●案例探究
1.Everyone________ their seats,the meeting began.
A.taken B.taking
C.having taken D.to take
命题意图：此题考查独立主格结构作时间状语。此题属五星级题目。
知识依托：名词或代词+现在分词作状语，名词或代词就是分词的逻辑主语。
错解分析：A项taken为过去分词，它与逻辑主语之间逻辑上是被动关系，而此题中everyone与take their seats 应为主动关系。B项强调动作与句子谓语表示的动作同时发生，而此题中应是先就座，后开会，有明显的先后顺序。
解题方法与技巧：①everyone与take their seats是主动关系。
②分词与句子谓语有明显先后顺序。分词应用过完成式。
答案：C
2.He stood there,his hands________ behind.
A.tying B.tied
C.were tying D.were tied
命题意图：此题旨在考查独立主格作方式状语。此题属四星级题目。
知识依托：“名词或代词+过去分词”作为独立主格结构作状语。名词/代词与过去分词构成逻辑上的被动关系。
错解分析：D项干扰性最强，但是若选D项，题干为两个独立的简单句，缺少连词，可把句子改为He stood there and his hands were tied behind.
解题方法与技巧：弄清楚名词与分词之间的逻辑关系。
答案：B
3.________,Mother had to stay at home and looked after him.
A.Being ill B.He was ill
C.Tom being ill D.To be ill
命题意图：此题考查独立主格结构作原因状语。此题属五星级题。
知识依托：名词或代词加现在分词构成的独立主格结构。
错解分析：干扰性最强的选项为A项，A项为现在分词短语作状语，其逻辑主语应是句子的主语Mother,那和“Mother had to…looked after him”意思不一致了。
解题方法与技巧：掌握分词作状语与独立主格结构作状语的区别。
答案：C
●锦囊妙计
1.独立主格结构是由一名词或代词（作逻辑主语）加现在分词、过去分词、不定式、形容词、副词或介词短语构成，用作状语。
2.名词与现在分词是逻辑上的主动关系，与过去分词是逻辑上的被动关系。
3.掌握分词或分词短语作状语与独立主格结构作状语的区别。
