【研学•析】Ⅰ. 过去分词(短语)作状语
1. 定义: 过去分词(短语)作状语, 表示动作发生的背景或情况, 其逻辑主语都是句子的主语。2. 功能: 过去分词(短语)在句中作状语可以表示时间、条件、方式或伴随、让步、原因等。(1)作时间状语时, 可转化为when, while或after等引导的状语从句。(2)作条件状语时, 可转化为if, nce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althugh, thugh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: lst(迷失的), seated(就座的), hidden(隐藏的), lst/absrbed(沉浸于), dressed in(穿着), tired f(厌烦)等。
Ⅱ. 过去分词/现在分词作状语的区别
【点拨迷津】过去分词与现在分词的完成被动式(having been dne)作状语时, 都具有被动意义, 有时可以互换, 但是having been dne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 d it well. 2. ________ (laugh) at by many peple, he cntinued his study. 3. (2019·天津高考) Hwever, technlgy is als the applicatin f scientific knwledge t slve a prblem, ________ (tuch) lives in cuntless ways. 4. ________(realise) that he made a mistake, he made an aplgy t us. 5. (2019·北京高考)Earth Day, _______ (mark) n 22 April, is an annual event aiming t raise public awareness abut envirnmental prtectin. 6. Mrs Wu came in, ________ (fllw) by her daughter.
题组二: 句型转换(分词形式变为状语从句)①Having been shwn arund the library, we came t the classrm building. ___________________________________, we came t the classrm building.  ②Mved by the stry, he decided t study harder. ______________________________, he decided t study harder.  ③United, we stand; divided, we fall. ______________united, we stand; _____________divided, we fall.  
After we were shwn arund the library
Because he was mved by the stry
If/When we are
if/when we are
④Once visited, the city will never be frgtten. _______________, the city will never be frgtten.  ⑤Althugh having been published many times, the bk still sells well in the market. ___________________________many times, the bk still sells well in the market.  
Once it is visited
Althugh 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 dne表先后, 千万牢记在心中。

5. 【解析】guided。考查非谓语动词。由后面的by可知, 用过去分词形式表示被动, 故填guided。6. 【解析】adjusted。考查非谓语动词。此处have sth. dne 是固定结构, 表示“使某事被做”, 故填adjusted。7. 【解析】United。考查非谓语动词。本句中unite与其逻辑主语he之间是动宾关系, 表示“他被建议和其他有相同志趣的人联合起来”, 故填United。8. 【解析】wh/that。考查定语从句的引导词。本句中先行词是peple, 表示人, 关系代词可以用wh/that, 故填wh/that。
