2009 年高考英语语法系列复习教案---虚拟语气
一、考点聚焦
1、虚拟语气用于条件状语从句中
(1)表示与现在事实相反的假设,条件状语从句中的谓语动词用“过去式(be 动词的过去式用 were)”,
而主句中的谓语动词用“would / should/ could / might + 动词原形”。如:
If I were a boy, I would join the army.
If the had time, she should go with you.
(2)表示与过去的事实相反,条件状语从句中的谓语动词用过去完成时,主句中的谓语动词则用“would
/ should / might / could + have +过去分词”。如:
If he had taken my advice, he would have eeded in petition.
(3)表示与将来事实相反,条件状语从句中的谓语动词一般过去时或should(were to) + 动词原形,
而主句中的谓语动词则用 would / should/
could might + 动词原形。如;
If it were to rain tomorrow, the football match would be put off.
(4)当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时,动词的形式要根据它所
表示的时间作相应调整。如:
If they had worked hard, they would be very tired.(从句说的是过去,主句指的是现在)
以下表格是虚拟语气用于条件状语从句中时,主句和从句谓语动词的形式:
条件状语从句主句
与过去事实相 should /would/could/might + have
had + 过去分词
反+ 过去分词
与现在事实相 would/should/could/might + 动词原
一般过去时(be 用 were)
反形
一般过去时或
与将来事实相 Would/should/cold/might + 动词原
should(were to) + 动词
反形
原形
有时侯在使用时可省略 if,句子则可换成下列形式,即“were / had / should +主语”。如:
Were I a boy, I would join the army.
Had he taken my advice, he would have eeded.
Were it not for the expense, I would go to Britain.
2、虚拟语气用于名词性从句
(1)虚拟语气在宾语从句中的运用。
①“wish + 宾语从句”表示不能实现的愿望,译为“要是……就好了”等。表示现在不能实现的愿
望,从句中的谓语动词用一般过去时;表示将来不能实现的愿望,从句中的谓语动词用“would/could + 动
词原形”;表示过去不能实现的愿望,从句中的谓语动词用“had + 过去分词”或“could(should) + have +
过去分词”。如:
