语境与语域Context & Register
语域：formal 常见场景：科学或科普文章中描述极光、新闻报道或气象栏目、旅游类内容（如极光摄影、极光旅行） “aurora”指极光时，多用于较正式或书面化的语境，如科学文章、新闻报道和旅游文案；日常口语中更常说“northern lights”或“polar lights”。
语法说明Grammar Note
可数名词，复数形式为auroras；指极光或曙光女神时通常作专有名词，但常见义项为可数。
发音与拼写Pronunciation & Spelling
Rhyme group (same stressed vowel /ɒː/ followed by /rə/): aura, flora, Dora, senora. Watch out for lookalikes: aural /ˈɒːrəl/ adds a final /l/, and corona /kəˈrəʊnə/ has a different final vowel, so neither rhymes with aurora /ɒːˈrɒːrə/.
