預(yù)約高中1對1精品課程(面授/在線),滿足學(xué)員個(gè)性化學(xué)習(xí)需求 馬上報(bào)名↓
1. 到底何時(shí)使用did?
did和其它助動(dòng)詞一樣,本身無意義,自己不能獨(dú)立作謂語,只能和其它主要?jiǎng)釉~一起構(gòu)成謂語,用于構(gòu)成一般過去時(shí)的否定句和疑問句,當(dāng)然也常常用于代替上文中的行為動(dòng)詞的過去式。如:
I didn't go to school last Sunday. 上周日我沒上學(xué)。
Did you buy a new pen yesterday? 昨天你買了枝新鋼筆嗎?
2. did身后的動(dòng)詞到底用什么形式?
有的小朋友總不注意did身后的動(dòng)詞用什么形式,在否定句和疑問句中,
did身后的動(dòng)詞必須用原形。 “他昨天沒有在家吃午飯。”
[誤] He didn't had lunch at home yesterday.
[正] He didn't have lunch at home yesterday.
3. 我能用be動(dòng)詞代替嗎?
不管怎么說,含有行為(實(shí)義)動(dòng)詞的一般過去時(shí)的肯定句變成否定句或疑問句時(shí),不能用be動(dòng)詞,必須用到did!含be動(dòng)詞的句子構(gòu)成否定句或疑問句都絕不會(huì)讓
did露面! 例句:They went to the park last week. (改為否定句)
[誤] They weren't go to the park last week.
[正] They didn't go to the park last week.
