如果把文章（包括书面语和口语)比做高楼大厦，那么词汇就是整座大厦最基础的材料——砖和瓦。砖瓦的数量代表了大厦的规模，砖瓦的质量决定了大厦的命运。诚然，欲掌握一门外语，牢记大量词汇固然重要，但更重要的是掌握词汇的质量。换句话说，应先抓住语言中的基础词汇。本书收录了日语基础词汇近3000个。它们既有作者从多年教学实践中总结出的日语学习中的核心词，也有近期日本影视作品中出现频率较高的流行词。特别是着意加入了计算机网络用语，使本书更具时代感。本书把词汇分为基础用语、场景用语、专业用语三大类，每一类中又细分为若干小类别。考虑到读者使用方便，每个小类别的词语均按五十音图顺序排列。If we compare the articles (including written word and oral language) to high buildings and large mansions, the words are the foundations, namely, the bricks and tiles of the whole building. The quantity of bricks and tiles denotes the scale of the building and the quality of them determines the fate of it. Indeed that firmly memorizing a large number of words is very important to learn a foreign language, the quality of learning vocabulary is much more important. In other words, the basic vocabulary in a language should be firstly grasped. This book collects almost 3,000 Japanese basic words ranging from the core words summarized in the teaching practice for years of the author to the popular words frequently appearing in the latest Japanese films and TV programs. Moreover, the cyber words especially added in make the book keep abreast with the new trend.The vocabulary in this book is categorized into three categories including basic words, situational words and technical terms and each category is subdivided into several subclasses. For the convenience of readers, the words under each subclass are sorted by ordering of syllabary.
