常見錯誤
What are common mistakes with "Breach"?Which "Breach" sentences look correct but are wrong?
×He breached the contract.
✓He breached the contract.
雖然文法正確，但中文學習者常誤以為 'breach' 僅用於法律情境。實際上，'breach' 也可用於描述違反協議、信任或安全等更廣泛的語境。
×They breached into the system.
✓They breached the system.
'Breach' 作為及物動詞時，直接接受詞，不需介系詞 'into'。'Breach into' 是多餘且不自然的用法。
×He made a breach of the rules.
✓He committed a breach of the rules. / He breached the rules.
描述「做出違反行為」時，常見的動詞搭配是 'commit a breach'，而非 'make a breach'。更簡潔的說法是直接用動詞 'breach'。
×The water is breaching the dam.
✓The water is breaching the dam.
此句文法正確，但中文學習者可能混淆 'breach' 與 'break'。'Breach' 強調強行突破障礙或違反規定，帶有正式或嚴重意味；'break' 則泛指一般的打破、損壞或休息，用法更廣泛。在此情境下，'breach' 更精確。
×This action is a breach to the agreement.
✓This action is a breach of the agreement.
名詞 'breach' 後接違反的對象時，固定使用介系詞 'of'，而非 'to'。這是常見的介系詞搭配錯誤。
