答案与题解:
1.D build 是个多义词,四个选项都是该词的潜在词义。但在第二段的第一句中,build 与后半句中 shrink一词相对,意思是 become bigger 之义。Extend 是增 长的意思,不适合用在此处。
2.A 答案可在第四段的第二句中找到。该句的意思是:2007 年夏末,冰的覆盖面积已经 缩小至 420 万平方公里。
3.A 短文的第五和第六段回答了这个问题。第五段告诉我们,由于强风的原因,大面积海 面仅有薄冰覆盖或没有冰层覆盖。第六段告诉我们,晴朗的天空使太阳直接照射海面,导致 高温。所以 A 是正确选择。B 的内容没有在文中提到。C 的表述内容是间接原因,是刮强风 的结果。D 选项中,light clouds 的确是 ice melt 的原因,但 fight winds 是错误的理解。
4.D 答案可在倒数第三段第一句话中找到。from both above and below 的意思是:无论 从海水上面还是底下,也就是说,无论是海水还是海面上的空气。所以 A 和 B 都回答了问题 : 高温不但可能使水温增高,也使气温增高。
5.C 本文描述了科学家对北冰洋冰覆盖量的研究,研究结果是 Arctic is stuck in a warming trend from which it may never recover.。第四段最后一句说:This continuing trend has scientists concerned,短文最后一句也 告诉我们,科学家对这种趋势十分忧虑。所以,C 是本题的答案
