单项选择题

听力原文：W: Hello, University of Sidney. May I help you?
M: Yes. I'm looking for information on courses in computer programming.
W: Do you want a day or evening course?
M: Well, it would have to be an evening course since I work during the day.
W: Uh-huh. Have you taken any courses in data processing?
M: No.
W: Oh, well, data processing is a prerequisite course. You have to take that course before you can take computer programming.
M: Oh, I see. Well, when is it given? I hope it's not on Tuesdays.
W: There's a class that meets on Monday evenings at seven.
M: Just once a week?
W: Right. But that's almost three hours--from seven to nine forty-five p. m.
M: Oh. Well, that's all right. I could manage that. How many weeks does the course last?
W: Let me see.., oh, yes, twelve weeks. You start the first week in September and finish.., oh... just before Christmas. December twenty-first.
M: And how much is the course?
W: That's 300 dollars, and that includes the necessary computer time.
M: OK. By the way, is there anything that I should bring with me?
W: No. Just your checkbook.
M: Thank you so much.
W: You're very welcome. Bye.
M: Bye.
