The Doctor’s Call There was ice on the road, and the doctor’s car hit a tree and turned over three times. To his surprise, he was not hurt. He got out of the car and walked to the nearest house. He wanted to telephone the garage ( 汽车修理站 ) for help. The door was opened by one of his patients. “Oh, Doctor.” she said, “I have only just telephoned you. You must have a very fast car. You have got here very quickly indeed. There has been a very bad accident ( 事故 ) in the road outside. I saw it through the window. I am sure the driver will need your help.”
