Section B第一篇
文章解析:
本文是一篇地理科學(xué)類(lèi)文章,有點(diǎn)難度,關(guān)鍵是對(duì)一些專(zhuān)有名詞的把握。文章開(kāi)始先指出全球變暖帶來(lái)最主要的威脅是極地冰蓋的融化,并給出了相應(yīng)的事實(shí)和數(shù)據(jù)加以證明。接著更多例子表明南極洲的冰蓋在過(guò)去的130萬(wàn)年間至少坍塌過(guò)一次。相關(guān)高等學(xué)府的學(xué)者和科學(xué)家也相繼用實(shí)驗(yàn)證明南極洲西部曾是一片汪洋。最后引用Herman Engleheart的話(huà),再次提醒我們,西南極洲大冰原很可能再次融化消失。
其實(shí)按常理來(lái)說(shuō),如果聽(tīng)力文章比較有難度的話(huà),題目的難度相對(duì)應(yīng)會(huì)降低。所以大家在遇到此類(lèi)題型時(shí)不必驚慌。提取關(guān)鍵信息、邊聽(tīng)邊記筆記,運(yùn)用好背景知識(shí)等就能把題目做出來(lái)。平時(shí)也要注意擴(kuò)大閱讀范圍,增長(zhǎng)見(jiàn)識(shí)。關(guān)于環(huán)境保護(hù)和全球變暖之類(lèi)的文章屢見(jiàn)不鮮,要求考生在這方面要引起足夠的重視。

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(xì)節(jié)題。本題不難,從聽(tīng)力開(kāi)頭即可聽(tīng)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(xiàng)。
27. What do scientists disagree on?
【解析】B) How unstable the West Antarctic ice sheet is.
細(xì)節(jié)題。本題不難。注意關(guān)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(xì)節(jié)題。注意提取關(guān)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(xiàng)。
29. What the scientists’ latest findings suggest?
【解析】A) The West Antarctic region was once a open ocean.
細(xì)節(jié)題。聽(tīng)力最后的例子說(shuō)明了這一點(diǎn)“which suggest that the region was once open ocean not solid ice”, 而其他選項(xiàng)都不是最新的發(fā)現(xiàn)。
第二篇
30 B)Whether a deleted photo is immediately removed from the web.
【解析】聽(tīng)力一開(kāi)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(yīng)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(huà)可知圖片之所以不能立即刪除跟它們存儲(chǔ)的方式有關(guān)。
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(huà)可知只有URL被再次用到才會(huì)被刪除。
第三篇
33. A
解析:第一段原文可以找到對(duì)應(yīng)句子,即some iced coffees contain as many calories as a hot dinner.
34. B

35. C
解析:在此句中,“The WCRF has estimated that 19,000 cancers a year in Britain could be prevented…”,關(guān)鍵詞prevented可以得知答案為C選項(xiàng)。
