1、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 for tuberculosis would be more effective. Now a study estimates just how ______ it might be. A professor of 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 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 for TB Drug Development says its long-term goal is a treatment that could work in as few as ten doses.【单选题】

5、A Bad IdeaThink you can walk, drive, take phone calls, e - mail and listen to music at the same time 7 Well, New York\'s new law says you can\'t. And you\'ll be fined $ 100 if you do so on a New York city street. The law went into force last month, following research and a shocking number of accidents that involved people using electronic gadgets (小巧机械) when crossing the street.Who\'s to blame? Scientists say that our multitasking (多任务处理) abilities are limited. "We are under the impression that our brain can do more than it often can," says Rene Marois, a neuroscientist (神经科学家) in Tennessee. "But a core limitation is the inability to concentrate on two things at once."The young people are often considered the great multitaskers. However, an Oxford University research suggests this perception is open to question. A group of 18 to 21 years old and a group of 35 to 39 years old were given 90 seconds to translate images into numbers, using a simple code. The younger group did 10 percent better when not interrupted. But when both groups were interrupted by a phone call or an instant message, the older group matched the younger group in speed and accuracy.It is difficult to measure the productivity lost by multitaskers. Jonathan Spira, chief analyst at Basex, a business - research firm, estimates that the cost of interruptions to the American economy is nearly $ 650 billion a year. _____. The surveys conclude that 28 percent of the workers\' time was spent on interruptions and recovery time before they returned to their main tasks.【单选题】

A.Talking on a cell phone while driving brings you joy anyway.

B.The estimate is based on surveys with office workers.

C.The younger group did 10 percent better when not interrupted.

D.However, an Oxford University research suggests this perception is open to question.

E.Scientists say that our multitasking (多任务处理) abilities are limited.

F.And you\'ll be fined $ 100 if you do so on a New York city street.

正确答案:B

答案解析:本题有一定的难度，需要认真阅读文章，理解好句意。可用排除法和代入法。本题的下文谈到了对（办公室）职工做的一次调查，涉及具体内容，所以可以推断此处应该是概括性的句子，来引导下文，而且和职工调查有关，回来看选项，把B代入文中，符合逻辑，答案是B。

6、Seeing Red Means Danger AheadThe color red often means danger and by paying attention, accidents can be prevented. In the future, the color red also may help prevent danger at construction sites. Thanks to new work by engineers, bridge supports or other kinds of materials could one day contain a color switching material. It will turn red before a structure collapses or falls apart. The secret behind the color switching material is a particular type of molecule. A molecule is a group of atoms held together by chemical bonds. Molecules come at all shapes and sizes, and make up everything. You can see, touch or feel. 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 switching 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" or weak, 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 switching polymers in their lab. The test results proved encouraging. There is a way to get rid of the color light when a bright light is shone on the mechanophore. The broken bond is fixed and the red color ______. This "self-healing" may be a problem for engineers. They need to use the color changer 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 color switching molecules can be used outside the lab. 【单选题】

A.repairs

B.controls

C.finishes

D.disappears

正确答案:D

答案解析:前文说断裂的联系从新凝合，那么红色相对应的，就应是消失、褪去。

7、The SmogFor over a month, Indonesia was in crisis. Forest fires raged out of control as the country suffered its worst drought for 50 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 for the 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 or in accidents. About 4, 000 Londoners died within five days as a result of thick smog in 1952. Many Indonesians blamed the government for the drought. 【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:C

答案解析:题句意思是“很多印尼人因为旱灾而抱怨政府”。这层意思文中根本没有提到，故选C。

8、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, or black 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 for more than a night or two. Then they move on to look for more 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. Among the three kinds of apes, ____【单选题】

A.the gorilla is the biggest

B.the gibbon is only three feet high but it is heavier than the orangutan

C.the orangutan is smaller than the gorilla and cleverer than the gibbon

D.the orangutan can stand up to a great height, but others cannot

正确答案:A

答案解析:文章第5段指出，长臂猿(gibbon)高不足3英尺，重仅14磅；大猩猩(gorilla)高6英尺，重达600磅；猩猩( orangutan)高3至5英尺，重200磅。综合可知A正确。

9、You have to be patient if you want to sustain your position.【单选题】

A.maintain

B.establish

C.acquire

D.support

正确答案:A

答案解析:题干大意：如果你想保住位子就得有耐心。画线词sustain：维持，可以用maintain来替代。establish：建立，创办。acquire：获得，取得。support：支持。故答案选A。

10、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 professor at 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. Redlich also found that the younger the participant, the more likely a false confession. 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 professor at 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. ______【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 professor at 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.

正确答案:B

答案解析:由于审讯室的巨大压力，嫌疑人很可能为了逃离那种环境而承认自己本没有做过的事。因此，Kassin说，从某种程度上看，错误的妥协在那种情况下是一种理性的选择。
