小夥伴們,大家是不是經常看到do,does,但是有時候不小心會用錯呢?
下面來做一些do,does用法說明。
說明一: do 的第三人稱單數形式是does。
說明二:它的用法大體上從兩方面來講。
一、 作為行為動詞,跟其他動詞一樣,比如study, play等。它的意思是「做」的意思。
We usually do our homework in the afternoon.
He does his homework in the evening.
二、 作為助動詞,也就是幫助主要動詞構成否定和疑問等。
請留意:這類句子是有實義動詞的句子。
1. 當主語是I,we, you及第三人稱複數時,在謂語動詞前加do not (= don’t)
I don’t know it.
They don’t have two volleyballs.
Tina and Tom don’t like ice cream.
2. 當主語是第三人稱單數時,在謂語動詞前加does not (= doesn’t), 謂語動詞用原型
She doesn’t have a set of keys.
He doesn’t know my name.
Tom doesn’t need a computer game.
3、變一般疑問句採用「一加二變三問號」得方法
一加
l 當主語是I, we,you及複數時,在句子開頭加do;
l 當主語是第三人稱單數時(第三人稱包括she, he, it, this, that,單獨的事物或者人名等), 在句子開頭加does。
二變
l 第一人稱變為第二人稱(I / we變為you, my / our變為 your); l 當主語是第三人稱單數時,謂語動詞要用原型。
三問號
在句末加問號。
肯定回答;Yes, 主語 + do/ does.
否定回答:No, 主語+don’t / doesn’t . (主語要用相應的人稱代詞主格)。
I know it. => Do you know it?
Yes, I do. No. I don't.
They have two volleyballs. => Do they have two volleyballs?
Yes, they do. / No, they don’t .
Tina and Tom like ice cream. => Do Tina and Tom like ice cream?
Yes, they do. / No, they don’t.
She has a set of keys. => Does she have a set of keys?
Yes, she does. / No, she doesn’t.
He knows my name. => Does he know your name?
Yes, he does. / No, he doesn’t.
