NO.6第一套Section4的短阅读：
Some modern anthropologists hold that biological evolution has shaped not only human morphology but also human behavior.The role those anthropologists ascribe to evolution is not of dictating the details of human behavior but one of imposing constraints—ways of feeling,thinking,and acting that "come naturally" 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 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 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 guide us now.And we might then begin to resist their pressure.
26.Which of the following most probably provides an appropriate analogy from human morphology for the "details" versus "constraints" distinction made in the passage in relation to human behavior?
A.The ability of most people to see all the colors of the visible spectrum as against most people's inability to name any but the primary colors
B.The ability of even the least fortunate people to show compassion as against people's inability to mask their feelings
C.The ability of some people to dive to great depths as against most people's inability to swim long distances
D.The psychological profile of those people who are able to delay gratification as against people's inability to control their lives completely
E.The greater lung capacity of mountain peoples that helps them live in oxygen-poor air as against people's inability to fly without special apparatus
我觉得选D,可是我怎么琢磨都觉得D很好.
首先,我将“detail”理解为具体问题具体分析,是“constraints”的一些突破和例外.
能够delay gratification的人应该是比较坚忍,但是日常生活中多数人都无法control their lives completely,因为太多时候我们被那些“emotions and motives such as rage,fear,greed,gluttony,lust,love……”constrain了,也就是“‘in the grip’of them”,从而不能为掌控命运而时时控制自己.多贴切.
可是E呢,在缺氧环境下生存和会飞没有太紧密的联系,具体来说,“不会飞”怎么能成为“在缺氧环境下生存”的一个“constraints”呢?这就好像说：“因为人不会飞,所以人会走也很稀奇.”怪,它怎么会成为正确答案?

请再仔细阅读一遍问题Which of the following most probably provides an appropriate analogy from human morphology for the "details" versus "constraints" distinction made in the passage in relation to human behavior?
请注意题目要我们做的类比是“human morphology ”而不是 “human emotions ”
“delay gratification” 以及你所说的“坚忍”是人的情感而不是人的形态.
答案E是合适的.生活在高山地区的人肺活量强能够在氧气不足的情况下生存,因此不需要特殊装置（如氧气包之类）就可以在高空中飞翔（驾驶飞机或滑翔机）,相对于生活在其他地区的人需要特殊装置才能飞翔,这正是一种突破,而且这里讲的正好是人的形态.
明白了吗?
