【正确答案】
C
【答案解析】[听力原文] W: What is it, Bob? You sounded pretty serious on the phone. Have we still got a budget problem? M: I don't know. I hope not. The meeting's on Friday. But that's not what I want to talk to you about. Er, close the door, will you? It's Marsha. W: Marsha? What about her? M: I'm worried. I don't know what to do. She's just not performing. We may have to let her go. W: Fire her? She's been with us a long time, Bob. If she leaves, it'll be a big loss to us. She's done really excellent work. M: Yes. But lately, the last month or so, in fact, there have been a lot of problems. She's changed. Not only does she have a tendency to be moody all the time, but she misses appointments, doesn't follow through on projects, and doesn't seem to plan anything till the last minute. W: Em, did she ever explain why she didn't show up for the Denver trip? M: No. She said she was sorry and that it wouldn't happen again. Something about a mix-up on arrangements to get to the airport. Now, whenever anybody mentions the subject to her, she just goes silent. I don't know. Thank goodness, David pulled us out of the hole on that one. W: Yes, he did a really fine job, filling in for Marsha like that at the last minute. M: I don't think it was the first time he's had to do that. If we knew all the facts, I think we'd find that he's been covering for Marsha on quite a few projects. What did the man do before he came to see the woman? 根据选项，问题可能是男士做了什么事情。对话开始，女士问Bob发生了什么事，并表示他在电话里的声音听起来很严肃，这表明两个人刚才在见面前通了电话。
