2020届高考英语二轮复习专项语法课件：虚拟语气(共18张PPT)

虚拟语气 二轮复习 1、错综时间条件句 当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时，被称为“错综时间条件句”，动词的形式要根据它所表示的时间作出相应的调整。 If it had rained last night, the ground would be wet now. 虚拟条件句要注意： 2、if省略句 当条件状语从句中谓语含有were, had, should时，可以省略if，将were, had, should提到从句句首，变为倒装句式。 If I were at school again, I would study harder. —Were I at school again, I would study harder. If you had come earlier, you would have caught the bus. —Had you come earlier, you would have caught the bus. If it should rain tomorrow, we would not go climbing. —Should it rain tomorrow, we should not go climbing. 3、含蓄条件句 有时候为了表达的需要，在虚拟条件句中并不是总会出现if引导的条件句，而是通过其它手段来代替条件句，常见有with, without, or, otherwise, but, but for, but that等。 What would you do with a million dollars?(=If you had a million dollars) Without your help, we couldn’t have finished the work ahead of time. =But for your help, ... =If it hadn’t been for your help, ... I was ill that day. Otherwise, I would have taken part in the sports meeting. =If I hadn’t been ill that day, I would have taken par
