Learner notes
Memory Tip
记忆：/skʌm/ 像“似刮沫”，汤面浮沫叫 scum，用勺轻轻“刮”掉这层，动作就是动词 scum。
Context & Register
语域：formal 常见场景：cooking: removing scum from boiling broth or jam、industrial: skimming surface impurities from liquid in tanks、environmental: clearing scum from ponds or wastewater 作为动词，scum 多用于书面或技术性较强的语境，指撇去液体表面的浮渣或使表面结出浮渣；日常口语中更常说 skim (off) the scum，因此这里按正式用法标注。
Grammar Note
及物动词，后接宾语
Pronunciation & Spelling
发音上，scum 与 drum、sum、hum、glum、thumb 押韵，均为 /ʌm/（thumb 的 -umb 拼写中 b 不发音）。注意拼写形似的 scam /skæm/（元音为 /æ/）和 skim /skɪm/（元音为 /ɪ/）发音不同，勿混淆。
