Only a Ribbon

    In one of the London hospitals,a short time ago,there was a young doctor. He noticed one of the patients,a ten-year-old poor girl called Katie,who had a very painful illness.

    Katie lay in her bed,day after day,with nothing to help her forget her pain and cheer up. One day the doctor noticed her trying to make a doll of her finger, and speaking to it. But she was soon tired of it,and lay back into her bed.

    That afternoon,the young doctor saw a beautiful ribbon in a shop window. He thought that it might help cheer the little girl up,so he went in and bought it for her. When he handed the ribbon to the girl,she was too surprised to speak. There were tears in her eyes. This little gift made her feel rich and happy.

    The nurse later told the doctor that the girl played with the ribbon all day long. She twisted(盘绕)it round her head. She held it in her hand while she slept.

    Some weeks later,Katie's illness became worse,and it was necessary to perform a dangerous operation. When Katie was brought into the operation mom,she cried out for the young doctor. He was brought,and he held one of the girl's hands,while the other tightly held the ribbon.

    During the operation,the ribbon fell off Katie's hand. As soon as she woke up and opened her eyes,she looked at her friend and said in a low voice,“My ribbon.”The doctor gave it to her and she smiled happily.

    It was only a little gift,but it made the girl's stay in the hospital bright with beauty and love.
