The following appeared in an editorial in the Mason City newspaper.
"At present, Mason City residents seldom use the nearby Mason River for any kind of recreational activity, even though surveys of the region's residents consistently rank water sports (swimming, fishing, and boating) as a favorite form of recreation. Since there have been complaints about the quality of the water in the river, residents must be avoiding the river because they think that it is not clean enough. But that situation is about to change: the agency responsible for rivers in our region has announced plans to clean up Mason River. Therefore, recreational use of the river is likely to increase, so the Mason City council will need to increase its budget for improvements to the publicly owned lands along the Mason River."
------------------------------------------------------------------------
In this argument the arguer assume the fact that the residents of Mason City who are believed to be water sports lovers seldom use Mason River for recreational activity due to they think the river was not clean enough. And the arguer further claims that the situation is about to change for plans to clean up the river has been announced. Thus, the arguer draws the conclusion that the recreation use of the water will probably increase and the city council should increase budget for improving the public owned lands along the river. This is a problematic conclusion based on several unfounded assumptions.
Firstly, based on a survey, the arguer assert that the residents of Mason love water sport, but no information of the survey is provided, such as who conducted the survey, when was the survey conducted, how many people responded to the survey, and can the respondents represent all the citizens of Mason. Without the information above, we can not be sure that the survey is reliable, thus, we can not be certain that the residents of Mason truly prefer water sports. And maybe it is just because they do not love water sports so they seldom use Mason River for recreational activity.
Secondly, even if the residents are all water sports lovers, the arguer fails to establish a cause and effect relationship between the poor quality of the water and the low frequency of river using. There may be a host of other reasons for the residents to avoid using the river for recreational activity. It is possible that the river is too shallow for boating, to cold for swimming, or too noisy for fishing. And maybe the weather in Mason is so severe, that the river is frozen for most of the years, and waterside recreational activity like swimming and boating can hardly be done. And maybe it is because of the terrible environment along the river cease people to go to the river and play.
Thirdly, admitting that the seldom usage of Mason River for recreational activity is indeed caused by the poor quality of the water. The arguer cannot convince me that the situation will change soon after the announcement of the cleaning up plan. The residents of Mason who already have aversion towards the dirty river may not change their mind so easily. Probably only when the government carries out the plan and truly reverses situation of Mason River, will the residents begin to enjoy themselves in Mason River.
Fourthly, it is unfair for the arguer to assert that the government should increase the budget on river side public owned land as a result of the possible raise of river using. Maybe the public owned land is just a small portion in the total waterside land, the improvement on them will do little to help attract more people, or maybe the waterside land owned by the public is already in good condition, enough to satisfy most of the residents. Without precluding the situation above, the arguer can not say for sure that more investment on public owned land along Manson River is needed.
All in all, if the arguer does not provide more evidence about the situation of Mason residents as well as the condition of Mason River, and adjust the conclusion, this argument is completely a failure.
自评:
第二次限时 超了一两分钟 有色的段落是后来写的
还算言之有物
花在开头上的时间和笔墨都太多了 导致有一个错误没有来得及批
比第一次限时效果好得多,因为下笔之前思路就比较清楚~~继续加油ing
