With the development of science and technology, almost every college student has his or her own mobile phone, but not every student uses mobile phone to study, some students are addicted to mobile phone games and videos, which wastes their study time. First of all, the popularity of mobile phones is beneficial, it makes our life more convenient, and it also makes it easier for college students to acquire knowledge, but mobile phones also have its other side. Nowadays, more and more mobile phone and video software have approached the life of college students. Every college student will contact some games and video software more or less, but some people are addicted to these software, wasting their time. For this phenomenon, firstly, I think we should let these addicted students realize their mistakes and let them know their purpose of coming to college clearly. Secondly, we need to help them stay away from mobile phone entertainment software for a period of time. Finally, we should supervise them in case they won't be addicted to mobile phone again. In a word, mobile phones have both advantages and disadvantages for us, we need to control ourselves to use mobile phones reasonably.
