8月7日 In order to solve the problems of the present and the future, people should review the past.
What would you do when you face problems in your life? Just sitting down and trying to create the answer from nothing? or you may try to review your past experiences to find some similar questions, then see how these questions were solved. By doing this, one can not only save time, but also can have a better understanding of the present situation and prepare for the future. Therefore, I agree with the above statement, and my reasons as follows.
In the first place, learning from the failures of the past can help us avoid making the same mistakes again, at the same time, sucessful experiences help us solve similar problems. As an old saying goes:What has been will be again; there is nothing new under the sun. Therefore, by realizing and learning from the past, both individuals and countries could develop quickly with less setbacks. I would like to cite one of my own experiences in studying as an example. When I was in high school, I began to realize that the mistakes I made in the test will reappear in the next one if I did not correct them and review them regularly. I clearly remembered one mathematical equation that was very diffcult to understand competely. After relizing this quesion, I reviewed it for several time, untill it became familiar in my mind. Then, I synthesized all the problems related to this equation and analyized it carefully, the solutions to the similar questions linked to this knowledge all filled in my brain. Next time I confronted with this type of question, I could solve it quickly and accurately.
Another point to consider is that, learning from the past can help us do better in the present and move on in the future as well. In my opinion, review the past is not about remembering everything and knowing everything on a time line, but about analylizing people and societies, and interpreting the decisions that were made in the past in order to help us understand the events of our own time. For instance, the great depression during 1930s gave American the opportunity to relize their problems within the development of economy. Through the new deal, American economy recovered in only a few years and the development became more healthy and stable that before. By learning from this, other countries which confront with the same problems nowadays can also walk out difficulites like Americans.
In the end, I have to admit that some problems may never existed in the past, as a result there are no past experiences to learn from. In this case, reviewing the past becomes unnecessary under certain situations. These situations happen frequently in the scientific feild. One example of this is that little record could be used for scientists who study the outer space such as mars, the moon, or other objects out of our solar system. These scientists need update facilities to observe the objects they interested in, and think out new method to anlylize the imagines bring back by these facilities. But the new methods and facilities are also used by people who study the same objects in the past, and scientists can find some useful informaiton from the work of their forrunners.
In conclusion, some problems indeed have no counterparts in the past, that why innovation comes, at the same time the development of human beings. However, even innovatin is based the knowledge from the past, as a result, it is safe to draw the conclusion that review the past in important for people to solve the problems of the present and the future.
TPO 5 In the reading text, the author talks about three uses of the "great house" in New Mexico. On the contrary, the professor in the lecture casts serious doubts on the author's theories. He says that none of these theories are convincing. First, the author says that one of the uses of these houses are residential. However, the professor argues that there are not enough fire places inside these houses to ensure hundreds of families' daily cooking. The reason is that the fire places in the largest house can only support ten families, but the biggest house is large enough to be lived by one hundred of familes. Thus, the residential theory is totally unsounded. Second, the author also states that these houses could be used for storing maize. In contrast, the professor points out that there are not traces of spoiled maize on the floor. Furthermore, not one single of large container is found in these houses. As a result, although the space may be suitable to store large amount of food, the evidence which support this theory is no found. Third, the author hypothesises that houses may be used for ceremonies, because of the pots found in the mound in these houses. However, the professor points out that other materials such as sand, stone, and building material are also be excated in the mound. In the professor's opinion, the mound is most likely to be a trash pile. Construction workers who built these houses at that time put these materials as trashes in the mound. Then, the professor further explains that the pots might be throwed by construction workers after they ate their meals. In this case, the ceremonial theories is also unconvincing, according to the professor. |
