     One day Mr Jackson took Paul to his favourite restaurant. It was a French restaurant. The waiter was

from France. But he didn't speak to them in French."Would you like to see the menu?" he asked in a kind

way. "Yes, please," Mr Jackson said. The waiter gave them a menu each. They studied them. "You can spend

only twenty-five dollars," Mr Jackson told his son.

     The waiter asked Paul, "What would you like, young man?"

     "How much is the tomato soup?" Paul asked.

     "Six dollars," the waiter said.

     "It's very good." "How much is the duck with orange?" Paul asked next.

     "Fifteen dollars," the waiter said. 

     "How much is the chocolate ice cream?" "Six dollars," the waiter said.

     Paul added (加) it up quickly. Six plus fifteen plus six is twenty-seven. He thought he could have the

duck and the soup, or the duck and the ice cream. "I'll have the duck and the chocolate ice cream, please," he

said to the waiter.

     Paul said to his father, "My meal will cost only twenty-one dollars. Can I keep the other four dollars? His

father laughed, "No, Paul," he said. "Leave it for the waiter."
