While they are useful tools, they often do more harm than good in a school setting. Admittedly, phones allow students to contact parents in emergencies and access learning apps. However, like Pandora's box, they bring distractions. Many students can easily feel distracted by games or social media during class, which is harmful to their academic performance. Therefore, I believe schools should limit phone use on campus. A focused learning environment benefits everyone. 假定你是李华，近日你所在班级围绕学生是否可以携带手机进校园展开了一场辩论赛。 请给校英文报投稿发表你对此的观点，内容包括：1. 你的观点；2. 论据及理由。 注意：词数80左右； $
