英语虚拟语气,假设情况中,什么叫与现在事实相反,与将来事实相反,与过去事实相反.需要举列说明.
英语虚拟语气的大的原则是“时态倒推法”,如下:
  与现在事实相反谓语动词用过去时,如例句所示:If I knew her telephone number,I would call her.
  If I were a bird,I would fly aroud the world.
  与将来事实相反用三种表示法:谓语动词用过去时;should do;were to do.
  例句:If he came/should come/were to come tomorrow,I would go to the airport to meet him.
  与过去事实相反谓语动词用过去完成时,例句如下:
  If I had read that book,I would be able to answer the teacher's question now.
