hadpassedstopped【語法精講】虛擬語氣除了虛擬條件句和賓語從句中的虛擬語氣以外,還有一些比較特殊的情況:一、虛擬條件句的特殊用法1.錯綜時間條件句有時條件句的動作與主句動作發(fā)生的時間不一致,這時動詞的形式應(yīng)根據(jù)它們各自表示的時間加以調(diào)整。*Ifyouhadtakenmyadvicethen,youwouldn’tbeintroublenow.如果當(dāng)時聽我的勸告,你現(xiàn)在就不會有麻煩了。(從句表示過去,主句表示現(xiàn)在)*IfIwereyou,Iwouldhavetakenhisadviceyesterday.如果我是你,昨天我就會采納他的意見。(從句表示現(xiàn)在,主句表示過去)2.含蓄條件句(1)有時假設(shè)的情況不用條件句表達(dá),而是用butfor,without等介詞(短語)或上下文來表示。*Withoutelectricity,theworldwouldbedark.如果沒有電,世界將一片黑暗。(2)用連詞otherwise,or等暗示后文與前面的情況相反,從而引出后文的虛擬語氣。*Iranallthewaytothecinema,otherwiseIwouldhavemissedthebeginningofThe

Monkey

King.我一路跑到電影院,不然我會錯過了電影《大鬧天宮》的開頭。【即學(xué)活用】語法填空。(1)Hisshipwasdelayedbecauseoftheheavyfogyesterday;otherwiseI__________________(pick)himupontime.

(2)Ifshehadstudiedhard,she________(be)acollegestudentnow.

(3)Butfortherain,we__________________(finish)theworkalready.

(4)I_______________(go)tomycousin’sbirthdaypartylastnight,butIwasnotavailable.

wouldhavepickedwouldbewouldhavefinishedwouldhavegone二、某些名詞性從句中的虛擬語氣1.主語從句中的虛擬語氣(1)在“Itis+important/necessary/natural/strange/essential/apity+that...”句型中,謂語動詞用(should+)動詞原形。*Itisstrangethatthepooroldmanshouldhavebeeninvitedtohiswedding.那位貧窮老人竟然被邀請參加他的婚禮,真是奇怪。*ItisapitythatLucy(should)besocareless.真遺憾露西竟這樣粗心?！久麕燑c津】這種從句表示的是事實。如果說話人對這種事實表現(xiàn)出驚奇等情感,就可用虛擬語氣。反之,如果不表示驚奇等情感,that從句也可用陳述語氣。*Itisapitythatyoucan’tgowithus.很遺憾你不能和我們一起去。(2)“Itisdesired(suggested,ordered,requested,proposed,required等)+that從句”句型中,從句謂語動詞用“(should+)動詞原形”,其中should可省略。*Itisdesiredthatwe(should)geteverythingreadybytonight.希望一切在今晚準(zhǔn)備好。2.表語從句和同位語從句中的虛擬語氣表示“建議、要求、命令”等的名詞如asuggestion,proposal,order,demand,advice,request等后跟表語從句和同位語從句時,從句中的謂語動詞用“(should+)動詞原形”。*Hegavetheadvicethatwe(should)dotheworkcarefully.他建議我們認(rèn)真做這項工作。*Mysuggestionisthatwe(should)sendafewpeopletohelptheothergroups.我的建議是我們派幾個人去幫助別的小組。【即學(xué)活用】(1)語法填空。①Theteacheragreedtothesuggestionthatthestudents_______________(give)twoweekstopreparefortheexam.

②Myrequirementisthatthephone__________________(repair)assoonaspossible.

③Itissuggestedthatyou_________(go)onabalanceddietatthesametime.

(should)begiven(should)berepairedshouldgo(2)同義句轉(zhuǎn)換。Itisimportanttoknowwhattodowhenyouareindangeroussituationssuchasafire.→_________________________________whattodowhenyouareindangeroussituationssuchasafire.

Itisimportantthatyou(should)know三、虛擬語氣在其他句型中的用法1.asif/asthough從句以及ifonly后的句子常用虛擬語氣asif/asthough/ifonly時間謂語動詞的虛擬形式與過去相反had+過去分詞與現(xiàn)在相反一般過去時(be動詞用were)與將來相反would/could/might+動詞原形*Hetalkedabouttheaccidentasifhehadseenit.他談起這次事故來好像他看到了一樣。(與過去事實相反)*IfonlyIhadenoughmoneytobuyaniPhone11.如果我有足夠的錢買一部iPhone11,那該多好。(與現(xiàn)在事實相反)【名師點津】

如果asif/asthough后的從句有明顯的跡象表示可能發(fā)生時,不用虛擬語氣。*Itissocloudy.Itlooksasifitisgoingtorain.天這么陰,似乎要下雨了。2.It’s(high/about)time后的從句用虛擬語氣從句謂語動詞常用過去時,也可用should+動詞原形,但should一般不省略。*Itishightimethatwespared/shouldsparenoefforttoprotecttraditionalChinesecultures.到了我們該不遺余力地保護(hù)中國傳統(tǒng)文化的時候了。*It’sabouttimethatweshouldfight/foughtforourdreams.我們該為我們的夢想而奮斗了?！炯磳W(xué)活用】(1)語法填空。①Theupsetmotherthoughttoherself,“IfonlyI_____(know)what’sgoingoninmylittleboy’sheadrightnow.”②Jackisagreattalker.It’shightimethathe___(do)somethinginsteadofjusttalking.③Don’thandlethevaseasifit__________(make)ofsteel.
