听力原文：M: Is Mr. Cheng in the office? W: He won't be in the office today. I'm his assistant. 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. W: For what course? M: World history, 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 the final exam. W: So usually, 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 flu. I just left hospital this morning. W: So you were in the hospital for 4 days? M: Yes, from Saturday until today. W: Generally for this kind of case, we can postpone the exam or the due day of a paper by the number of days the student has been iii, in your case, by 4 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 have to fill out this form, writing down the name of the course, your reasons for the extension and so on, then take the request to the hospital to have it signed by the doctor, then bring it back to me today. And I'll have a copy sent to Prof. Brown. M: Thank you very much. I'll see you late this afternoon with the completed form. W: See you then. (20)
