Do primary school students have more advantages than disadvantages, or do more disadvantages than advantages? The advantage of primary school students surfing the Internet-1,they can learn a lot of things that textbooks can't; 2. They can learn from each other by making friends; 3. The world that the Internet lets children know far exceeds the life world that they can directly experience. The disadvantage of primary school students surfing the Internet-1,which may cause conflicts between parents and children; 2. Some unhealthy websites will seriously affect teenagers' physical and mental health, and easily lead students to go astray and neglect their studies; 3. Online games will affect the normal study of primary school students, fascinate them and eventually give up their studies; 4. Excessive Internet access can also lead to poor eyesight. Network is a double-edged sword. The advantages and disadvantages of surfing the Internet cannot be weighed on the balance, which is more important. I think it varies from person to person. Let me give a real example: I have such parents around me. Since the child started primary school, she quit her education and began to accompany her. Everything pays off. After graduating from the sixth grade, her son was finally admitted to one of the five key middle schools in the city, and she got her wish. Later, she returned to work. What she never expected was that the child had to drop out of school because of autism in just one year. However, the chief culprit of children's illness is online games. She is very disciplined and has no idea when her children are addicted to online games. At the beginning, the school teacher left homework in the QQ group, and the children had the opportunity to contact online games, so they were addicted to it. When she found that she was strictly disciplined, the children began to play truant and go to the internet cafe outside. Later, the above tragedy was brewed.
