In this argument, by relying on the facts of doubled number of factories in Clearview town, increased levels of air pollution and 25% more patients with respiratory diseases, the author makes a final conclusion that current members of the town are not protecting environment, and thus residents of Clearview should vote for Ann Green in Good Earth Coalition rather than Frank Braun, current member of town council. This argument suffers from several critical fallacies.
In the first place, there is no clear causal effect(effect causal?) relationship between increased levels of air pollution and the assumption of current members not protecting environment. The air pollution issue has definitely multiple reasons, which the author hasn't ruled out. Perhaps, the climate has been changed dramatically. For instance, geographical causes, such as volcano eruption in the nearby area during the past year, can lead to bad air condition in Clearview. It is also possible that some companies continue to release smokes from their chimneys, resulting in polluted air in Clearview. 划线部分也源于市委没有保护环境,与火山爆发不是一回事As a consequence, even if the current members actually carry out acts concerning environmental protection, there will be still little effect of controlling the increasing levels of air pollution.
Secondly, providing that the local hospital has 25% more patients with respiratory diseases, the conclusion that current members don't protect the environment is rather unconvincing. There is no clear evidence indicating where these additional patients are come? from. Perhaps, they are not local residents in Clearview, but from nearby town. Thus, maybe there are fewer people in Clearview who has respiratory illness, but a great number of people from nearby town will come to Clearview hospital to get treatment. Moreover, the fact that the number of factories in Clearview has doubled is irrelevant evidence for the assumption that current members are not protecting environment.划线部分可以放到上段进行更深入的论述。
Finally, it is unfair to conclude that Ann Green, a member of the Good Earth Coalition, can certainly solve the environmental problems in Clearview, if he she is elected as mayor of Clearview. In the whole argument, there is obviously no evidence showing that Ann Green has any ability of advocating environmental protection. Thus, this imprudent conclusion may lead to a serious flaw of the Clearview newspaper.
As it stands, the argument is not well reasoned. To make a better conclusion, the author needs to investigate on all possible causes that lead to increased levels of air pollution. It is unjustifiable to make claims about current members before detailed survey has been done. Also, more comparisons, including not only the inclination of environmental protection but also other aspects regarding taxes, education and so on, should be conducted to make a final decision of who should be voted as next mayor.
题目最后的“问题一定会得到解决”我觉得也是个比较重要的纰漏。 |
