用法說明
How is "Has" different from similar structures?What usage mistakes are common with "Has"?
has done vs has to do
- has done 是現在完成式（Present Perfect）的結構，表示動作在過去發生，但與現在有關聯或影響現在。
- has to do 是情態動詞片語，表示「必須做」某事，強調必要性或義務。
- 兩者的否定形式意義完全不同：hasn't done 是「還沒做」；hasn't to do 或更常見的 doesn't have to do 是「不必做」。
- 疑問句結構也不同：Has she done...? 詢問經驗或結果；Does she have to do...? 詢問是否有義務。
對比範例： EN: She has finished her report. 翻譯: 她已經完成她的報告了。
EN:She has to finish her report by 5 PM.
翻譯:她必須在下午五點前完成她的報告。
對比範例： EN: He has visited Japan three times. 翻譯: 他去過日本三次。
EN:He has to visit Japan for work next month.
翻譯:他下個月必須去日本出差。
總結建議
區分關鍵在於 has done 描述「已完成」的經驗或結果，而 has to do 則表達「必須做」的義務或要求。

口語用法

引述
在轉述他人說過的話或想法時，口語中常用 "has" 來保持時態一致，即使主句是過去式。 EN: She said she has already finished the report. 翻譯: 她說她已經完成報告了。
EN:He told me he has never been to Japan.
翻譯:他告訴我他從沒去過日本。
語氣強調
在口語中，可以透過重讀 "has" 來強調動作的完成或狀態的持續，帶有「確實已經」的語氣。 EN: She HAS seen the email, she just hasn't replied yet. 翻譯: 她「確實已經」看到那封郵件了，只是還沒回覆。
EN:I know he HAS the ability to do it.
翻譯:我知道他「確實有」能力做這件事。
停頓填充
在思考或組織句子時，有時會用 "has" 作為短暫的停頓填充詞，後面再接上真正要說的主詞和動詞。這種用法較不正式。 EN: So... has... the meeting been rescheduled? 翻譯: 所以…那個…會議改時間了嗎？
EN:Has... anyone called about the delivery?
翻譯:有…有人打電話來問送貨的事嗎？
正式寫作注意：上述口語用法，特別是「停頓填充」和過於隨意的「引述」時態混用，在正式書面語、學術寫作或商業文件中應避免，以保持語言的嚴謹與清晰。

常見錯誤
What are common mistakes with "Has"?Which "Has" sentences look correct but are wrong?
×He have a new car.
✓He has a new car.
當主詞是第三人稱單數（he, she, it 或單數名詞）時，現在式助動詞必須用 has，而不是 have。
×Did he has finished his homework?
✓Has he finished his homework?
在現在完成式的疑問句中，應直接將助動詞 has/have 移到句首，不可在前面再加 did。
×This is has book.
✓This is his book.
has 是助動詞或動詞，表示「有」或構成完成式。表示「他的」所有格應使用 his，不可用 has。
×He has seen the movie yesterday.
✓He saw the movie yesterday.
現在完成式（has + 過去分詞）不能與明確的過去時間副詞（如 yesterday, last week, in 2020）連用。若有明確過去時間，應使用簡單過去式。
×He doesn't has a phone.
✓He doesn't have a phone.
在否定句中，若使用助動詞 does/doesn't，後面的主要動詞必須用原形 have，而不是第三人稱單數形式的 has。
×I lived here for five years. (and I still live here now)
✓I have lived here for five years.
當描述從過去持續到現在的狀態或動作時（常與 for, since 連用），應使用現在完成式 has/have + 過去分詞，而不是簡單過去式。
