《7天搞定托福单词（第二版）》在修订之后，对内容做了调整。全书分为大书和便携手册。
大书将所有托福真题文章的内容合并在一起进行词频统计。统计结束之后，无老师再将所有单词根据出现频率由高到低排列，使我们先背出现次数多的，保证了背诵的较高效率。为了提高新托福考试的单词在这本单词书中的排位，本书在统计之前就已经将新托福文章里的单词按照两次进行计算，保证考友们背的单词是最鲜活的单词。
大书里的单词是按照出现频率从高到低的次序排列的，因此极大地满足了不同考友的个性化需要。如果你需要考到100分以上，那么你就要把所有单词都背过，但是如果你仅需要考80分，那么你就可以不背出现频率为3次的单词，因为它们被考到的几率相对偏小。
在同一出现频率上，大书也是打破了传统的排列方法，采用由z～a的排列方式。这样可以防止在背诵时产生疲劳感。
附赠的小册子是著名的《镇魂单词包》，已经被广大托福考生实践过，可以在考场上起到胸有成竹，超水平发挥的神奇效果。
