【答案解析】[解析] 22-25
W: What? You've sold nothing?
M: Well, you know, the market is in a slump. People in this area simply aren't buying things.
W: Then you should go other places, let's say, big cities, like Chicago, New York, San Francisco, and so on.
M: Yes, Miss. I'll start as early as possible.
W: Remember you should try your best to find new customers.
M: Yes, Miss, I will.
W: Listen, try to sell all the products. Don't come back until you've succeeded.
M: I understand, Miss.
W: Where are you going first?
M: How about Washington D. C.
W: Good. Are you ready to leave now?
M: No, Miss. I came only yesterday evening.
W: Then you'd better go back and get ready to leave. By the way, which train are you going to take?
M: The 10:26 train. It's the earliest one to Washington D. C.
W: Now let me see. It's already 8:20. So you only have two hours to prepare for your trip. Get moving. You're wasting time.
M: I think I'd better go to the station to book a sleeping car first.
W: A sleeping car? That's right, and don't forget to take enough money with you.
M: Thank you, Miss. I won't come back to see you until I've succeeded.
