It was a dark and cold night．The taxi driver didn’t have even one passenger(乘客)all day．When he went by the railway station,he saw a young man coming out with two bags in his hands．So he quickly opened the door of the ear and asked,“Where do you want to go,sir?” “To the Star Hotel,”the young man answered．When the taxi driver heard that,he didn’t feel happy any mole．The young man would give him only three dollars because the hotel was not far from the railway station．But suddenly,he had all idea．He took the passenger through many streets of the city． After a long time,the ear arrived at the hotel at last．“You should pay me fifteen dollars,”the car driver said to the young mall．“What Fifteen dollars Do you think I’m a fool(傻瓜)?”Only last week,I took a taxi from the railway station to this same hotel and I only gave the driver thirteen dollars．I know how much I have to pay for the trip．I won’t pay you one dollar more than I paid to the other taxi driver last week．
