being accompanied by a police,he walked to the phone.和accompanied by a police,he walked to the phone.的区别?

问题描述:

being accompanied by a police,he walked to the phone.和
accompanied by a police,he walked to the phone.的区别?

前提:如果一定认为第一句在语法上是正确的话
being accompanied by a policeman,he walked to the phone.------表明:两个人一起走到the phone面前。
accompanied by a police,he walked to the phone.-------- 表明:打电话时,the policeman没有跟到the phone面前。

Being 表示“正在”由一位警察陪同,时态不同.
