问题 单项选择题

科学家认为,手是使人能够具有高度智慧的三大重要器官之一,其余两个器官是可以感受到三维空间的眼睛和能够处理手眼传来的信息的大脑。在400万年的进化中,人类的手逐渐演变成了大自然所能创造出的最完美的工具。
无论是远古还是现代,手都象征着人与神的活动,象征着权力、创造与智慧,对手的崇拜可以在不同的文明中见到。
手相不只是江湖术士的花言巧语,科学也对此深感兴趣。研究表明,手指,特别是食指和无名指的长度,与人体的健康有关联。手指的生长和大脑的发育是在同一时期发生的,并且都与子宫内性激素的水平有关。如果孕妇怀孕期间睾丸素水平较高,生下的孩子就更容易成为左撇子,也更容易日后得心脏疾病或孤僻症。女性的无名指往往与食指一样长或者更短,男性的无名指则往往长于食指,而左撇子的无名指通常比食指长出许多。另外,无名指长于食指还是有音乐天分的表现。
在哺乳动物中,人类的手独一无二。大拇指同其他四个手指相对的结构是人手的最大优越性,许多类人猿可以将自己的拇指和食指对合,但不能将拇指与中指、无名指以及小指对合,因为它们的手指不够柔韧。只有人类的手指十分灵敏,可以感觉到振幅只有0.00002毫米的振动。研究发现,大脑在说话时会变得活跃的那一部分,在做手势时同样也会活跃起来。科学家还发现,大脑控制手的活动的区域,分布在运动中枢里几个不同的部位,面积达到大脑皮层的四分之一。一个简单的手的动作,例如举起一杯牛奶送到嘴边,会使大脑皮层出现特别强烈的兴奋,这一直是令神经学家不解的谜。

对“在哺乳动物中,人类的手独一无二”这句话的意思理解不正确的是( )。

A.人类对手的崇拜可以在不同的文明中见到

B.人类的手指十分柔韧十分灵敏

C.人类手的简单动作会使大脑皮层出现强烈兴奋

D.人类的大拇指有同其他四个手指相对的结构

答案

参考答案:A

解析: 第四段对人类的手与类人猿进行比较,指出人手更灵活、更柔韧,因而是独一无二的,B项理解正确。由文中“一个简单的手的动作,例如举起一杯牛奶送到嘴边,会使大脑皮层出现特别强烈的兴奋”可知,C项理解正确。“大拇指同其他四个手指相对的结构是人手的最大优越性。”D项也说明了人手的独一无二。

For the person keeping a journal, whatever he experiences and wants to hold he can write down. But to get it down on paper begins another adventure. For he has to focus on what he has experienced, and to be able to say what, in fact, the experience is. What of it is new? What of it is remarkable because of associations in the memory it stirs up? It is a good or bad thing to have happened? And why, specifically? The questions multiply  (增多) themselves quickly. As one tries to find the words that best represent this discovery, the experience becomes even clearer in its shape and meaning.

Beyond the value of the journal as record, there is the value of the discipline it teaches. The journalist begins to pay closer attention to what happened to and around himself. He develops and sharpens his skills of observation. He learns the usefulness of languages as a means of representing what he sees, and gains skill and certainty in the expression of his experiences. To have given up one’s experience to words is to have begun marking out the limits and potential of its meaning. In the journal that meaning is developed and clarified (澄清、阐明) to oneself. When the intention of the development of that meaning is the consideration of another reader, the method of the journal redirects itself and it becomes the essay.
