3 句子结构分析(happy前为什么没有is)

The background thread(后台线程) then goes to sleep, happy that it has freed some memory(内存) for running processes(运行的进程) and the OS(操作系统) to use.

请教各位专家,“happy that”从句是做什么句子成分呢?happy前的be动词为什么可以省略呢?

不能加 is,因为前面是一个完整的单句,后面是逗号,说明这是一句话。加了 is 后,变成一个主语,两个谓语动词用逗号连接:语法错误。happy that ...整个是形容词短语,作状语,原因状语。可以转换成一个状语从句。


我举一个相似的句子:
He couldn't sleep that night, excited that he had won the prize. =
He couldn't sleep that night, because he was excited that he had won the prize.
