记忆技巧Memory Tip
想象质数（prime number）像首相（prime minister），都是“第一”：质数是最基本的数，全盛期是最佳时期。
语境与语域Context & Register
语域：neutral 常见场景：life stages、career discussions、sports commentary 作为名词，通常指人生或事业中精力最旺盛、成果最多的时期，常出现在 in one's prime、the prime of life 等短语中。语气中性，较常见于传记、访谈、体育评论等语境。
发音与拼写Pronunciation & Spelling
与 prime /praɪm/ 押韵的词包括 time、crime、lime、climb、rhyme，它们都含 /aɪm/ 音（注意 climb 的 b 不发音，rhyme 拼写不同）。但要小心 prim /prɪm/，它拼写相近却读短音 /ɪ/，并不押韵；primer 作“入门读物”时读 /ˈprɪmər/，作“底漆”时读 /ˈpraɪmər/。
