英语虚拟语气的三种时态

Answer 1

英语虚拟语气的三种时态：

（1）与现在事实相反。

若与现在事实相反，虚拟语气的条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”。如：

If I knew her number I could ring her up.

（2）与过去事实相反。

若与过去事实相反，虚拟语气的条件从句的谓语用过去完成时(had+过去分词)，主句谓语用“should (would, could, might)+have+过去分词”。如：

If we had found him earlier we could have saved his life.

（3）与将来事实相反。

若与将来事实相反，条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”。如：

If he went，would you go too?
