听力原文:W: Oh, Larry, I have been meaning to talk to you.
M: Hi, Jenis. What's up?
W: I have this great job lined up to manage the clothing store at the mall.
M: So what's the problem?
W: Well, one of the professors in my department just told me about a summer internship program that's available. She thinks I might be able to intern in the office of the Way fare Hotel here in town.
M: That sounds like a great opportunity too. Why not take advantage of it?
W: I'd love to, especially since I'm studying hotel management. It would be a great way to get some practical experience in my field.
M: And you never know, it might lead to something with them after graduation. They are on of the biggest hotel chains in the area.
W: You're right. But the drawback is I wouldn't be making nearly as much money as I would be working in the clothing store, not to mention the discount I could get on clothes there.
M: How much is the internship paid?
W: They pay their internship a small stipend and give them free room and board for the sum- mer.
M: Well, if I were you, I would take the internship anyway. You could always get a job during the school year to make a few extra bucks.
