用法說明
How is "Proof" different from similar structures?What usage mistakes are common with "Proof"?
proof vs. proofed vs. proven
- proof 作為動詞時，主要意思是「使…防水/防…」或「校對」。其過去式和過去分詞有兩種常見形式：規則變化的 proofed 和不規則變化的 proven。
- 在表示「使防水/防…」或「校對」的具體動作時，proofed 是較為普遍且安全的選擇。
- 當用於被動語態或完成時態，強調「經過驗證的」、「被證實的」狀態時，proven 更為常見，尤其在一些固定片語中（如 a proven method）。
- 在美式英語中，proven 作為過去分詞的使用比在英式英語中更為廣泛。 EN: He proofed the manuscript for errors before sending it to the printer. 翻譯: 他在將手稿送交印刷廠前，先校對了一遍錯誤。
EN:The fabric has been proofed against water.
翻譯:這塊布料已經經過防水處理。
EN:This is a proven method to increase efficiency.
翻譯:這是一個經過驗證能提高效率的方法。
EN:The theory has not yet been proven.
翻譯:這個理論尚未被證實。
總結建議
在表示「使防水」或「校對」的動作時，建議使用 proofed；在表示「經過驗證的」狀態或概念時，proven 是更自然的選擇。
