眼眉是扮靓我们容貌不可缺少的一个部件，首先是因为人人都习惯了有一双眉毛，要是没有可就如怪物一般；其次，漂亮的眉型会让人看起来更美丽。但是，这其实只是眉毛的附加功能。它最基本的功能是帮我们挡水。就让下面这篇文章来为您解释一下吧。

    Those tiny, little hairs above our eyes that many women either pluck, paint, pierce or tattoo play a very important role in keeping moisture out of our eyes.

    Just like an umbrella keeps our bodies dry from the rain, our hairy eyebrows keep our eyes dry from rain or sweat.

    When it's pouring rain outside or when sweat drips down from our foreheads, our eyebrows divert the flow of water or sweat away from our eyes.

    Our arch-shaped eyebrows angle the rain or sweat around to the side of our faces--leaving our eyes fairly dry. By catching the water or sweat, our eyebrows not only allow us to see more clearly, but also keep salty sweat from burning or irritating our eyes.

    Eyebrows have other roles also. As one of our most expressive facial features, eyebrows help us determine how people are feeling without ever really asking them.

    If a person's eyebrows are frowning, chances are they are mad or upset. In addition, eyebrows have an increasing impact on our beauty or fashion culture over the years.

    Thick, hairy and big eyebrows tend to be characterized as unattractive while thin and plucked eyebrows are said to be more attractive.
