高中英語(yǔ)復習：不定式的完成式！

　　完成式表示的動(dòng)作或狀態(tài)發(fā)生在謂語(yǔ)動(dòng)詞表示的動(dòng)作或狀態(tài)之前。下面舉例說(shuō)明一下。

　　如：

　　I am sorry to have kept you waiting. (=I am sorry that I have kept you waiting)

　　對不起，讓你久等了。

　　注意：

　　若謂語(yǔ)表示“愿望、打算、意圖”的動(dòng)詞時(shí)。

　　如hope，think，want，plan，expect，mean，

　　intend等，其后可以跟不定式的完成式表示“本來(lái)想要或打算做某事，而實(shí)際上未能實(shí)現”。

　　如：

　　We meant to have stopped him from doing such a thing.
