A traveler came out of the airport. There were a lot of taxis. He asked every taxi driver about his name. Then he took the third one. It cost 5 dollars from the airport to the hotel. “How much does it cost for the whole day?” The man asked. “100 dollars,” said the taxi driver. This was very dear (昂贵的), but the man said it was OK.

The taxi driver took the man everywhere. He showed him all the parks and museums in the city. In the evening they went back to the hotel. The traveler gave the taxi driver 100 dollars and said, “What about tomorrow?” The taxi driver looked at the man and said, “Tomorrow is another 100 dollars.” And the man said, “That’s OK! See you tomorrow.” The taxi driver was very pleased.

The next day the taxi driver took the traveler everywhere again. They visited all the parks and museums again. And in the evening they went back to the hotel. The man gave the taxi driver 100 dollars again and said, “I’m going home tomorrow.” The driver was sorry because he liked the traveler and 100 dollars a day was a lot of money. “So you are going home. Where do you come from?” He asked. “I come from New York.” “New York,” the taxi driver said, “I have a sister in New York. Her name is Susan. Do you know her?” “Of course I know her.
