今天小編為大家?guī)?lái)GMAT備考邏輯題的眾多變化,，希望對(duì)大家GMAT備考有所幫助,，祝各位同學(xué)取得令人滿意的成績(jī)。和小編一起來(lái)看看吧,！
　　GMAT邏輯題,，題目?jī)?nèi)容雖然千變?nèi)f化，但其核心思想,，解題技巧卻從未發(fā)生改變,。做題時(shí)若沉溺于其光怪陸離的外表，而不思索邏輯題中的核心本質(zhì),，那便很難獲得一個(gè)好成績(jī),，往往勞神煩心而無(wú)所得。那么GMAT邏輯題真正能幫你取得高分的本質(zhì)思想是什么呢,，如何能如郭靖般以簡(jiǎn)單的十八招就打遍天下呢?在天道GMAT沖分班中我們所要深入探討的,，正是GMAT邏輯中那些一成不變，但卻從不過(guò)時(shí)的核心思想,。
　　僅以我們其中一節(jié)課所要講的內(nèi)容思維定式為例,，如近的考試中的一道真題：
　　一座城市分為東西兩部分，西邊交稅多,，東邊交稅少,，但是卻把大部分錢都投到了東邊，這樣做是不公平的,。如果說(shuō)得到的福利和繳的稅成正比,，才是公平的。問(wèn)這種說(shuō)法是基于那個(gè)假設(shè),。
　　選項(xiàng)：1.在決定錢給東邊還是給西邊時(shí),，主要考慮的是公平;
　　2.投的錢和該區(qū)域人民得到的福利成正比;
　　這道GMAT考試真題的出題點(diǎn)很明顯，在題目中所提供信息的不對(duì)等,，挑戰(zhàn)的是我們的思維定式,。投的錢多就代表當(dāng)?shù)厝嗣袼玫降母＠鄦?萬(wàn)一的錢都投在大樓建設(shè)上呢?我們不知道，而這樣的信息,，不屬于常識(shí),，屬于我們所想當(dāng)然的東西，但光靠我們相信他存在是不行的,，需要明確地表達(dá)出來(lái),，因此這題的答案應(yīng)該是第二個(gè)答案。這樣依據(jù)信息不對(duì)等原則挑戰(zhàn)我們思維定式的題目還有很多,，比如上過(guò)我們天道GMAT強(qiáng)化班的同學(xué)可能記得,，我們的邏輯分冊(cè)第52題是這么說(shuō)的：
　　A recent report determined that although only 3 percent of drivers on Maryland highways equipped their vehicles with radar detectors,33 percent of all vehicles ticketed for exceeding the speed limit were equipped with them. Clearly, drivers who equip their vehicles with radar detectors are more likely to exceed the speed limit regularly than are drivers who do not. The conclusion drawn above depends on which of the following assumptions?
　　A.Drivers who equip their vehicles with radar detectors are less likely to be ticketed for exceeding the speed limit than are drivers who do not.
　　B.Drivers who are ticketed for exceeding the speed limit are more likely to exceed the speed limit regularly than are drivers who are not ticketed.
　　C.The number of vehicles that were ticketed for exceeding the speed limit was greater than the number of vehicles that were equipped with radar detectors.
　　D.Many of the vehicles that were ticketed for exceeding the speed limit were ticketed more than once in the time period covered by the report.
　　E.Drivers on Maryland highways exceeded the speed limit more often than did drivers on other state highways not covered in the report.
　　雖然內(nèi)容和剛才的真題差距不小，一個(gè)說(shuō)福利,，一個(gè)說(shuō)超速,，但是兩道GMAT邏輯題所考察的點(diǎn)是一模一樣的,，你的思維定式告訴你那些經(jīng)常因超速被罰款的司機(jī)就是那些經(jīng)常超速的司機(jī)，可這是真的么?比如某些輕車熟路的司機(jī),，他們一天時(shí)間里可能有超過(guò)一半的時(shí)間在超速,，但因?yàn)樗麄兪熘本└鱾€(gè)點(diǎn)攝像頭和的分布，于是從未被罰款,。而我們誠(chéng)實(shí)善良的老師,，可能一天里就超了一次速，卻就被攝像頭拍到了,，被罰了款,，那到底誰(shuí)更容易被罰款呢?于是這并不一定對(duì)等的信息，需要我們?cè)谶x項(xiàng)中補(bǔ)上,。
　　這兩道題相對(duì)來(lái)說(shuō)要簡(jiǎn)單一些,，不對(duì)等的信息說(shuō)得比較直白，但有些時(shí)候這樣的隱含會(huì)非常的含蓄,，這時(shí)候也就要求同學(xué)需要有更為敏銳的思維,。比如有這一道題,，也是一道非常經(jīng)典的難題,，同學(xué)的正確率非常的低：
　　Often patients with ankle fractures that are stable, and thus do not require surgery, are given follow-up x-rays because their orthopedists are concerned about possibly having misjudged the stability of the fracture. When a number of follow-up x-rays were reviewed, however, all the fractures that had initially been judged stable were found to have heaLED correctly. Therefore, it is a waste of money to order follow-up x-rays of ankle fracture initially judged stable. Which of the following, if true, most strengthens the argument?
　　A.Doctors who are general practitioners rather than orthopedists are less likely than orthopedists to judge the stability of an ankle fracture correctly.
　　B.Many ankle injuries for which an initial x-ray is ordered are revealed by the x-ray not to involve any fracture of the ankle.
　　C.X-rays of patients of many different orthopedists working in several hospitals were reviewed.
　　D.The healing of ankle fractures that have been surgically repaired is always checked by means of a follow-up x-ray.
　　E . Orthopedists routinely order follow-up x-rays for fractures of bone other than ankle bones.
　　這題乍一看很多學(xué)生會(huì)一頭霧水，五個(gè)答案都不像正確答案,?？扇绻闶熘覀兩厦嫠岬降闹R(shí)的話，你就會(huì)意識(shí)到這其實(shí)還是你的思維定式在作祟,。文章的結(jié)論是后續(xù)的X光檢查是浪費(fèi)錢,，而原因是a number of follow-up x-rays were reviewed, however, all the fractures that had initially been judged stable were found to have healed correctly，問(wèn)題也就出在這個(gè)原因上,，誰(shuí)告訴你a number of follow-up x-rays 的檢驗(yàn)結(jié)果就是可信的,，亦或是有代表性的?如果這些follow-up x-rays 全部出自于同一個(gè)醫(yī)生之手，或者同一家醫(yī)院,，那是不是還有可能是這位醫(yī)生或者這家醫(yī)院的儀器有問(wèn)題呢?所以我們應(yīng)該選擇C選項(xiàng),，把數(shù)量和有代表性這兩個(gè)信息間的空缺補(bǔ)上。
　　當(dāng)然,，GMAT邏輯題還有其他的核心思想,，這些題所包含的邏輯思維核心往往也不止這一個(gè)，因此我們?cè)谡n上還將共同攻克隱含知識(shí),、差異比較,、數(shù)學(xué)思維等多道難關(guān)，讓你終真正達(dá)到化繁入簡(jiǎn),，以不變應(yīng)萬(wàn)變,，輕輕松松拿下GMAT邏輯題,。
