解釋題,，又稱explain題目,。通常需要對GMAT邏輯題目的某一個部分做出合理解釋。就是選出正確選項(xiàng)能夠解釋文章中給出的現(xiàn)象或者矛盾,。解釋題在GMAT邏輯題目中考察的比例有所增加,，其重要性日漸凸顯,，同學(xué)們應(yīng)該給予足夠的耐心。
　　標(biāo)志性詞語：explain,、reason,、account for.本文就把GMAT邏輯解釋題解題思路給大家介紹下，希望提高大家的GMAT邏輯推理能力,。
　　一,、GMAT邏輯解釋題的答案形式
　　Explain/Solve the Discrepancy及填空題解題原則：定義結(jié)論句之因果關(guān)系，并確認(rèn)議題焦點(diǎn),。
　　1,、題目中有矛盾現(xiàn)象者：通常有轉(zhuǎn)折字眼(極少數(shù)情況中無轉(zhuǎn)折字，但句意上仍可找出矛盾處),。
　　1)找出矛盾句后出現(xiàn)的因果關(guān)系(因果之間會有矛盾),。
　　2)定義因--->預(yù)期果(預(yù)期結(jié)論通常與題目中的結(jié)果是相反狀況)。
　　正確答案：否定預(yù)期果,。
　　錯誤答案：削弱了答案,。
　　2、題目中無矛盾現(xiàn)象者：視為Assumption類型來做,。
　　1)題目中可辨識因果關(guān)系(結(jié)論句)者,，找否定Weaken的答案。
　　2)題目中有跳躍結(jié)果者,，找找補(bǔ)缺口的答案,。
　　3、找出題目--->結(jié)論--->答案間可連結(jié)的關(guān)系,。
　　4)題目--->結(jié)論間出現(xiàn)的新元素,，要在答案中可找到。
　　3,、Some Tips：Explain題中若無矛盾現(xiàn)象,，較多為填補(bǔ)缺口類型。
　　二,、GMAT邏輯解釋題解題技巧：
　　1,、找出A, however B,將however看作therefore,解釋時思考整體
　　2、解釋的對象是兩者比較：正確選項(xiàng)必須體現(xiàn)此相對量
　　3,、解釋的對象再說上升下降,，正確選項(xiàng)必須體現(xiàn)變化
　　三、GMAT邏輯解釋題真題解析
　　例題：OG13-P5010-6 Parland's alligator population has been declining in recent years, primarily because of hunting. Alligators prey heavily on a species of freshwater fish that is highly valued as food by Parlanders, who had hoped that the decline in the alligator population would lead to an increase in the numbers of these fish available for human consumption. Yet the population of this fish species has also declined, even though the annual number caught for human consumption has not increased. Which of the following, if true, most helps to explain the decline in the population of the fish species?
　　(A) The decline in the alligator population has meant that fishers can work in some parts of lakes and rivers that were formerly too dangerous.
　　(B) Over the last few years, Parland's commercial fishing enterprises have increased the number of fishing boats they use.
　　(C) The main predator of these fish is another species of fish on which alligators also prey.
　　(D) Many Parlanders who hunt alligators do so because of the high market price of alligator skins, not because of the threat alligators pose to the fish population.
　　(E) In several neighboring countries through which Parland's rivers also flow, alligators are at risk of extinction as a result of extensive hunting.
　　解析：題目：P地鱷魚數(shù)量近幾年一直在下降,，主要由于對鱷魚的獵殺,。而鱷魚喜歡捕食的淡水魚是P地居民所喜愛的食物，那么P地居民就希望鱷魚數(shù)量的減少能帶來淡水魚數(shù)量上升這個結(jié)果,。但是淡水魚數(shù)量也減少了,，還是在當(dāng)?shù)鼐用駴]有增加淡水魚消費(fèi)量的情況下,。
　　題干：解釋魚群數(shù)量下降這個現(xiàn)象。
　　A選項(xiàng)說鱷魚數(shù)量下降會使得漁民可以在之前危險的地方進(jìn)行作業(yè),，題目中已經(jīng)排除了人為因素對魚群數(shù)量的影響,，不能忽視或者否定原文給定的信息。
　　B選項(xiàng)說P地的漁業(yè)企業(yè)增加了捕魚船的數(shù)量,，跟A選項(xiàng)問題一樣,。
　　C選項(xiàng)說鱷魚不僅僅吃淡水魚，同時也吃另一種喜歡捕食淡水魚的物種,，那么鱷魚數(shù)量減少，這里所說的另一種喜歡捕食淡水魚的物種數(shù)量會上升,，能夠?qū)е碌~數(shù)量下降這個結(jié)果,。正確!
　　D選項(xiàng)討論為什么要捕殺鱷魚，與題目論點(diǎn)無關(guān),。
　　E選項(xiàng)說鄰國鱷魚瀕臨滅絕,，None of our business…
