Mobile phones are not necessary for school students.

　　拿出我的小瓶盖。OK，那我就开始了。

　　我们可以多练几次，因为我本来是四点半之前有空，现在四点半之后也有空了，我原本要做的事情取消了，因为老师有事情，所以我们可以练习久一点。电量 54，希望大会可以充一下电。OK，那我就开始了。

　　Today I hold a view that mobile phones are necessary for school students. Because with the help of the mobile phone, they can know how to connect with each other. And communication between friends is very important. They can enhance their relationship with each other. Also, they can use the mobile phone to know the world better and get more information.

　　Three two one go. Hi everyone. My point is mobile phones are not necessary for school students. We can see the mobile phone can be a distraction for these people. Also, it can make these people lose the creativity and the ability of thinking.

　　有病了，我先把嘴里的锅巴吃完。那我来了。

　　In the digital time, everyone has their mobile phone. So I think it's not possible to restrict the use of mobile phones for teenagers. Also, with the help of mobile phones, they can communicate with their friends and know more knowledge. I think it has pros, and I think its pros are much more than cons.

　　All right, we know that mobile phones can be a good choice for us. But if teenagers really depend on their mobile phones, it will cause some problems. They will lose something, like their creativity and critical thinking.

　　Yes, we can't restrict the use of mobile phones just because they have these advantages. I think everything has both advantages and disadvantages. The most important thing is to make rules for teenagers to develop their ability to control themselves and to prioritize the most important things.

　　However, we can see that not everyone has strong self - control. So it can be bad for these people and make them lose the love for learning and just want to enjoy a comfortable life.

　　Just because not everyone has self - control, we need to develop this ability at a very early time. If students get their first mobile phone at college time, they may even waste their time in college.

　　Middle school students' most important task is to prepare for their college entrance examination. So the time they can focus on learning and think about language knowledge is limited. If most students just play with their mobile phones, it will create a bad atmosphere for other students who want to study.
