大学英语精读：第一册 UNIT 95000字 Throughout the ages different ideas have been expressed about the working of the human brain. It is only recently, however, that science has begun to give us some idea of how the brain really works. 简历大全 /html/jianli/ The BrainThe Most Powerful Computer in the Universe 作文 /zuowen/Man still has a lot to learn about the most powerful and complex part of his body the brain. 简历大全 /html/jianli/In ancient times men did not think that the brain was the centre of mental activity. Aristotle the philosopher of ancient Greece thought that the mind was based in the heart. It was not until the 18th century that man realised that the whole of the brain was involved in the workings of the mind. 开题报告 /html/lunwenzhidao/kaitibaogao/ During the 19th century scientists found that when certain parts of the brain were damaged men lost the ability to do certain things. And so, people thought that each part of the brain controlled a different activity. But modern research has found that this is not so. It is not easy to say exactly what each part of the brain does. 作文 /zuowen/ In the past 50 years there has been a great increase in the amount of research being done on the brain. Chemists and biologists have found that the way the brain works is far more complicated that they had thought. In fact many people believe that we are only now really starting to learn the truth about how the human brain works. The more scientists find out, the more questions they are unable to answer. For instance, chemists have found that over 100,000 chemical reactions take place in the brain every second. Mathematicians who have tried to use computers to copy the way the brain works have found that even using the latest electronic equipment they would have to build a computer which weighed over 10,000 kilos. Some recent research also suggests that we remember everything that happens to us. We may not be able to recall this information, but it is all stored in our brains. 毕业论文Scientists hope that if we can discover how the brain works, the better use we will be able to put it to. For example, how do we learn language? Man differs most from all the other animals in his ability to learn and use language but we still do not know exactly how this is dine. Some children learn to speak and read and write when they are very young compared to average children. But scientists are not sure why this happens. They are trying to find out whether there is something about the way we teach language to children which in fact prevents children from learning sooner. 毕业 Earlier scientists thought that during a mans lifetime the power of his brain decreased. But it is now thought that this is not so. As long as the brain is given plenty of exercise it keeps its power. It has been found that an old person who has always been mentally active has a quicker mind than a young person who has done only physical work. It is now thought that the more work we give our brains, the more work they are able to do.Other people now believe that we use only 1% of our brains full potential. They say that the only limit on the power of the brain is the limit of what we think is possible. This is probably because of the way we are taught as children. When we first start learning to use our minds we are told what to do, for example, to remember certain facts, but we are not taught how our memory works and how to make that best use of it. We are told to make noted hut we are not taught how our brains accept information and which is the best way to organise the information we want our brains to accept.This century man has made many discoveries about the universe the world outside himself. But he has also started to look into the workings of that other universe which is inside himself the human brain. 思想汇报 /sixianghuibao/ NEW WORDScomputer 总结大全 /html/zongjie/ n. machine that stores information and works out answers 计算机 毕业universe 毕业论文n. 宇宙 开题报告 /html/lunwenzhidao/kaitibaogao/ complexa. difficult to understand or explain 错综复杂的，难懂的 简历大全 /html/jianli/ancient 作文 /zuowen/a. in or of times long ago 古代的；古老的 论文代写philosopher 作文 /zuowen/ n. 哲学家 论文代写philosophy 作文 /zuowen/ n. 哲学 论文代写 involve 总结大全 /html/zongjie/vt. cause to become connected or concerned 使卷入 开题报告 /html/lunwenzhidao/kaitibaogao/ working 简历大全 /html/jianli/n. （usu. pl.） operation; action运转，运行，活动 思想汇报 /sixianghuibao/ability 作文 /zuowen/n. 能力 开题报告 /html/lunwenzhidao/kaitibaogao/exactly 毕业论文ad. with complete connected or concerned确切地；精确地 作文 /zuowen/ amount 总结大全 /html/zongjie/n. 数量，数额 思想汇报 /sixianghuibao/chemist 总结大全 /html/zongjie/ n. one who studies and understands chemistry化学家 思想汇报 /sixianghuibao/biologist 毕业论文n. one who studies the life of animals and plants 生物学家 毕业 biology 简历大全 /html/jianli/ n. 生物学 简历大全 /html/jianli/complicated 简历大全 /html/jianli/n. difficult to understand, complex难懂的；复杂的 chemical 论文代写a. of chemistry 简历大全 /html/jianli/unable 作文 /zuowen/a. not able 简历大全 /html/jianli/reactionn. 反应mathematician 总结大全 /html/zongjie/ n. one who studies and understands mathematics数学家 毕业equip n. 设备，装置 作文 /zuowen/kilo = kilogram 毕业论文公斤，千克 论文代写recent 毕业论文 a. done or made not long ago 近来的recall 论文代写vt. remember记得；回忆起differ 总结大全 /html/zongjie/vi. be different （from） 总结大全 /html/zongjie/ mentally 开题报告 /html/lunwenzhidao/kaitibaogao/ad. 智力上，脑力上 总结大全 /html/zongjie/physical 思想汇报 /sixianghuibao/ a. of the body; of matter; of the science of physics身体的；物质的；物理学的 总结大全 /html/zongjie/ potential 毕业论文n. 潜力 开题报告 /html/lunwenzhidao/kaitibaogao/limitn. 局限，限度PHRASES & EXPRESSIONS 毕业论文putto （good） use 总结大全 /html/zongjie/use （in a profitable） （好好）利用differ from 作文 /zuowen/be dissimilar to 与不同 简历大全 /html/jianli/compared to / with 开题报告 /html/lunwenzhidao/kaitibaogao/ in comparison with 与相比 思想汇报 /sixianghuibao/make notestake notes 记笔记look into 论文代写examine 调查，观察PROPER NAMES 作文 /zuowen/ Aristotle 思想汇报 /sixianghuibao/亚里士多德 论文代写 Greece 毕业 希腊 论文代写
