2011高考英语备考（考点聚焦+名题导解）虚拟语气一、考点聚焦1、虚拟语气用于条件状语从句中（1）表示与现在事实相反的假设，条件状语从句中的谓语动词用“过去式（be动词的过去式用were）”，而主句中的谓语动词用“would/should/could/might+动词原形”。如：IfIwer 条件状语从句 主句 与过去事实相反 had+过去分词 should/would/could/might+have+过去分词 与现在事实相反 一般过去时(be用were) would/should/could/might+动词原形 与将来事实相反 一般过去时或should(wereto)+动词原形 Would/should/cold/might+动词原形有时侯在使用时可省略if,句子则可换成下列形式，即“were/had/should+主语”。如：WereIaboy,Iwouldjointhearmy.Hadhetakenmyadvice,hewouldhavesucceeded.Wereitnotfortheexpense,IwouldgotoBritain.[ks5u.comKS5U.COM]2、虚拟语气用于名词性从句（1）虚拟语气在宾语从句中的运用。①“wish+宾语从句”表示不能实现的愿望，译为“要是……就好了”等。表示现在不能实现的愿望，从句中的谓语动词用一般过去时；表示将来不能实现的愿望，从句中的谓语动词用“would/could+动词原形”；表示过去不能实现的愿望，从句中的谓语动词用“had+过去分词”或“could(should)+have+过去分词”。如： Iwishitwerespringalltheyearround. IwishIhadknowntheanswer. IwishIcouldflylikeabird. ②在表示建议、要求、命令等的动词suggest、advise、propose、demand、require、insistrequest、command、order等后的宾语从句中，谓语动词用should+动词原形或是动词原形。如： Shesuggestedwe(should)leavehereatonce. Thedoctororderedsheshouldbeoperated. （2）虚拟语气在同位语从句和表语从句中的运用。 作表示建议、要求、命令等的名词advise、idea、order、demand、plan、proposal、suggestion、request等的表语从句和同位语从句，从句中的谓语动词用“（should）+动词原形”。如： Hissuggestionthatwe(should)gotoShanghaiiswonderful. Myideaisthatthey(should)pay100dollars. （3）虚拟语气在主语从句中的运用。 在主语从句中，谓语动词的虚拟语气用“should+动词原形”的结构，表示惊奇、不相信、理应如此等。如： Itisnecessary(important,natural,strange,etc.)thatweshouldcleantheroomeveryday. Itwasapity(ashame,nowonder,etc.)thatyoushouldbesocareless. Itwillbedesired(suggested,decided,ordered,requested,proposed,etc.)thatsheshouldfinishherhomeworkthisafternoon. 注意：这种从句表示的是事实。如果说人对这种事实表现出惊奇的情感，就可用虚拟语气。反之，如果不表示惊奇等情感，that从句也可用陈述句语气。如： Itispitythatyoucan’tswim. 3、虚拟语气在其他场合的运用 （1）虚拟语气在asif/asthough、evenif/eventhough等引导的表语从句或状语从句中，如果从句表示的动作发生在过去，用过去完成时；指现在状况，则用一般过去时；指将来状况则用过去将来时。如： Hediditasifhewereanexpert. Evenifshewerehere,shecouldnotsolvetheproblem. （2）虚拟语气用于定语从句中。 这种从句常用于句型“Itis(high)time(that)…”中，定语从句的谓语动词用一般过去时(be用were)或should+动词原形，意思是“(现在)该……”。如： It’stimethatIpickedupmydaughter. It’shightimeweweregoing. （3）虚拟语气用在ifonly引导的感叹句中。如： IfonlyIwereabird. IfonlyIhadtakenhisadvice. （4）虚拟语气在一些简单句中的运用。 ①情态动词的过去式用于现在时态时，表示说话人谦虚、客气、有礼貌或语气委婉，常出现在日常会话中。如： Itwouldbebetterforyounottostayuptoolate. Wouldyoubekindenoughtoclosethedoor? ②用于一些习惯表达法中。如： Wouldyoulikeacupoftea? Iwouldrathernottellyou.L二、精典名题导解选择填空1.Whenapencilispartlyinaglassofwater,itlooksasifit_______.A.breaksB.hasbrokenC.werebrokenD.hadbeenbroken解析：答案为C。本题考查的是asif引导的让步状语从句中的语气问题，asif引导的状语从句如果与事实一致，不用虚拟语气，如果与事实相反，应用虚拟语气。题中“当铅笔的一部分浸在水中，铅笔看上去好像断了”。而实际上铅笔并未断，与事实相反，前半部分陈述是一般现在时，因而本句是对一般现在时的虚拟，用werebroken。2.Ididn’tseeyoursisteratthemeeting.Ifshe___________,shewouldhavemetmybrother.A.hascomeB.didcomeC.cameD.hadcome解析：答案为D。本题考查的是if条件句中的虚拟语气。题意是：我在会议上没看到你姐姐，故你姐姐没来。因此如果“她来了”与事实相反，前面一句交代了虚拟语气的时态是一般过去时的虚拟，所以if从句中用had+过去分词。3.—Ifhe___________,he________thatfood.—Luckilyhewassenttothehospitalimmediately.A.waswarned;wouldnottakeB.hadbeenwarned;wouldnothavetakenC.wouldbewarned;hadnottakenD.wouldhavebeenwarned;hadnottaken解析：答案为B。本题考查的是条件状语从句与主句表示与事实相反时虚拟语气的用法。根据下一句语境可知，他事先并没有得到警告，表示过去时间的虚拟语气，故选B。4.Mr.Whiteat8:30forthemeeting,buthedidn’tshowup.A.shouldhavearrivedB.shouldarriveC.shouldhavehadarrivedD.shouldbearriving解析：答案为A。本题考虚拟语气及责备的用法，全句意为：Mr.white8:30（原本）应该到会的，但他没露面。全句谈的是过去的事，故应使用shouldhavedone结构，表原本该做而没做的事。5.—I’lltellMaryabouthernewjobtomorrow.—Youherlastweek.A.oughttotellB.wouldhavetoldC.musttellD.shouldhavetold解析：答案为D。本题考查情态动词用法，should（oughtto）havedone表示说话人对发生的事性“责备”故选D。6.—Let’sgoandhaveagooddrinktonight.—Haveyougotthefirstprizeinthecompetition?A.Whatfor?B.Thanksalot.C.Yes,I’dliketo.D.Whynot?解析：答案为A。考语境及交际用语。前句建议：今晚咱们出去好好喝一顿吧。喝一顿应有个来由和原因，且多是为了庆祝某事，所以后句问：为何事（庆祝）？你是不是在竞赛中得了一等奖？这样才能表示后者惊讶、疑问和兴奋，whatfor：为何而做某事？其余均不合语境。 精选阅读 情态动词和虚拟语气 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) 虚拟语气 1.虚拟语气在条件句中的用法现在事实相反的假设 虚拟语气精练60题 一名优秀的教师在每次教学前有自己的事先计划，准备好一份优秀的教案往往是必不可少的。教案可以让学生能够在课堂积极的参与互动，帮助教师能够井然有序的进行教学。那么怎么才能写出优秀的教案呢？以下是小编为大家收集的“高考英语难点37讲--难点22虚拟语气”欢迎大家与身边的朋友分享吧！ 高考英语难点37讲--难点22虚拟语气 虚拟语气专练高考英语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
①时间错综虚拟结构
②省略if的虚拟结构
③并列连词或副词暗示的虚拟结构
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)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。

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

省去了"Ifyouhadwantedto")(事实是:你自己没洗衣服，因为你不想洗。)

命题意图：此题旨在考查wish后加宾语从句表示可实现的愿望。此题属四星级题。
知识依托：wish+宾语从句表示不可实现的愿望，译为“……就好了，但愿……”

解题方法与技巧：看whenapencilisputin…中谓语时态。
答案:C
●锦囊妙计
做好虚拟语气，除了掌握基本的结构外，还要注意句子所表达的意义与现在过去，还是将来事实相反，看清时间状语，另外还要注意在其他结构中虚拟语气的运用。
1.在主语从句中谓语动词的虚拟语气结构为：“should+动词原形”表示惊奇，不相信，惋惜等。
例：Itisadvisable/important/natural/necessarythatsb.(should)do
2.在Itistime/hightimethatsb.shoulddosth.
或Itistimethatsb.didsth
3.wouldrathersb.+过去时，指现在或将来。
例：I’dratherFatherwereherenow.
I’drathertheycameheretomorrow.
4.Butfor…without短语译为“要不是……”，句子谓语也常用虚拟。
