写的第三篇,有点慢,45分钟的样子,希望有人可以来拍一下!顺便想要问下,这样按照北美套路的开头有没有问题,我几乎是原话复述了,自己感觉还是很有问题的。
ARGUMENT55 - The following appeared in a Letter to the Editor of the Shady Village newspaper.
"Commuters are complaining that the rush hour traffic on Blue Highway between Shady Village and Bright City has doubled their commuting time. Some commuters have asked that an additional traffic lane be built, but the recent creation of such a lane on nearby Green Highway apparently attracted more commuters, judging from the fact that rush-hour traffic jams actually increased there this past winter. To reduce rush-hour traffic on Blue Highway, a bicycle lane should be added instead of a traffic lane. This approach will succeed because many citizens of Shady Village are avid bicyclists; 75 percent of respondents to a recent questionnaire distributed there said they would like to bicycle more hours per week than they currently do."
In this letter, the author assumes that bicycle lane should be added instead of a traffic lane to reduce rush-hour traffic on Blue Highway. To support the assumption the author cites a fact that an additional traffic lane built on Green Highway increase the rush-hour traffic jams. The author also points out that many citizens of Shady Village are avid bicyclists and a questionnaire that 75 percent of respondents said they would like to spend much more time to ride a bike per week. Although this argument might seem reasonable at first glance, it is logically flawed in several respects.
In the first place, the author relies on an unfair analogy between Blue Highway and Green Highway. Actually, there is no evidence that the Blue Highway would have rush-hour traffic jams if it built an additional traffic lane like Green Highway did. It is quite possible that the condition on Green Highway is crucially different with one's on Blue Highway such as the road condition, the population, the environment and the weather, which cause the traffic jams on Green Highway. Beside, perhaps the traffic jams in winter of the Green Highway is a special case compared to other seasons, and sometimes, in winter people slow driving maybe one of the reasons to the rush-hour traffic jams. Without ruling out all these explanations, the author cannot conclude the argument hastily.
In addition, according to many avid bicyclists in Shady Village, the author suspects that adding a bicycle lane is a successful approach. However, the author cannot provide any evidence to support this assumption. We have no information about these bicyclists that if they will prefer ride on the Blue Highway. Furthermore, perhaps riding bikes are just their hobby for pleasure in free time rather than the transportation for rush-hour. If so, it will be nothing to do with the rush-time traffic jams. Since the author has failed to consider other possibilities, the argument is unconvincing.
Last but not the least, the author points out a result of a questionnaire that 75% percent of respondents would like to bicycle more hours per weeks than they currently do. Nevertheless, the author fails to provide the number and any other condition of the respondents that if they are representative in general. However, as a common sense, people who usually respond to this questionnaire would have more interest in bicycle. Besides, even if the result of the survey is reliable, there is no evidence that such more bicycle hours would be spent in rush hours. Unless eliminating these possibilities, the author cannot rely on the unbelievable questionnaire.
In sum, the author's argument mentioned above is unpersuasive. It is not based on a valid comparison between Green Highway and Blue highway and questionnaire, neither of which is dispensable for a conclusion argument. In order to draw a better conclusion and strengthen it, the author should have more information about the Blue Highway and Green Highway to have an effective comparison and reliable survey about the Shady Village and Bright City. |
