should mobile phones be prohibited from using in public? With the development of communication and society, the mobile phone has become a necessary thing for our daily life. We usually use it to talk to our parents, chat with our friends on mobile QQ or buy something online. It seems to be that we can't leave it, no matter where we go and what time. But is that really true? We can't leave it, so we can use it anywhere and anytime. In fact , I think mobile phones should be prohibited from using in public, such as classroom, working place and restaurant. Inmaging that you were doing a hard research in the classroom while someone were talking with her friend on mobile phone loudly , you might be crazy and want to let her go out. Another example, you and your familiars eat donnie in a restaurant quietly. Everything seems wonderful.Suddenly , a guest in this restaurant answer a phone. He is so glad that his voice is much louder. Then the better atmosphere is destroyed. You may feel not happy, but you can't say anything about it, because there is no law, which required no phone in the restaurant. It's no doubled that mobile phone is of great help for our life and we can't leave it completely in our daily life. But we should use them appropriately and avoid disturbing others' peace and quiet, for example, we can close it or set to silent when we are in classroom or in public.
