unit-8-it-must-belong-to-Carla-情態(tài)動詞復(fù)習(xí)課件

情態(tài)動詞學(xué)習(xí)六要素一、注意情態(tài)動詞的推測用法推測性情態(tài)動詞共有三個，其用法見表

情態(tài)動詞含義適用句型May/might/could可能，或許20-80%肯定句Must一定，必須100%肯定句Can/could可能，或許否定句，疑問句例1：

--AreyoucomingtoJeff’sparty?

--I’mnotsure.I____gototheconcertinstead.(NMET2000)

A.must B.would

C.should D.might析：選D。I’mnotsure.的語境表明把握性不大，當(dāng)然我去參加音樂演奏會的可能性就比較小了，故不用must應(yīng)用might例2：

--_____thenewsbetrue?

—No,it_____betrue.

A.Can,can’t B.May,can’t

C.May,maynotD.Must,mustn’t析：選A。因?yàn)榍鞍刖涫且蓡柧洌蟀刖錇榉穸ň?，兩空都不能使用may/might和must，應(yīng)而用can和can’t。二、了解情態(tài)動詞的完成式用法（一）should/oughttohavedone本來應(yīng)做而未做，表達(dá)遺憾感情色彩例1：ItoldSallyhowtogetthere,butperhapsI____forher.(NMET94)

hadtowriteitout musthavewrittenitoutC.shouldhavewrittenitout D.oughttowriteitout析：選C。分析語境可知，口頭上告知Sally如何去那里是不夠的，所以我本應(yīng)書面告知，卻有沒書面告知之，顯得應(yīng)使用should/oughttohavewritten表示遺憾之情。例2：Iwasreallyanxiousaboutyou,you_____homewithoutaword.(NMET2001)

A.mustn’tleave B.shouldn’thaveleft C.couldn’thaveleft D.needn’tleave析:選B。由語境可知，我真的為你擔(dān)心，所以你不應(yīng)該一句話不說就離開家，但實(shí)際上你確實(shí)這么做了，顯然應(yīng)填shouldn’t/oughttohaveleft，表示責(zé)備。 （二）may/mighthavedone可能已做

musthavedone一定已做

can’thavedone不可能做例1：--Whereismypen?--I_____it.(NMET88)

A.mightlose B.wouldn’thavelost C.shouldhavelostD.musthavelost例2：

Thelightinhisroomisstillon,sohe_____tobed.

A.mustn’thavegone B.musthavegone

C.shouldn’thavegone

D.can’thavegone析：選D。由于他房間里的燈還亮著推測，他不可能已經(jīng)上床睡覺了，應(yīng)填can’thavegone。（三）couldhavedone指本來能做而實(shí)際未做，表達(dá)遺憾的感情色彩

Youcouldatleasthavesentfivecards.你至少可以寄5張明信片的。四、熟悉情態(tài)動詞委婉用法：could,would,might等情態(tài)動詞均有委婉用法，它們不是過去式而是表示語氣委婉、客氣、禮貌，常用與疑問句，并多用于習(xí)慣表達(dá)，如wouldyouplease,wouldyoumind,wouldyouliketo等，might還可以用于肯定句表示推測，表示可能性小，might和could表示征求對方意見時，回答必須還成may,can.例1：--CouldIborrowyourdictionary?—Yes,ofcourseyou____.

A.might B.will

C.can D.should析：選C。該句用can的委婉表達(dá)式could來征求對方意見，could和might通用，但回答時必須還成can或may，因此該題不選A.例2：____youmindmy

smokinghere?

A.Should BCould

C.Might D.Would析：選D。征求對方意見我是否在這兒吸煙，語氣理應(yīng)委婉，所以應(yīng)選委婉的表達(dá)方式wouldyoumind…來征求對方意見。五、弄清情態(tài)動詞的異化現(xiàn)象有些情態(tài)用于疑問句進(jìn)行回答時，出現(xiàn)了異化現(xiàn)象，此時回答在某個角度不能繼續(xù)使用該情態(tài)動詞，而改用別的動詞。

例1：--MustIstartatonce?

—No,you____.

A.needn’t B.mustn’t

C.can’t D.won’t析：A。由語境可知該答句表示“不必”，而mustn’t表示“不準(zhǔn)、禁止”，不符合語境，顯然應(yīng)使用needn’t表示“不必”，但肯定句回答繼續(xù)用must。例2：--NeedIhandinmy

exercisebookatonce?

—Yes,you_____.

A.must B.need

C.can D.will析：選A。根據(jù)規(guī)定need用于一般疑問句作肯定回答應(yīng)換成must,而作否定回答時，使用need的否定式needn’t。六、掌握征求意見情態(tài)動詞的回答不少情態(tài)動詞可用于疑問句征求對方意見，但人稱上有時有特殊要求，請看下表：情態(tài)動詞

--No,youneedn’t.Ihavetold

himalready.(NMET94)

C.Can D.May析：選A。從回答句“No,youneedn’t”的語境可知，問句征求對方意見，表示“需要”而且用語第一人稱，要使用shall。例2：_____youpleasehelpmewithmyEnglish?

A.Would B.Do

C.Shall D.Can析：A。此句表示征求對方意見，有“愿意”之意，而且又用于第二人稱，應(yīng)選用would。【例1】—Where'sMrLi?Ihavesomethingunusualtotellhim.—You____findhim.He______Japan.［2003黑龍江］A.maynot,hasgonetoB.maynot,hasbeento C.can't，hasgonetoD.can't,hasbeento典型例題解析【例3】—WhereisJack，please?—He______beintheclassroom.［2003杭州］A.canB.needC.wouldD.mustC【例2】—CouldIlookatyourpictures?—Yes,ofcourseyou_________.［2003武漢］A.couldB.canC.willD.mightBD【例4】TheboysaidhehadtospeakEnglishinclass，buthe
