現在完成式的基本句型為: 主詞 + have / has + 過去分詞 (動詞第三態, 又稱 p.p.) (第三人稱單數的主詞用 has )
否定句: 主詞 + haven’t / hasn’t + p.p.
疑問句: Have / Has + 主詞 + p.p.?
或 疑問詞(What / Where / Who / How long…) + have / has + 主詞 + p.p.?
p.p. 是動詞第三態, 規則動詞就是和過去式一樣加 ed , 像 watched, learned, studied
不規則動詞拚法會變, 像 go 就變成 gone, know 變成 known 等
很多課本最後會有附錄, 字典也會有, 不知道的字可以去查
現在完成式用在以下三種情況:
(1) 從以前持續到現在的動作或狀態 (重點是到現在還有或還是這樣; 若現在 沒有, 只有以前用, 就會用過去簡單式)
例: I have worked here for two years. 我已經在這裡工作兩年
He has been busy in the past three days. 他過去三天裡(到現在為止)一直都很忙
(2) 此生到目前為止的經驗
例: Have you (ever) been to France? 你去過法國嗎?
Jack has never gone ice-skating. Jack 從來沒溜過冰
(3) 到此刻為止”已經...”, “還沒...” (否定句)
例: I have (already) had dinner. 我已經吃過飯了
We haven’t seen that movie (yet). 我們還沒看過那部電影
其他注意事項:
不論是肯定, 否定, 疑問句都要用過去分詞, 不能用原形動詞
ever (曾經) 只能用在疑問句; 肯定句的”已經”用 already 這個字, 但可以省略, 因為現在完成式本身就已經是”已經...”的意思了
yet 用在否定句表示”還沒...”, 用在疑問句表示”...了沒?” 但也可以省略, 要用的話就放句尾
現在完成式的句子後面常會用 for / since + 時間, 表示持續多久(for) 或從何時開始(since)
for 後面要接一段時間的長度, 如 two weeks, three years
since 接開始的時間起點, 如 1995, last week, high school, I was 10 (years old)
have / has been to… 是”去過...地方”, 而 have / has gone to… 是”出發前往...了”
