用法說明
How is "Maintain" different from similar structures?What usage mistakes are common with "Maintain"?
maintain doing vs maintain to do
- maintain doing 並非標準英文用法。動詞 "maintain" 通常不直接接動名詞 (V-ing) 來表示持續進行某個動作。
- 若要表達「堅持做某事」或「持續做某事」，應使用 maintain that + 子句 來陳述一個主張或事實，或使用其他動詞如 "keep doing"。
- 結構 maintain to do 是錯誤的。"Maintain" 不是接不定詞 (to V) 來引導目的的動詞。
- 正確表達「維持某種狀態或活動」時，"maintain" 常接名詞作受詞 (如 maintain peace, maintain a car) 或接 that 子句。 EN: He maintains that exercising daily is essential for health. 翻譯: 他堅持認為每天運動對健康至關重要。
EN:He maintains his car regularly.
翻譯:他定期保養他的車。
總結建議
建議避免使用 "maintain doing" 或 "maintain to do"，正確用法是 "maintain + 名詞" 或 "maintain that + 陳述句"。
