难句理解与剖析

For a start, appraising isn't something many managers do naturally, oftheir own accord.

请问of their....在整句中做什么成分，能否讲解的详尽些！谢谢！

For a start,appraising isn't something many managers do naturally, of their ownaccord.

of their ownaccord 是介词短语，作方法状语，修饰动词 do，与前面 naturally并列。

of 与 out of 同义，表示出于某种方法或目的。所以，of one's own accord 意为 “出于自愿” 或 “主动地”。假如不想细究，也可按习语记住，理解。
