     Once, there was a man whose name was Tom. He loved his wife very much. A special day was

coming. It was his wife's birthday. Tom decided to buy something for her.

     The next day he went home and said to his wife, "I bought something for you." "Thank you!" said his

wife happily. "What have you bought for me?" "I've bought a gold ring. Here it is." He took it out for his

wife to see. Carelessly, he dropped it onto the ground. He began to look for it on the ground, but it was

dark in the house and he could not see anything. Then he went out and began to look for it in the street.
