C
Working with a group of baboons (狒狒) in the Namibian desert,Dr.Alecia Carter of the Department of Zoology,Cambridge University set baboons learning tasks involving a novel food and a familiar food,hidden in a box.Some baboons were given the chance to watch another baboon who already knew how to solve the task,while others had to learn for themselves.To work out how brave or anxious the baboons were,Dr.Carter presented them either with a novel food or a threat in the form of a model of a poisonous snake.
She found that personality had a major impact on learning.The braver baboons learnt,but the shy ones did not learn the task although they watched the baboon perform the task of finding the novel food just as long as the brave ones did.In effect,despite being made aware of what to do,they were still too shy to do what the experienced baboon did.
The same held true for anxious baboons compared with calm ones.The anxious individuals learnt the task by observing others while those who were relaxed did not,even though they spent more time watching.
This mismatch between collecting social information and using it shows that personality plays a key role in social learning in animals,something that has previously been ignored in studies on how animals learn to do things.The findings are significant because they suggest that animals may perform poorly in cognitive (认知的) tasks not because they aren't clever enough to solve them,but because they are too shy or nervous to use the social information.
The findings may impact how we understand the formation of culture in societies through social learning.If some individuals are unable to get information from others because they don't associate with the knowledgeable individuals,or they are too shy to use the information once they have it,information may not travel between all group members,preventing the formation of a culture based on social learning.

答案:
【语篇解读】 本文是一篇科普说明文。剑桥大学的一些研究人员通过对狒狒的研究发现,影响狒狒学习成效的因素不是它们的智力,而是其性格以及对学习的渴望程度。这一研究结果也适用于人类社会:如果我们不善于与他人沟通或太胆怯而不能利用所得到的信息,那么会阻碍以社会学习为基础的文化的形成。
9.A 解析:推理判断题。第一段描述了研究人员如何开展这一研究的具体细节:把新奇的食物和熟悉的食物藏在一个盒子里,有些狒狒有机会观看另外一只狒狒是如何完成任务的,而另外一些狒狒则不得不自学完成任务,因此选A项“卡特博士研究的设计”,而非研究的“结果”“目的”或“重要性”。
10.D 解析:细节理解题。由文章第二段中The braver baboons learnt,but the shy ones did not learn...及第三段中The anxious individuals learnt...while those who were relaxed did not...这些对实验的描述可知D项“那些渴望学习的狒狒”符合题意。
11.C 解析:推理判断题。该词所在上文,即第二、三段提到在观察了别的狒狒之后,勇敢的、渴望学习的狒狒学到本领,而害羞的狒狒学了却不像别的狒狒那样去做;再根据between collecting social information and using it可知与“收集”和“使用”对应的是“观察别人但不跟着做”,即C项。
12.B 解析:细节理解题。最后一段首句The findings may impact how we understand the formation of culture in societies through social learning.意为“研究结果可能会影响我们如何理解社会文化的形成,该文化的形成是通过社会学习获得的”。换言之,作者认为我们的文化是通过social learning而形成的,与B项“互相学习”相呼应,而非“储存信息”“理解不同的人”或“在社会群体间传播”。
