耳朵是我们身体自然声音的侦查器，解析声音以便我们理解。

 1 

Ears help in Taste   耳朵有助味觉

We’re not saying that you can really taste food with your ears, but they do have a function in transmitting taste signals to your brain. There is a division of nerves called the chorda tympani（鼓索） that just happens to run throughout the middle ear as it connects the undergo（经历） buds（蓓蕾） on the face of the tongue to the brain.

不是说你靠耳朵品尝食物，但耳朵可以把味觉信号传到大脑。有种神经称为鼓索，恰巧贯穿中耳，连接大脑和舌头表面的味蕾。

Structure 结构

The complete area of the central ear is not large, the internal ear is of about the size of a pencil eraser, but it has more than 20,000 hairs.

中耳完整的面积并不大，内耳大约是卷笔刀大小，毛发却多达2万根。

3

Keep Working 一直工作

The ear continues to have the intellect of hearing sounds, but your brain just shuts them off. Possibly that’s why you at times all of sudden wake up when you listen something optimistic, but with no thought what it was.

耳朵持续不断听声音，而大脑却会屏蔽。也许就是为何你有时候听到什么好事突然醒过来，但不知道究竟是什么。

4

 Avoid Hairsprays少喷发胶

If you frequently apply hairspray, it might cause several painful problems in your ears. It is because your ears are so near to your hair, while hairspray is applied, more times it can acquire into the ear, causing earwax（耳屎） that would of course fall out to get jammed.

如果你频繁喷发胶，有可能会引起耳朵疼痛。因为耳朵离头发近，喷发胶的时容易进入耳朵，耳朵结块堵住耳道。

5

Cleaner 清道夫

Ears itself are self-cleaner. Pores（小孔） in the ear canal（道） fabricate（制造） cerumen（耳垢）, or ear wax, and minute hairs, called cilia（纤毛）, move forward the wax out of the ear.

每个耳朵都可以自洁。耳道孔里产生耳垢，而称之为纤毛的细小毛发把耳垢赶出去。

6

New Ear Every Year每年都新生

You get a novel ear canal each year. The ear canal skin is continually increasing external at rate of 1.3 inches each year.

每年你耳朵都重获新生。耳道肌肤表皮每年都增长1.3英寸。

Say NO to Headphones拒绝耳机

Wearing headphones create a great habitation for bugs, alike to a swamp. Immediately in an hour the figure of bacteria in your ear increases by 700 times and a general signal for ear infections is itching ears.

戴耳机给虫子创造沼泽般的栖息地。仅一个小时耳朵里的细菌就增长700倍，一般耳朵感染的标志就是耳朵痒。
