Argument9: 【越洋农场战队作业】
The following appeared in a memorandum from a dean at Omega University.
“Fifteen years ago, Omega University implemented a new procedure that encouraged students to evaluate the teaching effectiveness of all their professors. Since that time, Omega professors have begun to assign higher grades in their classes, and overall student grade averages at Omega University have risen by thirty percent. Potential employers apparently believe the grades at Omega are inflated; this would explain why Omega graduates have not been as successful at getting jobs as have graduates from nearby Alpha University. To enable its graduates to secure better jobs, Omega University should now terminate student evaluation of professors.
1. 因果关系。new procedure 与分数上升之间没有必然的因果关系。可能试卷出题简单了,或者学生的能力与过去相比确实提升不少。
2. 片面性,分数提升百分之三十,咋一看还挺吓人,但是它并没有提供是否现在的评分系统与过去是否有不同,也许过去用的是gpa制,现在用的是百分制,或单科提升到800分,比如GRE。
3. 关于就业,认为A大学的就业比O大学好是因为分数问题,这也是不太合理的。可能由于O大学的学生能力确实不如A强,又或者由于专业问题,O大学所设置的某些专业找不到对口的职业等等。

In this memorandum, the dean at Omega University (OU) asserts that only to terminate student evaluation of professors, can graduates get better jobs. To support/substantiate the recommendation, several evidences are employed as follow: (1) Introducing a policy of student evaluation of professors leads to a great rising of grades; (2) Compared to 15 years ago, the student average grades increased by thirty percent; (3) Because of the inflated grades, graduates from OU could not get better job as Alpha University (AU). Close scrutiny of this evidences reveal that they lend little credible support to the dean’s recommendation. 列举1,2,3的做法不太好吧?显得只是简单的列举,没深度的样子To begin with, the author’s line of reasoning is that the introduction of evaluation system was the cause of the great rising of average grades. However, while it may establish a correlation between the two events, and also indicate a correlation, though less significantly, between the two, it does not establish a general causal relationship. To establish this relationship, other factors that can bring about this result must be considered and eliminated. 前面这部分有点长吧?我觉得简化一下,然后多举反例比较有说服力吧For example, it is entirely possible that the examinations now adopted by OU are much easier than those 15 years ago. And it is also probable that the abilities of students in OU are actually upgraded. Without ruling out these factors attribute to the result, the author cannot rely on this limited evidence to bolster his claim.
Second, the author assumes that the reason students from OU cannot get better opportunities for job than students from AU is the apparent inflated grades. However, there is no evidence linking (linking?)the two events, thus leaving open the possibility the two events are not causally related but merely correlated. There may be other possibilities as most students in OU, who majored in those subjects not so popular, are much more than social needs. To the contrary, students from AU majored in those subjects are badly need by the society. Another probability may be that abilities of students from AU are really much better than those of OU students. Lacking of compelling evidence to support the causal connection between these tow events, the author’s recommendation is not worthy of consideration.
Finally, the argument lies in an assumption that the thirty percent different in grades indicates that professors gave higher evaluations to the students in behalf of themselves. However, the author provided no evidence to support this assumption. If fifteen years ago, OU adopted a 100-point grade system and few years later, it turned to an 800-point grade system as GRE, the thirty percent difference in grades only lead to a opposite result. Without more information about its grade system, the author’s recommendation amounts to poor advice.
In sum, the evidences provided by the author lend little credible support to his recommendation. To better evaluate the author’s suggestion, we would need more information about how difficult are the examinations taken by students at OU in recent 15 years, and those subjects set by OU. Moreover, the detailed information about the grade system employed by OU also will be appreciated
写得很好的,只是错误之间的逻辑关系还可以在改进下Argument2: 【越洋农场战队作业】
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 restrictions on landscaping and housepainting.”
1. 因果错误,post hoc, ergo propter hoc, B地采取一系列措施使,然后地产价格上涨,只是时间上的先后关系,无因果关系。
2. 时间已经是7年前,现在很多情况都发生了变化,不能忽略时间上的差距。
3. B地与D地简单的等同关系。就算把B地的措施引入D地,也不一定行得通。

In the letter, the committee of homeowners in Deerhaven Acres (D) recommends that a series of restrictions on the appearance of homes should be adopted with the purpose of raising property values. To bolster this recommendation, similar polices of Brookville (B), which was implemented in the seven years since and lead to a tripled average property value in B. At the first glance, the argument appears to be somehow plausible, but further reflection reveals that it is guilty of/suffers from several logic fallacies.
To start off, this argument has engaged in “post hoc, ergo propter hoc” reasoning. The mere fact that the introduction of restrictions on the appearances of the house seven years ago preceded the tripled average property value in B is insufficient to establish a cause-and-effect relationship between these two events. Many other factors may attribute to the same results. For instance, it is entirely possible that a big manufactory was built there also 7 years ago, then many workers from others places were settled there, which would probably result in raising the property values. Without ruling out these possible scenarios, it would be sheer folly to establish a causal relationship between the two events. (renders the conclusion based upon it highly suspect. ) 举例论证有点少了
In the second place, the argument assumes that the conditions including the economic status, consumption ratio, government polices, remain have remained unchanged in B since the contrast is between the conditions seven years ago and now. It is entirely possible that, during these years, there is a great inflation in B. Compared to seven years ago, the property values is really tripled. However, commodities that ten dollars can buy now might be only equal to two dollars can seven years before. In the fact, the economy growth and the tripled property values only amount to foams. Lacking information about conditions mentioned above, the recommendation cannot be taken seriously. 举例少了,还有很多因素呀,人们观念的变化也是挺好的原因
Even assuming that the implemented restrictions attribute to the rising property values in B, the committee fails to consider possible differences between B and D that might help to bring about a different result for D. An apt illustration lies in that potential D homebuyers might have different appetite for home’s exterior appearance than homebuyer in B. Blindly introducing these restrictions in D, it is only to find that property values in D decline. There may be also other differences, such as locations, design, and community management, etc. As it stands, the committee’s solution to the problem is based upon an oversimplified analysis of the issue. 这段原因挺多的,不错
In conclusion, this recommendation of introducing restrictions similar with those in B is ill-conceived and logically flawed. To lend more credible support to the suggestion, clear evidence that the implementation of B’s restrictions must be put forward, and those factors otherwise attribute to the rising of property values should be eliminated. Moreover, if there are evidences that can substantiate house markets in D and B share a common ground, the recommendation may be more convincing.
还是一样的问题,整体写得很好的,我觉得每个错误多举几个可能性比较好,只举一个反例会觉得不充分 |
