育才学习网1.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。
2.写出5个have和has的陈述句和否定句
I have a cat. I don't have a dog.
He has a cap. He has not a hat.
She has an apple. She doesn't have an orange.
We have black eyes. We don't have blue eyes.
The rabbit has two long ears. It hasn't wings.
3.has在否定句中需要还原吗
如果当have/has表示“有”的时候，2113他是一个实意动词5261，如果要变成否定4102必须在前面加don't，同时否定句1653中三单要还原为原形 。
而一般疑问句中要说：Do you have。/Does he have。才是正确的。
如果have/has是助动词，那么 一般陈序句 变疑问句或者变否定句时，have/has 不变。
表示“有”时，haven't/hasn't和don't have/doesn't have都可以。
表示“吃、玩”时，用don't have/doesn't have。
表示助动词时，haven't/hasn't和don't have/doesn't have都可以。
扩展资料：
have/has的句型转换：
(1)否定句
主语+don't (doesn't)+have +…。例：
We don't have any water here. 我们这儿没有水。
This wall doesn't have a window in it. 这面墙上没有一个窗户。
(2)一般疑问句：
Do (Does)+主语+have+…？
肯定回答：Yes， 主语+do (does).
否定回答：No， 主语+don't (doesn't). 例：
—Do you have a ruler？ 你有尺子吗？
—Yes, I do . /No, I don't. 是的，我有。/不，我没有。
—Does Lucy have a twin sister？ 露茜有个孪生姐姐吗？
—Yes, she does. /No, she doesn't. 是的，有。/不，没有。
注意：do,does是助动词，do用于第一、二人称单、复数和第三人称复数；does用于第三人称单数形式。回答一般疑问句时，主语用人称代词表示；否定回答中don't或doesn't 一般不分开写。
注意：have (has)表示“有”时，一般不用于进行时态。
另外，在现代英语中，当“有”讲时，have/has的一般疑问句可以把have/has直接提前，当have/has作助词时表示完成时态时也可以直接提前。
