帮忙分析一下gmat长难句中这句话comprising的作用Islam,on the other hand,represented a radical breakaway from the Arab paganism that preceded it； Islamic law is the result of an examination,from a religious angle,of legal subject matte
1.第一句比较简单,从第二句开始分析：
Islamic law is the result of an examination,[from a religious angle,] of legal subject matter that was far from uniform,
这句主语是Islamic law ,框里的是插入语,an examination 其实是跟后面的of legal subject 连在一起的
2.comprising [as it did] the various components and numerous legal elements
comprise + n."由……组成'',comprising 是现在分词作伴随状语,它的逻辑主语是Islamic law
as it did 是插入语,这里相当于as it comprised （before）,可以不用管它.
comprising 后面的宾语是the various components 和numerous legal elements
（题目里的括号是你自己加的吧?你加个括号说明你自己分得清这里的结构了,我就不讲了）
3.上翻译~
Islam,on the other hand,represented a radical breakaway from the Arab paganism that preceded it；
从另一方面来说,伊斯兰教代表了与它之前的阿拉伯异教的彻底决裂
Islamic law is the result of an examination,from a religious angle,of legal subject matter that was far from uniform,
从宗教角度看,伊斯兰法是/ 经过/ 对混乱不清的法律问题进行考察后/ 形成的结果
comprising as it did the various components (of the laws of pre-Islamic Arabia)
它（的主要内容）一直是由前伊斯兰阿拉伯法律的各种不同部分……
and numerous legal elements (taken over from the non-Arab people of the conquered territories.
以及/ 从被占领地的非阿拉伯人民那里继承的大量法律因素组成的
