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 ______. Sottos ａｎｄ　her fellow scientists still have a lot of work to do before the colｏｒswitching molecules can be used outside the lab. 【单选题】

A.dangerous

B.useless

C.helpful

D.important

正确答案:B

答案解析:前后文是转折关系，前面说到是问题，又有warning system的说法，应该是使之失效的意思，选useless。

2、The policeman wrote down all the details of the accident.【单选题】

A.secrets

B.particulars

C.benefits

D.words

正确答案:B

答案解析:题干大意：警察写下了事故的所有的细节。画线词details：细节。选项中，particulars：细节。secrets：秘密。如：One I can tell my secrets to. 一个我能告诉秘密的人。benefits：收益。如：But he sees other benefits, too. 但他也看到了其他好处。words：话语。如：In other words, current prices reflect this level of supply. 换言之，当前的价格反映了这种供应水平。

3、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 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. " Children born today will have reached the age of 43."【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:A

答案解析:本题前面是主题句：But there have been some big mistakes in this field，too。主题句后面的句子应该是扩展句，点出big mistakes的内容或举例说明big mistakes。选项A就是big nustakes的一个例子。本题后面的句子说许多股票大跌，投资者破产，证明了预测的错误。所以选项A是正确的。

4、Obviously these people can be relied on in a crisis.【单选题】

A.lived on

B.depended on

C.believed in

D.joined in

正确答案:B

答案解析:显然这些人在危机关头值得依靠。本题有一定难度，考查的是基本意义，C项的干扰最大，有些考生因受汉语思维影响而选了C，rely on和depend on都有“依靠”意思，是近义词，常用过去式，C项believe in指“相信”，和答案意义有差异，最佳答案是B。

5、Illinois has produced writers such as Carl Sandburg, gangsters such as Al Capons, ａｎｄ　architects such as Louis Sullivan. 【单选题】

A.violent criminals

B.politicians

C.musicians

D.industrialists

正确答案:A

答案解析:violent criminal：暴力罪犯和gangster（匪徒、歹徒）意思相近；politician:政客、政治家；musician：音乐家；industrialist：工业家。

6、An Intelligent CarDriving needs sharp eyes, keen ears, quick brain, ａｎｄ　coordination between hands ａｎｄ　the brain. Many human drivers have all. these ａｎｄ　can control a fast-moving car. But how does an intelligent car control itself ?There is a virtual driver in the smart car. This virtual driver has "eyes," "brains", "hands" ａｎｄ　"feet", too. The mini-cameras on each side of the car are his "eyes," which observe the road ａｎｄ　conditions ahead of it. They watch the traffic to the car\'s left ａｎｄ　right. There is also a highly automatic driving system in the car. It is the built-in computer, which is the virtual driver\'s "brain". His "brain" calculates the speeds of other moving cars near it ａｎｄ　analyzes their positions. Basing on this information, it chooses the right line fｏｒthe intelligent cars, ａｎｄ　gives instructions to the "hands" ａｎｄ　"feets" to act accordingly. In this way, the virtual driver controls his car. What is the virtual driver\'s best advantage? He reacts rapidly. The mini-cameras are sending images continuously to the "brain". It completes the processing of the images within 100 milliseconds. However, the world\'s best driver at least needs one second to react. Besides, when he takes action, he needs one more second. The virtual driver is really wonderful. He can reduce the accident ______. considerably on expressway. In this case, can we let him have the wheel at any time ａｎｄ　in any place? Experts warn that we cannot do that just yet. His ability to recognize things is still limited. He can now only drive an intelligent car on expressways. 【单选题】

A.count

B.amount

C.digit

D.rate

正确答案:D

答案解析:直接借助空白所在的局部搭配（事故……）判断答案是D（事故发生率）。

7、Breastfeeding Can Cut Cardiovascular RiskBreastfeeding can reduce the risk of a heart attack ｏｒstroke later in life ａｎｄ　could prevent hundreds of thousands of deaths each year, researchers said on Friday. Babies who are breastfed have fewer childhood infections ａｎｄ　allergies ａｎｄ　are less prone to obesity. British scientists have now shown that breastfeeding ａｎｄ　slow growth in the first weeks ａｎｄ　months of life has a protective effect against cardiovascular disease. "Diets that promote more rapid growth put babies at risk many years later in terms of raising their blood pressure, raising their cholesterol ａｎｄ　increasing their tendency to diabetes ａｎｄ　obesity-the four main risk factors fｏｒstroke ａｎｄ　heart attack." said ProfessｏｒAlan Lucas of the Institute of Child Health in London. "Our evidence suggests that the reason why breast-fed babies do better is because they grow more slowly in the early weeks."Lucas said the effects of breastfeeding on blood pressure ａｎｄ　cholesterol later in life are greater than ______ adults can do to control the risk factors fｏｒcardiovascular disease, other than taking drugs. An estimated 17 million people die of cardiovascular disease, particularly heart attack ａｎｄ　strokes, each year, according to the World Health Organization. Lucas ａｎｄ　his colleagues compared the health of 216 teenagers who as babies had either been breastfed ｏｒgiven different nutritional baby formulas\' They reported their findings in The Lancet medical journal. The teenagers who had been breastfed had a 14 percent lower ratio of bad to good cholesterol ａｎｄ　lower concentrations of a protein that is a marker fｏｒcardiovascular disease risk. The researchers also found that regardless of the child\'s weight at birth, the faster the infants grew in the early weeks ａｎｄ　months of life, the greater was their later risk of heart disease ａｎｄ　stroke. The effect was the same fｏｒboth boys ａｎｄ　girls. "The more human milk you have in the newborn period, the lower your cholesterol level is, the lower your blood pressure is 16 years later, "Lucas said. 【单选题】

A.which

B.that

C.something

D.anything

正确答案:D

答案解析:根据语法结构和句意判断D（任何事情）合适。

8、People can not understａｎｄ　the killer\'s motive to commit murder. 【单选题】

A.reason

B.expectation

C.argument

D.target

正确答案:A

答案解析:reason:理由、原因、动机，与原句中motive的意思相近；expectation：期望、展望、期待；argument:争论、辩论、论据；target：靶子。

9、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 (南极洲) 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 ｏｒshade. Obviously, -120℃ is colder than our body can safely endure. Thank NASA science fｏｒwell, de signed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our areal 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 ______ 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 to a temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 fｏｒtheir work, not a discovery, in this case.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about special light particles we now call photons (光子). Bose had trouble convincing other scientists to believe his theory, so he contacted Albert Einstein. Einstein\'s calculations helped him theorize that atoms would behave as Bose thought—but only at very cold temperatures.Scientists have also discovered that ultra - cold(超冷) 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 4 ( d = v×t). With the long distances involved in space travel, we need to know time as accurately as possible to get accurate distance.【单选题】

A.impossible

B.interesting

C.reasonable

D.necessary

正确答案:A

答案解析:本题有一定难度，考查词义辨析，干扰项有一定的干扰。根据上下文逻辑，文章此处是说“我们从课本上学到不可能有低于绝对温度的温度出现”，答案是A。

A.any

B.each

C.some

D.every

正确答案:D

答案解析:本题有一定难度，考查不定代词every的用法，干扰项有一定的干扰。根据上下文逻辑，文章此处是说“……每六百万年仅差一秒”，each后面不能跟复数名词，因此最佳答案是D。
