In recent years, with the development of technology, many popular apps have been produced. These days, an app has 【小题1】(catch) great attention. It is Douyin, a video sharing app. Douyin 【小题2】 (one)appeared in 2016. Now it is many people's favorite app,       【小题3】(especial) the young.

With Douyin, users can record videos, edit(编辑）them and share them online. It is very easy and interesting. We can record our videos with our friends with just a tap on the mobile phone 【小题4】 [ skriːn]. What's more, it's a great way to spend our free time 【小题5】browsing (浏览）through those film videos.

【小题6】, every coin has two sides. The app also has bad things. Some people spend long hours on the app, which is 【小题7】 to their health. What's 【小题8】 (bad), users can also find some bad things on the app. Such thing is unsuitable and meaningless.

In my opinion, Douyin should monitor videos before they are uploaded(上传)，in【小题9】       [ˈɔːdə(r)] to keep a healthy environment for its users. Douyin is not good for 【小题10】[ˈtiːneɪdʒəz]. We should not use it too often.
