     A traveler came out of the airport. There were a lot of taxis. He asked every taxi-driver 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 expensive, 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 100dollars and said, ”What

about tomorrow?” The taxi-driver looked at the man and said, “Tomorrow? It’s another 100 dollars "

But the man said, “That’s OK! See you tomorrow.” The taxi-driver was very pleased.

museums again. And in the evening they went back to the hotel. The man gave the taxi-driver 100 dollars
