Classes are over at 3：50p.m,but we don't always go home at that time. Many of us stay at school. Some do their homework, some work or play in the school. We clean our classrooms, work in the school garden, or go to the playground to play ball games. Today is the first day of the school week. We usually go to Mr Lin's home. He is an eighty -year -old man. We read newspapers to him, talk to him, wash his clothes and clean his room. Mr Lin likes to be with us. We feel happy, too, because we can help others.
