【正确答案】Nowadays, teen violence has become a big issue in our society.
There are mainly three reasons for the teen violence. Troubled family can influence children and cause them to become easy to be violent because of their parents' frequent quarrels and fights. Secondly, disordered neighborhood encourages disordered behavior. Friendly relationship among these neighbors is generally lacking. Some teenagers even get involved with violent gangs. Media is another factor to cause teen violence. More and more violent movies, violent computer games, etc. come out to give teenager a wrong signal that violence is some kind of exciting and cool things to do.
To prevent teen violence, adults' behavior should be changed in both family and neighborhood and adults should understand and be close with teenagers. The government should be involved too, to limit the violent movies and computer games.
