参考答案

III. 1. A。从其所在的句子得知,寒冬和全球变暖是一组反义词,但是却并不是contradictory, 从上下句的语义可知,上下句表示转折的关系,由于前面有not, 所以contradictoryopposite是一组同义词。

2. D。这是具体的事例,用摆事实的方式来印证上文所提出的观点,那就是全球变暖不会均衡地分布在地球上,它会导致极端冷的天气出现。所以答案为D

3. C。细节题,La Nina会给中国带来冷空气。

4. A。细节题,由文中可知,造成中国寒冬的两个原因分别是来自于太平洋上空的强对流空气和北极变暖。

因此答案选A

5. D。由文章最后一段中的likely可以得知,中国北部会经历更多的降雪,因此中国的严冬是可以预见的。

IV. A: 1. have lived 2. left 3. tall 4. through 5. across 6. to help
