词汇是表达思想、交流意见的根本。在日常生活中，丰富的词汇量可以让我们更准确、更生动地表达想法，使沟通更加流畅和有效。在各类英语考试中，词汇不仅是必考内容之一，也是提高阅读理解、听力理解和写作能力的基石，丰富的词汇量可以让学生在考试中更有信心，更好地应对各种题型。

在二十余年的英语专业教学过程中，编者发现学生在英语词汇学习方面存在不少问题。譬如，有的学生依赖阅读或听力来学习新单词，忽略了主动掌握和记忆词汇的必要性。他们往往没有制订词汇积累计划，词汇量增长缓慢。有的学生在刚学新词时会感到兴奋，但并不有效复习和巩固，遗忘或错用是大概率事件。也有的学生求;多不求;深平均用力，导致重要词汇掌握不牢，影响语言能力的整体提升。

基于以上种种，我们确定了本书的编写方案，旨在推出一部面向专四备考、符合科学记忆方法、顺应新一代大学生学习习惯的词汇书。
