1.?????? 社交媒体对网民的生活有很多积极作用，如加强与朋友、家人之间的联系，了解社会热点，获取知识等。不过，在带来便利的同时，社交媒体也给他们带来了困扰。这些困扰主要体现在三个方面：阅读时间减少，对睡眠、视力等健康方面产生影响以及对个人隐私带来安全隐患。值得注意的是，90后对社交媒体的负面影响有更强烈的感受，近四成90后表示会避免成为手机“奴隶”。

2.?????? Owned by Chinese tech giant Tencent, WeChat is a mobile messaging service that boasts over 300 million active users. Many former Weibo users join in as new members because it offers comparatively private forms of communication. Like many other Chinese social media platforms, WeChat allows its users to send voice messages, share social moments, purchase virtual goods, and meet new people via a format similar to that of chat roulette.
