2. If you had not watched television so late last night, you would not be so sleepy now.( 从句是对过去的假设，主句是对现在的假设)

4. If I had made some money last summer, I would go on holiday next month.( 从句是对过去的假设，主句是对将来的假设)
5. You didn’t let me drive. If we had driven in turns, you wouldn’t be so tired now. (从句是对过去的假设，主句是对现在的假设)
6. If I were your mother, I would let you go out this weekend. (从句是对现在的假设，主句是对将来的假设) 三、含蓄虚拟语气
虚拟语气中的“含蓄之美”指的是含蓄虚拟语气。因为有时假设的情况并不是以if引导的条件从句形式出现，而是通过一些短语等形式暗示虚拟语气的存在，常用的词语有with, without, but for, otherwise, or，even, in case of, what if(如果…将如何)等等，这种句子往往有主句而无从句 (考试时多数情况是对过去的假设)。
But for your encouragement, I would not have been admitted to this university. （过去） Without water, all lives would die. （现在）
He felt too tired yesterday, or he would have attended my party. （过去） I was having a meeting, otherwise I would have come to see you off. （过去） 四、虚名词性从句的虚拟语气
含有should +V的用法，这一部分主要是有关建议和命令的相关从句，包括主语从句，宾语从句，表语从句，同位语从句以及以之相关的形式主语宾语之类的从句。记忆口诀：一个坚持(insist)，两个命令(order, command)，三个建议(suggest, advise, recommend)，四个要求(ask, require, demand, request)。
