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 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!Backpacks are convenient because .【单选题】

2、Longer Lives Are Happier Lives1 In recent years, scientists have been studying ways to change the body\'s chemistry to reduce the signs and effects of aging.2 0ne group of researchers in Britain has performed experiments on a kind of worm. They have managed to increase the worm\'s normal life span of 20 days by up to 400%. They hope that they will be able to use this research to help humans live longer. However, this is a long way in the future. Another disadvantage is that when (or if) the new technology is successfully developed, it will probably be very expensive. The chance to live longer will only be available to a very few, very rich people.3 Another group of scientists is studying people who have reached a very old age. They believe that this may show what has kept these people healthy and alive for so long. So, if we look at people who have lived into very old age, what do they have in common? Usually they have led a physically active life. This does not mean going to a gym or running ten miles every day. Simple, enjoyable activities like walking seem to be more likely to keep you healthy. Very old people also eat a good, varied diet. Simple foods like vegetable, rice, pasta and fish are the best.4 However, there may be one thing even more important than physical factors like diet and exercise. Research shows that personality, and the way a person thinks, play an important part in how long they will live. People who live into very old age always seem to enjoy life. They have a sense of humor and get satisfaction from simple things. They do not constantly think about the past, but are interested in the present and the future. They do not let life get boring, but have interests and hobbies which keep their minds active and they are open to new ideas. One Japanese man who lived to be 120 commented that the secret of his long life was "not worrying". To express it simply, people who are happy and positive about life are more likely to live longer.5 So, eat well, exercise well, and enjoy life, and you will have a good chance of living to a healthy, happy old age.Paragraph 2 ____【单选题】

A.How to live happy old age

B.Disadvantages of the project

C.The study of old people

D.Personality and other mental factors are more important

E.Worms live longer than humans

F.Live simple lives

正确答案:B

答案解析:由“Another disadvantage is…”可以看出一共说了两个弊端，以此说明想让人们活的长久的这个实验是不可行的。

3、We had a long conversation about her parents.【单选题】

A.speech

B.question

C.talk

D.debate

正确答案:C

答案解析:关于她父母我们谈了很久。本题难度不大，考查的是基本意义，干扰项干扰不大。conversation和talk都有“谈话”的意思，是近义词，A项指“讲话”，D项指“辩论”，和答案意义差异大，最佳答案是C。

4、Desirable Qualities in a TeacherHere I want to try to give you an answer to the question: What personal qualities are desirable in a teacher? Probably no two people would draw up exactly similar lists, but I think the following would be generally accepted.First, the teacher\'s personality should be pleasantly live and attractive. This does not rule out people who are physically plain, or even ugly, because many such have great personal charm. I would say that excludes all of dull or purely negative personality. I still stick to what I said in my earlier book: that school children probably suffer more from bores than from brutes.Secondly, it is not merely desirable but essential for a teacher to have a _____ capacity for sympathy in the literal meaning of that word; a capacity to tune in to the minds and feelings of other people, especially, since most teachers are school teachers, to the minds and feelings of children. Closely related with this is the capacity to be tolerant not indeed, of what is wrong, but of frailty （脆弱) and immaturity of human nature which induce people, and again especially children, to make mistakes.Thirdly, I hold it essential for a teacher to be both intellectually and morally honest. This does not mean being a plaster saint. It means that he will be aware of his intellectual strengths.【单选题】

A.genuine

B.True

C.great

D.general

正确答案:C

答案解析:genuine（真正的），此句意思是“教师不仅需要而且也必须拥有同情心——真正意义上的同情心。”

5、Houses of the FutureWhat will houses be like after thirty years? No one really knows, but architects are trying to predict. What will our home be like then?Future houses will have to be flexible. some of us will be working from home. So we will have to be able to use areas of the house for work for part of the day and for living for the rest. Families grow and change with children arriving, growing up and leaving home. The house of the future will have to grow and change with the family. Nothing will be as fixed as it is now. The house will always be changing to meet changing needs.Everyone agrees that after 30 years we will be living in "intelligent" houses. We will be able to talk to our kitchen machines and discuss with them what to do. Like this: "We\'ll be having a party this weekend. What food shall we cook?" ____ We will be able to leave cooking to the machines, just tasting things from time to time to check.The house of the future will be personal and each house will be different. You will be able to change the color of the wall easily. You won\'t have to paint them and you\'ll be able to tell the wall to change the color! And if you don\'t like the color today, you will be able to have a new one. The only thing you won\'t be able to do is move the house somewhere else!【单选题】

A.You will be able to change the color of the wall easily.

B.The only thing you won\'t be able to do is move the house somewhere else!

C.And the machine will tell us what food we will have to buy and how to cook it.

D.What will our home be like then?

E.The house of the future will have to grow and change with the family.

F.The kids might take their bedrooms with them as they leave.

6、A Country\'s Standard of LivingThe "standard of living" of any country means the average person\'s share of the goods and services the country produces. A country\'s standard of living, therefore, depends first on its capacity to produce wealth. "Wealth" in this sense is not money, for we do not live on money but on things that money can buy: "goods such as food and clothing", and "services" such as transport and entertainment.A country\'s capacity to produce wealth depends upon many factors most of which have an effect on one another. Wealth depends to a great extent upon a country\'s natural resources. Some region of the world are well supplied with coal and minerals, and have fertile (肥沃的) soil and a favorable climate, other regions possess none of them.Next to natural resources comes the ability to turn them to use, China is perhaps as rich as the USA in natural resources, but suffered for many years from civil and external wars, For this and other reasons it was unable to develop her resources. Sound and stable political conditions, and freedom from foreign invasions, enable a country to develop its natural resources peacefully and steadily, to produce more ____ than other country.A country\'s standard of living does not only depend upon the wealth that is produced and consumed within its own borders, but also upon what is directly produced through international trade. For example, Britain\'s wealth in foodstuffs and other agricultural products would be much less if she had to depend only on those grown at home. Trade makes it possible for her surplus (剩余的) manufactured goods to be traded abroad for the agricultural products which would otherwise be lacking. A country\'s wealth is, therefore, much influenced by its manufacturing capacity, providing that other countries can be found ready to accept its manufactures.【单选题】

A.wealth

B.report

C.effect

D.result

正确答案:A

答案解析:本题难度不大，干扰项干扰不强。可以先看选项，得到信息提示，结合原文，很明显，此处要使用wealth，“财富”，最佳答案是A。

7、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was -91℃ which occurred in Antarctica in 1983.We encounter an interesting situation when we discuss temperatures in space Temperatures in Earth orbit actually range from about +120℃ to -120℃. The temperature depends upon whether you are in direct sunlight or shade, Obviously, -120℃ is colder than our body can safely endure. Thank NASA science for well-designed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our area of the solar system . Obviously, it is hotter closer to the Sun and colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about -210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is -273℃, at which atoms do not move. Two scientists, whose names are Cornell and Wieman, have successfully cooled down a gas temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 for their work not a discovery in this car.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about particles we now call photons. Bose had trouble convincing Other scientists to believe so he contacted Albert Einstein. Einstein\'s calculations helped him theorize would behave as Bose thought but only at very cold temperatures.Scientists have also discovered that ultra-cold atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time(d=vxt). With the long distances involved in space _____ to know time as accurately as possible to get accurate distance.【单选题】

A.travel

B.research

C.walk

D.station

正确答案:A

答案解析:从地球飞向其他星球的宇宙航程很长，计时越精确，测算宇宙飞行器的即时距离就越精确。本段讲的是精确计时对宇宙航行的重要性，所以选travel是正确的。本题不能选 walk，因为space walk是“太空行走”，指的是宇航员离开飞船在宇宙空间中活动，与space travel是两个不同的概念。

8、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 ____ 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 common: 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.even if

B.as if

C.as

D.even

正确答案:A

答案解析:本题难度不大，从句中上下文来看，此处是需要“即使”的含义，选项里只有A是“即使”的意思，是答案。

9、Woman workThough some people have suggested that women should return to housework in order to leave ____ jobs for men, the idea has been rejected by both women and men in public opinion polls.Lately some union officials have suggested that too many women are employed in types of work more suitable for men and that women should step aside to make way for unemployed young men. They argue that women, especially women in their childbearing years,actually delay economic development and result in productivity, poor quality and inefficiency.To solve the problem, they suggested that working women stay at home while their husbands or brothers were given double wages. They argue that under these circumstances, families would remain their same level of income, and women could run the house and raise children much better,The suggestion, however , has been flatly rejected by 9 0ut of 10 people polled .Some other people have suggested another way called "phased employment" theory. The theory suggests that a woman worker take leave from her job when she is seven months pregnant and stay off the job until her baby reaches the age of 3. It suggested that women on leave receive 75 percent of their normal salary and be allowed to return to work after the three-year period. This will benefit children, women, their families and the society and it definitely seems to be more acceptable than the suggestion that women return to their homes forever.【单选题】

A.more

B.fewer

C.much

D.less

正确答案:A

答案解析: job是可数名词，因此要排除C和D，根据上文“建议女人回家做家务”，会给男人留下更多的工作，因此排除B。

10、One-Room SchoolsOne-room schools are part of the heritage of the United States, and the mention of them makes people feel a longing for "the way things were." One - room schools are an endangered species (种类), however. For more than a hundred years, one - room schools have been systematically shut down and their students were sent away to centralized schools. As recently as 1930 there were 149,000 one - room schools in the United States. By 1970 there were 1,800. Today, of the nearly 800 remaining one - room schools, more than 350 are in Nebraska. The rest are spread through a few other states that have on their road maps wide - open spaces between towns.Now that there are hardly any left, educators are beginning to think that maybe there is something yet to be learned from one - room schools, something that served the pioneers that might serve as well today. Progressive educators have come up with new names like "peer - group teaching" and "multi - age grouping" for educational procedures that occur naturally in the one - room schools. In a one - room school the children teach each other because the teacher is busy part of the time teaching someone else. The fourth grader can work at the fifth grade level in math and the third grade level in English without the bad name associated with being left back or the pressures of being skipped (超过) ahead. A youngster with a learning disability can find his or her own level without being separated from other pupils. A few hours in a small school that has only one classroom and it becomes clear why so many parents feel that one of the advantages of living in Nebraska is that their children have to go to a one - room school.One - room schools are in danger of disappearing because ____. 【单选题】

A.there has been a trend towards centralization

B.they cannot get top students

C.they exist only in one state

D.children have to teach themselves

正确答案:A

答案解析:本题有一定的难度，考生不太好定位，需要认真读第一段找答案。第一段第三句谈到，一百多年来，大教室学校逐渐被关闭，学生被统一分到政府的集中化学校，回来看选项，A是近义解释，是最佳答案。做本题时可以先看选项，得到信息提示。
