have和has的用法區分
have 是動詞原形i have,we have,you have,they have,to have...
has 是第三人稱單數時用 he has,she has,it has
have用於第一人稱(I,we),第二人稱(you),及第三人稱複數(they);has用於第三人稱單數(he,she,it)或單數名詞.
have/has的句型轉換
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.這面牆上沒有一個窗戶.
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：

—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用於第一、二人稱單、複數和第三人稱複數;does用於第三人稱單數形式.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,一般不用於進行時態.
另外,在現代英語中,當“有”講時,have/has的一般疑問句可以把have/has直接提前,當have/has作助詞時表示完成時態時也可以直接提前.例：
They have a they a book?
3.“have”與“there be句型”的區別
have意爲“有”,指所屬關係;there be表示“某地有某物”,意指“存在”.例：
