You do not need to exchange or participate in extracurricular programs can also make friends and talk to people everywhere. It is social network facebook, instagram, twitter, Yahoo!..... and there are many other useful social networks. Because they're so modern, you're too infatuated. You can sit for hours texting with new acquaintances and forget about your friends. Called the virtual world, life in it is extremely beautiful and attractive. Everyone can build a beautiful house on it and have a lot of people call you. Many of you have abused social networks to post unhealthy images just for the sake of getting people's attention. Using uncivilized words to express themselves or otherwise calling them "keyboard heroes" has caused many conflicts. There are many people who see incorrect information and images, but have a wrong lifestyle and an unstable spirit. And there is a common phenomenon of love online. This is not wrong but whether you are mature and smart enough to know if this is true love or truth this is just a scam. Many of you are gullible and believe in the sweet words of a person you have never met when you know that the guy you love is just a fraud. There are actually a lot of dangers that you don't anticipate. You can sit for hours online, immersed in the virtual world, and away from the real world. Young people will feel strange when stepping out into the real world, unable to determine their direction. It has led to the feelings of children and parents becoming more and more fractured, and friends gradually drifting apart. And the important thing is that your studies will decrease, your achievements will go down or in other words, university admission is too far away. So everyone needs to have a healthy lifestyle without being too attracted to social networks. In other words, social media is like a double-edged sword. If you know the uses it is extremely helpful. But if you are too passionate it can be the knife that kills your soul.

I agree that Facebook, Instagram,.. is one of the best website to share everything. First, it help us relax, relieve the sad story,... Relax is we can play game, chatting with friends,.. Relieve the sad story is we can tell someone who can to share and sympathize with us. Second, it help us make friends with many people. Make friends with many people make us can confident about communication. Special with foreigners, we can communicate with their to revision communiction skill, grammar, vocabulary. That's good for us. However, we mustn't abuse theem too much. Not everything posted, shared. We have to consider what should or should not. Generall, facebook also has its good side, bad side of it. we shouldn't trust too much on technology
