___ he would have succeeded in the examinations.

题目

___ he would have succeeded in the examinations.
A If he has worked hard B If he works hard
C If he worked hard D Had he worked hard
选什么?为什么?

答案

选D
这是虚拟语气最常考的表现手段
与过去事实相反,从句用had+过去分词来体现.正解应为If he had worked hard,但又因为省略了引导词If故用半到装句,所以将助动词had提前.
