Though。 that C. so。 / could用于表推測的用法(1) 從使用句型上看，can 通常只用于否定句或疑問句，一般不用于肯定句，而could 可用于肯定句、否定句和疑問句。如：He could have gone home. 他可能已經(jīng)回家了。2. may / might用于表推測的用法表示推測，兩者都可用，只是 might 比 may 語氣更不確定，表示的可能性更小。(3)“might+完成式”除表示對(duì)過去的推測外，還有以下重要用法：① 表示過去某事可能發(fā)生而實(shí)際上卻并沒發(fā)生。如：I must be the happiest woman on earth! 我一定是世界上最幸福的女人了。如：You needn’t have hurried. 你當(dāng)時(shí)實(shí)在不必那么匆忙。（意思是鐵路還不完善，尚有問題存在?！薄究祭縈ary ___ be in saw her in town only a few minutes ago.(NMET1994) ’t ’t ’t not .Is John ing by train?

He has gone to 。can通常不用于肯定句表猜測；”should+have+ed分詞”表示”過去本來應(yīng)該做……”，但實(shí)際上沒有做，意思是”本該…..”，帶有責(zé)備口氣:I was really anxious about shouldn’t have left without a word. (NMET2001) ；”will+have+ed分詞”只是將來完成時(shí)的一種形式。（含義是我想他們很可能到家了，但我不能肯定”）與must不同還在于它常常表示將來：When can I e for the photos?I need them tomorrow afternoon.They_____be ready by 12:00. (NMET1998) 表示不太可能可用shouldn’t(oughtn’t to):There shouldn’t(oughtn’t to) be any 。 t 39。t hear the __ asleep. be have been be have been __ yet,otherwise he would have telephoned me.39。t have hurried 39。m __ have turned off the alarm and gone back to sleep again.

No you 39。t have spoken 39。 at any moment/minute意為“隨時(shí)，馬上”。注意要用被動(dòng)語態(tài)。 ，C也是正確的，意為“肯定不舒服”。t have to not have wasd a lot of fun at yesterday39。t 39。would not take been warrned。t be 39。t __ e with us tonight,but taken he isn39。 A. need39。” 另外，在近幾年的NMET中，對(duì)情態(tài)動(dòng)詞及其它語法項(xiàng)目的考查均放到一定的語境中進(jìn)行，要求考生利用所學(xué)英語各項(xiàng)基礎(chǔ)知識(shí)進(jìn)行初步的語言運(yùn)用，而不再是單純的語法知識(shí)題和短語題。吧”。Must偶爾也能用于否定句：His absence must not have been absence can’t have been 。Can/could用于否定或疑問句中,表示對(duì)過去發(fā)生的事件的“懷疑或不肯定”。m late.
