关于嵌入式关系分句的问题~

斑马王子蹄蹄

今天在kaogmat上面看之前做的错题，里面有个题目是这样的
Scholars who once thought Native American literatures were solely oral narratives recorded by missionaries or anthropologists now understand this body of work to consist of both oral literatures and the written works of Native American authors, who have been publishing since 1772.

A.Scholars who once thought Native American literatures were solely oral narratives
B.Scholars thinking of Native American literatures once solely as oral narratives, and
C.Scholars who once had thought of Native American literatures solely as oral narratives and
D.Native American literatures, which some scholars once thought were solely oral narratives
E.Native American literatures, which some scholars once, thinking they were solely oral narratives

题目解答下面有一个补充说明嵌入式关系分句。如下。
关于嵌入式关系分句—by tankobe：
OG12-118. The world wildlife fund has declared that global warming, a phenomenon most scientsts agree to be caused by human begings in burning fossil fuels, will create havoc among migratory birds by altering the enviroment in ways harmful to their habitats.

a) A phenomenon most scientists agree to be caused by human beings in burning fossil fuels,
b) a phenomenon most scientists agree that is caused by fossil fuels burned by human beings,
c) a phenomenon that most scientists agree is caused by human beings' burning of fossil fuels
d) which most scientists agree on as phenomenon caused by human beings who burn fossil fuels,
e) which most scientsts agree to be a phenomenon caused by fossil fuels burned by human beings
查了很多贴（国内和国外），对C选项的解释都是半斤八两，看得我一头雾水！（为什么一个定语从句里有两个动词agree和is）

一个普遍的误读是：说most scientists agree 是插入语，虽然是没加逗号！（此解释绝对是误人子弟！！！）



今天我翻遍章振邦的《新编英语语法》（CD上有下载），在1193—1395页赫然发现一个语法词条——嵌入式关系分句，详解如下：



"有一种关系分句（即定语从句），它既是先行项的后置修饰语（即定语），同时又是另外一个分句结构的宾语（即宾语从句）"此分句结构就被嵌入在定语从句中，即嵌入式关系分句。

该书举例：In his breast-pocket he had a patch of scarlet, which i suppose was the paper cap serving as a handkerchief.

注意两点：
从句which was the paper cap serving as a handkerchief 首先是 patch of scarlet的定语从句。
从句which（patch of scarlet） was the paper cap serving as a handkerchief 也是i suppose 的宾语从句，即I suppose （that）the patch of scarlet was the paper cap serving as a handkerchief 。
综上所述，但一个定语从句同时是另一个主谓结构的宾语从句是，就可以写为嵌入式关系分句。

我想问，之前说some scholars thought是嵌入式关系分句。在这个句子中嵌入的部分是some scholars thought吗？那它是谁的定语从句，谁又是它的宾语呢？

希望大家能解答我的疑惑~谢谢~~

Scholars who once thought（that） Native American literatures were solely oral narratives
who 后为schoolars的定语从句
that 后为宾语从句，此处省略

就是个从句嵌套的结构吧，不用太纠结于语法的某种叫法和用法啦。。。懂意思和用法就行啦
