      Tom saw an advertisement in a newspaper for a beautiful, modern bicycle which cost $60, so he went to the shop which had put the advertisement in and asked to see one of their nice bicycles. The

shopkeeper was very happy to show one to Tom. He examined (检查) it carefully and then turned to the  shopkeeper, saying, “There isn’t a lamp on this bicycle, but there was one on the bicycle in your

advertisement.”  

      “Yes, Sir,” answered the shopkeeper, “but the lamp isn’t included in the price of the bicycle. It’s an

extra.”

the advertisement, it should have been included in the price you gave there.”  

     “Well, Sir,” answered the shopkeeper calmly, “there’s also a girl on the bicycle in our advertisement, but we don’t supply (提供) one of them with the bicycle, either.”
