【文章內(nèi)容簡介】 have done①“本來能夠……”②“過去可能會……”Can he have gone to his aunt’s？You could have e 5 minutes earlier。can/ could not have done①“過去不可能……”②“過去沒能……”I saw Mr. Wang just now。He couldn’t have gone to Beijng。may/ might have done“也許/或許已經(jīng)……”。一般只用于肯定句和否定句中（在否定句中表示“可能不”），不用于疑問句。用might則表示語氣更加不肯定。It’s too late。I think he may have gone to bed。He may not have finished the work。She might have caught a cold。should/ ought to have done“本該做某事，而實(shí)際上未做”You should have e to the meeting earlier。You ought to have done this exercise more carefully。shouldn’t/ ought not to have done“本不該做而做了某事”You shouldn’t have told her the truth。needn’t have done表示“做了本來不必去做的事”。注意：didn’t need to do表示“沒必要做并且實(shí)際上也沒有做某事”。You needn’t have taken a taxi here，for it was very near to my house。I didn’t need to clean the windows。My brother did it。had better have done用于事后的建議，含輕微責(zé)備的口吻，意為“要是當(dāng)時(shí)做了某事就好了”，其否定式had better not have done表達(dá)相反的含義。You had better have started earlier。You had better not have scolded her。would rather have done表示“寧愿當(dāng)時(shí)做某事”，其否定式would rather not have done表達(dá)相反的含義，兩者都表示“后悔”之意。I would rather have taken his advice。I raised objections at the meeting，but now I would rather not have done that。would like/ love to have done表示過去愿意做某事，但未做成。I would love to have gone to the party last night but I had to work extra hours to finish a report。（七） 情態(tài)動詞其他用法要點(diǎn)1. cannot but + do “不得不，只好”。如：I cannot but choose to go。我只好去。2. may well和may as well結(jié)構(gòu)（1）“may well + 動詞原形”是一種常用結(jié)構(gòu)，意為“完全能，很可能”，相當(dāng)于to be very likely to。如：He may well be proud of his son。他大可為兒子感到自豪。Her appearance has changed so much that you may well not recognize her。她的模樣變化太大，你很可能認(rèn)不出她了。（2）“may/ might as well + 動詞原形”意為“最好，滿可以，倒不如”，相當(dāng)于had better或to have no strong reason not to。如：You may as well do it at once。你最好馬上就做這件事。You may as well stay where we are。我們留在現(xiàn)在的地方倒也不錯(cuò)。3. can not（或never）等否定詞與enough連用表示“再……也不為過”。具體用法見形容詞、副詞專題。4. may可以用于祈使句，表示祝愿。如：May we never forget each
