GMAT邏輯題的解題小技巧
GMAT沒(méi)有GRE中的類比反義和填空,免去了背大量生僻單詞的負(fù)擔(dān),但增加了邏輯(critical reasoning)和語(yǔ)法改錯(cuò)(sentence correction).
其實(shí)過(guò)去的GRE也是有單項(xiàng)的邏輯題,但后來(lái)去除了,然后做為一種題型出現(xiàn)在了閱讀之中。
GMAT邏輯題是很有意思的,每做一道題,就像玩一個(gè)game。但真正面對(duì)考試,就不那么輕松,因?yàn)橛袝r(shí)間所限。尤其是難題,運(yùn)用嚴(yán)格的邏輯思維來(lái)做, 往往耗時(shí)甚多。尤其是五個(gè)選項(xiàng)逐一論證更是不切實(shí)際。所以對(duì)于GMAT邏輯題,我們必須要培養(yǎng)一種感覺(jué),依靠這種感覺(jué)我們可以很快地將一些無(wú)關(guān)項(xiàng)排除掉。 那這種感覺(jué)除了靠大量練習(xí)來(lái)培養(yǎng)外,更應(yīng)通過(guò)察覺(jué)選項(xiàng)中的“無(wú)關(guān)信息”,迅速做出判斷,將之排除。
這就是所謂“無(wú)關(guān)信息排除法”--- 通過(guò)選項(xiàng)中出現(xiàn)了與原文內(nèi)容和推理無(wú)關(guān)的內(nèi)容將之迅速排除。常常能排除五項(xiàng)中的三個(gè),再對(duì)剩下的選項(xiàng)認(rèn)真考慮,做出最后抉擇。
具體實(shí)踐兩道題
Teenagers are often priced out of the labor market by the government-mandated minimum-wage level because employers cannot afford to pay that much for extra help. Therefore, if Congress institutes a subminimum wage, a new lower legal wage for teenagers, the teenage unemployment rate, which has been rising since 1960, will no longer increase.
Which of the following statements, if true, would most weaken the argument above?
(A) Since 1960 the teenage unemployment rate has risen when the minimum wage has risen.
(B) Since 1960 the teenage unemployment rate has risen even when the minimum wage remained constant.
(C) Employers often hire extra help during holiday and warm weather seasons.
(D) The teenage unemployment rate rose more quickly in the 1970's than it did in the 1960's.
(E) The teenage unemployment rate has occasionally declined in the years since 1960.
先看完問(wèn)題,發(fā)現(xiàn)是削弱題;再讀原文,意思不難,很快提煉出其邏輯為如果國(guó)會(huì)制定更低的teenagers最低工資 ===》teenagers的失業(yè)率將不再上升。
顯然,正確選項(xiàng)首先要涉及最低工資和失業(yè)率之間的`關(guān)系,而其他內(nèi)容則為無(wú)關(guān)信息,可以排除。顯然A 和B都是相關(guān)的,而C在談季節(jié)問(wèn)題,D和E沒(méi)有涉及失業(yè)率快慢的原因,都與原文邏輯無(wú)關(guān),通通排除。
GMAT邏輯題,其實(shí)并沒(méi)有那么神秘莫測(cè)。只要考生摒棄急躁心態(tài),在平時(shí)的GMAT邏輯題復(fù)習(xí)的過(guò)程中,要花費(fèi)精力去培養(yǎng)自己的GMAT邏輯思維能力。具備邏輯思維能力,考生才能更好地分析GMAT邏輯題。不至于在GMAT邏輯題考查中,陷入無(wú)端的陷阱。
