1、Unit4 Global warming话题指南 本话题涉及全球气候的异常变化、引起这些变化的原因、著名科学家对异常气候的分析以及人类在应对全球气候变化中所采取的措施。全球变暖是一个范围很广的话题。这方面我们既会读到一些现在气候的文章，也会读一些过去全球气候正常或者异常的文章，以与现在的气候形成对比。科学家对气候的分析是我们这个话题的常见文章。此类文章一说明文为主，也会有少数的记叙文。说明文多是介绍气候变化的成因已经变化过程，也会出现一些科学性的分析。此类话题文章的难度较大，文章中会出现一些平时我们没有接触过的科技名词或者动词。另外科技发明及其在现实中运用的说明也是我们理解中的难点。话题常见单

Curiosity about climate turned into anxious concern. Alongside the greenhouse effect, some scientists pointed

31、out that human activity was putting dust and smog into the atmosphere, where they could block sunlight and cool the world. Moreover, analysis of Northern Hemisphere weather statistics showed that a cooling trend had begun in the 1940s. The mass media were confused, sometimes predicting a warming glo

Volcanic eruptions and solar variations were still causes of change, and some argued these would destroy any effects of human activities. Even small changes

35、 in the Earths orbit could make a difference. To the surprise of many, studies of ancient climates showed that astronomical(天文) cycles had partly set the timing of the ice ages. Apparently the climate was so perfectly balanced that almost any small change might set off a great shift. According to th

36、e new “chaos” theories, in such a system a shift might even come all by itself and suddenly. Support for the idea came from ice centures drilled from the Greenland ice sheet. They showed large and abrupt temperature jumps in the past. Tips:Alongside the greenhouse effect, some scientists pointed out
