阅读理解。 Son's Help Mr. Lang worked in a factory. As a driver, he was busy but he was paid much. His wife was an able woman and did all the housework. When he came back, she took good care of him and he never did anything at home. So he had enough time when he had a holiday. A few friends of his liked gambling (赌博) and he learned it soon. So he was interested in it and hardly forgot anything except gambling. He lost all his money and later he began to sell the television, watches and so on. His wife told him not to do it but he didn't listen to her. She had to tell the police. He and his friends were punished for it. And he was hardly sent away.
