　　大家在GMAT邏輯復(fù)習(xí)過程中對需要對比的GMAT邏輯選項(xiàng)往往會(huì)無所適從，為此澳際小編特收集整理GMAT邏輯錯(cuò)誤選項(xiàng)特征分享給大家，希望對大家有所幫助，文中觀點(diǎn)僅供參考。

　　GMAT邏輯錯(cuò)誤選項(xiàng)特征一、 訴諸權(quán)威/大眾信念/人身攻擊/感情色彩等選項(xiàng)(非學(xué)者態(tài)度)

　　GMAT邏輯錯(cuò)誤選項(xiàng)特征二、 反對前提的選項(xiàng)

　　GMAT邏輯錯(cuò)誤選項(xiàng)特征三、 涉及兩比較對象的選項(xiàng)

　　1. 比較雙方應(yīng)與題目比較雙方一致(1。2。兩點(diǎn)偶的觀點(diǎn)和原文相反～～是我理解錯(cuò)了還是原文打錯(cuò)了啊?～～)

　　2. 比較的概念要與原文完全等同(涉及與原文無關(guān)的新概念的比較必錯(cuò))

　　OG2. The average life expectancy for the United States population as a whole is 73.9 years, but children born in Hawaii will live an average of 77 years, and those born in Louisiana, 71.7 years. If a newlywed couple from Louisiana were to begin their family in Hawaii, therore, [ their children would be expected to live longer than would be the case if the family remained in Louisiana. ]

　　Which of the following, if true, would most seriously weaken the conclusion drawn in the passage?

　　A. Insurance company statisticians do not believe that moving to Hawaii will significantly lengthen the average Louisiana’s life. (一、訴諸權(quán)威)

　　B. The governor of Louisiana has falsely alleged that statistics for his state are inaccurate. (二、反對前提)

　　C. The longevity ascribed to Hawaii’s current population is attributable mostly to genetically determined factors.

　　D. Thirty percent of all Louisiana’s can expect to live longer than 77 years. (三1、比較雙方應(yīng)與題目的一致。應(yīng)為Hawaii VS. Louisiana，而非30%Louisiana VS the other 70%)

　　E. Most of the Hawaiian Islands have levels of air pollution well below the national average for the United States. (三2、比較概念應(yīng)與題目的一致。應(yīng)為 Life expectancy，而非 Pollution level)

　　3. 原并列內(nèi)容變成比較，必錯(cuò)

　　OG33. Rural households have more purchasing power than do urban or suburban households at the same income level, [since some of the income urban and suburban households use for food and shelter can be used by rural households for other needs.]

　　Which of the following inferences is best supported by the statement made above?

　　A. The average rural household includes more people than does the average urban or suburban household.

　　B. Rural households have lower food and housing costs than do either urban or suburban households.

　　GMAT邏輯錯(cuò)誤選項(xiàng)特征四、 可能對，也可能不對的選項(xiàng)

　　GMAT邏輯錯(cuò)誤選項(xiàng)特征五、 非提問要求的選項(xiàng)

　　5. A program instituted in a particular state allows parents to prepay their children’s future

　　college tuition at current rates. The program then pays the tuition annually for the child at any of the state’s public colleges in which the child enrolls. [Parents should participate in the program as a means of decreasing the cost for their children’s college education.]

　　B. The amount of money accumulated by putting the prepayment funds in an interest-bearing account today will be greater than the total cost of tuition for any of the public colleges when the child enrolls.

　　C. The annual cost of tuition at the state’s public colleges is expected to increase at a faster rate than the annual increase in the cost of living. (五、題目問削弱，選項(xiàng)是加強(qiáng))

　　D. Some of the state’s public colleges are contemplating large increases in tuition next year.(五、題目問削弱，選項(xiàng)是加強(qiáng))

　　E. The prepayment plan would not cover the cost of room and board at any of the state’s public colleges.

　　OG44. Some people have questioned the judge’s objectivity in cases of sex discrimination against women. But the record shows that in sixty percent of such cases, the judge has decided in favor of the women.

　　(后面的這些原文沒寫例子，偶一下子也找不出，但都不難理解，等找到了再往上面補(bǔ)充吧～～)

　　GMAT邏輯錯(cuò)誤選項(xiàng)特征七、 百分比和實(shí)際數(shù)量

　　GMAT邏輯錯(cuò)誤選項(xiàng)特征八、 部分和整體

　　GMAT邏輯錯(cuò)誤選項(xiàng)特征九、 相關(guān)性和因果性

　　GMAT邏輯錯(cuò)誤選項(xiàng)特征十、 代表性問題 (Survey等的樣本)

　　GMAT邏輯錯(cuò)誤選項(xiàng)特征十一、 必要性和充分性(Necessity & Causaion)

　　GMAT邏輯錯(cuò)誤選項(xiàng)特征十二、 含if, unless, as long as 等連詞的選項(xiàng)，在歸納題中可能正確(是選項(xiàng)的前提必然成立);在演繹題中必錯(cuò)(給出無關(guān)前提)

　　以上就是GMAT邏輯錯(cuò)誤選項(xiàng)的全部內(nèi)容，考生朋友在遇到類似的選項(xiàng)時(shí)一定要多留個(gè)心眼，自己辨別，最后祝大家都能考出好成績。
