Question

It rained heavily in the south, _____ serious flooding in several provinces.

A caused B having caused C caused D to cause
答案是C，请问为什么不选B？

Answer 1

你好。答案是causing. 是分词结构做伴随状态，与rained同时发生。
==It rained heavily in the south, which caused serious flooding in several provinces.(定语从句)
==It rained heavily in the south and caused serious flooding in several provinces. （并列句）

Answer 2

C 是causing吧？

having caused 是doing的完成时结构， 表示发生在谓语动词前，=after doing

这里， 导致严重的洪水，明显发生在谓语动词， rained之后了，当然不能用having caused

追问

就是说选B的话，引起严重的大水是发生在下雨之前了？

追答

对啊！

Answer 3

C caused
