wouldshould+dosthcouldmighthaddonedid/wereshoulddoweretodowouldshould+dosthcouldmightwouldshould+havedonesthcouldmight公開課虛擬語氣在if條件句中使用方法課件第23頁23/29注意點(diǎn)1:省略if條件句有時(shí)侯在使用時(shí)可省略if,句子則可換成以下形式，即“were/had/should+主語”。如1.IfIwereaboy,Iwouldjointhearmy.2.Ifhehadtakenmyadvice,hewouldhavesucceeded.

3.Ifitwerenotfortheexpense,IwouldgotoBritain.

WereIaboy,Iwouldjointhearmy.Hadhetakenmyadvice,hewouldhavesucceeded.Wereitnotfortheexpense,IwouldgotoBritain.注:

Ifitwerenot/hadnotbeenfor…也是常見虛擬句型,意思是“要不是……”比如:Ifithadnotbeenfor

時(shí)間錯(cuò)綜條件句

當(dāng)條件狀語從句表示行為和主句表示行為所發(fā)生時(shí)間不一致時(shí)，動(dòng)詞形式要依據(jù)它所表示時(shí)間作對應(yīng)調(diào)整。

Ifyouhadfollowedmyadviceyesterday,youwouldbebetternow.Hemightbepraisednow,ifhehadmaderapidprogress.公開課虛擬語氣在if條件句中使用方法課件第25頁25/29注意點(diǎn)3:

with,without,butfor,but,or,otherwise等形式含蓄條件句。在虛擬語氣中，有句子可能沒有顯著由“if”引導(dǎo)條件從句，不過句子中隱含著一個(gè)條件，這種句子稱為含蓄條件句Withoutair(Iftherewerenoair)，therewouldbenolivingthings.假如沒有空氣話，就不會(huì)有生物了。But_foryourhelp(Ifithadn'tbeenforyourhelp)Icouldn'thavedoneit.
