正文：
Online games bring serious harm to teenagers. So I advise friends: "don't indulge in online games."
网络游戏给青少年带来的严重危害。所以我奉劝朋友：“不要沉迷于网络游戏。”
Once you become addicted to online games, you can't control yourself. When you don't surf the Internet, you always want to surf the Internet. I can't control the time of surfing the Internet. I think about things, plots and characters of online games all day. And it will make people depressed, so that physical and mental health have serious harm. In a word, "indulging in online games is harmful but not beneficial to you."
网络游戏一旦上瘾，你就会控制不住自己，不上网时还一直想着上网。无法控制上网的时间，整天想着网络游戏的事情，情节和人物。而且会让人委靡不振，让身心和健康得到严重的危害。总之一句“沉迷网络游戏只对自己有害而无利。”
Here I still want to advise our young people "do not indulge in online games", it will bring infinite harm to themselves. ". We are the pillars of the future world. Let's be teenagers in a new era and make good use of the Internet to bring us endless knowledge.
