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."

1．论断的前提是commuters认为blue高速公路一定要修正。然而作者并未提供出合适的理由。首先这些人都是什么工作，每天什么时候上下班没有说，有可能只是因为某一天时间长了就抱怨，作者应该进行全面而细致的调查，确定blue高速公路是否一定需要整治。

2．即使blue高速公路确实需要整治，也不能说明汽车道一定不好。作者引用G修建了一个机动车道，却没有缓解交通的压力，由此得出B修建此道也不会缓解压力，是没有道理的。作者没有给出G的情况，有可能G的情况比B严重许多，高速的大车多，经常出车祸等。多修一个车道是不足以缓解的，而对于B而言，多修一个就可以缓解。其次不排除绿高速新增车道设计不合理、路况差等因素，这样也不能证明开汽车道就不能解决问题。

3．也没有充足的理由说自行车道就一定好。虽然论者说S村的人热衷于骑车，但也许他们只是拿它当娱乐和运动，自行车并不是主流的交通工具，并不表示他们愿意骑车上班。而关于在当地做的的调查，论者没能提供资料证明被访者具有代表性，如果接受访问的都是坐公交车而没有车的人，或是距离近的人，那么这个前提就不会成立，。另外骑车的人受所候影响，如果遇到恶劣天气，人们是否还会骑车而不开车，这些都是不一定能保证的。 •

4．.作者没有考虑其他情况。另外解决交通堵塞还有赖于很多方面，如果设计不合理，路况不好，经常发生车祸，都无法保证论者的办法会很成功。

结论：论者要加强说服力，还必须进一步提供证据s的blue高速公路真的有问题，有关S村人是否愿意骑车上下班的资料，并对开设自行车道做周密的设计和管理。

1.False analogy. The traffic conditions of Green Highway might have been too poor before. One recent creation of a lane simple can't solve all the problem.

2.No evidence to show that people enjoy cycling to work. a)The distance between Shady Village and Bright City is long, and people might prefer to save energy for a whole day's work by driving. b) People have been complaining the commuting time's being doubled; if by bicycle, the time will be tripled, because the speed between the two means are of no comparison.
