问题补充：

He is not native; if he were, we this discussion over his identity.

A. would not be having

B. are not having

C. had not had

D. will not have

答案：

(答案→)A. would not be having

B. are not having

C. had not had

D. will not have

解析：考查虚拟语气。从if he were可知，与现在相反，故主句应该使用would/could/should/might+动词原形，故选A，隐含进行。句意：他不是本地人，如果是的话，我们就不会还在讨论他的身份。
