听力原文：W: Hello. Nancy Ellis speaking.

M: Hello, Dr. Ellis, my name's David Steward. My roommate, John Smith, wanted me to call you.

W: John Smith? Oh, that's right; he's in my Shakespearean English class. Has anything happened to him?

M: Nothing. It's just that he submitted a job application yesterday and the company asked him in for an interview today. He's afraid he won't be able to attend your Class this afternoon, though. I'm calling to see if it would be okay if I gave you his essay John said it's due today.

W: Certainly, that would be fine. Uh, you could either drop it off at my class or bring it to my office.

M: Would it be alright to come by your office around 4:00? It's impossible to come any earlier because I have three classes this afternoon.

W: Uh, I won't be here when you come; I'm supposed to be at a meeting from 3 to 6, but how about leaving it with my secretary? She usually stays until 5:00.

M: Fine, please tell her I'll be there at 4:00. And Dr. Ellis, one more thing, could you tell me where your office is located? John told me where your class is, but he didn't give me directions to your office.

W: Well, I'm in Room 302 of the Gregory Building. I'll tell my secretary to put the paper in my mail box, and I'll get it when I return.

M: I sure appreciate it; John was worried about not getting his paper in on time.

W: No problem. I'll look for John's paper later this evening. Good-bye, Mr. Steward.

M: Bye, Dr. Ellis. Thanks again.
