According to the passage ,considerable in the trade union movement grow from the outdated and ineffcient structure of the trade unions strains and tensions. 麻烦英语高手分析一下此句的句型结构.谢谢
我认为这是一个倒装句式
According to the passage 句前状语
strains and tensions 主语
grow from 谓语
the outdated and ineffcient structure of the trade unions 宾语
considerable in the trade union movement 修饰主语的定语
不知道这样理解对不对 请英语高手们指教
参考句子如下：There are considerable strains and tensions in the trade union movement ,someof them arising from their outdated and ineffcient structure.
