这里小编为大家推荐一种分析方法，帮助大家建立一种逻辑解题的模式和思维习惯。如果大家对于这种逻辑解题的模式比较熟悉之后，就能够一眼看穿题中蕴含的线索了。
一、GMAT逻辑链习题练习要求
1. 计时看问题和题干，一般在45s内。
2. 先不看选项、不看题干按自己的理解写出逻辑链。
3. 合理推测正确选项的可能方向(请发挥你丰富的想象力和推测力)
(详情请看 GMAT逻辑练习步骤 )
二、GMAT逻辑链习题练习模版
1. 计时：30s
2. 逻辑链Situation(刚开始练习先写好完整逻辑链，练习到逻辑链基本清晰的时候尝试尽量简化信息、提炼最精简的逻辑链)
1)完整模式：
Background Information: Life expectancy is the average age at death of the whole population.
Premise: Life expectancy in mid-nineteenth century North America was 40 years; now it is almost 80.
Conclusion: What we think of as the prime of life must have been considered old in that earlier era.
2)简化模式：
Life expectancy in earlier era was 40 years, but now is almost 80.
Thus, what we consider young must have been considered old in that earlier era.
3. 推测 (Prephrase: mentally formulate your answer to the question stem)
the average age at death is 40 years≠the usual length of life is around 40
some other reasons that lead to the outcome:极端值大, first-year infant mortality was extremely high in earlier era.
4. 选项分析：选*
选项解释不提供固定思路，请根据自己的理解对每一错误选项给出错误原因和类型的解释(无关选项思考清楚为什么无关)，对正确选项分析其与题干逻辑链的关系。

三、GMAT逻辑取非例题分析
例一：
Traditionally, decision-making by managers that is reasoned step-by-step has been considered preferable to intuitive decision-making. However, a recent study found that top managers used intuition significantly more than did most middle- or lower-level managers. This confirms the alternative view that intuition is actually more effective than careful, methodical reasoning.
The conclusion above is based on which of the following assumptions?
(A)Methodical, step-by-step reasoning is inappropriate for making many real-life management decisions.
(B) Top managers have the ability to use either intuitive reasoning or methodical, step-by-step reasoning in making decisions.
(C) The decisions made by middle- and lower-level managers can be made as easily by using methodical reasoning as by using intuitive reasoning.
(D) Top managers use intuitive reasoning in making the majority of their decisions.
(E) Top managers are more effective at decision-making than middle- or lower-level managers.
1、正确答案：E。
2、例题分析：
B: step by step decision-making is better than intuitive decision-making
P: top managers used intuition more than did most middle/lower-level managers
C: intuition is more effective than careful, methodical reasoning
In the argument it is show that while common people think that step by step decision-making is much effecter than intuitive decision-making, a study showed that top managers used intuitive decision more than the lower/ middle-level managers. Finally, the author said that the intuitive decision is much effecter than the careful, methodical reasoning.
As the situation that was showed above, how can the author assumed that the intuitive decision is effecter than the careful, methodical one? Who make the intuitive decision? In order to make this conclusion, we should assure whether the fact that the top managers’ decision is more effective.
例二：
Certain messenger molecules fight damage to the lungs from noxious air by telling the muscle cells encircling the lungs' airways to contract. This partially seals off the lungs. An asthma attack occurs when the messenger molecules are activated unnecessarily, in response to harmless things like pollen or household dust.
Which of the following, if true, points to the most serious flaw of a plan to develop a medication that would prevent asthma attacks by blocking receipt of any messages sent by the messenger molecules referred to above?
B：certain messenger molecules tells the muscle cells encircling the lungs’ airways to contract some damage
Asthma occurs then the molecules response to harmless things such as pollen or household dust, however the message was not necessary.
Method: block receipt of any message sent by the messenger molecules to prevent asthma attacks Weaken?
In the message some people plan to prevent asthma attacks by stop the messages which was sent by some messenger to the lungs that will cause the asthma. More ever, the molecules cannot distinguish whether the messenger was necessary.
What will lead if the messenger was stop? Some necessary messenger will not sent to the lung cell anymore, as a result it cannot encircle to contract the harmless factor, that will be bad.
(A) Researchers do not yet know how the body produces the messenger molecules that trigger asthma attacks.
(B) Researchers do not yet know what makes one person's messenger molecules more easily activated than another's.
(C) Such a medication would not become available for several years, because of long lead times in both development and manufacture.
(D) Such a medication would be unable to distinguish between messages triggered by pollen and household dust and messages triggered by noxious air.
(E) Such a medication would be a preventative only and would be unable to alleviate an asthma attack once it had started.
1、正确答案：C。
2、例题分析：
situation: 猴子常用m擦身子。
reason: m能分泌防蚊子的化学物质，而蚊子会传染猴子。
conclusion: 猴子常用m擦身子是为了防蚊子。
support: 在没有蚊子的季节， 猴子就很少用m擦身子。
