问题补充：

He have attended the meeting this morning. He has been staying at my home for a whole day.

A. can’t

B. mustn’t

C. shouldn’t

D. needn’t

答案：

(答案→)A. can’t

B. mustn’t

C. shouldn’t

D. needn’t

解析：考查情态动词+have done的用法。句意“他不可能已经参加了今上午的会议。他在我家待了一整天。”这里表示否定的推测，can’t have done“不可能已经做了某事”；mustn’t“禁止”，不表示否定推测。shouldn’t have done“本不该做某事却做了”；needn’t have done“本不必做某事却做了”。故选A。
