题目：ARGUMENT71 - Copper occurs in nature mixed with other minerals and valuable metals in ore, and the proportion of copper in the ore can vary considerably. Until fairly recently, the only way to extract pure copper from ore was by using a process that requires large amounts of electric energy, especially if the proportion of copper in the ore is low. New copper-extracting technologies can use up to 40 percent less electricity than the older method to process the same amount of raw ore, especially when the proportion of copper in the ore is high. Therefore, we can expect the amount of electricity used by the copper-extraction industry to decline significantly.

In this argument, the author claims that by adopting new method of copper-extracting technologies, the amount of electricity used by the copper-extraction industry would decline significantly. To substantiate this claim, the author points that the method of new copper-extracting technologies can use up to 40 percent less electricity than old method, especially used ores whose proportion of copper is high; and that every copper extraction industry would adopt the new method. After a close scrutiny, however, in several respects, there is little credible evidence supporting this argument.

First of all, the threshold problem with the argument is that the author concludes that the new method will save more electricity than the old method. However, the author provides no information and evidences to support that new method will save more electricity than the old method, when new method used on the ore whose proportion of copper is low. As the author said, the way of extracting pure copper from ore required large amounts of electric energy, especially if the proportion of copper in the ore is low. It is high possible that when extracting coppers from the ore whose proportion of copper is low, the new method will cost no less amount of electricity than the old method. Lacking enough information and statistics to rule out the possibility, the author can not draw a conclusion that the new method will save electricity than the old one.

Secondly, even assuming the new method can save electricity, whether in the ore whose proportion of copper is high or in the ore whose proportion of copper is low, the author cannot claims that every copper-extraction industry would adopt the new methods. It is impossible for us to know whether the new method will increase the revenue of industry. Perhaps the way of using the new method is too difficult to master, many small industry would not do favor of the new method. Or perhaps if adopting the new method, the cost of industry will increase so that all industry would prefer to the old method. Without in details analyzing these and such other factors, the author can not expect us to take seriously that every industry would adopt the new methods.

Finally, even assuming every industry has adopted the new methods, the author cannot assert that the amount of electricity will decline significantly. The author fails to account into the possibility that due to the new method, the amount of extracted copper will increase therefore the additional amount of electricity of extracted copper will offset the amount of saved electricity. The total amount of electricity would maintain the same as the old level even surpass the old level. Without sufficiently taking into the possibility, the author can not conclude than the amount of electricity used by the copper-extraction industry will decline.

In sum, the author can not convince me that by adopting the new method of copper-extracting technology, the amount of electricity will incline in every copper-extraction industry. To better evaluate this argument, I would need more information that the new method will save electricity than old one in the ore whose proportion of copper is low. Furthermore, the author need provide evidence that every industry would adopt the new method and rule out abovementioned possibilities which will undermine this argument.

题目：ISSUE4 - "No field of study can advance significantly unless outsiders bring their knowledge and experience to that field of study."
字数：534
Do a field of study advance significantly, if outsiders would not bring their knowledge and experience to that field of study? The speaker claims so. It is true that in some sense, some people prefer to agree that a field of study can advance significantly itself, while other people have an opposite attitude. However, in my opinion, I would partially agree with the speaker's claims for some reasons substantiated by following discussions.

Admittedly, with the development of technology, there are countless interdisciplines appearing in the current world. Pay attention to the invention of computer which has increasingly changed the world. For example, in the realm of architecture, in the forepast time, architects usually need to cost a long time to paint the figure of architecture on the papers. Nowadays, owed to the using of technology of computer, architect can more easily devise the figure of building, bridge, and road, which has saved architects a lot of time and energy. In the realm of mathematics, due to the accuracy of computer, it is more convenient and accurate for mathematicians to calculate some difficult problems, therefore there is few errors concerned about the statistics of the study of mathematicians. It is no doubt that many technologies of science have interacted with each other.

Secondly, the fundamental reason I agree with the speaker is that by learning other knowledge and experience from other field of study, a person can stand at a higher stage to delve his field of study. For instance, if a person who studies the mathematics also has some basic knowledge of philosophy, he would not only deal with problems with methods of mathematic but also focus on them with different point of view. There is no better illusion than Henry, who was a famous football sportsman of the clue of Arsenal. Due to study the knowledge of physics, he have a effective way to release his strength and power and have a good way to protect himself hurting in the football games. From abovementioned cases, it is through study knowledge of other fields one can truly make a great advance.

However, when it comes to the independence of field of study, no one can deny the vital role of the individuality of each field. If a scientist do not delve his original field sufficiently, it is impossible for him to find the problems in his field and to rely on knowledge of other fields. A famous academician of Chinese academy of science as the head of mathematic in my university once said (and I paraphrase):"It is true that the other fields such as computer, biology and logic have an important influence on my study of mathematic, while the vital factor to my success is that I have a sound basic mathematic knowledge." Without the sound basic knowledge of original field, no scientist can rely on knowledge of other field to advance significantly.

In sum, without the interdisciplines, human can not make the great achievement. Without knowledge of other fields human can have high levels to delve problems. Whereas, it is important for us to sufficiently study our original field so that can effectively use knowledge of other field to make an immense advance.
