Now, let me tell you some of my rules. At school , first , we can't be late for school. Besides , we have to wear school uniform. What's more, we can't run in the hallway, because it keeps us safe. Finally, we mustn't eat in class, because we must focus on learning. At home , I have more rules! I have to finish homework first. I must clean my bedroom every day. I think it's helpful because it keeps room tidy. And I can't watch TV on weekdays. I hate this rule because I love watching TV. All in all , it's hard to follow all these rules, but they can help me to be a better person. As the saying goes, no rules, no order. ) ◆拓展知识 公共场所规则： No smoking.（禁止吸烟。） Keep off the grass.（勿践踏草坪。） 语法练习答案 祈使句 一、 1. Don't be 2. Don't make 3. Open 4. Don't talk; read 5. Don't leave 6. Look 7.
