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

　　一、 基本情况

　　1、与现在事实相反

　　表示与现在事实相反的假设时，条件状语从句中的谓语动词用“过去式(be的过去式一般用were)”;而主句中的谓语动词用“would(should, could, might)+动词原形”。例如：

　　If he had time, he would attend the meeting.

　　If I were you, I would go to look for him.

　　If I were a teacher, I would be strict with my students.

　　If they were here now, they would help you.

　　练练看

　　If they __________ (have) time, they __________ (study) Italian too.

　　If there __________ (be) no gravity, we __________ (not be) able to walk.
