用法說明
How is "Behave" different from similar structures?What usage mistakes are common with "Behave"?
behave oneself vs. behave (intransitive)
- behave oneself 是及物動詞片語，強調在特定場合下「守規矩、表現得體」，通常用於對兒童或晚輩的指令。
- behave 單獨作不及物動詞使用時，語意較廣，可指「（機器、物質等）正常運作」或「（人）表現出某種行為」，不一定帶有「守規矩」的含義。
- 在正式或強調禮儀的語境中，behave oneself 更為常見且精確。
對比例句： EN: Children, please behave yourselves at the wedding. 翻譯: 孩子們，在婚禮上請守規矩。

常見錯誤
What are common mistakes with "Behave"?Which "Behave" sentences look correct but are wrong?
×He behaved very good at the party.
✓He behaved very well at the party.
「behave」是動詞，修飾動詞應該用副詞「well」，而不是形容詞「good」。
×Please behave you.
✓Please behave yourself.
「behave」作為及物動詞表示「使（自己）舉止得體」時，必須使用反身代名詞（yourself, himself 等）。
×She behaved like a professional.
✓She behaved professionally.
雖然「behave like a professional」語法上正確，但更常見且地道的用法是使用副詞「professionally」來描述行為方式。原句可能被理解為「她模仿專業人士的樣子」，而非強調其行為本身專業。
×I will behave my best.
✓I will behave as well as I can. / I will be on my best behavior.
「behave」不能直接與「my best」搭配。正確的慣用說法是「be on one's best behavior」或使用「as well as I can」等副詞片語。
×This chemical behaves different under heat.
✓This chemical behaves differently under heat.
描述「behave」的方式，即化學物質如何反應，應使用副詞「differently」，而非形容詞「different」。
×He behaved that he was angry.
✓He behaved as if he were angry. / His behavior suggested he was angry.
「behave」後面不接「that」子句。要表達「表現得好像...」，應使用「as if」或「as though」引導的副詞子句。
