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。
