下面，我将再用GRE/GMAT的作文填空法来帮大家强化“魔板”的方法以及填空的概念。

　　其实跟新托福一样，GRE/GMAT中作文也分为两个部分：“一休”和“阿狗”。那么这两个部分也是同等重要，而且一个难以短期突破，一个只能短期突破，所以“魔板”的作用就在这里显示出来了。“阿狗”由于是驳论文，不需要发表考生自己的观点，只需要考生指出段落的逻辑错误即可，那么专门用来写驳论文的反驳式段落就显得非常重要，而我们大家都没有学过如何去写驳论文，所以可以说不背“魔板”基本就不可能及格。而背“魔板”也分高手和水手，所以我个人认为有以下三重境界：

　　·知道如何提炼“魔板”

　　·知道需要将提炼的“魔板”排列组合成自己的考试“魔板”

　　·知道怎么往“魔板”里正确、恰当地填空

　　只有达到这三重境界的全部才可能获得满分。下面我将以几个例子来巩固“魔板”的提炼方法以及重点介绍如何填空，而排列组合由于非常简单而且因人而异，这里就不再介绍，有问题可以发邮件跟我交流。

　　1. 开头段

　　In this argument, the arguer concludes that sending the mechanics of GAA to a two-week QCS on proper maintenance procedures will automatically lead to improved maintenance and to greater customer satisfaction along with greater profits for the airline. To support the conclusion, the arguer points out that the performance of the maintenance crews in the automobile racing industry improved markedly after their crews had attended the seminar. In addition, the arguer reasons that since the maintenance crews of the automobile racing industry and the mechanics of GAA perform many of the same functions, the airlines will gain similar benefits from the training program. This argument suffers from several critical fallacies.

　　In this argument, the arguer recommends that C should advise its citizens to install both air conditioners and fans for cooling in order to reduce the cost of electricity. To justify this claim, the arguer provides the evidence that many citizens of C suffer from the rising costs of electricity. In addition, he cites the result of a recent study that using fans alone costs more than using air conditioners alone, and that using both fans and air conditioners costs less than either using fans or air conditioners alone. A careful examination of this argument would reveal how groundless the conclusion is.

　　In this analysis, the arguer claims that P University should offer employment to the spouse of each new faculty member that they hire. To substantiate the conclusion, the arguer cites the example of B College where professors prefer to have their spouse employed in the same geographical area. In addition, the arguer assumes that this offer of possible job for their spouse on the campus, no matter whether it will be accepted, is the only factor that new professors consider in deciding whether to accept a university position. This argument is unconvincing for several critical flaws.

　　In this argument, the arguer advocates that the C Corporation should hire DF, a family owned local company that offers varied menu of fish and poultry, instead of GT Company, the present supplier of food in C’s employee cafeteria. The recommendation is based on the observation that the GT is expensive, that its prices have kept rising, that it does not serve special diets, and that three employees complained about it. Meanwhile, the arguer assumes D to be a better choice for C because a sample lunch of this company that the arguer happened to taste was delicious. This argument is problematic for two reasons.

　　The conclusion in this argument is that F College can expect to increase enrollment by promising to find jobs for students after graduation. In support of this prediction, the arguer claims that college-bound students are increasingly concerned about job prospects after graduation. Moreover, the arguer assumes that this attempt has three benefits: (1) to enable F to compete with more famous schools; (2) to encourage students to start career preparation early; (3) to encourage students to complete their coursework. This argument is fraught with vague, oversimplified and unwarranted assumptions.

　　2. 中间段

　　First, the argument is based on a false analogy. The arguer simply assumes that airplane mechanics and automobile maintenance crews perform many similar functions, but he does not provide any evidence that their functions are indeed comparable. As we know, the structure, operation and function of airplanes and those of automobiles differ conspicuously. It is true that both the airplane and the automobile need refueling and engine maintenance, but even here there exist fundamental differences: the structure and the building materials of each other’s engines are different, so is the oil they use. Therefore, even though the two-week Quality-Care Seminar proved effective in improving the performance of the maintenance crews in the automobile racing industry, there is no guarantee that it will work just as well for airplane mechanics

　　Second, the arguer commits a fallacy of hasty generalization. Even if the maintenance of the airline has been improved as a result of sending its mechanics to the Seminar, which is, of course , unwarranted assumption, it does not follow that there will be greater profits as well as greater customer satisfaction for airline. As we know, customer satisfaction depends on several major factors other than good maintenance of the airplane. For instance, customers are generally concerned about the punctuality, the on-board service, the ticket price, the luggage handling procedure and even the discount, all of which are ignored by the arguer. Besides, the arguer does not provide any solid information concerning how the airplane can improve its profits. Unless Get-Away Airlines can significantly increase its customers or passengers and at the same time cut down its costs, both of which are unknown from this argument, there is no guarantee that it will “inevitably” harvest greater profits. Actually, the arguer’s recommendation of investing in this training program a the only way to increase customer satisfaction an profits would most probably turn out to be ineffective and misleading.

　　In the first place, the arguer fails to take into account the geographical factors in the analysis. While we informed that there are wide geographical differences in the nation of Claria, and that many citizens are experiencing rising costs of electricity, the arguer fails to make clear the exact number of those citizens or their percentage in the national population, as well as the geographical distribution of these citizens. If only a small portion of the whole population are experiencing the rising costs of electricity while most familiars do not have similar experience, then the reason might be that the former do not use electricity sparingly. In this case, the rising costs of those families have nothing to do with what kind of electric appliance they use to cool their house. Or if only families living in hot areas are spending more money on cooling, then it is unwise to require citizens living in temperate and frigid zones to install both fans and air conditioners, in the absence of all this information, it is impossible for us to install both fans and air conditioners. In the absence of all this information, it is impossible for us to evaluate the recommended policy that is intended to help every household nationwide to reduce their electricity cost.

　　In the second place , the comparison in this argument is incomplete and selective, the arguer discovers that using fans alone is more cost effective than using air conditions alone, and that using both fans and air conditioners are the least expensive way of cooling. However, the arguer fails to provide any information regarding the actual amount of time for using, respectively, fans alone, air conditioners alone, and both fans and air conditioners in those three groups of surveyed families. It is very likely that these three groups of families are located in three very different climatic regions of Claria, and hence the amount of days of the year during which they need to cool their houses varies significantly. Families living in cooler areas of the nation certainly cool their houses for fewer hours and hence use less electricity than families living in hot areas, no matter what cooling appliance they use. Unless we are certain that the surveyed families ling in the same climatic region, or that they need to cool their houses for the same amount of hours in the same year although they live in different regions, which is very unlikely, we have every reason to doubt the trustworthiness of this comparative study. Furthermore on electricity may be using more electricity for purposes other than cooling. Unless the arguer also takes this factor into consideration, the comparison is unconvincing.

　　First of all, the argument is based on a hasty generalization. According to the cited studies, professors at Bronston College are happier living in small towns when their spouses are also employed in the local area than when their spouses work in distant areas, which is understandable. This fact tells very little about what actual conditions the professors often consider as important when they choose where to work. Even if we accept the arguer’s assumption that whether their spouse can find a job in the local area Is the only important question that new professors consider when they decide whether to accept is it likely that the professor will consider accepting the university’s offer. Consequently, it is unwarranted to assume that new professors will accept Pierce’s offer whether their spouse can find satisfactory employment in the local area.

　　In addition, the arguer fails to consider several other relevant factors that may influence professors’ decision. For instance, since Pierce’s location is not ideal, the pay it offers should be high enough to be attractive. New gifted professors are also concerned about the position they can have and the courses they supposed to teach in the new university. What’s more, what researchers care most about might be the university’s research conditions such as laboratory equipments, adequate research funds, etc.

　　Finally, the arguer hints that the morale of Pierce’s entire staff is low, but he fails to analyze the causes. Is it because the management of the university is poor, or because the pay is too low, or because the local area stuffers from economic depression, or because the local environment is severely damaged by industrial pollution? Under these circumstances, offering employment to the spouse would be ineffective at all for the purpose of attracting more new professors. Furthermore, if these problems do exist, even if Pierce succeeds in hiring many of the most gifted teachers and researchers of the country, the general moral of the whole faculty would remain low.

　　The major problem with this argument is that the arguer fails to convince us that Cedar’s present supplier the Good-Taste should be fired. First, the fact that the Good-Taste is the second most expensive caterer in the city may be due to its better foods, quality service and high reputation in this industry. Second, the fact that it prices have been rising for the last three years may be due to nationwide inflation or the rising cost in the food industry. Third, the fact that Good- Taste refuses to serve special diets does not indicate that it cannot meet the needs of Cedar Corporation unless the arguer can demonstrate that Good-Taste served special diets at first and now it refuses to do so hence disappointing Cedar’s employees complained, which makes it impossible for us to e valuate the overall service of Good-Taste. Maybe these three people are those few on special diets. Even if they have every reason to complain about the foods or service of the supplier on a certain day, these three people’s opinion lacks the necessary representativeness based on which we can make any general judgment concerning the overall performance of Good-Taste.

　　Another point worth considering is the arguer’s hasty generalization. We are informed that Discount serves fish and poultry, but we do not know whether Cedar’s employee all prefer this limited menu. We can believe that one sample lunch that the arguer happened to taste was indeed delicious, but based on this slim information, we can never evaluate the overall performance of Discount.

　　One major assumption in short of legitimacy is the causal relationship claimed between college-bound students’ increasing concern abut job prospects after graduation and their expectation on the university to find jobs for them. Students’ increasing concern about job prospects may mean that when they choose which university to go to they prefer those universities that can offer the majors most likely to lead to more job opportunities and higher income after graduation. They may also be more interested in prestigious universities because their students are more competitive and more welcomed in the job market. As is known to everyone, in a market economy, promising to find jobs for students is impractical and hence rather doubtful. This strategy may prove misleading and counterproductive in the end. Instead of promising jobs to students, Foley College should devote its resources and efforts to offering more majors with good job prospects as well as attracting more prestigious professors to enhance its reputation.

　　In addition, the conclusion is based on a gratuitous assumption that promising students jobs will make students more conscious in their study. This, however, is unwarranted. When students do not have to worry about their employment after graduation, they feel no pressure in their study; as a result, they will become more passive and dependent and gradually lose the initiative to improve themselves. Although it is more likely that they will complete their coursework, but when they graduate, no company would like to employ them. By then the university’s promise will turn not to be meaningless.

　　3. 结尾段

　　In summary, the conclusion reached in this argument is in valid and misleading. To make the argument more convincing, the arguer would have to prove that college-bound students are most concerned about the promise of jobs after graduation and the F College can keep its promise in the end. Moreover, I would suspend my judgment about the credibility of the recommendation until the arguer can provide concrete evidence that promising students jobs can actually encourage them to work harder in their study. Otherwise, the arguer is simply begging the question throughout the argument.

　　To conclude, the argument is not persuasive as it stands. Before we accept the conclusion, the arguer must present more facts that GT has indeed to meet the requirements of C Corporation. To solidify the argument, the arguer would have to produce more evidence concerning the foods and service of D and how they can better meet the needs of C’s employees.

　　As it stands, the argument is not well reasoned. To make it logically acceptable, the arguer would have to demonstrate that an offer of employment to the spouse is the only condition that new professors consider on accepting P’s offer. Additionally, the arguer must provide evidence to rule out other possible causes of the low staff morale at the university.

　　To sum up, the conclusion lacks credibility because the evidence cited in the analysis does not lend strong support to what the arguer maintains. To strengthen the argument the arguer would have to provide more evidence concerning the percentage of the affected families and their geographical distribution. To better evaluate the argument, we would need more information regarding the electric expense relevant to the actual amount of time for cooling among, respectively, the three groups of households and the amount of electricity used for other purposes in all three groups of families under survey.

　　In conclusion, the arguer fails to establish a causal relationship between sending Get-Away’s mechanics to the Quality-Care Seminar and improved maintenance, greater customer satisfaction and greater profits for the airline. To strengthen the argument, the argument, the arguer would have to provide evidence that automobile maintenance and airplane maintenance are similar in every aspect. To better evaluate the argument, we would need more information about the relationship between improved maintenance and greater customer satisfaction along with greater profits.
