 16.4 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.
