—Excuse me, visiting hours are over.It' s time for you to leave.

—I' m sorry, I didn't know the time or I ______ earlier.

A.will leave

B.would leave

C.had left

D.would have left

答案

答案:D

题目分析:考查虚拟语气。本题的关键词是or ,or常用于含蓄条件句中。根据句意,or等同于If I had known the time,与过去相反,主句使用would/could/should/might+have done ,因此选答案D

点评:含蓄条件句要注意一些信息词,如with,without,but for but,or,otherwise等,虚拟语气考查还要注意判断出是与过去,现在还是将来相反,再根据其规则使用相应的结构。
