the quadrupedal chimpanzee. Lucy’s wide, shallow pelvis is actually

better suited to bipedal walking than is the rounder, bowl-like pelvis

of the modern human,

23选什么？

同意斑竹的看法。

23题选A，因为文章的中心内容就是在讨论直立行走的问题。

20题，我选D。


C觉得有点问题。

哪位再详细参详一下。

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

又看了一遍,A绝对错了，没有提到直立行走和别的certain other key aspects of human evolution 关系，而是讨论了到底什么导致了直立行走，一直都在直立行走内部作讨论。

答案应该是A

23。文章没有强调几个key aspects的时间顺序。主要还是在讲为什么要直立行走的原因。

C B D D

20: "development
of a nuclear family structure" in conjuction of "
        transition from walking on
all fours to walking upright" because they need to "use
of the hands to gather and carry food". During the process, they "modification
of propulsive muscles to provide stability and control in locomotion".
C is the latest

21: "Lucy’s
wide, shallow pelvis is actually better suited to bipedal walking than is the
rounder, bowl-like pelvis of the modern human"
B:  less well adapted to walking
upright

22. Very clear
D: "method
of locomotion"    

23. The passage doesn't aim to investigate "the chronological relationship between bipedal
locomotion and certain other key aspects of human evolution". The first paragraph says ppl thought blah blah, however, ... "discoveries
of the three-million-year-old fossilized remains of our hominid ancestor
Australopithecus have yielded substantial anatomical evidence that upright
walking appeared prior to the dramatic enlargement of the brain and the
development of stone tools."
The following two paragraghs explained why in details.
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"
my 1c.

23支持A

文章提到的“a brain of increased size”和“dramastic enlargement of the brain”不等于D中的“the large brain of modern humans” （好像hominid的脑和现代人的脑还差一些）
