听力原文：M: That's fine. Thank you. It's settled. We can pick up the tickets at the box officer tonight. W: Great! M: I guess you haven't ever been to a hockey game. W: Yes. But I've read a few things about it in the papers. What time does it start, David? M: Six o'clock sharp. But we should get there a little before that if we want to see a warm-up. W: Warm-up? M: The players prepare for the game by doing some skating and shooting before it starts to loose up. W: OK! We'll have an early dinner and meet inside the front entrance. How about 5:15 ? M: That's fine. W: That'll let us pick up the tickets, and find our seats to watch the warm-up. What are they talking about?
