Different people have varied opinions towards it. As far as I'm concerned, students can bring phones to school as long as proper rules are made. There is no denying that smartphones act as useful learning tools in daily study. For example, whenever I come across unfamiliar English words, I can look them up immediately. Moreover, using phones wisely at school helps us build self-discipline, which is a valuable skill benefiting us lifelong. In closing, mobile phones will be helpful instead of troublesome if we use them correctly. Thus, we students should be given this chance to improve our self-control. Thank You $
