标志结构四：状语从句省略形式，主语一致

　　错误句式1：After seeing the movie, the book was read by him.

　　改为：After seeing the movie, he read the book.

　　错误句式2: Although located in the center of the city, people have dismantled the building.

　　改为：Although located in the center of the city, the building has been dismantled by people.

　　由以上两个例句我们可以看出，当句中包含状语从句省略形式时，如

　　After/Although/When –ing, SVO.

　　After/Although/When –ed, SVO.

　　则需要保持此处–ing/–ed 的逻辑主语与主句主语保持一致。

　　例如2017 年5 月北美真题第32 题

　　After hearing a lineup of famous art critics testify to the aesthetic value and originality of nonrepresentational art like Bird in Space, the court's ruling was in favor of Brancusi.

　　A. NO CHANGE

　　B. the ruling of the court was in favor of Brancusi.

　　C. the court ruled in favor of Brancusi.

　　D. Brancusi was the favorable receiver of the court's ruling.

　　做题思路：

　　1. 识别考点：看到句首状语短语中的连词after+hearing，明确考点。

　　2. 句子主语应该是hearing 这个动作的执行者，C 选项的句子主语the court 符合主语一致的原则，所以正确。

　　标志结构五：形容词的省略结构，主语一致

　　错误句式：Large and hexagonal, I find the pills are really effective.

　　因Large and hexagonal 的主语应该是pills，而不是I，故以上句子有误。

　　应改为：Large and hexagonal, the pills are really effective for me.

　　例如Khan 语法‘A “Rosie”Turn on American Labor ’第3 题

　　The propaganda posters featured images of a coverall-clad, muscular woman named Rosie the Riveter. Dirty yet wearing makeup, brawny yet feminine, female factory workers were symbolized by Rosie.

　　A. NO CHANGE

　　B. Rosie became a symbol of the American female factory worker.

　　C. a symbol of the American female factory worker was developed in Rosie.

　　D. American factories began using Rosie to symbolize their female workers.

　　做题思路：

　　1. 识别考点：句首有状语Dirty yet wearing makeup, brawny yet feminine

　　2. 句子主语应与这个状语的逻辑主语Rosie 一致，B 选项的主语符合，所以选B。

　　考点识别意识对于文法部分而言很重要，对于本文讲到的逻辑主语一致性考点的相关考题尤其重要。这是一种技巧性比较强的题型，一旦通过这五种标志性结构识别了考点， 做题就会又快又准。
