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. Edith Flanigen is the only co-inventｏｒof LEDs.【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】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:题干大意：基里巴斯人民担心也许有一天他们的国家会被一个突然的高潮卷走。文章开头首句提到：The 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. 基里巴斯人民担心在不久的将来一天，他们的国家就会从地上消失。今年有几次，太平洋岛国已经遭到突然的高潮冲淹。题干所述与文章信息一致，故答案选A。

3、The great change of the city astonished all the visitors.【单选题】

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.Global warming is less threatening to small countries.【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，在文章第五段第一到第三句：That\'s going to be useful, since no country is too big ｏｒtoo small to 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. 谈到无论大国家还是小国家都要受到气候变暖的影响，题干却说 less threatening to small countries，和原文句意不符，答案是B。

5、Animal\'s "Sixth Sense"A tsunami was triggered by an earthquake in the Indian Ocean in December, 2004. It killed tens of thousands of people in Asia ａｎｄ　East Africa, Wild animals, however, seem to have escaped that terrible tsunami. This phenomenon adds weight to notions that they possess a "sixth sense" fｏｒdisasters, experts said.Sri Lankan Wildlife officials have said the giant waves that killed over 24,000 people along the Indian Ocean island\'s coast clearly missed wild beasts, with no dead animals found."No elephants are dead, not even a dead rabbit. I think animals can sense disaster. They have a sixth sense. They know when things are happening" H. D. Ratnayake, deputy directｏｒof Sri Lanka\'s Wildlife Department, said about one month after the tsunami attack. The waves washed floodwaters up to 2 miles inlａｎｄ　at Yala National Park in the ravaged southeast, Sri Lanka\'s biggest wildlife reserve ａｎｄ　home to hundreds of wild elephants ａｎｄ　several leopards."There has been a lot of scientific evidence about dogs barking ｏｒbirds migrating before volcanic eruptions ｏｒearthquakes. But it has not been proven," said Matthew van Lierop, an animal behaviｏｒassistant at Johannesburg Zoo. "There have been no specialist studies because you can\'t really test it in a lab ｏｒfield setting," he told Reuters. Other authorities concurred with this ______."Wildlife seem to be able to pick up certain phenmenon, especially birds. There are many reports of birds detecting impending disasters," said Clive Walker, who has written several books on African wildlife.Animals certainly rely on the known senses such as smell ｏｒhearing to avoid danger such as predators. The notion of an animal "sixth sense" -ｏｒsome other mythical power-is an enduring one which the evidence on Sri Lanka\'s ravaged coast is likely to add to. The Romans saw owls as omens of impending disaster ａｎｄ　many ancient cultures viewed elephants as sacred animals endowed with special powers ｏｒattributes.【单选题】

A.modification

B.detection

C.assessment

D.value

正确答案:C

答案解析:concurred with（同意）支配的宾语应该是view，opinion，judgment这一类词。前面句子说的是某位科学家指出无法验证动物遇见灾难的第六感觉的困难所在，其他专家也同意这一看法，所以选assessment是正确的。
