Question

求解英语题目

1. Before I left the corporation, I _______ six years’ experience as the chief accountant.
A. had B. had had
C. have D. have had
为什么选B不选D

Answer 1

因为我已经有6年的经验，是在我离开（left ) 之前。离开是过去时，在过去以前，所以要用过去完成时。

追答

had＋过去分词构成过去完成时。第二个has 就是have 动词的过去分词。

而B，have had 是现在完成时，如用它，就表示到说话时有6年经验，显然与题意不符：Before I left ... （在我离开之前。）

如还有疑问，欢迎追问，有问必答！
