——使表達更優(yōu)雅得體高考英語二輪復習專題九【考綱解讀】

虛擬語氣是高考熱點，考生需要注意if條件從句中虛擬語氣的用法、含蓄條件句中虛擬語氣的用法和名詞性從句中虛擬語氣的用法以及虛擬語氣中倒裝的出現(xiàn)等。高考還將加大對虛擬語氣的考查。虛擬語氣表示說話人的愿望、假設、猜測或建議，而不表示客觀存在的事實。虛擬語氣通過謂語動詞的特殊形式來表示。

一“表”

1.Ifyouhadtakenmyadvice,youwouldn’thavefailedintheexam.

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

shouldhavetime,Iwouldgowithyou.——ShouldIhavetime,Iwouldgowithyou.(省if)倒裝條件句Step1、觀察思考。小結當條件句中有______，___________或______時，可省略_____,把這三個詞提到句首。Eg:IfIwere

notsobusy,Iwouldgowithyou.werehad(助動詞)shouldif注意：若條件從句為否定句，否定詞應位于主語之后。WereInotsobusy,Iwouldgowithyou.Step2、運用規(guī)律（將以下句子改為省略if的倒裝條件句）

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

Hadyoucomeearlier,youwouldcatchthebus.WereInottohaveatest,Iwouldgototheconcerttonight.含蓄條件句：

Butforyourhelp,wecouldn’thavesucceeded.

Without

air,we

wouldnotlive

evenforfiveminutes.

以上句子中虛擬條件沒有使用從句，而是通過_____短語來表示，這種句子叫做___________。這種句子往往是有主句而無從句?？捎糜谶@種句式的介詞或連詞________/_________/or/_________等。含蓄條件句butforwithoutotherwise做題關鍵：通過句意判斷準對什么時間的虛擬，然后選擇出正確的動詞形式。介詞二“混”一.混時態(tài):二.混虛實:時間錯綜的虛擬語氣Ifyouhad

takenthemedicinelastnight,youwouldbebetternow.Ifyouhadtakenthemedicinelastnight,youwouldbebetternow,butyoudidn’t.————————虛實If從句中時間與主句時間不一致。虛實錯綜的虛擬語氣

三“從句”1：虛擬語氣在名詞性從句中用法

關鍵詞★一堅持；二命令；三建議；

四要求

★

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

關鍵詞important/necessary/natural/strange/apity/ashame/suggested3:虛擬在特殊句型中的用法

關鍵詞：◆wish,asif/though,ifonly,wouldrather

表示要求，命令，建議等動詞后的賓語從句。一個堅持：insist兩個命令：order,command

三個建議：advise,suggest,propose四個要求：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。注意insistsuggestMysuggestionisthatyou(should)gohomefirstbeforecominghere.Theordercamethatthework(should)befinishedtwodaysaheadoftime…

在學習if引起的虛擬條件句時，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，在此基礎上，才能掌握倒裝的虛擬條件句及混合虛擬條

件句等。綜觀歷年的高考題及各地測試題，wish引導的賓語從句的虛擬語氣及if引導的虛擬條件及含蓄條件句是考試的重點，務必請同學們在學習中加以注意。在學習asif引導的表語從句或狀語從句中的虛擬語氣時
