Nowadays, more and more college students are addicted to online games. Those games may be funny and exciting, but are very harmful to those addicts. In my opinion, there are many disadvantages of game addiction.Firstly, online games take up a lot of players’ time for study. Many of the addicts found themselves forced to drop out of school for poor academic performance. Secondly, addicts tend to isolate themselves from the reality. What’s worse , indulging in the virtual world for a long time, they are more liable to suffer mental problem and physical collapse. Thirdly , players are exposed to too much violent and unhealthy material, which is definitely harmful to their growth. In short,I cannot see any benefits from online games.Study should be the primary concern of college students. Therefore,I do hope they can step away from online games. mental [mentl] adj. 精神的，脑力的，精神错乱的 isolate [aisəleit] vt. 隔离，使孤立 performance [pəfɔ:məns] n. 表演，表现; 履行，实行 addiction [ədikʃən] n. 沉溺，上瘾 academic [.ækədemik] adj. 学术的，学院的，理论的 collapse [kəlæps] n. 崩溃，倒塌，暴跌 primary [praiməri] adj. 主要的，初期的，根本的，初等教育的 unhealthy [ʌnhelθi] adj. 不健康的，不卫生的，病态的，危险的 exposed [ikspəuzd] adj. 暴露的，无掩蔽的，暴露于风雨中的 v. 暴露 violent [vaiələnt] adj. 暴力的，猛烈的，极端的 （编辑：何莹莹）
