ПЕРЕСКАЗ ТЕКСТА СРОЧНО!!!!!!!!!!!!
Jim and Della were two young people, husband and wife. They loved each other dearly. They lived in a small room in an old house in one of the dirty streets of New York.
They worked from early morning till late at night, but they got very little money for their work. And still they had two things which were very dear to them – Jim’s gold watch and Della’s beautiful hair.
Christmas was coming and Della wanted to give Jim a nice present, but she had no money. She really did not know what to do. She sat on the sofa and began to cry. Suddenly in idea came to her. She got up and stood in front of the mirror and looked at her beautiful long hair. Then she left the house and in a few minutes she was already at the hairdresser’s shop.
"Will you buy me hair?" she asked. The hairdresser looked at her hair and said, "Yes, I will. It’s fine hair. I can give you 20 dollars for it." Della was very happy. She took the money and went to buy a present for her husband. In one of the shops she saw a very beautiful watch chain. "I’ll buy it. Jim will be very glad", she said to herself. "He needs a chain for his watch".
So Della bought a gold watch-chain as a Christmas present for Jim. When she go home, Jim was already there waiting for her. He looked at his smiling little wife and understood everything.
"Why did you do it?" he asked.
"Dear Jim, my hair will grow and I wanted to give you a present. Here it is", and she put the watch-chain into his hand.
The beautiful chain, Della’s present, was of no use to him. He had sold his gold watch to buy a Christmas present for his wife. He took a packet out of his pocket and gave it Della. She opened it and saw two beautiful combs that she seen in a shop window and wanted for so long.
