Sweeping the whole development of the knowledge and去掉吧！ as well as the achievements in each academic field, broadly speaking, the knowledge is the process of accumulation, and the achievements would be regarded as the milestones of the every step that human beings explore and research the universe. So, in my view, the past achievements have a large deal of value in both nowadays and future advancement of science.

Admittedly, some people would be worried about that if strongly concentrationif 引导的应该是个句子 on the past achievements, the influence of the past great people’s idea and theory would be a restriction in following human's creativity. For instance, in the 19century, many physicists believed in Newton's Mechanics firmly even when with the progress of science some rules would not accord with the facts in practice. In some sense, when one admires the greatness of the past and abandon individual’s idea and belief, the past achievements could cover human's insightful eyes and limit oneself in the fence of the thought.

Whereas, I would wonder whether those who attained the original work are never touch the past achievement or ever researched on them. Each person's life is limited, one cannot explore and find out all the rules and truth in one field within the length of his/her/ his or her life. At the first step, one must learn about the basic rules in past achievements, for the past discoveries and knowledge are like the bottom part/foundation of a building, and one's task is to continue what the predecessors could not do and add the bricks in order to a higher building for descendants. Therefore, researching on the past work, not only does one can save the enormous sums of time and endeavor to study and prove the known rules and truth once more, but help to discover some flows and improve theory system as well.

Furthermore, one can also learn from a concrete example to ensure the importance of the past achievements to today's progress, no matter how remarkable or fallacious they are. As we all know, one of the greatest scientists Einstein, who to some extent deny the absolutely correctness of Newton's classical rules create the Relativity. Actually, when pointing out the limits of the Newton’s classical rules, Einstein’s Relativism is a complement in the field that the Newton’s rules cannot reach----that microscopic world. If Einstein would never learn the Newton’s classical rules, how could he find out some flowsflaws in the theory. None of new research and discoveries could be produced without foundation. Only when Einstein studied the past achievements, assumed the truth of the rules and apply them into practice, did he ultimately establish the better and more accurate theory on the bases of the classical mechanics.

All in all, studying the past achievements is essential and influenced by them are inevitably. Yet, what the most important is how to deal with the difficulty when confronting with the contradiction between the past work and today's new discoveries-----believing in the past achievements totally or fearlessly draw up the doubt. In another word, scientists should have the capacity of extracting the essence and repelling the dreg while studying the past achievements. Only the one make the efforts on the past achievements with the passionate for creativity and exploration, will he/she attain his/her achievements some day.

不错唉！总体思路还是很清晰的，论据能够论证你的论点，其实例子多一段我觉得没啥毛病的，我看老美的很多文章里也有这种现象的，实在没什么可写的就多加几个例子，不存在什么重不重复的问题，反复例证更具说服力嘛！都说老美喜欢用例子说话嘛~~~
我现在是固定套路了，（1） 题目中是两者比较的，第一段就找出作者支持的那方面的优点；第二段就是它的不足；第三段就说另一方面的好处及补充作用！ （2） 剩下的题目我现在都倾向于用因果因果论证法论证，第一段有原因就分析原因，没有原因就挖掘原因进行分析，然后对原因论证一番；第二段，原因如果不正确就分析其缺陷，如果正确的话，就分析原因不能完全证明结果；第三段，对结果进行论证和修正。
我自己也知道很俗，但是如果把套路固定下来的话能省不少脑筋，而且熟能生巧哦~~

一顿乱说，见笑~~

衷心祝愿你尽快找到感觉，还有多贴文章，我现在有充分时间给你改作文了
