如题所述
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,和do 一样,has 就相当于does 在单三情况下用, 主要用于构成各种时态、语态、语气以及否定和疑问结构。(那此时的have还是has就要看具体的人称而定)完成时态是have/had + done (过去分词的形式)
I have finished my work, she has finished her work
have you finished your work? has she finished her work? 在一般疑问句里回答直接用have/has
yes,i have/ No , i haven't Yes, she has/ No, she hasn't(因为这里have/has是助动词)
have和has的用法:
1、have和has与主语搭配:主语为第三人称单数时用has,其余人称都用have。
2、have和has的意思有:有的,“吃、喝”,“拿、取得、得到”。

I have finished my work, she has finished her work
have you finished your work? has she finished her work? 在一般疑问句里回答直接用have/has
yes,i have/ No , i haven't Yes, she has/ No, she hasn't(因为这里have/has是助动词)
has 是第三人称单数时用 he has, she has, it has
have用于第一人称(I, we),第二人称(you), 及第三人称复数(they);has用于第三人称单数(he, she, it)或单数名词。
1. have的用法总结
(1)have作“有”讲,强调“所属关系”,含有“拥有”之意。其主语一般是人,有时也可以是物。
They have many new books. 他们有许多新书。
Wei Hua has a little brother. 魏华有个小弟弟。
This table has four legs. 这张桌子有四条腿。
(2)have可以作“买”讲。
I want to have a kilo of beef. 我想买一公斤牛肉。
May I have a new pen? 我可以买支新笔吗?
(3)have作“用、使用”讲
Excuse me, may I have your bike, please? 打扰了,我可以用(借用)你的自行车吗?
(4)have+表示动作的名词(这类名词常由同形的动词转化而来),意为“做(某事)”(=do sth. )。
have a drink (of…) 喝一点(……)
have a look(at…) (朝……)看一眼
have a rest 休息一下
have a swim 游泳
这些短语常用于口语,这里的have可以用take替换。
(5)have+表示一日三餐的名词,意为“用餐”。
have breakfast/lunch/supper 吃早饭/午饭/晚饭。have dinner吃饭,吃晚饭。
(6)have+表示食品、饮料等的名词,意为“吃;喝”(=eat, drink)。如:
have(some) bread 吃面包
have eggs(for breakfast) (早餐)吃鸡蛋
have(a cup of )tea 喝(一杯)茶
这里的have也可以用take替换。
(7)have+表示某种活动的名词,意为“进行;举行”。如:
have a class (学生)上课
have a sports meeting 开运动会
have a party 举行聚会
(8)have+表示疾病的名词,意为“患(病)”,有时也用have got。
have a bad cold 患重感冒
have (got) a cough 咳嗽
have(got) a headache 头痛
(9)have+表示一段时间的名词,表示“经历;度过”。
have a good time 度过快乐的时光,玩得愉快
have a good summer holiday度过愉快的暑假。
(10)have意为“邀请;招待”。
Thank you for having me. 感谢你们邀请我。
We are having friends for dinner. 我们要请朋友们吃饭。
2. have/has的句型转换:
(1)否定句
主语+don't (doesn't)+have +…。例:
We don't have any water here. 我们这儿没有水。
This wall doesn't have a window in it. 这面墙上没有一个窗户。
(2)一般疑问句:
Do (Does)+主语+have+…?
肯定回答:Yes, 主语+do (does).
否定回答:No, 主语+don't (doesn't). 例:
—Do you have a ruler? 你有尺子吗?
—Yes, I do . /No, I don't. 是的,我有。/不,我没有。
—Does Lucy have a twin sister? 露茜有个孪生姐姐吗?
—Yes, she does. /No, she doesn't. 是的,有。/不,没有。
注意:do,does是助动词,do用于第一、二人称单、复数和第三人称复数;does用于第三人称单数形式。回答一般疑问句时,主语用人称代词表示;否定回答中don't或doesn't 一般不分开写。
注意:have (has)表示“有”时,一般不用于进行时态。
另外,在现代英语中,当“有”讲时,have/has的一般疑问句可以把have/has直接提前,当have/has作助词时表示完成时态时也可以直接提前。例:
They have a book. Have they a book?
3. “have”与“there be句型”的区别
have意为“有”,指所属关系;there be表示“某地有某物”,意指“存在”。例:
There's a book on the desk. 桌子上有本书。
Xiao Wang has an English-Chinese dictionary. 小王有本英汉字典。
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,和do 一样,has 就相当于does 在单三情况下用, 主要用于构成各种时态、语态、语气以及否定和疑问结构。(那此时的have还是has就要看具体的人称而定)完成时态是have/had + done (过去分词的形式)
I have finished my work, she has finished her work
have you finished your work? has she finished her work? 在一般疑问句里回答直接用have/has
yes,i have/ No , i haven't Yes, she has/ No, she hasn't(因为这里have/has是助动词)呵呵呵呵😄
