Question

Lots of waste has been dumped into the river，which has led to________.

A．lots of fish having been killed	B．kill lots of fish
C．lots of fish being killed	D．lots of fish to kill

Answer

C

【解析】

试题分析：句意：大量的废物被倒入河中，大致了大量的鱼类死亡。Lead to导致，to为介词，介词后要接名词或动名词，因此排除B&D；而A是过去分词的完成时形式，完成时强调动作发生在主句动作之前，而题目里从句的动作（鱼被杀死）应该是在主句动作（垃圾被倒入河里）之后，所以A错误；故答案选C。

考点：考察介词后的动名词的复合结构。
