原标题：GMAT语法考试切不可搞混同位语和独立主格考点！
润饰语，毫无疑问是GMAT语法中被频频调查的点了，关于常考的从句和分词短语的润饰，大多数同学表明问题不大;而独立主格，许多同学表明心累，和同位语放在一同就愈加懵圈了，今日咱们就来说说这两大润饰成分的差异。
一、独立主格
界说：独立主格结构在句中作状语，多用于书面语。独立主格结构自身不是语句，在语句中作状语，表时刻、原因、成果、条件、随同、意图及状况等。一起是用逗号和主句离隔!
独立主格常见的7种方式：
1.名词/代词+介词短语
E.g.1 Every afternoon a very old woman hobbled past the ramshackle house, a vast load of firewood on her back.
2.名词/代词+形容词
E.g.1 The Trojans asleep,the Greek soldiers crept out of the hollow wooden horse.
3.名词/代词+过去分词
E.g.1 More time given,we should have done it much better.
4.名词/代词+现在分词
E.g.1 The temperature falling so rapidly,we couldn’t go on with the experiment
5.名词/代词+副词
E.g.1 This little excitement over,nothing was to be done but to return to a steadfast gaze at my mute companion.
6.名词/代词+不定式
E.g.1 We shall assemble at ten forty-five, the procession to start moving at precisely eleven.
7. with+名词/代词+不定式/分词/介词/形容词
E.g.1 With a revolver in his right hand, Johnny hurled his muscular body against the door.
给咱们留几道标题考虑一下，欢迎咱们在下方谈论留言，一起检测一下你是否真实理解了独立主格结构：
例题
解析：依据语句结构和主谓共同扫除A、D、E，其次，依据独立主格结构咱们决断挑选C 由于后边是独立主格结构，咱们上面有提到，要用逗号和主句离隔，而不是分号，一起也不存在平行联系。

二、同位语
界说：一个名词(或其它方式)对另一个名词或代词进行解说或弥补阐明，这个名词(或其它方式)便是同位语。
同位语与被它限制的词的格局要共同，并常常紧挨在一同。同位语除表明其同位成分的悉数含义外，还能够表明部分含义。
至于它在GMAT语法中的方位，能够放在句首、句中和句尾。
同位语出现在语句最初
eg: A great scientist, Edisonhad a great number of important inventions.
同位语出现在语句中心
eg: Edison，agreat scientist, had a great number of important inventions.
同位语出现在语句结束
eg: I like Thomas Edison, agreat scientist in the history of mankind.
以上都是咱们比较了解的方式，但是有一种同位语是GMAT语法中的难点，许多同学会和独立主格弄混的，咱们称作归纳性同位语，即：用一个归纳性的名词去归纳前面语句，或许前面语句中的短语或许名词，一般方式为名词或代词+that定语从句。
例题
Scientists have observed large concentrations of heavy-metal deposits in the upper twenty centimeters of BalticSea sediments, which are consistent with the growth of industrial activity there.
(A)Baltic Sea sediments, which are consistent with the growth of industrial activity there
(B)Baltic Sea sediments, where the growth of industrial activity is consistent with these findings
(C)Baltic Sea sediments, findings consistent with its growth of industrial activity
(D)sediments from the Baltic Sea, findings consistent with the growth of industrial activity in the area
(E)sediments from the Baltic Sea, consistent with the growth of industrial activity there
解析：这道标题中的findings便是做前面语句中large concentrations of heavy-metal deposits的同位语，C和D选什么应该就不难了吧。
