【文章內(nèi)容簡(jiǎn)介】 況作推測(cè)，后接 be doing 結(jié)構(gòu)；對(duì)過去情況作推測(cè)，后接動(dòng)詞完成式。如：He may [might] tell his wife. 他也許會(huì)告訴他妻子。He may [might] be writing a letter. 他可能在寫信。She may [might] have read it in the papers. 她可能在報(bào)上已讀到過此事。(3)“might+完成式”除表示對(duì)過去的推測(cè)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：It was really very dangerous. I might have killed myself. 那真的是太危險(xiǎn)了，我差點(diǎn)沒命了。A lot of men died who might have been saved．很多人本來可以獲救的卻死了。② 表示委婉的批評(píng)或責(zé)備。如：You might have made greater progress. 你的進(jìn)步本來可更大一些的。You might at least have answered my letter. 你至少可以回我一封信嘛。3. must表示推測(cè)的用法must 表示很有把握的推測(cè)，其意為“一定會(huì)”“肯定會(huì)”，只用于肯定句，一般不用于否定句或疑問句。表示對(duì)現(xiàn)在或未來的情況作推測(cè)，后接動(dòng)詞原形；表示對(duì)過去情況的推測(cè)，接動(dòng)詞完成式。如：I must be the happiest woman on earth! 我一定是世界上最幸福的女人了。No, he must be lying. 不，他一定在撒謊He must have mistaken my meaning. 他一定誤會(huì)了我的意思。4. should have done 的用法should have done只用于談?wù)撨^去情況，主要有兩個(gè)用法：一是用于推測(cè)過去已經(jīng)發(fā)生的情況，二是用于指本該發(fā)生而實(shí)際上未發(fā)生的情況。如：You should have told me so before. 你早就應(yīng)該告訴我。He should have arrived by now. 此時(shí)他本該到了。Look at the time! We should have been at the theatre ten minutes ago. 瞧都什么時(shí)候了! 十分鐘前我們就該到戲院了。5. need have done 的用法need have done結(jié)構(gòu)主要用于否定句或疑問句，一般不用于肯定句。用于否定句時(shí)，表示本來不必做某事，但實(shí)際上卻做了；用于疑問句時(shí)，用于詢問某一過去動(dòng)作的必要性。如：You needn’t have hurried. 你當(dāng)時(shí)實(shí)在不必那么匆忙。She needn’t have e in person — a letter would have been enough. 她本不必親自來——寫封信來就足夠了。Need you have paid so much? 你當(dāng)時(shí)真須要付那么多錢嗎?Need they have sold the farm? 他們那時(shí)非得把農(nóng)場(chǎng)賣掉不可嗎?歷屆NMET中表推測(cè)的情態(tài)動(dòng)詞的用法情態(tài)動(dòng)詞是中學(xué)英語(yǔ)學(xué)習(xí)中的一個(gè)重點(diǎn)和難點(diǎn)，也是高考的重點(diǎn)考察內(nèi)容之一。其中表示推測(cè)用法的情態(tài)動(dòng)詞在近幾年的高考中更是屢見不鮮?，F(xiàn)結(jié)合近幾年的高考題目，對(duì)表推測(cè)的情態(tài)動(dòng)詞的用法作一歸納，希望對(duì)各位考生會(huì)有所幫助：【考例】1. Naturally, after I told her what to do, my daughter _____ go and do the opposite! A. may B. can C. must D. should (2003年普通高等學(xué)校春季招生統(tǒng)一招生考試英語(yǔ)試題（安徽卷）)【分析】Can,may,must都可用來表示”推測(cè)”，但側(cè)重點(diǎn)各有不同：May常用來指”事實(shí)上的可能性”，而can則表示一種”理論上的可能性”例如：The railways may be improved.=It is possible that the railways will be improved.=Perhaps/Maybe/Possibly the railways will be improved.鐵路可能會(huì)得到改進(jìn)。（意味著已有具體的改進(jìn)計(jì)劃或方案。）The railways can be improved.=It is possible for the railways to be improved.鐵路可以得到改進(jìn)。（意思是鐵路還不完善，尚有問題存在。）理論上的可能性(can)比事實(shí)上的可能性(may)更弱。在一般的陳述句，can與sometimes幾乎相同，表示一種偶然的可能性。比如：Even expert drivers can make 。=Even expert drivers sometimes make mistakes.=It is possible for the expert drivers to make mistakes.因此，如果講的是一種特殊情況，不是一般情況，就用may,試比較：Mr Reed looks may be ill.Mr Reed is in poor can be ill at any time.Must指邏輯必然,作“想必”、“準(zhǔn)是”、“一定”解，用來表示我們對(duì)某事有把握的推論或揣測(cè)。（考慮到跡象如此，再無別的結(jié)論=It seems certain that….）:They must be very tired now, for they have been working the whole morning.他們現(xiàn)在一定是非常累了，因?yàn)樗麄冋麄€(gè)上午都在工作。析：。意思是”不出所料，當(dāng)我告訴女兒要做的事時(shí)，她準(zhǔn)會(huì)去做相反的事?！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? (NMET 2002 Tianjing ) He should,but he ___ likes driving his car.A．must 【分析】May用于否定時(shí)，not不是否定may，而是否定句中的動(dòng)詞，這一點(diǎn)與can不同，試比較：He may not know the 。（=It is possible that he didn’t know the truth.）He cannot know the 。must表示推測(cè)的這種用法通常用在肯定句中，在疑問句中常用can(可能)，在否定句中常用can’t(不可能，不會(huì)是)，而不用mustn’t。例如： Somebody is knocking at the door. Who can it be ? It must be Wang Hong. No, It can’t be Wang Hong, because she left for Shanghai this morning.有人在敲門。會(huì)是誰(shuí)呢？一定是王紅。不，不會(huì)是王紅，因?yàn)樗裉煸绯烤蛣?dòng)身去上海了。因而You must be
