举例说明如何把含有have和has的句子变成否定句
例1：I have a pen.
I have a pen.
have用于除第三人称单数外的人称实义动词,变否定句不能在have后加not,则需要助动词来帮助解决.do+not= don’t.
例2：My father has a watch.
My father doesn't have a watch.
has 用于第三人称单数外的人称实义动词,变否定句不能在has后加not,则需要助动词来帮助解决.does+not=doesn't
注：变第三人称单数是,要注意动词部分的还原.

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.

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.

例子：
(1) I have go to Wuhan. 否定句：I have not g...

收起

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
