求帮分析一下这句话语法

It is vividly depicted in the cartoon that a boy is running along the racetrack with painful efforts, sweat pouring down his face.
efforts后面加逗号以及sweat后面动词用ing该怎么理解？谢谢

Answer 1

, sweat pouring down his face.

这是个独立主格结构的掘棚正分词短语用作状语。

一般情况下，分词短语作状语时，其逻辑主语就是句子的判悔主语。

本句的主语是a boy 。(a boy) pouring down his face.显然不合逻辑。在这种情况下，分词短语可以带有自己的逻辑主语。

sweat 就是这个分词和虚短语的逻辑主语。
