Fair and square

Some monkeys seem to have a highly developed sense of fairness

EVERYBODY loves a fat pay rise. Yet pleasure at your own can vanish if you learn that a colleague has been given a bigger one. Indeed, if he has a reputation for slacking, you might even be outraged. Such behaviour is regarded as “all too human”, with the underlying assumption that other animals would not be capable of this finely developed sense of grievance. But a study by Sarah Brosnan and Frans de Waal of Emory University in Atlanta, Georgia, which has just been published in Nature, suggests that it is all too monkey, as well.

The researchers studied the behaviour of female brown capuchin monkeys, which have all the necessary ingredients to capture the public imagination. They look cute. They are good-natured, co-operative creatures, and they share their food readily. Above all, like their finicky female human counterparts, they tend to pay much closer attention to the value of “goods and services” than males (although why this is so remains a mystery).

Such characteristics make them perfect candidates for Dr Brosnan's and Dr de Waal's study. The researchers spent two years teaching their monkeys to exchange tokens for food. Normally, the monkeys were happy enough to swap pieces of rock for slices of cucumber. However, when two monkeys were placed in separate but adjoining chambers, so that each could observe what the other was getting in return for its rock, their behaviour became markedly different.

In the world of capuchins, grapes are luxury goods (and much preferable to cucumbers). So when one monkey was handed a grape in exchange for her token, the second was reluctant to hand hers over for a mere piece of cucumber. And if one received a grape without having to provide her token in exchange at all, the other either tossed her own token at the researcher or out of the chamber, or refused to accept the slice of cucumber. Indeed, the mere presence of a grape in the other chamber (in the absence of an actual monkey able to eat it) was enough to induce sullen behaviour in a female capuchin.

Dr Brosnan and Dr de Waal report that such behaviour is unusual in their trained monkeys. During two years of bartering prior to these experiments, failure to exchange tokens for food occurred in fewer than 5% of trials. And what made the behaviour even more extraordinary was that these monkeys forfeited food that they could see—and which they would have readily accepted in almost any other set of circumstances.

The researchers suggest that capuchin monkeys, like humans, are guided by social emotions. In the wild, they are a co-operative, group-living species. Such co-operation is likely to be stable only when each animal feels it is not being cheated. Feelings of righteous indignation, it seems, are not the preserve of people alone. Refusing a lesser reward completely makes these feelings abundantly clear to other members of the group. However, whether such a sense of fairness evolved independently in capuchins and humans, or whether it stems from the common ancestor that the species had 35m years ago, is, as yet, an unanswered question.

总体介绍

这是2003年9月18日刊登在《经济学家》（The Economist）杂志上的一篇科技类文章。文中主要论述猴子的公平感---像人一样，对不公平待遇有怨恨。从文章的题材上讲，科技类的文章是考研英语阅读的四大题材之一(另外三类是经济评论、文化教育和社会生活)，而且这篇文章谈论的是较新的科学研究成果（《自然》杂志刚发表的文章），以简介的形式出现于《经济学家》杂志，自然很适合做考研英语阅读的出题文章。从体裁上看，这是一篇典型的说明文，属于考研英语阅读的常见体裁之一。这篇文章共有6段，520词，如果用作考研英语阅读理解的一篇，则段落和字数都有些偏多。因为该部分的文章一般要求将字数控制在400词左右；文章段落数一般为4-5段，便于出题。

这篇文章被用于2005年的考研英语阅读理解部分第一篇，距发表时间仅一年多，试题序号为21-25。文中加下划线的部分是被删除的内容。改编后的文章共5段，426词。

原文改编

命题人主要对原文进行以下几方面的改编：

一、删去文章标题。文章标题概括文章的主题，如果出现，文章大意就未睹先知。为了测试对文章主题和其他内容的理解，阅读理解原文的标题都要删去，让考生根据文章的内容去总结和把握。如这篇文章的副标题Some monkeys seem to have a highly developed sense of fairness在考题中就未出现。

二、压缩文章字数。为了把文章字数控制在要求的范围内，可有可无的细节、不影响文章总体结构的细节内容都要删除。这篇文章第二段的划线部分和第五段全段被删去的原因就是如此。

三、替换超纲词汇。为了将超纲词汇控制在要求的范围内（全文的3%），也为了便于考生真正发挥阅读水平，有些超纲词汇被替换。如这篇文章第四段末句中的sullen behaviour（sullen为超纲词汇）在考题中被替换为纲内词汇resentment。

四、改编其他方面。有时，为了使文章语言更加精炼，结构更加严谨，在删去部分内容后，相邻段落被合并。为了使上下文连贯起来，有时也改写原文。

改编后的文章不仅没有破坏原文的结构和内容，反而显得更加精炼：结构严谨，层次清晰。第一段以人为类比---人对于不公平待遇的反应是非常愤怒，接着指出研究者最近通过对僧帽猴的分组实验证明这不仅仅是人类的特性，也是猴子的特性。这是研究结论。后面是对有关实验的各个方面的叙述：如第二段的实验对象的选定，第三段和第四段的实验的具体内容。末段与第一段相呼应，并指出僧帽猴的公平感在进化上的起源还无法确定。
