原句：
And it especially must be highly regarded by people who are themselves admired.
不理解的是 people who are themselves admired，who are (themselves) admired，被动不都是be done的形式吗，这个为啥要在be 和done的中间插入个themselves？很突兀!
Themselves在这个句子里面做的是主语的同位语。
第1个助动词之后，是同位语的正常位置。
比如all作同位语，They were all defeated。
再比如第一助动词是情态动词的，Sentences have parts, which may themselves have parts 句子由不同部分组成，而这些部分本身又可能由（更小的）部分组成。（CGEL）
