【六、单元主题模仿写作】

题目：My School Rules

范文：** At my school, we have many rules, but they help us learn better. First, we can’t bring mobile phones to class. We must turn them off and keep them in our lockers. Second, we have to wear the school uniform every day. It builds school spirit and makes us equal. Third, we can’t eat snacks in class, but we can drink water. Also, we must be on time and show respect to teachers.

Some students think these rules are strict, but I understand they create order. Without rules, our classroom would be noisy and messy. As Dr Know says, “Rules can help to make the world better.” So, I follow the rules and try to be a responsible student.

写作要点提示：

①使用本单元情态动词（can’t, must, have to）

②结合具体规则（手机、校服、零食、守时）

③ 表达对规则的理解（引用“No rules, no order”）

④ 结构清晰：规则列举 + 个人观点 + 总结升华
