There has some strict rules in our school."Don't take the cellphone into the school,or it will be confiscated.""Don't wear slippers in school.""Girls hair must be tied up..."These rules set so as to rule us behavior.But are them really good to our study?No really.As far as I'm concerned,school's rules should do good to students' study but not to rule us firmly.Teachers' can set rules which could make us pleased to study,not to rule our behaviour.（仅供参考）
