have/has的用法口诀
动词have表示“有”,
位置就在主语后。
“三单”主语用has,
其他人称用have。
一般问句句首do/does添。
否定句子也一样,
don’t /doesn’t主语后面站。
1.A dog has four legs.
2.Our school has a library.
3.We have 37 chairs in our classroom.
4.My sister has a nice toy car.
5.Does that girl have a doll?
6.Do Tom and his brother have a big bedroom?
7.I don'thave a model plane.
8.Lily doesn't have a doll.
Have与has的用法区别
have与has都是“有”的意思,但二者用法是有区别的。
在陈述句中,当主语是单数第三人称(he、she、it)时,句子的谓语是“有”时,用has;当主语是其他人称(I、you、we、they)时,句子的谓语是“有”时,用have。
例句:
I \ You have an apple .
We\They have some apples .
He\She has a pen .
但是,在疑问句中,当主语是就单数第三人称提问或否定句时用助动词does 和does not (doesn't),然后把has 变成have 如果不是第三人称,助动词就是do ,否定式do not (don't).特殊疑问句回答照样,该是has 还是has 该是have 还是have 但是当一般疑问句 以do或does开头的时候,只能回答 do dont 或者 does doesn't
例句:
Do you have a book ? yes ,I do /No , I don't
What does a cat have ? the cat has a ,,,,,,,
He doesnt have any coffee.
就是第二种:have本身也可以作为助动词,(作为完成时里的助动词)本身无词义
