In my opinion, internet have both advantage and disavantage sides. Firstly surfing the internet in freetime is relaxing and we can learn many study tips in there too. Secondly, we can contact with our friends very easily and the internet also become very important now beacause of covid-19. Student need the internet to study online. However, rely too much in the internet bring many problems too such as: It causes eyes problems, obesity, and addited. Next, it's dangerous if you trust the people in the internet, they could using you for their own benefit. In short, we can't blame all fault on the computer if we see many bad things from it. Teenagers should be carefull when using the internet and it's only be used for a limited times.
