高考英语一轮复习——虚拟语气讲解及练习（附答案）

高考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, we'll 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 yesterday, you would have met that famous professor.如果你昨天来，你就会见到那位著名的教授了。 虚拟语气的基本形式和用法在含有虚拟条件句的复合句中，主从句的谓语都要用虚拟语气。 I. 含有条件状语从句的复合句 一、与现在事实相反 连接词 条件从句 结果从句 If 1.动词过去式(或were) 2.助动词（过去式）+动词原形 Should Would +动词原形 could might If had the time, John would make a trip to China to see the Great Wall.
