   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 neuron 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 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.

(1)、From the passage we know that neurons          .

A、receive messages very slowly B、are only found in your skin C、send messages to your brain D、need electricity to work
(2)、In Paragraph 3, the writer mentions computers to          .

A、compare them which the human brain B、show how fast they have become C、say that computers have no abilities D、ask people to use computers more
(3)、When you have a new thought,           .

A、your brain will power a light bulb B、your heart beats faster C、you remember something D、the structure of your brain changes
(4)、The article is mainly about          .

A、all the steps when your brain learns things B、what an unbelievable organ the human brain is C、how the brain makes people smarter than computers D、the things you can do to make your brain work faster
举一反三
   People cannot reach an agreement on the use of science and technology. For example, will radiation from electronic equipment destroy the environment? Should medical scientists change gene structures to prevent genetic disease or to create “more perfect” human beings? While people are arguing about these and others, technology continues to influence our everyday lives—the home, health and education, entertainment and communication, and so on.
   Some people carry on active social lives with computers —their own or the ones in public places like cafes, social centers, libraries, and so on. Communicating with others in chat rooms,  computer users can get to know people they might never meet in traditional ways. With live online video connections, two people with cameras in their computers can see and talk to each other from separate places.
   With modern telephone technology, most people stopped writing lettters—especially personal letters and notes. But now, writing to communicate has returned in electronic form, or e-mail, which is a way of sending messages from one computer to another. For some computer users, the wish to communicate intelligently or creatively with others makes them want to write better.
   Computer technology has also made it possible to run a house electronically. From turning lights on and off to starting the coffee and cooking the hot meal, computers are taking care of people at home. Many modern machines have computer chips that allow their owners to program them. For instance, you can “instruct” a microwave oven how to cook a dish. Most entertainment equipment operates with computer technology too. Computers can even start cars automatically so that on cold winter mornings you can get into a warmed-up vehicle and drive off.
   Although much of the technology in our everyday lives has good effects, there are some uses that raise questions. For example, are interactive media ( i.e., a combination of television, telephone, and computer) going to control minds, cause people to forget about family life and personal relationships? What effects will the genentic engineering of food have on people's health? High-tech medical treatments can make a person live a much longer life, but can they improve the health and happiness of human beings? Only time will tell, but, in the meantime, science and technology will continue to move forward.
