1.该题是考查独立逐个结构的,该结构的构成是：“逻辑主语 + 分词短语”,其句法作用是方式状语：即：作为由...指定就职于...的第一个女性,....
The first woman appointed by a United States President to a cabinet position,Frances Perkins held the post of labor secretary for twelve years.
2）句中：
Frances Perkins,the first woman appointed by a United States President to a cabinet position,held the post of labor secretary for twelve years.
A) The first woman appointed by a United States President to a cabinet position was
逻辑主语 + appointed by ...+ was ,很明显was是个多余的动词.
(B) The first woman appointed by a United States President to a cabinet position
逻辑主语 + appointed by ...,符合这个结构.
(C) Appointed by a United States President to a cabinet position was the first woman who
动词 Appointed 没有依附关系,是谁实施了这个行为,这是其一；其二,who 作为关系代词只能置于从句之首,而不能拖后；其三,只有把句子改变成正the first woman who was appointed by ...才可以用作同位语,但不可以放在句首作状语.
(D) The first woman was appointed by a United States President to a cabinet position who
作为一个独立的句子,who 也是多余的东西；即使去掉who使其成立,但是和上面的主句构不成语义上的关系,前面说“Frances Perkins干秘书工作多年”与这里的“第一个女性被...指定到一个内阁的职位” 互相间没有任何语法关系.
2.本题考查定语从句.
首先把定语从句that distinguish human beings from mother primates 从整个句子中拆分出来即成为下列的主句：
复数主语 + are related to the ability of people to stand upright and walk on two legs.
(A) Many of the physical characteristics
many of ...是复数
(B) Of the many physical characteristics：
of the...应该是缺省了一个不言自明的复数名词,但是上下文中没有给出这个名词
(C) The physical characteristics
尽管是复数名词但是指的是所有的身体特征,不符合逻辑,
(D) There are many physical characteristics
如果用句子作主语,引导主语从句的连词that是不可省略的,即使可以,也不能说“存在许多身体特征这件事与...有关”,同样不符合逻辑.

1.答案是B.The first woman appointed by a United States President to a cabinet position 和Frances Perkins
是同位关系。
2.答案是B.that distinguish human beings from mother primates 是定语从句，修饰前面的Many of the physical characteristics ，are related 是谓语动词。

第一题的句子是插哪里的?好象位置不对吧?
第二题的话
正确的句子是
Many of the physical characteristics [that disginguish human beings from mother primates] are related to the ability of people to stand upright and walk o...

第一题的句子是插哪里的?好象位置不对吧?
第二题的话
正确的句子是
Many of the physical characteristics [that disginguish human beings from mother primates] are related to the ability of people to stand upright and walk on two legs
中括号里的是定语从句,解释是什么样的特征,are related这个里面的are是这个句子的真正谓语
如果选D的话There are..已经有are这个谓语了,这个就是为什么在There be结构里后面动词要用过去或者现在分词形式,一个句子只能有一个谓语
