2. 词数 80 左右,开头已给出,不计入总词数;
3. 文中不能出现真实姓名及学校名称。

Dear Mike,
I'd like to introduce our school rules to you.




Yours,
Li Hua

First, we mustn't be late for class in the classroom. We need to listen to teachers carefully, be polite to classmates and take good care of our own things. Second, in the lab, we can't bring food or drinks there, and we mustn't enter it alone. We have to clean the lab twice a week. Third, in the dining hall, we should wait in line, and we can't speak loudly or throw food everywhere. These rules help us have a good school environment.

这是一篇介绍校规的应用文写作，写作可按以下步骤完成：1. 按照思维导图给出的教室、实验室、餐厅三个场景依次展开内容，覆盖所有提示要点；2. 使用七年级所学的must/have to、Don't引导的祈使句表达规则，语言简单贴合对应年级的知识范围；3. 适当添加衔接语句，控制总词数在80左右，符合题目要求，不出现真实姓名和学校相关信息。
