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 possible problems 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 communicate with 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.

A. students could be put into unreal situations on the Internet

B. teenagers are facing unknown dangers on the social networks

A. the dangers are similar when chatting online and surfing social networks

Last week, 169 students at No.35 Middle School of Shenyang took their first no-teacher exam. After the teacher handed out the exam paper, he left the room and never came back. A student collected in the papers when the exam ended.

   “That test was not only a test of knowledge, but also a test of moral (道德). We wanted to show students how important honesty is, ” said Mr. Cai, the school’s headmaster. The school says no cheating happened in the test. Next year, it wants 80% of its exams to be without teachers. But students have different ideas.

    “I was happy and excited during the exam because my teachers trusted me,” said Lang Yudan, a 13-year-old girl in Class 11.

“Schools must trust students a lot not to use invigilators(监考人). But I think it is too early. Some students will cheat if there are no invigilators. And the students will not be able to ask for help when needed,” said Hua Sha.

    “I don’t like having invigilators in exams. When they walk around the classroom, they make me nervous. I would get higher marks without them in the room because I would feel more relaxed,” Liu Qingxi said.

    “I think it’s very important to have invigilators in exams. Many students want to check their answers with each other after they have finished papers. And they can also keep the classroom in order when something unusual happens. They may make me nervous, but I still think we need them,” Shangguan Yan said.

Not using invigilators may be a good idea. But before using it, schools must tell students the importance of honesty and try to find ways to solve something unusual in exams.

Draw a giraffe in your mind. How did you draw your giraffe? Does it have a long neck? Does it have long legs? Is it really tall? When people think of giraffes, they think of their long necks.
