Hey lifei, well done . 

Although i personally do not fancy the structure of your essay(35553 or 3773), i find your essay easy to read and am also impressed by your extensive range of vocabularies .

here is a bit of my comments on your essay.

Poor student behavior seems to be an increasingly widespread problem. and I think that birth control tendency and the proliferation of violent online games are probably responsible for this.

(Perhaps you might make mention of your potential solutions. Well, purely my own preference. )

With the continuous acceleration of the life pace(this is fine but you might as well write like "with the accelerating pace of life, shorter...i guess. lol"), people tend to have smaller families with fewer children. This is most conspicuous in China in which most families are allowed to have only one child. With no siblings to share the love of parents, these "little emperors" are usually spoiled, and often act at their own will, with no regard of(for )the effects(what effects?) produced on others. When these "little emperors" deal with each other at school, dissensions and conflicts are predictable.

And there is also some detrimental effects in(on) the proliferation of online games with excessive violent contents. Teenagers are young ,and uncertain, and are vulnerable to the pornographic or violent games that are ubiquitous today. Young boys would imitate the powerful yet bad characters in the virtual games and become aggressive in the practical life(hmm real life?). 

(hmm,,i understand that you are talking about the proliferation of online games (violent contents),resulting in students' disruptive behaviors at school. I think, however , your topic sentence is inadequately clear.....  why do not you directly state that we should attribute students' undisciplined behaviors to online games or whatever..)

As far as I am concerned, the best way to tackle the bad behavior of children is to teach them to be considerate and thoughtful of those (who)around them. Ask them (people around them or ask themselves?)to keep quite in the airport waiting room, or hold the door open for those coming behind them(). Parents should teach their children to make their interests gradually wider(hmmm..) , until bit by bit, the walls of ego recede() and they become merged in the community life.

In terms of the pervasive online games, I do not think prohibiting young students from playing is feasible. But school teachers and parents should make concerted efforts to provide teenagers proper guidance, so as to teach them social etiquettes while enjoy the diversion and refreshment of online games.

Overall I think parents should treat children as "little adults"(polite and responsible) rather than "little emperors" waiting to be spoiled, and they should work together with school teachers to raise teenagers' awareness that they must treat people exactly the way they want to be treated.

well, i still feel that your essay needs a bit restructuring .......and keep your sentences more coherent ...(i will come back and read your essay next time... lol...)
