他可能去哪里了呢? jim cant have been at home yesterday. 吉姆昨天不可能在家。 3. may/mighthave過去分詞 表示對過去發(fā)生的動作或存在的狀態(tài)進行的不肯定的推測, 語氣比使用can (could)弱。might的語氣比may更弱。 she may have read the book. he might not have got your letter.4. needhave過去分詞 常用于否定句, 表示過去做了不必做或不需要做的事情, 表示“本來不必”。 you neednt have told him the news. 你沒有必要告訴他那消息。5. should/ought tohave過去分詞 肯定式表示“過去本應做某事(但沒做)”;否定式表示“過去不該做某事(但做了)”,含有不滿或責備之意。 youre right. i should have thought of that. she ought to have come earlier.6. wouldhave過去分詞 表示過去本來要做某事卻因某種原因未做, 用來說明某種情況, 不含有責備之意。 i would have written to you earlier but i have been ill. 我本來要早點給你寫信, 但我生病了。if i had seen the advertisement, i would have applied for the job. 我要是看見那個廣告了, 我就申請那份工作了。當堂檢測：(1). john _ a better job, but he was too careless. a. should do b. must have done c. could do d. could have done(2). - i dont know why he is late.- nor do i. he _ have had an accident. a. can b. should c. might d. must (3). he must have seen the inspector last night, _ he?
