Can We Use The Cell Phone in School?

When I was in high school, there were many school's rules, and one of them is "no cell phone in school". Being a college student it is very strange for us, why does the high school have this rule. The high school's teachers would say if students had to make a phone call, they can use the phone in the teacher's offices. In my opinion, students can use the cell phone no matter in high schools or other places. The reason why I think that is because sometimes we must meet some emergency, and we have to use the cell phone immediately. But some people say that if students can carry the cell phone to schools, they will not concentrate on class. They are many functions of the cell phone, and students can surf the Internet, or do other things except studying.
     Although this issue is argued for many years, we still cannot find the consensus. Some people say "no", but I have other view of this issue. I think the cell phone not only can make a call but also do other things. We can check the Internet to watch the news or record our school life. Nowadays, there are many bullying in schools, I think a cell phone can help others or ourselves. Many victims of bullying are afraid of talking to teachers or parents. We found lots of bullies from the Internet, and finally people actually realize bullying exist very long time. Owing to the cell phone, people can send the pictures or videos to the Internet.
     Some teachers say if students can bring cell phone to schools, it will disturb their teaching, but I think this situation can be handled easily. Teachers can ask students close their cell phone in class. If someone is against this rule, the teacher can confiscate students' cell phone. I think this way is fair no matter to students or teachers. I think using the cell phone can let me feel safe. I remembered when I was in high school, my mother got a phone call from the scam, and the sharper told my mom that they already kidnapped me. Fortunately, my mom is smart, she called me before she gave money to the sharper.
    To sum up, I think students can use the cell phone in schools but not in class. If we meet some emergency, we can use the cell phone immediately. Our parents can find us easily through the cell phone. After all the public security is not very good in Taiwan.(424)
