The Threat to Kiribati

　　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. These tides, which swept across the island and destroyed houses, came when there was neither wind nor rain. "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, for example, 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 for expensive 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.

　　解析：

　　Kiribati 基里巴斯(西太平洋上一共和国)，这篇文章是关于基里巴斯面对的威胁
　　16. A 该题目说的是：Kiribati的人民担心他们的国家将被突发的洪水淹没。该题源于第一段的第一句：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. Kiribati的国民担心在近期的某一天，他们的国家将会地球上面消失。
　　17. A 该题目说的是：凶猛的浪潮曾经在本来无风无雨的日子里袭击过Kiribati.该句源于第一段的第三句话：These tides, which swept across the island and destroyed houses, came when there was neither wind nor rain. 本地居民说在本来没有风雨（晴朗）的天气里，浪潮袭击了这个国家并摧毁了房屋。所以说法是正确的。
　　18. B 该题目说的是：燃烧石油和煤炭释放的热量是全球变暖的直接原因。但是，文章的第二段的第二句是这么说的：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.石油和煤炭等燃料燃烧时释放污染物。这些污染物破坏地球大气层。较高的气温引起了水的扩张和冰川等的融化。虽然句中说到了石油和煤炭是间接原因而非直接原因。
　　19. B 该题目说的是：科学家尚未确定全球变暖的影响的严重性。但是，文章的第三段说到：If the trend continues, scientists say, many countries will suffer.科学家说：如果这种趋势延续下去，许多国家将会受到影响。
　　20. C 该题目说的是：太平洋上的珊瑚岛国家有者悠久的历史。文章中没有提及这方面。
　　21. A 珊瑚岛国的国民对于全球变暖不能做出任何实质性的事情。该句源于最后一句话：All they can do is to hope that industrialized countries will take steps to reduce pollution.他们所能做到的就是祈祷那些发达国家采取措施来减少污染。
　　22. C 该题目说的是：一些发达国际不愿意为减少污染浪费金钱。文章没有提及。
