In the statement, the author concludes that the Mason City council will need to increase its budget to(改为for) improvements to the publicly owned lands along the Masson River, in order to increase therecreational use of the river. However, the argument suffers from several flaws which make the statement unconvinced(改为unconvincing). To begin with, the author cites some surveys to indicate that Mason City residents consistently rank water sports as a favorite form of recreation.(这一句只是复述原文,不能构成TS) However, the author fails to provide enough information of the surveys. (和上一句合成一句构成TS)Unless the surveyor sampled a sufficient number of respondents and did randomlyacross the entire spectrum, the survey results are not reliable to gauge the overall condition of residents in Mason City. Even the statement don't provide me the total number of respondents and the percentage of them who rank water sports as a favorite form of recreation, so I don't know whether the surveys ensure representativeness. Without more convincing and valid information of the respondents of the surveys, the author cannot persuade me. The author also provides the complaints about the quality of the water in the river which confirm that the residents avoid the river just because if(改为of) the quality of the water.和上一段同样的问题The author overlooks a possibility that the complaints are caused by the residents who merely care about the environment along the river, the living condition and health, instead of whether the river is suit for people to have fun in the Mason River. The foregoing possibility may make the author's statement dubious. Furthermore, even it is possible for Mason City to improve the condition of Mason River, whether the solutions and the projects can reach its ultimate goal is still dubious, although the agency responsible for rivers in their region has announced plans to clean up Mason river. However, the author doesn’t provide me the evidence that whether they can afford and complete the project well. In other words, perhaps, it is difficult for people there to clean the river completely, for it all depends on extent of the pollution of the river. Even the river becomes clean enough for people to take any recreational activity after the project, the recreational use of the river may not increase.与上一段构成让步,不错 On one side, although the residents regard water sports as a famous form of recreation and even they take Mason River as a good place, they may change their views. One the other side, The river is not suit for swimming, fishing or other activities. Both foregoing possibilities make it impossible. To sum up, the argument suffers several logical flaws, which make it unconvincing. 每写一句话就问why,分析的就会透彻了,多学习范文,会有好处的。打字平时抽时间用软件练一下,几天就可以了。 |
