1、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? ______. 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. " 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:C
答案解析:第1段主要介绍对未来的预测。作者问读者,所列的各种高科技的发展的预测是不是会在2000年发生?本题所在的句子说,实际上有人预测在1978年会发生。根据这个上下文,选项C填入后,意思是连贯的。1958年写的文章预测20年之后的高科技的发展。
2、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 color- changing material. It will turn red before a structure collapses orfalls apart.The secret behind the color- changing material is a particular type of molecule (分子). A molecule is agroupof atoms (原子) held together by chemical bonds. Molecules come _____ 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 color- changing molecule called a mechanophore (机械响应性聚合物) is about to break, it produces 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 color- changing polymers in their lab. The test results proved encouraging.There is a way to get rid of the red colorlight. When a bright light is shone on the mechanophore, the broken bond is fixed and the red colordisappears. Thus "self - healing" may be a problem forengineers. They need to use the color- changer in big construction projects that will be outside, under sunlight. and sunlight will make the mechanophore\'s warning system useless.Sottos and her fellow scientists still have a lot of work to do before the color- changing molecules can be used outside the lab.【单选题】
A.for
B.in
C.from
D.at
正确答案:B
答案解析:本题有一定难度,干扰项有一定的干扰性,本题考查固定搭配come in,指“以……方式出来”,答案是B。
3、Why Would They Falsely Confess?Why on earth would an innocent person falsely confess to committing a crime? To most people, it just doesn\'t seem logical. But it is logical, say experts, if you understand what can happen in a police interrogation room.Under the right conditions, people\'s minds are susceptible to influence, and the pressure put on suspects during police grilling is enormous. "It\'s a little like somebody\'s working on them with a dental drill," says Franklin Zimring, a law professorat the University of California at Berkeley. "The pressure is important to understand, because otherwise it\'s impossible to understand why someone would say he did something he didn\'t do. The answer is: to put an end to an uncomfortable situation that will continue until he does confess."Developmental psychologist Allison Redlich recently conducted a laboratory study to determine how likely people are to confess to things they didn\'t do. In her experiment, participants were seated at computers and told not to hit the "alt" key, because doing so would crash the systems. The researchers then intentionally crashed the computers and accused the participants of hitting the "alt" key to see if they would sign a statement falsely taking responsibility.Redlich\'s findings clearly demonstrate how easy it can be to get people to falsely confess: 59 percent of the young adults in the experiment immediately confessed. ______ Of the 15-to 16-year-olds, 72 percent signed confessions, as did 78 percent of the 12-to 13-year-olds."There\'s no question that young people are more at risk," says Saul Kassin, a psychology professorat Williams College, who has done similar studies with similar results, "But adults are highly vulnerable too."Both Kassin and Redlich note that the entire "interrogation" in their experiments consisted of a simple accusation-not hours of aggressive questioning-and still, most participants falsely confessed.Because of the stress of a police interrogation, they conclude, suspects can become convinced that falsely confessing is the easiest way out of a bad situation. "In some ways," says Kassin, "false confession becomes a rational decision."【单选题】
A.In her experiment, participants were seated at computers and told not to hit the "alt" key, because doing so would crash the systems.
B."In some ways," says Kassin, "false confession becomes a rational decision."
C."It\'s a little like somebody\'s working on them with a dental drill," says Franklin Zimring, a law professorat the University of California at Berkeley.
D."But adults are highly vulnerable too."
E.How could an innocent person admit to doing something he didn\'t do?
F.Redlich also found that the younger the participant, the more likely a false confession.

5、Genetically Modified FoodEuropean unionenvironmental officials have determined that two kinds of genetically modified corn could harm butterflies, affect food chains and disturb life in rivers and streams, and they have proposed a ban on the sale of the seeds, which are made by Dupont Pioneer, Dow Agrosciences and Syngenta. The preliminary decisions are circulating within the European Commission, which has the final say. Some officials there are skeptical of a ban that would upsetthe powerful biotechnology industry and could exacerbate tensions with important trading partners like the United States. The seeds are not available on the European market forcultivation.In the decisions, the environment commissioner, Stavros Dimas, contends that the genetically modified corn, ormaize could affect certain butterfly species, specifically the monarch, and other beneficial insects. Forinstance, research this year indicates that larvae of the monarch butterfly exposed to the genetically modified corn "behave differently than other larvae." In the decision concerning the corn seeds produced by Dow and Pioneer, Mr. Dimas calls "potential damage on the environment irreversible." In the decision on Syngenta\'s corn, he says that "the level of risk generated by the cultivation of this product forthe environment is unacceptable."A decision by the European unionto bar cultivation of the genetically modified crops would be the first of its kind in the trade bloc, and would intensify the continuing battle over genetically modified corn. Banning the applications forcorn crops also would mark a bold new step forEuropean environmental authorities, who are already aggressively pursuing regulations on emissions from cars and aircraft, setting it at odds with the United States and angering industries."These products have been grown in the U. S. and other countries foryears," said Stephen Norton, a spokesman forthe United States trade representative. "We are not aware of any other case when a product has been rejected after having been reviewed and determined safe by European food safety authorities," he said.Barbara Helfferich, a spokeswoman forMr. Dimas, declined to comment on the specifics of the procedure because commissioners had not yet made a final decision. But she said that the European unionwas within its rights to make decisions based on the "precautionary principle" even when scientists had found no definitive evidence proving products can cause harm. She said that the decisions by Mr. Dimas could go before the commission within a few weeks, but she said that no date had been set. In the decisions, Mr. Dimas cited recent research showing that consumption of genetically modified corn byproducts reduced growth and increased mortality of non-target stream insects and that these insects are important prey foraquatic and riparian predators and that this could have unexpected ecosystem-scale consequences."Although still preliminary, his decisions could drastically tilt the policy against future approvals of genetically modified crops," said Nathalie Moll, a spokeswoman forEuropabio, an industrygroupwith 80 members including Syngenta, Pioneer and Dow. Europabio says that the crops grown using the genetically modified corn are already imported into several European countries, including France and Germany, where they are used to feed animals like cows and chickens.Rob Gianfranceschi, spokesman at the United States mission to the European unionin Brussels, said it was too early to comment on a decision that had not yet been formalized. But he made clear that the United States remained frustrated with European policies on genetically modified crops.The word "tilt" (line 1, paragraph 6) most probably means ______.【单选题】
A.incline
B.affect
C.induce
D.evoke
正确答案:A
答案解析:猜词题。根据上下文含义,尽管他的决定还是初步的,但是却会极大地倾向于针对同意未来转基因作物的政策,对比四个选项,只有incline符合此意,故正确答案为A。
