has 是单数第三人称
eg: He has so many books.
She has 2 brothers.
It has 4 legs.
have 用于除第三人称以外的人称。
eg:
We have many soccer balls.
They have 3 tennis rackets.
do / does 和否定式结构
否定句:主语+ don't( doesn't ) +动词原形(+其它)。如:
I don't like bread.
当主语为第三人称单数时,要用doesn't构成否定句。如:
He doesn't often play.
一般疑问句:Do( Does ) +主语+动词原形+其它。如:
- Do you often play football?
- Yes, I do. / No, I don't.
当主语为第三人称单数时,要用does构成一般疑问句。如:
- Does she go to work by bike?
- Yes, she does. / No, she doesn't.
祝学习进步!
