1、Inventｏｒof LEDWhen Nick Holonyak ｓｅｔout to create a new kind of visible lighting using semiconductｏｒalloys, his colleagues thought he was unrealistic. Today, his discovery of light-emitting diodes, ｏｒLEDs, are used in everything from DVDs to alarm clocks to airports. Dozens of his students have continued his work, developing lighting used in traffic lights ａｎｄ　other everyday technology. On April 23,2004, Holonyak received the $500,000 Lemelson-MIT Prize at a ceremony in Washington. This marks the lOth year that the Lemelson-MIT Program at the Massachusetts Institute of Technology (MIT) has given the award to prominent inventors. "Anytime you get an award big ｏｒlittle. It\'s always a surprise. " Holonyrak said. Holonyak, 75, was a student of john Bardeen, an inventｏｒof the transistor, in the early 1950s. After graduate school, Holonyak worked at Ben Labs. He later went to General Electric, where he invented a switch now widely used in house dimmer switches. Later, Holonyak started looking into how semiconductors could be used to generate light. But while his colleagues were looking at how to generate invisible light, he wanted to generate visible light. The LEDS he invented in 1962 now last about 10 times longer than incandescent bulbs, ａｎｄ　are more environmentally friendly ａｎｄ　effective. Holonyak, now a professｏｒof electrical ａｎｄ　computer engineering ａｎｄ　physics at the University of Illinois, said he suspected that LEDs would become as commonplace as they are today, but didn\'t realize how many uses they would have. "You don\'t know in the beginning. You think you\'re doing something important. You think it\'s worth doing, but you really can\'t tell what the big payoff is going to be, ａｎｄ　when, ａｎｄ　how. You just don\'t know, "he said. The Lemelson. MIT Program also recognized Edith Flanigen, 75, with the $100,000 Lemelson-MIT Lifetime Achievement Award fｏｒher work on a new generation of "molecular sieves", that can separate molecules by size. Holonyak said that you should not do anything you are not interested in.【单选题】

2、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 nｏｒrain. "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, fｏｒexample, 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 fｏｒexpensive 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 Kiribati worry that one day their country will be taken away by a sudden high tide.【单选题】

C.Not mentioned

正确答案:B

答案解析:题干大意：科学家不确定全球变暖将产生多么严重的后果。文章第三段提到：If the trend continues, scientists say, many countries will suffer...would face an even worse fate. 如果按照这个趋势继续发展，很多国家将会遭受或者面临更严重的危机。也就是说科学家们还是看到了全球变暖的严峻性。故答案选B。

4、Lakes, Too, Feel Global WarmingThere\'s no doubt, In the last few decades, the average temperature on Earth has been higher than it has been in hundreds of years. Around the world, people are starting to measure the effects of global warming ａｎｄ　trying to figure out what to do about it.Scientist recently used satellites to study the temperatures of lakes around the world ａｎｄ　they found that lakes are heating up. Between 1985 ａｎｄ　2009, satellites recorded the night time temperatures of the surfaces of 167 lakes. During those 24 years, the lakes got warmer by an average of about 0.045 degree Celsius per year.In some places, lakes have been warming by as much as 0.10 degree Celsius per year. At that rate, a lake may warm by a full degree Celsius in just 10 years. That difference may seem small you might not even notice it in your bath. But in a lake, slightly warmer temperatures could mean more algae (水藻) ａｎｄ　algae can make the lake poisonous to fish.The study shows that in some regions, lakes are warming faster than the air around them. This is important because scientists often use measurements of air temperature to study how Earth is warming. By using lake temperatures as well, scientists can get a better picture of global warming. The scientists say data on lakes give scientists a new way to measure the impact of climate change around the world.That\'s going to be useful, since no matter the country is too big ｏｒtoo small can\'t ignore climate changes. Scientists aren\'t the only ones concerned. Everyone who lives on Earth is going to be affected by the rapid warming of the planet. Many world leaders believe we might be able to do something about it, especially by reducing the amount of greenhouse(温室) gases we put into the air.That\'s why the United Nations started the Framework Convention on Climate Change, ｏｒUNFCCC. Every year the convention meets, ａｎｄ　representatives from countries around the world gather to talk about climate change ａｎｄ　discuss global solutions to the challenges of a warming world.The temperatures of lakes around the world have increased greatly between 1985 - 2009.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:本题难度不大，答案依据比较明显，在文章第二段第三句：During those 24 years, the lakes got warmer-by an average of about 0.045 degree Celsius per year.很明显，每年湖水的温度平均才上升0. 045度，题干却说have increased greatly，和原文句意明显不符，答案是B。

5、A Great Quake Coming?Everyone lives in San Francisco knows that earthquakes are common in the Bay Area ａｎｄ　they can devastate. In 1906, fｏｒexample, a majｏｒquake destroyed about 28000 buildings ａｎｄ　killed hundreds, perhaps thousands of people. Residents now wonder when will the next "Big One" strike. It\'s bound to happen someday. At least seven active fault(断层) lines run through the San Francisco area. Faults are places where pieces of Earth\'s crust (地壳) slide past each other. When these pieces slip, the ground shakes.To prepare fｏｒthat day, scientists are using new techniques to reanalyze the 1906 earthquake ａｎｄ　predict how bad the damage might be when the next one happens.One new finding about the 1906 quake is that the San Andreas Fault split apart faster than scientists had assumed at the time. During small earthquakes, faults rupture(断裂) about 2.7 kilometers persecond. During bigger quakes, however, ruptures can happen faster than 3.5 kilometers persecond.At such high speeds, massive amounts of pressure build up, generating underground waves that can cause more damage than the quake itself. Lucky fｏｒSan Francisco, these pressure pulses (脉冲) traveled away from the city during the 1906 event.Looking ahead, scientists are trying to predict when the next majｏｒquake will occur. Records show that earthquakes were common before 1906. Since then, the area has been relatively quiet. Patterns in the data, however, suggest that the probability of a majｏｒearthquake striking the Bay Area before 2032 is at least 62 percent.New buildings in San Francisco are quite safe in case of future quakes. Still, more than 84 percent of the city\'s buildings are old ａｎｄ　weak. Analyses suggest that another massive earthquake would cause extensive damage.People who live there today tend to feel safe because San Francisco has remained pretty quiet fｏｒa while. According to the new research, however, it\'s not a matter that whether "the Big One" will hit here. It\'s just a matter of when.A majｏｒearthquake striking San Francisco someday is inevitable.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:本题有一定难度，需要认真吃透句意，做好判断。答案依据在第五段。第五段最后一句：the probability of a majｏｒearthquake striking the Bay Area before 2032 is at least 62 percent.谈到在2032年前海湾地区发生大地震的可能性至少是62%，说明概率很高，所以本题正确，答案是A。
