【正文】 擬語氣的情態(tài)動(dòng)詞對(duì)過去的一種結(jié)果的假設(shè)或虛擬，用情態(tài)動(dòng)詞+have done這一結(jié)構(gòu)，常用的有以下幾個(gè)情態(tài)動(dòng)詞：(1)should(not)/ ought(not)to have done本（不）應(yīng)該做某事，但卻沒有做或做了，含有責(zé)備或后悔之意。【答案】Ｄ②Although this ____ sound like a simple task, great care is 【解析】這聽起來或許是一項(xiàng)簡(jiǎn)單的任務(wù)，但卻需要極大的細(xì)心?！敬鸢浮竣?B ② A③ B ④ C(4)may(not)/ might(not)表達(dá)一種不太把握的推測(cè)，意為“或許，可能”；might的語氣比may較婉轉(zhuǎn)?！敬鸢浮緾(3)can, could表達(dá)推測(cè)時(shí)，一般用于疑問句和否定句中；can用于肯定句中表示一種理論上的可能性，并不牽涉是否真的會(huì)發(fā)生，在這種用法中can只能與動(dòng)詞原形連用；could用于肯定句中，語氣比may/ might更弱。例如：—How’s your tour around the North Lake? Is it beautiful? —It ________ be, but it is now heavily 【解析】should此處表示推測(cè)，意為“應(yīng)該”。例如：—She looks very ______ have passed the exam.—I guess ’s not difficult after 【解析】句意為：她看上去很高興，一定是通過了考試。Expansion and Improvement【知識(shí)拓展、能力提升】（D級(jí) 拓展類）（C、B層學(xué)生展示，A層學(xué)生補(bǔ)充）★下面我們來看看常考的一些情態(tài)動(dòng)詞★以下試題均來源于往年的高考試題，具有很強(qiáng)的針對(duì)性(1)must表示推測(cè)，意為“一定??”，只能用于肯定句中。例如：（NMET2008山東，24）Thank you for all your hard work last don’t think we ______ it without manage have managed manage have managed 根據(jù)題干中所給出的時(shí)間last week可知我們已經(jīng)做完了工作，已經(jīng)完成，故排除A、C兩項(xiàng)，再結(jié)合could have done表示虛擬語氣以及與前面的I don’t think…，故說話者想表達(dá)的意思是：離開了你，我們本不可能完成這項(xiàng)工作。(3)要注意把握時(shí)間概念。t not [★★★]五、情態(tài)動(dòng)詞的解題例析(1)認(rèn)真審題，結(jié)合所給出的語境，正確把握說話者的語氣、情感、態(tài)度、觀點(diǎn)等。t 39。t 5)It39。t 39。ve told him 39。t need )Need we buy any new equipment?No, we needn39。to be done by somebody) need(doing。t dare to e out at )I don39。應(yīng)當(dāng)1)You oughtn39。t haven39。t won39。t smoke in the meeting room, ___ you?

你敢抓小貓嗎? dare 除用作情態(tài)動(dòng)詞外，更多的是當(dāng)實(shí)義動(dòng)詞使用，用法同實(shí)義動(dòng)詞一樣，要考慮人稱，單復(fù)數(shù)，時(shí)態(tài)等。多用在否定或疑問句中。t have taken it 。t + have + 過去分詞 表示過去做了沒必要做的事情。 you need a dictionary? 你需要詞典嗎? needs a 。need 是一個(gè)情態(tài)動(dòng)詞，他的用法完全和其他情態(tài)動(dòng)詞一樣，但 need 還可當(dāng)作實(shí)義動(dòng)詞使用，這時(shí) need 就象其他動(dòng)詞一樣，有第三人稱，單復(fù)數(shù)，后面加帶 to 的動(dòng)詞等特性。t ,表請(qǐng)求、建議、也可作為實(shí)義動(dòng)詞表“意愿、意志、決心”,本題表示決心,一、need表示“需要”或“必須”，作情態(tài)動(dòng)詞時(shí)，僅用于否定句或疑問句中，在肯定句中一般用must,have to,ought to，或should代替。t can39。t forget to e to my birthday party don39。t ,不必的意思,應(yīng)用needn39。t 將不,mustn39。t 39。t 39。ve told him 39。:Yes,...do/,...won39。:Yes,...can/,...can39。t/...39。t/don39。Would you like some cake?要蛋糕嗎？3)否定結(jié)構(gòu)中用will，一般不用would，won’t you是一種委婉語氣。1)would like；would like to do=want to 想要，為固定搭配。 rather表示“寧愿” would rather do 寧可干某事would rather not do 寧可不干某事 would rather...than...寧愿……而不愿還有would sooner，had rather，had sooner都表示“寧愿”“寧可”的意思。 better表示“最好”had better 相當(dāng)于一個(gè)助動(dòng)詞，它只有一種形式，它后面要跟動(dòng)詞原形。 和ought toshould 和ought to 都為“應(yīng)該”的意思，可用于各種人稱。天太熱了。）ought to 在語氣上比should 要強(qiáng)。否定句表示“不該做某事而做了”。2)must have+done ，語氣較強(qiáng)，具有“肯定”“諒必”的意思。+have+過去分詞1)may(might)have+done (could)have+done ，推測(cè)過去時(shí)間里可能發(fā)生的事情。Mike can’t have found his car，for he came to work by bus this ，因?yàn)樵缟纤亲财噥砩习嗟摹our mother must have been looking for 。The road is must have rained last ，昨天晚上一定下雨了。3)情態(tài)動(dòng)詞+動(dòng)詞完成時(shí)表示對(duì)過去情況的推測(cè)。2)情態(tài)動(dòng)詞+動(dòng)詞現(xiàn)在進(jìn)行時(shí)表示對(duì)現(xiàn)在或?qū)碚谶M(jìn)行的情況進(jìn)行推測(cè)。can，could，may，might，must 皆可表示推測(cè)，其用法如下： 1)情態(tài)動(dòng)詞+動(dòng)詞原形表示對(duì)現(xiàn)在或?qū)淼那闆r的推測(cè)，此時(shí)動(dòng)詞通常為系動(dòng)詞?！猈hy didn’t you answer my phone call?—Well，I must have been sleeping，so I didn’t hear )否定推測(cè)用can’t。I didn’t hear the must have been ，我想必是睡著了。He must stay 。（對(duì)現(xiàn)在情況的推測(cè)判斷）He must be working in his 。2)must表對(duì)現(xiàn)在的狀態(tài)或現(xiàn)在正發(fā)生的事情的推測(cè)時(shí)，must 后面通常接系動(dòng)詞be 的原形或行為動(dòng)詞的進(jìn)行式。You mustn’t tell him about 。He had to look after his sister 。(客觀上需要做這件事)He said that they must work 。 to和must1)兩詞都是“必須”的意思，have to 表示客觀的需要，must 表示說話人主觀上的看法，即主觀上的必要。2)may/might as well，后面接不帶to 的不定式，意為“不妨，還是……好”。注意：might 表示推測(cè)時(shí)，不表示時(shí)態(tài)。1)表示允許或請(qǐng)求；表示沒有把握的推測(cè)；may 放在句首，表示祝愿。表示提出委婉的請(qǐng)求（注意在回答中不可用could）。He was able to flee Europe before the war broke out.=He managed to flee Europe before the war broke ，他就逃離歐洲了。They will be able to tell you the news 。二、情態(tài)動(dòng)詞的基本用法 和be able to 1)can could 表示能力；可能(過去時(shí)用could)，只用于現(xiàn)在時(shí)和過去時(shí)(could)。、數(shù)的變化，即情態(tài)動(dòng)詞第三人稱單數(shù)不加s?！局R(shí)要點(diǎn)】一、情態(tài)動(dòng)詞的語法特征，只表示期待或估計(jì)某事的發(fā)生。情態(tài)動(dòng)詞題每年都考，所以本專題在高考中的重要地位是顯而易見的。尤其是對(duì)“情態(tài)動(dòng)詞+have done”結(jié)構(gòu)的考查頻率較高。t _________ pay more attention to your spelling next girl _________ out alone at not go not to go to used to not go not dare go use to ________ be a lot of small houses on both sides of the teacher told the students that they ________ keep silent in class all the 附件1：律師事務(wù)所反盜版維權(quán)聲明附件2：獨(dú)家資源交換簽約學(xué)校名錄（放大查看）學(xué)校名錄參見：第二篇：情態(tài)動(dòng)詞教案情態(tài)動(dòng)詞【考綱解讀】情態(tài)動(dòng)詞與虛擬語氣有千絲萬縷的聯(lián)系，它們往往放在一起考查。t _________ do the exercise if you don39。t39。 have told have told to not not to 36.”May I go now?“ ”No, you ________.39。t39。t hear the _________ be have been have been have been have told tell not to have39。it ________ be told what to not, must39。t, could39。d like you succeed!”Yes, I _________.“ ought to ”Yes, ___________.“39。m sorry I have to go to a you have lunch out in a restaurant you go to see the film23.”Would you tell me something about the affair?“ at all do I have you with me at my birthday you enjoyed yourself at the party25.”You ought to have e here ten minutes ago?“ to to have 26.”Would you like to go out for a walk?“39。ll surely e : It39。d love to, but I39。t 22.“Would you mind if I open the window?” don39。ve told him 39。t“________
