if虚拟条件句的倒装_虚拟条件句的倒装
【shitiku.jxxyjl.com--英语语法词汇】
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。were they here now, they could help us.
=if they were here now, they could help us.
had you come earlier, you would have met him
=if you had come earlier, you would have met him.
should it rain, the crops would be saved.
=were it to rain, the crops would be saved.
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。
if i were you, i would go to look for him.
如果我是你，就会去找他。
if he were here, everything would be all right.
如果他在这儿，一切都会好的。
典型例题
_____ to do the work, i should do it some other day.
a. if were i b. i were c. were i d. was i
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 were i not to do., 而不能说 weren"t i to do.
