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 effective 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 ______ 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】
A.increases
B.reductions
C.creations
D.collections
正确答案:B
答案解析:上面两句说到“可以防止大约20%的新病例和可能防止大约20%的死亡”,这自然是“降低”,而绝不可能是“增加”,更不是“创作品”、“收藏品”。
2、Science Fiction1 Amongst the most popular books being written today are those that are usually classified asscience fiction. Hundreds of titles are published every year and are read by all kinds of people. Furthermore, some of the most successful films of recent years have been based on science fiction stories. 2 It is often thought that science fiction is a fairly new development in literature, but its ancestors can be found in books written hundreds of years ago. These books were often concerned with the presentation of some forms of ideal society, a theme that is still often found in modern stories. 3 Most of the classics of science fiction, however, have been written within the last hundred years. Books by writers such as Jules Verve and H. G Wells, to mention just two well known authors, have been translated into many languages. 4 Modern science fiction writers don\'t write about men from Mars or space adventure stories. They are more interested in predicting the results of technical developments on society and the human mind; or in imagining future worlds that are a reflection of the world that we live in now. Because of this their writing has obvious political undertones (涵义). 5 In an age where science fact frequently overtakes (超过) science fiction, the writers may find it difficult to keep ahead of scientific advances. Those who are sufficiently clear-sighted to see the way we are going, however, may provide a valuable lesson on how to deal with the problems which society will inevitably face as it tries to master its new technology. Works of modern science fiction have____. 【单选题】
A.concerned with the problems that we will have to solve in the future
B.reading books of science fiction
C.political implication
D.a recurrent theme
E.read worldwide
F.translated into many languages
正确答案:C
答案解析:本题答案的依据在第4段最后一句,该句说Because of this their writing has obvious political undertones(由于这一原因,他们的作品带有明显的政治涵义)。实际上,undertone与implication的意思相同,故选C。
3、The town is famous for its magnificent buildings.【单选题】
A.high - rise
B.modern
C.ancient
D.splendid
正确答案:D
答案解析:这座小镇以华丽的建筑而出名。本题难度不大,干扰项干扰不强。magnificent和splendid都可指“华丽的”,是同义词,A项意为“高层的”,最佳答案是D。
4、The Threat to KiribatiThe people of Kiribati are afraid that one day in the not-too-distant future, their country will disappear from the face of the earth-literally. Several times this year, the Pacific island nation has been flooded by a sudden high tide. These tides, which swept across the island and destroyed houses, came when there was neither wind nor rain. "This never happened before," say the older citizens of Kiribati.What is causing these mysterious high tides? The answer may well be global warming. When fuels like oil and coal are being burned, pollutants (污染物) are released. These pollutants trap heat in the earth\'s atmosphere. Warmer temperatures cause water to expand and also create more water by melting glaciers (冰川) and polar (极地的) ice caps.If the trend continues, scientists say, many countries will suffer, Bangladesh, for example, might lose one-fifth of its land. The coral (珊瑚) island nations of the Pacific, like Kiribati and the Marshall Islands, however, would face an even worse fate-they would be swallowed by the sea. The loss of these coral islands would be everyone\'s loss. Coral formations are home to more species than any other place on earth.The people of these nations feel frustrated. The sea, on which their economies have always been based, is suddenly threatening their existence. They don\'t have the money for expensive technological solutions like seawalls. And they have no control over the pollutants, which are being released mainly by activities in large industrialized countries. All they can do is to hope that industrialized countries will take steps to reduce pollution.The people of the coral island nations are unable to do anything substantial about the problem of global warming.【单选题】
A.Right
B.Wrong
C.Not mentioned
正确答案:C
答案解析:题干大意:珊瑚岛国家的人对全球变暖问题无能为力。文章没有提到任何有关珊瑚岛国家的人的看法,故答案选C。
5、We\'ve seen a marked shift in our approach to the social issues.【单选题】
A.clear
B.regular
C.quick
D.great
正确答案:A
答案解析:我们已经看到在对待社会问题上我们态度的显著变化。本题难度很大,考生要重点研究。本题考查引申意义。marked的引申意义指“显著的”,和clear的引申意思“显著的”是同义词,D项great“极大的”干扰较大,有考生选择D,但最佳答案是A。
