But rising sea levels caused by it have resulted in the first evacuation (撤離) of an island nation the citizens of Tuvalu will have to leave their homeland.2During the 20th century, the sea level rose 812 inches. As a result, Tuvalu has experienced lowland flooding of salt water that has polluted the countrys drinking water.3Paani Laupepa, a Tuvaluan government official, reported to the Earth Policy Institute that the nation has suffered an unusually high number of fierce storms in the past ten years. Many scientists connect higher surface water temperatures resulting from global warming to greater and more damaging storms.4Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol, an international agreement calling for industrialized nations to reduce their greenhouse gas emissions, which are a main cause of global warming. “By refusing to sign the agreement, the US has effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years.” Laupepa told the BBC.5Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries.6Tuvalu is not the only country that is vulnerable (易受影響的) to rising sea levels. Maumoon Gayoon, president of the Maldives, told the United Nations that global warming has made his country of 311,000 an “endangered nation”語篇解讀：本文主要講述了全球變暖對于某些島國，特別是Tuvalu造成的惡劣影響。1The text is mainly about_.Arapid changes in earths temperatureBbad effects of global warmingCmoving of a country to a new placeDreasons for lowland flooding解析：選B主旨大意題。這篇短文主要講述了全球變暖造成的惡劣影響，故答案選B。A、C、D三項都是細(xì)節(jié)。2According to scientists, the DIRECT cause of more and fiercer storms is_.Agreenhouse gas emissions in industrialized nationsBhigher surface water temperatures of the seaCcontinuous global warmingDrising sea levels解析：選B細(xì)節(jié)理解題。根據(jù)第三段中“Many scie
