网络有许多害处:1、伤身体,长时间坐在电脑前,对智力、视力损害大,我身边有不少这样的例子,有同学一玩就是十几个小时,甚至几天几夜,整天无精打采,脸色灰白!2、整天脑子里想的都是游戏、上网、聊天,根本就没心做其他事情,什么意志都没了。3、花钱多。去上网, 三下五除二花完钱还想上,就去骗、偷、抢……太容易犯罪了。 The network has many harmful effects: 1. Injuring the body, sitting in front of a computer for a long time, has great damage to intelligence and vision. There are many such examples around me. There are more than ten hours or even days and nights for students to play. The day was listless and his face was pale! 2. All thoughts in the brain were games, Internet surfing, and chat. They simply didn’t mind doing other things, and they lost all their will. 3, spend more money. Going to the Internet, trying to cheat, steal, and rob... if you want to spend money on money and money, it’s too easy to commit crimes.
