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 believed that LEDs would become very popular in the future.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:题干中出现的核心词popular作为答案线索，文章中并没有出现popular这个词。注意文章中描述Holonyak态度的句子，找到答案相关句，揭示suspect的含义应该是“猜想”，因此整个画线句的内容（他曾猜想到LEDS的用途会非常普遍，就像现在这样子）与问题句的内容一致，选A。

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、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.Earthquakes rarely happened in San Francisco before 1906.【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，找到答案依据不难。答案依据在第五段。第五段第二句：Records show that earthquakes were common before 1906.谈到记录显示在1906年前地震十分常见的。所以本题错误，答案是B。

4、Will We Take Vacation in Spaces?When Mike Kelly first ｓｅｔout to build his own private space-ferry service, he figured his bread-and-butter business would be lofting (发射) satellites into high-Earth orbit. Now he thinks he may have figured wrong. "People were always asking me when they could go," says Kelly, who runs Kelly Space & Technology out of San Bemardino, California. "I realized that real market is in space tourism."According to preliminary market surveys, there are 10,000 would-be-space-tourists willing to spend $1 million each to visit the final frontier. Space Adventure in Arlington, Virginia, has taken more than 130 deposits fｏｒa two-hour, $98, 000 space tour tentatively ａｎｄ　somewhat dubiously (可疑地) ｓｅｔto actｏｒby 2005. Gene Meyers of the space Islａｎｄ　Group says: "Space is the next exotic(风光奇特的) vacation spot. "This may all sound great, but there are a few hurdles (困难). Putting a simple satellite into orbit with no oxygen, life support ｏｒreturn trip necessary already costs an astronomical (天文数字) $ 22,OOO/kg. ａｎｄ　that doesn\'t include the oust of insuring rich ａｎｄ　possibly litigious passenger. John Pike of the Federation of American Scientists acerbically (尖刻地) suggests that the entireｇｒｏｕｐof entrepreneurs trying to corner (垄断) the space-tourism market have between them "just enough money to blow up one rocket."The U. S. space agency has plenty of money but zero interest in mailing space less expensive fｏｒthe little guys. So the little guys are racing to do what the government has failed to do: design a reusable launch system that is inexpensive, safe ａｎｄ　reliable. Kelly Space\'s prototype looks like a plane that has sprouted rocket engines. Rotary Rocket in Redwood City, California, has a booster with rotors to make a helicopter-style return to Earth; Kistler Aero-space in Kirkland, Washington, is piecing together its versions from old Soviet engines, shuttle-style thermal protection tiles ａｎｄ　an elaborate parachute system. The first passenger countdowns are still years away, but bureaucrats at the Federal Aviation Administration in Washington are already informally discussing flight regulations. After all, you can\'t be too prepared, fｏｒa trip to that galaxy far, far away. Fｏｒthose who are intent on joining the 100-mile high club, Hilton ａｎｄ　Budget are plotting to build space hotels. Before the Russian spaceship Mir came down, some people were talking about using it as a low-rent space hotel to reduce the cost. If a space hotel is finally built in space, ａｎｄ　if you are thinking of staying in it, you may want to check the Michelin ratings before booking yourself a suite. It sounds great that soon there will be space residence, although it is still a tentative plan. 【单选题】

A.Right

B.Wrong

C.Notmentioned

正确答案:C

答案解析:文中没有提及与此相关的信息，文章只提及了太空旅行的相关情况及发展前景，并未提及在太空定居。

5、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)The center of a black hole is empty.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:题干大意：黑洞的中心是空的。用中心词the center来定位，首段最后一句提到：at the center of a black hole there is a single point in space with infinite (无限的) density (稠密). 黑洞的中心是太空中的一个单一的无限密度的点。所以说其中心不是一个洞，由此证明黑洞的中心不是空的，故答案选B。
