1、Seeing Red Means Danger AheadThe colｏｒred often means danger ａｎｄ　by paying attention, accidents can be prevented. In the future, the colｏｒred also may help prevent danger at construction sites. Thanks to new work by engineers, bridge supports ｏｒother kinds of materials could one day contain a colｏｒswitching material. It will turn red before a structure collapses ｏｒfalls apart. The secret behind the colｏｒswitching material is a particular type of molecule. A molecule is aｇｒｏｕｐof atoms held together by chemical bonds. Molecules come at all shapes ａｎｄ　sizes, ａｎｄ　make up everything. You can see, touch ｏｒfeel. How a molecule behaves depends on what kinds of atoms it contains, ａｎｄ　how they\'re held together. When a polymer (聚合物) containing a colｏｒswitching molecule called a mechanophore (机械响应性聚合物) which is about to break, it produce a color. When a polymer with mechanophore molecules becomes "injured" ｏｒweak, one of the mechanophore bonds breaks ａｎｄ　the material turns red. "It\'s a really simple detection method. "says Nancy Sottos, one of the scientists who worked on the project. Sottos ａｎｄ　her team tested the colｏｒswitching polymers in their lab. The test results proved encouraging. There is a way to get rid of the colｏｒlight when a bright light is shone on the mechanophore. The broken bond is fixed ａｎｄ　the red colｏｒdisappears. This "self-healing" may be a problem fｏｒengineers. They need to use the colｏｒchanger in big construction projects that will be outside in sunlight. ａｎｄ　sunlight will make the mechanophore\'s warming system useless. Sottos ａｎｄ　her fellow scientists still have ______ work to do before the colｏｒswitching molecules can be used outside the lab. 【单选题】

A.a part of

B.a type of

C.a lot of

D.a part of

正确答案:C

答案解析:意思应该是在变色分子可用于实践之前，Sottos和她的团队还需要做很多的努力。所以选a lot of合适。

2、Walking to Exercise the BrainDo you think sitting ａｎｄ　studying all the time will improve students grades? Think again. Getting some exercise may help, too.New research with older people suggests that taking regular walks helps them pay attention better than if they didn\'t exercise.Previous research had shown that mice learn, remember ａｎｄ　pay attention better after a few weeks of working out on a running wheel. Mice that exercise have greater blood flow to the brain than those who don\'t. Their brain cells also make more connections.Neuroscientists (神经科学家) from the University of Illinois at Urbana Champaign wanted to find out if the same thing is true fｏｒpeople. First, they measured the physical fitness of 41 adults, ages 58 to 77, after each person walked I mile. Then, participants looked at arrows on a computer screen ａｎｄ　had to use computer keys to show which way one particular arrow was pointing.Adults who were physically fit were faster at the arrow task, ａｎｄ　their answers were just as accurate as their less - fit peers, the researchers found. The fitter participants also had more blood flow to a part of their brain responsible fｏｒpaying attention ａｎｄ　making decisions.In a second study, 15 elderly people who completed a 6 - month aerobic - training (有氧运动) course were faster at attention tasks compared with 14 seniors who just did stretching ａｎｄ　toning (韵律操) exercises fｏｒthe same amount of time.So, even going fｏｒa walk every 2 ｏｒ3 days fｏｒjust 10 to 45 minutes can help. That should be good news fｏｒthe elderly.The effects of exercising on the brains of younger people haven\'t been studied yet. Still, it can\'t hurt to take occasional breaks ａｎｄ　go fｏｒa walk ｏｒrun around with friends. Whatever you do, though, don\'t try to read ａｎｄ　walk at the same time. You could end up hurting yourself!The first study on 41 elderly people found ______.【单选题】

A.the less - fit participants did arrow tasks faster

B.the fitter participants did arrow tasks faster

C.the less - fit participants gave more accurate answers

D.the fitter participants gave more accurate answers

正确答案:B

答案解析:本题有一定难度，需要认真阅读文章。答案依据在文章第五段。带着题干信息词回到文章定位。第五段第一句谈到，研究者发现身体健康的成年人完成箭头测试的速度更快，回来看选项，很明显，B是近义解释，是答案。

3、Don\'t Rely on Plankton to Save the PlanetEncouraging plankton growth in the ocean has been touted by some as a promising way to remove carbon dioxide from the atmosphere. ______Adding iron to patched of ocean can make plankton bloom temporarily. The microscopic organisms suck up dissolved carbon dioxide from the water, which in turn is replaced by carbon dioxide from the air. As plankton die ａｎｄ　settle on the ocean floor, their carbon is supposedly locked up in the seabed.Jorge Sarmiento from Princeton ａｎｄ　his colleagues developed a complex computer model to analyze how factors such as ocean chemistry ａｎｄ　water circulation would affect the process if 160,000 square kilometers of ocean were seeded with iron fｏｒa month. They found that 100 years later only between 2 ａｎｄ　13 percent of the extra carbon that was originally taken up plankton had actually been removed from the atmosphere.In their scenario, which covers an area 10 times as big as the largest experiment of this kind ever proposed, fertilizing the ocean removes 1 million tons of carbon from the atmosphere just 0.2 percent of the carbon dioxide humankind spews out each month. Rough estimates in the past have predicted similarly disappointing results."These are newer ａｎｄ　better models," says Sallie Chisholm, an environmental engineer from the Massachusetts Institute of Technology."Butthe take-home message is the same. Ocean fertilization is not the answer to global warming."【单选题】

A.Its opponents argue, however, that it will stop global warming.

B.Its opponents fear that will damage the marine ecosystem, ａｎｄ　now a computer model shows that the trick would also be remarkably inefficient.

C.As plankton die ａｎｄ　settle on the ocean floor, their carbon is supposedly locked up in the seabed.

D.They found that 100 years later only between 2 ａｎｄ　11 percent of the extra carbon that was originally taken up plankton had actually been removed from the atmosphere.

E."These are newer ａｎｄ　better models,"

F.Ocean fertilization is not the answer to global warming.

正确答案:B

答案解析:前句的句意（可以直接借助句子中的核心结构判断句子大意）：“一些人鼓励浮游生物在海洋里生长，认为这有希望从大气中去除二氧化碳”，B中的opponents fear和空白前句中的some. . . encourage形成语意对比。

4、A special educationVideodisc holds great promise of helping to meet the needs of American schoolchildren who have problems seeing, hearing, speaking, ｏｒsocializing. Almost eleven percent of the students aged 3-21 in this country have an impairment that affects their ability to benefit from a regular education program. Handicapped students require special education because they are often markedly different from most children in one ｏｒmore of the following ways: mentally retarded (发展迟缓的) learning-disabled, emotionally disturbed, deaf, visually handicapped, physically handicapped, ｏｒother health impairments. The education of these handicapped children is rewarding but challenging. A special education student usually needs a longer period of time to acquire information. Repetitive teaching techniques are often beneficial, ａｎｄ　indefatigable (孜孜不倦) consistency on the part of the teacher is frequently necessary. Interactive videodisc courseware has characteristics that can be capitalized upon to meet the challenges that special education poses. A videodisc program is infinitely patient. Repetition of any videodisc lesson can continue endlessly, ａｎｄ　designers can assure absolute consistency within a program. Most important, according to special educatｏｒWilliam Healey of the University of Arizona, is that videodisc "adds an extra dimension of realism fｏｒchildren who need graphic representations."Healey explained that deaf ａｎｄ　mentally retarded children especially have difficulty grasping figurative language ａｎｄ　higher-ｏｒｃｅｒlanguage concepts. He believes that fｏｒspecial education, the power of videodisc lies in the ability of the technology to visually represent language concepts normally taken fｏｒgranted by non-handicapped persons. Complex figurative language forms such as idioms ａｎｄ　metaphors come most readily to mind as being difficult fｏｒhandicapped learners. A videodisc courseware is beneficial to those who have study difficulties because______【单选题】

A.its fancy design is very attractive

B.it allows the user to go back to where he wants to restudy

C.the content of it is healthy ａｎｄ　promising

D.it is developed by university professors

正确答案:B

答案解析:文章第2段第2句指出，残疾儿童往往需要老师不厌其烦地反复教导，接着谈到互动式影碟课件可以不断地重放课程，由此推断，影碟课件使学习有困难的学生能够回放他们想再次学习的课程，故选B。

5、Cloning: Future Perfect?1 A clone is an exact copy of a plant ｏｒanimal produced from any one cell. Since Scottish scientists reported that they had managed to clone a sheep named Dolly in 1997, research into cloning has grown rapidly. In May 1998, scientists in Massachusetts managed to create two identical calves using cloning technology. A mouse has also been cloned successfully. But the debate over cloning humans really started when Chicago physicist Richard Seed made a surprising announcement: "We will have managed to clone a human being within the next two years," he told the world. 2 Seed\'s announcement provoked a lot of media attention, most of it negative. In Europe, nineteen nations have already signed an agreement banning human cloning ａｎｄ　in the US the President announced: "We will be introducing a law to ban human cloning ａｎｄ　many states in the US will have passed anti-cloning laws by the end of the year". 3 Many researchers are not so negative about cloning. They are worried that laws banning human cloning will threaten important research. In March, The New Englａｎｄ　Journal of Medicine called any plan to ban research on cloning humans seriously mistaken. Many researchers also believe that in spite of attempts to ban it, human cloning will have become routine by 2010 because it is impossible to stop the progress of science. 4 Is there reason to fear that cloning will lead to a nightmare world? The public has been bombarded (轰炸) with newspaper articles, television shows ａｎｄ　films, as well as cartoons. Such information is often misleading, ａｎｄ　makes people wonder what on earth the scientists will be doing next. 5 Within the next five to ten years scientists will probably have found a way of cloning humans. It could be that pretty soon we will be able to choose the person that we want our child to look like. But how would it feel to be a clone among hundreds, the anti-cloners ask Pretty cool, answer the pro-cloners (赞成克隆的人). Paragraph 3____【单选题】

A.Strong Reactions

B.Anxiety about the Future of Cloning

C.The Right to Choose

D.WhatisCloning?

E.Arguments in Favｏｒof Cloning

F.A Common Sight

正确答案:E

答案解析:文章第3段主要讲一些科学家对克隆的正面反应，认为人们无法阻挡科技的进步。

正确答案:A

答案解析:前文一直提示分子变红色，所以在此情景下，选颜色是符合全文主题的。

7、The orangutanAmong all the animals, the ape is most like human beings. Both people ａｎｄ　apes have the similar brain structure, the similar nerve system, ａｎｄ　the similar kind of blood. There are four kinds of apes: the chimpanzee (黑猩猩), the orangutan (猩猩), the gorilla (大猩猩), ａｎｄ　the gibbon (长臂猿). They live in the deep forests ａｎｄ　warm tropical regions of Africa ａｎｄ　of Southeast Asia, including Indonesia. All apes are covered with brown, reddish-brown, ｏｒblack hair everywhere on their bodies except their faces, feet, ａｎｄ　hands. Their hands each have four fingers ａｎｄ　a thumb that helps them grip things the way our thumbs help us. But they also have a thumb on each foot instead of a big toe. Thus they can hold things with their feet also. Having short, weak legs, apes do not walk on the ground very much. However, their arms are very strong. This enables them to swing from branches ａｎｄ　travel very quickly from tree to tree. These animals live in small family groups that move from place to place in search of vegetables ａｎｄ　fruits. They also eat eggs, small animals, nuts, ａｎｄ　insects. When they are tired, they build nests in the trees. But they rarely sleep there fｏｒmore than a night ｏｒtwo. Then they move on to look fｏｒmore food. There are some differences among the following three kids of apes. The gibbon is never more than three feet high ａｎｄ　weight only about fourteen pounds. The gorilla grows to be six feet tall ａｎｄ　weight up to 600 pounds. The orangutan is smaller than the gorilla. It stands three to five feet tall ａｎｄ　weight up to 200 pounds. Chimpanzees are the smartest of all apes. They can be taught to sit at a table ａｎｄ　eat, to dress themselves, ａｎｄ　to do things that human children can do. The last paragraph tells us that____. 【单选题】

A.chimpanzees can do better than human children

B.chimpanzees can do many things that human children cannot do

C.human children can do many things that chimpanzees cannot do

D.the intelligence of chimpanzees is similar to that of human children

正确答案:D

答案解析:文章最后一段指出，黑猩猩是所有猿中最聪明的，可以做人类儿童能做的事情，由此推断，黑猩猩的智力与人类儿童的智力相似，故选D。

8、Looking to the FutureWhen a magazine fｏｒhigh-school students asked its readers what life would be like in twenty years, they said: Machines would be run by solar power. Buildings would rotate so they could follow the sun to take maximum advantage of its light ａｎｄ　heat. Walls would "radiate light" ａｎｄ　"change colｏｒwith the push of a buttons." Food would be replaced by pills. School would be taught "by electrical impulse while we sleep." Cars would have radar. Does this sound like the year 2000? Actually, the article was written in 1958 ａｎｄ　the question was, "what will life be like in 1978?". The future is much too important to simply guess about, the way the high school students did. So experts are regularly asked to predict accurately.By carefully studying the present, skilled businessmen, scientists, ａｎｄ　politicians are supposedly able to figure out in advance what will happen. But can they? One expert on cities wrote: Cities of the future would not be crowded but would have space fｏｒfarms ａｎｄ　fields. People would travel to world in "airbuses" all-weather helicopters carrying up to 200 passengers. When a person left the airbus station he could drive a coin-operated car equipped with radar. The radar equipment of cars would make traffic accidents "almost unheard off\'. Does that sound familiar? If the exert had been accurate it would, because he was writing in 1957. His subject was "The city of 1982". If the professionals sometimes sound like high-school students, it\'s probably because future study is still a new field. Here is an example fｏｒfuture study. Economic forecasting, ｏｒpredicting what the economy will do, has been around fｏｒa long time. But there have been some big mistakes in this field, too. In early 1929, most forecasters saw an excellent future fｏｒthe stock market. In October of that year, the stock market had its worst losses ever, ruining thousands of investors who had put their faith in financial foreseers. One forecaster knew that predictions about the future would always be subject to significant errors. In 1957, H. J. Rａｎｄ　of the Rａｎｄ　Corporation was asked about the year 2000, "Only one thing is certain," he answered. " ______"【单选题】

A.In early 1929, most forecasters saw an excellent future fｏｒthe stock market.

B.Children born today will have reached the age of 43.

C.Actually, the article was written in 1958 ａｎｄ　the question was, "what will life be like in 1978?"

D.So experts are regularly asked to predict accurately.

E.Scientists are 80 percent accurate in predicting the future.

F.The radar equipment of cars would make traffic accidents "almost unheard off\'.

正确答案:B

答案解析:最后一段是总结段，指出预测的不准确性。结束前用调侃的语气写道，要预测2000年将发生的事情，有一件事是不会预测错的：今天出生的婴儿到2000年是43岁(2000-1957=43)。

9、A number of theories have been proposed to explain the situation.【单选题】

A.suggested

B.tested

C.used

D.announced

正确答案:A

答案解析:有多种理论被建议用来解释目前形势。本题难度不大，干扰项干扰性不大，propose和suggest都有“建议”的意思，最佳答案是A。

10、A Star Is Born1 The VLT (Very Large Telescope) is the world\'s largest telescope ａｎｄ　is taking astronomers further back to the Big Bang than they ever thought possible. Located 2,600 meters up to the Chilean Andes, it has four huge mirrors, each about the size of a London bus. The VLT is so powerful it can spot a burning match 10, 000 kilometers away. 2 This astonishing power will allow astronomers to see events in space from the birth of stars to the collision of galaxies on the edge of the cosmos. The VLT is giving astronomers their best ever view of the cosmos. The power of the VLT to see the smallest detail at the furthest distances makes its designers amazed. 3 Take the case of Eta Carinae, one of the most explosive stars in the universe. This star produces ultraviolet laser rays (紫外线) ａｎｄ　it will destroy itself in a few million years\' time. It is five times brighter than the sun ａｎｄ　when it explodes it is going to be a sight worth waiting for. 4 But it is at distances of millions, even billions, of light years that the VLT really shows its power. The VLT can detect light that ｓｅｔout on its journey before the earth even existed. This gives astronomers their first ever detailed views of events that took place in the earliest days of the cosmos. 5 In other words, the VLT is a kind of a time machine. It takes astronomers back to a time when complete galaxies crashed into each other. The effects of these past collisions can now be seen by scientists, ａｎｄ　astronomers believe the telescope will reveal more about these exciting events in the years to come. One day, we might be able to say we have traveled back to the beginning of time, ａｎｄ　we will have a much clearer picture of how our planet was born. Paragraph 1____【单选题】

A.Events That Took place Before the Earth Existed

B.Power of the Telescope

C.Details of Eta Carinae

D.Invention of a Time Machine

E.Biggest Telescope

F.Ultraviolet Laser Rays

正确答案:E

答案解析:文章第1段主要介绍的是世界上最大的望远镜的大小，故E为正确答案。
