Eg. If he had seen you yesterday, he would have asked you about it.
如果他昨天见到你,他会问你这件事的.(事实上他昨天没有见到你,因此也未能问你这件事.)
4.在含有虚拟条件句的复合句中,主句和从句的谓语都要用虚拟语气.虚拟条件从句和主句的动词形式列表如下:

与现在事实相反 动词过去式(be动词的过去式一般用were) would(should/could/might)+动词原形
与过去事实相反 Had+过去分词 would(should/could/might)+had过去分词
与将来事实相反 动词过去式/should+动词原形
