【正确答案】 A

【答案解析】[听力原文]
   W: Have you noticed that Henry hasn't been acting like himself lately? He's skipped at least four days of work this month, and I overheard him talking to Mike about going to the hospital.
   M: I'm not sure if I should say anything, but he is going through some family problems at the moment. His wife might need heart surgery soon.
   W: Oh, that's terrible. If you talk with him, though, you might want to mention that the head of his department has noticed a decline in his work.
选项A正确。选项B混淆了actor(演员)和act like(举止像……)。选项C错误，去医院只是Henry举止反常的一个细节。选项D错误，Mike只是作为消息来源被提及一次。
