就使用的角度而言，英文單字略可分成兩大類：認識類或被動類（recognition or passive vocabulary）與製造類或活用類(production or active vocabulary)。認識類的單字，顧名思義，僅停留於學習者的認知層面，無法實際應用於生活、職場或學術上；製造類的單字化被動為主動，學習者將其內化據為己有，隨時能在適合的情境派上用場。

依據教育部公佈的資訊，台灣學生在高中時期累積約 7 千個英文單字量，大學學測以 4 千個單字量為主，大學指考則要求高中畢業生應有的 7 千個單字。照理說，高中生進入大學時，基本的閱讀能力與生活上的溝通應無大礙，事實則不然。許多大學生書寫基本的電子書信(email)覺得困難重重，更遑論溝通與閱讀能力。究其主因，高中畢業時應具備的7千個單字量，許多是屬於「認識」單字，生活上用不著，所以無法加以活用。因此，本書編寫的初衷，主要是挑選目前大學生活情境中使用頻率最高，最可能派上用場的 2500個 單字，約佔高頻率(high-frequency)7 千 5 百個英文單字的三分之一，搭配學術領域的運用，重現這些「製造」單字的活用性，強化大學生在生活上與學術上必備的字彙能力。

學好英文，除了掌握文法，遣詞用字和句子結構外，增強字彙量絕對是第一要務。單字是學好英文的基本功，如同蓋大樓要先奠基一樣，好的基處是成功的保證。然而，聽起來很簡單的道理，卻因為學習內容不當，扼殺了許多年輕學子的英文夢。本書的出版主要在喚起學習者的記憶，將高中的7千個單字量轉換成最實用的2500單字，活用單字是掌握單字學習的第一步！冀望透過嚴格的過濾，學習者能在短時間內化書中全部的單字，使之成為生活上、校園裡的溝通利器。

當然，每個人因為不同的目的，對字彙量也有差別的需求，例如要閱讀《新聞周刊》（Newsweek）或《經濟學人》 (Economist) 等刊物，大約要有3-4萬個單字量，方能享受吸取知識的樂趣；如要閱讀大學英文教科書，因為專業術語的關係，至少要有2萬個單字量；要看懂一般雜誌或大眾小說大約需要1萬5千個單字。要學習的單字量多寡，取決於個人的需要，越專業，需要的單字量越多。然日常生活口語(spoken)或書寫(written)的溝通，只需具備本書的字彙量，就足以應付一般的溝通需求。

熟記單字至少需要兩項要訣：聽讀與句子脈絡。本書中的例句一來可輔助學習者理解單子的詞性與正確用法，二來可拓展學習者閱讀文本的廣度，符合所謂「置單字於句中脈絡學」(Learn a word in a context)的字彙學習策略；再者，藉由 MP3 中 native speaker的正確發音與單字音節，可刺激學習者腦中的記憶體，強化單字聯想(association) 的功能，達到事半功倍的成效。
