has與have的用法與區(qū)別什么
has與have都是“有”的意思,但二者用法有所區(qū)別，下面學(xué)習(xí)啦小編為大家介紹關(guān)于has和have 的用法及相關(guān)英語知識(shí)，歡迎大家閱讀。
has與have的用法與區(qū)別
在陳述句中,當(dāng)主語是單數(shù)第三人稱(he、she、it)時(shí),句子的謂語是“有”時(shí),用has;當(dāng)主語是其他人稱(I、you、we、they)時(shí),句子的謂語是“有”時(shí),用have.
如：
I \ You have an apple .
He\She has a pen .
We\They have some apples .
在疑問句中,當(dāng)主語是就單數(shù)第三人稱提問或否定句時(shí)用助動(dòng)詞does 和does not (doesn't),然后把has 變成have 如果不是第三人稱,助動(dòng)詞就是do ,否定式do not (don't).特殊疑問句回答照樣,該是has 還是has 該是have 還是have 但是當(dāng)一般疑問句 以do或does開頭的時(shí)候,只能回答 do dont 或者 does doesn't
如：
Do you have a book ?yes ,I do /No ,I don't
have本身也可以作為助動(dòng)詞,(作為完成時(shí)里的助動(dòng)詞)本身無詞義,和do 一樣,has 就相當(dāng)于does 在單三情況下用,主要用于構(gòu)成各種時(shí)態(tài)、語態(tài)、語氣以及否定和疑問結(jié)構(gòu).(那此時(shí)的have還是has就要看具體的人稱而定)完成時(shí)態(tài)是have/had + done (過去分詞的形式)
如：
I have finished my work,she has finished her work
have you finished your work?has she finished her work?在一般疑問句里回答直接用have/has
yes,i have/ No ,i haven't Yes,she has/ No,she hasn't

(1)否定句
主語+don't (doesn't)+have +….例：

肯定回答：Yes,主語+do (does).
否定回答：No,主語+don't (doesn't).例：

—Yes,I do ./No,I don't.是的,我有./不,我沒有.
—Does Lucy have a twin sister?露茜有個(gè)孿生姐姐嗎?

注意：do,does是助動(dòng)詞,do用于第一、二人稱單、復(fù)數(shù)和第三人稱復(fù)數(shù);does用于第三人稱單數(shù)形式.回答一般疑問句時(shí),主語用人稱代詞表示;否定回答中don't或doesn't 一般不分開寫.
注意：have (has)表示“有”時(shí),一般不用于進(jìn)行時(shí)態(tài).
另外,在現(xiàn)代英語中,當(dāng)“有”講時(shí),have/has的一般疑問句可以把have/has直接提前,當(dāng)have/has作助詞時(shí)表示完成時(shí)態(tài)時(shí)也可以直接提前.例：
They have a book.Have they a book?
“have”與“there be句型”的區(qū)別
have意為“有”,指所屬關(guān)系;there be表示“某地有某物”,意指“存在”.例：
There's a book on the desk.桌子上有本書.
