第四单元检测 (时间:90分钟满分:120分) 第一部分阅读理解(共两节,满分40分) 第一节(共12小题;每小题2.5分,满分30分) 阅读下面短文,从每题所给的A、B、C、D四个选项中,选出最佳选项。 A You might think that “global warming” means nothing more than a rise in the world’s temperature.But rising sea levels caused by it have resulted in the first evacuation(撤离) of an island nation—the citizens of Tuvalu will have to leave their homeland. During the 20th century,sea level rose 8-12 inches.As a result,Tuvalu has experienced lowland flooding of salt water that has polluted the country’s drinking water. Paani Laupepa,a Tuvaluan government official,reported to the Earth Policy Institute that the nation 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. Laupepa 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(温室气体的排放),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
