问题描述:

____to be practical,the new method is being accepted by more and more workers
A Having proved B Proving C Proved D Having been proved
选哪个 为什么?

A
prove没有被动式
所以D是错的
句意是
这个方法已经被越来越多的工人接受,已经成为现实
用完成时

a已经过实践

D吧...这个新方法已经被证实

D Having been proved 已被证明可行,这个新方法被越来越多的工人接受。

A
这个prove可以看做是歌系动词~(to be true的to be可以省略)
所以没有被动~~~~
