听力原文：M: Sue, I haven't seen you for a while. How are you doing？
W: Hi, Dave, I have some excellent news. I won first prize in the computer software competition. We had a party last night. I'm sorry you didn't make it to be there.
M: Oh, yeah, I had an appointment with my supervisor. It was such a great pity. Tell me, what's the prize？
W: I've won a trip to Sydney. You know what？ That's been the place of my dreams for so many years.
M: Really？ Why do you like it particularly？
W: I love the sunshine on the beach, the soft wind from the sea, and I have friends there. They invite me to visit them every year. I really miss them.
M: That's great! But how will you get there？
W: Fly, of course. It's much too far to swim.
M: I hate flying. What terrifies me most is the thought of not having my feet safe on the ground. And three other things happen: my stomach turns, my face goes pale, and I break into a cold sweat.
W: But if you want to travel, you have to fly.
M: That's tree. But if I were to fly, I'd have to get some medicine from the doctor.
W: That must cause you a lot of trouble. I heard people say that more practice will make the condition better. Why don't you try it？
M: I definitely want to get rid of the problem. But...to fly more often？ Oh, the idea itself will kill me.
