含有have或has的句子如何变一般疑问句，否定句和对划线部分提问，动词原形的句子也是，明天就交

1.have/has 某人有某物，可直接做助动词
They have a happy family.
Have they a happy family?
They have not a happy family.

He has a brother.
Has he a brother?
He has not a brother.

2.have/has某人有某物，可做为普通的动词，需加助动词
They have a happy family.
Do they have a happy family?
They do not have a happy family.

He has a brother.
Does he have a brother?
He does not have a brother.
注：用了does，动词要还原为原形。

3.have/has构成的词组中，have/has一般视为普通动词，便文具盒否定句是，要加助动词

have breakfast
have a rest
have a meeting
have some medicine
have an exam
have a cold
have a holiday
have a visit

They have class in the morning.
Do they have classes in the morning?
They do not have classes in the morning.

He has a reast after school.
Does he have a rest after school?
He does not have a reat after school.

4.对划线部分提问
对划线部分提问题型，一定要用特殊疑问句，牢记（1）w词第一位 （2）助动词紧随其后

They have a happy family.
What have they?
或What do they have?

He has a brother.
What has he?
或 What does he have?

have与has都作“有”的意思讲，但二者的用法是有区别的。

在陈述句中，当主语是单数第三人称（he、she、it）时，句子的谓语是“有”时，用has；当主语是其他人称（I、you、we、they）时，句子的谓语是“有”时，用have。

例句：

I \ You have an apple .

We\They have some apples .

He\She has a pen .

但是，在疑问句中，当主语是就单数第三人称提问时用has，其它情况的“有”一律用have。。

例句：

Do you have a book ?

What does a cat have ?

What has a pouch?

是否定句
如果是don't have 一般疑问句以Don't you/we/I have开头
如果是doesn't have 一般疑问句以Does she/he/it have开头
如果是didn't have 一般疑问句Didn't you/she/he/it/we/I have开头
肯定句
就是你说的那样

Do you have a book ?What does a cat have? What has a pouch?

He hasn't eaten an apple
