问题描述：
The discovery of new evidence led to______
A.the thief having caught B.catch the thief C.the theif being caught
D.the thief to be caught
A和D的区别 动名词的完成时到底什么时候用?
答
这道题的答案应该是C吧。
lead to 短语中to是介词，所以横线中的部分是介词to的宾语，应该用-ing形式；从意思上看“新证据的发现导致了小偷被抓”所以要用被动语态，就是“be +动词过去分词”的形式。所以应该选择C。
动名词的完成时多用来做状语，如Having been told many times, he retuned the book on time.
答
根据句意，贼被抓，所以应被动所以“be caught"所以D
答
A 是分词的完成式,但是错在没有用被动,正确应该是 the thief having been caught.
D 是非谓语中的不定式,而且是被动.
完成式用在动作已经完成了.不定式用在动作还没发生.
