    At night, you fall asleep while listening to beautiful music. In the morning, you are woken up by the singing of birds outside. You can enjoy all of these things because of one important organ—the ears. March 3 is Ear Care Day. It helps us remember the importance of our ears and encourages us to take good care of them.

You may wonder: how do the ears work? The ear has three different parts: the outer ear, the middle ear, and the inner ear. The outer ear is the part you can see. It collects sound around you. The sound then travels down to the middle ear, the inner ear and then to your brain.

Your ears never stop working, even when you are asleep! Your ears continue hearing sounds, but your brain just ignores(忽视) them. That’s why you may sometimes wake up suddenly in the middle of the night—your brain hears something, but you don’t know what it is, since you are asleep.

More surprisingly, ears even help with tasting food. Of course, you don’t actually taste food with your ears. But there are nerves running through the middle ear that connect the tongue(舌头) to the brain. If something happens to your ears, you may have a hard time telling different tastes apart, according to the website of People’s Daily.

The ears are truly important organs with many functions(功能,作用). You should make sure to protect your own ears as well as you can. There are some Dos and Don’ts you need to know.

First of all, when the sun is shining, wear some sunscreen on your ears. And during winter, cover your ears with a hat or a scarf. Secondly, dry your ears with a towel after swimming or having a bath. If you feel water in your ear, shake your head a little bit. This can help you get the water out of your ear.

Besides, don’t listen to music on your earphones for too long. Follow the 60: 60 rule: listen to music at 60 percent of the maximum volume(最大音量) for no more than 60 minutes a day. Also, it’s not a good idea to share earphones with friends. When you have only one earphone, you might turn the volume up too high, since one earphone isn’t loud enough.
