求这两句英语的否定句，疑问句，疑问句的肯定回答，否定回答。

Question

He hsa short hair.
His hair is short
说一下方法，详细一点

Answer 1

has是助动词have的第三人称单数形式，am，is，are是系动词，知否?知道这个就简单了。

否定句;第一句有两种方法，一种直接在助动词后面加not.
He has not short hair.
另一种是在has前面几doesn't ，然后has还原成have.
He doesn't have short hair.
疑问句：在句首加does ，has还原成have.
Does he have short hair？

第二句：
否：系动词is后面加not.
His hair is not short.
疑：系动词is提前.
Is his hair short？

Answer 2

否定句在助动词后加not
疑问句吧助动词提前
He has not short hair.
Does he have short hair? Yes, he does. No, he doesn't.

His hair is not short.
Is his hair short? Yes, it is. No, it isn't.追问

有的句子没有助动词啊

Answer 3

否定句：He doesn't have short hair.
His hair isn't short.
疑问句：Does he have short hair? Yes,he does. No he doesn't.
Is his hair short? yes,it is. No,it isn't.追问

方法说一下

追答

否定一个句子：有Be动词就直接在Be动词后面加not，没有Be动词就加助动词do或does，再加 not。
疑问句是一样的，有Be动词就提前，没有就加助动词do或does。
