1、One Good Reason to Let Smallpox LiveIt\'s now a fair bet that we will never see the total extinction (灭绝) of the smallpox (天花) virus. When smallpox was completely got rid of in the world, scientists wanted to destroy the killer virus in the last two labs, one in the US and one in Russia. They asked: If smallpox has truly gone from the planet, what point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let go of such a powerful potential weapon. Undoubtedly several nations still have a few vials (小药瓶). and the last "official" stocks of live Virus bred mistrust of the US and Russia, forno obvious gain.Now American researchers have found an animal model of the human disease, opening the way fortests on new treatments and vaccines(疫苗). So once again there\'s a good reason to the virus, just in _____ the disease puts in a reappearance.How do we case with the mistrust of the US and Russia? deal. Keep the virus Simple international support in a well - guarded UN laboratory that\'s open to all countries. The US will object, of course, just as it with a multilateral (多边的) approach to just about everything. But it doesn\'t mean the idea is rejects. If the virus is useful, then let\'s wrong it the servant of all humanity make not just a part of it.【单选题】

2、Weaving with LightIn the Sierra Madre mountain range of west central Mexico, the native Huichol people live much the way their ancestors did-without electricity. That\'s because it\'s too expensive to string power lines to the remote mountain areas where they live. To help support themselves, the Huichol create beautiful artwork. They sell their art in cities hundreds of miles away from their villages. and without electricity, at home oron the road, they can only work during daylight hours. When it gets dark, they must stop whatever they\'re doing.Now, a team of scientists, designers and architects is using new technologies to provide the Huichol with light after the sun sets. The scientists technique involves weaving tiny electronic crystals into fabrics that can be made into clothes, bags, orother items.By collecting the sun\'s energy during the day, these lightweight fabrics provide bright white light at night. Their inventors have named the fabrics "Portable Lights," Portable Lights have the potential to transform the lives of people without electricity around the world, says project leader Sheila Kennedy."Our invention," Kennedy says, "came from seeing how we could transform technology we saw every day in the United States and move it into new markets forpeople who didn\'t have a lot of money."At the core of Portable Light technology are devices called high - brightness light - emitting diodes, orHB LEDs. These tiny lights appear in digital clocks, televisions and streetlights.LEDs are completely different from the light bulbs. Most of those glass bulbs belong to a type called incandescent lights. Inside, electricity heats a metal coil to about 2,200 degrees Celsius. At that temperature, bulbs give off light we can see.Ninety percent of energy produced by incandescent lights, however, is heat and invisible. With all that wasted energy, bulbs burn out quickly. They are also easily broken.LEDs, on the other hand, are like tiny pieces of rock made up of molecules that are arranged in a crystal structure. When an electric current passes through an LED, the crystal structure produces light. Unlike incandescent bulbs, they can produce light of various colors. Within an LED, the type of molecules and their particular arrangement determines what coloris produced.All of the following are disadvantages of incandescent lights EXCEPT that ______.【单选题】
A.they are not bright enough
B.they burn out quickly
C.they are easily broken
D.they waste most of the energy produced
正确答案:A
答案解析:本题难度较大,需要通读全文,寻找答案依据。通读全文可以发现,只有they are not bright enough是文章未提到的,答案是A。
3、Light Night, Dark StarsThousands of people around the globe step outside to gaze at their night sky. On a clear night, with no clouds, moonlight, orartificial lights to block the view, people can see more than 14,000 stars in the sky, says Dennis Ward, an astronomer(天文学家) with the University Corporation forAtmospheric Research( UCAR) in Boulder, Colo. But when people are surrounded by city lights, he says, they\'re lucky to see 150 stars.If you\'ve ever driven toward a big city at night and seen its glow from a great distance, you\'ve witnessed light pollution. It occurs when light from streetlights, office buildings, signs, and other sources streams into space and illuminates (照亮) the night sky. This haze (朦胧) of light makes many stars invisible to people on Earth. Even at night, big cities like New York glow from light pollution, making stargazing difficult.Dust and particles of pollution factories and industries worsen the effects of light pollution. "If one city has a lot more light pollution than another," Ward says, "that city will suffer the effects of light pollution on a much greater scale."Hazy skies also make it far more difficult forastronomers to do their jobs.Cities are getting larger. Suburbs are growing in once dark, rural areas. Light from all this new development is increasingly obscuring (使变模糊) the faint (微弱的) light give off by distant stars. and if scientists can\'t locate these objects, they can\'t learn more about them.Light pollution doesn\'t only affect star visibility. It can harm wild life too. It\'s clear that artificial light can attract animals, making them go off course. There\'s increasing evidence, forexample, that migrating (迁徙) birds use sunsets and sunrises to help find their way, says Sydney Gauthreaux Jr. , a scientist at Clemson University in South Carolina, "When light occurs at night," he says, "it has a very disruptive (破坏性的) influence." Sometimes birds fly into lighted towers, high - rises, and cables from radio and television towers. Experts estimate that millions of birds die this way every year.Nowadays even suburbs are becoming unsuitable forscientists to do their jobs because ______.【单选题】
A.the night sky there is too dark
B.the once dark areas are also polluted by lights
C.these areas are not polluted by chemicals
D.these areas are less developed
正确答案:B
答案解析:本题有一定难度,需要认真第五段,吃透句意。文章第五段谈到,市郊的灯火使科学家无法观测到天空星体发出微弱光线,回来看选项,B项符合原文句意,是答案。
4、Black HolesMost scientists agree that black holes exist but are nearly impossible to locate. A black hole in the universe is not a solid object, like a planet, but it is shaped like a sphere (球体). Astronomers (天文学家) think that at the center of a black hole there is a single point in space with infinite (无限的) density (稠密).This single point is called a singularity (奇点). If the singularity theory is correct, it means that when a massive star collapses, all the material in it disappears into the singularity. The center of a black hole would not really be a hole at all, but an infinitely dense point. Anything that crosses the black hole is pulled in by its great gravity.Although black holes do exist, they are difficult to observe. These are the reasons,?No light oranything else comes out of black holes. As a result, they are invisible to a telescope.?In astronomical terms, black holes are truly. Forexample, a black hole formed by the collapse of a giant star would have an event horizon (视界) only 18 miles across.?The nearest black holes would be dozens of light years away from Earth. One light year is about 6 trillion (万亿) miles. Even the most powerful telescopes could not pick out an object so small at such a great distance.In 1994 the Hubble Space Telescope provided evidence that black holes exist. There are still answers to be found, however, so black holes remain one of the mysteries of the universe. (2007年)Black holes exist but are difficult to observe.【单选题】
A.Right
B.Wrong
C.Not mentioned
正确答案:A
答案解析:题干大意:黑洞是存在的,但是很难观察到。题干中的关键词为difficult,用它回到原文定位,在首句能找到difficult的近义词impossible。文章首句提到:Most scientists agree that black holes exist but are nearly impossible to locate. 黑洞确实存在,但很难定位(locate),与题意信息相符,故答案选A。

6、The Value of AdvertisementMoney spent on advertising is worth spending. It serves directly to bring about a rapid sale of goods at reasonable prices, so setting up a firm home market and making it possible to provide forexport at good price. By drawing attention to new ideas it helps greatly to raise standards of living. By helping to increase demand it causes an increased need forlabor, and is therefore a nice way to fight unemployment. It lowers the costs of many services: without advertisements your daily newspaper would cost four times as much, the price of your television program would need to be doubled, and travel by bus orsubway would cost more. and perhaps most important of all, advertising provides a promise of reasonable value in the products and services you buy. Besides the fact that twenty-seven Acts of Parliament govern the terms of advertising, no regular advertiser dare produce anything that fails to live up to the promise of his advertisements. He might fool some people fora little while through misleading advertising. He will not do so forlong, forthe public has the good sense not to buy the poorgoods more than once. If you see a product frequently advertised, it is the proof I know that the product does what is promised forit, and that it has good value. Advertising does more forthe good of the public than any other force I can think of. There is one more point I feel I ought to touch on. Recently I heard a well-known television person declare that he was against advertising because it persuades rather than informs. He was telling us the real difference. Of course advertising tries to persuade. If its messages were nothing but information, that would be difficult to get more people to buy, foreven the choice of the colorof a shirt is a bit persuasive-advertising would be so boring that no one would pay any attention. But perhaps that is what the well-known television person wants.Which of the following is the most important advantage according to the passage?【单选题】
A.Reducing the cost of your daily newspaper.
B.Lowering the price of your television program.
C.Making it possible to provide forexport at good price.
D.Providing a promise of reasonable value in the products and services you buy.
正确答案:D
答案解析:选项A、B、C、D都是提到的好处,但是从文章第2段第1句可知,最重要的是广告能提供产品和服务的价值承诺。因此选D。

8、The Hurricane1. A hurricane (飓风) is a tropical storm with winds that have reached a constant speed of 74 miles per hour. Hurricane winds blow in a large spiral(螺旋) around a relative calm center known as the "eye". The "eye" is generally 20 to 30 miles wide, and the storm may extend outward 400 miles. As a hurricane nears land, it can bring heavy rains, high winds and storm surges(风暴潮). The storm surges and heavy rains can lead to flooding.2. Hurricanes are given a different label, depending on where they occur. If they begin over the North Atlantic Ocean, the Caribbean Sea, The Gulf of Mexico, orthe Northeast Pacific Ocean, they are called hurricanes. Similar storms that occur in the Northwest Pacific Ocean west of the Internaional Date Line are called typhoons near Australia and in the Indian Ocean, they are referred to as tropical cyclones(龙卷风).3. When a hurricane hits land, it can do great damage through its fierce winds, heavy rains, inland(内陆的) flooding and huge waves crashing on to the shore. During a hurricane, homes, businesses and public buildings may be damaged ordestroyed, roads and bridges can be washed away. A powerful hurricane can kill more people and destroy more property than any other natural disaster. Fishermen are at special risk from hurricanes as they may be at sea when a hurricane arrives and not be able to get to a safe harborif they do not receive adequate warning.4. If a hurricane is comming in your area, the most important thing is to stay calm and find shelter immediately. Go to your safe room. If you do not have one, stay indoors during the hurricane and go to a safer place near the center of your home. Cover yourself with a blanket and be sure to keep away from windows and glass doors, because if the glass breaks it’s really dangerous. Do not be fooled if there is lull(暂停), it could be the eye of the storm—winds will pick up again.Paragraph 4 ______【单选题】
A.Where do hurricanes usually happen?
B.What damages can a hurricane cause?
C.What should you do during a hurricane?
D.What is a hurricane?
E.What are different names of hurricanes?
F.How do you know a hurricane is coming?
正确答案:C
答案解析:本题难度不大,段落主旨句比较明显,在文章第四段的第一句:If a hurricane is coming in your area, the most important thing is to stay calm and find shelter immediately.回来看选项,C项简单概括了第一段的主要意思,是答案。
9、An Intelligent CarDriving needs sharp eyes, keen ears, quick brain, and coordination between hands and the brain. Many human drivers have all. these and can control a fast-moving car. But how does an intelligent car control itself ?There is a virtual driver in the smart car. This virtual driver has "eyes," "brains", "hands" and "feet", too. The mini-cameras on each side of the car are his "eyes," which observe the road and conditions ahead of it. They watch the traffic to the car\'s left and right. There is also a highly automatic driving system in the car. It is the built-in computer, which is the virtual driver\'s "brain". His "brain" calculates the speeds of other moving cars near it and analyzes their positions. Basing on this information, it chooses the right line forthe intelligent cars, and gives instructions to the "hands" and "feets" to act accordingly. In this way, the virtual driver controls his car. What is the virtual driver\'s best advantage? He reacts rapidly. The mini-cameras are sending images continuously to the "brain". It completes the processing of the images within 100 milliseconds. However, the world\'s best driver at least needs one second to react. Besides, when he takes action, he needs one more second. The virtual driver is really wonderful. He can reduce the accident rate. considerably on expressway. In this case, can we let him have the wheel at any time and in any place? Experts warn that we cannot do that just yet. His ability to recognize things is still ______. He can now only drive an intelligent car on expressways. 【单选题】
A.unknown
B.few
C.untested
D.limited
正确答案:D
答案解析:空白所在的句子说“他识别不同东西的能力仍然还……”,空白后句说“他现在只能驾驶智能车在高速路上行驶”。既然能在高速路上行驶,则其应该具备一定识别物体的能力,而且应该已经经过检测,因此排除A(未知的)和C(未经试验的);few应该修饰可数名词的复数形式,而句子主语(被修饰词)是单数,因此排除B,答案是D(有限的)。
10、A special educationVideodisc holds great promise of helping to meet the needs of American schoolchildren who have problems seeing, hearing, speaking, orsocializing. Almost eleven percent of the students aged 3-21 in this country have an impairment that affects their ability to benefit from a regular education program. Handicapped students require special education because they are often markedly different from most children in one ormore of the following ways: mentally retarded (发展迟缓的) learning-disabled, emotionally disturbed, deaf, visually handicapped, physically handicapped, orother health impairments. The education of these handicapped children is rewarding but challenging. A special education student usually needs a longer period of time to acquire information. Repetitive teaching techniques are often beneficial, and indefatigable (孜孜不倦) consistency on the part of the teacher is frequently necessary. Interactive videodisc courseware has characteristics that can be capitalized upon to meet the challenges that special education poses. A videodisc program is infinitely patient. Repetition of any videodisc lesson can continue endlessly, and designers can assure absolute consistency within a program. Most important, according to special educatorWilliam Healey of the University of Arizona, is that videodisc "adds an extra dimension of realism forchildren who need graphic representations."Healey explained that deaf and mentally retarded children especially have difficulty grasping figurative language and higher-orcerlanguage concepts. He believes that forspecial education, the power of videodisc lies in the ability of the technology to visually represent language concepts normally taken forgranted by non-handicapped persons. Complex figurative language forms such as idioms and metaphors come most readily to mind as being difficult forhandicapped learners. The special education mentioned in the text is mainly concerned with____. 【单选题】
A.genius students from day-care centers to colleges
B.students who are fond of computer video games
C.teachers of language in the University of Arizona
D.students who are either mentally orphysically disabled
正确答案:D
答案解析:由文章第1段“Handicapped students require special education because they are. . . ”可知,文中提及的特殊教育针对的是有智力和身体残疾的学生们,故选D。
