1、精选优质文档-倾情为你奉上初中英语虚拟语气讲解及练习 英语中的语气分为陈述语气、祈使语气、虚拟语气三类。虚拟语气表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。如果假设的情况可能发生，是真实条件句，这种情况下谓语用陈述语气。如： If time permits, well go fishing together.如果时间允许，我们就一起去钓鱼。 如果假设的情况是不存在的或不大可能发生的，则是虚拟条件句。如： If you had come yest
