考研作文：人脑和电脑的不同

采用了适当的衔接手法，层次清晰；可适当增加从句的使用；作者在高级词汇方面要多下功夫，有些单词拼错了。

The most obvious difference between a computer and a brain is the ability of Thinking. A computer can be described as a caculator which can caculate out almost any mathmatic question in a very short time.But for a brain,it's quite hard.Then,here comes a very interesting paradox:Human beings are smart enough in inventing the computer but less smart than computer in manthmatics.Why?What I'd like to say is there's no need to be upset for this paradox.A computer can do lots of things better than a brain not just in math,but there's one thing a computer can never do better than a brain, which is thinking,even the famous computer company Lenovel has one computer brand names "Thinkpad". Artificial Itelligence has being a hot study which appleas thousands of secientits make effort for,but the progress can hardly be called as big.During a long history of biological evolution,human being,as the only creature which possess the ability of thinking,has used this unique skill to achive uncountable great invents. It's hard to say wheather there will be a invent as intelligent as a human brain or not in some day.Nowdays,at least,nothing can think as brilliant as human brain.I hope that one day Artificial Intellience can be used eveywhere around life,thus human being can save more energy and live better,and the world,too,would become more interesting. At last,I want to quote a slogen of Apple as the end of this passage,which is "think different."
