主动词汇是指一个人所能掌握的词汇中能够在说话和写作中被自如运用的那部分单词。本书是奥尔森三本词汇系列书中的第二本，本书整体分为两大部分：一般词汇与学术词汇。本书的重点是锻炼读者熟悉语境记忆法并达到熟练运用语境记忆法！本书依然引入了一些杂志和报刊中的文章，介绍了一些互动交际中经常出现的一般用词，同时，作者也引入了一些SAT 、GRE等标准化考试中要考核的单词以及一些出版作品（例如，小说、教材）中较为学术化的词汇，一般用词用于让读者熟悉语境记忆法，学术用词用来增加读者的词汇库，既让读者学到了一种新型单词记忆法，又增加了读者的词汇量，一举两得！书中同样根据语境记忆法的使用原则开展了各色的专题活动（如，主题阅读、含义预测、自我测验、视觉单词、互动练习及话题讨论等），轻松有趣，层层递进，更好地锻炼了读者的自主单词记忆能力！
