英语口语表达之 “鼻屎”是什么呢？

what's a booger? 

不管你是长大了的好奇宝宝。还是长不大的“十万个为什么”，“人体大探索”都将成为你认识自己的好决定！鼻屎是什么？头发是怎么长出来的？为什么会流血？这些问题，你是不是都困惑过？当初，你找到谜底了吗？答案就在这里！

Hey, get your finger outta there! Instead of picking them out, let's learn about those little blobs. Yeah, we're talking about boogers.

嘿，把你的手指拿出来！别再抠了，我们一起来研究一下这些小货色。没错，我们要说的正是鼻屎！

To understand what boogers are, you need to know about mucus. Mucus is the sticky, slimy stuff that's made inside your nose. You may have another name for nose mucus: snot. Your nose and sinuses make about 1 liter of snot every day.

要理解鼻屎，咱们就要先来认识黏液。黏液是我们鼻子里黏稠又粘滑的液体，你也能够叫它鼻涕。你的鼻子跟鼻窦每天要分泌出大略一升的鼻涕。

Mucus has a pretty important job — it protects the lungs. When you breathe in air through your nose, it contains lots of tiny things, like dust, dirt,英语培训, germs, and pollen. If these made it all the way to the lungs, the lungs could get infected, making it tough to breathe. Luckily, snot helps trap this stuff, keeping it in the nose and out of the lungs.

鼻涕有个非常重要的作用，就是保护我们的肺。当我们平时用鼻子呼吸的时候，会吸入空气中的很多杂质，比如灰尘、尘土、细菌、花粉等。假如这些杂质直接进入到我们的肺里，那么肺就可能受到感染，使呼吸艰难。幸好，我们有鼻涕，鼻涕可以把杂质隔绝出肺而留在我们的鼻子里。

After this stuff gets stuck inside the nose, the mucus surrounds it and some of the tiny hairs inside the nose called cilia. When the mucus, dirt and other debris dry and clump together,英语培训, you're left with a booger.

这些留在鼻子里的杂质会被鼻涕跟鼻毛给包住。鼻毛就是鼻子里的那些微小毛发。当鼻涕、灰尘和其余杂质变干后，结块了，就成了鼻屎。

Boogers can be squishy and slimy or tough. Everybody gets them, so they're not a big deal. In fact, boogers are a sign that your nose is working the way it should!

鼻屎可以是湿软的，也可能是粘滑的，或者硬邦邦的。每个人都有鼻屎，这没什么大不了。事实是，如果你有鼻屎，那说明你的鼻子在认真工作！
