If your ears are working well, you hear sounds all the time. You can't switch(关掉) your ears off, even when you are asleep.

Listening

When you really want to listen to something, you tell your brain to focus on that sound. If your ears are healthy and are both working well, they can turn down other sounds while you focus on what you want to hear. If one ear isn't working as well as the other, they can't do this. If your hearing cells(细胞) have been damaged by too much noise or music, what you want to hear can get mixed up and lost in the other sounds around. With__healthy__ears__you__can__choose__what__you__want__to__listen__to,__but__you__can't__choose__what__you__hear.

Understanding

Your brain deals with the received sounds and tells you what they mean. Some people have problems understanding what they are hearing because their ears don't work well and they don't hear all the sounds. The brain does not get enough information to understand the messages or they may be mixedup.

Selective(选择的) hearing

Lots of mums and dads think that kids have this “problem”. They think that the kids select what they are going to hear and what they can't hear! Many mums say that dads do this, too. In fact, this is something we may all do to try and make our lives a bit easier. Some children wrote what they liked to hear and what they didn't like to hear.

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.

We see with our eyes and taste with our tongues. Ears are for hearing, skin is for feeling and noses are for smelling. Would anyone say that ears can smell, or that tongues can see? Actually, yes. Paul Bach-y-Rita, a scientist at the University of Wisconsin, believes that the senses can changeable. For example, a tongue can be used for seeing. The brain, as we know, is a complex organ(复杂的器官). Even when part of it is hurt, it will try to carry out the same function by sending the function to another area of the brain.

A college student was asked to take part in an experiment. In the experiment, his eyes were covered with a small video camera. The camera was connected to a long plastic line which went into his mouth. A computer would change the video’s picture. The picture would travel through the plastic line as an electric current(电流), reaching the electrodes(电极板) inside the student’s mouth. The scientist would roll a ball towards his right side, left side, or centre, and the student would have to catch it. When the scientist rolled the ball, pain passed over the student’s tongue. For the position of the pain on the tongue, the student reached out his hand and caught the ball.

If the brain can see a ball through a camera and a wet tongue, blindness and deafness can be overcame.
