GMAT考試主要考察學(xué)生的商科思維和邏輯分析能力，目標(biāo)管理題作為GMAT邏輯題中一種特殊的題型，是非常重要的。將結(jié)合具體案例為大家?guī)矸治?，關(guān)于如何提高這部分的正確率!

目標(biāo)管理題主要以2種形式出現(xiàn)：

1、增強(qiáng)題：幫助目標(biāo)達(dá)成

對于此類題型，在尋找正確答案時應(yīng)注意：

(1)提出新觀點(搭橋增強(qiáng))，說明goal能夠達(dá)到，或能更好地達(dá)到。

(2)排除其他plan成功的可能性(排他增強(qiáng))

(3)plan百利無害

2、削弱題：阻礙目標(biāo)達(dá)成

對于此類題型，在尋找正確答案時應(yīng)注意：

(1)其他的plan更有可能成功(他因削弱)

(2)實施plan不會達(dá)到預(yù)期的目的(結(jié)論有誤)

(3)plan有害無利

正確的解析思路

當(dāng)大家在面對這兩類題型時，如下：

1、確定題干目標(biāo)。一般需要看文章中“in order to/ to”后面的內(nèi)容是什么;

2、提取邏輯鏈。需要認(rèn)真讀取題干，對題干中提出的方案，進(jìn)行簡化，提取重要邏輯鏈信息;

3、判斷邏輯題型。即判斷此題目是增強(qiáng)還是削弱題型

下面我們一起來進(jìn)行例題解讀。

例題1：

Scientists are discussing ways to remove excess carbon dioxide from the atmosphere by increasing the amount that is absorbed by plant life. One plan to accomplish this is to establish giant floating seaweed farms in the oceans. When the seaweed plants die, they will be disposed of by being burned for fuel.

Which of the following, if true, would indicate the most serious weakness in the plan above?

(A) Some areas of ocean in the Southern Hemisphere do not contain

sufficient nutrients to support large seaweed farms.

(B) When a seaweed plant is burned, it releases an amount of carbon dioxide comparable to the amount it has absorbed in its lifetime.

(C) Even if seaweed farms prove effective, some people will be reluctant to switch to this new fuel.

(D) Each year about seven billion tons of carbon dioxide are released into the atmosphere but only about five billion tons are absorbed by plant life.

(E) Seaweed farms would make more money by farming seaweed to sell as nutritional supplements than by farming seaweed to sell as fuel.

解析1：

科學(xué)家討論增加植物吸收二氧化碳來減少過量二氧化碳。一個計劃是建立巨大的浮動海藻田。海藻死后，被作為燃料燒掉。

目標(biāo)：減少二氧化碳

計劃：建立浮動海藻田

邏輯鏈：浮動海藻田→吸收二氧化碳 削弱題，說明計劃達(dá)不到目標(biāo)。

(A) 南半球某些地區(qū)沒有充足的營養(yǎng)支持海藻田 (some 無意義概率，與邏輯鏈無關(guān)，錯誤)

(B) 海藻燒的時候，產(chǎn)生的二氧化碳和整個生命周期吸收的一樣多 (即沒有減少二氧化碳，削弱邏輯鏈，正確)

(C) 即使海藻田有效，一些人不愿換用這種新燃料 (some，無意義概率，無法判斷影響多大，錯誤)

(D) 每年大約70億噸二氧化碳被排入大氣，但只有50億噸被植物吸收了 (說明植物還是減少了二氧化碳，并不能削弱邏輯鏈，錯誤)

(E) 海藻田靠作為營養(yǎng)補充品比作為燃料更賺錢 (賺錢與邏輯鏈無關(guān)，錯誤)

例題2：

To entice customers away from competitors, Red Label supermarkets have begun offering discounts on home appliances to customers who spend $50 or more on any shopping trip to Red Label. Red Label executives claim that the discount program has been a huge success, since cash register receipts of $50 or more are up thirty percent since the beginning of the program.

Which of the following, if true, most seriously weakens the claim of the Red Label executives?

(A) Most people who switched to Red Label after the program began spend more than $50 each time they shop at Red Label.

(B) Most people whose average grocery bill is less than $50 would not be persuaded to spend more by any discount program.

(C) Most people who received discounts on home appliances through Red Label’s program will shop at Red Label after the program ends.

(D) Since the beginning of the discount program, most of the people who spend $50 or more at Red Label are people who have never before shopped there and whose average grocery bill has always been higher than $50.

(E) Almost all of the people who have begun spending $50 or more at Red Label since the discount program began are longtime customers who have increased the average amount of their shopping bills by making fewer trips.

解析2：

為了把顧客從競爭對手那里吸引過來，RL開始給消費滿50刀的人打折。經(jīng)理聲稱因為買超過50刀的單子增加了30%，所以計劃很成功。

目標(biāo)：從競爭對手那里吸引顧客

計劃：滿50刀就給打折

邏輯鏈：滿50刀就給打折→超過50的購物單子多了→計劃成功 削弱題，說明實際上計劃沒有成功。

(A) 大多數(shù)人在折扣項目開始后轉(zhuǎn)向RL，每次在RL購物時花費超過50美元。(反而增強(qiáng)了題干邏輯，錯誤)

(B) 大多數(shù)食品雜貨賬單低于50美元的人不會因為折扣計劃而花更多的錢 (但也沒說這些人會去competitors那里，與邏輯鏈無關(guān)，錯誤)

(C) 即使促銷結(jié)束大多數(shù)人還是會光顧RL (這還不成功嗎?增強(qiáng)了邏輯鏈，錯誤)

(D) 那些花了50刀以上的人是之前不來光顧的和經(jīng)常購買超過50刀的顧客 (還是把人吸引過來了，增強(qiáng)了邏輯鏈，正確)

(E) 自從打折計劃開始以來，幾乎所有在RL開始花費50美元或50美元以上的人都是長期顧客，他們通過減少旅行次數(shù)來增加購物賬單的平均數(shù)量(如果bill的增長來自于老顧客，且這些人會一次多買東西而降低光顧的次數(shù)，那就無助于收益增加，所以削弱了邏輯鏈，正確)

GMAT目標(biāo)管理題型，大家在做題的時候可根據(jù)以上做題思路完成平時的練習(xí)。祝大家早日殺G，獲得心儀學(xué)院的offer!
