北師大版高中英語(yǔ)模塊7--Unit 21 Lesson2-2

[00:02.63]Amazing, isn't it? [00:04.38]Makes a normal computer look simple, [00:06.15]doesn't it? [00:07.98]So, what do we know about this organ [00:09.99]called "the brain"? [00:11.66]Scientists who study the brain [00:13.18]and the nervous system have learnt a lot [00:14.97]about it in the last ten years. [00:17.29]Like explorers exploring the world, [00:19.67]they've mapped different areas of the brain [00:21.72]which are responsible for different functions. [00:24.69]We now know which parts of the brain [00:26.89]are related to different parts of our body [00:28.89]and feeling from them. [00:31.18]A good example of this can be seen [00:32.70]in people who have lost an arm or a leg [00:34.73]in an accident. [00:36.36]Though they don't have an arm or a leg [00:38.43]they can still have feelings from it,like pain. [00:41.17]Incredible isn't it? [00:43.41]And these areas of our brain control [00:45.39]all our movements. [00:47.59]Right, now just put up both of your arms. [00:50.82]That's right, put thme both up. [00:55.22]Now to do that, a specific area of your brain, [00:58.59]responsible for your arm movement, [01:00.42]had to send out electronic impulses [01:02.27]to your arms. [01:04.20]It's really quite a complicated operation. [01:06.76]OK, you can put your arms down now! [01:08.20]
