是的,as troubled 中的 troubled 是过去分词。as 加过去分词,中间省略的不是is,而是 being。as troubled一起不是做状语修饰described,这里的 as 是引导一个宾补。
Rojas' testimony struck a different tone than some of the earlier witnesses, who described the company as troubled from the top down and focused more on profit than science or safety.
这句话的as troubled的这个troubled 是过去分词吧,as 加过去分词这个中间是不是有省略is ?as troubled一起做状语修饰described吗?
