详细解析GMAT阅读四类插入语

 在GMAT阅读中，GMAT阅读插入语的复杂修饰以及插入语的混合使用往往造成GMAT阅读障碍。而且一般遇到这类GMAT阅读插入语的句子，思路很容易被打断，造成理解上的偏差，针对这一问题，南京朗阁特将四类常见GMAT阅读插入语整理如下：
 
　　1、as引导的短语或句子作GMAT阅读插入语
　　例句：The factors favoring unionization drives seem to have been either the presence of large numbers of workers, as in New York City, to make it worth the effort, or the concentration of small numbers in one or two locations, such as a hospital, to make it relatively easy.
　　朗阁解析：这个句子中出现的两处插入语都表示举例，插入语后面接不定式表目的。本句中的as后接的是介词短语，插入语比较短，有时候as 会引导一个句子，用来分散考生注意力。我们先把两处插入语省略掉，句子变成The factors favoring unionization drives seem to have been either the presence of large numbers of workers to make it worth the effort, or the concentration of small numbers in one or two locations to make it relatively easy.这样以来，either or 表示的并列结构就很清晰了。
 
　　2、介词短语作GMAT阅读插入语
　　例句：Now Congress, in apparent agreement, has required by law that businesses awarded federal contracts of more than 0,000 do their best to find minority subcontractors and record their efforts to do so on forms filed with the government.
　　朗阁解析：本句的GMAT阅读插入语出现在主语之后，把主语和谓语分隔开来，这种插入语其实也可以和其他成分连接在一起，用插入语的形式表现出来反而分明一些。虽然插入语会使得考生思路被打断，分散注意力，但在这种情况下它能成为一种信号，告诉考生这里可以暂时不读，对句子结构的理解不造成任何影响。本句的难点在于过去分词作定语，例如business awarded federal contracts和forms filed with the government. (责任编辑：admin)
