听力原文：M: Professor Day. May I see you for a minute? W: Sure. Come on in. What's the matter? M: I' ve got a problem. I need your technical writing class, so I went early to the registration area, but by the time I got to the front of the line, it was closed. See, my advisor signed my course request and everything. W: That' s a big class already. If it is closed, that means I have 50 students in it now. M: I' m not surprised. It' s a really good class and many students want to attend it. W: Can' t you take it next year? We offer it every fall. M: Well, that' s the problem. I' m supposed to be graduating this spring. But, of course, I can' t graduate without your class. W: I see. In that case, I' ll sign for you. It looks like there will be 51. Take this form. back to the registration area. They will get you in. M: Thanks, Professor Day. I really appreciate this! (20)
