He is someone.Who is that man?的意思是那个男人是谁?
回答的结构应该是he主语加be动词is加那个男人的称呼或名称,也就是he is XXX。某人的英文是someone,所以回答的句子,整体结构可以是he is someone.he也可以用it代替,同样it is someone.
who is that man?的回答语是:he is my father.他是我的父亲。
Who is that man的意思是那个男人是谁?who是一个特殊疑问词,它的意思是谁。回答的时候,that man是一个单数形式,所以用代词he代替。例如,he is my grandfather.他是我的爷爷。He is my good friend.他是我的好朋友。
