Internet has become a popular word now. In the past, people often used "Have you eaten?" Say hello, now many of them are changed to "Are you online?" This change reflects the progress of society, the development of science and the birth of a new era-the Internet era. The network has become a bridge between people, and the way to understand the outside world has become more and more important and irreplaceable.

Dialectical materialism thinks that things are like a double-edged sword, which has two sides, that is, it has its advantages and disadvantages, so how to treat the double-edged sword of the network?

In my opinion, surfing the Internet can broaden our horizons and broaden our access to knowledge. For example, we can listen to the lectures of famous teachers, consult rich materials, learn about major events at home and abroad, invite us to swim in the ocean of knowledge and extend our limited energy. Online learning can make us change from passive to active, give full play to our main role, study in online schools, and ask questions without scruple until we understand them. Sometimes some boring knowledge in textbooks becomes interesting on the internet, which greatly enhances the enthusiasm for learning; Secondly, netizens exchange ideas and discuss life, so as to solve their worries and enlighten their hearts. At the same time, we can overcome our face-to-face timidity and shyness, so that everyone is willing to participate and show themselves, thus improving their learning ability and communication ability. These are all advantages. On the other hand, there are still many deficiencies in the state's management of Internet cafes. Some shopkeepers forget "virtue" when they are greedy for money, tempting us to patronize illegal websites, leading them to indulge in virtual worlds. In addition, as a special group, our middle school students' physical and mental development is not perfect, which leads to our poor self-control, strong dependence and weak ability to distinguish right from wrong, so that sometimes we can't handle online problems correctly. For example, some people are too obsessed with online chatting and games, which leads to spiritual emptiness, distorted outlook on life, world outlook and values, and some even embark on the road of crime. These are all shortcomings.

I remember a sentence I said when discussing with my friends: "The Internet is a double-edged sword, beautiful but poisonous." Nowadays, the Internet has entered our life with an irresistible trend. For our middle school students, the key is to guide them correctly, treat the influence of the network in two ways, take its essence for their own use, and strive to be a useful person to society.
