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: 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.
