No,he did never go there这句话对吗 急！！！

不一定要用完成时。
但No, he did never go there 不对。应该是
No, he never went there 或 he never did go there (这里的did是加强语气)

1.我可以百分之百确定这句话是对的。
did never经常出现的，在口语中。
比如说He did never see them again.
he did never taste it.
比较强调从未。
在国内的很少见到，因为毕竟是口语化的东西。

2.never不一定要用在完成事态的句子中。
可以用在将来式，I will never do it.
过去式，I never did it.
还有你所说的完成时，I have never been there.

不对。应该说He never went there。
never不一定用在完成时中，用在一般时也可以，例如
I never watch basketball games. 我从不看篮球赛。

对的，虽然正常情况下一般说成 he never went there. 但是为了强调的话，可以用助动词do表示强调，意思是是“他真的从没去过那”，看语境了，有没有必要这么表达

no ,he had never been there
