如何理解这里的up用法

his eyes fell on a small crab that stood before him with its claws up as if it were listening to what he said.

这里的its claws是名词，后面的up怎么理解？

His eyes fell on a small crab that stood before him with its claws up as if it were listening to what he said.

with its claws up：

1. 名称：叫做“with 复合结构”。

2. 构成：with + 宾语 + up （副词作宾补）

2. 作用：作方式状语，修饰定语从句的谓语动词 stood，说明“站立的方式”。它不可能隔着谓语动词去修饰 crab，不是定语。

又如：

The proud girl walked away with her head up. （方式状语）

with的符合结构做定语修饰crab.也可以做状语。

如：

He stood with his head high up.（状语）

他昂首挺立。

原文：看到一个蟹螯高举的螃蟹横在他面前。
