Technology (Fluency exercise #2)

Have you ever sent messages to your friend with your cell phone? It takes a very short time to deliver it to your friends and it is easy, also. It is so convenient that many people use cell phones for connecting with their friends. However, it causes some problems for teenagers who are in adolescence. Adolescence is the period that many teenagers cannot control themselves in. Because of that, it happens that many teenagers send messages to their friends whenever they want, even in class. So, it affects their school life and regular life in a negative way. Sometimes, they cannot attend class because they had chatted with messages with their friends until the morning. In addition, the cell phone causes an electron wave that causes people to have low eyesight. Actually, many teenagers have glasses because of the electron wave. These are some problems about using cell phones and sending messages.
