3个回答

  • B.Had you come

    If you had come yesterday,you would have met Professor Jones.But now he has left for London.

    虚拟语气的用法,表示与过去事实相反

    原句的意思是如果你昨天来就好了,你就可以遇到Jones教授了.但是现在他已经离开到伦敦了.

    这是一个对过去时态的虚拟,与过去事实相反,结构应该是 if +主语+had +过去分词,主语+would(should could might)+have +过去分词,也可以省略if,用had +主语+过去分词.
