Ⅰ 中学生上学带手机有什么坏处，我们要参加辩论，答案要靠谱。最好用英语
1、学生多了一份牵挂，因为他要照顾手机，这么小的孩子就开始分心了。
2、会严重分散学生的精力，影响学习！每个人的自控力是不一样的。开始买手机的目的可能是方便和父母的联系，可事实上孩子用于联系父母的有多少次？据查，孩子用手机，最多方面是：联系同学、发信息、看小说、玩游戏、、上网、聊QQ等。可以说，成绩好的大部分同学大多是没有手机的。学生可以直接在教室里随时通过手机进行QQ聊天、网页浏览、阅读黄色信息和拨打不良声讯台。据调查，持有手机的学生90%以上都收发过很露骨的黄色短信。如果用手机进行空中下载，20元人民币就可以大约下载50本（每本500页）流量的小说；如果进行QQ聊天的话，20元人民币按现在的标准可以包70M的流量，说的简单一点，每天从早到晚上再到深夜无时无刻都进行QQ聊天也用不完。目前，手机已成为学生精神污染的主要来源，在给通讯部门带来丰厚利润的同时，也给学生的心理健康带来了极大的副作用，其后果是非常严重的，难怪美国的中小学是禁止学生佩带手机的。
3、因丢失产生连锁反应。由于它体积小，容易丢失。校园里每年发生的多起手机丢失事件，出于种种原因，即使上报介入追查也没个结果，家长的埋怨和责怪，学校教学精力的分散，学生的学习心情大受影响！因为丢失手机，同学之间的猜疑，曾引起打架斗殴事件！
4、遭受骚扰和侵害。总有些人会通过各种途径弄到孩子的电话号码。骚扰、威胁，稍不留神就中道了。同时，也容易遇到抢劫。
5、考试中的作弊，不少孩子发短信都可以盲打。防不胜防。
6、为早恋提供了优质的纽带。
7、使用手机对身体健康有不良影响。尽管厂商在推销手机时宣称手机是如何环保和防幅射，稍有知识的人都知道手机是有幅射性的。中学生处于长身体时期，大脑中吸收的幅射比成年人高出5%已有实践证明
