用法說明
How is "Did" different from similar structures?What usage mistakes are common with "Did"?
did + V 與 did + V-ing 的區別
- did + V (動詞原形) 是「did」最標準的用法，表示過去發生的單一、已完成的事件或動作。
- did + V-ing 則較為少見且特定，通常用於強調過去某個活動的「過程」或「經歷」，而非單一動作的完成。
- 在疑問句或否定句中，did + V 是唯一正確的結構，用來構成過去式的疑問或否定。
- 使用 did + V-ing 時，常帶有「花時間做了某事」或「經歷了做某事的過程」的含義。 EN: She did finish her homework before dinner. 翻譯: 她確實在晚餐前完成了作業。
EN:She did some gardening this afternoon.
翻譯:她今天下午做了些園藝工作。
EN:Did you call the client yesterday?
翻譯:你昨天打電話給客戶了嗎？
EN:He didn't go to the meeting.
翻譯:他沒有去開會。
總結建議
在絕大多數情況下，使用「did + 動詞原形」來表達過去發生的動作或事件是最清晰且正確的選擇。

引述
在口語中，常用 "did" 來引述或重複對方剛說過的話，以表示確認、驚訝或尋求澄清。 EN: A: "I told him the truth." B: "You did?" 翻譯: A: "我跟他說了實話。" B: "你真的說了？"

EN:"He did try his best, even if the result wasn't perfect."
翻譯:"他真的盡力了，即使結果不完美。"
停頓填充

EN:"The last time I saw him, he was... did... working at a cafe, I think."

書寫注意：上述所有口語用法，尤其是「停頓填充」和用於「引述」的簡短問句（如 "You did?"），在正式書寫（如報告、論文、商業信件）中應避免使用，應改為結構完整、語氣正式的句子。
