【答案解析】[听力原文]6-7
W: John, my dad's new MP3 player seems to be missing. Did you move it?
M: No, I didn't. Isn't it right next to the computer?
W: No, and I don't see it anywhere. I have the feeling one of our party guests took it.
M: Really? What are you going to do now?
W: I'll just tell my parents what happened, I guess.
M: Then they'll know you had people over without permission. Won't they be angry about that?
W: Probably. I wish I'd done that from the start, instead of keeping my plans secret. They'd have said no to a party, and the MP3 player would still be here.
