In recent years, with the development of technology, many popular apps have been produced. These days, an app has {#blank#}1{#/blank#}(catch) great attention. It is Douyin, a video sharing app. Douyin {#blank#}2{#/blank#} (one)appeared in 2016. Now it is many people's favorite app,    {#blank#}3{#/blank#}(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 {#blank#}4{#/blank#} [skriːn]. What's more, it's a great way to spend our free time {#blank#}5{#/blank#}browsing (浏览)through those film videos.

    {#blank#}6{#/blank#}, every coin has two sides. The app also has bad things. Some people spend long hours on the app, which is {#blank#}7{#/blank#} to their health. What's {#blank#}8{#/blank#} (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{#blank#}9{#/blank#} [ˈɔːdə(r)] to keep a healthy environment for its users. Douyin is not good for {#blank#}10{#/blank#}[ˈtiːneɪdʒəz]. We should not use it too often.
