Question

with做什么成分？

在China is about5000years ol, with many people中

Answer 1

with是一个 “in + 抽象名词 + with” 结构，用来表示“主语和 with 后的宾语之间，处于一种什么关系或状态中”。
1. 从结构看，是复合介词，不宜拆分。
2. 从语法作用看，介词短语可以作状语，也可以用作表语，本句便是。
3. 从表意看，这类结构主要表示“当事人双方之间的关系”，例如：“一致、协作、和睦、竞争、分歧、麻烦、纠葛” 等意义。
1. She asked him if he had ever been in trouble with the police.
2. This story has to do with her life.
常见的有：
in trouble with 与...有麻烦/纠葛/纠纷
in conjunction with 与...配合、协作
in contrast with 与...相对比
in harmony with 与…和谐；与…一致
in keeping with与…一致

Answer 2
