　　It was a cold wet night. The taxi driver hadn't had any passenger all day. When he went by the bus station, he saw a young man from the country coming out, carrying two big bags. “Aha!” thought the taxi driver. “Here's the right person to make good this bad day.” He quickly stopped the taxi and opened the door.

　　Driver：Where do you want to go, sir?

　　Young Man：To the Park Hotel.

　　The taxi driver felt very sorry when he heard that. The Park Hotel was hardly two kilometers away. The young man would give him fifty cents(美分) at most. Only fifty cents! Then he had an idea of taking the young man by a longer way－going all around the city and then back to the Park Hotel. This he did, and after a long time the taxi arrived at the hotel at last.

　　Driver：You should pay me fifteen dollars, sir. Young Man：What? Fifteen dollars? Do you think I'm a fool? You're trying to cheat(欺骗)me.

　　Driver：How can you say I…

　　Young Man：You must think I don't know my way around.

　　Driver：But…

　　Young Man：Only last week I took a taxi from the station to this hotel, I know how much I should pay.

　　Driver：Oh…Oh…all right. Now…now look…oh…

　　Young Man：I think I should call the policeman.

　　Driver：Oh, no! Please don't do that! I have four hungry children and my wife is ill in bed.

　　Young Man：All right! This time I'll forget it.

　　Driver：Oh, thank you, sir. And you are right. You needn't pay that much.

　　Young Man：You don't have to tell me that. I come from the country, but I'm as clever as you city people.

　　Driver：Yes, sir.

　　Young Man：I just won't he cheated. I won't pay you a cent more than I paid the other taxi last week…thirteen dollars!
