【答案】Mobile phones are becoming more and more popular among the students nowadays.However，mobile phones also bring more problems to students.For example，they do not like to eat food in the school canteen，order takeout at will，and buy online on mobile phones，and spend more money，which exceeds the living expenses given by parents，and also brings a large economic burden to every family.Sometimes，they don't sleep at night to stay up late playing games，sleepy in class during the day，seriously affect the learning，and students even bring the mobile phone to class，class time，take up learning time，affect the teacher's lecture，also affect the students around learning state，seriously affect the normal teaching order，in the long run，small affect your eyesight，big will affect the teaching quality of the school and students learning atmosphere.As a middle school student，in view of the above problems，I suggest that you do not play mobile phone for a long time，to complete the learning task first，in the absence of any schoolwork can play mobile phone.Do not play the mobile phone when walking or riding a bike，long-term addicted to mobile phone games，will have a great harm to your eyesight and physical health，especially on the road to look down at the mobile phone，there is a life danger.Personally，I think that middle school students had better not bring mobile phones into the campus，there is a public phone in the school，and you can contact with their parents，in case of emergency.If the weekend or holiday also want the correct use of mobile phone to help us study，rather than blindly addicted to online games，the learning lessons behind，in the end will destroy your future.
