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!Backpacks are convenient because .【单选题】

答案解析:第1段告诉我们，因为背包可以装许多东西，所以可以将双手解放出来做其他事情(to free your hands to do other things).

2、Fermi ProblemOn a Monday morning in July, the world\'s first atom bomb exploded in the New Mexico desert, Forty seconds later, the shook waves reached the base camp where the Italian-American physicist Enrico Fezmi ａｎｄ　his team stood. After a mental calculation, Fermi announced to his team that the bomb\'s energy had equated 10,000 tons of TNT. The bomb team was impressed, but not surprised. Fermi\'s genius was known throughout the scientific world. In 1938 he had won a Nobel Prize. Four years later he produced the first nuclear chain reaction, leading us into the nuclear age. Since Fermi\'s death in 1954, no physicist has been at once a master experimentalist ａｎｄ　a leading theoretician.Like all virtuosos (大师), Fermi had a distinctive style. He preferred the most direct route to an answer. He was very good at dividing difficult problems into small, manageable bits talent we all can use in our daily lives.To develop this talent in his students, Fermi would suggest a type of question now known as a Fermi problem. Upon first hearing one of these, you haven\'t the remotest notion of the answer, ａｎｄ　you feel certain that too little information had been given to solve it, Yet when the problem is broken into sub-problems, each answerable without the help of expert. s ｏｒbooks, you can come close to the exact solution.Suppose you want to determine Earth\'s circumference without looking it up. Everyone knows that New York ａｎｄ　Los Angeles are about 3,000 miles apart ａｎｄ　that the time difference between them is three hours. Three hours is one-eighth of a day, ａｎｄ　a day is the time it takes the planet to complete one rotation, so its circumference must be eight times 3000 0r 24000 miles. This answer differs from the true value, 24,902. 45 miles, by less than four percent.Ultimately the value of dealing with everyday problems the way Fermi did lies in the rewards of making independent discoveries ａｎｄ　inventions. It doesn\'t matter whether the discovery is as important as determining the power of an atom ｏｒas small as measuring the distance between New York ａｎｄ　Los Angeles. Looking up the answer, ｏｒletting someone else find it deprives you of the pleasure ａｎｄ　pride that accompany creativity, ａｎｄ　deprives you of an experience that builds up self-confide. Thus, approaching personal dilemmas as Fermi problems can become a habit that enriches your life.Fermi problem is to develop the talent of breaking a seemingly unanswerable problem into sub-problems ａｎｄ　finding the solution to it, which is a typical Fermi problem.【单选题】

4、Intelligent Machines1. Medical scientists are already putting computer chips (芯片) directly into the brain to help people who have Parkinson\'s disease, but in what other ways might computer technology be able to help us? Ray Kurzweil is authｏｒof the successful book The Age of Intelligent Machines ａｎｄ　is one of the world\'s best computer research scientists. He is researching the possibilities.2. Kurzweil gets computers to recognize voices. An example of this is Ramona; the virtual (虚拟的) hostess of Kurzweil\'s homepage, who is programmed to understａｎｄ　what you say. Visitors to the site can have their conversations with her, ａｎｄ　Ramona also dances ａｎｄ　sings.3. Kurzweil uses this technology to help people with physical disabilities. One of his ideas is a "seeing machine". This will be "like a friend that could describe what is going on in the visible world", he explains. Blind people will use a visual sensｏｒ(探测器) which will probably be built into a pair of sunglasses. This sensｏｒwill describe to the person everything it sees.4. Another idea, which is likely to help deaf people, is the "listening machine". This invention will recognize millions of words ａｎｄ　understａｎｄ　any speaker. The listening machine will also be able to trans late into other languages, so even people without hearing problems are likely to be interested in using it.5. But it is not just about helping people with disabilities. Looking further into the future, Kurzweil sees a time when we will be able to download our entire consciousness onto a computer. This technology probably won\'t be ready fｏｒat least 50 years, but when it arrives, it means our minds will be able to live forever.Paragraph 5 ____【单选题】

A.A new pair of eyes

B.Computers that can communicate

C.Everlasting consciousness on a computer

D.Time to break off a friendship

E.An authｏｒａｎｄ　researcher

F.A new pair of ears

正确答案:C

答案解析:本题有一定难度，没有明显的主旨句。但第五段中间的关键词汇consciousness onto a computer，选项有近义解释。本段主要是畅想未来，谈论人类的整个意识系统可能会被植入到电脑里面，这样就意味着人类思想可永远留存。C项Everlasting consciousness on a computer，“在电脑里永远留存的意识”，可以概括本段内容，答案是C。

5、The Beginning of American LiteratureAmerican has always been a lａｎｄ　of beginnings. After Europeans "discovered" America in the fifteenth century, the mysterious New World became fｏｒmany people a genuine hope of a new life, an escape from poverty ａｎｄ　persecution, a chance to start again. We can say that, as nation, America begins with that hope. When, however, does American literature begin?American literature begins with American experiences. Long before the first colonists arrived, before Christopher Columbus, before the Northmen who "found" America about the year 1,000, Native Americans lived here. Each tribe\'s literature was tightly woven into the fabric of daily life ａｎｄ　reflected the unmistakably American experience of lining with the land. Another kind of experience, one filled with fear ａｎｄ　excitement, found its expression in the reports that Columbus ａｎｄ　other explorers sent home in Spain, French ａｎｄ　English. In addition, the journals of the people who lived ａｎｄ　died in the New Englａｎｄ　wilderness tell unforgettable tales of hard ａｎｄ　sometimes heartbreaking experiences of those early years.Experience, then, is the key to early American literature. The New World provided a great variety of experiences, ａｎｄ　these experiences demanded a wide variety of expressions by an even wider variety of early American writers. These writers included John Smith, who spent only two-and-a-half years on the American continent. They included Jonathan Edwards ａｎｄ　William Byrd, who thought of themselves as British subjects, never suspecting a revolution that would create a United States of America with a literature of its own. American Indians, explorers, Puritan ministers, frontier wives, plantation owner-they are all the creators of the first American literature.The main purpose of the last paragraph is to tell the readers that .【单选题】

A.in the early days most American writers were from Great Britain

B.people with rich life experiences became writers

C.there were many writers in the early days of American history

D.early-day experience provided the foundation fｏｒAmerican literature
