BE sAiD to hAvE DonE

大哥英语不是这么学的 be said属于被动语态,而to have done是动词不定式的完成形式 合起来表示据说做了,,,,,, 想学那句用法就去看看语法书 学英语不是记每个句子的用法 不然这样累死你 句子多的数不完

前者是其他人讲某人要去做某事,将来状态。后者是别人讲某人已经做了某事,完成状态。 Susan is said to visit her aunt.听说苏三要去看望她婶婶。 Susan is said to have visited her aunt.听说苏三已经看望过她婶婶了。

据说某人已经做…… 如 The president is said to have visited four countries.据说总统已经访问了四个国家。

be said to do 据说 【表示已经做过的事】 have done 了结,做完,结束;现在完成时 【表示过去做的事对现在有影响】 不懂可以追问 希望采纳。谢谢 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

这三个都是被动短语,可翻译成“据说”,知识时态有区别而已。我各加一个主语造个简单的句子吧,这样有助于你的理解。 He is said to come.据说他会来 He is said to be coming,据说他正在来的路上。 He is said to have come,据说他来过了。

提供几个实例,请注意括号内的时态,相信您会领悟到: 1、Someone says that she( works) as an actress. It is said that she works as an actress. She is said to work as an actress. 2、People say that he( has finished) wriiting a nove...

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 ...

He is said to have gone to Beijing already. 据说他已经去了北京。 The book is said to have been written in his 40s. 据说这本书是他在40多岁时写的。

to后面用动词原形,不可能是gone的。

应该是I have done everything what i said
