23题我选的是D，能否解释一下为什么选A而不选D

23: The primary purpose of the passage is to

D A

A.          present an interpretation of the chronological relationship between bipedal locomotion and certain other key aspects of human evolution

B.           compare the evolutionary advantages and disadvantages of bipedal locomotion to those of quadrupedal locomotion

C.          argue that the transition to a nuclear family structure was a more crucial step in human evolution than was the development of stone tools

D.          analyze anatomical evidence of bipedal locomotion to show that the large brain of modern humans developed at a later stage of evolution than was previously believed

E.           use examples of muscle and bone structure to illustrate the evolutionary differences between modern humans, australopithecines, and chimpanzees

自己看明白了，很狡猾，文章只说了直立和大脑发育的相对先后次序，并没有说具体的时间

做阅读的时候，要小心选项，这题就是ETS的典型出题套路
下次可不能中了老美的招

不对啊，原文的第一句如下：
Anthropologists once thought that
the ancestors of modern humans began to walk upright because it freed their
hands to use stone tools, which they had begun to make as the species evolved a
brain of increased size and mental capacity.
这句不就是previously believed的吗？感觉楼主这样解释D选项的错误不对啊。

同意楼上的，这个解释不是太对。
我也选错了。不是很懂。求解？
是因为文章的第一段又在说tools使用和直立行走的时间关系。还有最后一段，重点在讲进化成nuclear family等等都是key aspects of human evolution
而不仅仅是在说脑子进化和直立行走之间的时间关系证明。

同意楼上的说法。这题我也不小心选错了D。
这是一道主旨题，主旨题正确选项必须出现文章的中心词。本文的中心词就是bipedal locomotion 直立行走；而D的中心词是brain develop，所以不对。上当了。

Q22选C的筒子看看这句话 Lucy’s wide, shallow pelvis is actually better
suited to bipedal walking than is the rounder, bowl-like pelvis of the modern
human, which (?) evolved to form the larger birth canal needed to accommodate
the head of a large-brained human infant. 说明Lucy的pelvis是和人类的是不同的，但是他们都可以直立行走。

juvenren

pelvis没有说不同，只是说了更适应什么方式的行走。而前一句话的Reconstruction of the pelvis相似，既然pelvis的构造相似，这和答案的shape of pelvis是很好的替换。所以我认为选C

juvenren

楼上这句“这是一道主旨题，主旨题正确选项必须出现文章的中心词”概括的非常好，受教了，谢谢！

Reconstruction of thepelvis (hipbones) and femur (thighbone) of “Lucy”, a three-million-year-oldskeleton that is the most complete fossilized skeleton from theaustralopithecine era, has shown that they are much more like the correspondingbones of the modern human than like those of the most closely related livingprimate, the quadrupedal chimpanzee.
咋不看这句呢？！~难道是因为比较对象不同：当pelvis 和 the quadrupedal chimpanzee的pelvis比就更像现代人类的构造，但是单独和人类比还是有区别？！~~我是这么理解的。。。

23题我也选的D，因为第一段出现了once thought这一关键词，让人产生新老观点对比的思路。
后来仔细想想，D的问题出在 large brain of modern humans developed at a later stage of evolution than was previously believed，这句话主要强调大脑发育的时间比老观点预测的要晚。但文章是比较直立行走和大脑发育的时间先后。
同时，anatomical evidence是局部信息。文中只有在第二段的fossil部分提到骨头的结构，第一段和第三段则是通过其他研究的证据来判断 直立行走，大脑发育以及使用工具等的先后顺序。
所以，从主旨题的角度来说，还是选A比较好~

第一次做选了D。第二次选的C。Reconstruction of thepelvis (hipbones) and femur (thighbone) of “Lucy”, a three-million-year-oldskeleton that is the most complete fossilized skeleton from theaustralopithecine era, has shown that they are much more like the correspondingbones of the modern human than like those of the most closely related livingprimate, the quadrupedal chimpanzee.这句说的是lucy的骨头比起同时期的原始人更像现代人的吧，所以不能说她更像现代人？？？？
不过还是不明白D哪里看出来的。

同样不明白22题的飘过。
D在原文都没找到出处
