1.(With one) of the most successful African American business in history,the MR Corporation was founded in 1959 in Detroit by Berry Gordy,Jr.
A.不改动；B.It was one; C.Being one; D.One; E.As one
但c和e为什么不行?答案说c和e与MR Corporation这个名词成分不平行,这里还要考虑平行吗?
2改句子：Although long considered a vestigial organ that has no function in humans,(the appendix,some scientists believe,may have) a significant role as part of the body's immune system.
正确答案是a,就是不改动
我选的是b：改成：the appendix,which,some scientists believe,may have
答案说b的话,句子就没动词,但which,some scientists believe,不是插入语吗?所以动词是may 反而a我觉得错是因为有2个动词啊：believe和may（就算some scientists believe是插入语,which指代appendix啊,然后动词是may have）

第一题遵循同位语优先原则,one代指the MR Corporation,所以是同位语,其他的选项都是赘余
第二题：some scientists believe可以看成宾语从句的主句,这句话也可以写成some scientists believe that the appendix may have ……,然后将some scientists believe 放在句中,省略that,这是一种是句式变得复杂多变的方法.此题遵循最简原则,b选项中的which多余了.SAT有很多题和这道题是同类的,以后要注意,把这个知识点记住就好

1. With one of the most successful African American business in history, the MR Corporation was founded in 1959 in Detroit by Berry Gordy, Jr.
1）原题中的 With one of ... 在句子中作状语，整个句子的意思是“带着历史上最成功的非美商行之一的业绩，MR 公司由 Berry Gordy, Jr 在底特律于1959年成立”
2）置换为 one 后，the MR Corporation 这个短语就成了它的的同位语，也就是说 one of ... ＝ the MR Corporation，二者属于平行关系。
3）Being one 是分词短语，用作原因、时间或方式状语，逻辑主语是 the MR，即“MR 公司由于是.../当MR公司是...的时候/MR公司以...的方式”，不管那种状语，显然都与主句的意思不符，属于不平行关系。
4. As one 中的 as 是介词，意思是“作为...之一”，MR公司...建立了。既然当年才建立，这时候这么会“作为历史上最成功的非美商行之一”呢？也属于不平行关系。
2. Although long considered a vestigial organ that has no function in humans, (the appendix, some scientists believe, may have) a significant role as part of the body's immune system.
一个句子正确与否，必须要综观整个句子，不能孤立地看问题，以下是两种选择的分析。
1）原句——
主体结构： the appendix may have a significant role as part of the body's immune system
插入语： some scientists believe
2.）改写后——
some scientists believe 是插入语没变。
主体结构就成了 the appendix, which may have a significant role as part of the body's immune system，其中的 which 无疑是指代 the appendix 的，那么 which may have a significant role as part of the body's immune system 就成了定语从句，但是 the appendix 则变成一个无依无靠的孤立词而游离于整句子之外，整个句子势必成了如下的结构：
——although 引导的让步从句 + 孤立词 the appendix + which 引导的定语从句
显而易见，改写后的句子有两个从句——让步从句和定语从句，但是唯独没有主句。
