among them ..在句子里是什么用法?among them后面怎么能跟三个名词连用?
his book is organized around a few central themes,among them the basic causes of misleading statistics,"mutant statistics"and promble in comparisons.

among them.这是一个独立主格结构做伴随状语来补充补充说明.在这个结构中,没有真正的主语和谓语动词.
他的书围绕着几个中心主题来组织结构,其中的主题有错误数据产生的基本原因,“畸形数据”和比较中存在的问题.独立主格?怎么结构是介词加代词再加名词?独立主格结构应该是名词加非谓语啊?among them 就相当于主语,后面一大串名词就是非谓语。。要是改成并列句的话就是his book is organized around a few central themes AND among them ARE the basic causes of misleading statistics,"mutant statistics"and promble in comparisons.In the course of designing a structure,you have to take into consideration what kind of load the above mentioned structure will be subjected,where on the structure the said liad will do what is expected .能否分析一下第一个what从句内部的结构,第二个what从句中what的意思,我经常译成“什么”似乎不对。这两个what都是引导的宾语从句Take sth into consideration..其中sth就是做宾语,由于此句话中的是一个由what引导的宾语从句,为避免头重脚轻而把它放入句末。第二个what可根据语境引申为与期待结果等等。。。我不太明白“liad”是什么意思?-.-
