Have you ever been online? In a few words, talk about the advantages and disadvantages of surfing the internet. Reply quickly!

Network is the product of the development of science and technology, and it is also the symbol of the information age. As middle school students, we should pursue and explore.

Although this is a virtual space, its advantages of convenience, quickness and flexibility expand our knowledge and give us a space to travel. Its appearance has changed people's traditional way of thinking and given us great help in life. Sitting at home, you can browse a lot of rich books in online libraries; You can receive a letter from Wan Li in a few seconds, and you can get all kinds of delicate information from all over the country in the shortest time. Learn more knowledge through the distance education network run by various schools and so on. It is precisely because of these advantages of the network that it is favored by more and more teenagers.

However, many people think that the disadvantages of surfing the Internet for middle school students outweigh the advantages. Indeed, the Internet is a complex thing, and its interior is full of all kinds of information, such as reaction, violence and pornography. There are too many such mixed things, and our middle school students have limited autonomy, so it is really difficult to resist the amazing attraction of the Internet.

But the network is a new thing, and the self-control of middle school students and the attraction of the network can't be compared at all. The attraction of the internet is endless, but the self-control of middle school students is limited. According to the incomplete statistics of UNESCO, the United States accounts for 20% of the total number of middle school students who surf the Internet for the main purpose of learning, Britain accounts for 15%, and China only accounts for 2%. This striking contrast properly shows that the self-control of middle school students is not as attractive as the Internet. It's like a newborn baby. After all, it needs careful support. Under the correct education and guidance, it will grow up, build the country and make contributions. But if so, it will inhibit students from surfing the Internet. Isn't it just killing the baby in the cradle? A lot of middle school students surf the internet, and some of them are adversely affected, which just shows that whether they are adversely affected depends on their own quality and will. As the saying goes, "people are not afraid of the oblique shadow." As long as we are willing to stay away from this kind of network communication that indulges people's thoughts, we will naturally not be affected by it.

The difference between advantages and disadvantages lies in how you use it and how to arrange your time reasonably. If it is used to play video games all day and night, it must be a disadvantage. If used for learning: the advantages outweigh the disadvantages. If used for chatting and games, the disadvantages outweigh the advantages.

Harm of surfing the internet

First, it poses a potential threat to the formation of young people's outlook on life, values and world outlook. Internet is an endless "net" with rich and complex contents. Teenagers frequently contact with the propaganda and cultural ideas of western countries on the Internet, which makes the traditional cultural ideas of China precipitated in their minds conflict with the mainstream ideology of our country, and makes teenagers' values tilt and even blindly follow the West. In the long run, it will exert a subtle influence on the outlook on life and ideology of young people in China, which is obviously a huge potential threat to the political stability of the country.

Second, the Internet has made many teenagers indulge in the virtual world of the network, divorced from reality, and also made some teenagers neglect their studies. Different from the real social life, teenagers face a virtual world online, which not only meets the needs of teenagers to possess all kinds of information as soon as possible, but also leaves a broad imagination space for interpersonal communication without having to 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 day rather than face the real life. However, unlimited internet access will have a great impact on daily study and life, and even seriously ignore learning.

Third, bad information and cyber crimes on the Internet pose harm and threat to the physical and mental health and safety of teenagers. At present, the harm of the Internet to teenagers mainly focuses on two points. First, some people commit crimes such as fraud or sexual assault; On the other hand, it is the harm 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, teenagers with weak self-control are often out of curiosity or impulse, and will further look for similar information, thus falling into it. The survey also shows that more than 90% of teenagers who have been exposed to online pornography have sexual crimes or motives.
