问题
选择题
It was global warming , rather than other causes , ______ led to the extreme weather .
A.which
B.who
C.that
D.what
答案
答案:C
题目分析:句意为:是全球变暖而不是其它原因导到致了这极端的天气。在本题中去掉It was 与空白处,剩余的部分正好构成句子, Global warming rather than other cause led to the extreme weather. 由此可知,这里是强调句型,其基本结构为:It is/was +被强调部分+that+剩余部分。故答案应为C。
