好吧。我知道斑斑忙。。但还是把问题贴出来。。。 在08prep 190中对独立主格的讲述有例句：Visitors to the park have often looked into the leafy canopy and seen monkeys sleeping on the branches, with arms and legs hanging like socks on a clothesline.这里的with做独立主格吗？ 斑斑在http://forum.chasedream.com/GMAT_SC/thread-536900-1-1.html中说： 1. 表示原因，此时不需要考虑逻辑主语，只是修饰前面整句 2. 表示伴随动作(非伴随结果)，此时需要注意逻辑主语，且前面不能是完成时态(这样就不能伴随动作了).（with短语要表示伴随结果则需要用with the result of，如prep2-193）. 3. 表示状态（此时前面需要是主系表），同样需要逻辑主语。 排除1，不用说了。 也许排除2，因为190前是完成时。 也许排除3，前面有主系表吗？难道monkey sleeping能算做主系表？
可是我又发现。。。og10对此句的解释：Choice D, the best answer, not only forms a correct and clear sentence by supplying the present perfect verb have ... seen, but also solves the problem of the whose ... clause by using the appropriately placed adverbial phrase with arms and legs hanging... to modify sleeping。。。
btw。关于独立主格逻辑主语问题。 独主的逻辑主语是否就是指独立主格部分的名词或者代词呢？ 我不能明白为什么with表原因时候不需要逻辑主语？ 08prep175中With the cost of wireless service（不是逻辑主语？） plummeting in the last year and mobile phones becoming increasingly common。版主给的两个例子：With John away there's more room in the house。I can't do my homework with all this noise going on. 版主的意思是不是，在with表原因时，由于with中类似逻辑主语的东西（比如the cost）不和句子主语发生关系，所以，在以上三个例子中，粗体字都不能算逻辑主语？那么，the cost等词算什么呢。。。。
PREP2008.190. (GWD-28-Q24) 中给出的例句是否正确？ Visitors to the park have often looked into the leafy canopy and seen monkeys sleeping on the branches, with arms and legs hanging like socks on a clothesline. 独立主格的逻辑主语应该是主句主语，该句中的独立主格部分明显是修饰monkeys的。
