听力原文：W: Hello, Mr. Black's office.
M: Hello, may I speak with the educational advisor？
W: I'm sorry. Mr. Black's not here this morning, I'm his secretary. May I help you？
M: Yes, I would like some information about English-language schools in the United States. I'm graduating from Kuwait University this year and I want to study for my master's degree in America.
W: Have you been accepted by an American university yet？
M: Yes, I've just been accepted at the University of Chicago, but the university wrote me that I have to take an intensive English course before entering their program.
W: Well... there are many schools in the U.S. that offer English courses. Perhaps you should come down and talk to Mr. Black.
M: Ok. Could you make an appointment for me？
W: Yes, would nine o'clock tomorrow be all right？
M: No, I'm sorry. I can't come then. I have an exam at that time. Could I come the day after tomorrow at ten o'clock？
W: Yes, that will be fine, I think. May I have your name and phone number？
M: Sure, my name is Suleiman Mohammed and my phone number is 6536667.
W: Thank you, Mr. Suleiman. We'll see you Wednesday, June ninth, at ten o'clock.
