# 李平武单词解密套装新版（共2本） ## 《英语词根与单词的说文解字》+《英语词缀与英语派生词》 --- 【One-Line Pitch】 A classic two-volume Chinese reference set that systematically demystifies English vocabulary through root-and-affix analysis, treating Latin and Greek roots as the "radicals" of English—ideal for serious learners, teachers, and self-studiers who want to move beyond rote memorization to principled word-building. --- 【Book Arc】 - **Opening (~0%–9%)**: The author's prefaces trace the book's 1984 origins and its "说文解字" (character-etymology) inspiration, positioning English roots as analogous to Chinese radicals. The core question—"What is a root?"—is answered by reviewing definitions from Chesterfield, Quirk, and lexicography, culminating in the **morpheme-based theory** that grounds the entire book: words are built from free and bound morphemes, with roots as the primary carriers of lexical meaning. - **Early (~9%–28%)**: The book establishes the **etymological landscape**—statistics show classical (Latin/Greek) sources account for roughly 56% of English vocabulary, rising to 70%+ by dictionary count. A close reading of the U.S. Constitution's preamble demonstrates that classical-root words are the "difficult" words learners stumble on. This section then defines **bound roots** (vis, manu, lect) and introduces the crucial distinction between **derivational affixes** (combine with free roots) and **primitive affixes** (combine only with bound roots), with dozens of the most common primitive prefixes and suffixes catalogued with examples. - **Middle (~28%–47%)**: The theoretical framework expands into a **three-level derivation system**: zero-level derivation (no affix—simple words, compounds, conversions), first-level derivation (bound root + primitive affix → primary derivatives), and second-level derivation (free root + derivational affix → ordinary derivatives). This unified model absorbs traditional word-formation methods (conversion, compounding, derivation) into one coherent system. The book then turns to **form**: root syllable counts (80%+ are monosyllabic), vowel/consonant patterns, and the four types of spelling changes at morpheme boundaries—letter addition (doubling, linking vowels, silent -e), letter loss, letter change (assimilation, ablaut, y→i), and hyphenation rules. - **Late (~47%–53%+)**: The focus shifts to **sound and stress**: the principle "roots are stressed, affixes are light" is demonstrated across native, borrowed, and primitive affix categories. The excerpts show how stress placement follows root position, with examples like con·'sist, 'vis·ible, and 'child·hood. This bridges into the practical payoff—being able to predict pronunciation and stress patterns from morphological analysis. - **Ending (beyond excerpts)**: The full set continues with 120 most-common roots analyzed in depth (Part 2), 330 additional roots with example words (Part 3), exercises with answers, and a companion volume on affixes covering 400+ items. The excerpts do not cover these detailed root entries, but the framework established in the opening sections is designed to make those reference sections usable. --- 【Key Takeaways】 - **Morpheme theory is the foundation** (Early): The book's core claim is that all English words are built from morphemes—the smallest sound-meaning units. Free morphemes (friend, white) stand alone; bound morphemes (vis, -ible, un-) must combine. This atomic view explains word structure more thoroughly than word-based grammar, just as atomic theory surpasses molecular theory. - **Classical roots are the high-yield target** (Early): Latin and Greek sources account for 56–70%+ of English vocabulary, and these are precisely the "hard words" learners struggle with. The good news: only a few hundred roots generate tens of thousands of words. Master a few hundred roots, and you unlock the classical layer of English. - **Primitive affixes are the hidden key** (Early): Beyond familiar derivational affixes (un-, -er, -ly), there exists a class of **primitive affixes** (ex-, con-, -ible, -ion) that only attach to bound roots. These are the "imported parts" that came with Latin/Greek loanwords—and they are the real learning challenge because they never appear in ordinary affix lists. - **Three-level derivation unifies all word-formation** (Middle): The book's most elegant contribution: zero-level derivation (no affix: act→act, man+power→manpower), first-level (bound root + primitive affix: ex-+pend→expend), and second-level (free root + derivational affix: friend+ly→friendly). This single framework absorbs conversion, compounding, and derivation into one analyzable system. - **Root form predicts word form** (Middle): Four types of spelling changes occur at morpheme boundaries—letter addition (runner, helicopter's -o-, include's silent -e), letter loss (writer, transpire), letter change (affect from ad+fect, decision from decide+ion), and hyphenation (co-operation, pro-British). Recognizing these patterns turns "irregular" spellings into predictable rules. - **Stress follows the root** (Late): The principle "词根重读，词缀轻读" (roots stressed, affixes light) holds across native, borrowed, and primitive affix types. Knowing where the root sits tells you where the stress falls—a powerful tool for both pronunciation and word recognition. - **Roots are like Chinese radicals** (Opening): The author's founding analogy—English roots function like 偏旁部首 in Chinese characters—makes the system intuitive for Chinese learners. Just as 解 decomposes into 刀+牛+角, invisible decomposes into in-+vis+-ible, and vis then organizes a whole family of related words. --- 【Reading Tips】 - **Skim the prefaces** (~0–6%): They explain the book's origin and philosophy but contain no technical content. Read the 初版前言 for the charming "说文解字" analogy, then move quickly to Part 1. - **Deep-read the theory chapters** (~9–28%): The distinction between free/bound morphemes, derivational/primitive affixes, and the three-level derivation system is the intellectual core. Don't skip the U.S. Constitution analysis—it's a concrete demonstration of why classical roots matter. Take notes on the primitive affix lists; they're the book's most reusable reference material. - **Use the form-change chapter as a reference** (~44–47%): The four types of spelling changes (addition, loss, change, hyphenation) are rule-based but dense. Read for the patterns, then return when you encounter puzzling spellings in real vocabulary study. - **Watch for cross-references to the companion volume**: The root book repeatedly points to 《英语词缀与英语派生词》 for detailed affix treatment. If you own both, read them together—the affix book fills in what the root book deliberately leaves out. - **Skip or skim the statistical/etymological sections** (~16–19%) if you're a practical learner: The percentages and historical background are interesting but not essential for using the root system. The actionable content is in the definitions, classifications,
