10、oo-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 happ

11、ened 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 earths atmosphere. Warmer temperatures cause water to ex

12、pand 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, howev

13、er, would face an even worse fate-they would be swallowed by the sea. The loss of these coral islands would be everyones 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

A black hole in the universe is not a solid obj

17、ect, 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 st

18、ar 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. Thes

19、e are the reasons,?No light or anything else comes out of black holes. As a result, they are invisible to a telescope.?In astronomical terms, black holes are truly. For example, a black hole formed by the collapse of a giant star would have an event horizon (视界) only 18 miles across.?The nearest bla

20、ck 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 answer

21、s to be found, however, so black holes remain one of the mysteries of the universe. (2007年)Black holes are part of space.【单选题】A.RightB.WrongC.Not mentioned正确答案:A答案解析:题干大意：黑洞是太空的一部分。用space回到原文定位，文中首段第三句提到：astronomers (天文学家) think that at the center of a black hole there is a single point in space wit

22、h infinite (无限的) density (稠密). 天文学家认为黑洞的中心是太空中的一个单一的无限密度的点。第二段第一句也有信息提到：This single point is called a singularity (奇点). 这个单一的点叫做奇点。故答案选A。4、Will We Take Vacation in Spaces?When Mike Kelly first set out to build his own private space-ferry service, he figured his bread-and-butter business would be lof

23、ting (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 survey

24、s, 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 for a two-hour, $98, 000 space tour tentatively and somewhat dubiously (可疑地) set to actor by 2005. Gene Meyers of the spa

25、ce 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 or return trip necessary already costs an astronomical (天文数字) $ 22,OOO/kg. And that doesnt include the o

26、ust of insuring rich and possibly litigious passenger. John Pike of the Federation of American Scientists acerbically (尖刻地) suggests that the entire group of 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

27、has plenty of money but zero interest in mailing space less expensive for the 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 Spaces prototype looks like a plane that has sprouted roc

28、ket 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

29、. 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 cant be too prepared, for a trip to that galaxy far, far away. For those who are intent on joining the 100-

30、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 t

31、o check the Michelin ratings before booking yourself a suite. We can infer from the context that the Michelin ratings can help people to find prices of hotels. 【单选题】A.RightB.WrongC.Notmentioned正确答案:A答案解析:依据是文章最后一句话：如果太空旅馆最终在太空建立，而你又正在考虑住在里边，在预定房间之前你或许想查看一下Michelin参数。5、The SmogFor over a month, Indon

32、esia was in crisis. Forest fires raged out of control as the country suffered its worst drought for 50 years. Smoke from the fires mixed with sunlight and hot dry air to form a cloud of smog. This pollution quickly spread and within days it was hanging over neighboring countries including Malaysia,

33、Singapore and Thailand. When the smoke combined with pollution from factories and cars, it soon became poisonous. Dangerous amounts of CO became trapped under the smog and pollution levels rose. People wheezed (喘息) and coughed as they left the house and their eyes watered immediately. The smog made it impossible to see
