In modern societies, we can't lack internet because we need it to do everything more easily in all fields and on all aspects.

Thanks to internet, we can get an unlimited source of information that we can search very fast and easily whenever we need. We can learn or study a lot of subjects online and also take up many courses on internet without going to university, school or club. We can find a job or buy anything on internet. Therefore, it helps us save time, money and energy. It's also good for entertainment and relaxation. We can play games, listen to music, watch films, and update news every day. It's so useful for communication because we can chat, make friends or, send messages, emails, documents... to anyone all over the world. It's so convenient.

But, everything has both sides, and the internet is too. We can become addicted to the internet. We'll spend all the time on internet, especially on games online or bad websites. Nowadays, the youth are addicted to game online. There were a lot of murders who commit crime just for money to play game. They kill victims like violent actions in the games. Recently, I read a piece of news about a 14-year-old boy who killed his granddad savagely because his granddad discovered he stole his parents' money. Many young girls want to make friends or to find boyfriend. Then they met some bad guys who may trick, rape or illegally traffic them to foreign countries.

Internet addiction makes us get exhausted and lose our control; sometimes it can kill us on the keyboard. There will be many problems with internet if we do not know how to use it reasonably. So we should use the internet most effectively.
