语境与语域Context & Register
语域:formal 常见场景:neuroscience、pharmacology、physiology 该词是较正式的专业术语,通常见于神经科学、生理学和药理学等学术或临床语境;日常口语中不常用,多改用 stimulating 或 exciting。
发音与拼写Pronunciation & Spelling
这些词均以拼写后缀 -atory 结尾,英式发音中该后缀常读作 /ətəri/(美式常作 /ətɔːri/)。其中 explanatory、mandatory、preparatory、inflammatory 的重读元音都是 /æ/,但后续辅音不同,读起来并不押韵;且均不与 excitatory 构成真正押韵,因为 excitatory 的重音在第二音节 /saɪ/,读作 /ekˈsaitətəri/。特别注意 regulatory 的重音在第三音节 /leɪ/,读音与其余词差异较大。
