Question

nobody 在反义疑问句主句中出现时，短句主语是什么？

按说前一个正确？No one knows about it, do they? 可是后一个是易错题研究时给出的正确答案诶No one knows you here, does he?

Answer 1

当前面句子中的主语是everybody, nobody, somebody, everyone, no one ,someone, nothing, something时，反义疑问句中的代词用they。当前面句子中的主语为anything, everything, nothing, something 时,反义疑问句中的代词用it。

没有人在这次事故中受伤，是不是？
Everything seems all right, doesn't it?
一切似乎都正常，是吗？

Answer 2

it，一般不确定都用it
