英语单词have在造句时用不用加助动词

How many books dose he have?

可加可不加

当他表示动词“有”时，在疑问句等句式中就需要加助动词“does ”或“do”
How many books dose he have？在这句话中，就加了助动词“does”

have 表示“有”的意义时否定和疑问可用助动词，也可以不用。但多用助动词
I have some books.
Have you any books?
Do you have any books?
I have not any books
I don't have any books.
How many books dose he have?
