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).

So exactly how fast does your brain work? Well, imagine this: a bee lands on your foot. Neurons in your skin send this information to your brain at a speed of more than 240 kilometers per hour. 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.

阅读下列短文,根据短文中的信息完成文后表格。在答题卡标有题号的横线上,写出空缺处所填单词的正确形式。(每空一词)

Many people think dreams are full of messages that may not be clear to us common people. But if we think about what is going on in our lives, we can usually come up with an answer. Let’s look at some of the most common dreams. What are the meanings of these dreams?

Falling

You’re falling, falling, falling… and then you wake up. This dream is said to mean you are in fear of something or worried about something. There may be something in your life that is out of control and there is nothing you can do to stop it. Another explanation is that you may experience failure in something. Maybe you’re not doing well in school or work.

Taking an exam (or forgetting that you have one)

You suddenly realize you have to take an exam at that very moment. You might be running here and there to find your classroom. Scientists say this dream may mean you’re being tested about something or maybe you are facing a challenge.

Flying

Dreaming that you are flying means you are on top of things. You are in control of the things that matter to you. It may also mean you have confidence in yourself and think no one and nothing can beat you.

Trying to run, but going nowhere

You’re trying to run, but either of your legs won’t move or you simply aren’t going anywhere. Some scientists think this dream means you’re trying to do too many things at once and can’t catch up or move forward.

In fact, unlike these dreams, there are also many strange dreams that scientists may not be able to explain.
