W: Dr. Steven, I am thinking about changing my major before the end of the freshman year.
M: What are you studying now
W: I am taking three general courses and American history and American literature this semester. Last semester I took four requirements and freshman French.
M: I believe it’s not too late to change your major because you’ve mainly taken general requirements which all freshmen have to take. Also we have twelve electives so the two literature courses will be included in them, so you can change your major without losing any credit hours.
W: I am very happy to know I am still able to change my major. I am interested in writing newspaper articles, and after finishing my degree I would like to work for some newspaper firm.
M: Oh, I think you will be a good writer.
W: Dr. Steven, when do students start practical training
M: They don’t begin practical training in reporting until the sophomore year. Journalism normally is taken in the freshman year as a general background course.
W: I see. I will take the course next semester. Thank you very much for your help.
M: You’re welcome. I look forward to seeing you in my department.

M: Did you take these pictures They are very good.
W: Yes, I think they turned out very well too. I like to bring my camera with me wherever I go. That’s way if I see something attractive I can take a picture of it.
M: Carrying a big camera around is too much trouble for me.
W: My camera is really small enough. Here let me show you.
M: That is a compact camera. But you must know a lot about photography to get such professional looking results.
W: Not necessarily. This camera is simple to work. It has an automatic focus. I don’t even have to worry about focusing.
M: That’s what I need. When I take pictures, they usually come out blurry because I don’t adjust the lenses properly. And I hate photos that are out of focus. Is a camera like yours very expensive
W: Less than you’d expect. Why don’t you check the prices that Head Fields demonstrates This model was on sale there last week.
M: I think I will. It certainly won’t hurt to take a look.

W: We are going to change our meeting from Monday to Tuesday.
M: It’s all the same to me.

W: Tom, there is a new movie in town. We must go and see it.
M: OK, but let’s have breakfast first, I’m quite hungry.
W: Ok, hurry up.
