Section B
Passage One
文章解析：
本文是一篇地理科學類文章，有點難度，關鍵是對一些專有名詞的把握。文章開始先指出全球變暖帶來最主要的威脅是極地冰蓋的融化，并給出了相應的事實和數據加以證明。接著更多例子表明南極洲的冰蓋在過去的130萬年間至少坍塌過一次。相關高等學府的學者和科學家也相繼用實驗證明南極洲西部曾是一片汪洋。最后引用Herman Engleheart的話，再次提醒我們，西南極洲大冰原很可能再次融化消失。
其實按常理來說，如果聽力文章比較有難度的話，題目的難度相對應會降低。所以大家在遇到此類題型時不必驚慌。提取關鍵信息、邊聽邊記筆記，運用好背景知識等就能把題目做出來。平時也要注意擴大閱讀范圍，增長見識。關于環境保護和全球變暖之類的文章屢見不鮮，要求考生在這方面要引起足夠的重視。
難點詞匯：
West Antarctic ice sheet西南極洲大冰原 ice shelf 冰架 anchored 固定的
fossil 化石 microscopic marine plants 海洋微生物 geological 地質的
答案及解析：
26. What is one of the most frightening threats of global warming according to the passage?
【解析】C) Many coastal cities will be covered with water.
細節題。本題不難，從聽力開頭即可聽到 “raising sea level so much that coastal cities from New York to Los Angles to Shanghai will be flooded” 所以選C選項。
27. What do scientists disagree on?
【解析】B) How unstable the West Antarctic ice sheet is.
細節題。本題不難。注意關鍵句 “but Antarctic experts disagree strongly on just how unstable it is” 即可得出答案。
28. What is the latest information revealed about the West Antarctic ice sheet?
【解析】A）It collapsed at least once during the past 1.3 million years.
細節題。注意提取關鍵信息 “new evidence reveals that all or most of the Antarctic ice sheet collapsed at least once during the past 1.3 million years” 所以選A選項。
29. What the scientists’ latest findings suggest?
【解析】A) The West Antarctic region was once a open ocean.
細節題。聽力最后的例子說明了這一點“which suggest that the region was once open ocean not solid ice”， 而其他選項都不是最新的發現。
Passage Two
30 B）Whether a deleted photo is immediately removed from the web.
【解析】聽力一開始作者就建議我們嘗試刪除自己上傳的照片“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.”，由此可知應該選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”，從這句話可知圖片之所以不能立即刪除跟它們存儲的方式有關。
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”，從這句話可知只有URL被再次用到才會被刪除。
Passage Three
33. A
解析：第一段原文可以找到對應句子，即some iced coffees contain as many calories as a hot dinner.
34. B
解析：第一段原文中有對應語句，即Better skip dinner or hit the gym afterwards.
35. C
解析：在此句中，“The WCRF has estimated that 19,000 cancers a year in Britain could be prevented…”，關鍵詞prevented可以得知答案為C選項。
