学习提示Learner notes
记忆技巧Memory Tip
记忆联想：牙医（dentist）在诊所里“try”（尝试）钻研牙齿，所以dentistry是牙科学。
语境与语域Context & Register
语域：formal 常见场景：medical education、professional practice、career guidance 该词通常用于医学、学术或职业相关语境，比较正式；日常口语中相对少见，更常说 dental care 或去看牙医等表达。
发音与拼写Pronunciation & Spelling
这些词仅拼写或尾音相近，并非真正的韵词。Dentistry 读 /ˈdɛntəstri/，重读元音 /ɛ/，之后为 /ntəstri/；chemistry、ministry、registry、sophistry 虽都以 -istry 结尾，但重读元音及后续辅音不同，因此都不押韵。industry 的尾音也是 /stri/，但重读元音为 /ɪ/，也不押韵。请勿凭拼写将 -istry 一律读成 /ɪstri/。
