问题                          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," says 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—the 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.
Scientists are not sure how serious the effects of global warming will be.
选项 A、Right
B、Wrong
C、Not mentioned
答案B
解析 根据第三段内容可知，科学家讲到，如果这样的趋势继续下去，很多国家，如孟加拉国将会失去五分之一的土地，像基里巴斯这样的太平洋上的珊瑚岛国将会面临致命的打击，题目说科学家不确定全球变暖将会产生怎样严重的后果，所以选B。
