语域：mixed 常见场景：户外活动（追踪足迹）、物流运输（查询货物）、安全监控（定位目标）、音乐制作（录制歌曲）、教育领域（能力分组） 动词 track 的多个义项分布在不同场合，语气随搭配变化：表示“跟踪/追踪”时较正式；表示“录制（歌曲）”多用于音乐行业口语；表示“踩脏（地面）”则很口语。因此整体标记为混合，具体文体需根据上下文和搭配判断。
与 track /tɹæk/ 押韵的词有 back /bæk/、lack /læk/、pack /pæk/、crack /kɹæk/，它们都含 /æk/ 音。注意拼写相似的 trick /tɹɪk/ 和 truck /tɹʌk/ 虽然也以 -ck 结尾，但元音不同，读音与 track 不同。
