Since/Asshewasgivenadvicebythefamousdetective,theyoungladywasnolongerafraid.

(give)advicebythefamousdetective,theyoungladywasnolongerafraid.Becauseitwasdoneinahurry,hishomeworkwasfullofmistakes.Given一般以because,as,since等词来引导。

(shut)thedoorbehindhim.shutting过去分词作状语时，过去分词所表示的动作与句子主语之间构成逻辑上的动宾关系。

(give)

moreencouragement,theboycouldhavebehavedbetter.Given（2）时间概念过去分词所表示的动作发生在谓语动作之前,或表示“一种状态”。Absorbedinherwork,shedidn’trealizeIwasbehindher.Dressedinawhiteuniform,helookslikeacook.现在分词表示的动作与谓语动作同时发生或在说话时正在进行。Istoodthere,waitingforher.

areeasilyforgotten.

When

askedwhyshecamehere,thegirl

keptsilent.2.过去分词作状语时，其逻辑主语必须与句子的主语保持一致(现在分词作状语同样如此)，否则需加上自己的逻辑主语，构成独立主格结构。Scoldedbyhisteacher,hefeltverydepressed.Hissonscoldedbyhisteacher,hefeltverydepressed.3.有些过去分词(短语)来源于系表结构，作状语时不表示被动而重在描述主语的状态。这样的过去分词及短语常见的有:lost(迷失的),seated(坐),hidden(隐藏的),lost/absorbedin(沉浸于),dressedin(穿着)等。
