What are the advantages and disadvantages of surfing the Internet? Point them all out.

Online education is also prone to excessive dependence on teenagers, who lack direct experience gained in practice. After surfing the internet, some people think that everything can be obtained from the internet, but it is not, because the normal process of teenagers' growth is irreplaceable. Different from the past education or media, online education is mainstream and controllable. It lacks authority, dominance and diversity, which will not only bring information to teenagers, but also affect their healthy physical and mental growth. In addition, due to the fast and convenient internet, teenagers are more detached from actual interpersonal communication and social activities, which is easy to make teenagers feel indifferent and cause a state of "self-isolation"; In addition, the network is a "virtual society" after all, and the contrast with the real society will affect the survival ability of teenagers in real life.

Network information is mixed and flooded, and junk information has an impact on students' comprehensive quality; Network communication has become an important factor to induce the conflict and anomie of students' outlook on life, world and values, such as virtual online dating, which makes students who don't understand the world deceived; By-products of network technology, such as "internet addiction and autism", make some students behave abnormally, appear psychological errors and even physical obstacles, causing physical and mental harm; The extensive use of network language enhances students' language expression ability and impacts their national cultural literacy.

The harm of online video games;

According to media reports, at least 10% of primary and middle school students are addicted to online video games. Experts pointed out that once teenagers indulge in online video games, they will have more and more strong psychological dependence and desire to operate repeatedly. When they can't operate, they will have symptoms such as emotional irritability and depression. Online video games are a form of entertainment for primary and middle school students, but indulging in online video games has many hazards: it damages eyesight and nerves, reduces the flexibility of the brain and affects academic performance; Induce violations of discipline, law and even crimes such as picking fights, extorting property, fighting, and participating in gambling.

Li Tianben is a cheerful student with good grades, but since he learned to play video games, he became fascinated in a few days. Take a small game machine to school and play on the computer at home. Black squares are dangling like jumping chess pieces, and they can't be driven away. Later, in order to play this game, he often played truant, lived in an Internet cafe, and borrowed money from his classmates to buy a card. One day, after playing the game, his online friends invited him to get money together and often surf the Internet. Li Tian agreed. A few days later, Li Tian and his friends were arrested by the police station.

Playing computer games takes time. If we play computer games too much, the time we spend studying will be greatly reduced, unless we are geniuses who can learn without watching. As far as we ordinary people are concerned, it is strange that our academic performance will not decline!

Secondly, playing computer games, especially for a long time, is very harmful to our eyesight and health. When you indulge in the pleasure brought by computer games, your eyesight will decline day by day unconsciously. When you finally wake up, it's too late! Maybe I can find the healthy body I once had. Playing computer games is especially a waste of money. As students, we mainly rely on our parents to give us pocket money. Imagine, whose parents are willing to give us money to play games online? Therefore, in order to play computer games online in Internet cafes, we are bound to ask our parents for it under various excuses, otherwise we will try our best to make money, and there is no mind to study at all, and some students even go to the point of no return. Why bother?

With the development of online games and the continuous updating of chat programs, people with poor control are addicted to the network. Some people spend hours playing games in internet cafes. What's more, in Internet cafes, they eat, drink, sleep and play games in groups, just like at home. Lack of concentration and high concentration can be described as extreme persistence. However, while enjoying the pleasure brought by the internet, people completely ignore that the devil of the internet is eroding people's health step by step. Some people take advantage of the ignorance of netizens and take some immoral measures to cheat on the convenient platform provided by the network. In China's criminal cases, the tragedies caused by cyber crimes account for a considerable proportion.

In this rapidly developing information age, we have to admit that the network has brought us a lot of convenience, but it has also added a lot of trouble.

1. The Internet has a potential threat to teenagers' forming a correct outlook on life, values and world outlook. The Internet is an endless "net" with rich and varied contents. Teenagers frequently come into contact with the propaganda rhetoric and cultural thoughts of western countries on the Internet, which makes their traditional culture and ideas in China conflict with the mainstream ideology in China, makes teenagers' outlook on life, values and world outlook tilt, and even blindly follow the West. In the long run, it will definitely exert a subtle influence on the ideology of young people in China and form the potential energy of social stability.

2. The Internet makes many teenagers indulge in the virtual world, divorced from reality, and also makes some teenagers neglect their studies. Different from the real society, teenagers face a virtual world online, which not only meets the needs of teenagers to possess all kinds of information, but also leaves a broad imagination space for interpersonal communication. Chatting, making friends and participating in online games with a constantly changing new image will make it easier to get success and be noticed by others, and you can express your opinions at will, without being bound by any laws and regulations, let alone bear the pressure and responsibility in real life. These characteristics of the virtual world make many teenagers prefer to indulge in the illusory environment all night rather than face the real life. However, unlimited access to the Internet has had a great impact on their daily study and life. Those who are light have poor eyesight, low spirits and poor academic performance, while those who are heavy neglect their studies.

3. Bad information and cyber crimes on the Internet are harmful to teenagers' physical and mental health and safety. At present, the harm of the Internet to teenagers mainly focuses on two points. One is that some people commit crimes such as fraud or sexual assault, and the other is the poison of yellow garbage to teenagers. According to the investigation of relevant experts, 47% of non-academic information on the Internet is related to pornography, and the Internet makes pornographic content easier to spread. According to incomplete statistics, although 60% of teenagers inadvertently come into contact with pornographic information on the internet, their self-control is weak, and teenagers often look for similar information out of curiosity or impulse and indulge in it.

Now online office is very fashionable, saving a lot of money and improving efficiency; The network provides businessmen with the latest business opportunities; Network becomes the new home of graduates; The network also makes people feel the richness of their spare time life in such a vast network. Most students, especially boys, are immersed in online games, and some even go far and don't meet for a week or even a month. Some students' parents are not far from Wan Li. When Wan Li came to school, he repeatedly said to the teachers and school leaders with tears: "The children don't listen to me, please save my children!" Did the teacher ignore it? Is the school not paying attention? Neither. Which teacher doesn't want his students to be outstanding? I've said everything I should, and I've tried everything I should, but to no avail, isn't the teacher chilling? How can those students who failed many courses and didn't get their diplomas explain to their parents that it was their parents who worked so hard to pay for our schooling? Who can understand the distressed parents?

The rapid development of the Internet has brought loopholes to unscrupulous businessmen. There are many bad websites such as pornography, violence and gambling. Secondly, the internet has brought many disputes between people. Because the government's policy on the Internet is not perfect, many questions about intellectual property rights are constantly emerging. The Internet has not only brought invisible harm to people's minds, but also caused great harm to the health of many netizens. On TV, we have seen such reports many times: a teenager suddenly became paralyzed and unable to move because he played games online for too long, and in severe cases he went into shock and coma. Due to the radiation of the computer to the human body, if people sit in front of the computer for a long time without activity, it is very easy to cause all kinds of unpredictable physical injuries. The most obvious is the damage to vision.

Paper media still plays a great role, because it consciously splicing and integrating all kinds of news, entertainment and advertising information, providing very clear and useful information. Although the speed of information storage and updating on the Internet has great advantages, it is precisely because of the advantages here that people need to spend extra money on selecting and screening in order to find what they need, which leads to a lot of extra time and energy. Not only that, people often wander around on some rubbish and useless information, and can't get enough benefits. In my opinion, the biggest use of the Internet is communication, search and entertainment. When you complain about spending too much time online, you should be on your guard. The internet is usually just a superficial taste, and you can't expect to realize your powerful dreams, including a lot of reading and persistent learning. Time is never in a hurry, please turn off your mobile phone at the right time.

The benefits of the network

Mankind will enter the information age, and the network will be more and more strongly involved in our lives, getting closer and closer to our primary school students. Is surfing the Internet beneficial or harmful for primary school students? We firmly believe that the advantages of primary school students surfing the Internet outweigh the disadvantages. I will elaborate our views from four aspects: 1. Necessity. This is an era of knowledge economy, information is expanding and exploding at an unprecedented speed, and the future world is the world of network. If China wants to keep pace with the times in this information world, as the main force in the 2 1 century, it must be able to adapt to this high-tech society more quickly, have the ability to obtain effective scientific information from the outside world quickly and timely, and have the ability to disseminate scientific information, which is scientific quality. And the network has just adapted to this requirement. Didn't Comrade Deng Xiaoping say, "Computers should start with dolls"? 2. practicality. The resources of the online world are enjoyed, just like a cornucopia, an inexhaustible "golden mountain of wealth". Whoever works hard on this golden mountain will gain something. We can find learning materials from them at the fastest speed, learn more extracurricular knowledge, use the knowledge in class flexibly, promote the development of thinking and cultivate the creativity of primary school students. Surfing the internet can also transcend the time and space and economic restrictions and receive online education from prestigious schools. If you have any questions, you can always ask the teacher for guidance by email. Moreover, interactive learning, rich three-dimensional graphic display, language explanation and other multimedia content on the network make learning easy and interesting, which is beyond the reach of any textbook. 3. Reality. Dawning Project in our province is to rapidly promote education informatization, set up Internet classrooms in every primary and secondary school in our province, popularize computer Internet knowledge, promote primary school students' home access to the Internet, and realize distance education and knowledge sharing. Provide free online counseling for primary and secondary school students in the province, cultivate their interest and awareness in learning and applying information technology, and cultivate their ability to obtain, analyze and process information. Look around us again. The school website is booming. Do Secretary Lin Shouhua and Teacher Chen Xin also suggest that you visit the school website? Isn't the website of that year and the class in full swing?

Advantages: First, it can broaden your horizons. Surfing the Internet can keep abreast of current events and obtain all kinds of latest knowledge and information, which has a good guiding role in future study and life. Surfing the internet can enrich your mind. As long as you pay attention, you can learn a lot of knowledge that you can't learn at school. Second, we can communicate with foreign countries. One of the shortcomings that students often mention is lack of self-confidence and fear of dialogue and communication with the outside world. Now with the Internet, they can completely overcome this psychological barrier and broaden their horizons in the process of foreign exchange. The network provides a convenient channel for the exchange of educational resources. Not only teachers, but also students can log on to various educational websites through the Internet to obtain learning information. Third, it can promote the individualized development of teenagers. To eliminate psychological barriers, you can talk to netizens without scruple and reduce the psychological pressure caused by the burden of schoolwork.
