听力原文:W: Hi, Zach. M: Hey, Lisa. What are you doing here? W: I work here on weekends. How come you decided to come to the travel agency? Planning a trip? M: Yeah, well, you know our breaks are coming, and I need a quick getaway trip somewhere. W: Well, someone's got the money to burn. But we hardworking students need a break too. M: I'm going to tell you upfront Lisa. It's not what you think. I'm on a tight budget like everyone else here but I have to get out of this town for a while. W: Where to? M: Florida. I'll go see a Miami Dolphin football game. W: And you need a flight for next week? Well, you are the one who leaves things to the last minute but hmm.., let me take a look at the screen... United's got one to Miami, but a bit expensive, so let me see if there is anything else available. M: Preferably below $400 for return, can you swing it? W: One by Phoenix Air for $350. It's a small plane though. Are you sure you don't want me to check again for other flights? It would only take a second. M: No, that sounds within my range. W: All tight. Just let me phone in and confirm the times. (9)
