眼睑上有个小洞，你可能从未注意过

There's A Little Hole In Your Eyelid That You Probably Never Noticed.

eyelid：眼睑；

眼睑上有个小洞，你可能从未注意过

Science classes can teach you about an awful lot, from why dogs look like wolves to the nature of reality, but it always seems to avoid getting to the bottom of one burning question: what the hell is that tiny hole on the bottom of your eyelid?

an awful lot：极多

avoid：回避

burning：燃烧；强烈

getting to：达到

seems to avoid getting to：似乎是为了避免；

科学课可以教你很多东西，从为什么狗看起来像狼，到现实的本质，但它似乎总是回避一个紧迫的问题：你眼睑下的那个小洞到底是什么？

Well, first things first, this fleshy little pinprick is completely normal. Some people's are larger and more obvious than others. However, if you go up close to a mirror, most people should be able to see a small almond-shaped hole around 2 millimeters away from the inner corner of each lower eyelid.

first things first：事有先后

fleshy：多肉的，肥胖的，肉质的

pinprick：点，孔，针孔，烦心的小事

obvious：明显

almond-shaped：杏仁形

millimeter：毫米

好吧，首选，这个肉质的小针孔是完全正常的。有些人比其他人更大，更明显。然而，如果你靠近镜子，大多数人应该能在每只眼皮的内角大约2毫米远的地方看到一个杏仁状的小洞。

This is scientifically known as your lacrimal punctum.

scientifically：科学地；合乎科学地；按科学的方法

lacrimal：泪骨；泪腺肿瘤；泪道

punctum：刺点；小点；斑点

这在科学上被称为你的泪点

The hole does not produce tears, although it is part of your eye's guttering and drainage system. It's also the reason why you get the sniffles after you cry.

guttering：排水沟

drainage：排水

sniffles：抽鼻子

这个没并不会产生眼泪，尽管它是你眼睛的排水沟和排水系统的一部分。这也是你为什么在哭完后会抽鼻子的原因。

As mentioned, it doesn't produce the tears themselves. That job is, of course, given to the tear duct. The hole's task is to drain these tears. It's a bit like the oping of a canal that connects the eye to the lacrimal asc.

mention：提到，写到，说到；提及，说起，写上一笔；

drain：耗尽，排出，排干；

tear duct：鼻泪管；

canal：运河；沟渠；管道；

lacrimal：泪腺的；

asc：气囊；

正好说到的，它自己并不会产生眼泪。这项工作，当然，是由泪管完成的。这个洞的任务是排干眼泪。它有点像打开一条连接眼睛和泪囊的管道。

From that asc, the tears drain through the lacrimal duct into the nose, hence why you get a runny nose after you shed a few tears or why you can sometimes tasts eye drops at the back of your throat.

hence：因此，由此；从此，从现在起；

runny：流鼻涕

shed：棚屋；去除，摆脱；落泪；蜕皮；脱毛；落下；脱落；

eye drops：眼药水

at the back of：作为……背后的原因；

throat：咽喉，喉咙；

泪水从泪囊流出，通过泪腺管排进鼻子，这就是为什么你流了风滴眼泪后会流鼻涕，或者为什么你有时会在喉咙后面学到眼药水的味道。

The next part is not for the faint-hearted.

faint-hearted：胆怯的，怯懦的；胆小鬼；

faint：虚弱的，微弱的，微小的；

hearted：有……心的；

下一部分不是给胆小鬼看的；

There's a medical procedure that involves placing tiny cylinder-shaped plugs into these holes in order to stop dry eyes. This helps to stop the eye from draining so much fluid out, keeping is moist, healthy and better at fending off infections.

medical：医疗的，医学的；

procedure：手术；程序，步骤，手续；

involve：需要，包含牵涉，影响，要求，参与；

cylinder-shaped：圆柱体；

in order to：为了；

draining：使枯竭的；使疲惫的；

fluid：液体，液体；

moist：湿润；

fend off：挡开；避开；

infection：感染，传染；

有一种医疗手术，需要将小圆柱形插头放入这些孔中，以阻止眼睛干涩。这有助手阻止眼睛排出过多的液体，保持眼睛湿润、健康，并更好的抵御感染。

See, who would have thought a tiny hole in your eye could so interesting?

看，谁会想到眼睛上的小没会这么有趣？
