虚拟语气在非真实条件句中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表示的时间作出相应的调整。
如：If you had followed my advice just now, you would be better now.If you had studied hard before, you would be a college student now.②if省略句在条件句中可以省略if, 把were, had, should提到句首，变成倒装句式。
如：If I were at school again, I would study harder.→Were I at school again, I would study harder.如果我还有上学的机会，我会更加努力学习。
If you had come earlier, you would catch the bus.→Had you come earlier, you would catch the bus.如果你来得早点，你就能赶上公共汽车。
If it should rain tomorrow, we would not go climbing.→Should it rain tomorrow, we would not go climbing.如果明天下雨的话，我们就不能登山去了。
③用介词代替条件状语从句常用的介词有with, without, but for。
如：What would you do with a million dollars? (=if you had a million dollars)如果你有100万元，你会做什么？We couldn’t have finished the work ahead of time without your help. (=if we hadn’t got your help) 没有你的帮助，我们不可能提前完成这项工作。
Without your help, we couldn’t have finished the work ahead of time.= But for your help, …= If it had not been for your help, …= Had it not been for you help, …没有你的帮助，我们不可能提前完成这项工作。
④含蓄条件句有时在虚拟语气中并不总是出现if引导的条件句，而是通过其他手段来代替条件句。
如：I was ill that day. Otherwise, I would have taken part in the sports meeting. (副词)He telephoned to inform me of your birthday, or I would have known nothing about it. (连词)A man who stopped drinking water would be dead in about seven days. (定语从句)I might have given you more help, but I was too busy. (连词)Everything taken into consideration, they would have raised their output quickly. (独立主格结构) ⑤even if, even though也可用于虚拟语气，其形式与if 从句在虚拟语气中的形式相同。
