It’s the end of class.When the bell rings, students of Luohu Foreign Languages School in Shenzhen quickly take out their telephones.They want to log on to their micro blogs (登录到他们的微博) to check the interesting things.They want to see what have happened in the last hour.

Since several years ago, more and more people have used micro blogs in our country.Recent surveys (调查) shows that most students in middle schools have a micro blog and some even update (更新) their blogs over five times per day.

“We learn many fresh and interesting things on micro blogs and they have become popular topics in class,” said Kitty Jiang, 14.“If you do not know about them, you are out of loop.” It is also a great place for students to say something about themselves.“My parents always ask me to study hard, and encourage me before exams, but it really gives me pressure (压力),” said Alan Wang, 15.“I share these feelings on my micro blog.My friends always give me answers in the same situation.This makes me feel better.”

But parents worry that micro blogging could be a waste of time.Some unhealthy information may even bring danger to kids, they said.

Mr Shen, a professor (教授) asks parents not to worry too much as long as kids are not crazy about micro blogging.Maybe it can become a window for parents to understand their children.“If parents can read their children’s micro blogs, they’ll know what they think, they can know more about their children and help them solve their problems,” he said.He also gives some advice for kids.

-Don’t micro blog for more than one hour a day.

-Never micro blog in class.

-Try to talk face to face with people from time to time.

-Don’t believe all the information on a micro blog.

Recent research from the Pew Internet Project suggests that 90% of Americans aged from 12 to 17 use the Internet, and 51% of those teens use social networks. However, there are many possibleproblems with social networking sites and the teenagers who use them.

Apart from the social advantages, social networking sites can be used to record school research, develop artistic talents and experiment with other forms of subject creation. They provide a way to communicatewith others who share the same interests and to get helpful advice on ongoing projects.
Along with these advantages come some dangers. For example, most social networking sites are open to all, especially MySpace, which is the most popular social network among teens in America. It means that they could be put in unpleasant and frightening situations.
A greater danger is that teens may become objects of the people with secret purposes. The secrecy of some social networking sites makes it easy for dangerous people to find young teens and invite them into dangerous conversations. It’s easy for them to pretend as teens and draw children into dangerous real-world communication as well. Then further hurt might be on its way.
Another danger is identity stealing, which can happen when teens share too much information about their names, dates of birth and locations.
Therefore, it’s very important to make sure teens are safe when they use social networks.
Many of the same rules that work for online chat work for these sites:
※Don’t use your real name.
※ Don’t give out personal information to people you don’t know. A last name and a town
are enough for a bad guy to find where you are.
※ Don’t believe that people are who they say to be.
※ Immediately end any communication that makes you uncomfortable and report it to a
parent.
Only if you are sure of your safety, can you enjoy the fun brought by social networking. Besides, trying to deal with all problems on your own can lead to terrible results. Remember, asking your parents or school officials for help doesn’t mean you are unable to do anything but wiser than many others.
