导读：英语中的语气分为陈述语气、祈使语气、虚拟语气三类。根据同学们的普遍反映，其中，虚拟语气的用法让大家感到非常头疼。为了帮助同学们解决这个“心头大患”，新东方学校的小编为大家准备了一套“虚拟语气大餐”，对症下药地解决“对隐含条件的虚拟语气和从句中虚拟语气的运用”这个难点。希望同学们在学习过后，能够进一步了解虚拟语气的结构，并能对虚拟语气进行简单地运用。

第一部分 虚拟语气用于含(或隐含)条件状语从句的复合句

　　二、 特殊情况

　　1、主句和从句的谓语动词所指的时间不同(错综时态虚拟)

　　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，动词的形式要依据它所表示的时间来调整。

　　If you ha d worked hard, you would be very tired.

　　If you hadn’t watched that late movie last night, you wouldn’t be so sleepy now.

　　Many dead people would now be alive if they had not attempted to return for something.

　　If Paul had received six more votes in the last election, he would be our chairman now.

　　【练练看】

　　If you _________ (ask) him yesterday, you _________ ( know) what to do now.

　　If it _________ (rain) last night, it _________ (be) very cold today.
