再没有比眨眼更平常的事了。据说人一分钟会眨眼15-20次。通常的解释是我们眨眼是为了使眼球润滑,也可以保证不被灰尘或其他杂物伤害。但是,研究人员发现,我们眨眼的次数远远超过满足这两种需要的次数。这又是什么原因呢?听听日本的科学家是怎么说的吧。 There is nothing more common than blinking. It is said that a person will blink 15-20 times a minute. The usual explanation is that we wink in order to make the eye lubrication, but also to ensure that no dust or other debris damage. However, the researchers found that we blinked far more times than needed to meet both needs. What is the reason for this? Listen to Japanese scientists how to say it.
