记忆技巧Memory Tip
记忆联想：down（向下）+ grade（等级）→ 等级往下走，就是降级、降低评级。
语境与语域Context & Register
语域：neutral 常见场景：financial credit ratings、employee performance reviews、software version changes 作动词时通常用于中性或正式场合，多见于金融评级、职位变动、软件版本调整等语境；也可表示“贬低、降低评价”。日常口语中也可使用，但整体语气偏正式。
发音与拼写Pronunciation & Spelling
这些词以 -grade 结尾或读音相似。其中 grade、upgrade（动词）、degrade 与 downgrade 的结尾读音相同，都是 /ɡreɪd/，可以押韵；centigrade、retrograde 虽然拼写也以 -grade 结尾，但重音在第一个音节，实际读音中的 -grade 不是重读音节，因此不与 downgrade 押韵。maid 拼写不同，但读音 /meɪd/ 与 downgrade 的结尾 /ɡreɪd/ 押韵。
