Can students buy mobile phones?

Students can buy mobile phones, but don't bring them into the campus for use.

The hazards of students bringing mobile phones into campus can be summarized as follows:

First, it affects children's health.

Long-term radiation of mobile phones is not good for students' physical development. Professor Gail, who studies human cranial nerves and cells at the University of London, wrote that the brain cells and DNA structures of normal mice showed signs of destruction after being exposed to radio waves with a frequency range similar to that of mobile phones for four hours. Studies have shown that when children use mobile phones, the radiation absorbed by their brains is 50% higher than that of adults. Liang Xuanmei, from Lanzhou Hospital of Integrated Traditional Chinese and Western Medicine, said that many teenagers are using mobile phones now, thinking that it has little impact on their health. In fact, teenagers' immune system is weaker than that of adults, so they are more susceptible to radiation. Facts have proved that cell phone radiation can damage the brain nerves of teenagers, causing headaches, memory loss and sleep disorders. Often playing mobile games and listening to mobile songs will also cause great damage to children's hearing.

Second, it affects children's mental health.

SMS provides a quick and simple modern way for people to exchange information and express their feelings. However, this is also a "grey zone" with lack of code of conduct and high confidentiality. While people enjoy free communication, human weaknesses such as lust indulgence and moral anomie are also revealed. Among them, the spread of unhealthy information is the most harmful. "Yellow jokes", which used to be mostly circulated among adults, were spread to minors through SMS. Seeing that many young hearts are polluted by this, they all suffer from no effective countermeasures. According to the survey, about 79% students said that they used it for "word flirting". 74% students send more than 10 messages every week, and 44% students send more than 20 messages. Shang, a judge of Haidian District Court in Beijing, pointed out that due to the strong concealment of short messages on mobile phones, it is not easy to be detected, and young students are exposed to pornographic information for a long time, which is easy to form psychologically unhealthy reading pleasure. Too many text messages can make people insane. If direct communication is replaced by mobile phone communication, it will make them unable to accept the differences between people and do not know how to respect others. Glenn Wilson, a psychologist at Royal College, University of London, UK, said that in 80 clinical experiments, the IQ of people who often send text messages at work will decrease by 10%, which is equivalent to not sleeping all day, and will only decrease by about 4% after smoking marijuana. Moreover, the content of short messages is generally unfiltered, and middle school students in the stage of "seemingly incomprehensible" are easily attracted by unhealthy content and go astray.

In addition, in school, it is easy for students to send short messages through mobile phones to spread incorrect public opinions and ideas. A student's misunderstanding of teachers and classmates will soon lead to many students' misunderstanding of teachers and classmates, which will not only affect unity, but also affect the healthy development of students' psychology and ultimately harm students.

A few students who are not interested in learning overuse mobile phones, making them the center of his life, and they can't live without them for a moment. Once they leave, their mood will change dramatically, becoming restless, depressed and depressed. Even normal conditions such as dead cell phone and weakened signal can cause their nervousness and anxiety, which are all manifestations of "cell phone poisoning syndrome". "Cell phone poisoning syndrome" will cause some harm to human function, such as arm numbness and decreased vision. More seriously, it may also cause autonomic nervous disorder, tension headache, anxiety and depression.

Third, it affects learning, others and the collective.

In the past, students skipped classes, skipped school and climbed over the wall to go out to the Internet cafe, and didn't come back at night. Now, students can chat directly on QQ, browse the web, read pornographic information, send text messages and play games in the classroom at any time. Where there is a mobile phone, there is the Internet.

High school students have poor self-control. When they are bored with the content of the class, they will play games, send text messages and even talk on their mobile phones, which will affect the classroom discipline and the quality of lectures. Some students don't turn off their phones in class, but turn their phones on vibration. Once a phone call comes in, they often want to answer it but dare not, and guess who it is, so they can't concentrate. This will not only affect yourself, but also affect and interfere with the study and life of others. This kind of lens is not uncommon: in class, the teacher is absorbed in talking, and several students bow their heads and send text messages below, having a good time; Other students in the dormitory need to rest, and a few students' mobile phone screens are flashing and chattering, which makes their roommates unable to sleep. The most terrible thing is to play under the covers at night, and teachers and classmates can't find it. They stay up late at night, sleep during the day, do nothing and copy their homework. Chatting by SMS is endless, and my academic performance has plummeted. Parents are worried, but students ignore it.

Fourth, corrupt the examination style and attack the style of study.

After students have mobile phones, some students spend most of their time and energy playing with them. They were at a loss when it came to the exam. When they take exams, they always have a dependence on mobile phones. They pinned their hopes on their mobile phones and used them to cheat, satisfying their vanity and cheating teachers and parents. Several parents said after the college entrance examination that my children's grades in school were still very good. Why didn't they even pass the exam? Why is the contrast so big? So blame the school, parents should know that it is ok to cheat at ordinary times, but it is impossible to cheat in the college entrance examination. Usually don't learn how to score in the college entrance examination? Students are becoming more and more proficient in cheating with mobile phones, such as tying headphones in their sleeves and pretending to think with their hands close to them during the exam. It is more convenient for girls, and some simply wear headphones on their ears and cover them with long hair, which is difficult for invigilators to find. In a senior three exam, 54 people took the exam in an examination room, and 38 people brought their mobile phones into the examination room. It's really scary. Using mobile phones can not only transmit answers, but also directly search for answers and compositions online, which not only seriously violates the examination rules and disrupts the fairness of normal examination competition, but also has a very bad influence on teachers and students. I often think that there is no good school spirit without a good examination style, and it is impossible to get good grades without a good study style. Not for grades, nor for the healthy growth of children. Why send children to Yunyang Middle School? So, I want to shout: welcome children, don't bring mobile phones.

Five, the trouble is easy to breed, and the accident is hard to prevent.

In the eyes of many students, branded mobile phones simply represent their own identity and status, which seems to make boys more chic and affectionate, and girls more gentle and beautiful. Because mobile phones are precious things and students' favorite, it will take a lot of energy and time to keep them, but they are still easy to be stolen by thieves, so the phenomenon of losing mobile phones on campus occurs from time to time, causing a lot of losses and troubles. There are too many cases in the first two months of freshman year. In addition, some students are youthful and can't stand the slightest injustice. Once there is a small contradiction, they will quickly gather social youth and classmates to fight through mobile phones, which will affect campus safety. At present, mobile phones have become the main source of students' mental pollution, which not only brings huge profits to the communication department, but also brings great side effects to the healthy growth of students. Like catalysts, they make middle school students mature quickly in a short time. Some students have to scrimp and save or ask their parents for money in order to pay the telephone bill, on the grounds that the school has to pay the information fee. A few girls have extensive contact with the outside of the school because of using mobile phones, thinking that the outside world is wonderful and longing for the outside life, which gives criminals in society an opportunity.

Sixth, the accomplice of love.

We should realize the harm of middle school students' "puppy love" to their study, and the mobile phone has actually become an accomplice of middle school students' "puppy love".

Mobile phones are the best tool and medium for their courtship. Passing love and talking about love through mobile phones breaks the limitation of time and space.

(2) Mobile phones are the "culprit" of their harassment. Some students' study life is calm and full. But as long as the mobile phone is in your hand (especially girls), suitors will flock to you, courtship messages will be overwhelming, and harassing calls will follow. Once so, she can't study with peace of mind, and the final result is to fall into the quagmire of "puppy love".

Seven, invasion of others' privacy

Nowadays, there are more and more functions of mobile phones, and many middle school students like to take photos with "camera" mobile phones as jokes; Even deliberately photographed the scene of the spoof and sent it online to promote uncivilized behavior, unconsciously infringing on the privacy rights of others. Even causing harm to others, these behaviors have caused anxiety and disgust among students, parents and teachers.

Eight, mobile phone trap

Nowadays, short messages that cheat people by winning prizes and lie about family accidents abound, adult jokes and bad short messages are hard to prevent, and divination, treachery and boring short messages are overwhelming. Students are immature, have no social experience, and are easily deceived or caught in the quagmire of bad text messages.

Facts have proved that once students have a mobile phone, they often regard calling friends and sending and receiving text messages as their "career". Not to mention wasting money, this kind of wasted time can't be recovered until the study plummets. Many examples show that sending a mobile phone is a disaster, and sending a mobile phone is a trouble; If you don't use your mobile phone for three years, it won't go bad; Use a mobile phone for three years and it will never get better; I'd rather buy a car to look after the children than send a mobile phone for convenience, and what I ask through the mobile phone is not true. If parents and friends want to know the situation, the telephone number of the class teacher has been published on the website, so you can contact them directly. Please ask students, parents and teachers to deeply understand the dangers of students using mobile phones and work together to create a better learning environment.
