31、第三篇 Memory One day more than fifty years ago, a young man had an accident on his mo tor-bike in which he suffered a few apparently minor injuries. There was a bruise (肿) on the left side of his forehead and some slight bleeding from his left ear. He was taken to hospital for examination but X-rays did not reveal any other in juries.
