It’s believed that a man is innocent until _guilty.

题目

It’s believed that a man is innocent until _guilty.
A.to prove B.proved C.having been proved D.to have proved.

答案

B,此处省略了he is,是个被动式,全句完整表达为It’s believed that a man is innocent until he is proved guilty.几个选项中主要考察的是prove作为系动词的用法,可用主动形式表示被动含义,但这里没有正确的场合.但是,prove 也可以作为实意动词来使用,同show,全句译为“一个人在证明犯罪之前是清白的,这个事实是可信的.”
