About "What are the advantages and disadvantages of middle school students bringing mobile phones into campus?" I support the debate.

Mine is the opposing side. Please find out some shortcomings. This is my debate draft:

First, it affects class. In fact, it is not the mobile phone that affects the class, but the people. As long as the mobile phone is well managed, it will not affect it. Of course, the other party may tell you that middle school students have poor self-control ability and want to play mobile phones in class. For example, everyone likes playing football, and some students want to play football in class. Can we say that playing football does more harm than good?

Second, it affects rest. In fact, people's rest time is certain. There are all kinds of games on the mobile phone, which can relieve boredom during the rest time, and some games can also exercise their thinking. Of course, the other party may mention that excessive games do more harm than good to people. At this time, you should pay attention to the degree of the game, just like the degree of playing football. We may be crazy about playing football, but we can't say that the advantages of playing football outweigh the disadvantages.

Third, spam. I don't have a mobile phone yet, so I'm not sure what junk information there is, but I believe parents will not relax their discipline on their children. If garbage harms children's physical and mental health, they will take certain measures to control it, so under the supervision of parents, I don't think mobile phones will do much harm to children. However, it should be noted that parental supervision must be strong enough, otherwise it may be passive.

Fourth, the wind of comparison. Comparison is a psychological phenomenon. Even if there is no mobile phone, there may be a trend of comparison, and mobile phones are not the inevitable reason for comparison. Some students also like to wear some beautiful clothes. Can we say that beautiful clothes do more harm than good?

Fifth, it causes economic burden to family members. Please limit the use of mobile phones to students who already have mobile phones, because students without mobile phones can't even talk about using mobile phones together, and there is no need to talk about the influence of mobile phones on them. Students who can use mobile phones will definitely have more money at home, so there is no financial burden.

Sixth, there are hidden dangers in personal safety. What are the causes of personal safety hazards? It is that the security measures in the school are not strict enough or the criminals are too powerful. How can mobile phones become the cause of security risks? If a student carries a lot of money and is taken away by criminals, can we say that money does more harm than good to a student?

Seventh, students have poor self-control ability. This is actually a difficult problem to solve, but it should be noted that school activities are not only completed by students. Teachers at school will be strict with students, which is enough to make up for the lack of self-control.

Eighth, parents can check their children's mobile phone bills to see if they have more records of contacting their parents or classmates. Mostly the latter.

Students use mobile phones for three purposes: sending and receiving text messages, playing games and surfing the Internet. More than 70% of students no longer use mobile phones as a tool to communicate with people, but "mini" computers that can send and receive information, play games, surf the Internet, listen to songs and send and receive pictures like computers. Compared with desktop computers or notebook computers, mobile phones certainly have many advantages. Some students feel that contact is convenient, easy to use and very light. Whether students own or use mobile phones, texting with mobile phones has become the main use of mobile phones. Even the students who make phone calls mainly chat and ask homework, and have little contact with their families. Many students waste their time on texting. You come and go, endlessly, time quietly passes through these fingers, and the phone bill is gradually exhausted unconsciously. Some students even send text messages in class, which wastes their studies and affects classroom discipline, making teachers stop lecturing and wasting precious time on such boring things. What's more, using mobile phones as a tool for cheating in exams.
