II'll tell Mary about her interview tomorrow.
You ________ her the day before yesterday.
A. ought to tellB. would have toldC. must tellD. should have told
答
D 是正确的答案请给我过程谢谢should have told 的意思就是“你前天就应该告诉她了”，在这里最贴切。ought to tell her 只能用于还未完成的动作，而主语已经将消息告诉mary了。would have told her 也不合适，因为它意味着主语应该却没有告诉mary。must tell her （一定要告诉她）肯定也是错的，因为它表明动作还没有完成，是一种命令的语气。
