对话文本
F: May I help you?

M: Yes, I would like to exchange some money.

F: what currency would you like to trade in?

M: I would like to exchange Chinese RMB for American dollars. Do you accept $100 bills?

F: No problem, we can accept any denomination. How much would you like to exchange today?

M: Well, that depends on the rate. How much is the RMB trading at today?

F: It's a shame you didn't come a little earlier, the exchange rate was reset yersterday afternoon. The American dollar is now worth 7.45RMB.

If you would like to sell RMB, we can give you a rate of 7.35.Will that be all right?

M: I guess, here, give me 5,000 RMB worth. I might as well exchange a little extra. Who knows what the exchange rate will be tommorow!
