Speech on the harm of mobile phones 1 Dear teachers and students,
Good Morning, everyone!
Before I make a formal speech, I want to ask two questions: Do you have a mobile phone here? Raise your hands, please. Do you have anything with you? Yes, very few: it seems that there are still a few abnormal ones, just kidding; No: It seems that everyone is my child care. This result is in line with my guess, which shows the importance of mobile phones to us.
As we all know, the development history of mobile phones is very short, from a brick-like mobile phone to a palm-thick smart phone. It has only been used for more than 30 years, and its powerful functions are simply staggering. What telephone messages, QQ WeChat, novel TV, dictionary games, clocks and calendars, etc. , really, really feel a bit overwhelming. Yes, there is no denying that we can't live without mobile phones. She is our good friend and wife. Exaggerated, it has even become a part of our body. According to the survey, most people must take three things with them when they go out today. Want to guess, keys, wallets, cell phones? And in the survey, in fact, many people would rather lose their wallets than their mobile phones. Of course, this is relative. I don't know if you have watched the news. A university in Wenzhou launched a "24-hour farewell to mobile phones" campaign, in which 30 students participated, but 29 students kept themselves in the confined room for less than three hours. This result is really unbelievable. If it were me ... I think I'm no different from them.
In fact, mobile phones have caused us a lot of harm, such as radiation, bacteria, bad information and so on. But they always have more advantages than disadvantages, so we can't stop, but we have to understand that the mobile phone is just a tool, not really a piece of meat on your body, so there is no need to leave it all the time, but to put it down.
Of course, when I say put it down, I don't mean to say goodbye to it forever, because you can't do it at all, can you? I can't do it anyway. I just hope you can put it down and say goodbye to it at some point. For example, now, should everyone put down their mobile phones and listen carefully, even if what I said is really bullshit? We should continue to listen carefully, but only in this way can we show our respect for others and our high quality. For example, going to the toilet, in the survey, many people have the habit of taking their mobile phones to the toilet, which can only turn going to the toilet in ten minutes into a marathon fighting against the toilet, which is not only bad for health, but also affects other people in public places. The key point is that many people used to send their mobile phones into the Pacific Ocean together with feces when they went to the toilet, and the cost was higher. For example, when eating, whether you are with classmates, friends or family, you should put down your mobile phone and not attend to one thing and lose sight of another. This is the real treasure now. I think we can follow the example of the west and set up our mobile phones when we have dinner with friends in the future. Who touches them first will pay the bill? Besides, when we were in bed, we were tired of cell phones for so long during the day. Let's throw them away at night. Distance produces beauty. If you can hold a book and sleep with it, what a wonderful thing it is.
We need a mobile phone, but at some point we should put it down so that it can have a rest and calm down!
Thank you!
Speech on the Harm of Mobile Phones 2 Dear teachers and students:
Good Morning, everyone! I'm Lu from Class 1, Senior 1 (Science 1).
The topic of my speech today is "the harm of mobile phones to middle school students".
In recent years, mobile phones seem to have become a necessity of life. At that time, people were increasingly inseparable from mobile phones, which brought people closer and brought great convenience to life. While bringing convenience, it also brings various hazards, especially to our middle school students. The specific hazards are as follows:
1, affecting health.
According to statistics, the global mobile phone users have tripled, and the harm of mobile phones will be greater than the corresponding harm. Frequent contact with mobile phones affects body parts, such as eye cataracts, mobile phone dermatitis, and memory loss. Long-term use of mobile phones can easily lead to mobile phone dependence and even auditory hallucinations.
2. Affect mental health.
Mobile phone short message is a scientific and technological innovation in the field of communication, which provides a fast and simple modern means for people to exchange information and convey emotions. However, some people indulge themselves with it. Some young students are exposed to some bad information through mobile phones, which forms a psychologically unhealthy reading pleasure. Too many text messages can make people insane. If direct communication is replaced by mobile phone communication, they will not accept the differences between people and do not know how to respect others, which will seriously affect the normal communication between classmates. Middle school students who are in the "seemingly incomprehensible" stage are easily attracted by unhealthy content and go astray. In addition, teenagers' use of mobile phones is also prone to compare with others, which affects their mental health.
3. It is easy to interfere with rest and reduce learning efficiency.
A considerable number of students use mobile phones not to strengthen contact with their parents and report their academic achievements, but to make friends. For 24 hours, the students kept sending messages and chatting endlessly. After their academic performance plummeted, they seldom called their parents except asking for money in another way. Whenever the lights are turned off after going to bed, some students use their mobile phones to chat or fall in love with so-called bosom friends through charming night and faint moonlight. Some dormitories even use mobile phones to surf the Internet until the early hours of the morning, so that students in the dormitory can't sleep. Some students who want to study hate this and are miserable.
4, easy to breed trouble, accidents can not be prevented.
In the eyes of many students, mobile phones simply represent status and status, which seems to make boys more chic, affectionate and girls more attractive. Because the mobile phone is a valuable thing and a favorite of students, it will take a lot of energy and time to keep it, but it is still easy to be stolen. The phenomenon of losing mobile phones on campus happens from time to time, causing a lot of losses and troubles.
Besides, the students are young and can't stand the slightest injustice. Once there is a small contradiction, they will quickly call social youth to fight through their mobile phones. At the same time, frequent charging in the classroom may lead to electric shock accidents and school wiring failures. Some students have to scrimp and save in order to pay the telephone bill, or ask their parents for money on the grounds that the school has to pay the information fee, or even go out to do illegal things. There will also be a small number of students who are trafficked because of extensive communication with mobile phones outside the school.
In short, for middle school students, mobile phones do more harm than good, so stay away from them. As middle school students, we should be strict with ourselves. Don't let the mobile phone affect our study, and cultivate good behavior and study habits from the first day of junior high school. Otherwise, in the third year of high school, you can only say to yourself, "Young people who don't work hard are pathetic." Here, I want to say a word to my classmates, "Don't do it with small evils, don't do it with small goodness."
My speech is over, thank you.
The Harm of Mobile Phones Speech 3 Dear teachers and students:
Good Morning, everyone! The topic of my speech today is "The Harm of Mobile Phone".
Nowadays, mobile phones seem to be a daily necessity, which brings people closer and brings great convenience to people's lives. Mobile phone is also a double-edged sword, which brings us convenience and all kinds of harm, especially for our middle school students.
1, affecting health. According to statistics, the global mobile phone users have tripled, and the harm of mobile phones will be greater than the corresponding harm. Frequent contact with the body parts of mobile phones has the greatest impact, such as cataracts in the eyes, dermatitis on the skin of mobile phones, dependence on mobile phones caused by long-term use of mobile phones, and serious auditory hallucinations.
2. Affect mental health. SMS is a scientific and technological innovation in the field of communication, which provides a quick and simple modern means for people to exchange information and convey their emotions. 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. Because of 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. Middle school students who are in the stage of "seemingly understanding" are easily attracted by unhealthy content and go astray. In addition, teenagers' use of mobile phones is also prone to compare with others, which affects their mental health.
3, affect the formation of good moral character. In recent years, it is nothing new for students to cheat with their mobile phones in various exams. In the college entrance examination in Qianjiang and Shishou, Hubei Province in 20__, cheating on mobile phones occurred from time to time. With the popularization of mobile phones and the enhancement of their functions, there are more and more phenomena of cheating by using mobile phones. And more and more clever, such as tying headphones in sleeves, and some simply wear headphones on their ears and cover them with long hair. Whether cheating or sending false information is a sign of dishonesty, if it is not stopped in time and guided correctly, it will bring serious harm to the formation of students' good quality.
4, causing security problems. Because there are many mobile phone brands and the quality is mixed, it is difficult for consumers to tell them apart. Coupled with improper use in thunderstorm days, playing video games for a long time, the explosion of mobile phones sometimes hurts people. In some places, criminals take advantage of students' weak awareness of prevention and resistance to steal students' mobile phones. In July, 20 _ _ _, a california gurls, aged 16, suddenly exploded in his clothes pocket, causing serious consequences of second-degree burns.
In short, for teenagers, mobile phones do more harm than good, so stay away. In the new semester, we should be more strict with ourselves. All subjects should make use of the overall construction, learn to systematically sum up knowledge in the knowledge tree, so as to draw inferences from others, and also start from various small things to cultivate good behavior and study habits. "Don't use small evils, don't use small goodness".
My speech is over, thank you!
Harm of mobile phone speech 4 Dear teachers and students:
Good Morning, everyone!
Technology is a double-edged sword, and mobile phones as the main products of technology are no exception. If used rationally, it will undoubtedly benefit mankind, otherwise, it will not. Words like this have long been known, but how many people will carefully consider the objective value of this sentence when using mobile phones?
Everyone uses mobile phones, and moderate use should be encouraged when necessary. So if you play a game, it's not a bad thing.
So what are the hazards of improper use of mobile phones? In fact, you and I both know it, but today I will review it for you, hoping that you can learn something new by reviewing the past! First of all, I want to start with socialization, because apart from the traditional simple information acquisition, most people can't use their mobile phones without socialization, and it is true. Socialization is the communication between people in society. In today's mature information technology, virtual socialization and game socialization have undoubtedly become the mainstream forms of social interaction, and we will all enter the society in the future. If you don't master these two skills, it is undoubtedly inefficient to use traditional social methods. This is why we use mobile phones, but don't let it be an excuse for our addiction. Knowing and getting the results, overusing mobile phones is the crux of wasting time. Time waste is not only a waste of time using mobile phones, but also a waste of time caused by usual delays and distractions. Most of the time, these hours will be filled with quiet and peaceful night time. In addition, it may also lead to mood swings, myopia, glaucoma, skin inflammation, osteoporosis and other symptoms, and even lead to infertility and cancer! I don't think I need to elaborate on its other harm to human body. What's more, they spend a lot of money on mobile phones and games. Although the current network environment has improved compared with previous years, the existence of fraudulent information and pornographic gambling on drugs can not be underestimated. Modern information technology also has its own defects, and human beings are gradually aware of this and constantly criticize, reflect and correct it. I don't know if you still remember virtual reality, a topic of college entrance examination composition. In the virtual world, we don't have enough ability to distinguish right from wrong, and even let us lose the instinct of seeking advantages and avoiding disadvantages. This is the most important point. Don't let yourself get lost in truth and falsehood, falsehood and truth, narrow the furthest distance in the world and regain the small happiness in front of you. We humans invented virtual worlds and electronic products. If we want them to be manipulated by humans and benefit mankind, don't let them manipulate you!
If I were a driver, I wouldn't have an accident while driving. I would blame the traffic police. No driver will roll over because of the warning of the traffic police. If you don't pay attention to the traffic police's reminder, you will really roll over! It is up to everyone to judge whether the two "rollovers" are lighter or heavier! Why use a mobile phone? What should we do next? It is also left to everyone to think about.
This is the end of my speech. Thank you for your patience and wish you a "bon voyage".
Harm of mobile phone speech 5 Dear teachers and students:
Good Morning, everyone!
In 20xx, the first lawsuit of brain tumor caused by mobile phone appeared in the United States. Some people even suggested that "you should stop using your mobile phone before reaching a final conclusion". This case has also aroused widespread concern in society about cell phone carcinogenesis. Although mobile phones facilitate the contact between parents and students, they seriously affect the management of schools and students' learning.
First, it affects health and memory loss.
Studies have proved that teenagers' ears and skulls are tender, and cell phone radiation will cause irreversible damage to teenagers' brain nerves.
Harm, students equipped with mobile phones will obviously reduce their understanding, responsiveness and memory. At the same time, mobile phones can also lead to hearing loss, sleep quality decline and immune dysfunction. In addition, it is a carcinogen, which can induce leukemia and tumor.
Second, before Internet cafes enter classrooms and poison teenagers, students need to climb over the school walls to surf the Internet in Internet cafes.
Now, with the opening of the powerful function of GPRS, students can chat directly with QQ, browse the web, read materials and dial bad voice stations in the classroom at any time. If you download in the air by mobile phone, 20 yuan can download about 500 pages of books and 50 novels; If you chat with QQ, the standard of 10 yuan can cover 70M traffic. To put it simply, you can't work from morning till night. As a result, students have to work overtime when reading novels and chatting. Where did they get the energy and time to take care of the boring knowledge in the textbook? No wonder American primary and secondary schools prohibit students from wearing mobile phones.
Third, interfere with others' rest and reduce learning efficiency.
A considerable number of students use mobile phones not to strengthen contact with their parents and report their academic achievements, but to make friends. For 24 hours, boys and girls kept texting and chatting. After their academic performance plummeted, they seldom called their parents except asking for money in another way. Whenever the lights are turned off after going to bed, some students use their mobile phones to chat with so-called intimate friends or send disgusting short messages on QQ, and some dormitories even use their mobile phones to surf the Internet until the early hours of the morning, so that the students in the dormitory can't sleep. Some students who want to study hate this and are miserable.
Fourth, interfere with teaching order and despise teachers' labor.
Our students' self-control ability is not strong, so it is difficult to resist the temptation of mobile phones. Some students often use their mobile phones to play games, send short messages, listen to music and read novels in class, which greatly reduces the teaching effect of teachers and makes them ignorant of the lecture content. Some classes have mobile phones ringing in almost every class, which seriously disturbs the class order and is a contempt and rudeness for the hard work of teachers. In addition, some students dare not play with their mobile phones in class, but they really concentrate all their spare time on their mobile phones. Apart from eating, they can hardly do without their mobile phones.
Five, seriously corrupt the style of examination, completely blow across the style of study.
After students have mobile phones, they are easily influenced by all kinds of bad information in society. Ideas such as reading is useless, eating, drinking, keeping up with the joneses, vanity, brave fists, puppy love and so on will all affect our students. Some students spend most of their time and energy playing with mobile phones, and they are at a loss when it comes to exams. Except for the college entrance examination, all exams, big and small, are basically cheated by mobile phones. Cheating on mobile phones is becoming more and more serious. Our usual monthly exams, mid-term exams, final exams and academic level tests are useless in the eyes of some students, and the authenticity of the level is also very doubtful. This will inevitably lead to a large-scale and substantial decline in our quality education.
Six, trouble is easy to breed, and accidents are hard to prevent.
In the eyes of many students, mobile phones simply represent status and status, which seems to make boys more chic, affectionate and girls more attractive. Because the mobile phone is a valuable thing and a favorite of students, it will take a lot of energy and time to keep it, but it is still easy to be stolen. The phenomenon of losing mobile phones on campus happens from time to time, causing a lot of losses and troubles. Besides, the students are young and can't stand the slightest injustice. Once there is a small contradiction, they will quickly call social youth to fight through their mobile phones. At the same time, frequent charging in the classroom may lead to electric shock accidents and school wiring failures. Some students have to scrimp and save in order to pay the telephone bill, or ask their parents for money on the grounds that the school has to pay the information fee, or even go out to do illegal things. There will also be a small number of students who are trafficked because of extensive communication with mobile phones outside the school.
In view of the serious harm of middle school students' using mobile phones, some famous middle schools in Jiangxi Province, such as Linchuan Middle School, Jiangxi Normal University Affiliated Middle School, Ganzhou No.1 Middle School and Ganzhou No.3 Middle School, have taken the lead in promulgating a ban on using mobile phones-prohibiting students from wearing mobile phones at school! Xunwu No.1 Middle School also clearly stipulates that all students who find that they use mobile phones at school will be confiscated. Today, this practice in our school has won wide support from parents, and even lawyers in our county say it is quite necessary. Some government officials and educational experts are going to suggest to the National People's Congress that primary and secondary school students should be prohibited from using mobile phones by law. The functions of mobile phone such as video, chatting, surfing the Internet, downloading, texting and playing games have gone far beyond the use of middle school students. It should be an entertainment tool for adults. For those middle school students who have poor ability to distinguish right from wrong, weak self-control, strong curiosity and strong playfulness, they are in the critical period of learning knowledge, delaying their studies and ruining their future. This runs counter to the original intention of parents to wear mobile phones for their children. At the same time, mobile phones are so hidden that we can't know what students do with them. If you want to keep the quality of middle school education from declining and let students learn something at school, it is the general trend to ban mobile phones. Prohibiting middle school students from wearing mobile phones is responsible for students and parents, and it is also the most fundamental and effective way to prevent students from playing with things.
Harm of mobile phone speech 6 Dear teachers and students:
Good Morning, everyone!
Before we begin, I want to ask you a few questions. Are you always afraid that your mobile phone will run out of power? Do you often have the illusion that your mobile phone will ring? Do you have to brush the space and Weibo every once in a while? If so, I solemnly declare: dear, you have a disease called "mobile phone control" In today's era of rapid development of science and technology, the powerful functions of mobile phones have brought great convenience to our lives. We control the mobile phone and are also controlled by the mobile phone. If you don't believe me, you may wish to recall that it is always safe to go out without a mobile phone. If there is no signal on your mobile phone, are you anxious like an ant on hot bricks? Would you feel at ease if you didn't check your mobile phone once in a while? Bowing your head is the most common representative action of "low-headed people" No matter on the road, on the bus, in the canteen, in the classroom, you can see the back of playing with your head down. It is a common phenomenon to bow their heads and play, and few people realize the harm of indulging in square inches. Not to mention the direct harm of mobile phone radiation to human body, it is said that mobile phones let people communicate through screens and networks, and people can't see their true expressions. On the contrary, they are words. People put too much emotion into the virtual world and are somewhat alienated from reality. People around you seem to become transparent. Dependence on mobile phones makes us neglect communication with relatives, friends and colleagues. The noise in the mobile phone is in stark contrast to the silence of all beings outside the mobile phone. Maybe everyone has left others or been left behind by others because of playing mobile phones. As the saying goes, the furthest distance in the world is not between life and death, but when I stand in front of you, you are playing with your mobile phone. Mobile phone control not only gives criminals the opportunity to commit crimes, but also brings harm to their own lives.
Looking down at the phone for a long time is equivalent to hanging 20 watermelons around your neck! God, how can our necks stand this? In addition, mobile phone radiation is also a big threat. According to research, cell phone radiation can cause headaches and insomnia, and even lead to Alzheimer's disease! In addition, when answering the mobile phone, radiation will damage the lens of your eyeball and induce cataracts. Radiation can also damage your ears. Studies have shown that even talking for nearly an hour every day can lead to permanent hearing loss; Increase the hidden danger of brain tumors! After reading the information, I was shocked: the original mobile phone has such great harm!
Not long ago, an old lady of 17 years old in Hubei Province accidentally stepped on her mobile phone and fell into the pit of 15 and 16 meters, and died unfortunately. It's really sad that a small mobile phone took a fresh life like a demon. According to statistics, mobile phone control averages every 6. Check your mobile phone every 5 minutes. If people are awake for 16 hours every day, then these people will probably check their mobile phones 150 times a day. How much time do you have to visit your relatives, friends and teachers? In this materialistic world, there are more and more temptations of material, and we ordinary people will inevitably be obsessed with material. However, there is a limit to everything. When you hold the phone tightly, please don't forget to hold the hand of the person you love and the person you love. When you lower your head to care about your mobile phone, please don't forget to look up at this beautiful world, because there are many beautiful things in this world that deserve your care and experience. The mobile phone can be played, but don't be controlled by it. Only when you feel the real world can you have real fun. This is the real life.
Thank you!
Harm of mobile phone speech 7 Benefits of mobile phones Since scientists invented mobile phones, they have reduced a lot of troubles for many people. For example, I wanted to return something to someone else, but I don't know if that person is at home. But since I have a mobile phone, I can call that person and ask if you are at home, and I will give it back to you. Look, how convenient it is to have a mobile phone. You can also send messages of blessing at home, instead of visiting friends' homes all the way.
I remember once, I went back to my grandmother's house. My grandmother asked me to invite my uncle to dinner. But now, since I have a mobile phone, grandma has cooked and asked my uncle to eat. I don't have to go to my uncle's house and ask him. One phone call is enough, and the phone bill is cheap and affordable. I mind texting, I can store a lot of calls and I can adjust the volume at any time. You see, since this mobile phone came into being, people in rural areas used to call home for dinner. Call now. This has changed so much!
The advantages of mobile phone are very necessary and important in modern society, because it brings a lot of convenience to our life and also provides us with a new way to contact with the world.
First, mobile phones bring people closer, because people can keep in touch at any time. Especially for those who are far away, mobile phones are definitely the best tool to maintain and strengthen relationships.
Second, mobile phones make our work or study more efficient. People can use mobile phones to search data, transfer files and so on. For students, they don't need to carry books, so they can read on their mobile phones at any time. In addition, the mobile phone makes our life more exciting, because it has more and more functions, such as watching movies, listening to music, writing blogs and so on. Finally, we can use mobile phones to understand what is happening around the world. With the help of the telephone, we can get the latest news even if we stay indoors. In a word, mobile phones provide great convenience to our lives, make our lives better and make it easier for us to contact with the world.
The benefits of mobile phones have many benefits for us in life. On weekdays, our family can chat with relatives and friends in our hometown through mobile phones. Enter the sweet words you want to say to the person you love into a rectangular box, and then click send, and the next second we miss ta or ta will receive it. Imagine that when we are in a foreign land and suddenly receive a short message from the other side of the earth at a certain second, Ding Zhu will see that it is actually a sweet greeting from a family on the other side of the ocean. How exciting, how I wish I had super powers, set the time at that moment and enjoy it slowly!
Mobile phones have many benefits for us, but we should not rely too much on them. Be careful of the damage of mobile phones to our eyesight!
