argument108随机抽得，第二个习作
第二个argument,应该比第一个（28）有进步吧？请指教
TOPIC: ARGUMENT108 - The following appeared in a Brenton newspaper.

"The Brenton power plant draws water from Scott's River for its cooling system and releases the warmed water back into the river. The town council recommends that the plant install a more efficient cooling system that uses less water, claiming it will be more environmentally sound. However, in Uptown, where the new system is used, a study found that the complex network of pipes in the new system tends to accumulate algae. The build up of algae can be avoided by scrubbing the pipes, which is costly, or by adding an herbicide to the water in the pipes to prevent algae accumulation. But water containing the herbicide cannot be released back into the river and it is known that low water levels can harm river ecosystems accustomed to higher levels. Therefore, Brenton power plant should continue to use the old cooling system exclusively."

conclusion-- the town council recomends the Brenton power plant continue to use the old cooling system
reason1--two town different,maybe the water quality different
reason2--the arguer fails to consider other meatures to solve herbicide
reason3--new system may not affect the water level

Based upon the argument above, the town council recomends the Brenton power plant continue to use the old cooling system. To support this recommendation, the arguer cites the unsatisfing experience of the Uptown, where the more efficient  cooling system is installed for the environmental purpose. Also, the arguer cites a study of the complex network of pipes in the new system-which tend to accumulate algae- to support the recommendation. The reasoning of the argument is problematic in several respects.

First of all, the arguer cites the experience of Uptown-where the new system is used-to prove the merits of the new system. The arguer takes for granted that if the new system is used in the Brenton, the network of pipes tend to accumlate algae. However, the Brenton power plant draws water from Scotte's River for the cooling water, which may be different from the one Uptown draws. In that case, the water quality may be different. Perhaps, the water in Scott's River is  much more clear than that of Uptown, which is unlikely to accumulate the algae. All in all, the arguer fails to provide the detail information to indicate that both of the two towns draws water from te Scotte's River, that we can make an analogical deduction that the same thing will happen to Brenton.

Secondly, as it says in the argument, the water containing  the herbicide cannot be released back into the river, because of the harmful material in it. However, the arguer fails to consider other meatures to solve this problem. For instance, the toxics can be dealed before releasing back to the river. Perhaps the cost is not high, and the procedure is not complicated to add a sort of chemicals to the water to clean the herbicide in the cooling water. In this way, the power plant do not have to consider the ecosystem unbalance caused by the low water levels due to the new system. So the argument is not perfectly deduced, and the arguer has to consider all the possiblities that may solve the problems.

Moreover,  using less water-a special character of the new system-may not affect the water level, even if it does not release back into the river. As it mentioned in the argument, the new cooling system is more efficient that do not need much water. That is to say, with less water used for this system, the water level will not be affected. Actually, the water level is not easy to change, if it is only a small proportion comparing to the large amount of water in the river.The aruger fails to rule out this possibility and get an unconvincing conclusion to this argument.

To sum up, the recommendation to use the old cooling system is  unconvincing as it stands. To strength the argument, the arguer has to rule out all the possiblities mentioned above and provide more information to indicate the reasonings. Only in that way can the arguer convince the town council the make the decision.
