常見錯誤
What are common mistakes with "Bump"?Which "Bump" sentences look correct but are wrong?
×I bumped the wall.
✓I bumped into the wall.
當表示意外撞到靜止物體時，通常使用 "bump into" 這個片語動詞。單獨使用 "bump" 作為及物動詞時，語意較不自然，通常用於撞到身體某部位（如 bump my head）或使某物隆起。
×The car bumped with another car.
✓The car bumped into another car.
描述車輛等物體之間的輕微碰撞，應使用 "bump into"。使用 "with" 是錯誤的搭配。
×She bumped me on the street yesterday.
✓I bumped into her on the street yesterday.
表示偶然遇見某人時，固定使用片語 "bump into someone"。原句結構錯誤，且語意可能被誤解為物理碰撞。
×Can you bump the volume?
✓Can you turn up the volume?
"Bump" 在非正式口語中雖可表示「提高、增加」，但用於「音量」時並不自然，是受中文「調高」直譯影響的錯誤。應使用 "turn up" 或 "increase"。
×The road has many bumps.
✓The road is bumpy.
原句文法正確，但語意不自然。名詞 "bump" 指具體的隆起物。若要形容道路不平、顛簸的狀態，應使用形容詞 "bumpy"。
×He bumped the glass and the water spilled.
✓He knocked over the glass and the water spilled.
"Bump" 通常指輕微碰撞或震動，不一定導致物體翻倒。若要強調因碰撞而打翻，應使用 "knock over" 或 "tip over"。
