     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  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. After he came out of lockup(拘留所), he hated her

very much and the woman had to leave him.

      It was New Year's Day. Mr Lang didn't go to work. He felt lonely and wanted to gamble again.

He called his friends and they came soon. But they were afraid the police would come. He told his

fiveyearold son to go to find out if there were the policemen outside. They waited for a long time

and thought the police would not come and began to gamble. Suddenly opened the door and in came

a few policemen.

     "I saw there weren't any policemen outside, Daddy," said the boy, "so I went to the crossing and

asked some to come."
