【正确答案】[范文]
   Poor student behaviour seems to be an increasingly widespread problem. Many experts insist that it is because of the students' individual qualities, but others advocate that it is not as simple as that. As I see it, domestic education, classmates in school and the whole education environment are factors that contribute to this problem.
   One very strong argument is that domestic education is not enough to regulate student behaviour. Many people are convinced that family is the first teacher for a child. A person's temperament forms when he or she is young and the families' behaviour can be learnt by children easily. Thus, if their families behave horribly, they may do so. One of the solutions to the problem lies with families who need to be more aware of the future consequences of spoiling their children. Perhaps parenting classes are needed to help them to raise their children to be considerate of others and responsible individuals.
   Another factor which must be taken into consideration is that school is also an environment for students to learn from each other. If a student always communicates and studies with his classmates, he can learn others' behaviours in a short time, including bad performance.
   Consequently, the school environment cannot be neglected. High quality elementary schools could be established that would support families more in terms of raising the next generation.
   Last but not least, the whole education environment of a nation is also crucial for student behaviour. Some students under great pressure may behave terribly. If the education department lays too heavy a burden on students, they may be stressed out, give up studying and thus do something harmful. To solve this problem, the government should publish some guidance for students' school work which specifies students' leaning objectives and make some changes to alleviate burdens on students.
   From the above views, I hold the opinion that the terrible behaviour of the students is not only the responsibility of themselves, but also of other factors including family, classmates and education environment.
