高中英语虚拟语气的用法

虚拟语气的用法 第一类 编辑 虚拟语气在条件句中的用法： 条件句有真实条件句和虚拟条件句两种。真实条件句所表示的假设是有可能发生的，此时主句不用虚拟语气；而虚拟条件句则表示一种假想，与事实相反或不大可能会发生，此时用虚拟语气。如： If I have time，I will go. 假若我有时间，我就去。 （陈述语气） If I were you，I would go. 假若我是你，我就去。 （虚拟语气 ） 时态类型 主句谓语形式 条件句的谓语形式 例句 与现在事实相反 would/should/could/might+ V原形 动词过去式 did *be 多用were 1. If I were you, I should study English. 2. I would certainly go if I had time. 与过去事实相反 would/should/could/might + have done 动词过去完成式 had done 1. If you had taken my advice, you would not have failed in the test. 2. If I had left a little earlier, I would have caught the train. 与将来事实相反 would/should/could/might + V原形 ①动词过去式 ②should +V原 ③were + to do 1.If you came tomorrow, we would have the meeting. ① 2. If it were to rain tomorrow, the meeting would be put off.③ *规律总结：从句都往过去推一个时态，如：与现在相反的if从句就用过去时；与过去相反用过去完成时（即过去的过去） 注：特别说明 1、l would/should/could/might主句谓语中的should主要用于第一人称后；would表示结果还表示过去经常常常做某事，might表示可能性，could表示能力、允许或可能性。比较： If you tried again ，you would succeed. 要是你再试一试，你就会成功的。 (would
