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.

Dear friends,

I am writing this letter to draw your attention to the disasters（灾难）these days. Too much rain destroyed the crops and washed the earth away. Sometimes it was too little and made plants dead. Also there was too much dust in the air. All these did great damage to our life.

However, we made them! So it is time for us to try our best to save the Earth.

The most important thing is to plant trees as many as possible. At the same time, we should stop cutting down trees and protect the forests. And we can save our planet through many other ways, such as saving water and using both sides of paper. Besides, don't keep TVs or computers on when you are not using them. When you leave a room, turn off the lights.

A small action is very helpful to our planet. Please join us in the action of protecting the Earth. Let's start from the little things right around us.

Nowadays, more and more people begin to look for fun online. Watching livestreaming (直播的) shows has become part of their lives. At the same time, traditional culture has found a bigger stage online. Many traditional artists are starting to livestream on Douyin and Bilibili. Some of them sing Peking Opera, some show their folk handcrafts (手工艺), while others perform Chinese classical music. A growing number of people are becoming interested in traditional culture because of livestreaming.

Li Jun is a Peking Opera performer with the Shanghai Jingju Theater Company. After the outbreak(退休), the 59-year-old man took up his smartphone and started livestreaming. Unlike performing on a formal stage, Li uses ordinary places as his stage, including his backyard and study room. Apart from singing, Li also teaches audience about Peking Opera. People can ask him questions and get answers directly.

"Livestreaming has brought this elegant (高雅的) art down to earth. " one viewer said. "It gives young people an easier access to this traditional art and learn more about it. " Li has more than 6, 000 fans on Douyin, while one of his videos got 42, 000 views on Bilibili.

On March 26th, 2020, Bilibili livestreamed a Huafu show on the third China Huafu Day (中国华服日). Performers presented clothes in traditional Chinese styles, including those from Wei, Tang and Ming dynasties. During the show, viewers not only enjoyed looking at the clothes, but also watched how performers used ancient styles of make-up.

As Guangming Daily noted, livestreaming has come to a new stage through which traditional culture can be kept alive.
