3 . Do you know which social app is popular with Chinese young people now? “Short videos”are certainly the most popular. A large number of young people use Tik Tok (抖音) and Kuaishou. They think it is fun to share their lives by short videos, while others have other purposes as well.

A 12-year-old user named Elsa has about 2.7 million fans on Tik Tok. The girl has shared her dancing studies on Tik Tok since last July. One of the videos won her about one million fans.“I feel really glad to share happiness with people by short videos,” said Elsa.

To some other young people, they use short videos to have a quick look at the hot programs. “Because I don’t like to spend many hours watching a whole program, I hate waiting for a program to end, and I prefer to watch short videos of wonderful parts of hot programs,” said Wang Zhihao.

However, some young people feel bored with short videos.“Killing time is the main reason for me to watch short videos, and many short videos are almost the same, so I think they are not so useful or interesting. What’s more, I really don’t like the videos about strange and dangerous things,” said Wen Nan, another college student.

Recently, something else has appeared. Some videos are telling people what commodities are worth buying. Some short videos even sell bad commodities, and it is hard for customers to get their money back. So we should think twice before we want to buy the commodities by short videos.

In recent years, with the     1     of technology, many popular apps（应用程序）have been produced. These days, an app has caught great attention. It is Douyin, a video sharing app. Douyin first     2     in 2016. Now it is many people’s favorite app,     3     the young.

With Douyin, users can record videos, edit（编辑） them and     4     them online. It is very easy and interesting. We can share our videos with our friends with just a tap on the mobile phone screen. What’s more, it’s a great way to spend our free time by     5     through those funny videos.

However, every coin has two     6    . The app also has bad things. On the one hand, some people spend long hours on the app, which is     7     to their health. On the     8     hand, users can also find some bad things on the app. Such things are unsuitable and meaningless.

In my opinion, Douyin should check the videos     9     they are uploaded（上传）in order to keep a     10     environment for its users.

Douyin is not good for teenagers. We should not use it too often.

As some videos are about the latest news a group of users depend on them to get information.

From QQ to microblog to Wechat, it’s easy for us to connect with     1     another in many ways. But this kind of     2     has come a set of digital etiquette (数码礼仪).

As new research by BT Mobile and Oxford University noted, “It’s as important to treat people     3     online as it is in real life.” The study came up with rules of etiquette in the digital age. It has     4     three notices for you. Please take a look.

First, don’t share too much on the Internet. Some of us are not     5     enough to show off our thoughts and lives on social networking sites. Another annoying (令人讨厌的) way to overshare is     6     sharing, reposting and giving advice on other people’s thoughts, pictures, videos and articles.

Second, don’t gossip (闲聊) about people on social media.

Gossip on social media can be     7     than in real life, so it’s better to be     8     about it.

So we should wish people a happy birthday by calling them     10     as well as leaving messages on social media.
