Old Smith is very fat. He always tells his son Little Smith that he wants to be thin. But Old Smith never does any exercise. He often eats hamburgers and meat. Sometimes he watches TV and eats ice cream all day long. And he gets up at 10 o'clock every day. One day, Little Smith asks Old Smith, "Why do you never do any exercise? You will always be so fat." Old Smith answers, "Why? I do sit-ups (仰卧起坐) every morning and every night! Every morning I get  'up' and every night I lie 'down'. "

I'm Shanshan. I'm eleven years old. I'll tell you something about my weekend. On Saturday morning, I always do my homework. Then I often read books and draw pictures. I never play computer games. I sometimes play chess with my friend Dongdong in the afternoon.

On Sunday morning, I always help my mother do the housework. And I often go to the supermarket with her. Then I'll help her do the cooking. In the afternoon, I sometimes play football with my friends. I sometimes go to the cinema in the evening. But I never go swimming on Sunday.
