     "Can I see my baby?" asked the happy new mother. When the baby was in her arms, she couldn't

believe her eyes. The baby was born without ears.

     Time proved that the baby's hearing was perfect though he had no ears. He got on well with his

classmates. But one day, he said to his mother, tears in his eyes, "A big boy called me a freak (畸形物)."

     The boy's father asked the family doctor,"Could nothing be done?"

     "I believe I could graft (移植) on a pair of outer ears if they could be gotten," the doctor said. They

tried to find a person who would be helpful to the boy.

someone who will donate the ears you need. But we must keep it a secret who the person is."

made him a very successful person. He married and lived a happy life. He would ask his father, "Who

gave me the ears? I could do enough for him or her."

Slowly, the father raised the thick, brown hair. To his surprise, the son found his mother had no outer ears.

    "Mother said she was glad she never had her hair cut," his father said in a low voice, "and nobody ever
