Argument 很少有人写呀!!
argument2
The following appeared in a letter sent by a committee of homeowners from the Deerhaven Acres to all homeowners in Deerhaven Acres.
"Seven years ago, homeowners in nearby Brookville community adopted a set of restrictions on how the community's yards should be landscaped and what colors the exteriors of homes should be painted. Since then, average property values have tripled in Brookville. In order to raise property values in Deerhaven Acres, we should adopt our own set of restrictions on landscaping and housepainting."
提纲:攻击点:
1。 类比错误,邻近的城市和我们城市。
2。 因果关系过于简单,不一定就是颜色布局的限制而导致的房价上涨。
3。 七年前,不一定就是将来一成不变的。
4。 这样的改变就只有颜色限制着一种解决方法。
In this letter, a committee of the Deerhaven Acres (DA) homeowners arrives at the conclusion that the owner of the DA should follow certain restriction of landscaping and house painting in order to enhance property values. In support of the prediction, the speaker claims that the average property values have tripled because they adopted the similar restrictions seven years ago. This argument rests on a serious of unsubstantiated assumptions, and is therefore unpersuasive as it stands.
To begin with, the first reason rests on the assumption that what has happened in nearby Brookvile (B) is analogous to what will happen in DA. This is weak; the author assumes that only relevant difference between B and DA is the location. If this were the case, the speaker's recommendation would be apt. However, there are many dissimilar as well, for examples, climate, population, custom and commercial. If all these conditions are all the same between B and DA, this could go a long way toward concluding the assumption mentioned above.
In the second place, no evidence has been offered to support the assumption that the reason the average property values tripled was the restriction while perhaps the restriction is important contributing factor to the average rise; it is not the only factor. Many other reasons such as the inside layout, scene, secure, preferential treatment and so on, could just likely account for the rise. Lacking a detailed analysis of the reasons the restriction succeeded, it would be foolish to attribute average property rise to the restriction.
In the third place, assuming that seven years ago, B community's average property values had tripled, and in the future while DA makes the same restriction, it will undoubtedly raise property values. People in DA might have entirely different tastes today, they hope to differ themselves from others, especially in house painting. Most of them want to buy the house that is allowed to design the colors of the exteriors by them. Lacking credible evidence that making restriction of colors would continue to attract people to buy the house, the speaker's recommendation cannot persuade me to adopt it.
Finally, even the restriction still can make profit in the future, there exist many other ways to solve this problem. DA can raise property values through special scene, secure system, preferential treatments and so on.
To sum up, the speaker fails to validate the conclusion that DA should adopt their own set of restrictions on landscaping and house painting in order to raise property values. The speaker should provide more evidence to solidify this argument. |
