听力原文:M: Hello?
W: Hello, Debbi. This is Frank. I’m in a bit of a crisis.
M: What happened ?
W: I'm here at the station and my train leaves in twenty minutes. The problem is my suitcase is missing and all my important documents are in it. What am I going to do?
M: Where did you put it?
W: I took it out of the trunk of my taxi and left it on the sidewalls. Then I paid the driver. But when I turned around my suitcase had disappeared.
M: Oh that's unfortunate. Um...
W: There was another suitcase the same color on the sidewalk. I think someone must have got mine. I didn't have my name on mine and there's no name on this one either. What do you think I should do?
M: Well, I think the best thing to do is to go to the Railway Information desk and report this to the people there and leave the case with them. With any luck the other person will find out that he's taken the wrong case and will get in touch with Railway Information too. You should tell them to send your suitcase when it's found. Call me again before you leave to tell me what's happened. I can chase the railway people for you if necessary.
