在
笔记的记录我们可以分为两点来看，第一是通过框架去记录关键词。第二是通过细节去抓关键词。
首先，为什么我们要通过框架去记录关键词?其实托福听力尤其是TPO做的比较多，不难发现教授讲课的思路与我们写
主题信息: sea animals, underground water, navigate, dolphins
two types of sounds: vocalization—blowhole—student familiar
But today echolocation—air-fillded nasal sacs
我们通过对开头部分经常出现主旨题的规律将以下这些关键词记录下来，然后同样在做题过程中将题目的关键词也抽出来，然后去看与听力内容中的关键词是否有一一对应，如果有，这样的选项就是我们要找的正确选项。例如：
12. What is the lecture mainly about?
u Parts of the dolphin’s anatomy that allow it to navigate.
u Two different types of communication used by dolphins.
u The way that dolphins store air while swimming underwater.
u The meanings of different signals used by dolphins.
很显然，A选项anatomy对应的是记录的关键词blowhole与air-filled nasal sacs，navigate与记录的关键动词navigate或者有的学生记录find their way相对应，A选项的关键词与笔记中的关键词就是一一对应的，所以A是正确选项。而且关键词的标注也有利于我们排除错误选项，例如B选项不用多看，通过communication这个关键词就可以将B选项排除。以此类推CD选项也是可以通过这样一个关键词的抽取很快将其排除不会浪费太多时间。
阐述部分我们可以以典型的TPO17中第四个lecture讲octopus的内容为例。
论点：Incredible transformation in three ways: color, texture, size and shape
分论点1：Color：two kinds of cell –on skin surface Chromatophores
-below the Chromatophores: cells reflect light
分论点2：Texture: projection called papillae
分论点3：Size&Shape: muscular system, round stone, leaves
14. How does an octopus change color to match the colors in its envrionment? Click on 2 answers.
u By raising its papillae
u By releasing colored ink
u By reflecting light from its environment
u By contracting the muscles around its chromatophores.
15. What does the professor say about the function of the papillae?
u They produce dye in different colors.
u They propel the octopus through the water.
u They change the texture of the octopus’ skin.
u They help the octopus contract into a smaller shape.
16. What two examples does the professor mention to describe the octopus’ ability to change its shape? Click on 2 answers.
u A small round stone.
u The leaves of a plant.
u A cloud of ink.
u A piece of coral.
很显然，通过我们对论点及论点所对应的例子的记录，可以很容易将这三道题做出来，而且通过对题目和选项的关键词的抓取也很容易将这三点及论据挑出来。
所以，如果我们能够很好的在笔记过程中记录关键词，并且在做题过程中注意选项中的关键词和笔记所记录的关键词的一一对应，可以达到事半功倍的效果，快速并且准确地将题目做出来。当然前提条件就是我们需要提高我们的听力能力，这样才能够在听力过程中很好地抓住关键词并将其记录下来。
