假如你是李华,是一名中学生，随着社会的发展,刷短视频已成为中小学生甚至成年人的喜好。有人说刷短视频,可以学习到很多书本上没有的知识，有些短视频很专业，有人说刷短视频对中小学生危害很大，容易让中小学生沉迷而且使他们失去耐心，对中小学生的性格形成也不利。请你用英语给某中学英语报社写一篇短文稿,谈谈你对中小学生刷短视频的利与弊，短文内容自由发挥,合理即可。
参考范文：
Now with the develpment of society , more and more students have smartphones , they often use the smartphone to watch short videos, such as Kuaishou , Douyin and so on. Many families have to face the problem: how to control the students to use the smartphones correctly.
In my opinion, students sometimes watch the short videos they maybe learn something useful . But watching short videos often is bad for them. First , it is bad for their eyes. Second, it effects their study. Third, some short videos are not good for students. After that, if students spend most free time on short videos, they will have no time to do sports, it is bad for their body. Students should do more outdoor sports. As students, we should spend most time on study and sports to help achieve study success.
So all the parents should make a family rule to guide their students to use smartphones in a proper way.
