一、GMAT逻辑加强题的答案特点

1.让结论成立，提高结论成立的可能性，表达与结论类似的观点。具体的类别有：

A.加强措施

① 目的能更好达到。具体的思考方法：a.把选项和措施结合起来看;b.思考措施如何达到目的。

② 若文章是两个措施作对比。则正确答案形式是：别的措施不好。

③ 文中提及措施有无坏处。则正确答案形式是：加强没有坏处。

B.加强事实找原因

① 举例子说明原因找对了(即举否命题的例子)。

② 举例子来直接支持or解释原因。

C.加强普通推理

① 若问题中加强conclusion。则正确答案形式是：优先考虑举例子直接说conclusion成立。

② 若问题中加强argument。则正确答案形式是：放在原因&结论中间，提高结论成立可能性。

(做加法：选一个与原因平行的答案来加强结论)

2.事实加强比道理加强好，道理加强比假定加强好——当选择区分度较小时用这个原则。

二、GMAT逻辑错误答案的特点

1. 相反答案(即削弱)
2. 伪装答案——答案加强了一个与原文结论相似的结论
3. 无关答案

三、GMAT逻辑加强题的解题技巧：

1.找出原文中的结论

2.锁定结论，几乎所有正确答案都对结论有影响

3.原文中有推理漏洞，需要仔细寻找加以支持

4.预先判断正确选项特征范围

GMAT逻辑 加强题真题解析

The neuroscientist’s statements, if true, most strongly support which of the following conclusions?

B.Perfectly recalling every detail of all their past experiences could help at least some animals react more appropriately than they otherwise would to new situations they encounter.

C.Generalizing from past experiences requires clear memories of most if not all the details of those experiences.

D.Recalling every detail of all past experiences would be incompatible with any ability to generalize from those experiences.

E.Animals can often react more appropriately than they otherwise would to situations they encounter if they draw on generalizations from past experiences of similar situations.

Situation A neuroscientist claims that memory evolved to help animals learn how to react appropriately by generalizing from past experiences but that this does not require animals to remember all details of those experiences.

Reasoning What conclusion would the neuroscientist’s theory about memory most strongly support? The neuroscientist asserts that the evolutionary function of memory is to help animals learn to react appropriately by drawing on generalizations from similar experiences they have had. If memory is to serve this function, drawing on generalizations must actually help animals learn to react more appropriately than they otherwise would, even when they do not remember all the details of past experiences.

A Even if no animal ever recalls all the details of any past experience, animals could still learn through generalizations, as the neuroscientist claims.

B This statement could be false even if all of what the neuroscientist says is true. Even if it were never helpful for any animal to recall every detail of all its past experiences, animals could still benefit by learning through generalizations.

C Generalizations from experiences might be made while the experiences are occurring, so that only the generalizations and not the details need to be remembered.

D The neuroscientist only claims that remembering perfect details is not required for memory to serve its function, not that such perfect recall is incompatible with memory serving its function.

E If the evolutionary function of memory is to help animals react more appropriately by drawing on generalizations from past experiences, it follows that animal memories can often successfully serve this function in this manner.

Correct Answer： E.
