beamanfromAmerica,isn'the？Hemustbetalkingwithhisfriend,isn'the？Hemusthavealreadyarrivedthere,hasn't/didn'the？Youmothermusthavebeentoldaboutthetruthjustnow,wasn'tshe？2may和might意为“也许”，后者语气弱，更没有把握，可用于肯定句和否定句Hemaynotbeathome.Theymighthavefinishedtheirtask.3can和could意为“可能”，could表示可疑的可能性，不及can语气强，用于肯定句、否定句、疑问句中Theweatherinthatcitycouldbecoldnow.Wecouldhavewalkedthere;itwassonear.—Canhebeintheofficenow？—No,hecan'tbethere,forIsawhiminthelibraryjustnow.要点储备三：情态动词＋havedone用法例句表推测时(陈述)：may/mighthavedonesth.(语气不肯定)过去可能做了某事can't/couldn'thavedonesth.(语气肯定)过去不可能做了某事musthavedonesth.(语气肯定)过去一定做了某事shouldhavedonesth.应该已做完某事；竟然做了某事(表惊讶)oughttohavedonesth.应该已做完某事Ididn'tseeMaryatthemeetingyesterday.—Shemighthavebeenill,Iguess.Thestreetsarealldry.Itcouldn'thaverainedduringthenight.Thestreetsareallwet;itmusthaverainedduringthenight.Ihardlyimaginesuchagentlemanshouldhavebeensorudetotheoldlady.TheyshouldhavearrivedinBeijingbythistime.表责备时(虚拟)：mighthavedonesth.过去本可能做而未做couldhavedonesth.过去本能做而未做shouldhavedonesth.过去本该做而未做oughttohavedonesth.过去本应该做而未做区别：needn'thavedonesth.过去本不必做却做了didn'tneedtodosth.＝Itwasn'tnecessarytodosth.Hemighthavegivenyoumorehelp,evenifhewasverybusy.—Didyoulistentothespeech？—No,wecouldhaveattendedit.Butwehadalotoftrafficonourway.Yourbrother'sfailedinEnglishagain.Yououghtto/shouldhavegivenhimmorehelp.—Mr.Smithdidn'tcomelastnight,didhe？—No.Weneedn'thavewaitedforhim.Awholenightwaswasted.—Sorry,sir.Ididn'tattendyesterday'smeeting.—Youdidn'tneedtocome.Actually,themeetingwascancelled.-10-\n表意愿时(虚拟)：wouldhavedonesth.想做而未做，本可以做而未做某事wouldliketohavedonesth.想做而未做某事wouldratherhavedonesth.宁愿做某事而未做某事Iwouldliketohavegonetoyourhelp,butIwastoobusy.Thefilmwasabore.Iwouldratherhavestayedathome.表未曾实现的希望，打算、意图、诺言等：hadhoped/planned/...＋todo＝hoped/planned/...＋tohavedone＝should/wouldliketohavedone＝would(rather)havedone＝was/weretohavedonewasgoingto...本打算……Ifyouhadcomefiveminutesearlier,youwouldhaveseenthefamousstar.Iwastohavecomeyesterday,butmymotherfellill.＝Ihadwantedtocomeyesterday,butmymotherfellill.＝Iwantedtohavecomeyesterday,butmymotherfellill.＝Iwouldliketohavecomeyesterday,butmymotherfellill.＝Iwouldhavecomeyesterday,butmymotherfellill.要点储备四：虚拟语气类别用法例句if引导的条件从句与现在事实相反从句谓语：过去式(be用were)主句谓语：should/would/could/might＋动词原形Ifhewerehere,hewouldhelpus.与过去事实相反从句谓语：had＋过去分词主句谓语：should/would/could/might＋have＋过去分词IfIhadbeenfree,Iwouldhavevisitedyou.与将来事实相反从句谓语：过去式/should＋动词原形/were＋不定式主句谓语：should/would/could/might＋动词原形Ifitshouldraintomorrow,wewouldnotgocamping.if条件句的倒装省略如从句中含有had,were,should时，可把该词移至从句句首，同时省略ifIfIwereyou＝WereIyou,Iwouldtakethejob.错综虚拟如主从句中使用不同的时间状语，主从句的虚拟则要依据各自时间状语IfIhadstudiedmedicineincollege,Icouldhelpyounow.(should)＋dosth.类宾语从句advise，suggest,recommend,ask,demand,require,request,order,command,decide,insist,urge后接的宾语从句中谓语动词为should＋动词原形，should可省略区别：Hesuggestedthatwenotchangeourmind.Hispalefacesuggestedthathewasill.Heinsistedhehaddonenothingwrongandthathe(should)besetfreeatonce.-10-\n主语从句Itisnecessary/important/strange/natural/amazing＋that从句Itissuggested/demanded/ordered/requested/arranged/decided＋that从句Itisapity/ashame/nowonder＋that从句(that从句中谓语为“should＋动词原形”，should可省略)Itisstrangethatsuchapersonshouldbeourfriends.It'sapitythatwemissedsuchagoldenchance.It'sdemandedthathe(should)goatonce.表语从句主语是idea,suggestion,order,request,decision,urge等，其后的表语从句中谓语为“should＋动词原形”，should可省略Mysuggestionisthatheshouldbeoperatedonatonce.Theirdecisionisthattheybuyit.同位语从句以urge,idea,suggestion,order,request,decision等为先行词的同位语从句中，谓语为should＋动词原形，should可省略Imadeasuggestionthatheshouldbeoperatedonatonce.ThesuggestionImadeatthemeetingwasturneddown.wish类wish从句＝Ifonly从句一般过去时(对现在虚拟)过去完成时/couldhavedone(对过去虚拟)could/might/would＋dosth.(对将来虚拟)IwishIcouldbeapopsinger.Iwishhehadvisitedusthen.＝Ifonlyhehadvisitedusthen.“情态动词＋have(been)done”表对过去的虚拟详见要点储备三常见结构主语＋would/could/might/...havedone,but＋主语＋过去时；主语＋过去时，otherwise＋主语＋would/could/might/...havedonebutforsth.＝butthat＋主语＋过去时＝without＋n.＝ifithadnotbeenfor...,主语＋would/could/might/...havedone主语＋hadwanted/meant/intended/hoped/...,but＋主语＋过去时Iwouldhavegonetohelpyou,butIwastoobusy.＝Iwastoobusy,otherwiseIwouldhavegonetohelpyou.Butfortherain,Iwouldhavegonetothecinema.-10-\n状语从句asif引导的状语从句中谓语用过去式或过去完成式Theyaretalkingasiftheyhadbeenfriendsforyears.inorderthat/sothat引导的目的状语从句中谓语用“can/could/may/might/would/...＋动词原形”Turnonthelightsothatwecanseeitclearly.其他句型中Itis(high/about)time＋that从句中谓语用过去式或“should＋动词原形”It'shightimethatweleft.wouldrather所接的从句中谓语用过去式或者过去完成式分别表对现在将来或对过去的虚拟Iwouldratheryoustayedathomenow.表祝愿Longlive＋主语！May＋主语＋动词原形！LonglivethePeople'sRepublicofChina！Mayyoubehappy！重点突破近两年考查情态动词和虚拟语气的频率基本稳定，但试题中的有效信息越来越隐蔽，情景越来越生动真实，考查的角度越来越细微。除了从整体上把握情态动词的语法特征和语义特征外，能够准确理解不同情态动词的细微差异，认真区别具有相同功能的、意思相近的情态动词的用法并在真实的交际情景中印证和领悟情态动词的用法和特征显得尤为重要。1.You________worryaboutmystudies—Iknowquiteclearlywhattodoatschool.A.shouldn't　B.mustn'tC.needn't　D.can't2.Itisrequiredbylawthatenoughevidence________toproveoneisinnocentofacrime.A.isprovided　B.hasbeenprovidedC.beprovided　D.havebeenprovided3.Beingconstantlyexposedtoadvertisementsisannoying,butit________bepleasant
