高考英语语法一轮复习 虚拟语气（共11张PPT）

虚拟语气 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。 一、虚拟语气在条件状语从句中的用法。 虚拟语气常见用法　　　　　　 The volleyball match will be put off if it rains. Fact! The weatherman forecasted no rain for tomorrow; but if it should rain tomorrow, they wouldn’t go for an outing. 虚拟语气在条件状语从句的运用　 条件从句 If 从句的谓语形式 主句的谓语形式 现在 过去 未来 did（were） had done would/should/could/might +v.（原） would/should/could/might +have+p.p. would/should/could/might +v.（原） did should +v. were to do 虚拟语气假设条件句型注意点： 1. 非真实条件从句谓语动词发生的时间与主句的谓语动词不一致，叫做错综条件虚拟语气,也称为混合虚拟。主句和从句的谓语动词要依照假设的时间而定。 如果你开车时不是太快，现在你就不会在医院了。 If you hadn’t driven too fast , you wouldn’t be in hospital now. 2.假设条件虚拟倒装。 条件从句中有should， were， had三个助动词可 以把if省略，并将这三个词提至句首。 If I were you, I would give it up. Were I you, I would give it up. If you hadn’t broken the rule, you wouldn’t be in troubles now. Had you not broken the rule, you wouldn’t be in trouble now. If it should rain tomorrow, what should we do? Should it rain tomorrow, what should we do? ____
