态，这样的过去分词及短语常见的有：

be lost / absorbed

in, be dressed in, be tired of, be worried about, be based on, be located in等

【观察5】

现在分词（v-ing）过去分词（done）与现在分词完成被动式(having been done)选用



Seeing nobody at home, I had to leave. 

Not knowing what to do, he went to his parents for help. 

Written in a hurry, this article was not so good.



Deeply moved by the movie, the children began to cry. 

Having been discussed several times, the decision was finally made.



Having been shown around the library, we were shown around the lab. 【归纳5】

选用分词做状语时，首先要弄清分词与 之间的关系，若二者构成主谓关系，则用 做状语，表示主动；若二者构成动宾关系，则用 做状语，表示被动。过去分词做状语侧重的是动作完成，现在分词完成被动式（having been done）侧重的是时间先后。
