有关系代词who引导的分句, 如果作主语的 who 之后跟有 believe, I think 等插入语，后面通常用主格
will you go and see Carlos, who I believe will be glad to help you?
She is a woman who people believe may be the esident of the company some day
第一句我感觉很像i believe是who的定语，但是第二句话如果是定语就差关系词了，那么怎么分辨插入语和定语的区别了，为什么又要用主格了，如果没有插入语者后面的woman who可以用whom吗
