with独立主格的问题

FGHYU19912301

今天看prep08上写的一句话：1.   with独立主格结构：

由“with    ＋宾语＋宾补”构成的复合结构，在句中可作状语，表示伴随。这一结构中的宾语补足语可由现在分词、过去分词、形容词、副词或介词短语等来充当：
Visitors to the park have often looked into theleafy canopy and seen monkeys sleeping on the branches, with arms and legshanging like socks on a clothesline.

这个例句是正确的吗？with独立主格不应该是修饰主句visitors的吗？但是逻辑上修饰的是monkeys阿

另外prep08-220
The results of thecompany's cost-cutting measures are evident in its profits, which increasedfive percent during the first three months of this year after it fell overthe last two years.  
A.    which increased five percent during the first threemonths of this year after it fell

B.     which had increased five percent during the firstthree months of this year after it had fallen
C.    which have increased five percent during the firstthree months of this year after falling
D.     with a five percentincrease during the first three months of this year after falling   (C)
E.  with a five percent increase during the firstthree months of this year after having fallen选C,对这个没什么疑问，
DE的解释说with独立主格修饰前面的分句，而不是its profits，修饰错误。但是这个with修饰哪里错了呢？伴随results阿 这个5 percent就是伴随了results are evident 呀

第一个问题：
with独立主格是做伴随状语修饰的monkey的sleeping这个动作，表示的是和sleeping同时进行的一个状态

prep2008-220的问题：

  由于with独立主格前面是主谓宾结构，因此，with结构是伴随前面的这个SVO，但是题目的原本意思，是想用with结构修饰it profits，因为只有profits才能increase和falling，所以说DE都不对，因为使用的是with结构。

好的，谢谢，是不是如果with 表示伴随事情，或修饰SVO的时候就没有逻辑主语了？
