先问下牛牛们谁有代词指代的详细讲解链接，麻烦给。 最好也包括定冠词之类的 谢谢！ 因为上课的时候老师没说这部分 自己复习的白勇书上也木有！

In a 5-to-4 decision, the Supreme Court ruled that two upstate New York counties owed restitution to three tribes of Oneida Indians for the unlawful seizure of their ancestral lands in the eighteenth century.

(D) on two upstate New York counties that owed restitution to three tribes of Oneida Indians because they unlawfully seized
(E) on the restitution that two upstate New York counties owed to three tribes of Oneida Indians for the unlawful seizure of
答案A
第一题中A选项they 为什么我不能说他指代large investors?而必须得指代前面句子的主语？
第二题中未划线的their为什么我不能说他指代two upstate NY counties?而去指代three tribes of OI？ 相应的错误选项B中their为什么就不能说他指代的thress tribes of OI？而去指代two upstate NY counties?      刨去句意理解 代词指代不都有歧义么？
代词指代的问题有原则么 比如优先指代主句主语之类的？还是必须根据句意来判断？

The proposed urban development zones do not represent a new principle; it was employed in “Operation Bootstrap” in Puerto Rico.

(A) do not represent a new principle; it
(B) represent not a new principle, but one that
(C) are not a new principle; the same one
(D) are not a new principle, but one that
(E) are not new in principle;
答案B
B中but one that...结构是定从修饰的短语么？
还有that 省了不是更简洁么？but one was employed...虽然是句子 但这不是but引导的让步的从句？

Astronomers at the Palomar Observatory have discovered a distant supernova explosion, one that they believe is a type previously unknown to science.
(A) that they believe is
(B) that they believe it to be
(C) they believe that it is of
(D) they believe that is
(E) they believe to be of
答案E
E中one they believe to be of 是不是倒装的形式？ 可以写成they believe one to be of么？

码字好辛苦 码了字不小心点了X重新码更辛苦 所以希望牛牛们能帮帮忙！！！万分感激！！！

第一题因为逗号前后是主从句的关系，主句主语（从句主语）优先指代从句主语（主句主语）。这是一种结构上的规则
第二个题，LZ还是从句以上理解吧，逻辑上their只能指代Oneida Indians
第三题but前后是两个宾语的并列：represent not a...but one that...  one后面that引导定语从句修饰one，one指代zones。not but是平行结构的连接词，前后应该对称
第四题，one they believe to be 就是一个比较常用的英语用法，不算是倒装吧，感觉上有点像传说中的“嵌入式分句”。。。可以肯定的是整个结构是对explosion的同位修饰。
