Surfing the internet has provided us with great help. After intense study, surfing the Internet can relax us. Surfing the Internet can make us feel happy and let us communicate with our distant relatives as close as possible. We can also use the network as a "post office" to send and receive emails through the network. This not only saves paper, but also is very fast! Now, we should not only remember the book knowledge, but also need a lot of extra-curricular knowledge. Where can we find this extra-curricular knowledge? Then you should seek the help of the computer. You can look up these materials through the internet. Surfing the internet is very fast, and it can be found in a few minutes, which saves a lot of time than looking up books, so it can save a lot of time, improve learning efficiency and be conducive to academic performance. What news can be known for the first time through the internet, so that we can know what's going on in the world without leaving home. "A scholar doesn't go out and knows what's going on in the world." Why not? But students, do you know? Network is neutral, it is a double-edged sword, which can not only benefit mankind, but also harm society. Especially since 1995, the network has played an increasingly important role, and its advantages and disadvantages cannot be ignored. The Internet has made many students addicted to the virtual world of the network and divorced from reality. Different from real social life, students face the virtual world on the Internet. Internet not only meets the needs of students 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 them prefer to indulge in the illusory environment all day rather than face the real life. They like to play online, even playing all night, which leads to the decline of physical fitness, inattention and listlessness. Unwilling to study, delaying their studies, brings infinite grief to parents. Besides online games, there are other unhealthy information that corrodes the hearts of young students. There is still a long time to surf the internet, which will reduce our eyesight. Everything in the world is complementary, with good and bad, and relative advantages and disadvantages. See how we treat and handle it, the advantages outweigh the disadvantages. On the contrary, the disadvantages outweigh the advantages. The network is mixed, good and bad. We can only observe, study, absorb and use the essence that is beneficial to us, eliminate the dross that is unfavorable to us, and correctly use the resources of the network to enrich our brains.
