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 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 in all shapes and sizes and make up everything you can see, touch orfeel. How a molecule behaves depends on _____ 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 (機械響應性聚合物) 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.【單選題】
A.why
B.how
C.what
D.where
正確答案:C
答案解析:本題難度不大,考查賓語從句引導詞what的用法,本題可以先看選項,得到信息提示,很明顯,答案是C。
2、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 ______ 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 tested 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.【單選題】
A.many
B.more
C.few
D.fewer
正確答案:D
答案解析:前句說到更多病人可以被治愈,根據(jù)推理,后句應該是“將感染傳遞給別人的傳染病人就會更少”,因為前后兩句實際上具有因果關系。這里必須用比較級fewer,因為few是表示“不多的,幾乎沒有的(=not many)”,而fewer則只是與以前比較“更少”,并沒有明確多少。
3、We have got to abide by the rules. 【單選題】
A.stick to
B.persist in
C.safeguard
D.apply
正確答案:A
答案解析:abideby和stick to同義,遵循;persist in:堅持;safeguard:保護;apply:應用、申請。
4、Singing Alarms Could Save the BlindIf you cannot see, you may not be able to find your way out of a burning building and that could be fatal. A company in Leeds could change all that with directional sound alarms capable of guiding you to the exit. Sound Alert, a company run by the University of Leeds, is installing the alarms in a residential home forblind people in Sommersetand a resource centre forthe blind in Columbia. The alarms produce a wide range of frequencies that enable the brain to determine where the ______ is coming from. Deborah Withington of Sound Alert says that the alarms use most of the frequencies that can be heard by humans. "It\'s a burst of white noise that people say sounds like static on the radio," she says. "Its life-saving potential is great."She conducted an experiment in which people were filmed by thermal-imaging cameras trying to find their way out of a large smoke-filled room. It took them nearly four minutes to find the doorwithout a sound alarm, but only 15 seconds with one. Withington studies how the brain processes sounds at the university. She says that the source of a wide band of frequencies can be pinpointed more easily than the source of a narrow band. Alarms basedon the same concept have already been installed on emergency vehicles. The alarms will also include rising orfalling frequencies to indicate whether people should go up ordown stairs. They were developed with the aid of a large grant from British Nuclear Fuels. 【單選題】
A.noise
B.sound
C.music
D.bell
正確答案:B
答案解析:句子前半句是說a wide range of frequencies,所以發(fā)出的應是sound,因此答案選B。
5、What Do Dreams Tell Us?Why do we dream? Do dreams have meanings? These are questions which have troubled man forthousands of years. The oldest surviving book on the interpretation of dreams is Egyptian and is nearly 4,000 years old. In ancient Greece, it was thought that people who were ill could be cured by telling their dreams. They would relate their dreams to their doctors who would tell them what they meant and then give them medicine to make them well. The ancient Chinese believed that if a pregnant woman dreamed of a bear, she would have a son, and if she dreamed of a snake, she would have a daughter. There are many stories about dreams foretelling (預言) the future.We certainly do not now believe that dreams foretell the future. Most scientists believe that dreams are based on events in our own life and on our feelings. The events are usually very recent, mostly within the last two days. Our emotions, on the other hand our wishes, hopes and fears may go back many years, even to early childhood.In a dream, events are altered. A dream may contain parts of many real-life events. Most importantly, something that cannot be shown directly may be shown indirectly. Forexample, you might dream of driving a large car. This could mean not that you want to have a larger car, but that you desire power, and maybe you want to control other people. Again, you may dream that you are an actorin a play. The play is about to start, but you have completely forgot your lines. This dream may seem strange because you are not interested in acting, and you never want to be in a play. But the dream may mean that you have some other problem that you feel is too difficult foryou to solve.Psychologists believe that dreams may be helpful to us. Indeed, people who have been allowed to sleep in experiments, but not allowed to dream, have become anxious and restless. and when they are later allowed to sleep as much as they like, they dream more than ever to make us forthe lost "dream time". Paragraph 1 ______.【單選題】
A.Structure and interpretation of a dream
B.Ancient views on dreams
C.Babies dream less than older children
D.Dreaming may be good forour health
E.Dreams can not foretell the future
F.Healthy people do not dream
正確答案:B
答案解析:第一段主題句為第三句:These are questions which have troubled man forthousands of years. 這些問題已經(jīng)困擾了人類幾千年。段中則分別提到了古代埃及、希臘和中國對夢的理解。而B選項Ancient views on dreams(古人對夢的觀點)與其意思一致,故B為正確答案。
6、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.About the decisions, which one of the following statements is TRUE?【單選題】
A.The decisions aims to put a ban the sale of the seeds of genetically modified corn due to political and biological concerns.
B.The decisions are warmly embraced by all EU members but bitterly rejected by their trade partners.
C.The decisions could probably be made even if no definitive evidence proving the products harmful is found.
D.there is high possibility that the decisions would be approved by the European Commission.
正確答案:C
答案解析:細節(jié)考查題。答案參見第五段,Dimas先生的發(fā)言人指出,即使沒有確鑿證據(jù),歐洲委員會可以基于“預防原則”做出決定,故正確答案為C。
7、There is no risk to public health. 【單選題】
A.point
B.danger
C.chance
D.hope
正確答案:B
答案解析:risk和danger同義,危險的;point:某一想法;chance:機會;hope:希望。

A.feature
B.quality
C.diagram
D.source
正確答案:D
答案解析:解題關鍵是要看出句子中主要結構是more. . . than,后面出現(xiàn)核心詞the source,所以可以得出結論,前面的名詞也應是source,這樣符合比較級用法,用來進行比較的事物必須具有可比性,所以選D。
10、Cell Phones1. Believe it ornot, cell phones have been around forover a quarter of a century. The first commercial cell phone system was developed by the Japanese in 1979, but cell phones have changed a lot since that time. The early cell phones were big and heavy but they have developed into small and light palm sized models. There are huge developments in their functions, too. We have had call forwarding, text messaging, answering services and hands - free use foryears, but now there are new facilities, such as instant access to the Internet and receiving and sending photos.2. Cell phones have become very common in our lives. Recent statistics suggest one in three people on the planet now have cell phone, and most of them say they couldn\'t live without one, Cell phones are used in every area of our lives and have become a necessary tool, used foressential arrangements, social contact and business. It easier to call forhelp on the highway. It possible to keep in touch with people "on the move" when people are traveling.3. Cell phones have made communication easier and have reduced the need forfamily arguments f We can use cell phones to let our family know we\'ll be late orif there\'s a sudden change of plan oran emergency. Cell phones have eased the worries of millions of parents when their teenagers are out late. They can now contact their children at any time.4. This does not mean that cell phones are all good news. Cell phones have brought with them a number of new headaches fortheir owners. It costs a lot to replace stolen phones, It is becoming a frequent occurrence, and have you ever seen such a huge phone bills? More serious, however, Cell phones bring the potential health problem. There are fears that radiation from the phones may cause brain tumor腫瘤). This may be a time bomb waiting to happen to younger people who have grown up with cell phones. They simply can\'t live without cell phones!Cell phones are common in our lives and have become ______.【單選題】
A.a necessity
B.an emergency
C.a number of new headaches
D.family arguments
E.big and light palm - sized models
