I am writing to tell you my opinions on whether middle school students can take mobile phones into school. In our school, it is a rule that mobile phones are strictly forbidden and if we break the rule, we will be punished.Actually, taking mobile phones into school is sometimes beneficial. Students can easily search the Internet for some useful materials and it is one of the quickest ways to exchange information. However, taking mobile phones into school can also bring bad effects. It is easy for middle school students to be addicted to games on phones, which undoubtedly affects their study and eyesight.As far as I am concerned, I agree that it is not suitable for middle school students to have cellphones, especially at school.
