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(yǔ)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(duì)應(yīng)調(diào)整。

with,without,butfor,but,or,otherwise等形式含蓄條件句。在虛擬語(yǔ)氣中，有句子可能沒有顯著由“if”引導(dǎo)條件從句，不過(guò)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.
