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

为什么不选C？

Og:In C, the phrase having been assigned... is uncertain in reference, making the sentence unclear。

看到以前的分析说，现在分词和不是that引导的定语从句都是非限定的性质，那么B、C怎么区分呢？

C中的having been assigned的修饰对象不明.而who做关系代词引导限制性定语从句.

MM说的现在分词和不是that引导的定语从句都是非限定的性质 我不太明白！但此处用限制性定语。而非限制定语从句的which不能指前面的整个句子，正确的表达是：

句子，-ing （-ing分词短语代替which从句，做伴随结果状语）

句子+N.， which。。。（which引导从句修饰N.）

补充以下,having been...这种结构作为形容词永远错

谢谢两位NN

想再问一下，

我说的 现在分词和不是that引导的定语从句都是非限定的性质 是指

对于限定性定语（that从句以及with短语等等）和现在分词作定语（非限定定语）的区别就是一个局部和整体的关系，限定定语指的只是修饰词中的一部分东西

就本题来讲，用who作为限定定语，指部分派到UN的官员。。。若用分词修饰指所有派到UN的官员。。。

这样的理解对吗？

有没有NN可以给个指点？谢啦
