用法說明
How is "Valid" different from similar structures?What usage mistakes are common with "Valid"?
valid doing vs valid to do
- 在正式或法律文件中，"valid doing" 的結構（如 "a valid signing of the contract"）強調的是行為本身的合法性或有效性。
- "valid to do" 的結構（如 "It is valid to sign the contract"）則更常被用來表達做某事的權利或資格是有效的。
- 在描述一個程序或方法是否有效時，兩種結構都可能出現，但 "valid doing" 更側重於已完成的動作，而 "valid to do" 更側重於動作的可行性。
對比範例： EN: His notarized signature is a valid signing of the document. 翻譯: 他經過公證的簽名是對該文件的有效簽署。
EN:You are valid to sign the document as the legal representative.
翻譯:你作為法定代表人有資格簽署這份文件。
EN:The court ruled his claim a valid filing before the deadline.
翻譯:法院裁定他的索賠是在截止日期前的有效提交。
EN:Is it still valid to file an appeal after 30 days?
翻譯:30天後再提出上訴還有效嗎？
總結建議
在正式文書中描述已完成的合法行為用 "valid doing"，而說明某人具備做某事的有效資格或權利時，則用 "valid to do"。

正式寫作注意：在學術或正式商業文件中，應避免將「valid」用於上述口語的語氣強調或停頓填充情境。在正式文體中，它應嚴格用於描述論點、方法、數據或法律文件的「有效力、有根據」，例如「a valid hypothesis」（有效的假設）或「a valid contract」（有效合同）。
