Do you know how    1    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.

    2    (put) simply, the existence of mirror neurons suggests that     3     we see someone else do something, our brains imitate it, whether or not we actually perform the same action. This explains a great deal about     4     we learn to smile, talk, walk, dance or play sports. But the idea goes     5    (far)：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. Recently, researchers       6    (find) that mirror neurons relate strongly to language. A group of researchers discovered that     7     they gave people sentences to listen to (for example: “The hand took hold of the ball”), the same mirror neurons were triggered     8     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     9    (function). However, it is not yet known exactly how these discoveries might help find treatments for social disorders．

Research does mirror that neurons seems to provide us with even more information concerning how humans behave and interact. Indeed, it may turn out to be the equivalent for neuroscience of what Einstein’s theory of relativity was for physics. And the next time you feel the urge     10    (cough) in the cinema when someone else does-well, perhaps you’ll understand why．
