题目

In the struggle,the strap broke and,with the bag in their possession,both men started running
through the trees.其中with是什么意思,启什么作用,我觉得没有with也说的通,意思也能啊,求详解

答案

非谓语中独立主格结构
with the bag in their possession,with+名词+介词短语
什么是独立主格结构,简单说是状语从句的变形
上述句子,原来是这样的：
when both men started running,the bag was in their possession
状语从句的主句的主语是men,从句的主语是bag,两个主语不一样,这是前提
然后,去掉连词,并且不能使从句成为句子,就叫独立主格
方法：with+n+adj
with+n+分词
with+n+adv
with+n+介词短语,with可以省略
时间关系,就不一一举例了,
