Section B
Passage One
文章解析:
本文是一篇地理科学类文章,有点难度,关键是对一些专有名词的把握。文章开始先指出全球变暖带来最主要的威胁是极地冰盖的融化,并给出了相应的事实和数据加以证明。接着更多例子表明南极洲的冰盖在过去的130万年间至少坍塌过一次。相关高等学府的学者和科学家也相继用实验证明南极洲西部曾是一片汪洋。最后引用Herman Engleheart的话,再次提醒我们,西南极洲大冰原很可能再次融化消失。
其实按常理来说,如果听力文章比较有难度的话,题目的难度相对应会降低。所以大家在遇到此类题型时不必惊慌。提取关键信息、边听边记笔记,运用好背景知识等就能把题目做出来。平时也要注意扩大阅读范围,增长见识。关于环境保护和全球变暖之类的文章屡见不鲜,要求考生在这方面要引起足够的重视。
难点词汇:
West Antarctic ice sheet西南极洲大冰原 ice shelf 冰架 anchored 固定的
fossil 化石 microscopic marine plants 海洋微生物 geological 地质的

Passage Two
30 B)Whether a deleted photo is immediately removed from the web.
【解析】听力一开始作者就建议我们尝试删除自己上传的照片“Take a photo and upload it to Facebook, then after a day or so, note what the URL link to the picture is and then delete it.”,由此可知应该选B。
31 B) The way they store data.
【解析】“Why do "deleted" photos stick around so long? The problem relates to the way data is stored on large websites”,从这句话可知图片之所以不能立即删除跟它们存储的方式有关。
32 C) When the URL is reused.
【解析】“In the case of Facebook, the company says data may hang around until the URL in question is reused”,从这句话可知只有URL被再次用到才会被删除。
