1.I think parents should share some responsibility for this situation.
2.Parents give their children too much freedom and lack of time to communicate with them.
3.Therefore, parents and children have generation gap, especially for teenagers.
4.Most teenager lack of parental love and care, they may easily stray.
5.They will use another method to substitute parental love and care.
6.For example, they will try to smoking, stealing, drinking, drug abuse and so on.
7.They also want to attract parents 'attention.
8.We cannot blame them since teenage are too young and immature.
9.We should do our best to help them such as reeducate correct concept of parents and increase amount of social worker to help them easily, etc.
