用法說明
How is "Annul" different from similar structures?What usage mistakes are common with "Annul"?
annul + noun vs annul + that-clause
- annul + noun 是最常見的結構，直接接上被廢除的對象（如婚姻、合約、法律）。
- annul + that-clause 用於正式或法律文件中，具體說明被廢除的內容或決定。
- 動名詞結構（如 annul doing）極少使用，因為「廢除」的對象通常是既成事實或文件，而非一個持續的動作。
- 不定詞結構（如 annul to do）不符合英文慣用法，應避免使用。 EN: The court decided to annul the marriage due to fraud. 翻譯: 法院因詐欺而決定宣告這段婚姻無效。
EN:The judge ruled that the contract was annulled.
翻譯:法官裁定該合約已被撤銷。
總結建議
