助记：quarantine 谐音“跨人停”：为防传染把人拦下，隔离观察。
语域：mixed 常见场景：government health notices、medical records、daily conversation quarantine 的语域比较灵活：正式场合（如政府公告、医疗文件）中通常作名词，指隔离措施或隔离期；日常口语中作动词也很常见，表示“隔离”。因此这里标记为 mixed，具体使用时需根据语境判断。
真正的押韵词（重读元音及其后发音相同）有 routine（/ruˈtin/）、canteen（/kænˈtin/）、fifteen（/ˌfɪfˈtin/）、between（/bɪˈtwin/），它们都以重读的 /in/ 收音。注意 guillotine 虽然也以 -tine 拼写，但通常读作 /ˈɡɪlətin/，末尾不重读，故不算严格押韵；quarter 只是开头的 quar 拼写和 /kwɔr/ 发音相近，整体发音不同。
