SAT作文-Can knowledge be a burden rather

1、However, due to the European’s deep research about the gunpowder rather than Chinese’s negligence, gunpowder’s wider utilization stimulates the modern military development, making killing more faster and cruel这里用强调句更好一些. Had it not been for the utilization of knowledge of gunpowder, countless number of innocent people would not have been dead这里用表示动作的词更好 optionally. 哨忌

From ancient time till present days, the problem of the knowledge has been sparking a hot debate. For more rational and deep aspects, 

knowledge can be considered as an unavoidable burden .

2、Knowledge has been updating every day. As time goes by, some knowledge will be 这里不用主将从现is outdated that they can not function as well as before. New things in the past 30 years ago这里的表达意思不明确 can not be treated as useful as before. Therefore, knowledge cannot always act as a beneficial part in our life接下来这一句与前面内容的逻辑不够严谨，前面缺少细节支持，这个结论有点突兀. 

If insisting on previous rather than advanced knowledge, sometimes less perfect consequence will appear这一句逻辑主谓不一致. 整体来看前面三句话和论点说的是一个意思，调整一下简化为凝结性强的一个句子就可以了，这里需要解释论点，不是简单的复总央驼述或改写：accompanying development, new ideas, new theories, and new researches spring up and in return, it is new exploration promotes revolutionary changes, ground-breaking achievements and epoch-making breakthroughs, because only new things cater to new times and can ignite new development. On the contrary, what is outdated  can essentially hinder progress. China’s last dynasty Qing perished due to their stubborn idea that they were the most powerful nation in the world so that they had no need to communicate with other countries. 

3、Owing to Qing’泉板s closed policy, China did not make progress as the European countries did hence fell behind the world, resulting in the following failure in the Opium Wars.

4、Incorrect consideration towards knowledge. Since people do not have enough base knowledge to explore new things, side effect often appears. It is people’s deep exploration through unknown fields and technology based on known knowledge that edify people to discover more new things, which either bought benefit and burden for human. Nuclear energy should be a reasonable illustration in this point. Nuclear energy was discovered and started being utilized in last century. The exceeding and unprecedented found use realized people’s enormous demand towards energy. However, nuclear energy, as a new type of breakthrough in science, is dangerous itself so that it could not be controlled well by people, leading  making thousands of people died from or affected by the damage brought by the unscientific utilizations of nuclear energy. During the World War two, the American launched two A-bombs at Hiroshima and Nagasaki in Japan, which almost destroyed the two cities and caused thousands of people to be dead, meanwhile exerted a severe radiation influence on local district. In 1986, the most serious nuclear disaster took place in Chernobyl, Russia, killing 31 people in three months, then led almost 80 thousand people to be dead in the later 15 years. Moreover, the damage and pollution of that accident still hurt people nowadays. Although the knowledge of nuclear energy brought us hope in the future development of science, it also threaten the world as a burden. Lead sb to do=lead sb into doing  lead to sth/doing

5、In brief, knowledge, acts as a intricate concept, not always benefit people as it looks like superficially. Taking account of the boundedness itself and the appropriate utilization, knowledge exists with a risk of being a burden.
