Mr King worked in a factory. He liked playing soccer and spent much time on it, so he was sometimes late for work. His boss was so angry that he fired(解雇) Mr King. Mr King couldn't find another job. Finally he got into trouble and lived a difficult life.
One of his friends felt sorry for him and introduced(介绍) him to a headmaster, whose school was just in need of swimming coaches. Mr King began to teach the school children to swim. He wasn't a good coach. Two months later, the children learned nothing. Few of them could swim.
It was a hot Saturday. The children wouldn't stay in the classroom and wanted to swim in the river. Mr King failed to stop them. Before they started, he drew a red line below the knee of each child. He said to them, "Come out of the river a~ once if the water reaches the line."
