Now many of my classmates like to surf the Internet in their free time.I think Internet can bring us both advantages and disadvantages.For example，I can surf the internet to learn more information about the world. And I can make more friends on it. I can also talk with my teacher or my classmates some problem afterclass。
However, Internet can make some problems at the same time. If you spend too much time on it ,you will becaome lazy and can't put your heart on study. It will be even worse if you feel you can't live without Internet.So we must be careful when we use the Internet.

Much of modern communication is done through the Internet as it transmits all kinds of information. Teenagers compose a major group of the Internet users, as we use it to research for papers, chat with friends and read e-mails.Obviously, we use the Internet because we need it. We need the quick access to information and knowledge. We need to communicate with our friends via QQ or Skype. We need the convenience that the cyberspace offers.Now we can save our time buying things through the Internet, but we lose the chance to talk with people face to face. And what we only get is spending more time on the Internet! It numbed our feelings. I don”t suppose an emoticon is better than a real smile, or a real hug. Because we human beings are made of flesh, not mental.
