Michael: Hi! I saw you yesterday with John. We room together. I’m Michael.
Jane: Oh, hi, Mike. How are you doing?
Michael: I’m okay, but school has been really mad since I came. I haven’t even had a chance to breathe!
Jane: I know. It’s especially crazy when you’re a freshman. Hey, what’s your major?
Michael: Travel and tourism.
Jane: Well, what do you plan to do after graduation?
Michael: Uh...I really haven’t decided. I think I’d like to work for a travel agency in this area. What about you?
Jane: Well, when I first started college, I majored m physics, but later I realized I might have a hard time finding a job in that field. I ended up changing to computer science. Finding a job in the IT industry shouldn’t be as difficult.
Michael: Have you got a part-time job to support yourself through school?
Jane: Well, I’m on a four-year scholarship that pays my tuition.
Michael: Wow, lucky you!
Jane: Yeah, how about you? Are you paying for school yourself?.
Michael: Sort of. I work weekends at a travel agency.
Jane: A travel agency? That seems like a perfect experience for you ! What do you do there?
Michael: I’m a tour guide. I show tour groups around the city.
Jane: Wow, your English must be pretty good then.
Michael: Actually, they’re all Chinese tourists. That’s why I got the job.
