听力原文：M: May I see Dean Williams please? W: Dean Williams won't be in the office this afternoon. I'm an assistant dean. Perhaps I can help you. M: I need an extension for a paper. And my professor said I would have to get a special permission from the dean's office. W: For what course? M: Economics 201, Prof. Brown's course. W: Is this a term paper or a paper written instead of a final exam? M: It's to take the place of a final exam. W: So ordinarily, it would be due on the last day of the exam period which is this Friday. That's two days away. Don't you think you could have the paper finished by then? M: I haven't even started yet. You see, I've been sick since last Saturday with tonsillitis. I just checked out of the infirmary this morning. W: So you were in the infirmary for four days. M: Yes, from Saturday until today Wednesday. W: Generally, for an illness like this, we can postpone an exam or the due day of the paper that takes the place of an exam by the number of days the student has been ill. In your case, by four days. M: That means I'll be able to hand in my paper next Tuesday instead of this Friday. W: That's right. But first you'll have to fill out this form, giving the name of the course, your reason for needing the extension and so on. Then take the request to the infirmary to have a sign by the doctor. Then bring it back to me today. I'll have a copy sent to Prof. Brown. M: Thank you very much. I'll see you later this afternoon with the completed form. W: I'm glad you're feeling better. (23)
