核心語法：現在完成時
一、核心概念圖解
現在完成時連接過去與現在，表示：
已完成動作對現在的影響
持續狀態從過去延續至今
![時間軸圖示]（建議補充圖示：左側標"過去"，右側標"現在"，中間用箭頭連接）
二、結構公式
句式 結構 例句
肯定句 主語 + have/has + 過去分詞 I have seen that movie.
否定句 主語 + haven't/hasn't + 過去分詞 She hasn't finished her work.
疑問句 Have/Has + 主語 + 過去分詞 Have you eaten breakfast
注意：
第三人稱單數用 has（he/she/it）
規則動詞：V-ed（played, worked）
不規則動詞需單獨記憶（go→gone, see→seen）
三、四大核心用法
1. 已完成經歷（Ever/Never）
Have you ever been to Beijing
I have never tried sushi.
2. 剛剛完成的動作（Just/Already）
She has just left.（剛離開，現在不在）
We have already had lunch.（現在不餓）
3. 持續狀態（For/Since）
They have lived here for 10 years.（仍住在這里）
I have known her since 2020.（至今仍認識）
4. 重復動作（Several times）
He has visited Paris three times.
四、標志性時間狀語
類型 關鍵詞 例句
不確定時間 already, just, yet, recently I have already done it.
經歷詢問 ever, never, before Have you ever ridden a horse
持續時長 for + 時間段, since + 時間點 She has worked here since 2018.
次數統計 once, twice, ...times We have met twice this month.
禁區警示：
不能與明確過去時間連用（yesterday, last week）
正確：I have finished my homework.（未說何時完成）
錯誤：I have finished my homework yesterday.
五、易錯點突破
1. 延續性 vs. 非延續性動詞
動詞類型 示例 正確用法 錯誤用法
延續性動詞 live, work I have lived here for 2 years. -
非延續性動詞 buy, die I have had this car since 2020. have bought
轉換技巧：
buy → have, die → be dead, come → be here
2. have been to vs. have gone to
表達 含義 例句
have been to 曾去過（已回） She has been to Tokyo.
have gone to 已去某地（未回） Tom has gone to London.
3. 與一般過去時對比
現在完成時 一般過去時
強調現在影響 僅說明過去
I have lost my keys.（現在找不到） I lost my keys yesterday.（僅陳述事實）
六、記憶口訣
"現在完成時，過去連如今，
have/has加過分，already/yet要記清。
for接時間段，since跟時間點，
非延續動詞需轉換，been/gone別混淆！"
