Dick was a college student. His parents were poor, so he had to work during his holidays to get enough money for his studies.
One summer he got a job in a butcher’s shop(肉店) during the daytime, and another in a hospital at night. In the shop, he learned to cut and sell meat. He did very well and almost all people knew him. In the hospital, of course, Dick did the easiest jobs. He helped to lift people and carry them from one part of the hospital to another. Both in the butcher’s shop and in the hospital, Dick had to wear white clothes.
One day a woman was ill and was sent to the hospital. The doctor said that she needed an operation (手术) at once. The woman was already frightened when she thought about the operation. When she saw the young man coming to get her, she was even more frightened.
