Internet
Advantages and desadvantages:
In my opinion the internet is good when you know use it in a correct form and you aren't all the time in the computer using internet.
In spite of the fact that in internet you can study very well and very fast because you have a lot of seekers and places of information to consult all the themes.
Is very easy than when you are using internet, you disctract with a comercial or with something than you see and are interesting.
Other polemic theme are the social networks.
Are good because you can speak with your friends, meet new people... However are very addictive and have the danger than you can have virtual friends than in the real life aren't are a good persons.
