听力原文：W: Hello.

M: Hi, Jill. This is Joe.

W: Great to hear from you, Joe. How have you been doing？

M: To tell the truth. I'm very worried about our final exams next month. For one thing, I can't sleep.

W: I went through the same thing last year.

M: That's exactly why I'm calling you. Do you have any suggestions for coping with anxiety？ You know how I hate exams.

W: Well, last year the university offered a stress management course at about this time. Have you been in contact with the student help services？

M: No. I haven't had time.

W: Funny, isn't it？ Just when students need help most we can't afford time to get it.

M: Well, perhaps I should find out more about this stress management course since I' ye got to get better.

W: I suggest you call the health services tomorrow. They open at 9 a.m.

W: Best of luck. And have a good night sleep.

M: That's easier said than done.
