问题 单项选择题

人类为什么能够区别左右奥秘在于人类的左右大脑是不对称的!动物的大脑是对称的,因而动物不能区分左右。这一设想最初由奥地利物理学家马赫提出。如今已有实验证明,马赫的洞见是正确的。我们的右脑与直觉、情感有关,左脑与逻辑、语言有关。在日常生活中,我们经常也会有这样的体验:一时想不起某物或某景的抽象名词,但却能在大脑中生动地再现其具体模样。这就是左右大脑分工的不同。人类正常的思维活动有赖于左右脑的合作,否则这个世界在我们眼中就会变得荒唐不堪。 这段文字意在表达:

A.能够区别左右,是证明人类高于动物世界的关键所在

B.左右大脑的不同分工及合作是人类认识世界的关键

C.我们的右脑与直觉、情感有关,左脑与逻辑、语言有关

D.人们总是钟情于对称之美,但有时创造性恰恰寓于不对称中

答案

参考答案:B

解析: 这段文字主要论述的是:人类能够区别左右的奥秘在于人类的左右大脑是不对称的,正是左右脑的分工与合作使得人类的思维活动得以正常运转,从而认识和改造世界。B项符合题意。
