sometimes names are changed for marketing purposes. For example, if a name sounds too foreign, it may be changed to something that is more recognizable in a market. So in the film world, Ramon Estsvez adopted the name Martin Sheen. Or maybe the artist\'s real name doesn\'t sound attractive－Chad Everett does sound a lot better than Raymond Cramton.Artists sometimes choose the name of someone they admire. Robert Zimmerman changed his name to Boo Dylan because of his admiration for the Welsh poet, Dylan Thomas.Another reason may be practical: in the past, women found it very difficult to get published. To avoid this situation, they sometimes gave themselves men\'s names, so the English author Mary Ann Evans became George Eliot, and she did get her books published!【单选题】

A.scientific

B.common

C.technical

D.average

正确答案:B

答案解析:本题存一定难度，但干扰项干扰不大，依据上下文逻辑，文章此处是说“下面是一些最普通的（理由）”正确答案是B。

8、The State of Marriage TodayIs there something seriously wrong with marriage today? During the past 50 years, the rate of divorce in the United States has exploded: almost 50% of marriages end in divorce now, and the evidence suggests it is going to get worse. If this trend continues, it will lead to the breakup of the family, according to a spokesperson for the National Family Association. Some futurists predict that in 100 years, the average American will marry at least four times, and extramarital (婚外的) affairs will be even more common than now.But what are the reasons for this, and is the picture really so gloomy (明暗的)? The answer to the first question is really quite simple: marriage is no longer the necessity it once was. The institution of marriage has been based for years partly on economic need. Women used to be economically dependent on their husbands－as they usually didn\'t have jobs outside the home. But with the rising number of women in well－paying jobs, this is no longer the case, So they don\'t feel that they need to stay in a failing marriage.In answer to the second question, the outlook may not be as pessimistic (悲观的) as it seems. While the rate of divorce has risen, the rate of couples marrying has never actually fallen very much, so marriage is still quite popular. In addition to this, many couples now simply live together and don\'t bother to marry. These couples are effectively married, but they do not appear in either the marriage or divorce statistics. In fact, more than 50% of first marriages survive.So is marriage really an outdated institution? The fact that most people still get married indicates that it isn\'t. And it is also true that married couples have a healthier life than single people: they suffer less from stress and its consequences, such as heart problems, and married men generally consider themselves more contented than their single counterparts. Perhaps the key is to find out what makes a successful marriage and apply it to all of our relationships!Which of the following about marriage is NOT mentioned in the passage? ____【单选题】

A.It is important to discover what makes a marriage successful.

B.Marriage has long been partly an economic need.

C.It is a fact that most people choose to get married.

D.Many people went abroad after divorce.

正确答案:D

答案解析:本题难度也不大，但是需要考生认真通读全文，读完后可以发现，文章并没有提到人们离婚后出国，所以答案是D。

9、Ford(1)Ford\'s great strength was the manufacturing process not invention. Long before he started a car company, he was a worker, known for picking up pieces of metal and wire and turning them into machines. He started putting cars together in 1891, although it was by no means the first popular automobile, the Model T showed the world just how creative Ford was at combining technology and market.(2)The company\'s assembly line alone. threw America\'s Industrial Revolution into overdrive(高速运转）. Instead of having workers put together the entire car, Ford\'s friends, who were great toolmakers from Scotland, organized teams that added parts to each Model T as it moved down a line. By the time Ford\' s Highland Park plant was humming (嗡嗡作响) along in 1914, the world\'s first automatic conveyor belt could turn out a car every 93 minutes.（3）The same year Henry Ford shocked the world with the $5 a day minimum Wage scheme, the greatest contribution he had ever made. The average Wage in the auto industry then was $2. 34 for a9-hour shift. Ford not only doubled that he also took an hour off the workday. In those years it was unthinkable that a man could be paid that much for doing something that didn\'t involve an awful lot of training or education. The Wall Street Journal called the plan "an economic crime" and critics everywhere laughed at Ford.(4)But as the wage increased later to daily $10, it proved a critical component of Ford\'s dream to make the automobile accessible to all The critics were too stupid to understand that because Ford had lowered his costs per car, the higher wages didn\'t matter, except for making it possible for more people to buy cars.Ford was the first to adopt ____【单选题】

A.criticized by the media

B.the low wage in the auto industry

C.own a car

D.Produce cars in large numbers

E.the 8-hour-shift practice

F.combined technology and market

正确答案:E

答案解析:第3段讲到，当时汽车工业实行的是9小时工作制，平均每小时2. 34美元。Ford不仅把工资翻了番，而且还把工作日中的工作时数去除了一小时。也就是说，Ford是第一个实行8小时工作的人。

10、Electric BackpackBackpacks are convenient. They can hold your books, your lunch, and a change of clothes, leaving your hands free to do other things. Someday, if you don\'t mind carrying a heavy load, your backpacks might also power your MP3 player, keep your cell phone running, and maybe even light your way home.Lawrence C. Rome and his colleagues from the University of Pennsylvania in Philadelphia and the Marine Biological Laboratory in Woods Hole, Mass, have invented a backpack that makes electricity from energy produced while its wearer walks. In military actions, search-and-rescue operations, and scientific field studies, people rely increasingly on cell phones, global positioning system (GPS) receivers, night-vision goggles, and other battery-powered devices to get around and do their work. The backpack\'s electricity-generating feature could dramatically reduce the amount of a wearer\'s load now devoted to spare batteries, report Rome and his colleagues in the Sept. 9, Science.The backpack\'s electricity-creating powers depend on springs used to hang a cloth pack from its metal frame. The frame sits against the wearer\'s back, and the whole pack moves up and down as the person walks. A gear mechanism converts vertical movements of the pack to rotary motions of an electrical generator, producing up to 7. 4 watts.Unexpectedly, tests showed that wearers of the new backpack alter their gaits in response to the pack\'s oscillations, so that they carry loads more comfortably and with less effort than they do ordinary backpacks. Because of that surprising advantage, Rome plans to commercialize both electric and non-electric versions of the backpack.The backpack could be especially useful for soldiers, scientists, mountaineers, and emergency workers who typically carry heavy backpacks. For the rest of us, power-generating backpacks could make it possible to walk, play video games, watch TV, and listen to music, all at the same time. Electricity-generating packs aren\'t on the market yet, but if you do get one eventually, just make sure to look both ways before crossing the street!What is the most important feature of the backpack invented by Lawrence C. Rome and his colleagues?【单选题】

A.It produces electricity for electronic devices while the wearer walks.

B.It can be used as cell phones, GPS in the military actions or field studies.

C.It is small and convenient.

D.It is light and easy to carry.

正确答案:A

答案解析:第2段的第1句说，Lawrence C. Rome及其同事们发明的这种背包，当背着背包走路时，会有电能产生。该段最后一句告诉我们，背包的这种性能可减少背包的重量，因为不必携带备用电池。
