《2025年暑假作业知识出版社七年级合订本》

Dear Linda,
How's everything going? I'm glad to share my new school rules with you.We must finish our homework on time. We can't bring mobile phones to school. We are supposed to get about 9 hours' sleep a day. We have to read a good book once a week. It's required that we do exercise for an hour every day. For safety, we must not fight with others and we should not run in the hallway. In my opinion, these rules are helpful. They can help us develop good habits and keep us safe. So I will try my best to follow them.
What about your school rules? Please write to me soon.
Yours,
Li Hua

We must finish our homework on time. We can't bring mobile phones to school. We had better get about 9 hours' sleep a day. We must read a good book once a week. Doing exercise is also important. We must do exercise for an hour a day. We must keep safe first. We must not fight with each other and never go swimming alone. I think these school rules are good for us. We must follow them.
