2. 错综时间句：if条件句和主句时间不一致

If you _____ (ask) him yesterday, you _____ (know) what to do now. 3. 含蓄条件句：一些介词短语，如：but for, without, otherwise, 等可代替if 条件句

It is suggested (decided, ordered, demanded, required) + that从句

例: It is necessary that we should clean the room every day. It was a pity that you be so careless. It will be suggested that she should finish her homework this afternoon. （3）表语从句，同位语从句中的虚拟语气

作advice , idea , order, demand, plan, proposal, suggestion, request等名词的表语从句和同位语从句，

其谓语动词要用虚拟语气的结构“（should ）+动词原形”。

例：
