PREP08 SC 190 关于主谓宾和同位语问题，等牛们解答！

190.
The thirteen original British colonies in North America, some formed as commercial ventures, others as religious havens, each had a written charter that set forth its form of government and the rights of the colonists.
A. some formed as commercial ventures, others as religious havens, each had a written charter
B. some being formed as a commercial venture, others as religious havens, all of which had written charters
C. some that formed as commercial ventures, others as religious havens, all had written charters
D. with some being formed as a commercial venture, others as religious havens, all had a written charter
E. with some formed as commercial ventures, while others as religious havens, each had a written charter

prep08笔记上解说A. Correct；some formed as commercial ventures, others as religious havens做为the thirteen original British colonies in North America的同位语，each为the thirteen original British colonies的同位语

我的疑问是，这个句子看起来，应该是each是主语，had是谓语，那是不是应该是the thirteen original British colonies是each的主语同位语呢？还是说同位语这种结构对于双方是可以互相转换的？而且这里each又不是独立主格结构……我就乱了……

谁能详细帮我剖析一下结构的么？先谢过了……

把some。。。havens都去掉，each是指13个colony的每一个，作为修饰13个colony的成分不能算做主语吧，主语还是13个colony。我觉得prep里的解释可能写错了，不管是独立主格还是同位语都不能是一个完整的句子，只能是fragment。所以each had肯定不是独立主格或同位语。但是，我对each 到底是什么成分也有困惑，觉得可能是形容词。
prep08-116india那道题，each a product of regional influences感觉是同位语，修饰前面的many different styles of cooking, 所以each是名词性成分就是pronoun，所以用单数。。。。同位语和独立主格的区别manhattan上说是前者修饰它之前的名词，后者不用符合这个规则而是修饰整句话。所以觉得india这题应该是同位语不是独立主格。。。个人观点，非N

这道题我也不明白，这些都是什么结构。
some formed 和 others as 是什么成分?
我感觉formed是分词修饰，做定语修饰前面的主语，
others as又是什么成分? 只能说是修饰鱼的同位语。
然后，这题的谓语是had
那么。each又是什么成分? 只能说它是主语的同位语。
