GMAT邏輯基本知識More About Arguments Components.

　　作為入門GMAT邏輯的基本知識，這是考生第一步要牢牢掌握的，不了解這些入門級知識量，后期無法很好地學(xué)會GMAT邏輯。下面就由澳際小編為大家講解GMAT邏輯基本知識第一課：More About Arguments Components。

　　Intermediate Conclusions

　　Sometime an argument has more than one conclusion. The following is an example:

　　Because Ming Li went to PekingUniversity, he is smart. Therore, he is likely to get a high score in GMAT.

　　The first thing you would notice is that there are two indicators in the above argument – because and therore. The former leads to a premise and the latter, a conclusion. Secondly, the first sentence is an argument by itself since it contains both a premise (Because Ming Li went to Peking University) and a conclusion (he is smart). Thirdly, the conclusion (he is smart) of the first argument is used to support the second sentence, which is the main conclusion. To put it another way, the clause “he is smart” is both a conclusion (in the 1st sentence) and a premise (in the overall argument.)

　　In CR tests, a dual-role clause like this is called an “intermediate” or “subsidiary” conclusion. It is not the main point of the overall argument, but it is still a conclusion.

　　Keep in mind that you have to find the main conclusion of an argument in CR test. Do not be fooled by an intermediate conclusion along the way. Use the “because” test if in doubt.

　　Background Information

　　Some CR questions are not pure arguments. They might also include background information, which, by dinition, helps you understand the flow of the argument, but does not contain a premise or a conclusion.

　　For example, an opinion of a critic or a committee is common in background information:

　　Editor: Many graduates from Peking University believe they can easily land a white-collar job after graduation. But they are wrong. A survey between 2000 and 2010 shows that more than 10% of Peking University Graduates during the last decade have no job offers within 6 months of their graduation.

　　The first sentence is neither a premise nor a conclusion. It is the opinion of “many graduates from Peking University.” The editor gives us this opinion to help us understand what he is trying to establish in his own conclusion (in the 2nd sentence) – that these graduates are wrong. In other words, he is arguing that a graduate from Peking University is NOT getting a job offer easily. The editor then buttresses his conclusion by citing a survey as the premise for his main conclusion.

　　A common pattern for such an argument is:

　　1) Opinion of someone else

　　2) The author’s conclusion (usually introduced with words such as but or however to highlight the contrast)

　　3) Premise(s) to support the author’s conclusion

　　As to examples of such opinions:

　　Many scholars believe that . . .

　　A few committee members argue that . . .

　　he dendant claimed that . . .

　　The classical theory holds that . . .

　　Hui’s recent research found that. . .

　　Most CDers voted [the posts by Zeros as their favorites]

　　All the above phrases telegraph to you that someone or some groups or some theories have such opinions or predictions. These phrases often end with the word that, but they do not have to. More often than not, they also start with some qualifiers, such as some, many, most, or all.

　　After the 1st sentence stating an opinion, the author is probably going to follow up with his or her own conclusion. And the author’s conclusion will usually contradict the opinion stated in the 1st sentence. Accordingly, we can call the 1st opinion “opposing viewpoint.”

　　僅僅掌握GMAT邏輯考試的入門知識是遠(yuǎn)遠(yuǎn)不夠的，但同時只有打好這入門的基礎(chǔ)，才有可能理解和戰(zhàn)勝GMAT邏輯考試的高難度，考生可根據(jù)澳際小編總結(jié)的GMAT邏輯基本知識來進(jìn)行基礎(chǔ)學(xué)習(xí)，祝每一位考友都能取得優(yōu)異的成績!
