喜欢英语的看过来

Does Mary have five pens?
No, she doesn't.
或者
Has Mary five pens?
No, she hasn`t.

正确的是:has,表示拥有，是个动词，对吧？
那么，在疑问句里，要对动词提问，就要用助动词：do或dose。mary是第三人称，就用does提问。然后把句子照搬一遍，即：
Dose Mary have five pens?---------No,she doesn't.
注意：有了助动词，动词dose变原形：do

Does Mary have five pens?
No, she doesn't.

Has Mary five pens?
No, she hasn`t.

does mary have 5 pens?
no, she doesn't

Has Mary five pens?
No, she hasn`t.

Does Mary have 5 pens?
No, she doesn't
