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.例:
They have a book.Have they a book?

have 和 has的用法(专项练习)

have和has与主语搭配情况:

I She

We He

You have… It has…

They The boy

Tony and Jenny Jenny

可见,主语为第三人称单数时用has,其余人称都用have。

have / has的含义及用法:

1.作“有”讲。 如:I have a bag. 我有一个包。

He has a red cup. 他有一个红杯子。

2.作“吃、喝”讲。如:have breakfast (吃早饭) have tea (喝茶)

have a biscuit (吃块饼干) have a drink (喝点水)

3.作“拿、取得、得到”讲。如:Can I have a toy? (我可以要一个玩具吗?)

somgthing,everything等用has,each of加名词用has,复数主语开头加each如they each仍旧用have.

二、根据汉语提示完成句子,使句意完整。

1. You have (有) two small eyes.

2. My sister has (有) three pens.

3.Come here and have (吃) an apple.

4.Mummy,can I have (要) a new bag.

三、下列句子均有一处错误,请圈出并改正。

1. I am have a green apple. 错:am 改: 去掉

2. Peter have a banana. 错:have 改:has

3. My brother and sister has a toy car. 错:has 改:have

4.They has got some roses. 错:has 改: have

5.She has got some lily. 错: lily改:lilies 或者some 改为a

一般现在时,主语是第三人称单数(he/she/it/Tom/my friend等等),动词用单三形式(have变has)。
have是原形,除了上面的情况以及过去时、完成时和现在时外,一般不变形。
