    Sounds are everywhere. You have two cool parts — ears on your body that can let you hear the sounds.

The ear is made up of three different parts: the outer ear, the middle ear and the inner ear. These parts all work together so you can hear sounds.

The outer ear is the part that you can see. It moves the sound waves(波浪) to the part of the ear inside the head. Inside your ear, you have an eardrum(耳膜). The eardrum is a thin piece of skin. Sound waves push against the eardrum. This makes the eardrum vibrate. When it vibrates, it moves its tiny bones. The bones help sounds move along to the inner ear. Then you can hear the sounds.

Ears are very useful. With the help of your ears, you can hear any sound. Maybe the sound is as quiet as your cat. Maybe it is so loud, like a plane flying by. Hearing is one of the most important senses, and it allows you to communicate, to learn and to enjoy things like music.

Believe it or not, your ears can help you keep balance. If there’s something wrong with your ears, you may fall down easily.

Therefore, ears should be protected well. We should protect our ears from loud noises in the daily life: When you listen to music with headphones on, make sure that the sound is not too loud. Remember to take breaks after listening for a while and let your ears have a good rest.
