常見錯誤
What are common mistakes with "Guard"?Which "Guard" sentences look correct but are wrong?
×He guards the door to not let anyone in.
✓He guards the door to prevent anyone from entering.
中文直譯「不讓...」常導致 'to not let' 的冗餘結構。正確用法是使用 'to prevent (someone) from (doing something)' 或 'to keep (someone) out' 等更自然的英語表達。
×I must guard my computer virus.
✓I must guard my computer against viruses.
'Guard' 作為及物動詞時，其受詞通常是被保護的對象（如人、地點、物品）。若要表達「防範...」，需使用 'guard (something/someone) against (something)' 的結構。
×She is guarding from the cold wind.
✓She is guarding herself against the cold wind.
當主語是保護自己時，需使用反身代名詞（如 myself, yourself, herself）。僅用 'guard from' 不完整且不自然，標準用法是 'guard (oneself) against'。
×The dog guards the house very well.
✓The dog guards the house effectively. / The dog is a good guard dog.
中文常用「很好」修飾動詞，但英語中 'very well' 修飾 'guard' 較不自然。更地道的說法是使用副詞 'effectively', 'vigilantly' 或改變句型。
×Can you guard my bag for a minute? I need to go to the restroom.
✓Can you watch my bag for a minute? I need to go to the restroom.
'Guard' 暗示正式、嚴肅或危險情境下的保護（如衛兵、防範攻擊）。在日常請人「暫時看管」物品的語境中，使用 'watch' 或 'keep an eye on' 更為自然。
