Some people might say that understanding the past is nothing to do with solving the problems of the present and future. In my opinion, however, in order to solve the problems of the present and future, it is important to understand the past: we can find the causes of the problems in the past and solutions from precedents in the past.
First, understanding the past enables us to discover the causes of the current or future problems. It is generally said that most problems of the present or future are related with the past because of the continuity of time. Therefore, in order to find the causes of the problems in the present and future, it is necessary to understand the past. For example, global economic crisis stems from the past finance policies or practices. Also, the environmental problems are the result of past human activities and development policies. The difference of the economical or political status between South Korea and North Korea, also can be explained by understanding the past history. In this way, (지금여기서 여러가지 case들을 들으셨는데, 그것보다는 좀더 구체적으로 갔으면 좋겠네요. 하나를 의내용을 담아주세요 그런다음에 그내용으로 바탕하여 에쎄이를써보시면 좋을것같아요.) we can say that in order to solve the current and future problems, we are required to understand the past.
Second, we can find the solution of the problems from precedents in the past. Some people might say that since the situations or conditions of the past are different from those of the present and future, it is hard to find the proper solutions in the past. However, there are common or similar things throughout human history. Therefore, in most cases, we can find the precedents of current issues and get some advice (조언은 셀수 없어요) advises or solution from them. According to the research, (쉼표필요없습니다.) conducted by the Korea Times, more than eighty percent of social scientists say that they often study past precedents to find the solution regarding to the present and future issues. They also say that by doing that, they could find useful solutions or even discover possible problems and prepare for them. In this way, we can say that understanding the past is good way to find solution of the current problems. (여기서, 해결책은 찾을 수 있는데. 정확히 어떻게 해서 해결책을 찾을 수 잇는지, 그런것들을 언급해주시면 좋을것 같은데. 약간 좀 아쉽네요.)
In conclusion, for the above reasons, I strongly think that it is essential to comprehend the past to solve the problems of the present and future.
Comment: 전반적으로 글은 잘 쓰시는것 같아요. 문제점도 거의없습니다. 하지만 제가 위에서 언급드린점 꼭 참고해주시길 바랄게요. 전체적으로 약간 redundancy가 있고 읽기 약간 지루한 에쎼이같아요.. 반복되는 느낌이 너무많아요 . 그래도 잘쓰셨어요 ㅎㅎ 수고하셨습니다. ^^
