2025年6月大学英语四级语法系统复习：虚拟条件句的倒装
虚拟条件句的从句部分假如含有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"，不需要was， 即在从句中be用were代替。
If I were you, I would go to look for him.
假如我是你，就会去找他。
If he were here, everything would be all right.
假如他在这儿，所有都会好的。
典型例题
_____ to do the work, I should do it some other day.
A. If were I B. I wereC. Were ID. Was I
答案C. 在虚拟条件状语中假如有were, should, had这三个词，一般将if省略，主语提前, 变成 were, should, had +主语的形式。但应该注意，在虚拟条件状语从句中，省略连词的倒装形式的句首不可以用动词的缩略形式。如大家可说 Were I not to do., 而不可以说 Werent I to do.
