虚拟语气表示一种不能实现的假设,该语法主要用于if条件状语从句,也可用于主语从句、 表语从句、宾语从句等。 通常有三种情况: ①与过去事实相反。 ②与现在事实相反。 ③与将来事实可能相反。 虚拟语气 例: If I had come her yesterday, I would have seen him. 如果我昨天来,就会看见他了。 If you had got up earlier, you could have caught the train. 如果你早一点起床,就会赶上火车的。 与过去相反 条件从句 条件从句的谓语形式 主语的谓语形式 与过去相反 If I (you, he/she, they, we )+had +过去分词 should/would/could/might+have+过去分词 If they had studied hard, they could have done it easily that day. 1.如果他们以前努力学习的话,那天干的就会容易些。 2.如果他不听取我的建议,他就不会干得这样好。 If he had not taken my advice, he wouldn‘t have done it much better like this. If I _time last night, I _ to see the film with you . had had would have gone If he more carefully, he the car accident yesterday. had driven would not have had If I how to swim, I trapped in this island. had learnt would not have been If the staff had been more careful, the mall would not be on fire now. 主句与从句的动作发生在不同的时间, 这时主从句位于动词的虚拟语气形式因时间不同而不同, 这叫做混合条件句. 例句中从句与过去事实相反, 主句与现在事实相反 If you had asked him yesterday, you would know what to do now
