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