d. =Were it to rain, the crops would be
_____ to do the work, I should do it some other were I
were I I
, 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。但要留意，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.










混合条件句
主句与从句的动作发生在不同的时间，这时主，从句谓语动词的虚拟语气形式因时间不同而不同，这叫做混合条件句。例如：条件句动作发生在过去，主句的动作发生在现在)谓语动词要依据表示的时间进行调整。
If you had asked him yesterday, you would know what to do now.
（从句与过去事实相反，主句与现在事实相反。）
If it had rained last night (过去), it would be very cold today (现在).Wish 句型 表达“但愿…，要是…多好”的语气
表示与事实相反的状况，或表示将来不太可能实现的愿望。其宾语从句的动词形式为：
真实状况 wish后
从句动作先于主句动词动作
现在时
过去时










（be的过去式为 were）
从句动作与主句动作同时发生 过去时
过去完成时 （had + 过去分词）
将来不大可能实现的愿望
将来时 would/could +
