The Internet is very important. It makes our life rich and colorful. But every coin has two sides. It does harm for our eyesight if we spend too much time on it.

　　I hope that the headmaster and teachers should often tell us how to make use of Internet correctly.

　　What"s more, we should stay away from the unhealthy website. It is very harmful for us.

【参考译文】

　　因特网很重要，它使我们的生活丰富多彩。但是每一个事物都有两个方面。如果我们长时间的上网，这对我们的视力不好。

　　我希望校长和老师应该经常告诉我们如何正确使用因特网。

　　另外，我们应该远离不健康的网站，它对我们危害太大了。
