[转帖]Lsat逻辑单题捷进大法
★★作者：gmatcracker (andycheer) ★★
★★电邮：gmatcracker@2... ★★
前言
本捷进大法旨在为备考GMAT而苦于对其逻辑题(CR)十分怵头的考友排忧解难。
LSAT考试由四个SECTION组成，一个阅读理解，一个逻辑组题，剩下两个是逻辑单
题。本捷进大法主要讨论通过练习CRACK LSAT逻辑单题而达到CRACK GMAT逻辑题目
的的理论、方法、步骤、操作实例、注意事项等。
本来在下在复习GMAT时，对LSAT是很不屑一顾的（这样说也不对，应该叫很不以为然
吧），不过那天有个MM拿LSAT题让我帮她看看，硬着头皮做了两套，大概100道单
题，突然发现自己对老米的逻辑思路有了更深一层的认识。再拿出GMAT笔试真题以前
做错的题，发现自己以前错得“莫名其妙（十分愚蠢）”，而不少费费从答案倒推和
自己牵强附会的“解释”也是狗P不是。于是开始猛攻LSAT逻辑单题，颇有收获。总结
了一些东西，希望对大家有用。
有的大虾说LSAT逻辑要做上N遍才能有效果，我的经验则不然。在我看来，做一道题你
就赚一道题，这也是我写这篇东西的原因。考友们不妨有时间多作，没时间少做，能
做尽量做。至于LSAT是不是破解GMAT的九阴真经、葵花宝典，我就不敢打保票了。在
使用本捷进大法的过程中，如有任何疑问或对本贴有任何意见、建议，请发电邮至

大家共同探讨。
所用复习材料
新东方出的两本“黄皮”，第一册上面有17套题，第二册上有11套题。这两本书在新
东方各教室门口小贩那里可以买得到，叫价一般是50-60块，讲讲价或几个人合买可以
便宜到40块或更少。黄皮的字迹不大清楚，看着费劲，如觉得有必要可结合新乐敦或
润舒眼药水或高倍放大镜使用。
（如买不到黄皮可用其替代品，如宇航出版社出的LSAT书，上有15套题，不过我不知
道是哪15套；也可与胜奇门联系订购其光盘版，没见过，大概是用黄皮扫描后存成PDF
格式的吧。）
新东方出的陈向东编的厚厚的《GRE GMAT LSAT逻辑推理》，里头有“精选”的80道
LSAT逻辑单题，并附有翻译和解释。（此书非必选项，有了黄皮可以不用买。）
LSAT逻辑题型与GMAT逻辑的异同
LSAT逻辑题型及典型问法：
△加强题(Which one of the following statements, if added as a premise
to the argument, would make the conclusion valid / strengthen the
argument?; Which one of the following, if true, would make the
conclusion in the passage a logical conclusion?; Which one of the
following is an additional piece of information that would support
the conclusion?)
△削弱题(Which one of the following statements, if true, most clearly
undermines / seriously weaken the conclusion / argument?; Which one
of the following assertions, if true, provides the most effective
challenge to the author’s conclusion?)
△假设题(Which one of the following is an assumption on which the
author’s argument relies?; Which one of the following most
accurately states a hidden assumption that the author must make in
order to advance the argument above?; Which one of the following is a
presupposition essential to the reasoning in the passage above?)
△评价题(Which one of the following is the most accurate evaluation
of the author’s reply?; Which one of the following principles, if
valid, justifies the author’s argument?; Which one of the following
would it be most helpful to know in order to evaluate the argument?)
△解释题(The author concludes that ... partly because...; Which one
of the following, if true, argues most strongly against the
explanation reported in the passage?; Which one of the following, if
true, most helps to explain why ...?; Which one of the following
principles, if established, would justify the judgments about A’s &
B’s actions?)
△矛盾解决题（也可归类到解释题里）(Which one of the following, if true,
most helps to resolve the apparent discrepancy between the two?;
Which one of the following, if true, most helps explain the
difference in...?; Which one of the following, if true, most helps to
reconcile the author’s decision with the goal stated in the
passage?)
△结论（归纳）题(It can be concluded from the statements above
that...; Which one of the following statements most accurately
expresses the author’s main point?; Which one of the following
statements CANNOT be true?; Which one of the following inferences can
be most reliably drawn from the passage above?; The passage as a
whole is structured to lead to which one of the following
conclusions?; Which one of the following is the best statement of the
primary point of the passage?; Each of the following can be inferred
from his argument EXCEPT...; Which one of the following claims is
central to the author’s argument?; If the statements above are true,
then which one of the following must also be true?)
△句子完成（划线填空）题(Which one of the following is the best
completion of the argument above?; Based on the passage above, which
phrase does NOT provide a logical completion to the following
sentence?)
△信息支持（反向加强）题(Which one of the following is most strongly
supported by the information above?; The statement above, if true,
most strongly support which one of the following claim?)
△推理缺陷题(What is the flaw in the reasoning above?; The author’s
argument is logically flawed in that it...; The source of the man’s
erroneous reasoning is his...; The reasoning in the argument is most
vulnerable to the criticism that it...; )
△逻辑相似性题(Which one of the following is most similar in logic to
the argument above?; Which one of the following exhibits the same
logical flaw as that exhibited above?; Which one of the following
could be best supported by the same type of reasoning as that
exhibited in the passage?; Which one of the following contains the
error of reasoning described by the author in the passage?; Which one
of the following most closely parallels the flawed pattern of
reasoning in the author’s reply?)
△逻辑相悖题(In which one of the following situations is the
principle expressed most clearly violated?)
△两人争论内容题(The source of A & B’s dispute is their lack of
agreement on which one of the following terms?; Which one of the
following is the point at issue between A & B?)
△逻辑策略方法题(Which one of the following is the best line of causal
analysis for A to do?; The author establishes his position in the
passage by doing which one of the following?; The author of the
passage argues by...;The argument seeks to do which one of the
following?; A most seriously weakens B’s argument by doing which one
of the following?; Which one of the following techniques of argument
does the author use in the passage?; A’s statement most closely
conforms to which one of the following principles?; The relationship
if A’s response to B’s argument is that A’s response...; A responds
to B’s argument by...How is A’s response related to B’s argument?)
（注：有些问法可以归为不止一类；一些较冷僻的问法没有列在括号里，但应该不会
影响判断。）
从以上题型可以看出，LSAT前几种题型和GMAT是完全一样的，这类题要么难度和GMAT
不相上下，要么在阅读难度和逻辑绕圈子上难一些，是较之GMAT更上一层楼的题。
后几种涉及到逻辑推理的具体方法，GMAT中没涉及到，但其实后几种才是LSAT的精
华，才是真正提高逻辑水平的训练，才是LSAT借以CRACK GMAT的法宝，所以是不能略
去不做的。
GMAT逻辑有“句子作用题”，LSAT中没涉及到，但基本上靠费费给的方法就能搞定，
有阅读能力作后盾这种题更是小菜。(通过练习逻辑策略方法题，做句子作用题的能力
可以得到很大的提高。) |
