2008年考研英语阅读理解冲刺重点预测25篇之第16篇

   In 1966 Allen and Beatrice Gardner, two psychologists at the University of Nevada in Reno, had a bright idea. They were interested in the evolution of language and the linguistic capabilities of great apes. Previous attempts to teach chimpanzees to talk had ended in failure and the matter was considered by most people to be closed. But the Gardners realised that speech and language are not the same thing. Many deaf people, for example, are unable to speak but are perfectly able to communicate by gestures that have all the attributes and sophistication of spoken language. Given the very different anatomies of the human and chimpanzee larynx, the Gardners suspected that previous experiments had failed because chimps are physically incapable of speech.

   They therefore decided to try teaching a chimpanzee to sign in the way that deaf people do. And their chosen subject, a female chimp named Washoe after the county in which the university campus is located, proved an adept pupil. Though there is still debate about whether what Washoe learned was really equivalent to human language, there is no doubt that she learned a lot of words. She now has a vocabulary of about 200. All of this, however, raises a second question. If Washoe and her successors can learn a complex and arbitrary vocabulary of gestures from people, do they have such vocabularies naturally? To examine that possibility Amy Pollick and Frans de Waal, of Emory University in Atlanta, Georgia, have looked at gestures and expressions in chimpanzees and their cousins, bonobos.

   Signalling by facial and vocal expression is ubiquitous among primates. Signalling by gesture is confined to the great apes. The researchers' hypothesis was that the meaning of expressions has been hard-wired by evolution whereas the meaning of gestures is learnt and, at least to some extent, is arbitrary. If that were true, particular sorts of facial and vocal expression would occur only in particular contexts, and that this would be consistent across groups and even species. The same gestures, by contrast, would be used in different contexts.

   The researchers found exactly what they expected. Expressions (“silent bared teeth”, “relaxed open mouth”, “pant hoot” and so on) almost always occurred in the same contexts in different groups and different species. Gestures (“hard touch”, “reach outside”, “slap ground” etc) did not. Half of the gestures Dr Pollick and Dr de Waal regularly observed seemed to have completely different meanings in the two species. Moreover, even within a single group, the meaning of a gesture could vary with context, almost as tone of voice can vary the meaning of a human's spoken word.

   It is also worth remembering that gesture is still a crucial part of human language, even for those with normal hearing. The old joke that the way to render an Italian speechless is to tie his hands together has a kernel of truth in it. Evolution does not come up with complicated structures in a single leap. They are built up step by step. This study suggests that the step of speech may have been built on mental attributes that were acquired millions of years ago when the ancestors of apes and men began to wave meaningfully at each other.

   难句突破

   The researchers' hypothesis was that the meaning of expressions has been hard-wired by evolution whereas the meaning of gestures is learnt and, at least to some extent, is arbitrary.

   主体句式  The researchers' hypothesis was that…

   结构分析  这个句子的难点在于that之后的这个宾语从句。从句以whereas为界可以分为两个部分，其中后半个句子由whereas引导与前半个句子为并列结构，此外at least to some extent是一个插入语，一定程度上干扰和混淆了is learnt 和is arbitrary这两个结构的并列关系。

   句子译文  研究者的假设是，表情的意义在长期的进化过程中已经成为一种天生的能力，而手势的意义是后天学成的，至少在一定程度上是任意的。

   题目分析

   1．B. 细节题。文章第一段的主要内容就是讲述卡德勒夫妇对于黑猩猩语言能力试验的新想法，因此答案显而易见。

   2．C. 细节题。文章第二段中指出，Washoe的成就使科学家们提出了新的问题，并进行了进一步的研究，因此C选项正确。

   3．B. 细节题。文章第三段第一句话指出，“通过表情和声音来发送信号的现象在灵长类动物中是普遍存在的。但只有大猩猩才能用手势发送信号”，并不存在两者那个更加复杂的说法。

   4．A. 语义题。从该词所在句子的上下文中，可以推出表情具有固定的意义，成为了动物一种天生的能力。

   5．D. 推理题。文章比较后一段的比较后一句话指出，人类祖先在使用手势的时候很可能促使了脑部的发展，从而渐渐产生了语言能力，因此答案为D。

   参考译文

   1966年，内华达大学雷诺分校的两名心理学家阿伦与比特里斯·卡德勒夫妇产生了一个聪明的想法。他们对于大猩猩的说话和语言的进化能力非常感兴趣。前人研究曾试图教黑猩猩如何说话，但那些努力比较终都以失败告终，很多人认为这个领域已经没有什么可以研究的了。但是卡德勒夫妇意识到说话和语言并不是一件事情。比如说，许多聋哑人不能说话，但是他们却能够用手势进行充分的交流，这些手势都包含了人类语言的那些特点和精细度。由于人类和黑猩猩喉咙的结构不同，卡德勒夫妇认为前人研究的失败是因为黑猩猩生理上就无法说话。

    因此，他们决定试着教一只黑猩猩如何使用聋哑人的手势。他们选择的研究对象是一个名为Washoe的雌性黑猩猩，研究地点就在该大学的校园里，实验将她培养成了一个能熟练使用手势的学生。尽管人们仍在争论Washoe学会的到底能不能算人类语言，但是毫无疑问她学会了很多词汇。她现在的词汇量约为200个单词。所有这些都使人们提出了第二个问题。如果Washoe和她的继任者们能够从人类那里学会复杂和任意的词汇，那么他们是不是天生就拥有这些词汇呢？为了验证这种可能性，亚特兰大埃默里大学的爱米·波利克和弗朗斯·德瓦尔对一些黑猩猩和他们的近亲倭黑猩猩的手势和表情进行了研究。

    通过表情和声音来发送信号的现象在灵长类动物中是普遍存在的。但只有大猩猩才能用手势发送信号。研究者的假设是，表情的意义在长期的进化过程中已经成为一种天生的能力，而手势的意义是后天学成的，至少在一定程度上是任意的。如果这个假设成立的话，那么各种特别的脸部表情和声音就只会在特殊的情境下才能发生，而且在物种群甚至是物种之间都是一致的。相反，同样的手势却能够在不同的情境下使用。

    研究结果正如预期。不同的物种群以及物种之间都会在相同的情境下使用一些表情（“不出声地张嘴露齿”、“放松地张嘴”、“高声气促”等），而却不会用相同的手势（“硬碰”、“向外伸手”、“互相打击”等）。波利克和德瓦尔博士规律性地观察到的近半手势在两种动物之间的意义几乎都是完全不同的。此外，即使是在一种动物内部，一个手势的意义可能在不同的情境下有所变化，就像人类说话时用不同的声调可以表示不同的意义那样。

    我们应该记得手势仍然是人类语言中一个至关重要的组成部分，即使是对那些没有正常听力的人来说。有一个老笑话说，如果要让一个意大利人闭嘴，那就把他的手绑起来，这个笑话有其道理所在。进化的过程不会一步就达到复杂的结构，而是一步一步演化过来的。该研究间接地说明了，当我们的猿人和人类祖先开始有意义地向彼此挥手的时候，这种脑力思考的特点就在一步步地向语言能力发展。
