求教一道阅读题 （ 阅读36套 exe 6 第一篇）

Some modern anthropologists hold that biological  
evolution has shaped not only human morphology but  
also human behavior. The role those anthropologists  
Line ascribe to evolution is not of dictating the details of  
5  human behavior but one of imposing constraints—
. ----ways of feeling, thinking, and acting that ―come natu-
rally‖ in archetypal situations in any culture. Our   
―frailties‖ –emotions and motives such as rage, fear,
greed, gluttony, joy, lust, love—may be a very mixed  
10  assortment, but they share at least one immediate  
quality: we are, as we say, ―in the grip‖ of them. And  
thus they give us our sense of constraints.
  Unhappily, some of those frailties—our need for  
ever-increasing security among them—are presently  
15  maladaptive. Yet beneath the overlay of cultural  
detail, they, too, are said to be biological in direction,  
and therefore as natural to us as are our appendixes.
We would need to comprehend thoroughly their  
adaptive origins in order to understand how badly they  
20 guide us now. And we might then begin to resist their
pressure.  

2. It can be inferred that in his discussion of  
   maladaptive frailties the author assumes that
  (A) evolution does not favor the emergence of  
    adaptive characteristics over the emergence  
    of maladaptive ones
  (B) any structure or behavior not positively   
    adaptive is regarded as transitory in  
    evolutionary theory
  (C) maladaptive characteristics, once fixed,   
    make the emergence of other maladaptive  
    characteristics more likely
  (D) the designation of a characteristic as being   
    maladaptive must always remain highly  
    tentative
  (E) changes in the total human environment can   
    outpace evolutionary change

这是原题，可是为啥选e。。。题目有点看不懂啊，查过类似的解析，说什么abcd正常，而e不正常，表示不懂。。。

GRE已经考过了~ 记得这是一道老G原题 讲的挺抽象的，很有难度。 老G的原题网上应该是可以查到中文翻译的，对照中文翻译看一下应该就可以马上理解了

由 discussion of  maladaptive frailties 定位到 Unhappily 和 Yet 这两句
这两句说 frailties 现在是 maladaptive，但是这是不冲突的，自然的

由 presentely maladaptive 得知过去是 adaptive
基于某个 assumption 就可以解释这种现象，推出不冲突，自然的

e也就是说因为环境变化比人进化快，所以现在这些 frailties 已经不 adaptive

我的理解.首先,前面4个选项都说得太死. GRE中,说得非常肯定的东西往往都会有疑问,GRE本身就鼓励质疑,实证.那么这4个选项就都有问题
第5个选项,问题问得是infer,说明文章中并不明确点出,但通过逻辑和态度能判断出来. 文章最后一句: "and we might then begin to resist their pressure".是一种看似可能实则明确的态度, resist是个很强的词,说明作者对利用biology 改变culture持一种乐观和主动态度, 那么针对选项中"change the total human environment"作者也就是同样的一种主动的态度.那么e就可以是一个正确的答案.
选项a, doesn't favor -对应文中的"Unhappily",这个选项不全面
选项b, any太绝对
选项c, once fixed - 文中应该是可以改变的态度, 事物都是在变化的, 强调fix不合适
选项d, must always remain, 我感觉在gre中看到这样表述的可以直接排除了
所以,选e
