1、虚拟语气（二）语法导读 在上期我们已经给同学们介绍了if条件句中与现在事实相反的虚拟语气的用法，这期我们将继续学习if条件句中与过去、将来事实相反的虚拟语气以及其他虚拟语气的用法。请注意观察并分析下列句子。1. I didnt see your sister at the meeting. If she had come, I would have met her.2. If he were to come tomorrow, things would be easier.第1个句子中的“没看见”是过去的事实，这样if条件句中的“来”就与过去事实相反，“我看到她”也与过去事实相反。因此，从句的

2、谓语用“had +过去分词”，主句的谓语用“would + have +过去分词”。第2个句子中从句表达的“来”和主句表达的“是”都与将来事实相反，因此，从句的谓语用“were to +动词原形”，主句的谓语用“would +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 he had studied harder, he would have passed the 2007 NMET.b. Had the weather been good, the children could have gone out for a walk.2. a. If

5、之相对应的虚拟语气的用法：1. 与过去事实相反：从句的谓语用“had + 过去分词”，主句的谓语用“would / should / could / might + have +过去分词”。当从句的谓语中有should, were, had时，可将if省略，而将should, were, had提前，构成倒装语序。2. 与将来事实相反：从句的谓语可以用一般过去式，也可用“were to / should + 动词原形”，主句的谓语用“would / should / could / might + 动词原形”。3. 错综时间条件句：主句的谓语和从句的谓语表示的动作在时间上并不一致，对于这类虚拟

6、条件句一定要注意主、从句各表示的时间，从而判断其谓语用什么形式。4. 有些句子虽不含条件从句，但意思和条件句差不多，它们通过某些介词短语、副词来表达，如：without, otherwise, under . conditions, but for等。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.
