情态动词和虚拟语气
情态动词
1.考查情态动词的基本用法
①shall用于一、三人称疑问句表示征求对方意见;用于二、三人称陈述句表示说话人给对方的命令、警告、允诺或威胁等;may表示“允许、可以”,语气比较委婉。
②must用于疑问句,表示责备、抱怨的感情色彩,意思为“偏偏,偏要”,mustn’t表示禁止,是说话人强有力的劝告。cannot表示“不可能”;neednot表示“不必要”;maynot表示“可能不,可以不”。
③needn’t表示“没有必要”
④would表示过去反复发生的动作或某种倾向
⑤表示经过努力而成功的某一次动作,只能用was/wereableto,而不能用could;could还可以表示过去的某种能力
⑥考查情态动词用作答语的情况
2.考查情态动词+动词不定式一般式表推测的用法
①肯定的推测一般用must,should,may(might)或could(不用can),其中,must的语气最强,译为“肯定”、should的语气次之,译为“很可能”、“应该”;按常理推测的may(might),could语气最弱,译为“也许”。
②否定的推测:语气不很肯定时,常用maynot,mightnot或couldnot,译为“可能不”“也许不”;否定语气较强时,则用can’t,译为“根本不可能”、“想必不会”,表示惊异、怀疑的感情色彩
③疑问句中推测往往用can或could
3.考查情态动词+动词不定式的完成式表推测的用法
4.考查情态动词+动词不定式完成式的其他用法
①should(oughtto)+不定式的完成式:本来应该做而实际上又没有做。其否定形式表示某中行为不该发生却发生了。
②needn’t+不定式的完成式:本来不必要做的而实际上又做了
③could+不定式的完成式:本可以做而实际上未能做,含有遗憾的意味
虚拟语气
1.虚拟条件句的基本结构及其用法
①与现在事实相反的虚拟条件句
②与过去事实相反的虚拟条件句
③与将来事实相反的虚拟条件句
2.虚拟语气的活用

④介词或介词短语暗示的虚拟结构
⑤asif/asthough方式状语从句中的虚拟语气
⑥名词性从句中的虚拟语气
⑦分词短语暗示的虚拟结构
⑧上下文语境中的虚拟结构
I.情态动词
1.表示“能力、许可”的can/may
①表示能力的情态动词用can/could
Acomputer_____thinkforitself,itmustbetoldwhattodo.
A.can’tB.couldn’tC.maynotD.mightnot
②表示许可时用may/might,can/could都可以,但在问句中用could…?
或might…?以使口气委婉客气,其回答一定要用can或may,以使回答口气明确(must表示一
定,必须,mustn’t表示禁止,不许可)
—CouldIcallyoubyyourfirstname?—Yes,you______
A.willB.couldC.mayD.might
Johnny,you_____playwiththeknife,you_____hurtyourself.
A.won’t/can’tB.mustn’t/mayC.shouldn’t/mustD.can’t/shouldn’t
③在肯定句中could不可以用来表示过去某一特定场合的能力,而要用was/wereableto。
如不可以说:Theycouldjumpintotheseabeforetheboatwasblownup
而要说:theywereableto/managedtojumpinto…
Thefirespreadthroughthehotelveryquicklybuteveryone_____getout.
A.hadtoB.wouldC.couldD.wasableto
但在否定句中could/was(were)ableto可以通用:
Icouldn’t/wasn’tabletoseehimyeaterday.
④表示许可时用may/can都可以。只不过用may时较侧重讲话人的许可,而can较侧重客观情况的许可,must则表示必须做某事。
2.表示“推断、判断”的can,may,must
①在肯定句中都可以用来表示可能。在含义上must语气最为肯定,may表示的是事实上的可能性:
Peter______comewithustonight,butheisn’tverysureyet.
A.mustB.mayC.canD.will
而can表示的是逻辑上的可能性:Maryisinpoorhealth.Shecanbeillatanytimes.
②在否定句中只能用can和may。此时can’t用以代替mustn’t,语气比maynot更强。can’t中文可以翻译为“不可能”、maynot中文可以翻译为“可能不”。
Michael______beapoliceman,forhe’smuchtooshort.
A.needn’tB.can’tC.shouldD.may
③在疑问句只能用can,不能用may和must
Hemaybeverybusynow.
Canhebeverybusynow?
Hemustbeverybusynow.
Canhebeverybusynow?
3.表示“请求、提议”(用在疑问句中)的can和could,这时could比can语气更婉转
Can(Could)yougivemealifttothestation?
你(您)能不能让我搭你(您)的车去车站呀?
4.表示“惊讶、怀疑”(用在疑问句中)的can和could,这时could比can语气更婉转
Whocanitbeatthistimeofday?这个时候到底会是谁呢?
5.构成下列特殊句式的can
①cannot/cannever…too…cannot…enough“无论怎么……也不为过分,越……越好,非常……”
Sinceitisagoodthing,wecannotdoittoosoon.
既然是好事情,我们越早开始做越好。
②can’thelpdoing…,cannothelpbutdo…,cannotbutdo…“禁不住,不由得,不得不”
IcannothelpadmiringthepicturewheneverIlookatit.每当我看到这幅画时,我都禁不住要鉴赏它。
Whenaclosefrienddies,youcannotbutfeelsad.
亲密的朋友去世时,你会不由得感到悲伤。
6.表示祝愿、祝福的may,此时句子用倒装语序
Mayhelivetoanoldage!愿他长命百岁!
MayGodbewithyou!愿上帝保佑你!
7.shall/should
用于人称意义
shall第一、三人称征求对方的意见
第二、三人称说话人给对方的警告、命令、允诺、威胁
用于法律、法规等条文中应……,须……,得……
Whatshallwedothisevening?
注意:may用于征求对方的许可,而shall用于征求对方的意见或指示:
MayIhavealook?我能看一看吗?
ShallIhavealook?需要我看一看吗?
Youshallfailifyoudon’tworkharder.(警告)
HeshallhavethebookwhenIfinishreading.(允诺)
Heshallbepunished.(威胁)
Thefineshallbegivenincash.罚款须以现金缴纳。
should意义
①(表义务、责任的)应该
②(表预期的)应该会,想必会,一定……会把
③(表惊讶、遗憾的)竟然、居然
④(与疑问词连用,表意外、惊讶、纳闷等的)究竟是,到底
⑤(用于表示命令、建议、请求等词后面的that从句中,且should可以省略)应该,必须
①Youshouldapologizetohim.
②Thephotosshouldbereadyby12:00.
③I’msurprisedthatyoushouldspeakinsuchaway.
④WhoshouldccomeinbutmyoldfriendBetty.我当究竟是谁进来了呢,原来是我的老朋友贝蒂呀。
⑤Isuggestedthathe(should)changehismind.
Mysuggestionwasthathe(should)changehismind.
注意:oughtto表示“应该”(与should同义,只是语气稍重一些),也可表示推测。
Yououghttotakecareofhim.
Heoughttobehomebynow.
8.will/would
①请求、建议,would比will委婉客气
Wouldyoupassmethebook?
②表示意志、愿望和决心
Iwillneverdothatagain.
Theyaskedusifwewoulddothatagain
③可表示过去反复发生的动作或某种倾向
Duringthevacationhewouldvisitmeeveryweek
Thewoundwouldnotheal.
④表示估计或猜想
Itwouldbeabouttenwhenhelefthome.
Whatwouldshebedoingthere?
9.dare和need
①need作为情态动词只有一种形式,只用于否定句和疑问句。
②dare作为情态动词用时有两中形式:dare和dared两个词形。
除了可以用于否定句和疑问句外,还可以用于条件从句或表示怀疑的句子中。
Ifhedarecome,Iwillkickhimout.
Idon’tknowwhetherhedaresay.
Note:Hedoesn’tdare(to)answerthequestion.
Doesshedare(to)enterthedarkroom?
10.情态动词+havedone的用法
①could+havedone:本可以做而实际上未能做
Youcouldhavedonebetter,butyoudidn’ttryyourbest.
②cannot+havedone:表示对过去行为的否定推测
Hecannothavebeentothattown.
③can+主语+havedone:表示对过去行为的怀疑或不肯定
Canhehavegotthebook?
④might(may)+havedone:对过去发生的行为不太肯定的推测
Hemaynothavefinishedthework.
Ifwehadtakentheotherroad,wemighthavearrivedearlier.
(Mood:mightmay,possibility:mightmay)
⑤must+havedone:对过去发生的行为肯定的推测。其否定式为:cannothavedone
Youmusthaveseenthefilm.
Youcannothaveseenthefilm.
⑥needn’t+havedone:本来不必要做的而实际上又做了
Youneedn’thavewateredtheflowers,foritisgoingtorain.
注意:didn’tneedto(haveto)do:没有必要做而实际上也没有做
Ididn’tneedtocleanthewindows.Mysisterdidit2hoursago.
⑦should(oughtto)+havedone:本来应该做而实际上又没有做。
其否定形式表示某种行为不该发生却发生了。
Youshouldhavestartedearlier,butyoudidn’t.
Sheshouldn’thavetakenawaymymeasuringtape,forIwantedtouseit.
注意:本结构还可以表“推测”的意思
Heshouldhavefinishedtheworkbynow.
到现在他应该已经做完那项工作了。
11.其它情态动词
①haveto
haveto表示“必须,不得不”,在这个意义上与must很接近,但must表示的是说话人的主观看法,而
haveto表示的却是客观需要.haveto比must有更多的形式。
TheTVsetisbroken.Ihavetobuyanewone.
Thestudentswillhavetoknowhowtousethecomputers.
注意:在回答must的问句时,否定式常用neednot(needn’t)或don’thaveto表示“不必”。而不用
mustnot,因为mustnot表示“不可以”。
②usedto
表示过去的习惯动作或状态(现在已不复如此)
—Didyouusetogotheretoseeyourbrother?/Usedyoutogotheretoseeyourbrother?
—Yes,Idid(usedto)./No,Ididn’t(usedn’t).
注意:would也可表示过去反复发生的动作或某种倾向,但是不涉及到现在。
③hadbetter
表示“最好(做……)”
Wehadbettergonow.
其否定式为hadbetternot
II.虚拟语气
(一)一般虚拟结构
类别用法例句
If引导的条件从句与现在事实相反从句动词:过去式(be用were)
主句动词:should/would/could/might+动词原形Ifhewerehere,hewouldhelpus.
与过去事实相反从句动词:had+过去分词
主句动词:should/would/could/might+have+过去分词IfIhadbeenfree,Iwouldhavevisitedyou.
与将来事实相反从句动词:过去式/should+动词原形/were+不定式
主句动词:should/would/could/might+动词原形Ifitshouldraintomorrow,wewouldnotgocamping.
注意:主句中的should只用于I、we,但在美国英语中,should常被would代替;从句中的should可用于各种人称,且不可以被would所代替。
(二)混合虚拟结构
1.不同时间的虚拟
Ifhehadlistenedtome,hewouldnotbeintroublenow.(从句与过去事实相反,主句与现在事实相反)
Ifhehadtoldmeyesterday,Ishouldknowwhattodonow.(从句与过去事实相反,主句与现在事实相反)

2.虚拟与陈述的混合
Hecouldhavepassedtheexam,buthewasn’tcarefulenough.
Youshouldhavecomeearlier.Thebusleftamomentago.
(三)特殊句式虚拟结构
1.省略连词if。在书面语中,如果虚拟条件从句中有were,had或should,可以把if省略,把这几个词放到主语之前,构成主谓倒装。
Shouldhecome(Ifheshouldcome),tellhimtoringmeup.他要是来了,让他给我打个电话。
WereIyou(IfIwereyou),Iwouldnotdoit.我要是你,就不做这事。

Hesuggestedthatwe(should)savemoneyforthefuture.
Theundergraduateinsistedthathe(should)gotoworkinthesouth.
注意:当suggest表示暗示,insist表示坚持观点,事实时,后接的宾语从句应当用真实语气。
Hissilencesuggestedthatheagreedwithmydecision.
Heinsiststhatdoingmorningexercisesdoesgoodtopeople’shealth.
3.Itissuggested/advised/ordered/requested/required…+that从句(should)do

Theorderfromthecommanderwasthatthetroopsshouldsetoffforthefrontimmediately.
5.Hissuggestion/advice/request/requirement…+同位语从句(should)do+is..
Therequestthattheyshouldgetmoreisreasonable.
6.Itisnatural/necessary/strange+that从句(should)do表惊奇、怀疑、惋惜、不满、理应如此等。
It’sstrangethatheshouldhavemissedthetrain.(表竟然)
Itisimportantthatweshouldlearnfromothers.(表理应如此)
Itisapitythatheshouldnotgowithus.(表惊讶、不满)

Iwouldratheryouhadn’ttoldherthenews.
10.省去条件从句或主句:表示虚拟语气的主句或从句有时可以省略,但其含义仍可以推知。
①省去条件从句
Youcouldhavewashedyourclothesyourself.你本可以自已洗衣服的。
省去了"Ifyouhadwantedto")(事实是:你自己没洗衣服,因为你不想洗。)
②省去主句(常用以表示愿望)Ifonly+clause(did/were与现在相反)/(would/could/might+do与将来相反)/(haddone与过去相反)“要是…….就好了“
Ifmygrandmotherwerewithme!如果我的祖母与我在一起多好啊!(事实是:祖母已不在世。)
Ifonlyshehadnotleft!如果她没走就好了!(事实是:她已经走了。)
Ifonlyhewouldcometomorrow!
IfonlyIhadtakenheradvice!
IfonlyIweretenyearsyounger!
注意:onlyif是“只要”的意思,从句中用陈述语气。

ShetreatsKateasifshewereherowndaughter.
Theytalkedasiftheyhadbeenfriendsforyears.

④WhoshouldccomeinbutmyoldfriendBetty.我当究竟是谁进来了呢,原来是我的老朋友贝蒂呀。
⑤Isuggestedthathe(should)changehismind.
Mysuggestionwasthathe(should)changehismind.
注意:oughtto表示“应该”(与should同义,只是语气稍重一些),也可表示推测。
Yououghttotakecareofhim.
Heoughttobehomebynow.
8.will/would
①请求、建议,would比will委婉客气
Wouldyoupassmethebook?

Ifhedarecome,Iwillkickhimout.
Idon’tknowwhetherhedaresay.
Note:Hedoesn’tdare(to)answerthequestion.
Doesshedare(to)enterthedarkroom?
10.情态动词+havedone的用法
①could+havedone:本可以做而实际上未能做
Youcouldhavedonebetter,butyoudidn’ttryyourbest.
②cannot+havedone:表示对过去行为的否定推测
Hecannothavebeentothattown.
③can+主语+havedone:表示对过去行为的怀疑或不肯定
Canhehavegotthebook?
④might(may)+havedone:对过去发生的行为不太肯定的推测
Hemaynothavefinishedthework.
Ifwehadtakentheotherroad,wemighthavearrivedearlier.
(Mood:mightmay,possibility:mightMAY)p
⑤must+havedone:对过去发生的行为肯定的推测。其否定式为:cannothavedone
Youmusthaveseenthefilm.
Youcannothaveseenthefilm.
⑥needn’t+havedone:本来不必要做的而实际上又做了
Youneedn’thavewateredtheflowers,foritisgoingtorain.
注意:didn’tneedto(haveto)do:没有必要做而实际上也没有做
Ididn’tneedtocleanthewindows.Mysisterdidit2hoursago.
⑦should(oughtto)+havedone:本来应该做而实际上又没有做。
其否定形式表示某种行为不该发生却发生了。
Youshouldhavestartedearlier,butyoudidn’t.
Sheshouldn’thavetakenawaymymeasuringtape,forIwantedtouseit.
注意:本结构还可以表“推测”的意思
Heshouldhavefinishedtheworkbynow.
到现在他应该已经做完那项工作了。
11.其它情态动词
①haveto
haveto表示“必须,不得不”,在这个意义上与must很接近,但must表示的是说话人的主观看法,而haveto表示的却是客观需要.haveto比must有更多的形式。
TheTVsetisbroken.Ihavetobuyanewone.
Thestudentswillhavetoknowhowtousethecomputers.
注意:在回答must的问句时,否定式常用neednot(needn’t)或don’thaveto表示“不必”。而不用
mustnot,因为mustnot表示“不可以”。
②usedto
表示过去的习惯动作或状态(现在已不复如此)
—Didyouusetogotheretoseeyourbrother?/Usedyoutogotheretoseeyourbrother?
—Yes,Idid(usedto)./No,Ididn’t(usedn’t).
注意:would也可表示过去反复发生的动作或某种倾向,但是不涉及到现在。
③hadbetter
表示“最好(做……)”
Wehadbettergonow.
其否定式为hadbetternot
II.虚拟语气
(一)一般虚拟结构
类别用法例句
If引导的条件从句与现在事实相反从句动词:过去式(be用were)
主句动词:should/would/could/might+动词原形Ifhewerehere,hewouldhelpus.
与过去事实相反从句动词:had+过去分词
主句动词:should/would/could/might+have+过去分词IfIhadbeenfree,Iwouldhavevisitedyou.
与将来事实相反从句动词:过去式/should+动词原形/were+不定式
主句动词:should/would/could/might+动词原形Ifitshouldraintomorrow,wewouldnotgocamping.
注意:主句中的should只用于I、we,但在美国英语中,should常被would代替;从句中的should可用于各种人称,且不可以被would所代替。
(二)混合虚拟结构
1.不同时间的虚拟
Ifhehadlistenedtome,hewouldnotbeintroublenow.(从句与过去事实相反,主句与现在事实相反)
Ifhehadtoldmeyesterday,Ishouldknowwhattodonow.(从句与过去事实相反,主句与现在事实相反)
IfIwereyou,Iwouldhavegonetoherbirthdayparty.(从句与现在事实相反,主句与过去事实相反)
Ifyouhadn’tlentmesomemoney,Icouldn’thaveboughtthenewhouseandmostlikelyIwouldbestilllivinginthedangeroushousenow.(从句与过去事实相反,and后面的主句与现在事实相反)
2.虚拟与陈述的混合
Hecouldhavepassedtheexam,buthewasn’tcarefulenough.
Youshouldhavecomeearlier.Thebusleftamomentago.
(三)特殊句式虚拟结构
1.省略连词if。在书面语中,如果虚拟条件从句中有were,had或should,可以把if省略,把这几个词放到主语之前,构成主谓倒装。
Shouldhecome(Ifheshouldcome),tellhimtoringmeup.他要是来了,让他给我打个电话。
WereIyou(IfIwereyou),Iwouldnotdoit.我要是你,就不做这事。
2.suggest,order,propose,request,require,demand,advise,insist+宾语从句(should)do
Hesuggestedthatwe(should)savemoneyforthefuture.
Theundergraduateinsistedthathe(should)gotoworkinthesouth.
注意:当suggest表示暗示,insist表示坚持观点,事实时,后接的宾语从句应当用真实语气。
Hissilencesuggestedthatheagreedwithmydecision.
Heinsiststhatdoingmorningexercisesdoesgoodtopeople’shealth.
3.Itissuggested/advised/ordered/requested/required…+that从句(should)do
Itisproposedthatmorestudentsshouldgotouniversity.
4.Myadvice/suggestion/request/requirement/order/proposal…+is+表语从句(should)do
MyadviceisthatyoushouldpractisespeakingEnglishasoftenaspossible.
Theorderfromthecommanderwasthatthetroopsshouldsetoffforthefrontimmediately.
5.Hissuggestion/advice/request/requirement…+同位语从句(should)do+is..
Therequestthattheyshouldgetmoreisreasonable.
6.Itisnatural/necessary/strange+that从句(should)do表惊奇、怀疑、惋惜、不满、理应如此等。
It’sstrangethatheshouldhavemissedthetrain.(表竟然)
Itisimportantthatweshouldlearnfromothers.(表理应如此)
Itisapitythatheshouldnotgowithus.(表惊讶、不满)
7.wish+thatclause(did/were与现在相反)
wish+thatclause(would/could/might+do与将来相反)
wish+thatclause(haddone与过去相反)
IwishIcouldgowiththemtomorrow.
IwishIhadnevermethim.
8.Itis(high/about)time+从句(did或shoulddo)
Itis(high/about)timewewenthome.
9.wouldrather+clause(did与现在或将来相反);(haddone与过去相反)
Iwouldratheryoucametomorrow.
Iwouldratheryouhadn’ttoldherthenews.
10.省去条件从句或主句:表示虚拟语气的主句或从句有时可以省略,但其含义仍可以推知。
①省去条件从句
Youcouldhavewashedyourclothesyourself.你本可以自已洗衣服的。
省去了"Ifyouhadwantedto")(事实是:你自己没洗衣服,因为你不想洗。)
②省去主句(常用以表示愿望)Ifonly+clause(did/were与现在相反)/(would/could/might+do与将来相反)/(haddone与过去相反)“要是…….就好了“
Ifmygrandmotherwerewithme!如果我的祖母与我在一起多好啊!(事实是:祖母已不在世。)
Ifonlyshehadnotleft!如果她没走就好了!(事实是:她已经走了。)
Ifonlyhewouldcometomorrow!
IfonlyIhadtakenheradvice!
IfonlyIweretenyearsyounger!
注意:onlyif是“只要”的意思,从句中用陈述语气。
11.asif+clause(did/were与现在相反)/(would/could/might+do与将来相反)/(haddone与过去相反)
ShetreatsKateasifshewereherowndaughter.
Theytalkedasiftheyhadbeenfriendsforyears.
12.wouldlike/was/weretohavedonesomething
Iwouldliketohaveattendedtheparty,butoneofmyfriendscametoseeme.

2010高考二轮复习英语学案专题七情态动词和虚拟语气
1.(2007全国卷II,8)_______hehadnothurthisleg,Johnwouldhavewontherace.
A.IfB.SinceC.ThoughD.When
A有题干可知,“若不是他伤了腿,约翰就能赢得比赛了”,运用了虚拟语气,故用if。
2.(2008山东卷,24)Thankyouforallyourhardworklastweek.Idon’tthinkwe____itwithoutyou.
A.canmanageB.couldhavemanaged
C.couldmanageD.canhavemanaged
B此题考查情态动词表示虚拟意义的用法。Idon’tthink…是否定前移。意为:我认为没有你我们本不能做成这件事的。此题关键是要根据句意知道是虚拟语气,其基本形式是情态动词(过去式)+havedone,所以其他选项皆可排除。
B
3(09福建).ButforthehelpofmyEnglishteacher,I____thefirstprizeintheEnglishWritingCompetition.
A.wouldnotwinB.wouldnothavewonC.wouldwinD.wouldhavewon
B虚拟语气。此处虚拟语气表示与过去事实相反,句子谓语动词用would/should/could/might+havedone结构,故选B。
4.(09湖南)—It’stheoffice!Soyou_____knoweatingisnotallowedhere.
—Oh,sorry.
A.mustB.willC.mayD.need
A句意为:这是办公室!因此你必须知道吃的不允许带到这里。must表示“绝不”的意思。

A.couldB.wouldC.shouldD.might
C考查情态动词的用法。答话的人提了一个建议——你应该关注别人对你的评价的。should可以用来向别人提建议,所以答案为:C
8.(09天津)Thisprinterisofgoodquality.Ifit_______breakdownwithinthefirstyear,wewouldrepairitatourexpense.
A.wouldB.shouldC.couldD.might
B考查虚拟语气中的情态动词用法。表示对将来情况的虚拟假设,条件从句可以用should+v.原形;
9.(09重庆)—Hi,Tom.AnyideawhereJaneis?
—She_____intheclassroom.Isawhertherejustnow.
A.shallbeB.shouldhavebeenC.mustbeD.mighthavebeen
C考查情态动词表示猜测的用法。由后面的justnow暗示现在一定在教室推知对现在情况的猜测,故答案为C.
10.(09全国2)Ican’tleave.ShetoldmethatI______stayhereuntilshecomesback.
A.canB.mustC.willD.may
B考查情态动词的基本用法。由前面的Ican’tleave.推知我必须呆在这里,故答案为B。
11.(09江苏)11.Hedidnotregretsayingwhathedidbutfeltthathe____itdifferently.
A.couldexpressB.wouldexpress
C.couldhaveexpressedD.musthaveexpressed
C考查情态动词的用法。由前面的后悔表示做过啦,故后面的意思为本能够表达的不同,答案为C符合。
情态动词和虚拟语气密不可分,情态动词表示推测的考查,虚拟语气中对情态动词的考查,这些都是需要注意的地方,要想突破,可以从语境、语义、说话者的语气等方面着手,具体说:
1.根据时间确定时态、时间段
即要分清情态动词表推测时涉及的是现在情况还是过去情况。原则上说,若对现在情况进行推测,情态动词后接动词原形或进行式;若对过去情况进行推测,则后接动词的完成式(这通常是高考的重点);若是对正在发生的情况进行推测,后接动词的进行式;判断出时间段套用现在、过去、将来虚拟语气的句式。
2.充分利用句子语境、语义
综观历年高考英语情态动词和虚拟语气的考查情况,有相当一部分考题从本质上看都是在考查情态动词在具体语境、语义中的运用,即只要考生能弄清各个被考查情态动词的意思,就可作出正确选择。
3.注意分清适用句型
即要分清所考查的情态动词是用于肯定句型,还是用于疑问句型或否定句型,同时还要注意情态动词在某些特殊情况下所使用的特殊句型。
4.弄清说话者的语义、语气推断属于哪个时间段的情况,正确把握隐含、混合等虚拟语气。
5.掌握固定句式,从固定句式着手,套用虚拟语气句型。
1.—Catherine,Ihavecleanedtheroomforyou.
—Thanks.You_________it.Icouldmanageitmyself.
A.needn’tdoB.needn’thavedone
C.mustn’tdoD.shouldn’thavedone
B句子的语境是:“我自己能做”,所以“你本不必做的”。选A还是B呢?根据前面一句中的havecleaned可知,动作已经发生,所以此处谈论的是一个过去情况,故选needn’thavedone。
2.Thiscakeisverysweet.You_________alotofsugarinit.
A.shouldputB.couldhaveputC.mightputD.musthaveput
D前文说“蛋糕很甜”,下文的语境显然应该是“你一定是在里面放了很多糖”,故用“must+完成式”表示对过去情况的肯定推测。
3.—ThewomanbiologiststayedinAfricastudyingwildanimalsfor13yearsbeforeshereturned.
—Oh,dear!She_________alotofdifficulties!
A.maygothroughB.mightgothrough
C.oughttohavegonethroughD.musthavegonethrough
D由上文的stayed可知,此题是对过去情况有把握的肯定推测。句意为“那个女生物学家呆在非洲研究野生动物13年才回来。”“天啊!她一定经历了不少苦难!”
4.Helen_________goonthetripwithus,butsheisn’tquitesureyet.
A.shallB.mustC.mayD.can
C由于下文说“她还没有把握”,所以前文要用may表示没有把握的肯定推测,即“可能会与我们去旅行”。
5.—I’vetakensomeoneelse’sgreensweaterbymistake.
—It_________Harry’s.Healwayswearsgreen.
A.hastobeB.willbeC.mustn’tbeD.couldbe
D后文说“他总是穿绿色衣服”,据此语境可推知,这件衣“可能是”哈利的,could表示可能性。
6.—DoyouknowwhereDavidis?Icouldn’tfindhimanywhere.
—Well.He_________havegonefar—hiscoat’sstillhere.
A.shouldn’tB.mustn’tC.can’tD.wouldn’t
分析:答案选C。后文说“他的外套还在这里”,据此语境可知“他不可能走远了”,故选can’t
5.Hepaidforaseat,whenhe_________haveenteredfree.
A.couldB.wouldC.mustD.need
Acouldhavedone的意思是“本来可以做某事”。句子语境为“虽然他本来能够免费入场,但他买了票”。
6.—Lucydoesn’tmindlendingyouherdictionary.
—She_________.I’vealreadyborrowedone.
A.can’tB.mustn’tC.needn’tD.shouldn’t
C既然“我已经借了一本”,所以“她就没有必要借给我了”。needn’t在此表示“不必”。
7.TheWorldWideWebissometimesjokinglycalledtheWorldWideWaitbecauseit_________beveryslow.
A.shouldB.mustC.willD.can
D在通常情况下,情态动词can表示推测时,只用于否定句和疑问句,不用于肯定句,但有一种特殊情况就是它可以用于肯定句中表理论上的推测或表示“有时”之意,而此题考查的正是can表示“有时”的用法。
8.ZhangLinwasaddictedtocomputergamesduringhislastyearinhighschool,otherwisehe____________astudentofBeijingUniversity.
A.wouldhavebeenB.shouldbeC.hasbeenD.hadbeen
Aotherwise引起虚拟语气的虚拟语气属于含蓄型的,由句意可以得知是与过去的事实相反,主句用wouldhavedone。
9.---Yoursisternearly_______allhersparetimetoherstudyduringthethreeyears.
----Thatsright,orshe________thefirstplaceinherschoolintheCollegeEntranceExamination.
A.devoted;wouldnthavetakenB.spent;wouldnthavetaken
C.haddevoted;hadnttakenD.hadspent;couldnttake
Adevote…to为固定搭配,因此第一个空应从AC选。Or翻译成“否则,要不然”,相当于otherwise,引起句子运用虚拟语气,主句用wouldhavedone。
10.—Anyinformationaboutyourson?
—No.IfonlyI______thosetoughwordstohim.
A.didntsayB.hadntsaid
C.shouldnthavesaidD.couldnthavesaid
Bifonly引起的句子要用虚拟语气。与wish跟从句用虚拟的规则一样。与过去的事实相反,用过去完成时态。
11.Itisvitalthatwe_____actoutatoncetoprotecttheenvironment.
A.wouldB.shouldC.willD.can
BItisvital/important/strange/necessary/natural…that从句中,从句运用should跟动词原形。
12.John’spalefacesuggestedthathe______ill,andhisparentssuggestedthathe______amedicalexamination.
A.be,shouldhaveB.was,haveC.shouldbe,hadD.was,has
Bsuggest表示“表明,暗示”时,宾语从句不用虚拟语气,而表示“建议”时,要用should跟动词原形的虚拟语气。根据句意可以得知,答案为B
13.ButfortheleadershipofourPartyandourGovernment,we__________thesesplendidresults.
A.haveachievedB.shouldn’thaveachieved
C.shouldhaveachievedD.wouldachieve
Bbutfor相当于without,可以用if非真实条件句替换。有句意可知时发生在过去,与过去事实相反。
14.--Wherehaveyoubeen?
--I_______intheheavytraffic.OtherwiseI______hereearlier.
A.gotstuck;wouldhavecomeB.gotstuck;was
C.havegotstuck;wouldhavecomeD.hadgotstuck;wouldcome
A由句意得知被交通堵塞困住是发生在过去,第一空用一般过去时,排除CD,第二空为与过去事实相反,故选A
15.Hehesitatedforamomentbeforekickingtheball,otherwisehe____agoal.
A.hadscoredB.scoredC.wouldscoreD.wouldhavescored
D这是otherwise引出的含蓄虚拟语气,再根据前面的hesitated可进一步知道这是与过去事实相反的虚拟语气.
考生在复习情态动词和虚拟语气时要注意如下几点:
1.掌握情态动词的基本用法;2.正确辨析相近意义的情态动词;3.把握常用情态动词句式;
4.学生要明确所叙述的内容不可能发生或发生的可能性很小时,要用虚拟语气;
5.把握虚拟语气的常用句式;6.正确辨析混合时间的虚拟语气,如果条件句中的动作和主句的动作不是同时发生,主句和从句的谓语动词的形式应分别根据各自所表示的时间加以调整。
7.注意虚拟语气中的倒装句,如果虚拟语气的条件从句谓语动词中含有were,had,should,有时可将if省去,而将条件从句的主语置于were,had,should,之后
8.分清含蓄条件句,有时为了表达的需要,在虚拟语气中不总是出现if引导的条件句,而通过用其他词来代替条件句,常见词有otherwise,or,butfor和ifonly等
9.掌握在表语从句,同位语从句和主语从句中,表示间接的命令、要求、请求、建议、决定等,主句的主语通常是suggestion,proposal,request,order,idea等。从句中的谓语动词是should+动词原型,should可以省略。
10.掌握口语中的虚拟语气和固定句式中的虚拟语气。

A.breaksB.hasbroken
C.werebrokenD.hadbeenbroken

参考答案和解析
1.Casif引导的句子,有时用虚拟语气,有时不用。原则上说,若指事实或可能为事实,不用虚拟语气;若指现在,从句谓语动词用一般过去时(be用were);若指过去用过去完成时,若指将来用过去将来时或用weretodosth.
2.Cbutfor的意思是“若不是,要不是”,用于引出与事实相反的假设,通常与虚拟语气连用。根据句中的thehelpyougaveme,可知它表示与过去事实相反,故选C.
3.B根据上文的语境可知句中的or隐含有一个虚拟的条件,即or=ifIdidn’tforgetwhereIreadthearticle(要是我没忘记我在哪儿读过这篇文章的话——但事实上忘了)。
4.D关键信息是Itlooksasifheweredrunk中的虚拟语气,句子既然用了虚拟语气,也就是说,“他喝醉了”不是事实,只是他的言行好像是醉了,所以此题的最佳答案是D.
5.D由于空格后的if条件状语从句的谓语用的是虚拟语气(这是很重要的信息),所以主句要用would而不用will,即答案应选D.
6.C按照英语习惯,wouldrather后接that从句时,从句谓语通常要用虚拟语气,即用过去式表示现在或将来,用过去完成时表示过去。
7.Dinsist后的从句谓语有时用“should+动词原形”这样的虚拟语气,有时不用,具体要看该谓语动词所表示的含义。一般说来,若该谓语动词所表示的动作尚未发生,或尚未成为事实,则用虚拟语气;若该谓语动词所表示的动作已经发生,或已经成为事实,则要用陈述语气。分析上题的句意,可知只有选D最合适。
8.B是因为时态前后有矛盾。由于主句谓语是wouldnothavegot,这表明是对过去事实作出的假设,所以从句谓语应该是hadgivenup,而不是像D项那样用一般过去时。另外,当虚拟条件句中有had,should,were等词时,通常可以省略if,并将had,should,were提前置于句首。
9.BIt’stimeyoudid为It’stimeyouthankedAuntLucyforherpresent之略。按照英语语法,it’stime后从句通常要用过去式。
10.B第一空填knew,因为Iwish后的宾语从句要用虚拟语气(即用过去式表示现在的想法);第二空要填lives,即用陈述语气,因为wherehelives是一个客观事实,而不是Iwish的内容。
11.B此题涉及错综时间虚拟条件句,主句与现在事实相反,条件句与过去事实相反。句意为:要不是在七岁时就迷上了MelindaCox图书馆,我真不能想像我如今会在做什么。
12.Awithout引出的介词短语为一个与现在事实相反的含蓄条件句。
13.Cifonly意为“,但愿,要是……就好了”,其后的句子谓语要用虚拟语气,用以表达愿望或非真实条件,同时根据句意可以得知从句是与过去事实相反
14.B本题考查虚拟语气和表语从句。在Itisnecessarythat…句型中,从句中常常用虚拟语气,其形式为“should+动词原型”,should也可以省略。第二空考查了表语从句。That没有实际的意义,只起一个连接的作用。
15.B考查虚拟语气。从主句的谓语动词及句意推测应选B。其他选项不符合题意。
16.B本题考查了虚拟语气的倒装。如果虚拟语气的条件从句谓语动词中含有were,had,should,有时可将if省去,而将条件从句的主语置于were,had,should之后。
17.C虽然前有虚拟条件句,后有使用了虚拟语气,但thefact不是与事实相反,而是现在的真实情况,故不用虚拟语气。
18.C,表示机器什么的不能工作了。是一种关于性能方面的,很固定的用法。
19.Ccannottoo...to是词组,意思是就算怎么样也不过分。
20.B可是根据句子的意思。musthavechosen是本来肯定会------,故答案为B。
