Your brain controls everything you do. It makes it possible for you to think, Learn, create and feel; to blink(眨眼) and breathe and for your heart to heat –this fantastic control center is your brain. It is so amazing that a famous scientist once called it " the most complex(复杂) thing we have yet discovered in our universe".
Can this small grey organ(器官) , which weighs less than one and a half kilos,
really do so much? Amazingly , your brain contains about 100 billion neurons(神经元) -it would take you over 3 ,000 years to count them all. Believe it or not, the activity in your brain never stops. Your neurons create and send more messages than all the phones in the world. And although one neumn creates only a little electricity, all your neurons together can produce enough electricity to power a light bulb (灯泡).

Your brain then uses other neurons to send the message back to your foot to shake the bee off quickly. These neurons can send this information at more than 320 kilometers per hour. No computer has your hrain's unbelievable ability to deal with the amount of information coming from your eyes, ears and other sensory organs.
But how does your brain allow you to leam things Lhat you will use in the future? The structure (结构) of your brain changes every time you have a new thought, remember or leam something. For example, riding a bike seems impossible at first, but soon you are able to do it. How? As you practice, your brain sends "bike riding" messages again and again Soon, the actions are learnt and you are able to ride a bike easily from then on.
