    What's a blog? A blog is a personal online diary (日记). It's cool, it's hot, and everyone is doing it. People

talk about it often. Sound like a fashion? In fact, It's another trend (流行趋势). And the word "blogger" means

a person who writes diaries online. Are you a blogger?  

     Many bloggers are teenagers who log (进入) onto websites to discuss anything in their lives. Many of

today's teenagers are not afraid to openly discuss everything in their lives. Teenagers complain about their

parents and homework. They share diaries, post (发布) songs from the latest bands and show pictures of

theirs. They write their own poems, say something about their girlfriends or boyfriends and complain to each

other or offer support. But mostly they just write down what they do every day.  

     However, many parents are worried about these young bloggers. Parents see the kids talking about how

they got drunk last weekend and how they don't like studying. They are using the language that is surprising

to their parents. Besides hearing from their friends, teen bloggers also get messages from strangers. Most of

the time, it's older men asking to meet teenage girls. "These strange men are dangerous for my kids. They

sometimes teach my kids bad words." said Cara Cabral, a mother of two children.  

     Many teenagers and young adults know it's not safe to use blogs on the Internet. They know they are

putting information about themselves in a place where it can be seen by anyone. But teenagers are unwilling
