请个高手来看个句子
（In addition to ）conducting surveys from various customers,Michael also works as an independent arbitrator.
书上说conducting surveys from various customers是动名词短语,所以前面应该用介词.
如果这样理解：Michael conducts surveys from various customers,Michael also works as an independent arbitrator.
可以把前句变成分词结构 conducting surveys .
那么原句到底是分词结构还是动名词短语呢?二者又有何区别呢?

Answer 1

支持动名词短语说法, 如果理解为分词结构的话,则一是不能用（In addition to ）,二是conducting和works 2个动作要有一定的逻辑关系
