【特别提示】在英语语言历史演变的过程中，单词的词形和词义都会发生或多或少的变化，但是“万变不离其中”。这个“中”就是某一单词的“核心含义”。词根、词缀是构成英语单词的元素，了解、牢记和把握这些元素，不仅可以牢固地掌握单词的意义，达到事半功倍的学习效果。对于应试的读者，词根在篇章中所起到的一致性和连贯性的作用更是非同小可的。本词根表中，出现的词汇仅仅为考试大纲词汇表要求的词汇，但是如果掌握好这些词根，也同样为将来的学习打下了坚实的基础。
【符号说明】最前面部分为词根，词根有两种：自由词根(例如“act”<做>，可以单独构成词汇)和附着词根(例如“-ag-”<做>，不可单独用作词汇)。单词后带“*”为超纲词汇。
