Yesterday,our class had a discussion about whether students should have mobile phones.70 percents of us thought that we should have mobile phones.They thought Imobile phones were necessary when we havet to contact our parents or ask our classmates about some problems.About 30 percents of us disagree.They thought using mobile phones to send messages and play games was a waste of time and money.In my opinion,students should have mobile phones.But we should use it in a right way.Don't waste too much time on it.
