og127关于修饰对象的问题！！！

127. In theory, international civil servants at the United Nations are prohibited from continuing to draw salaries from their own governments; in practice, however, some governments merely substitute living allowances for their employees' paychecks. assigned by them to the United Nations.

(A)  for their employees' paychecks, assigned by them

(B)  for the paychecks of their employees who have been assigned

(C)  for the paychecks of their employees, having been assigned

(D)  in place of their employees' paychecks, for those of them assigned

(E)   in place of the paychecks of their employees to have been assigned by them

In choice A, the phrase assigned by them modifies the adjacent noun, paychecks: the sentence implies that paychecks, rather than employees, work at the United Nations.

不是说分词在句尾，当前面有逗号的时候做状语修饰主句主语吗？

这里为什么说可以修饰paychecks作定语？？？

请教大家！

我的意思是，C的having been assigned明显不是伴随结果，所以只能是第（1）种情况，但是修饰governments也不对

但是如果这么说的话那A中的也是“assigned”也是分词，前面有逗号，位于句尾，可肯定不是伴随结果。

那为什么可以作定语修饰逗号前面的paychecks？

如果按照楼上的说法岂不是解释不通？

请教！

-ed分词短语在句尾，一般优先就近作定语，修饰名词。（白勇《GMAT语法全解》）

其实我不明白的是，-ing分词短语和-ed分词短语在句尾，前加逗号和不加逗号在修饰对象的问题上有什么区别。书上也没有讲，请教NN！！
