Many years ago, cellphone was not allowed to be brought in the classroom, but now cellphone has been part of people's live and students can use it anytime. My mother bought me a cellphone, so I could keep in touch with her, but she was worried about me a lot. Since I had the cellphone, I always wanted to play it, even the time I was having class. Cellphone distracted my attention on study. I realized it changed my life and I must used it in the proper way. So I turned off my cellphone when I was having class, and I also controlled myself not to play it when I was doing homework. Now I get used to the cellphone.
