答案：
答案:
School Rules
Welcome to our school, Mary. Here are some of our school rules. Let me tell you: We can arrive late for class. We can talk loudly in class. We have to be quiet in class, and we have to keep our class clean. When we meet the teachers on the way, we must greet them. We can eat or drink in the classroom. But we can eat outside. We can listen to music or play games in class, either. We can pick flowers or climb trees.
