——使表达更优雅得体高考英语二轮复习专题九【考纲解读】

虚拟语气是高考热点，考生需要注意if条件从句中虚拟语气的用法、含蓄条件句中虚拟语气的用法和名词性从句中虚拟语气的用法以及虚拟语气中倒装的出现等。高考还将加大对虚拟语气的考查。虚拟语气表示说话人的愿望、假设、猜测或建议，而不表示客观存在的事实。虚拟语气通过谓语动词的特殊形式来表示。

一“表”

1.Ifyouhadtakenmyadvice,youwouldn’thavefailedintheexam.

——Hadyoutakenmyadvice,youwouldn’thavefailedintheexam.2.Ifhewereintheroomnow,hewouldn’tfeelsocold.——Wereheintheroomnow,hewouldn’tfeelsocold.3.IfI

shouldhavetime,Iwouldgowithyou.——ShouldIhavetime,Iwouldgowithyou.(省if)倒装条件句Step1、观察思考。小结当条件句中有______，___________或______时，可省略_____,把这三个词提到句首。Eg:IfIwere

notsobusy,Iwouldgowithyou.werehad(助动词)shouldif注意：若条件从句为否定句，否定词应位于主语之后。WereInotsobusy,Iwouldgowithyou.Step2、运用规律（将以下句子改为省略if的倒装条件句）

IfIwereatschoolagain,Iwouldstudyharder.——______________________________________Ifyouhadcomeearlier,youwouldcatchthebus.——_______________________________________IfIwerenottohaveatest,Iwouldgototheconcerttonight.——______________________________________________WereIatschoolagain,Iwouldstudyharder.

Hadyoucomeearlier,youwouldcatchthebus.WereInottohaveatest,Iwouldgototheconcerttonight.含蓄条件句：

Butforyourhelp,wecouldn’thavesucceeded.

Without

air,we

wouldnotlive

evenforfiveminutes.

以上句子中虚拟条件没有使用从句，而是通过_____短语来表示，这种句子叫做___________。这种句子往往是有主句而无从句。可用于这种句式的介词或连词________/_________/or/_________等。含蓄条件句butforwithoutotherwise做题关键：通过句意判断准对什么时间的虚拟，然后选择出正确的动词形式。介词二“混”一.混时态:二.混虚实:时间错综的虚拟语气Ifyouhad

takenthemedicinelastnight,youwouldbebetternow.Ifyouhadtakenthemedicinelastnight,youwouldbebetternow,butyoudidn’t.————————虚实If从句中时间与主句时间不一致。虚实错综的虚拟语气

三“从句”1：虚拟语气在名词性从句中用法

关键词★一坚持；二命令；三建议；

四要求

★

(should)do2:Itis+adj/n/v-ed+that…(should)do…

关键词important/necessary/natural/strange/apity/ashame/suggested3:虚拟在特殊句型中的用法

关键词：◆wish,asif/though,ifonly,wouldrather

表示要求，命令，建议等动词后的宾语从句。一个坚持：insist两个命令：order,command

三个建议：advise,suggest,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，或者将should省略。注意insistsuggestMysuggestionisthatyou(should)gohomefirstbeforecominghere.Theordercamethatthework(should)befinishedtwodaysaheadoftime…

“三反”“两反”5.It’s(about/high)time+(that)should+V.过去时你该走了。我们该去睡觉了。It’shightimethatyouwent.It’shightimethatyoushouldgo.It’stimethatwewenttobed.It’stimethatweshouldgotobed.(Should不可省)学法建议

在学习if引起的虚拟条件句时，同学们首先要牢记它的三种形式，它将为学习此类句子奠定基础，在此基础上，才能掌握倒装的虚拟条件句及混合虚拟条

件句等。综观历年的高考题及各地测试题，wish引导的宾语从句的虚拟语气及if引导的虚拟条件及含蓄条件句是考试的重点，务必请同学们在学习中加以注意。在学习asif引导的表语从句或状语从句中的虚拟语气时
