每天一句长难句｜Tiktok“瘾”患——限定定从和非限定定从的区别

文本:

• TikTok, which is five years old and has more than a billion users around the globe, is widely described as addictive because of its algorithm that recommends content.

译文：

• 鉴于TikTok推荐内容的算法，外界广泛认为TikTok会使人上瘾。该平台已有五年历史，在全球拥有逾10亿用户

词汇：

• algorithm n【算法】
• described sth as +补语(n/adj/v-ing) SYN portray/ label sth as

知识点：

• because of its algorithm that recommends content【限定性定从】
• which is five years old and has more than a billion users around the globe【非限定性定从】
• 限定性定从一般是限定特质是哪一类的先行词，这种关键性的特征描述一般不可省略，否则会影响句意表达；
• 非限定定从只是补充说明先行词有何性质，通先行词关系比较松散，不加没事，加了更多是提示背景信息令逻辑更加自洽。
