1、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 ａｌｔｅｒtheir 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 fｏｒsoldiers, scientists, mountaineers, ａｎｄ　emergency workers who typically carry heavy backpacks. Fｏｒthe 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!The word "springs" in Paragraph 3 means .【单选题】

A.a small stream of water flowing naturally from the earth

B.the season of the year, occurring between winter ａｎｄ　summer

C.the act ｏｒan instance of jumping ｏｒleaping

D.a length of metal wound around, which returns to its original shape after being pushed

正确答案:D

答案解析:springs在此是弹簧的意思。spring是一个多义词：泉水、春天、弹跳。

2、Shopping at Second - hａｎｄ　Clothing StoresWhen 33 years old Pete Barth was in college, shopping at second - hａｎｄ　clothing stores was just something he did－"like changing the tires on his car." He looked at his budget ａｎｄ　decided he could save a lot of money by shopping fｏｒclothes at thrift shops."Even new clothes are fairly disposable (用后即丢掉的) ａｎｄ　wear out after a couple of years," Barth said. "In thrift shops, you can find some great stuff whose quality is better than new clothes."Since then, Barth, who works at a Goodwill thrift shop in the US state of Florida, has found that there are all kinds of reasons fｏｒshopping fｏｒsecond - hａｎｄ　clothing. Some people, like him, shop to save money. Some shop fｏｒa crazy - looking shirt. ａｎｄ　some shop as a means of conserving energy ａｎｄ　helping the environment.Pat Akins, an accountant at a Florida Salvation Army (SA) (救世军) thrift shop, said that, fｏｒher, shopping at thrift shops is a way to help the environment."When my daughter was little, we looked at it as recycling," Akins said: "Also, why pay 30 dollars fｏｒa new coat when you can get another one fｏｒa lot less?"Akins said that the SA has shops all over the US－"some as big as department stores". All of the clothes are donated (捐赠), ａｎｄ　when they have a surplus (盈余), they\'ll have "stuff a bag" specials, where customers can fill a grocery sack with clothes fｏｒonly 5 ｏｒ10 dollars.Julia Stocum, 22, points out, however, that the huge amount of second - hａｎｄ　clothing in the US is the result of American wastefulness."I\'d say that second - hａｎｄ　stores are the result of our wasteful, materialistic culture," said Slocum, who works fｏｒa pro - conservation organization, the center of a New American Dream. "Thrift shops prevent waste from going to landfills (垃圾填埋场), They give clothing a second life ａｎｄ　provide cheaper clothing fｏｒthose who can\'t afford to buy new ones ａｎｄ　generate (创造) income fｏｒcharities. They also provide a way fｏｒthe wealthy ａｎｄ　middle classes to shed (摆脱) the guilt fｏｒtheir level of consumption."Thrift shops can do everything EXCEPT ____【单选题】

A.give clothing a second life.

B.generate income fｏｒcharities.

C.provide cheaper clothes fｏｒthe poor.

D.stop rich people from wasting money.

正确答案:D

答案解析:本题有一定难度，需要认真阅读文章，答案依据在文章最后一段。最后一段谈到，旧货店给了服装二次生命，给那些买不起新衣服的人提供便宜衣服，还把一些收入捐给慈善机构，但没有提到阻止富人浪费钱，所以答案是D。

3、Travel Across AfricaFｏｒsix 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 fｏｒhours. 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 fｏｒa 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.Daniel ａｎｄ　Sophia drove slowly through the barren desert.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:本题较难，有相当数量考生做错了。本题的关键词和信号词是shot through，和barren，好多考生没有认真体会shoot的引申意思，shoot除了有“射击，拍摄”等意思外，还有一个引申意思“飞驰，飞快移动”，该题的一个出题点是确认代词we在文章中的指代意义，另一个出题点是理解单词shot在文章中的意义。考生要注意重点研究。

4、Three Ways to Become More CreativeMost people believe they don\'t have much imagination. They are wrong. Everyone has imagination, but most of us, once we become adults, forget how to access it. Creativity isn\'t always connected with great works of art ｏｒideas. People at work ａｎｄ　in their free time routinely think of creative ways to solve problems. Maybe you have a goal to achieve, a tricky question to answer ｏｒyou just want to expａｎｄ　your mind! There are three techniques to help you.This technique involves taking unrelated ideas ａｎｄ　trying to find links between them. First, think about the problem you have to solve ｏｒthe job you need to do. Then find an image, word, idea ｏｒobject, fｏｒexample, a candle. Write down all the ideas/words associated with candles, light, fire, matches, wax, night, silence, etc. Think of as many as you can. The next stage is to relate the ideas to the job you have to do. So imagine you want to buy a friend an original present; you could buy him tickets to a match ｏｒtake him out fｏｒthe night. Imagine that normal limitations don\'t exist. You have as much time/space/money, etc. as you want. Think about your goal ａｎｄ　the new possibilities. If, fｏｒexample, your goal is to learn to ski (滑雪), you can now practice skiing every day of your life (because you have the time ａｎｄ　the money). Now adapt this to reality. Maybe you can practice skiing every day in December, ｏｒevery Monday in January.Look at the situation from a different point of view. Good negotiators (谈判者) use this technique in business, ａｎｄ　so do writers. Fiction writers often imagine they are the characters in their books. They ask questions: what does this character want? Why can\'t she get it? What changes must she make to get what she wants? What does she dream about? If your goal involves other people, put yourself "in their shoes". The best fishermen think they are the fish!According to the passage, when we become adults ____.【单选题】

A.we can still learn to be more creative

B.most of us are no longer creative

C.we are not as imaginative as children

D.we are unwilling to be creative

正确答案:A

答案解析:本题难度不大，不要先看选项，吃透题干意思，回到原文定位，答案就在文章开头：Most people believe they don\'t have much imagination. They are wrong. Everyone has imagination, but most of us, once we become adults, forget how to access it. 句意不难理解，选项里creative替换了原文的imagination，最佳答案是A。

5、African wild dogFinding a babysitter while you go out to work is, fｏｒexample, an inconvenience. Fｏｒthe 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 ｏｒthe babysitting suffers, ｏｒthe 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 ｏｒfewer 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. "Poｏｒreproduction 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 spotted hyena is on the verge of extinction.【单选题】
