整体很好啊,水平不错的。大致的错误2楼指出了,我做点我的补充吧。Is it a grave mistake to theorize before one has data? I agree with the speaker that the general process of theorizing is based on sufficient data in order to avoid any undesired results. While the assertion has merits, not all pursuits for data are legitimate.Common sense informs us that any sound theory must come out by the support some data-regardless of the amount of the data. Consider the Newtonian physics. Only after hundreds of trial and experiment to collect sufficient data did the three laws of nature finally came into being. It attributes to the foregoing painstaking work and ample data that this theory is not overthrown until today. Or consider the theory of continents drift. It was inspired by an unmeant glance of the map; however, vast amount of data was explored and sought before it was finally theorized.I agree with the speaker's assertion insofar as theorize without any data can be meaningless and even dangerous. This assertion finds its support when considering the ultimate goal of theorizing: to simplify a chain of empirical facts with a common rule that can be easily understood and applied in related events. Query whether a theory can be called theory if it has no supporting data. Even if, in any events, we admit that it is a theory, the so-called theory is not conducive to a better understanding of the empirical world that we are engaged in. Actually, a theorizing process with no fundamental data risks our approach toward a clarified truth. For instance, the earth-centered Universe that was created by distant ancient ancestors stood in the way of scientists’ revolutionary proposal that the Sun is the real center. Despites the merits of the speaker's claim, I find it presumptuous in two important respects. On one hand, there are certain academic areas where theory is tested after rather than before it is proposed. Linguistics may serve as an apt illustration. Every new meaning of single word in a foreign language is guessed through ways such as body language, facial language in the first place, and then proved or revised in later communication. Thus truth can be reached other than the process of data to theory. On the other hand, with a zeal for more data, we may drive too far away in attaining data before theorizing. Also take the Newtonian physics as an example, endless data could be piled up if Newton was ready to pursue all the available information he could get. In that event, the unprecedented theory could (still) behatching at present.(这里假设牛顿拿了n多的数据,最好再说他迟迟不下结论,这样才支持你的论点) In sum, a certain amount of data is important and necessary to make a theory in general; however, over amount of data can lead us to the opposite direction toward reaching the truth(这里的反面只写了你的第二部分,不完整,最好把art也总结下).还有,引用范文太多了。
