     Mr. Li is a well-known doctor in our city. Kind but patient, he is always ready to do what he can help

his patients. One day he learned from the medical magazine that patients will feel more pain if pleasant

music is played to them. Soon he got an office in his own. So he decided to have beautifully music playing

in his waiting-room. However, on one morning, an old lady who was sitting in the crowded waiting room

became angry while listen to the music. She said, "We were all waiting to see the doctor, but he's just

playing the violin in his office instead of doing her work."
