have和has的用法區(qū)分
have 是動詞原形i have,we have,you have,they have,to have...
has 是第三人稱單數(shù)時用 he has,she has,it has

have/has的句型轉(zhuǎn)換
1.否定句
主語+don't (doesn't)+have +….例:
We don't have any water here.我們這兒沒有水.
This wall doesn't have a window in it.這面墻上沒有一個窗戶.
2.一般疑問句:
Do (Does)+主語+have+…?
肯定回答:Yes,主語+do (does).
否定回答:No,主語+don't (doesn't).例:
—Do you have a ruler?你有尺子嗎?
—Yes,I do ./No,I don't.是的,我有./不,我沒有.
—Does Lucy have a twin sister?露茜有個孿生姐姐嗎?
—Yes,she does./No,she doesn't.是的,有./不,沒有.
注意:do,does是助動詞,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,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,一般不用于進行時態(tài).
另外,在現(xiàn)代英語中,當(dāng)“有”講時,have/has的一般疑問句可以把have/has直接提前,當(dāng)have/has作助詞時表示完成時態(tài)時也可以直接提前.例:
They have a book.Have they a book? oll?
