麻烦问下英语句子结构
请问这句:we need these mutually agreed-upon social rights and wrongs because without some structure we'd be a bunch of headless chickens running around unable to function as a group.请问running around unable to function as a group这个部分作什么成分,属于什么结构.

修饰前面WE的非谓语从句(主语从句),不能成为“无头鸡”的定语从句原因是缺连接词与系动词BE.英语语法中存在着前面主语明确但是后面又前后主谓一致时后可省去主谓,而RUN与WE是主动关系,所以.
