虚拟语气（一）语法导读 虚拟语气表示说话者的愿望、假设、怀疑或推测，所说的话或与现在事实相反，或与过去事实相反，或与将来事实相反，它通过谓语动词的特殊形式来表示。我们现在就以下面这两个句子为例来迈入虚拟语气的大门。1. He is busy now. If he were free, he would go with you.2. I wish I could go to the movie with you tonight, but I have to finish my homework then. 第1个句子中的“忙碌”是现在的事实，这样后面句子中的“空闲”则是与现在事实相反的假设，所以“和你一起去”也与现在事实相反。因此，if从句的谓语用一般过去式were（be动词的过去式一般用were），而主句的谓语用“would +动词原形”。第2个句子中的主句的谓语是wish，从后面but表示的转折的意义看，“今晚我去看电影”是不现实的，所以从句的谓语用“could + 动词原形”。寻规找矩请观察下列几组句子，特别要注意其中谓语动词的不同形式。1. a. If I were you, I would accept the invitation and attend the meeting.b. If he studied harder, he would pass all the examinations.2. a. I wish it were spring in my hometown all the year round.b. Peter wishes that he had studied law instead of literature when he was in college.c. I wish it would stop raining soon so that we could go hiking as planned.功能小结通过观察分析以上几组例句，我们可以发现与之相对应的虚拟语气的用法：一、虚拟语气用在条件句中与现在事实相反：从句的谓语用一般过去式（be动词的过去式通常用were），主句的谓语用“would / should / could / might + 动词原形”。二、虚拟语气用在wish引导的宾语从句中在wish 后接的宾语从句中，谓语要用过去的某种时态表示虚拟语气。1. 表示现在不能实现的愿望，从句的谓语用一般过去式；2. 表示过去不能实现的愿望，从句的谓语用“had +过去分词”或“could / would + have + 过去分词”；3. 表示将来不能实现的愿望，从句的谓语用“would / could + 动词原形”。即学即练 I. 用括号内所给动词的适当形式完成下列句子。1.
