Question

At night, you fall asleep while listening to beautiful music.1.You can enjoy all of these things because of one important organ (器官) — 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.2.The sound then travels down to middle ear, the inner ear and then to your brain.

But ears do more than hear.4.In the inner ear, there are organs that are filled with liquid and covered in small hairs. When you move your head, the liquid and hairs move, too. They send messages to your brain about the position (位置) of your head.
