1）l略读。
略读是为了了解一篇文章的中心思想而进行的快速阅读。
这种方法的目的是通过有重点的快速浏览把握文章的大意和重点。
了解文章的结构逻辑关系，问题的指向等，以利于迅速，准确地回答问题；
略读应注意以下几点：
（1）在浏览中不纠缠文章中无关主旨的细节，以保持阅读速度的连贯性。
把注意力集中于文章主题句的关键词语。
（2）以关键词语为重点快速浏览全文，理解中心思想，避免逐词逐句地索解意义。
关键词语主要有文章中的标题，引号部分，各种标示字体和划线部分；
表示因果，承接，转折等逻辑关系的过渡性词语，句中起支撑作用的名词，动词，形容词
2）寻读：
寻读是在快速阅读中有预定目的地寻找特定信息的一种方法，寻读的步骤如下：
第一研读问题，确定要寻找的信息，并预想它会以什么形式出现例如：
如果问题是事件的时间，就要注意日期；
如果问题是谁做了什么事情，就要留意人名。
第二步：
预计信息所在的位置。
第三步：
用“扫扫停停的”方式，目光迅速扫过字里行间直到有预定信息的字句，停下来仔细阅读。
第四步：
所有问题都有着落之后，不必读剩余部分。
