譯文：

• 鑒于TikTok推薦內(nèi)容的算法，外界廣泛認(rèn)為TikTok會使人上癮。該平臺已有五年歷史，在全球擁有逾10億用戶

詞匯：

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

知識點(diǎn)：

• because of its algorithm that recommends content【限定性定從】
• which is five years old and has more than a billion users around the globe【非限定性定從】
• 限定性定從一般是限定特質(zhì)是哪一類的先行詞，這種關(guān)鍵性的特征描述一般不可省略，否則會影響句意表達(dá)；
• 非限定定從只是補(bǔ)充說明先行詞有何性質(zhì)，通先行詞關(guān)系比較松散，不加沒事，加了更多是提示背景信息令邏輯更加自洽。
