一般疑问句的肯定回答：Yes, 人称代词+does。
否定回答：No, 人称代词+doesn’t. 如：
She has small eyes.
---She doesn’t have small eyes.
---Does she have small eyes?
---Yes, she does. /No, she doesn’t.
2) 当主语为除第三人称单数之外的人称:变否定句,在动词前加don’t;变一般疑问句,在句首加do,肯定回答:Yes,人称代词+do.否定回答:No,人称代词+don’t.
They have small eyes.
---They don’t have small eyes.
--- Do they have small eyes?
---Yes, they do. / No, they don’t.

形容词性物主代词 my your his her our their its
名词性物主代词 mine yours his hers ours theirs its
