举例说明如何把含有have和has的句子变成否定句

一种是助动词do
例子:
(1) I have an apple. 否定句：I do not have an apple.
(2) He has an apple. 否定句：He does not have an apple.
另一种是直接在have后面加not
例子：
(1) I have go to Wuhan. 否定句：I have not go to Wuhan.
(2) He has go to Wuhan. 否定句：He has not go to Wuhan.

I have a bag.
I don't have a bag.
He has a bag.
He doesn't have a bag.

如 I have a book. 变为否定句 则为 I don't have a book.即在have前加一个 don't。要是has加一个dosen’t。
如果have是现在完成时的标志时，则在它后直接加not
如 I have not eaten

I have big eyes.
改为：I don't have big eyes.

She has a small mouth.
改为：She doesn't have a small mouth.
