Who said the host's opening remarks about the advantages and disadvantages of the network?

Speaking of the Internet, I think everyone will be familiar with it. I believe some students will say, "Internet is the center of life in the new century and an indispensable part of our study and life". Undeniably, the network has played an important role in our life and the development of IT economy, and the negative reports that followed are also increasing day by day. Take the sudden death of a senior high school student playing games in Nanchang on April 17 as an example. It is shocking that minors are addicted to internet cafes and do not go home, and they are keen on online games and even addicted to them. On June 16, an Internet cafe in Beijing caught fire. When people are still immersed in the tranquility of the city, 25 young lives are leaving us. This makes us hate Internet cafes, and indirectly becomes the killers of these young lives, forming a "spiritual dream ocean" that has a great influence on minors.

Among us, many students have fallen behind in their homework and studies because of surfing the Internet. There are also some people who are addicted to online games and spend all day playing games in Internet cafes. When we deeply experience the new feeling of online communication brought by QQ, we can't escape its "light and shadow". As young people, we are trapped in a virtual world and think it is a new continent worth exploring. It is precisely because of the existence of some website cultural rubbish that it is easy to bring some side effects to our surfing the Internet. Coupled with the lack of social cognition and self-protection awareness, it is impossible to get rid of the negative influence of the network to some extent.

At the same time, we can't deny the network because of its negative influence. The fishbone only gets stuck in the throat occasionally, but as long as we eat fish, we will certainly get nutrition. I remember a report not long ago: A girl with high paralysis finally found her own sky on the Internet with strong perseverance and persistence in the Internet. Of course, as middle school students, we have many opportunities to surf the Internet. Internet shows us various structures and becomes an important platform for our teenagers to learn knowledge, obtain information, develop their potential and entertain.

Indeed, as a new thing, the network has some shortcomings. But for such a new thing, we can neither regard it as a scourge nor stifle it because it will bring some negative effects; You can't blindly publicize its advantages. As students, we should naturally realize the disadvantages of indulging in online entertainment, pay more attention to the truly valuable information on the network, and contact the society through the network to improve our discriminating ability and thinking ability. At the same time, I believe that under the correct guidance of teachers, we can apply the tools of this era with a correct attitude.

2 1 century is the era of computer network, and today's students will bear the responsibility of future social pillars. Understanding and mastering computer network knowledge is the most powerful weapon to break through the future information age. Let us believe that by making good use of the tools of this era, we will eventually gather sand into towers and stand on the shoulders of giants.
