用法說明
How is "Defend" different from similar structures?What usage mistakes are common with "Defend"?
defend doing vs defend to do
- defend doing 是正確且常見的用法，表示「為（某個已發生的）行為辯護或辯解」。
- defend to do 在標準英語中是錯誤的，動詞 "defend" 後面不接不定詞 (to + V) 來表示辯護的動作。
- 若要表示「為某人做某事而辯護」，應使用 defend someone for doing something 的結構。
- 動詞 "defend" 的基本句型是 defend someone/something (from/against someone/something) 或 defend doing something。 EN: She defended leaving early, saying her work was finished. 翻譯: 她為提早離開辯護，說她的工作已經完成了。
EN:He defended his colleague for making that difficult decision.
翻譯:他為同事做出那個困難的決定而辯護。
總結建議
使用 "defend doing" 來表示為某個行為辯護，避免使用 "defend to do"。
易混淆對比

引述
在轉述他人說法或為自己辯護時，常用來引述防衛的立場或理由。 EN: He was quick to defend himself, saying, "I had no other choice." 翻譯: 他立刻為自己辯護，說道：「我別無選擇。」

EN:You don't have to defend your opinion so passionately; we're just having a discussion.
翻譯:你不必如此激動地捍衛你的觀點；我們只是在討論。
停頓填充
在思考如何解釋或辯護時，可能會用 "I mean, to defend..." 或 "Well, defend..." 作為填充語，引出後續論點。 EN: His actions were questionable, but—I mean, to defend him a bit—he was under a lot of pressure. 翻譯: 他的行為是有問題，但是——我的意思是，稍微為他辯護一下——他當時壓力很大。
EN:The plan has flaws. Well, defend it as best you can in the meeting tomorrow.
翻譯:這個計畫有缺陷。嗯，明天開會時盡你所能為它辯護吧。
正式寫作注意：在正式或學術寫作中，應避免使用上述口語化的停頓填充結構（如 "I mean, to defend..."）。建議使用更直接、結構清晰的表述，例如 "One might argue in his defense that..." 或 "A point in defense of this policy is..."。

常見錯誤
What are common mistakes with "Defend"?Which "Defend" sentences look correct but are wrong?
×He defended the enemy.
✓He defended himself from the enemy.
「defend」的對象通常是需要保護的人、事物或地點，而不是攻擊者。若要表達對抗敵人，應使用「defend (someone/something) from/against the enemy」。
×I must defend my opinion to my boss.
✓I must defend my opinion to my boss. / I must justify my opinion to my boss.
雖然「defend」有「辯護」之意，但用於為觀點、決定辯護時，語意較強，常暗示該觀點受到挑戰或攻擊。在較中性的情境（如解釋理由）中，使用「explain」或「justify」可能更自然。但原句在語法上正確，只是語用上可能過強。
×She is good at defending.
✓She is good at defending. / She is good at defense.
「defend」作為及物動詞時通常需要賓語。單獨使用「defending」雖然在特定上下文（如體育評論）中可能出現，但較不完整。更自然的說法是明確指出防禦的對象，或使用名詞「defense」。原句語法並非完全錯誤，但顯得不自然。
×They defended the castle during three years.
✓They defended the castle for three years.
表示一段時間的持續動作，應使用介系詞「for」，而不是「during」。「during」後接的是某個事件或時期，強調在該時間段內發生某事。
×I will defend you to solve this problem.
✓I will help you (to) solve this problem.
「defend」的意思是「保護、防衛、辯護」，沒有「幫助（做某事）」的含義。想表達協助之意，應使用「help」。這是因混淆單字基本詞義而產生的錯誤。
×The company defended from the financial crisis.
✓The company defended itself from the financial crisis. / The company weathered/survived the financial crisis.
「defend」作為及物動詞，若主語是承受保護動作的實體，常以反身代名詞（itself, themselves）作賓語，形成「defend oneself from/against...」結構。或者，根據語意，使用更貼切的動詞如「weather」或「survive」。
