学英语最重要的就是培养语感，而语感不是死记硬背出来的，而是听出来的，说出来的。要想学好英语，就必须多听、多说。脸皮要厚一点，不要害怕因为说的不好而被人嘲笑。不敢开口才是真正值得嘲笑的。今天文都四六级为大家分享2020年6月大学英语四级语法考点：虚拟条件句的倒装，希望对您有所帮助。

大学英语四级语法考点：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.
