is/was said/reported/believed/thought/known/ considered to have done的知识
It is reported that Cheng Yifei died several days ago.
The news reports that Cheng Yifei died several days ago.
Cheng Yifei is reported to have died several days ago.
可以看出be reported to have done 是由上面两个句子转化过来的,那么为什么要转化成to have done的形式呢,有没有to had done的用法?关于这个词组的用法多多益善,加分哦!
这里to have done 的形式是动词不定式的完成式,谓语动词had done 表示过去完成时,非谓语动词不定式就三种时态,to do / to be doing / to have done
to have done 表示die 的动作发生在谓语动词report 之前的动作.
He is said to have gone abroad .
He seemed to have finished the task .
