     Mrs. Black is sixty-nine years old. She only has a daughter named Sandra. Mr. Black died twelve

years ago. Mrs. Black was very sad and lived in her house alone. Two years ago her daughter had a

baby. The young woman was busy all the time and had no time to look after her son James. She asked

her mother to live with them.

     The old woman had to sell her house and moved there. She was strong and could do all the

housework. And the family liked her.

      Last autumn Mrs. Black went to do some shopping. A car hit her and her leg was hurt. She had to

be in hospital for three months. She couldn't do anything after she came back. At first her daughter was

kind to her, but soon she began to be tired of (讨厌) her. The old woman wanted to leave, but she had

no money to buy a house and nobody could take care of her. She didn't know what to do.

      One morning Mrs. Black broke a plate. It made her daughter angry. She told James to buy a

wooden (木制的) plate for his grandma. That afternoon James came back with two wooden plates. She

was surprised and asked, "Why did you buy two plates, son?"

     "One is for grandma," answered the boy, "the other is for you! You will also have to use a wooden

plate when you're old, I think."

      The woman heard this and was sad. She cried for long. Now she is kind to her mother as she was

before.
