In this argument, the arguer concludes that we can expect the amount of electricity used by the cooper-extraction industry to decline significantly due to that new copper-extracting technologies can use up to 40 percent less electricity than the older method to process the same amount of raw ore.[这句话太长了,分成两句,用逗号分开,不然看着很累噢] Close scrutiny of the cited evidence, however, reveals it lends little support to the arguer’s conclusion.
To begin with, the arguer fails to establish the causal relationship between the fact that the electricity used in copper-extraction is 40 percent less when we switch to new copper-extraction technologies and the claim that the amount of electricity will decline significantly when we switch to new copper-extraction technologies. [这句话也是一样的长,建议分成两句,而且你说的causal relationship意义不是很明确。最重要的,你把总用电量不必然减少这个错误提到前面来写了,本来应该是在后面的吧,如楼上所讲的,这个也不是因果错误,而是incomplete thoughts 错误] The claim that the electricity used in copper-extraction is 40 percent less is under the precondition that the amount of the ore instead of copper is equal. It is highly possible that when extraction the same amount of copper, the electricity consumed in new copper-extraction is equal to, even more than that in older method of copper-extraction. Before drawing any conclusion, the arguer should make sure that not only the amount of ore but also the amount of copper extracted is equal when comparing whether the newer or the older method is more electricity saved.
Furthermore, another flaw that the arguer makes is that he or she fails to take the proportion of copper into consideration. Since the fact, as the arguer points out, that 40 percent saved electricity is especially works when the proportion of copper in the ore is high. Contrarily, when the proportion of copper is low in the ore, the older method works. And besides, the arguer also gives us the information that the proportion of copper in the ore can vary considerably. Possible [。。这个楼上指出来了] is that the majority of the ore is of low proportion of copper and therefore we can not say that the new method is worked in extracting those ore with low proportion. Even if it works, little evidence support that is will save 40 percent electricity as expected since the fact that 40 percent saved electricity is worked especially when the cooper in ore in of high percent. Possible is that the new technologies of copper extraction will cost electricity as much as, or even more than the older method in extracting the ore with low proportion of copper.
Additionally, according to the two possibilities discussed above, whether the new technologies will put into mass copper extraction is open to doubt. Since that when extracted the same amount of copper, the new method of copper extraction has the possibility of consuming more electricity, the new copper-extraction technologies will not be adopted. What’s more, for the fact that the proportion of copper in the ore can vary considerably, as the arguer claims, use either of the two is not a sage way to save electricity, since each of them have their merits in special condition. So we should not adopt the new copper-extraction technologies instead of the older one, no mention to expect it will lead to the significant decline of electricity.
To sum up, this argument is unpersuasive as it stands. To make it more convincing, the arguer must provide detail information about extracting the same amount of copper which method is more electricity saving. What’s more, to bolster this argument, the arguer should take the percent of ore with high proportion of copper into consideration. [结尾的建议可以题的,范文里面有,而且ETS也灭有说什么,确切的讲,ets对结尾不是很关心。]
[In conclusion, 你没有必要非得弄成三段,这个不是定好的。其次要注意批判的顺序,这点对于行文的层次和理清自己的思路是非常关键和重要的,
楼上指出来的,我就不重复了。
加油:)]
我的在这边,帮忙拍下哈
