虛擬語氣總結版I.動詞的語氣簡介：

語氣——表示說話人對說話內容的看法的一種語法范疇。在英語中，可用不同的動詞形式表示說話的語氣。動詞的三種語氣：1、陳述語氣——所表達的動作或狀態(tài)是符合客觀現實的。

e.g.Flowersblossominspring.Heplayedthepianowell.2、祈使語氣——表示號召、命令、請求、勸告等。

e.g.Letushelpyou.Keepoffthegrass.3、虛擬語氣——與事實相反，表達的是假設，愿望，懷疑或推測等。II.虛擬語氣的運用

1）if真實條件句

2）if虛擬條件句

3）錯綜條件句

4）省略if的倒裝句

5）含蓄條件句（without，with,butfor,otherwise等后）

一、在if條件從句中的運用

二、其他形式的虛擬語氣

1）表建議的advise，suggest等詞的從句+（should）+動詞原形

2）wish，wouldrather，asif等后的虛擬語氣的形式同學們首先要牢記它的三種形式,它將為學習此類句子奠定基礎一、if條件句中的虛擬語氣

Ifit_____(rain)tomorrow,ourtrip_____________

(putoff).

2）if虛擬條件句構成——從句：一般現在時主句：將來時rainswillbeputoff動詞過去式(be—were)條件從句謂語主句謂語would/should/could/might+動詞原形had+過去分詞would/should/could/might+have過去分詞

動詞過去式

were+不定式

should+動詞原形would/should/could/might+動詞原形1）if真實條件句與現在事實相反與過去事實相反與將來事實相反練習：1.IfI______(know)heraddress,Iwouldwritetoher.2.Whatwouldyouhavedoneifyou__________(miss)thetrain?3.Ifhe_____________(notbeill),hewouldhavedonesomething.4.Ifit________________________(snow)tomorrow,we____________(getup)early.5.Ifyouhadaskedhimyesterday,you__________(know)whattodonow.knewhadmissedhadnotbeenillwereto/shouldsnow/snowedshouldgetupwouldknow3)錯綜條件句(混合虛擬語氣）Ifhe______hislegsyesterday,he_____withusnow.A.hadn’thurt;wouldgoB.hadn’thurt;wouldhavegoneC.didn’thurt;wouldgoD.didn’thurt;wouldhavegoneA錯綜條件句是指條件從句中的動作和主句的動作發(fā)生的時間不一致，因此，主從句的時態(tài)要根據實際的時間概念來確定

e.g.Ifshehadn’tstudiedhard,shewouldn’tspeaksowell.4)省略if的倒裝句e.g.Iftheywerehere,theywouldhelpus.如果從句中有were，should，had等詞，可省略if，并把were，should，had放句首進行倒裝。Ifyouhadcomeearlier,nothingwouldhavehappened.Weretheyhere,theywouldhelpus.Hadyoucomeearlier,nothingwouldhavehappened.Ifsheshouldbemydaughter,Iwouldn’tallowhertostudyabroad.Shouldshebemy…ManyofthecolonistswouldnothavesurvivedtheirfirstwinterinthisstrangenewlandhaditnotbeenforthelocalIndianswhotaughtthemhowtogrow,huntandfish.5)含蓄條件句有時，假設情況不以if條件句表現出來，而是隱含在某些介詞、副詞、

連詞或短語中。如with，without，butfor，butthat,but，or,otherwise等。e.g.Ilostherphonenumber,otherwise,Iwouldhaverungherup.Butforyourhelp,IwouldnothavethechancetogotoSchool.Iwasawaythatday,otherwiseI____thelecture.hadattendedwouldhaveattendedwouldattendattendedBIfyouhadnothelpedme…IfIhadnotlostherphonenumber…做含蓄虛擬題目時，要分清語境給你的信息是表格中的哪一塊？讓你填的又是哪一塊的信息？牢記：if條件句的虛擬是對（現在\過去\將來）的事實情況進行相反的假設對策：不妨把事實改成與此相反的假設，根據時態(tài)，改成相應的if條件句，再根據表格來判斷是事實情況？什么時候的條件從句？主句？分享我的體會

“但愿…”

“要是…就好了”

注意：ifonly和onlyif的區(qū)別：onlyif表示“只有”，不用虛擬語氣；ifonly則表示“要是……就好了"。IfonlyIcouldseehimagain!如果我知道他的名字該多好！2.要是我們當初聽了你的建議就好了！3.但愿我能再見到他一次！IfonlyIknewhisname!Ifonlywehadfollowedyouradvice!五個句型二asif/though+從句現在：過去：did/werehaddoneShelovesthebabyasifit_____herownson.Irememberthewholethingasifit____________(happen)yesterday.Theytalkedasifthey_____________(be)friendsforyears.注意:如果表示的事情可能會發(fā)生,方式狀語從句中的謂語動詞可用陳述語氣。werehappenedhadbeen五個句型三wouldrather(that)--現在：過去：將來：Iwouldratheryou______(pay)menow.Iwouldratheryou___________(go)tothepartyyesterday.Don’tcome.Iwouldratheryou＿＿＿＿tomorrow.過去時過去時過去完成時paidhadgonecame五個句型四五個句型五It’s(about/high)time+that--過去時（偶爾會用should+動原）你該走了。我們該出去玩了。It’shightimethatyouwent.It’shightimethatyoushouldgo.It’stimethatwewentouttoplay.表示堅持，要求，命令，建議的虛擬語氣。賓語從句。常見動詞：一個堅持，兩個命令，三個建議，四個要求。即

1.insist2.order,command3.advise,suggest,propose，(recommend)4.demand,require,request,desire

這些動詞后面的賓語從句要使用虛擬語氣用法。即從句中的動詞使用should+動詞原形，或者將should省略。

以上動詞相應的名詞構成的名詞性從句包括主語從句，表語從句和同位語也要使用虛擬語氣。從句中的動詞形式一樣（should）+v.。

某些表祝愿的固定句型：

Heavenhelphim!Godblessyou!Mayyousucceed!LonglivethePeople’sRepublicofChina!解題關鍵：1、牢記規(guī)則(表格）2、理解句意，尋找標志詞

---條件句（if,without,or,otherwise…

關鍵：確定動作發(fā)生的時間

---特定詞語(insist,demand,wish,ifonly,wouldrather,…)3、對號入座4、情態(tài)動詞的選擇(高考熱點)1.Hesuggestedthatthemeeting
