Ⅰ 中學生上學帶手機有什麼壞處，我們要參加辯論，答案要靠譜。最好用英語
1、學生多了一份牽掛，因為他要照顧手機，這么小的孩子就開始分心了。
2、會嚴重分散學生的精力，影響學習！每個人的自控力是不一樣的。開始買手機的目的可能是方便和父母的聯系，可事實上孩子用於聯系父母的有多少次？據查，孩子用手機，最多方面是：聯系同學、發信息、看小說、玩游戲、、上網、聊QQ等。可以說，成績好的大部分同學大多是沒有手機的。學生可以直接在教室里隨時通過手機進行QQ聊天、網頁瀏覽、閱讀黃色信息和撥打不良聲訊台。據調查，持有手機的學生90%以上都收發過很露骨的黃色簡訊。如果用手機進行空中下載，20元人民幣就可以大約下載50本（每本500頁）流量的小說；如果進行QQ聊天的話，20元人民幣按現在的標准可以包70M的流量，說的簡單一點，每天從早到晚上再到深夜無時無刻都進行QQ聊天也用不完。目前，手機已成為學生精神污染的主要來源，在給通訊部門帶來豐厚利潤的同時，也給學生的心理健康帶來了極大的副作用，其後果是非常嚴重的，難怪美國的中小學是禁止學生佩帶手機的。
3、因丟失產生連鎖反應。由於它體積小，容易丟失。校園里每年發生的多起手機丟失事件，出於種種原因，即使上報介入追查也沒個結果，家長的埋怨和責怪，學校教學精力的分散，學生的學習心情大受影響！因為丟失手機，同學之間的猜疑，曾引起打架斗毆事件！
4、遭受騷擾和侵害。總有些人會通過各種途徑弄到孩子的電話號碼。騷擾、威脅，稍不留神就中道了。同時，也容易遇到搶劫。
5、考試中的作弊，不少孩子發簡訊都可以盲打。防不勝防。
6、為早戀提供了優質的紐帶。
7、使用手機對身體健康有不良影響。盡管廠商在推銷手機時宣稱手機是如何環保和防幅射，稍有知識的人都知道手機是有幅射性的。中學生處於長身體時期，大腦中吸收的幅射比成年人高出5%已有實踐證明
