Don’ttouchanythingonthetableuntilthebellrings.一.語(yǔ)氣的分類虛擬語(yǔ)氣虛擬語(yǔ)氣是一種特殊的動(dòng)詞形式，一是用來表示說話人所說的話不是一個(gè)事實(shí)，而是一種假設(shè)、猜測(cè)、懷疑等(在條件從句中或讓步狀語(yǔ)從句中)；一是表示說話人的愿望、要求、命令、建議等(在賓語(yǔ)從句、主語(yǔ)從句、表語(yǔ)從句、同位語(yǔ)從句)。虛擬語(yǔ)氣的概念虛擬語(yǔ)氣一、在條件從句中(叫虛擬條件句)，表示與事實(shí)相反的條件。分三種情況(以do為例)：虛擬語(yǔ)氣在在條件從句中表示與事實(shí)情況相反條件從句的謂語(yǔ)形式主句的謂語(yǔ)形式表示現(xiàn)在情況過去式(did)(be常用were)Would/could/might/should(用于第1人稱)+動(dòng)詞原形(do)表示過去情況過去完成式(had+done)Would/could/might/should+havedone表示將來情況①過去式(did)/(were)②should+do③weretodoWould/could/might/should+do1.IfI

threedaysoff,wewouldenjoyaveryhappylife.(與將來事實(shí)相反)2、錯(cuò)綜時(shí)間的虛擬句通常情況下,在非真實(shí)條件句中主句和從句的謂語(yǔ)動(dòng)詞所指時(shí)間是一致的,但有時(shí)也可能指不同的時(shí)間,這時(shí)要根據(jù)上下文的意思采用不同的謂語(yǔ)動(dòng)詞形式.1.IfIwereyou,Iwouldhavetakenhisadvice.(從句指現(xiàn)在,主句指過去)。2.IfIhadtakenmyraincoatwithmethismorning,Iwouldnotbewetnow.(從句指過去,主句指現(xiàn)在)。3.Ifwehadn’tbeenworkinghardinthepastfewyears,thingswouldn’tbegoingsosmoothly.（從句指過去，主句指現(xiàn)在）。4.Iftheweatherhadbeenmorefavorable,thecropswouldbegrowingstillbetter.（從句指過去，主句指現(xiàn)在）。5.Ifwehadnotgoteverythingreadybynow,weshouldbehavingamoreterribletimetomorrow.（從句指現(xiàn)在，主句指將來）

3、含蓄條件句有時(shí)假設(shè)的情況并不以條件從句表示出來,二是暗含在上下文中,比如通過介詞短語(yǔ)來表示。這些介詞常是：butfor,without,otherwise等。如：

Butforyouradvice,Icouldnothavedoneitsosuccessfully.如果不是聽了你的建議，我就不會(huì)做的如此成功。Thechangecouldnothavetakenplacewithouttheopen-doorpolicy.沒有開放的政策，就不會(huì)有如此大的變化。Iwassobusythen,Otherwise,Iwouldhavetoldhimtheanswer.我當(dāng)時(shí)很忙，否則，我就會(huì)把答案告訴他的。虛擬語(yǔ)氣4、省略if的條件從句當(dāng)從句中有were,had

或should

時(shí)，可省略if，而把它們放在句首。IfIweretomeethimtomorrow,Ishouldaskhimaboutit.

WereItomeethimtomorrow,…Ifheshouldfailintheexperimentthistime,hewouldtryagain.Shouldhefailintheexperiment…

Ifyouhadcomeafewminutesearlier,youwouldhavemethim.虛擬語(yǔ)氣在在條件從句中Hadyoucomeafew….5.Ifonly…要是就好了

名詞性從句的虛擬語(yǔ)氣。主要是表示命令、要求、建議的虛擬語(yǔ)氣。賓語(yǔ)從句。常見動(dòng)詞：一個(gè)堅(jiān)持：insist兩個(gè)命令：order,command

三個(gè)建議：advise,suggest,propose五個(gè)要求：demand,require,request,desireask

這些動(dòng)詞后面的賓語(yǔ)從句要使用虛擬語(yǔ)氣用法。即從句中的動(dòng)詞使用should+動(dòng)詞原形，或者將should省略。我們建議Tom去休息一下。他堅(jiān)決要求我到場(chǎng)。國(guó)王命令囚犯明天要實(shí)施死刑。他們要求我們派他們?nèi)ツ莾汗ぷ?。WesuggestedthatTom

(should)send

themtoworkthere.虛擬語(yǔ)氣在：在賓語(yǔ)從句中

注意:insist/suggest各有兩意思，要用不同的語(yǔ)氣①表“堅(jiān)決要求”,虛擬,should+do;②表“堅(jiān)稱,堅(jiān)持說”,陳述語(yǔ)氣,表事實(shí)。①表“建議”，虛擬,should+do;②表“表明、暗示”，用陳述語(yǔ)氣。Theteachersuggestedthatwe______________moreafterclass.（我們課后多練習(xí)）Thelookonherfacesuggestedthatshe________happyHeinsistedthatallofus___________thereontimebyanymeans.（我們大家想盡辦法按時(shí)去那兒）Heinsistedthathe_____________thewallet(沒有偷錢包).insistsuggest(should)practisewasshouldbedidn’tsteal

以上動(dòng)詞相應(yīng)的名詞構(gòu)成的名詞性從句包括主語(yǔ)從句，表語(yǔ)從句和同位語(yǔ)從句也要使用虛擬語(yǔ)氣。從句中的動(dòng)詞形式一樣。即：(should)＋V.

的賓語(yǔ)從句現(xiàn)在：過去：將來：過去時(shí)（were）過去完成時(shí)would/could/might+V.shouldIwishIwereabird.（現(xiàn)在）IwishIhadn’tmadesuchamistake.（過去）Wewishourparentswouldn’tpunishus.

（將來）asif,asthough引起的從句，其用法同wish構(gòu)成的賓語(yǔ)從句一樣Asif/though和wish用法相同Helooksasifheweredrunk.Theytalkedasiftheyhadbeenfriendsforyears.Shelovesthebabyasifitwereherownson.Itseemsasifitwerespring.Irememberedthewholethingasifithadhappenedyesterday.2.wouldrather(that)現(xiàn)在：過去：將來：Iwouldratheryoupaidmenow.

Iwouldratheryouhadgone,too.Don’tcome.Iwouldratheryoucame

tomorrow.過去時(shí)過去時(shí)過去完成時(shí)3.It’s(about/high)time+(that)…should+V.過去時(shí)你該走了。我們?cè)撊ニX了。It’shightimethatyouwent.It’shightimethatyouweregoing.It’shightimethatyoushouldgo.It’stimethatwewenttobed.It’stimethatweshouldgotobed.(Should不可省略)4.
