大學(xué)英語精讀：第一冊 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. 簡歷大全 /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. 簡歷大全 /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. 開題報告 /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. 畢業(yè)論文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. 畢業(yè) 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?yún)R報 /sixianghuibao/ NEW WORDScomputer 總結(jié)大全 /html/zongjie/ n. machine that stores information and works out answers 計(jì)算機(jī) 畢業(yè)universe 畢業(yè)論文n. 宇宙 開題報告 /html/lunwenzhidao/kaitibaogao/ complexa. difficult to understand or explain 錯綜復(fù)雜的，難懂的 簡歷大全 /html/jianli/ancient 作文 /zuowen/a. in or of times long ago 古代的；古老的 論文代寫philosopher 作文 /zuowen/ n. 哲學(xué)家 論文代寫philosophy 作文 /zuowen/ n. 哲學(xué) 論文代寫 involve 總結(jié)大全 /html/zongjie/vt. cause to become connected or concerned 使卷入 開題報告 /html/lunwenzhidao/kaitibaogao/ working 簡歷大全 /html/jianli/n. （usu. pl.） operation; action運(yùn)轉(zhuǎn)，運(yùn)行，活動 思想?yún)R報 /sixianghuibao/ability 作文 /zuowen/n. 能力 開題報告 /html/lunwenzhidao/kaitibaogao/exactly 畢業(yè)論文ad. with complete connected or concerned確切地；精確地 作文 /zuowen/ amount 總結(jié)大全 /html/zongjie/n. 數(shù)量，數(shù)額 思想?yún)R報 /sixianghuibao/chemist 總結(jié)大全 /html/zongjie/ n. one who studies and understands chemistry化學(xué)家 思想?yún)R報 /sixianghuibao/biologist 畢業(yè)論文n. one who studies the life of animals and plants 生物學(xué)家 畢業(yè) biology 簡歷大全 /html/jianli/ n. 生物學(xué) 簡歷大全 /html/jianli/complicated 簡歷大全 /html/jianli/n. difficult to understand, complex難懂的；復(fù)雜的 chemical 論文代寫a. of chemistry 簡歷大全 /html/jianli/unable 作文 /zuowen/a. not able 簡歷大全 /html/jianli/reactionn. 反應(yīng)mathematician 總結(jié)大全 /html/zongjie/ n. one who studies and understands mathematics數(shù)學(xué)家 畢業(yè)equip n. 設(shè)備，裝置 作文 /zuowen/kilo = kilogram 畢業(yè)論文公斤，千克 論文代寫recent 畢業(yè)論文 a. done or made not long ago 近來的recall 論文代寫vt. remember記得；回憶起differ 總結(jié)大全 /html/zongjie/vi. be different （from） 總結(jié)大全 /html/zongjie/ mentally 開題報告 /html/lunwenzhidao/kaitibaogao/ad. 智力上，腦力上 總結(jié)大全 /html/zongjie/physical 思想?yún)R報 /sixianghuibao/ a. of the body; of matter; of the science of physics身體的；物質(zhì)的；物理學(xué)的 總結(jié)大全 /html/zongjie/ potential 畢業(yè)論文n. 潛力 開題報告 /html/lunwenzhidao/kaitibaogao/limitn. 局限，限度PHRASES & EXPRESSIONS 畢業(yè)論文putto （good） use 總結(jié)大全 /html/zongjie/use （in a profitable） （好好）利用differ from 作文 /zuowen/be dissimilar to 與不同 簡歷大全 /html/jianli/compared to / with 開題報告 /html/lunwenzhidao/kaitibaogao/ in comparison with 與相比 思想?yún)R報 /sixianghuibao/make notestake notes 記筆記look into 論文代寫examine 調(diào)查，觀察PROPER NAMES 作文 /zuowen/ Aristotle 思想?yún)R報 /sixianghuibao/亞里士多德 論文代寫 Greece 畢業(yè) 希臘 論文代寫
