作为一名学生，下面列出的建议非常好。
1.经常使用电脑，每天只需短时间。在电脑前花很长时间或不受控制对你的身体不好。
2.需要时使用电脑。老师可能会要求你查找一些有用的信息，或者一些问题被你的作业所困扰，这时电脑将是一个很好的帮手。
3.避免更多的游戏、音乐、电影和聊天。这会压缩学习时间，还会在你和家人之间产生一些问题。
当然，如果你不走得太远，一些必要的放松可能对你的成长有好处。
总之，经常控制自己，正确使用电脑将对你的学习有很大帮助。
写作思路：可以写加强自我监督，不浏览不良信息；不沉溺网络、热衷于游戏；将合理利用网络资源与提高学习有机结合等等。
正文：
Strengthen self-monitoring, do not browse bad information. The Internet is a double-edged sword. We teenagers are in the growth stage, with immature psychology and great plasticity in mind. If we are corroded by bad ideas, or even deeply poisoned and unable to extricate ourselves, it will lead to crime and loss of youth.
加强自我监督，不浏览不良信息。网络是一把双刃剑，我们青少年正处于成长阶段，心理尚未成熟，思想上还有很大的可塑性，如果被不良思想腐蚀，甚至深受毒害、不能自拔那将引向罪恶，失去青春。
Not addicted to the network, keen on the game. Nowadays, there are so many online games, such as online chatting, chess and cards, film and television and so on. If we don't control ourselves and spend too much time and energy on these aspects, we will distract our attention and affect our study at a small level, and damage our physical and mental health at a large level. Therefore, we should be moderate and spend more time on study.
不沉溺网络、热衷于游戏。如今网络游戏铺天盖地，网上聊天、棋牌、影视等娱乐方式五花八门。如果不加以自控，在这些方面花过多的时间和精力，小则分散注意、影响学习，大则损害身心健康。因此要做到有所节制，将更多时间花于学习。
We should combine the rational use of network resources with the improvement of learning. We should realize that the network is a vast and rich platform for learning resources, and combine the rational use of the network with the improvement of learning efficiency.
将合理利用网络资源与提高学习有机结合。我们要认识到网络是一个博大丰富的学习资源平台，将合理利用网络与提高学习效率结合起来。
