阅读短文，从A-G七个选项中选出最佳五项填入文中空白处，有两项多余。
Dear Tom,
Many school rules seem strict, but they are designed to protect and improve you.
1 Being punctual is a basic respect for teachers and your whole class.
2 Phones will greatly distract your study and stop you from concentrating in class.
3 Uniforms help create equal school culture and strengthen school spirit.
Instead of only focusing on strict rules, you can notice your allowed activities. 4 You can enjoy leisure time after finishing homework, and you can also go out with friends on weekends.
It is not easy to stick to rules all the time, but rules keep society running well. 5 Remember the old saying: No rules, no order!
Yours,
Dr Know

4.C
5.E
多余干扰项：F、G
逐题解析 & 语法考点
1.第1空 选A
核心语法：must（主观强制规定），同义改写原文不准迟到的校规，后文衔接迟到礼仪的意义，逻辑通顺。
2.第2空 选D
核心语法：mustn’t（明令禁止），对应课堂禁用手机的校规；干扰项G只是善意建议，并非硬性校规，不符合段落主题，排除。
3.第3空 选B
核心语法：have to（客观要求的必须），校服是学校客观规定，后文正好解释校服的作用；干扰项F和原文规则完全相反，直接排除。
4.第4空 选C
核心语法：can（表示许可），本段全部介绍学生可以做的事情，在家使用手机是原文规则的同义转述，和后文休闲活动并列。
5.第5空 选E
承接上文规则的价值，升华文章主旨，自然引出结尾谚语，结构完整。
核心语法复盘
- mustn’t：强调校规明令禁止的行为
- have to：外界（学校）要求的客观义务
- can：代表被许可做的事情
- 难点区分：should（建议） ≠ must/mustn’t（强制规定）
