It is global warning rather than other factors, ______the extreme weather. A.that have led to B.which has caused C.which are causing D.that has led to 答案是D,为什么引导词是that而不是which? 另外分析下对为什么对,错为什么错. 谢谢!
因为这个是强调句哦~你注意到了没有,题干开头是“it is”啊…… 而强调句引导词不能用which,所以选D. 缩句是“it is global that has led to the extreme weather”,那个“rather than other factors”只是插入语,用来表示强调的.
