虛擬語氣一If引導的非真實虛擬條件句語氣英語的動詞一般可帶有三種不同的語氣：陳述語氣，祈使語氣和虛擬語氣。不同的語氣用動詞的不同形式來表示。虛擬語氣是一種特殊的動詞形式，一是用來表示說話人所說的話不是一個事實，而是一種假設、猜測、懷疑等常用在條件狀語從句中或讓步狀語從句中；一是表示說話人的愿望、要求、命令、建議等常用在名詞性從句中。簡言之，即：不是事實或不大可能發(fā)生的事情，就用虛擬語氣來表述虛擬語氣的概念虛擬語氣與過去的事實相反與現(xiàn)在的事實相反錯綜虛擬條件句與將來的事實相反含蓄虛擬條件句回顧與現(xiàn)在的事實相反與將來的事實相反與過去的事實相反時間if從句謂語動詞主句謂語動詞haddonedid/were1weretodo2shoulddowould/should/could/mighthavedonewould/should/could/mightdowould/should/could/mightdo1非真實條件狀語從句，SnowWhiteandSevenDwarfsCinderellaIfshehadrecogniedthequeen,shewouldnothaveeatentheappleIfshehadnoteatentheapple,___________________________shewouldnothavedieda與過去事實相反If主haddonesth,主would/should/could/mighthavedoneIf主didwere,主would/should/could/mightdob與現(xiàn)在事實相反IfIwereSnowWhite,thehuntertheprinceIfSnowWhitediednow，IwouldbethemostbeautifulwomanIfIhadabeautifuldress,IwouldbeabletoattendtheballWow!ItsuitsyouwellIfitwerenotsuitableforyou,youcouldn'tbetherightperson如果我有漂亮的裙子，我就能夠去參加舞會了。哇，太合腳了!如果這雙鞋子不適合你，你就不可能是我要找的人。CinderellaIfIhadmagicpower,Iwould_______c與將來事實相反的非真實條件句Ifitshouldsnowtomorrow,Iwouldmaeasnowman如果明天下雪的話,我會堆一個雪人If主shoulddo/weretodo,主would/should/could/might動詞原形IfIwereyou,Iwouldtryitagain在非真實條件句中，if
