小学英语语法知识点：虚拟条件句的倒装
小学英语语法知识点：虚拟条件句的倒装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.
