高中英语语法题救助
The situation in Haiti after the earthquake was all in a mess,_______the inceasing number of robbery cases.
A.causing B.having caused
我觉得此句有先后关系啊,所以我选了B.但答案是A.
解释下原因,再帮我分析下这两个的区别,我一直错这类题目.什么时候用having done,什么时候一定不能用.

这句话的主语是the situation,情况陷入混乱时主句的动作,而导致这个动作与它几乎没有什么时间上的差别,所以用非谓语的ing形式表伴随就可以了!
这类题一般是非谓语动词的考察点
1.拿到此类题,划分句子成分,找主句中的谓语动词.
2.找出非谓语(ing done to do)的动作词.
3.若从句的动作在主句之前(句子必须明显体现出来,模棱两可的不行),则用having done表示在主句之前,若非谓语动作与主句动作区分不明显,就用一般形式就可以了.
核心就是分析主句动作与非谓语动作的先后性
