There are many in our life. We should the rules. We must for the green light. We cross the road when the light is ted. It's very dangerous. And we mustn't on the road. We mustn't pick the flowers in the park. And we must keep the grass. We must quiet in the library or in the hospital. If we meet people, we should help them. We take good care of young children. We mustn't litter and spit everywhere. We should keep our environment(环境) and be polite to everybody.
