助動詞 do (do, does, did)

助動詞 do 可以幫助主動詞: (1)形成疑問句、 (2)形成否定句、(3)加强語氣、 (4)代替前面已提過的動詞,避免重覆使用。

形成疑問句

do
does
did
+ 主詞 + 動詞原式 + + ?

He likes pop music.

他喜歡流行音樂。

肯定句

若將上面句子改為疑問句,在主詞 He 之前加上助動詞 does, 並將動詞 likes 改為動詞原式 like。

Does he like pop music?

他喜歡流行音樂嗎?

形成否定句

do
does
did
+ not + 動詞原式

I like apple.

我喜歡蘋果。

肯定句

I don't like apple. (don't = do not)

我不喜歡蘋果。

動詞 like (喜歡) 藉由助動詞 do, 及副詞 not 的幫助,而形成否定句。

加强語氣

I do like this cake.

我的確喜歡這個蛋糕。

在正面的、肯定的句子,用助動詞 do 來加强語氣。

Please do come.

請一定要來。

助動詞 do 加强語氣,請務必要來,誠懇地邀請。

Never did I stop loving you.
(= I never stopped loving you.)

我從來沒有停止過愛你。

這種在副詞"never"後面加 do, does, did,把字的順序顛倒過來,也是為了加强語氣用。

I really do expect to be treated the way I treat you — with respect.

我真心期望你對待我就如同我對待你一樣 — 尊重。

助動詞 do 用來加强語氣。

代替前面已提過的動詞,避免重覆使用。

Jeff plays bridge, doesn't he? ~ Yes, he does.

Jeff 打橋牌,不是嗎? 〜是的,他是會橋牌。

does 代替 plays bridge。

The students ran out of the classroom and so did the teacher.

學生們跑出教室,老師也是如此。

did 代替 ran out of the classroom。did 與 ran 都用過去式。

Do 除了當助動詞外,也可以當主要動詞

Do
助動詞主要動詞
What does this word mean? ~ I don't know.
這個詞是什麼意思?~我不知道。
What do you do in your free time?
你空閒的時候在做些什麼?
Did you learn English at school? ~ Yes, I did.
你在學校學英語? ~是的,我學英語。
What are you doing now?
