关于宾语从句结构问题如果说what's the matter 是陈述语序 那像 why is it ,who is th

what引导一个宾语从句 what's the matter with him,原本就是陈述句语序.如：He told me what's the matter with him.
what是主句的宾语成分,同时引导一个定语从句,是定语的主语.what=it that
What's the matter比较特殊,在从句中就是现在这个顺序.
其他的在从句中要转化为陈述句
why it is , who the new one is是陈述语序,而 why is it , who is the new one是疑问句语序
