GMAT写作是GMAT考试中的一个重要组成部分，考生在备考阶段一定不要忽视GMAT写作的重要作用。接下来小编将结合具体的题目分析为大家带来GMAT分析性写作常见错误之弱类比，希望对大家的写作备考有帮助。
什么是弱类比错误
弱类比，即把毫不相关的两个事物拿来作比较，并由此得出一些结论。类比在GMAT写作ARGUMENT中的运用非常普遍，因为argument主要就是找一段文字中的逻辑错误，进行有理有据的驳斥。一般来说，类比包括三种情况，分别是：misapplied generalization(概括误用，即以大推小); hasty generalization(匆忙概括，即以小推大); faulty analogy(错误类比)。对于类比关系而言，它成立的前提和基础就是相似性，所以只要找到所比较两者间的差异性，那么再有逻辑的推理也是不成立的。
错误类比的英文表述：
错误类比(based on a false analogy )<横向>The argument rests on the assumption that A is analogous to B in all respects.
This assumption is weak, since although there are points of comparison between A and B, there is much dissimilarity as well.
For example, A..., however, B.... Thus, it is likely much more difficult for B to do....
常见错误之弱类比真题解析：
The following appeared in the editorial section of a local paper:
"Applications for advertising spots on KMTV, our local cable television channel, decreased last year. Meanwhile a neighboring town's local channel, KOOP, changed its focus to farming issues and reported an increase in advertising applications for the year. To increase applications for its advertisement spots, KMTV should focus its programming on farming issues as well."
Discuss how well reasoned ... etc.
翻译： 我们的有线电视台KMTV的广告时间的使用在去年下降了。而同时一个临近镇子的地方台KOOP把它的重点转向农业问题并在当年得到广告使用的增长。为了增加广告时段的使用，KMTV应该将其节目重心也转向农业问题。
逻辑分析：1. 错误类比，即使将重心转向农业确实是KOOP广告收入升高的原因，这一做法也未必能适用于KMTV。因为两个电视台有诸多的不同，这些不同可能导致这一措施在KMTV未必适用。比如KMTV的目标人群是城市居民，那么这一转变未必能够提升我们的收视率。只看到了它们表层的共性，而忽略了它们深层的差异，只看到了相似点，忽视了不同点。更多相关内容请点击》如何组织GMAT分析性写作。
参考范文：
In this editorial KMTV, a local cable television channel is urged to change its programming focus to farming issues in order to increase advertising revenues. The author’s line of reasoning is that KOOP’s change in focus was the cause of its increase in advertising and that since this tactic worked for KOOP it will work for KMTV as well. This line of reasoning is flawed in three important respects.
To begin with, the belief that the change in focus to farming issues was the cause of KOOP’s increase in advertising applications is unfounded. The only evidence offered to support this belief is that the change in focus preceded the increase in applications. Unfortunately, this evidence is insufficient to establish the causal claim in question. Consequently, it is possible that KOOP’s change in focus may not have been related to its increase in revenue in the manner required by the author’s argument.
In addition, the author assumes that the towns that KMTV and KOOP serve are sufficiently similar to warrant a conclusion based on an analogy between them. Even if we accept the view that KOOP’s change in programming focus to farming issues was responsible for its increase in advertising applications, differences between the towns could drastically alter the outcome for KMTV. For example, if KMTV serves a metropolitan area with little interest in agriculture, changing its programming focus to farming issues would most likely be disastrous. Lacking information about the towns KOOP and KMTV serve it is difficult to assess the author’s recommendation.
Finally, the author assumes that KMTV’s decrease in applications for advertising was due to its programming. However, since the author provides no evidence to support this assumption, it may be that the decrease was caused by other factors, such as recession in the local economy or transmission problems at the station. Without ruling out these and other possible causes the author cannot confidently conclude that KMTV’s programming was responsible for the decrease in advertising applications at hat station.
In conclusion, the author’s argument is unconvincing. To strengthen the argument the author would have to provide additional evidence for the claim that KOOP’s change in focus was responsible for its increase in advertising applications and that KMTV’s decrease in applications was due to its programming. Furthermore, it would be necessary to show that the towns that KOOP and KMTV serve are sufficiently similar to justify the analogy between them.
