manhattan 里说： the possessive nouns can serve as antecedents only to possessive pronouns
什么意思阿？？

possessive nouns 是象jonhn's 这样的
那 my your his her it's our their whose 算possessive nouns 吗？

那这意思是这些词只能对mines yours hers his ours theirs ?
糊涂了

就是很多错题里面经常会出现比如：
John's sister is young, so he always helps her with her homework. --> Incorrect。这里的he是不能指代前面所有格里面的John.
John's sister is young, but she can go to school by herself. -->Correct。这里的she可以指代John's sister.

M的意思是说： 名词所有格中的名词，只能作为物主代词的指代对象 (如果用一般代词，就会改变指代对象，比如LZ例子2中的she就指代sister了)  

举个例子  The professor collected the students' assignments to check out whether they understood the lecture well.  这个句子就不正确， 因为they错误指代assignments

The professor collected the students' assignments to compare them with their notes.   这个句子是正确的  their指代students ; them指代assignments
