Mobile phones in schools.
Do I need a student at the school cell phone? There are so many different opinions, I personally believe that the mobile phone is necessary.
First of all cell phones give us an opportunity to keep in touch with friends and family in any time. It is especially important for children, as parents need to know that their baby is fine.
Besides, modern mobile phones are multi-function: they provide access to the Internet, which is also necessary in some situations. They also can be used to store any relevant information, especially when you do not pen and paper.
On the other hand, mobile phones provoke a range of problems. They are very distracting teachers and students from work. In addition, the phone is very harmful to health.
In my opinion at the present time mobile phones are an integral part of life of any person. I personally need it every day, though I’m aware of its deleterious influence on my health. I try to find the happy mean.
