作状语的目前分词完成式可否改为过去分词（动词为及物动词）

Having been shown around the lab,we were led into a big hall.
可否改为
Shown around the lab,we were led into a big hall.

条件或时间状语一般直接用过去分词，但假如强调分词的“被动动作”发生在谓语动词的动作之前，也可以用having been done。比如：

Given more time, I’ll do it better. 假如多给点时间，我会做得更好。

Having been revised several times, my composition was rated as an excellent one. 经过几次修改，我的作文被评为出色。

Having finished the work, they went home. 可以改为独立主格结构The work finished, they went home.
