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 beat--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(包含) about 100 billion neurons(神经元)-it would take you, over3, 000 years to count them al. 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 neuron creates only a little electricity, all your neurons together can produce enough electricity to power a light bulb.
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 computers have your brain'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 learn things that you will use in the future? The structure(结构) of your brain changes every time you have a new thought,remember or learn 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.
It's true that there are some bad people on the internet. They try to get your money or information. So it is necessary to be careful of the internet. However, staying safe online doesn't ask you to turn your internet off. The following advice will help you keep away from dangers on the internet. ●Check the links(链接) carefully You may often need to click(点击) links when you check your emails or read online. Before clicking them, you should make sure they are safe. There's a good way to tell whether a link is safe. First, put the mouse over it and the full link will appear near the mouse. Then you can check whether this link is an official(官方的) website. If it is, then you can click it. ●Don't share your personal(个人的) information You should never tell others your own information online, such as your family information and bank information. You should also know that anything you post on the internet may stay there online for a long time. So, be careful about anything you post on the internet. ●Remember to use a safe public Wi-Fi If a public Wi-Fi is open for everyone, it may be not safe. You'd better not use such a Wi-Fi. When you have to use one, don't enter in(输入) any personal information. |
