词的难度个人感觉和GRE红宝书差不多，不过没有红宝书里那么多单词。作者说大约1000个单词，分成25个单元，介绍200个词根。
　　书是按照词根来分类的，可是使用的感觉是，比中国人自己写的词根词典等要容易记背一些，因为讲解详尽，而且因为是英语的缘故，语感很容易出来，而不像其他背法，记住之后不会使用。
　　书中每单元除了介绍好几个词根及其组成的词汇之外，还介绍来自传说和神化里的词。比如，Stentorian,Stoic这些。每两个词根也就是八个词之后有一个小练习，每单元有一个大一点点的练习。
个人觉得，本书适合那些有一段时间背单词的人，他们想背一个单词之后真正记住它，并且会使用它。要是急着考试背单词，就还是算了，因为需要的时间比较长。另外，水平估计是超过了托福一点的.iso 文件。需要虚拟光驱软件。
