As you know that in this modern era, the internet, as the mainstream of media, plays a fundamental role in information transformation. They present a vivid and colorful world in front of us. Especially in light of Covid-19 pandemic, the internet is becoming more essential than ever. Nevertheless, the internet contains some unwanted elements or disadvantages as well. The following are the advantages and disadvantages of the internet. Admittedly, internet brings about lots of conveniences to us. It can transform information instantly. Moreover, the internet can let a person communicate with people in virtually any part of the world through the world wide web, social media or e-mail, without having to leave his room. With the help of such services, it has become very easy to establish a kind of global friendship where you can share your thoughts and explore other cultures. Internet also plays an important educational role. For instance, as I said, nowadays, on account of Covid-19, people are getting used to working at home or studying online. We can study history, culture, language from some educational programs on the Internet. Last but not least, people can get entertainment from internet, which is abundant in fascinating games and videos. Alternatively, for all its advantages and positive aspects, the internet has its dark and negative side as well. Firstly, many students spend too much time playing games and they are likely to neglect their studies. Thus, they couldn't concentrate in class. Besides useful videos on the internet, there are also lots of violent videos which are not suitable for children at all. They happen to click on a link or watch a video and try to imitate it. Furthermore, sitting continuously in front of a computer screen can seriously damage our eyes, and put a strain on our neck and shoulders. Children are in their developing years and these factors can create life-long problems for them. In conclusion, notwithstanding the disadvantages mentioned, I do reckon that internet is a good thing and a part of our lives. We must take advantage of it effectively.
