The harm of mobile phone primary school composition 1
With the development of science, people's lives have made great progress, but those high technologies in life will also bring us harm. Cell phones, I think everyone knows. Mobile phones bring convenience to people's lives, but everything has advantages and disadvantages, and the harm brought by mobile phones even exceeds that of smoking. When people use mobile phones, they will send radio waves to the transmitting base station, and the human body will absorb these radio waves more or less. These radio waves are the radiation of mobile phones.
Generally speaking, mobile phones radiate less when they are in standby and more when they are talking. When the mobile phone number is dialed but not connected, the radiation is the largest, and the radiation amount is about three times that of standby. These radiations may change human tissues and adversely affect human health. Moreover, according to the Oriental Daily, a German study found for the first time that mobile phones may cause eye cancer, because researchers found that people who frequently use mobile phones are three times more likely to develop eye cancer than others. If this research result is further confirmed, it will inevitably lead to a large number of claims litigation.
The radiation released by mobile phones has long been accused of temporarily changing the function of brain cells, but there has been no evidence that these radiation will harm human health for a long time.
However, this study, led by Professor Shi Tangshou of the University of Essen in Germany, made an amazing discovery. When they investigated the eye cancer of uveal melanoma, they found that this kind of cancer was closely related to radiation. Mobile phone is an invisible killer, which has brought harm to people unconsciously, but now people can't live without it, so don't ignore its harm.
The harm of mobile phone in primary school composition II
One thing has been widely used in thousands of households: it can let people thousands of miles away see each other; Can let you know the news faster; It's convenient to pay when you buy things ... but it will also reduce your eyesight and make your career and studies barren. It is the "child" of modern parents and the "darling" of teenagers. Almost no one can turn a blind eye to it, it is a mobile phone.
Most modern adults watch mobile phones socially, and a few people catch up with a drama and watch news on their mobile phones. Originally, the mobile phone was just an entertainment electronic product, which also provided people with many conveniences and benefits. But many adults spend more time in contact with mobile phones than with children, which makes them unpalatable.
In life, "low-headed people" can be seen everywhere: some people walk to watch their mobile phones hit trees, some people fall into the water, some people take selfies and fall off cliffs ... When taking the bus, except some primary school students and grandparents, others standing or sitting are also watching their mobile phones. When I was eating out, I saw such a ridiculous scene: several people at the opposite table just synchronized, staring at the mobile phone with their heads down while eating, and no one wanted to put down their mobile phones. They are holding a mobile phone in their left hand and watching food and rice in their right hand ... I guess, if they don't pay attention to eating, can they taste rice? Maybe it tastes like chewing wax! I think this is ridiculous, but it is worth pondering: isn't it that mobile phones reduce people's intelligence and make people controlled by machines? Humans are highly intelligent animals, how can they be controlled by a brainless garbage? Kind of ironic.
Nowadays teenagers are addicted to surfing the Internet, watching mobile phones and playing games. Games are not only the entertainment of teenagers, but something that adults can't guess anyway-comparison. Seeing this, you may have questions. Don't worry, keep watching. You don't play online games with others or classmates, but you rarely queue up alone, do you? You don't want others to surpass you in any way, do you? Take some games as examples: What's the comparison between the glory of the king and the Fifth Personality? Compare positions; How does the mini world compare with my world? Compare vermicelli. A plain person can be an "emperor of Europe" or a "great god" in the game. Vanity can be satisfied here. In reality, he is just a nobody living in other people's world, but in the game, he can easily become a master in the virtual world. There was a time when I was obsessed with mobile games. Dad always shakes his head when he sees it. He thinks I will be disabled. My father, who is thousands of miles away, "ordered" my mother to accompany me to study after school every day and to accompany me to draw and practice calligraphy every week. Gradually I found happiness from my study, and my mobile phone seems to have been completely forgotten by me.
Teenagers play games to become the focus of attention in another virtual world, and they feel that their vanity has been satisfied. But virtuality is fake after all, and it doesn't really exist. It is better to put a lot of time and energy into real life.
Whether the advantages of mobile phones outweigh the disadvantages or the disadvantages outweigh the advantages depends on your own different views and understanding of mobile phones. Here, I want to say to all adults: "Every action that adults make inadvertently will be silently seen and remembered by children, and will continue to the next generation, and then the next generation ... without end. So, from now on, put down your mobile phone that never leaves your hand! "
Let me give you a suggestion, and quote a sentence from Hunan Satellite TV's public service advertisement: "Quit the addiction to mobile phones and spend more time with the people you love."

Do you know how many people are using mobile phones? According to statistics, by 20 years, the number of people using smart phones in the world has exceeded 2 billion, accounting for more than a quarter of the global population. An amazing data, but do you really know about mobile phones?
Once, I met a difficult problem. Five minutes passed, but I didn't come up with a solution. At this time, I was anxious like an ant on hot bricks-running around. Suddenly, the mobile phone on the desk caught my eye, and I quickly asked for advice from the mobile phone. Gee, how clever. I found a solution at once.
You have seen the charm of mobile phones. Have you ever paid attention to the harm it brings?
There is news that a mother took her two-year-old child out to play. When crossing the street, my mother stopped at the red light. When waiting for the green light, she took out her mobile phone, watched the news with relish and brushed WeChat ... My mother was completely immersed in the world of mobile phone network and forgot to look after the children. Two-year-old children ran to the street to play. Unfortunately, it happened ... the car didn't have time to brake, and a car accident brought a fresh life to an abrupt end. When everyone is blaming the driver, is the poor mother blaming herself? In recent years, there are countless traffic accidents caused by using mobile phones, which makes people forget the minimum rules and requirements and leads to tragedy.
I remember reading such a link, which was the cry of a seven-year-old child: Dad used to love me very much and always took me out to play on weekends. However, since the unexpected arrival of mobile phones, the focus of dad's life has changed. I pick up my mobile phone whenever I have time, but I can't put it down to browse the news ... everything at home seems to have nothing to do with him. Mobile phones have alienated our family. It's all the fault of the mobile phone!
Mobile phones make students' eyesight worse and worse, and the information they contact is mixed.
Mobile phones have two sides. It is like a knife, we should hold the handle and let it work for us; Instead of holding it on the blade and letting it cut our hands!

Nowadays, mobile phones, whether "Apple" or "Samsung", are becoming more and more advanced and have more and more functions. As a result, mobile phones have gradually become an indispensable thing in people's lives.
Watch out! Your mobile phone is your killer!
This is not an alarmist! Why is the mobile phone your killer? This killer will slowly "kill" you inadvertently, whether mentally or physically.
It is the killer of thought. Now the capacity of mobile phones is getting bigger and bigger. Even if you download games endlessly, the exquisite high-resolution screen attracts you to play games and makes you more addicted to the fun of games. Addiction came quietly. This addiction will erode your mind bit by bit. Until one day, you suddenly put down your mobile phone and found that you knew nothing but proficiency.
It is also a killer of family ties. An old man was at the dinner table of a family gathering, because his grandchildren and everyone were holding mobile phones, and no one paid attention to him. Suddenly, I dropped the plate angrily and left angrily. You should know something about this kind of thing, right? Do you have this situation? Of course, I don't know. If there is, at this time, the killer has locked you. Until one day, you suddenly put down your mobile phone and find that your relatives are disgusted with you or have left you, then you can never get it back.
It is the killer of life. Countless people cross the road with mobile phones, regardless of speeding cars, so they will pay the price and even die. Everyone should know that the law says "No talking on the phone while driving". It is forbidden to connect the phone, let alone take out the mobile phone to play. Have you ever pulled out your cell phone in the street? If this happened to you, the killer's gun was already aimed at you. Until one day, you suddenly looked up and suddenly found yourself in the middle of the road, and a heavy truck came to you. At this time, you immediately waved your mobile phone to attract the driver's attention. I didn't expect the driver to hold the mobile phone. Bang! ...
My friend, you can't let this killer lurking around you put down the "butcher knife", but you can choose to stay away from it and don't let your mobile phone target you. Friend, listen to me, it is really a killer!

I don't know when it started, restaurants, buses and subways. At first glance, everyone was hanging their heads and flipping their mobile phones up and down with their thumbs. The ranks of "low-headed people" have gradually grown.
It is better to say that the "low-headed family" cannot do without the mobile phone than the "low-headed family". A well-known university in China conducted a survey of students, and 80% of the students said that they felt anxious if they didn't seize the opportunity one day. It can be seen that people's dependence on mobile phones has created the group of "low-headed people".
Man, don't bow your head anyway.
If you keep your head down, even the basic emotions will gradually pass. A CCTV news report: "At a family dinner in Qingdao, the old man left angrily because his children always looked down at their mobile phones." This reflects the Spring Festival reality of many "low-headed" families. For the "low-headed people", the fun of the Spring Festival is to look at the photos you have taken and how many people like them. The joy of watching the bustling fireworks with children in the early morning, the feeling of listening to parents talking about the past at the dinner table, and the joy of visiting temple fairs with friends have long since disappeared from the "low-headed family", leaving only the expressionless face when brushing friends. Their emotions have long been robbed by mobile phones.
If you lower your head, the quality of life will be greatly reduced. I don't know if you have noticed that in recent years, the seats in the library have gradually become full on weekends; There are fewer and fewer people walking in the park at night; There are no crowds in the scenic spots in early spring. All this "benefits" from the growth of "low-headed people". The feelings of the "low-headed family" have long since disappeared. How can they study, read, enjoy the scenery and travel with great interest? Low-headed people are always active in Weibo's circle of friends, but they never "suddenly look back" at the end of the year, because their quality of life is so low that they have nothing to say for a year. Their lives are already full of mobile phones.
If you lower your head, humanity will gradually disappear. The feelings and life of the "low-headed family" have long been occupied by mobile phones. Every day they always look "indifferent" and there is no point in doing anything. In recent years, the news that "the old man fell down in the street and no one wanted to help" is everywhere. It is precisely because of the growth of "low-headed people" that their moral bottom line, sense of rules and humanity have long since vanished, leaving only a body dominated by mobile phones. So dare I ask, what's the point of living? Their humanity has long been strangled by mobile phones.
Put down your mobile phone, walk around with your parents, play more games with your friends, and look up to enjoy the attractive sunset glow. Don't look down anyway.
