I'm Li Lin. Zhang Ming is my good friend. He's younger than me. But he's taller than me. We usually play football on the weekend. But last Saturday, he was at home. Because his mother had a cold. Zhang Ming cooked breakfast at 7: 00. After breakfast, he washed the dishes and cleaned the room. In the afternoon, he took his mother to see the doctor. In the evening, he did homework. Zhang Ming was so tired. But his mother was very happy, "Zhang Ming, you're helpful. You're a good boy!"
