Advantages and disadvantages of surfing the Internet All technologies are double-edged swords, and the Internet is no exception. Inter originated from ARPA, the predecessor of the Advanced Research Projects Agency of the US Department of Defense. The network was put into use on 1969. At first, it was only used in the military. Later, through the improvement of Joseph, the father of the Internet, the Internet constantly entered our lives, making our lives rich and colorful. Internet makes information browsing faster and more convenient. If it's at 1990, we should look up all kinds of information about America, go to the library or make long-distance calls to ask our relatives and friends in America. It's different now. With the internet, you can find all kinds of information about "America" with a click of the mouse, and it doesn't take ten seconds. Internet makes the communication between people closer and faster. In ancient times, if you lived in Dongguan and wanted to write to your relatives and friends in Beijing, you had to send the letter by horse, and the time ranged from one month to one year. Modern can make long-distance calls, but it is very expensive, and you can't send documents or pictures; Now with Inter, we can communicate with friends and relatives in distant places and contact American customers through QQ and E-mail. It only takes about 1 yuan to talk for an hour, and you can also use videophone, so the distance between people is getting closer and closer. However, the Internet also has many shortcomings. It has become the best weapon for criminals. Criminals use the internet, a virtual and vast world, to carry out criminal activities. They wear the protective clothing of the internet, so that people can't see their ugly hearts. Newspapers often report that "a woman in XX was cheated to death because of QQ", which is an ironclad fact. In addition, there are many "hackers" who spread viruses everywhere, greatly reducing the speed of the Internet and seriously blocking the Internet highway. To make matters worse, some illegal websites actually provide pornographic, violent and other pictures and words on the Internet, which seriously poisons people's minds. In today's society, the Internet provides us with an infinitely vast land. Dear netizens who grew up in this land, don't let this land be abandoned, use it to cultivate rich fruits! Advantages and disadvantages of teenagers surfing the Internet The rapid development of knowledge economy has made the Internet a major theme in today's society. At present, the network is not only a symbol of fashion and trend, but also a concentrated expression of a country's overall scientific and technological level and even its comprehensive national strength. The computer Internet in China started late, but in recent years, its development momentum is also extremely rapid. According to the survey of China Internet Information Center, as of June 20001year, the number of netizens in China has exceeded 20 million, of which more than 85% are teenagers, and the absolute dominant position is unmarried male teenagers with high academic qualifications. What do so many teenagers watch online? How will the Internet affect their study, life and way of thinking? Is it good for teenagers to surf the Internet? Scholars from China Academy of Social Sciences conducted a survey on teenagers' Internet use in Beijing, Shanghai, Guangzhou, Chengdu and Changsha. The data shows that among teenagers, there are slightly more boys (56.6%), and the higher the grade, the higher the proportion of users. High school students account for 56% of high school students, junior high school students account for 36% of junior high school students, and primary school students account for 25.8% of primary school students. Among the overall users, junior high school students account for the highest proportion, accounting for 42%, followed by primary school students and high school students. The survey also shows that the higher the educational background of parents, the higher the proportion of their children users. The survey report also shows that nearly 80% of young users have used the Internet since 1999. The highest proportion of netizens is at home (58%), followed by Internet cafes (20.45%) and parents' or others' offices (15%). The average online time of adolescent users is 2 12 minutes per week. The portals that teenagers often use are Sina, Sohu, 163. COM Teenagers spend 60.3% of their online time on mainland Chinese websites, 25.2% on overseas Chinese websites and 14.5% on foreign websites. 8.4% parents have no restrictions on their children's surfing the Internet, and most parents control their children's surfing time. According to the survey, teenagers' online purposes are divided into practical purposes, entertainment purposes, using network technology and looking for information. More than 50% of the functions used are online games (62%) and chat rooms (54.5%), followed by e-mail (48.6%). About 50% of young users have friends who keep in touch by email; 25.2% young users often speak in chat rooms or BBS; 37.6% teenagers use ICQ to contact friends they know or don't know. Teenagers' needs for the Internet are mainly "getting news", "satisfying personal hobbies", "improving learning efficiency", "researching interesting issues" and "making new friends". From the above data, it can be concluded that the Internet has become a main window for teenagers to understand the outside world. So, what impact does the Internet have on teenagers? The influence of the Internet on teenagers is mainly manifested in the following aspects: First, the Internet provides teenagers with a broad campus for learning and learning. At present, taking classes in online virtual schools has become a novel educational model in foreign universities and middle schools. According to statistics, by July 2000, nearly 65,438+0,000 schools in China had registered domain names, and many of them had established complete school websites. Teenagers can not only know the situation of the school in time through the internet, but also learn the courses directly, communicate directly with the teachers of the school, answer questions and gain knowledge. Many networks (323131335323635438+0343130323136353585e5a5eb931333236393639) have been established one after another. Second, the Internet provides a new channel for teenagers to obtain all kinds of information. Getting information is the first purpose of teenagers surfing the Internet. At present, young people have a wide range of concerns, and traditional media can't meet the interests of so many young people in time. The huge information capacity of the Internet meets the needs of young people to the greatest extent and provides them with the richest information resources. Now, the Internet is becoming the best source for teenagers to get all kinds of information. Thirdly, the Internet helps teenagers to constantly improve their skills. Some experts and scholars in the United States regard computer skills as one of the five basic skills that successful young people must master in the future, because on the Internet, we can find almost all kinds of information related to all aspects of human life, which can be said to be an inexhaustible treasure house of knowledge for young people who can skillfully use computers. Fourth, the Internet helps to broaden the thinking and vision of teenagers, strengthen exchanges and communication among teenagers, improve their social participation and develop their inner potential. Because of the inclusiveness of the Internet, teenagers who surf the Internet are in a completely different environment from real life. In the process of thinking, teenagers not only exercise the ability of independent thinking, but also improve their ability to analyze and judge things. The interactivity of the network enables teenagers to make friends, participate in the discussion of social issues and express their opinions through online chat rooms or BBS. The endless network will also greatly stimulate teenagers' curiosity and thirst for knowledge, so that their potential and potential can be effectively developed. The above four points are the positive effects of the Internet on teenagers. So, does the Internet have any negative effects on teenagers? Internet is also a double-edged sword, which has both positive and negative effects on teenagers. As more and more teenagers gradually come into contact with and go deep into cyberspace, the negative impact is increasingly prominent. Mainly concentrated in the following aspects: First, the Internet 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. Compared with the positive impact of the Internet on teenagers, its negative impact is more prominent and acute. In order to solve these problems, give full play to the positive role of the Internet to teenagers, and abandon and curb the negative impact of the Internet on teenagers, we should do the following work: First, establish and improve relevant legal mechanisms as soon as possible, issue relevant laws and regulations, and take effective measures to prevent the use of the Internet to commit crimes or spread unhealthy information as much as possible. Second, intensify efforts to gradually realize the networking of existing youth organizations and rights protection institutions. Three, occupy the network position, establish a number of quality, hierarchical, distinctive, can attract young people's online patriotism education websites and bases. Fourth, strengthen the research work on the influence of Internet on teenagers, and make correct countermeasures. Five, vigorously cultivate young educators to adapt to the requirements of the network era. 6. Intensify publicity to make teenagers realize the negative impact of the Internet, so as to effectively reduce and avoid the harm of the Internet to teenagers and make them play a positive role to the maximum extent. Seven, often hold online activities conducive to the healthy growth of young people, to attract young people to actively participate in, to achieve a subtle role in education and guidance. Generally speaking, the Internet has both positive and negative effects on teenagers. Neither can be ignored. We can neither let it go because of its positive factors, nor choke it because of its negative factors.
