________ your letter, I would have started off two days ago.

A.If I received

B.Should I receive

C.If I could have received

D.Had I received

答案

答案:D

题目分析:考查虚拟语气,从后面的主句的时态可知if条件句要用和过去相反的虚拟语气,if的非真实条件句可以省略if,提前had,were,should,Had I received="if" I had received,选D

点评:考查虚拟语气的时候要注意和不同的时间相反的情况,主从句的时态是不一样的。要注意记忆。
