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.
【參考譯文】
現在我的許多同學都喜歡在空閒時間上網，我認為網際網路能給我們帶來好處和缺點。
例如，我可以上網學習更多關於世界的信息。我可以交更多的朋友。我也可以跟我的老師或同學一些問題反思。
然而，網際網路同時也會產生一些問題。如果你花太多時間在上面，你就會變懶，不能專心學習。如果你覺得沒有網際網路你就不能生活。
所以我們必須小心當我們使用網際網路。

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.
