关于AB中amounting做伴随
我一直以来，对伴随的理解（逗号+Ving），要么修饰的是主句的主语，也就是主句主语是这个动词ing的逻辑主语，要么这个动词ing修饰的是前面的整个主句。昨天做到这个题目，我上曼哈顿查了一下，有人跟我有一样的想法，发现Ron对这个解释是：it‘s not either/or， it’s both。When you have one of these modifiers, the modifier should modify the action of the preceding clause AND should be pertinent in some way to the subject of that clause.
我想知道，这是什么意思，为什么动词ing同时修饰前面的句子，还跟主语相关。在我的理解里，修饰主语，和修饰整个句子，应该是两件事，为什么同时满足呢？
另外，怎么判断，这个动词ing是修饰前面的整个句子，还是主语呢？
这是个挺好的问题。但首先，一定要搞清楚伴随状语的由来。
相信你看完伴随状语的由来，就能理解为什么又是主语又是修饰动作了。因为原本状语从句就是修饰动作的，所以伴随状语自然就是修饰动作的。又因为伴随状语是一个主语和它的主句主语相同的一个状语从句的简化，所以自然doing的逻辑主语就是主句的主语了。
因此，这两个概念不矛盾，因为它们本身就是伴随状语的两个特点。
