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 special permission from the Dean's office. W: For what course? M: Economics, Professor Brown' s course. W: Is this the term paper, or a paper written instead of a final exam? M: It's to take the place of the final exam. W: So, it would be due on the last day of 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 infirmary this morning. W: So you were in the infirmary for 4 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 a paper that takes the place of an exam by the number of days the student has been ill, in your case, by 4 days. M: That means I'll be able to hand in the paper next Tuesday instead of this Friday. W: That's right, But first you have to fill out this form, giving the name of the course, your reasons for needing the extension and so on, then take the request to the infirmary to have it signed by the doctor, then bring it back to me today. And I'll have a copy sent to Professor Brown. M: Thank you very much. I'll see you late this afternoon with the completed form. W: I'm glad you're feeling better. (24)
