     Tim is a 16-year-old boy who studies in a high school .His parents tell him to study hard and they do everything for him. They wake him up at 6:00 a.m. and after breakfast his father takes him to school by car. As soon as the young man comes home from school, the supper is ready. Of course, he never does chores(杂物). Once, Tim's father would go to London on business for a year. Before leaving, he told his wife to look after their son well. The woman had to get up earlier and did all what her husband did before. Two months later, she was so tired that she was ill. The young man got into trouble at once. He couldn't do housework. He didn't know where to get on the bus.

     Yesterday Tim's mother found his shoes were worn out and told him to buy a new pair. But he didn't know how to choose right shoes. The woman had a sigh(叹息）,gave him a shoe pattern(鞋样)and told him to buy shoes himself. With a policeman's help, he found a shop. The shopkeeper brought some shoes and asked him to choose. When he was trying on pair, suddenly he remembered something and took them off. The man was surprised and asked, “What's the matter?”

“I'm sorry. I've left my shoe pattern at home.”
