3、hile或after等引导的状语从句。(2)作条件状语时,可转化为if,once或unless等引导的状语从句。(3)作原因状语时,可转化为as,since或because等引导的状语从句。(4)作让步状语时,可转化为although,though或even if等引导的状语从句。(5)作方式状语时,如有连词as if就可转化为as if引导的方式状语从句,若无连词,则可转化为并列结构。(6)作伴随状语时,一般可转化为并列结构。【点拨迷津】(1)过去分词作状语时,有时为了强调,前面可带有连词,如when,while,if,as if,unless,until等,以使句意表达得更清楚。(2)过去

4、分词作状语时,其逻辑主语必须与句子的主语保持一致,否则需加上自己的主语,构成独立主格结构。(3)有些过去分词(短语)来源于系表结构,作状语时不强调被动而重在描述主语的状态。这样的过去分词和短语常见的有:lost(迷失的),seated(就座的),hidden(隐藏的),lost/absorbed(沉浸于),dressed in(穿着),tired of(厌烦)等。.过去分词/现在分词作状语的区别逻辑关系时间概念过去分词作状语所表示动作与句子的主语之间是逻辑上的动宾关系,即表被动所表示动作往往发生于谓语动词所表示动作之前,或表示“一种状态”,与谓语动词所表示的动作同时发生现在分词作状语所表示动作

5、与句子的主语之间是逻辑上的主谓关系,即表主动现在分词的一般式(doing)表示的动作与谓语动作同时发生或几乎同时发生;现在分词的完成式(having done)表示动作发生在谓语动作之前【点拨迷津】过去分词与现在分词的完成被动式(having been done)作状语时,都具有被动意义,有时可以互换,但是having been done结构强调动作先于句子的谓语动作。【内化用】题组一:用所给词汇的正确形式填空1._(give)health,I can do it well.2._(laugh)at by many people,he continued his study.3.(2019天津

9、 well in the market._many times,the book still sells well in the market.Once it is visitedAlthough it has been published【常温故勤总结】分词作状语,主语是问题。逗号前后两动作,共用一主语。主语找出后,再来判关系。现在分词表主动,过去分词表被动。having done表先后,千万牢记在心中。.用括号内词的适当形式填空1.When I came in,I saw him _(sit)in the sofa and doing nothing.2.Although _(warn)o
