occur to someone vs occur doing
- occur to someone 是常見的片語，表示「某人突然想到（一個想法、念頭）」。主詞通常是「想法」，後面接
to + 人。 - occur doing 的結構並不自然，因為 "occur" 本身不直接接動名詞 (V-ing) 來表示「發生在做某事的過程中」。若要表達此意，應使用其他結構，如 "happen while doing"。
- 另一個相關結構是 It occurs to someone that...，用於引導一個完整的子句，說明想到的具體內容。 EN: A brilliant idea occurred to her while she was showering. 翻譯: 她洗澡時突然想到一個絕妙的主意。
EN:An accident occurred while they were hiking.
翻譯:他們健行時發生了一起意外。
總結建議
使用 "occur to someone" 來表達「某人突然想到」，而描述事件在另一動作過程中發生時，應避免使用 "occur doing"，改用 "occur while doing" 或其他動詞如 "happen"。
易混淆對比

「occur」較正式且多用於描述事件、想法或現象的發生，常與特定時間、地點或情境連用；「happen」則更口語、通用，強調偶然性或意外性。

「occur」可指自然或意外事件，也可指抽象事物（如想法）的出現；「take place」通常指事先計劃或安排好的事件發生。
occur vs arise
「occur」側重事件或想法在特定時間、地點的「發生」或「出現」；「arise」則強調問題、機會或狀況的「產生」、「起源」或「出現」，常帶有從無到有或由某原因引發的意味。

常見錯誤
What are common mistakes with "Occur"?Which "Occur" sentences look correct but are wrong?
×An accident was occurred yesterday.
✓An accident occurred yesterday.
"occur" 是不及物動詞，不能用於被動語態。它描述事件「發生」，本身就有主動發生的意思。
×I occurred a good idea.
✓A good idea occurred to me.
"occur" 的主語通常是事件、想法或現象，而不是人。表達「某人想到...」應使用 "occur to someone" 的結構，且主語是「想法」。
×The event will occur in 3 p.m.
✓The event will occur at 3 p.m.
表示事件發生的具體時間點，應使用介系詞 "at"，而不是 "in"。"in" 用於較長的時段，如月份、年份或季節。
×This word occurs many times in the article.
✓This word occurs many times in the article.
此句文法正確，但學習者常誤將 "occur" 與 "happen" 完全等同。"occur" 更正式，且常用於描述規律性或特定情境下的事件，而 "happen" 較口語，多用於意外或具體事件。在非正式口語中，用 "happen" 更自然。
×It's occur that we need more data.
✓It occurs to me that we need more data.
表達「某人想到...」時，不能直接用 "It's occur"。正確結構是 "It occurs to someone that..." 或使用 "It occurs that..."（較正式，主語為情況）。原句混淆了結構且動詞形式錯誤。
