In many countries schools have problems with student behaviour,explain the reason and selution.
作文：
Nowaday,there is a growing arguement about problem with student behaviour in many countries' school which influence students' academic performance negatively.In my opinion,there are several reasons why these things happen.
First and forecast,inadequate or unsuitable school rules generate problems of student behaviour.Schools are the place where students have access to formal education,so that schools have the responsibility to regulate student behaviour in order to facilitate their study.If the schools do not establish enough rules or rules can not be adaptted by most students,their behaviour may not be regulated properly and at the same time do something wrong.
In addition,teachers in school are still a primary factors for student behaviour.Teachers need to educate not only knowledge but also various characteristics to cultivate students' proper behaviour.If the teachers are not able to teach students how to control themselves with enougrh patience,it is difficult to control what they do only by restrictive rules.
Finally,students themselves are also responsible for their own behaviour.For many students are the only child in families,they lack essential self-control to regulate their behaviour.Moreover,young students are innocent and curious,so that they may not distinguish right from wrong.Due to their curiority,they will probably do something incorrect and even criminal which seriously affects their future development.
From above discussion,we can see that it is necessary to take suitable steps to solve this problem.I believe that to consititute proper school rules is undeniable.Still,students themselves need to be educated the importance of selt-discipline too.
