  摘要:GMAT阅读文章中包含的信息量很大,许多时候考生无法迅速准确地找到自己需要的信息就会耽误解题速度。而阅读中比较常见的一种语法现象插入语其实能够给考生提供不少解题线索。本文将为大家解读GMAT阅读中的插入语。

  例句:How such large creatures, which weighed in some cases as much as a piloted

  hang-glider and had wingspans from 8 to 12 meters, solved the problems of

  powered flight, gre答案 and exactly what these creatures were-reptiles or birds are

  among the questions scientists have puzzled over.

  解析:非限制性定语从句与限制性定语从句的一个区别在于非限制性定语从句中和先行词之间只有比较松散的关系,出现在句中也是用逗号隔开,具有插入语的功能。我们先将插入部分略过不读,很容易发现这是一个疑问句。特殊疑问词为how

  much和what,从本句还能看出插入语的处理是非常灵活的,句中的reptiles or

  birds也可以看成插入成分。非限制性定语从句作插入语比较特殊的是弄清句子结构之后再回头看时,要与先行词紧密对应。但是这只限于非限制性定语从句出现在句中的情况下,如果出现在句尾,就不能当作插入语。

  例句:The factors favoring unionization drives seem to have been either the

  presence of large numbers of workers, as in New York City,bto make it worth the

  effort, or the concentration of small numbers in one or two locations, such as a

  hospital, bto make it relatively easy.

  factors favoring unionization drives seem to have been either the presence of

  large numbers of workers to make gre答案 it worth the effort, or the concentration of

  small numbers in one or two locations to make it relatively easy.这样一来,either or

  表示的并列结构就很清晰了。

  例句:Now Congress, in apparent agreement,has required by law that businesses

  awarded federal contracts of more than $500,000 do their best to find minority

  subcontractors and record their efforts to do so on forms filed with the

  government.

  解析:GMAT考试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更分明一些。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.

  例句:Increasingly, historians are blaming diseases imported from the Old World

  for the staggering disparity between the indigenous population of America in

  1492—new estimates of which soar as high as 100 million, or approximately

  one-sixth of the human race at that time—and the few million full-blooded Native

  Americans gre答案 alive at the end of the nineteenth century.

  解析:如果句中插入名词一般会视为同位语对待,但是同位语不会设置得如此复杂,而且起到进一步解释说明的作用,本句的插入语不同于一般用两个逗号隔开的情况,而是用两个小横线进行提示,作用相同。先把这部分复杂名词去掉,句子结构顿时豁然开朗,无非就是between…and的结构形式。这种情况下名词的出现也经常使用从句和多种修饰成分,所谓的“句子套句子”。这个句子中的插入语首先是or

  连接的并列结构,而两个结构又不是平行的,前半句使用从句,后半句用of的结构,实际上不过就是用这个复杂成分来表示一个大致的数字,这些GMAT考试介绍大家要注意。

  以上就是小编为各位考生整理的关于GMAT阅读重点之插入语介绍,希望考生积极做好备考工作,及时调整好状态,争取在GMAT阅读考试中取得理想的成绩!
