如何利用last试题备考GMAT逻辑：基础篇.

2017-08-11 作者： 201阅读

　　在GMAT逻辑的备考过程中，很多考生通过参考last考试的逻辑试题来提高GMAT逻辑的备考效率，其实这并不失为一个很好的GMAT逻辑备考捷径。那么考生在参考last试题的过程中需要注意哪些方面呢?下面就来分析一下。

　　所用复习材料

　　澳际出的两本“黄皮”，第一册上面有17套题，第二册上有11套题。这两本书在澳际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。)

　　澳际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 fective challenge to the author&aposs conclusion?)

　　△假设题(Which one of the following is an assumption on which the author&aposs 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&aposs reply?; Which one of the following principles, if valid, justifies the author&aposs 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&aposs & B&aposs 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&aposs 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&aposs 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&aposs 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&aposs argument is logically flawed in that it...; The source of the man&aposs 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&aposs 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&aposs 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&aposs argument by doing which one of the following?; Which one of the following techniques of argument does the author use in the passage?; A&aposs statement most closely conforms to which one of the following principles?; The relationship if A&aposs response to B&aposs argument is that A&aposs response...; A responds to B&aposs argument by...How is A&aposs response related to B&aposs 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。)

　　以上为大家简单介绍了如何通过last试题备考GMAT逻辑考试的相关要点和注意事项，考生可据此作为参考，熟练运用last试题的备考方法，有效提高GMAT逻辑的备考效率，从而在GMAT逻辑考试中发挥出更好的水平。 相关链接：
