Zhang Ming is a student. He often goes to school on foot. This morning he went to school by bus because he got up late. Li Dong is Zhang Peng's classmate and he did not go to school. He went swimming last weekend and had a cold. The doctor asked him to take some medicine and stay in bed. So he has to stay at home for a few days. After school, Zhang Peng and his classmates are going to buy some flowers and visit him.
