实用标准文案专题七　情态动词和虚拟语气常考点近两年考查情态动词和虚拟语气的频率呈上升趋势。从整体上把握情态动词的语法特征和语义特征，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、意思相近的情态动词的用法，在真实的交际情景中印证和领悟情态动词的用法和特征。　　情态动词所表示的多种含义1.can和could的用法①表示能力。如：Icanrunfast.②表示客观可能性。如：Anexperienceddrivercanhaveanaccidentattimes.③表示请求和允许。用could语气更委婉。如：—Can/CouldIgonow?—Yes，youcan.④表示猜测、惊异、怀疑、不相信的态度(主要用于否定句、疑问句或惊叹句中)。如：Canthisbetrue?Howcanyoubesocareless!Thiscannotbedonebyhim.2.may和might的用法①表示许可。如：Youmaydrivethecar.—May/MightIuseyourpen?—No，youmustn"t.②用于祈使句中表示祝愿。如：Mayyousucceed!③表示推测、可能(疑问句不能用于此意)。表推测的might并不是指过去时间，而表示比may把握性略小些。如：Hemaybeverybusynow.④用于表示目的或让步状语从句中。如：Nomatterwhatdifficultiesyoumaycomeacross，youshouldn"tgiveup.3.will和would的用法①用于各种人称，表示“意志”“意愿”“决心”等。如：Itoldhertostopcrying，butshejustwouldnotlisten.②用于第二人称的疑问句，表示说话人向对方提出请求。用would比用will语气更客气。如：Will/Wouldyoupleasekeepthedooropen?③表示真理或习惯，意为“惯于，总是”。如：Shewilllistentomusicaloneinherroomforhours.Hewouldgetupearlywhenhelivedinthecountry.4.should的用法文档大全 实用标准文案①表示现在或将来的责任或义务，意为“应该，应当”，这时它可以和oughtto，besupposedto互换使用。如：Youshould(＝aresupposedto)completeyourtestintime.②表示有较大可能实现的猜测、推论，通常意为“可能；总该……吧”，相当于beexpectedto。如：Theyshouldbehomebynow，Ithink.③用于第一人称时可以表示说话人的一种谦逊、客气、委婉的语气。如：Ishouldthinkitwouldbebettertotryitagain.④用在条件状语从句中，表示语气较强的假设，意为“万一”，这时也可将should置于从句之首，即将should放在主语前面，而省略从属连词if，主句谓语却不一定用虚拟语气。如：ShouldI(＝IfIshould)befreetomorrowIwillcome.⑤用来表示意外、惊喜或者在说话人看来是不可思议的。尤其在以why，who，how等开头的修辞疑问句或某些感叹句中常常意为“竟会，居然”。如：Agentlemanlikehimshouldberudetoalady!⑥用于虚拟语气句中(略)。5.oughtto的用法表示应该、推测，相当于should。如：Yououghttotakecareofhim.6.shall的用法①用于第二、三人称，表示说话人的意愿，有“命令”“警告，威胁，强制”“法令条文规则”和“允诺”等意思。如：YoushallhavethebookwhenIfinishreading.(表允诺)②在疑问句中，shall用于征求对方的意见或请求指示，常用于第一、第三人称。如：Shallwegooutforawalk?Whereshallhewaitforus?7.must的用法①表示义务、意图或建议，意为“必须，应该，禁止(用于否定句中)”。如：Youmustgoandseethatfilm—you"dreallyenjoyit.②表示推测，意为“必定，一定”。[注]must表示推测时的否定式是can"t或couldn"t(不可能)。　③表示主张，意为“硬要，一定要”。如：Ifyoumustgo，atleastwaittilltherainstops.④表示与说话人愿望相反，意为“偏要”。如：Themachinemustbreakdownatthisbusyhour.8.need和dare的用法①need作“必要”讲时，既可作情态动词，也可作实义动词。作实义动词时后面的动词不定式要带to，其变化与一般动词相同。作情态动词时，仅用于否定句或疑问句中。②dare作为情态动词时，仅用在疑问句、否定句和条件从句中。dare若作实义动词，后面可接带to的不定式，此时to也可以省略。dare与need的用法相似。如：Hedarestogotherealone.Heneedstogotherealone.Shedoesn"tdare(to)askherfather.Shedoesn"tneedtoaskherfather.文档大全 实用标准文案Hedaren"tspeakEnglishbeforesuchacrowd，darehe?9.usedto的用法usedto表示过去的习惯动作或状态，现在已不存在，在间接引语中，其形式可不变。在疑问句、否定句、否定疑问句或强调句中，可有两种形式。疑问句·Didyouusetogotothesameschoolasyourbrother?·Usedyoutogotothesameschoolasyourbrother？否定句·Iusedn"ttogothere.·Ididn"tusetogothere.否定疑问句·Usen"tyoutobeinterestedinthetheatre?·Didn"tyouusetobeinterestedinthetheatre？其反意疑问句或简略回答中，也有两种形式：Sheusedtobeveryfat，didn"tshe？(正式)/use(d)n"tshe?(口语)—Usedyoutogetupearlyinthemorning?—Yes，Idid(正式)．/Yes，Iusedto.(口语)10.wouldrather(not)do　宁愿(不)做11.hadbetter(not)do　最好(不)做①I________oftengofishingwhenIlivedinthecountryside.A.shouldB.wouldC.couldD.might②I"vedecidedtotakethejobandI________changemymind.A.mustn"tB.can"tC.won"tD.maynot③“Whateveryouwant，you________haveitonconditionthatyougetthebestresult，”saidtheboss.A.wouldB.oughttoC.shallD.could④—Why________youstayinthecountryside，whereit"snotconvenienttogoshopping?—ButI"vefounditrathervaluableformyhealth.A.canB.mustC.mayD.shall⑤—Ipromiseherdaughter________getanicepresentonherbirthday.—Willitbeabigsurprisetoher?A.shouldB.mustC.wouldD.shall⑥Shejustcouldn"tbelievethatherhusband，towhomshehadbeenloyalforsomanyyears，________desertherafterhebecamerich.A.mightB.shouldC.shallD.must⑦—AMr.Smithiswaitingoutsidefortheappointmentwithyou.________hecomein?—Yes，pleaselethimin.文档大全
