GMAT邏輯套路總結(jié).

　　對(duì)于GMAT邏輯而言，題目是千千萬萬的，但是如果能夠找出GMAT邏輯套路的話，往往你就會(huì)發(fā)現(xiàn)GMAT邏輯題出題方式也是非常單調(diào)的，下面就來看看澳際小編為大家分享的GMAT邏輯套路總結(jié)，希望對(duì)大家有所幫助。文中觀點(diǎn)僅供參考。

　　這就是為什么要對(duì)邏輯題的題型和套路進(jìn)行分類的原因。下面我們用兩道削弱題讓大家體會(huì)一下什么叫GMAT邏輯題的套路。

　　The ice on the front windshield of the car had formed when moisture condensed during the night. The ice melted quickly after the car was warmed up the next morning because the drosting vent, which blows only on the front windshield, was turned on full force.

　　Which of the following, if true, most seriously jeopardizes the validity of the explanation for the speed with which the ice melted?

　　A. The side windows had no ice condensation on them.

　　B. Even though no attempt was made to drost the back window, the ice there melted at the same rate as did the ice on the front windshield.

　　C. The speed at which ice on a window melts increases as the temperature of the air blown on the window increases.

　　D. The warm air from the drosting vent for the front windshield cools rapidly as it dissipates throughout the rest of the car.

　　E. The drosting vent operates ficiently even when the heater, which blows warm air toward the feet or faces of the driver and passengers, is on.

　　這道題的推理精華是“冰融化得快是因?yàn)榭照{(diào)開最大”，按照我們解題的套路是先判斷它的假設(shè)，再進(jìn)行反對(duì)。對(duì)于這一類典型的“現(xiàn)象解釋型“文章，其假設(shè)的套路是“空調(diào)開最大是導(dǎo)致冰融化得快的唯一原因”，而我們要對(duì)此進(jìn)行反對(duì)，當(dāng)然是“空調(diào)開最大不是導(dǎo)致冰融化得快的唯一原因”或“還有其他原因?qū)е卤诨每臁?，我們可以把以上這句削弱的套路稱為特征甲。當(dāng)大家讀完這道題的選項(xiàng)后會(huì)發(fā)現(xiàn)，沒有與特征甲直接吻合的選項(xiàng)，但你會(huì)發(fā)現(xiàn)B選項(xiàng)其實(shí)表達(dá)的意思是一樣的。

　　我們?cè)賮眢w會(huì)一下這一道題：

　　A conservation group in the United States is trying to change the long-standing image of bats as frightening creatures. The group contends that bats are feared and persecuted solely because they are shy animals that are active only at night.

　　Which of the following, if true, would cast the most serious doubt on the accuracy of the group’s contention?

　　A. Bats are steadily losing natural roosting places such as caves and hollow trees and are thus turning to more developed areas for roosting.

　　B. Bats are the chi consumers of nocturnal insects and thus can help make their hunting territory more pleasant for humans.

　　C. Bats are regarded as frightening creatures not only in the United States but also in Europe, Africa, and South America.

　　D. Raccoons and owls are shy and active only at night; yet they are not generally feared and persecuted.

　　E. People know more about the behavior of other greatly feared animal species, such as lions, alligators, and snakes, than they do about the behavior of bats.

　　同樣是一篇典型的“現(xiàn)象解釋型”文章，其推理精華是“人們害怕并迫害蝙蝠僅僅因?yàn)樗鼈兪且归g活動(dòng)的害羞動(dòng)物”，而其假設(shè)的套路仍是“夜間活動(dòng)的害羞動(dòng)物是導(dǎo)致蝙蝠被人害怕并迫害的唯一原因”?，F(xiàn)在我們做的是削弱，看看能不能找到“夜間活動(dòng)的害羞動(dòng)物不是導(dǎo)致蝙蝠被人害怕并迫害的唯一原因”這個(gè)選項(xiàng)呢? 乍一看上去沒有完全吻合的，但仔細(xì)閱讀和思考各個(gè)選項(xiàng)后你會(huì)發(fā)現(xiàn)，D選項(xiàng)講的是不是也是一個(gè)道理呢?

　　通過這兩道題，我們能夠體會(huì)到，出題人在設(shè)計(jì)題目時(shí)，采用的GMAT邏輯套路是大同小異的，也可以叫做“換湯不換藥”。為什么有些題目難，很多考生做不出來、或者做不對(duì)呢?一個(gè)重要的因素還是在閱讀、提煉和發(fā)散這三點(diǎn)上。再者，由于訓(xùn)練太少，很多套路的感覺還沒有能夠在你腦中形成根深蒂固的條件反射，會(huì)造成很多模棱兩可的情形，這就是所謂的瓶頸，是需要不斷的總結(jié)和訓(xùn)練才能夠突破的。
