Don’ttouchanythingonthetableuntilthebellrings.一.语气的分类虚拟语气虚拟语气是一种特殊的动词形式，一是用来表示说话人所说的话不是一个事实，而是一种假设、猜测、怀疑等(在条件从句中或让步状语从句中)；一是表示说话人的愿望、要求、命令、建议等(在宾语从句、主语从句、表语从句、同位语从句)。虚拟语气的概念虚拟语气一、在条件从句中(叫虚拟条件句)，表示与事实相反的条件。分三种情况(以do为例)：虚拟语气在在条件从句中表示与事实情况相反条件从句的谓语形式主句的谓语形式表示现在情况过去式(did)(be常用were)Would/could/might/should(用于第1人称)+动词原形(do)表示过去情况过去完成式(had+done)Would/could/might/should+havedone表示将来情况①过去式(did)/(were)②should+do③weretodoWould/could/might/should+do1.IfI

3、含蓄条件句有时假设的情况并不以条件从句表示出来,二是暗含在上下文中,比如通过介词短语来表示。这些介词常是：butfor,without,otherwise等。如：

Butforyouradvice,Icouldnothavedoneitsosuccessfully.如果不是听了你的建议，我就不会做的如此成功。Thechangecouldnothavetakenplacewithouttheopen-doorpolicy.没有开放的政策，就不会有如此大的变化。Iwassobusythen,Otherwise,Iwouldhavetoldhimtheanswer.我当时很忙，否则，我就会把答案告诉他的。虚拟语气4、省略if的条件从句当从句中有were,had

或should

时，可省略if，而把它们放在句首。IfIweretomeethimtomorrow,Ishouldaskhimaboutit.

WereItomeethimtomorrow,…Ifheshouldfailintheexperimentthistime,hewouldtryagain.Shouldhefailintheexperiment…

Ifyouhadcomeafewminutesearlier,youwouldhavemethim.虚拟语气在在条件从句中Hadyoucomeafew….5.Ifonly…要是就好了

名词性从句的虚拟语气。主要是表示命令、要求、建议的虚拟语气。宾语从句。常见动词：一个坚持：insist两个命令：order,command

三个建议：advise,suggest,propose五个要求：demand,require,request,desireask

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。我们建议Tom去休息一下。他坚决要求我到场。国王命令囚犯明天要实施死刑。他们要求我们派他们去那儿工作。WesuggestedthatTom

arest.HeinsistedthatI

(should)be

present.Thekingorderedthattheprisoners

thenextday.Theyrequestedthatwe

(should)send

themtoworkthere.虚拟语气在：在宾语从句中

注意:insist/suggest各有两意思，要用不同的语气①表“坚决要求”,虚拟,should+do;②表“坚称,坚持说”,陈述语气,表事实。①表“建议”，虚拟,should+do;②表“表明、暗示”，用陈述语气。Theteachersuggestedthatwe______________moreafterclass.（我们课后多练习）Thelookonherfacesuggestedthatshe________happyHeinsistedthatallofus___________thereontimebyanymeans.（我们大家想尽办法按时去那儿）Heinsistedthathe_____________thewallet(没有偷钱包).insistsuggest(should)practisewasshouldbedidn’tsteal

以上动词相应的名词构成的名词性从句包括主语从句，表语从句和同位语从句也要使用虚拟语气。从句中的动词形式一样。即：(should)＋V.

（将来）asif,asthough引起的从句，其用法同wish构成的宾语从句一样Asif/though和wish用法相同Helooksasifheweredrunk.Theytalkedasiftheyhadbeenfriendsforyears.Shelovesthebabyasifitwereherownson.Itseemsasifitwerespring.Irememberedthewholethingasifithadhappenedyesterday.2.wouldrather(that)现在：过去：将来：Iwouldratheryoupaidmenow.
