写一篇关于网络安全的博文
假定你是李华，最近某论坛正在举行以“学生应关注网络安全”为主题的讨论，请你结合自己的经验,根据提示内容写一篇博文发表在该论坛上: 认识；2.措施；3.号召。
Nowadays, with the development of the Internet, more and more middle school students like surfing the Internet, playing games, chatting with friends online. I’m one of them.
One day, I found my personal information stolen. It is not safe online. So I think we should pay attention to online safety. First, we’d better not share our personal information on the Internet. Never reveal or send our passwords to anyone. Besides, don’t use unhealthy websites anytime.
In a word, do be careful when using the Internet. At the same time, everyone should take measures to protect our networks from being misused and attacked.
如今，随着互联网的发展，越来越多的中学生喜欢上网、玩游戏、和朋友在线聊天。我就是其中之一。
有一天，我发现我的个人信息被盗。它在网上是不安全的。所以我认为我们应该注意网络安全。首先，我们最好不要在互联网上分享我们的个人信息。永远不要向任何人透露或发送我们的密码。此外，任何时候都不要使用不健康的网站。
总之，使用互联网时一定要小心。与此同时，每个人都应该采取措施保护我们的网络不被滥用和攻击。
