类比题的解答方法

　　SAT阅读中会涉及考生基本思维能力的考察，其中占有较大比重的就是类比题，关于类比题该如何解答呢?通过实际材料我们可加以分析。

　　类比题讲解：真题上册-OC题：

　　Black holes are the most efficient engines of destruction known to humanity. Their intense gravity is a one-way ticket to oblivion, and material spiraling into them can heat up to millions of degrees and glow brightly. Yet, they are not all-powerful. Even super massive black holes are minuscule by cosmic standards. They typically account for less that one percent of their galaxy’s mass. Accordingly, astronomers long assumed that super massive holes, let alone their smaller cousins, would have little effect beyond their immediate neighborhoods. So it has come as a surprise over the past decade that black hole activity is closely intertwined with star formation occurring farther out in the galaxy.

　　Q: Which of the following most resembles the relationship between “black hole activity” and “star formation” (lines11-12) as described in the passage?

　　(A) A volcanic eruption on one continent results in higher rainfall totals on another continent.

　　(B) Industrial emissions in one region lead to an increase an airborne pollutants in adjacent regions.

　　(C) A drought in a wilderness area causes a significant loss of vegetation in that area

　　(D) Decreased oil production in one country results in higher gas prices in oil-dependent countries.

　　(E) Overfishing in a gulf leads to an increase in the population of smaller aquatic organisms.

　　这道题的关键是找到题目中“类比的点”，当读者理解了题目所表现的关系时，就可以抽象出这个题目类比的点了，即“理论上不可能发生的实际却发生了”，然后通读选项，只有A符合这个类比的点，其他的选项都是“理论上可以发生，实际也发生”这么一点。

　　关于SAT类比题做题方法可以归纳成一下几点：

　　解题方法解析归纳1：SAT类比题选项特征：正确选项是定位句的改写：

　　1、词性的变换(动词变名词、形容词变副词等)

　　2、关键词可能不变(重要的名词)

　　3、语序的变换(因果、转折倒置;主动、被动变换)

　　题方法解析归纳2：SAT类比题错误选项的特点：

　　1、与原文主旨及分论点不一致

　　2、增加原文没有的新内容

　　3、定位点的主要内容有缺失或者错误。

　　4、程度和范围的改变

　　5、细节题中出现非本定位段落中的(即其他段落中的)细节。

　　6、定位段落的细枝末节(小列举结构)

　　7、极端词汇的出现

　　8、 原文中无明显比较，选项中出现比较词汇

　　以上就是给大家整理的类比题的解答方法，希望对大家有所帮助。
