虚拟条件句的从句部分如果含有were,should,或had,可将if省略,再把were,should或had移到从句句首,实行倒装。
Weretheyherenow,theycouldhelpus.
=Iftheywereherenow,theycouldhelpus.
Hadyoucomeearlier,youwouldhavemethim
=Ifyouhadcomeearlier,youwouldhavemethim.
Shoulditrain,thecropswouldbesaved.
=Wereittorain,thecropswouldbesaved.
注意:
在虚拟语气的从句中,动词'be'的过去时态一律用"were",不用was,即在从句中be用were代替。
IfIwereyou,Iwouldgotolookforhim.
Ifhewerehere,everythingwouldbeallright.
_____todothework,Ishoulddoitsomeotherday.
A.IfwereIB.IwereC.WereID.WasI
答案C.在虚拟条件状语中如果有were,should,had这三个词,通常将if省略,主语提前,变成were,should,had+主语的形式。但要注意,在虚拟条件状语从句中,省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说WereInottodo.,而不能说Weren'tItodo.
