Question

【题目】Do you know how it is when you see someone yawn and you start yawning too? Or how hard it is to be among people laughing and not laugh yourself? Well, apparently it's because we have mirror neurons (神经元）in our brains.
Put simply, the existence of mirror neurons suggests that every time we see someone else do something, our brains imitate (模仿)it, whether or not we actually perform the same action. This explains a great deal about how we learn to smile, talk, walk, dance or play sports. But the idea goes further: mirror neurons not only appear to explain physical actions，they also tell us that there is a biological basis for the way we understand other people.
Mirror neurons can undoubtedly be found all over our brains，but especially in the areas which relate to our ability to use languages，and to understand how other people feel. Researchers have found that mirror neurons relate strongly to language. A group of researchers discovered that if they gave people sentences to listen to (for example: "The hand took hold of the ball"), the same mirror neurons were triggered as when the action was actually performed (in this example, actually taking hold of a ball).
Any problems with mirror neurons may well result in problems with behavior. Much research suggests that people with social and behavioral problems have mirror neurons which are not fully functioning. However, it is not yet known exactly how these discoveries might help find treatments for social disorders.
Research into mirror neurons seems to provide us with even more information concerning how humans behave and interact(互动).Indeed, it may turn out to be the equivalent (相等物)for neuroscience of what Einstein's theory of relativity was for physics. And the next time you feel the urge to cough in the cinema when someone else does—well, perhaps you'll understand why.

Answer 1

【答案】

【1】C

【2】A

【3】A

【4】D

【解析】试题分析：本文是一篇科普说明文。介绍了镜像神经元的作用。

【1】推理判断题。从第二段的第一句话“every time we see someone else do something, our brains imitate it”可知镜像神经元的作用就是当我们看到别人做某事，我们也会跟着做。故选C。

【2】词义猜测题。根据第三段镜像神经元对语言的作用，当人们听到“手抓住球”这句话时，神经元就开始起作用了，就像手抓住球这个动作真的发生一样。set off：出发；触发。故选A。

【3】细节理解题。根据最后一段第一句可知答案。故选A。

【4】主旨大意题。本文主要介绍了人体镜像神经元的作用。故选D。
