Nick was a clever college student. His family was not rich, so he had to work after school and during his holidays to get enough money for his studies.
One summer he got a job in a butcher's(肉铺)  during the daytime and the other in a hospital at night. In the shop, he learned to cut and sell meat. He did so well that the butcher often left him to do all the things while the butcher went into a room behind the shop to do the accounts(账目). In the hospital, of course, Nick was told to do only the easiest job. 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, Nick had to wear white clothes.
One evening in the hospital, Nick had to help to carry a woman from her bed to the operating-room. The woman was afraid of the operation. When she saw Nick, she cried, "No! No! Not the butcher! I won't let the butcher operate on me!" With these words, she fainted(昏倒).
