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 ______ 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 a lot of work to do before the colorswitching molecules can be used outside the lab. 【单选题】
A.for
B.in
C.from
D.at
正确答案:D
答案解析:come at shapes and sizes,习惯用法。
2、Strike in MTV NetworksScores of workers from MTV Networks walked off the job yesterday afternoon, filling the sidewalk outside the headquarters of its corporate parent, Viacom, to protest recent changes in benefits. The walkout highlighted the concerns of a category of workers who are sometimes called permalancers: permanent freelancers who work like full-time employees but do not receive the same benefits.Waving signs that read "Shame on Viacom", the workers, most of them in their 20s, demanded that MTV Networks reverse a plan to reduce health and dental benefits forfreelancers beginning Jan. 1. In a statement, MTV Networks noted that its benefits program forfull-time employees had also undergone changes, and it emphasized that the plan forfreelancers was still highly competitive within the industry. Many freelancers receive no corporate benefits. But some of the protesters asserted that corporations were competing to see which could provide the most mediocre health care coverage. Matthew Yonda, who works at Nickelodeon, held a sign that labeled the network "Sick-elodeon". "I\'ve worked here every day forthree years-I\'m not a freelancer," Mr. Yonda said. "They just call us freelancers in orcerto bar us from getting the same benefits as employees."The changes to the benefits package were announced last Tuesday. Freelancers were told that they would become eligible forbenefits after 160 days of work, beginning in January. While that eased previous eligibility rules, which required freelancers to work for52 weeks before becoming eligible, it would have required all freelancers not yet eligible forbenefits to start the waiting period over again on Jan. 1. The 401 (k) plan was also removed On Thursday, acknowledging the complaints, MTV Networks reinstated the 401 (k) plan and said freelancers who had worked consistently since March would be eligible.Fueled by a series of blog posts on the media web site Gawker-the first post was headlined "The Viacom Permalance Slave System" -a loose cohort of freelancers created protest stickers and distributed walkout fliers last week. Caroline O\'Hare, a unit manager who has worked forMTV formore than two years, said the new health care plan-with higher deductibles and a $ 2,000 cap on hospital expenses each year-had provoked outrage. "They think they can treat us like children that don\'t have families, mortgages ordreams of retirement," she said.Outside Viacom\'s headquarters, several workers held posters with the words, "There\'s too many of us to ignore." It was unclear how many freelancers are on the company\'s payroll; an MTV Networks spokeswoman said the figure was not known because it rises and falls throughout the year. The company has 5,500 full-time employees, excluding freelancers, around the world.Two freelancers and one full-time employee, who asked not to be identified forfear of retribution, estimated that the percentage of freelancers in some departments exceeded 75 percent. Another laboraction is expected to take place outside Viacom later this week. Members of the Writers Guild of America, who have been on strike forfive weeks, are expected to picket there on Thursday.According to the new benefits program of MTV Networks, the following freelancers are eligible forbenefits except ______.【单选题】
A.those who have worked for160 days
B.those who have worked for1 year
C.those who have worked since March
D.those who have worked since Jan. 1

5、The SmogForover a month, Indonesia was in crisis. Forest fires raged out of control as the country suffered its worst drought for50 years. Smoke from the fires mixed with sunlight and hot dry air to form a cloud of smog. This pollution quickly spread and within days it was hanging over neighboring countries including Malaysia, Singapore and Thailand. When the smoke combined with pollution from factories and cars, it soon became poisonous. Dangerous amounts of CO became trapped under the smog and pollution levels rose. People wheezed (喘息) and coughed as they left the house and their eyes watered immediately. The smog made it impossible to see across streets and whole cities disappeared as grey soot(烟灰) covered everything. In some areas, water was hosed (用胶管浇) from high-rise city buildings to try and break up the smog. Finally, heavy rains, which came in November. Put out the fires and clear the air. But the environmental costs and health problems will remain. Many people from South-Eastern Asian cities already suffer from breathing huge amounts of car exhaust fumes and factory pollution Breathing problems could well increase and many non-sufferers may have difficulties forthe first time. Wildlife has suffered too. In lowland forests, elephants, deer, and tigers have been driven out of their homes by smog. But smog is not just an Asian problem. In fact. was world was first used in London in 1905 to describe the mixture of smoke and thick fog. Fog often hung over the capital. Sometimes the smog was so thick and poisonous that people were killed by breathing problems orin accidents. About 4, 000 Londoners died within five days as a result of thick smog in 1952. The word "smog" first appeared in 1952. 【单选题】
A.Right
B.Wrong
C.Not mentioned
正确答案:B
答案解析:题句的意思是smog这个词最早出现于1952年。最后一段提到这个词是在1905年首次出现的。题句意思与原文不符,故选B。

7、Arctic MeltEarth\'s North and South Poles are famous forbeing cold and icy. Last year, however, the amount of ice in the Arctic Ocean (北冰群) fell to a record low.Normally, ice builds in Arctic waters around the North Pole each winter and shrinks(缩小) during the summer. But formany years, the amount of ice left by the end of summer has been declining.Since 1979, each decade has seen an 11.4 percent drepin end of summer ice cover. Between 1981 and 2000, ice in the Arctic lost 22 percent of its thickness, becoming 1.13 meters thinner.Last summer, Arctic sea ice reached its thinnest levels. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. That\'s 38 percent less area than the average cover at that time of year. and it\'s a very large 23 percent below the previous record low, which was setjust 2 years ago. This continuing trend has made scientists concerned to.There may be several reasons forthe ice melt, says Jinlun Zhang, an oceanographer (海洋学家)at the University of Washington in Seattle. Unusually strong winds blew through the Arctic last summer. The winds pushed much of the ice out of the central Arctic, leaving a large area of thin ice and open water.Scientists also suspect that fewer clouds cover the Arctic now than in the past. Clearer skies allow more sunlight to reach the ocean. The extra heat warms both the water and the atmosphere. In parts of the Arctic Ocean last year, surface temperatures were 3.57 Celsius warmer than the average and 1.5c warmer than the previous record.With both air and water getting warmer, the ice is melting from both above and below. In some parts of the Beaufort Sea, north of Alaska and western Canada, ice that measured 3.3 meters thick at the beginning of the summer was measured just 50 cm by season\'s endThe new measurements suggest that melting is far more severe than the thinking of scientists. Some scientists fear that the Arctic is stuck in a warming trend.It can be learned from the last sentence that ______.【单选题】
A.the ice melt in the Arctic may never stop
B.scientists are trying hard to stop the ice melt in the Arctic
C.scientists are delighted to find out what is going on in the Arctic
D.the warming trend in the Arctic can be reversed in the near future

9、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。
10、Better Control of TB Seen if a Faster Cure is FoundThe World Health Organization estimates that about one-third of all people are infected with bacteria that cause tuberculosis. Most times, the infection remains inactive. But each year about eight million people develop active cases of TB, usually in their lungs. Two million people die of it. The disease has increased with the spread of AIDS and drug-resistant forms of tuberculosis. Current treatments take at least six months. Patients have to take a combination of several antibiotic drugs daily. But many people stop as soon as they feel better. Doing that can lead to an infection that resists treatment. Public health experts agree that a faster-acting cure fortuberculosis would be more effective. Now a study estimates just how effective it might be. A professorof international health at Harvard University led the study. Joshua Salomon says a shorter treatment program would likely mean not just more patients cured. It would also mean fewer infectious patients who can pass on their infection to others. The researchers developed a mathematical model to examine the effects of a two-month treatment plan. They ______ the model with current TB conditions in Southeast Asia. The scientists found that a two-month treatment could prevent about twenty percent of new cases. and it might prevent about twenty-five percent of TB deaths. The model shows that these reductions would take place between two thousand twelve and two thousand thirty. That is, if a faster cure is developed and in wide use by two thousand twelve. The World Health Organization developed the DOTS program in nineteen ninety. DOTS is Directly Observed Treatment, Short-course. Health workers watch tuberculosis patients take their daily pills to make sure they continue treatment. Earlier this year, an international partnership of organizations announced a plan to expand the DOTS program. The ten-year plan also aims to finance research into new TB drugs. The four most common drugs used now are more than forty years old. The Global Alliance forTB Drug Development says its long-term goal is a treatment that could work in as few as ten doses.【单选题】
A.provided
B.introduced
C.tested
D.tempted
正确答案:C
答案解析:只有填C(检验)才能符合上下文意思,其他3项不仅词义不合适,词的用法也不对。
