虚拟语气-公开课-精品-全课件

语气英语的动词一般可带有三种不同的语气：陈述语气，祈使语气和虚拟语气。不同的语气用动词的不同形式（有的还借助句法形式）来表示。1、If+主语+动词过去式2、If+主语+wereto+动词原形3、If+主语+should+动词原形If+主语+动词的过去式（be动词一般用were)主语+would(should/might/could)＋动词原形即：If+一般过去时态（be动词一般用were)If+主语+had+动词的过去分词即：If+过去完成时态主语+would(should/might/could)＋havedone主语+would(should/might/could)＋动词原形SubjectivemoodIf型Should+v型类似if型。。。。。。。。。混杂条件句(各自为准)Were,had,should提前，省略if1.一个坚持，两个命令，三个建议，四个要求。2.Itis（necessary，strange…）+that…wish/asifWouldrather/ifonlyItis(high)timethat…Butfor/otherwise/without/inthatcase1.过去式2.过去完成3.could、would、might+v1.过去式2.过去完成Should（不省）+v/过去式1.Would,could,should,might+v2.would,could,should,might+havedoneinsistsuggestIfIhadgotupearlier

两个命令：order,command

三个建议：suggest,advise,propose

四个要求：demand,require,request,desire这些动词后面的宾语从句要使用虚拟语气用法。即从句中的动词使用should+动词原形，should可省略。

that…(should)do…Isuggestthatwe(should)holdameetingnextweek.Heinsistedthathe(should)besentthere.注意：如suggest,insist不表示"建议"或"坚持要某人做某事时"，即它们用于其本意"暗示、表明"、"坚持认为"时，宾语从句用陈述语气。1.Theguardatthegateinsistedthateverybody____(obey)therules.2.Heinsistedthatshe______(be)seriouslyillandthat_________(send)tohospitalsatonce.3.Hesuggestedthatwe________(have)ameetingatonce.4.Hispalefacesuggestedthathe______(be)ill.obeywasbesenthavewas例(2010·福建，29)Teachersrecommendparents________theirchildrenunder12toridebicyclestoschoolforsafety.A．notallowB．donotallowC．mustn'tallowD．couldn'tallow解析：考查虚拟语气。recommend后的宾语从句谓语动词用“(should)＋动词原形”，因此A项正确。答案：AIt’ssuggestedthattheplan

过去完成时Ifonly例(2010·东北三校联考)—Whydoyoulooksoupset?—Ibrokeupwithmygirlfriend.IfonlyI________moreabouther.A．care B．caredC．hadcared D．hadbeencared解析：考查虚拟语气。ifonly表示“要是……就好了”，后面的句子要用虚拟语气。表示与过去事实相反的情况时，谓语动词用haddone的形式。答案：C5.evenif(eventhough)即使,尽管

Evenifhewerehere,hecouldnotsolvetheproblem.EvenifIhadbeenbusythen,Iwouldhavehelpedyou.6、incase,forfearthat,lest等引导的状语从句中的虚拟语气

在incase,forfearthat,lest等引导的目的状语从句中,谓语动词用“should+动词原形”的形式,也可用动词的一般现在式或一般过去式。Hehandledtheinstrumentwithcareforfearthatitshouldbedamaged.

他小心地拿着仪器,生怕把它摔碎了。总结wish,wouldrather,asif/asthough,ifonly表虚拟时的共同点是：时态往后退一步，同if虚拟条件句四.情态动词表示虚拟
