就在原始的帖子上面改的, 因为一开始没看到下面有修正后的^^ 有重复修改的地方还请包涵
In this argument, by introducing new cooper-extracting technologies which is believed to use less electricity than previous technologies, the author asserts that the amount of electricity used by the copper-extraction industry will decline significantly. However, this deduction commits several logical fallacies and is based on poor assumptions, which in return, greatly make the conclusion inconvincible.
Primarily, the argument fails to provide exactly similar experiment situation between new and old technologies, as a result, the 40 percent less electricity is not valid. As stated in the argument, the proportion of copper in the ore can vary greatly; additionally, the electricity used by different technologies largely depends on the proportion of copper in the ore. Therefore, only providing these two technologies process the same amount of raw ore, but not mentioning the proportion of copper in those raw ore, make the precondition of the comparison unfair. On the one hand, it is entirely possible that, the proportion of copper in the ore processed by new technologies is far higher than that processed by old one. In the delete other words, because of the high proportion of copper, it is easier for new technologies to extract copper out with less electricity. On the other hand, even though the copper are of the same proportion and the amount of ore is the same too, the amount of cooper we get at last by the new technologies is, for example, 50% of that by the old one. [原因呢?] As a result, the 40 percent less electricity appears favorable, but actually meaningless after analysis. Lacking the equal condition for the comparison, the author cannot simply justify the result.
Furthermore, granted that the new technologies are superior to old ones, should the total amount of electricity decrease consequently? Common sense tells us that, lots of factors may contribute to the amount of electricity. Firstly, no information is offered to demonstrate new technologies will be adopted by companies quickly. For instance, too expensive, or too complex may be the two possible reasons inhibiting the widely use of new technologies. Secondly, given that the new technologies are vastly adopted, and hence people may produce larger amount of copper than ever before due to the high efficiency of new technologies, which subsequently increase the amount of electricity rather than decrease. Without taking those factors affecting the amount of electricity into account, it is too hasty/ cursory to reach such a conclusion.
On balance, the unfair condition of comparison between two technologies, the incomplete thought of total amount of electricity used by the industry, both of which undermine the author's conclusion. ]这里可以借用alwaysbest的句式, the… the… both render… unsubstantial/ungrounded as it stands] To substantiate the conclusion, author is required to provide equal condition for comparison, and taking other factors related to the electricity used in to consideration as well.
这次的题目, 再考虑到限时写出来,已经不错了: )
句子感觉是不够精练.比如:
given that the new technologies are vastly adopted, and hence people may produce larger amount of copper than ever before due to the high efficiency of new technologies, which subsequently increase the amount of electricity rather than decrease.
这里before后面突然读到一个due to, 感觉有些突兀
论证上的问题见文内标注吧
加油^^
再回头看自己的, 感觉这次的argu实在写的不好.多多学习
