听力原文：W: Good morning, Prof. Harkins. I hope I am not disturbing you？
M: Not at all, Miranda. Come right in. I'm always in my office in the morning.
W: I need an extension for the paper.
M: Why？
W: It would be due on the last day of exam period, which is this Friday,that's two days away.
M: Don't you think you could have the paper finished then？
W: I haven't even started it yet and I want to change my topic. You see, I've been sick since last Saturday with my left ear. I just checked out of the hospital this morning.
M: So you were in hospital for four days.
W: Yes, from Saturday till today, Wednesday.
M: This paper is meant to substitute for a final exam. Generally, for an illness like this, we can postpone the exam by the number of days the student has been ill, in your case, by four days.
W: That means I'll be able to hand in my paper next Tuesday instead of Friday？
M: 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 hospital to have it signed by the doctor, then bring it back to me today, and I'll have a copy sent to the dean.
W: Thank you very much. I'll see you late this afternoon with the completed form.
M: I'm glad you are feeling better.
W: Thank you, Prof. Harkins.
