have和has-用法 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,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 是动词原形i have,we have,you have,they have,to have... 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 (1have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. (2have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? (3have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. 1 / 2 have和has-用法 (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.
