语境与语域Context & Register
语域：formal 常见场景：冶金/材料科学、疫苗/医学 作形容词时，killed 多用于专业技术语境，如 killed steel（脱氧钢）或 killed vaccine（灭活疫苗）。日常口语中较少这样用，通常会说 inactivated 或 deoxidized 等更明确的词。
发音与拼写Pronunciation & Spelling
这些词都与 killed 一样押 /ɪld/：filled、skilled、chilled、grilled、build、guild。拼写警示：child /tʃaɪld/ 和 mild /maɪld/ 看起来像 -ild，但元音是 /aɪ/，不押韵；build 的 ui 读 /ɪ/，不要读成 /juː/。
