请为你们的学校图书馆写一个规定,不得少于6条，应包含以下要点：

1.保持安静 2.不准吃东西 3.不准听音乐 4.不准带包入内 5.不准吸烟 6.按时还书

要写短文 不要只写短语

1. keep quiet.
2. no food.
3. music is not allowed.
4. it's not permitted to bring bags into library.
5. no smoking.
6. please return the book in time.

可能的原因

一、还书时候操作有误，但是图书在架位上，你去找出来就能证明你还了（未办理还书手续不能进行下一次外借）

二、你把其他同学借的同种图书拿混了，还了其他人的书。

1:be keep quiet 2:no eating 3:no listening to music 4:not permitted to bring bags into library. 5:no smoking 6:return the book in time
