从本文中可以推断出什么？

CWalkingontwolimbsandwalkingonfourlimbseachhavetheiradvantages.DHumanwalkingontwolegsdevelopedasameansofsurvival.

答案与题解：

1.A第一段第一句和第二句说明，大多数人对人类直立行走习以为常，并不质疑这种习惯。而A的内容正好与此相反，所以是答案。其他选项所述内容均可从第一段和第二段推断出来.

2.B文章报道，科学家通过实验证实黑猩猩直立行走是为了解放前肢，让前肢搬运对其生命至关重要的资源，从而推断出人类祖先也经历了从四足到二足的进化过程。科学家想通过对黑猩猩的实验解释人类直立行走的成因。所以B是答案，A、C、D选项不是科学家进行研究的目的。

3.C第五段明白无误地描述了黑猩猩全然不顾油棕榈坚果(ignoredtheoilpalmnutsaltogether)，集中精力抢运可乐果。所以C是答案，B、C、D的内容不符合文章原意。

4.D黑猩猩用后肢直立行走，搬运资源的效率提高了四倍。选项D符合原意，是答案。选项A、B、C的内容文章中没有提到，所以不是答案。

5.D了解了通篇文章的意思，就会选择选项D，人类直立行走是受生态环境所迫，是人类生存的一种手段.直立行走是自然选择的结果。选项A和C的内容文章中没有涉及.文章中有选项B的内容，但它不是文章的主旨。
