3. Using your introduction, arrange the principle ideas concerning the subject into a vocabulary tree.
用你自己写的介绍整理出与此话题相关的主要概念，并制作一个单词树状图。

4. To create a vocabulary tree, put the subject at the center of a piece of paper.

围绕中心话题，划分出与主题相关的几个区域，比如：动词、描述性形容词、地点等等。

Tips:贴士

1. Remember that vocabulary goes from passive knowledge to active knowledge - this means that you need to repeat a word often before it becomes active vocabulary.
记住背单词都有一个从消极词汇到积极词汇的过程，即死记硬背到熟练掌握的过程，这就意味着要想熟练掌握一个单词，你要反复地记忆。

2. Be patient with yourself, it takes time for this process to work.
对自己有耐心，这个过程需要时间。

3. Try to always learn vocabulary in groups of words instead of random lists. In this manner, words are related to each other and are more likely to remembered over the long-term.
试着从词句间学习新单词，而不要对着词汇表学习。这样，学到的词汇就可以互相联系，也更能够长时记忆。
你要用到的只有：纸张、字典和笔。就是这么简单粗暴，还不行动起来吗？
