摘要：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.
