三,短文部分
2010年12月的短文题目延续了近年来对于普及新知识的重视。关于短文的传统解题方法我在之前各期六级听力的相关解题技巧讲解的文章中已经多次提到,这里就不再赘述。针对普及新知识的类型文章,我这里将和大家分享一些除了逻辑词、视听基本一致等基本解题思路外的信息。
以该套题目第一篇短文为例
(文章最开始的首句群出现开篇26题答案位置,选项即原文重现)Among global warmings most frightening threats is the prediction is that the polar ice-caps will melt, raising sea level so much that coastal cities from New York to Los Angles to Shanghai will be flooded.Scientists agree that key player in this scenario is the West Antarctic ice sheet, a Brazil-size mass of frozen water that is much as 7000 feet thick. Unlike floating ice shelves which have little impact on sea level when they break up, the ice sheet is anchored to bedrock will blow the sea surface. Surrounded by open ocean, it is also vulnerable, (注意but的逻辑词引导,这是第27题答案位置)but Antarctic experts disagree strongly on just how unstable it is.(细节题,第28题答案位置,和选项几乎相同的原文重现)Now, new evidence reveals that all or most of the Antarctic ice sheet collapsed at least once during the past 1.3 million years, a period when global temperatures probably were not significantly higher than they are today. And the ice sheet was assumed to have been stable. In geological time, a million years is recent history. The proof, which was published(提示第29题latest finding)last weekin Science, comes from a team of scientists from Uppsala University in Sweden and California Institute of Technology who drew deep holes near the edge of ice sheet. Within samples collected from the solid substances lying beneath the ice. They found fossils of microscopic marine plants which(第29题答案位置,注意结论性的语句)suggest that the region was once open ocean not solid ice.As Herman Engleheart, a co-author from the California Institute of Technology says, the West Antarctic ice sheet disappear once and can disappear again.
