写作思路：针对于中小学生来说，不建议将手机带入校园，可以从将手机带入学校后会给学生带来那些危害来表述。
I don't think primary and secondary school students can bring mobile phones into the campus.
我认为中小学生不可以将手机带入校园。
School is a place to learn. Students' self-control is a little poor, can not help the temptation of mobile phones, immersed in the virtual world, forget the evening, leading to worse academic performance. If you forget to mute, it will affect not only the individual, but also the classroom discipline. Looking at a cell phone for a long time can also reduce eyesight.
学校是学习的地方。学生的自制力稍微差些，会禁不起手机的诱惑，沉浸在虚拟世界中，忘记了今夕何夕，导致学习成绩越来越差。如果忘记静音，来电话时不仅影响个人，还影响课堂纪律。长时间看手机也会使视力下降。
Students are the future flowers of the motherland, the hope of the future, so for the better growth of children, I hope students can not bring mobile phones to school.
学生是祖国未来的花朵，未来的希望，所以为了孩子更好的成长，我希望同学们不能带手机到学校。
In fact, if students use mobile phones in right ways, mobile phones will help us, such as we can use mobile phones to look up new words. But it can also bring some trouble. For example, many students use their mobiles to listen to music in class. They don’t listen to the teachers carefully. And many students send messages in class.
In my opinion, it’s not right to use mobile phones in school. We should try our best to use mobile phones in right ways.如今，越来越多的中学生拥有自己的手机。作为一名学生，我认为有一个手机是好的，因为手机可以提供很多方便。当学生在家里遇到麻烦或不在家时，他们可以给他们的父母发短信。事实上，如果学生用正确的方式使用手机，手机会帮助我们，比如我们可以用手机来查找新的单词。但它也可以带来一些麻烦。例如，许多学生在课堂上用手机收听音乐。他们不认真听老师讲课。和许多学生在课堂上发送消息。在我看来，在学校里使用手机是不正确的。我们应该尽力用正确的方式使用手机。本回答被网友采纳
