实例解析SAT阅读逻辑题之类比

发布时间：2016-03-02 编辑：查字典英语网小编

　　SAT考试会在阅读题目当中设计一定的逻辑题来考察考生的基本的思维能力，据逻辑题考察统计（统计口径：OG8＋真题下册8套），逻辑题中的类比题型是14个，占有较大的比重，下面我们通过实例来进行分析。

　　逻辑题――类比

　　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 galaxys 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 as described in the passage?

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

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

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

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

　　 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。
