Academic Vocabulary — AWL 与学术语域
本质 AWL(Academic Word List) 570 个词族覆盖学术文本约 10% 词汇——是 IELTS Reading / Writing / Listening lecture 的"通用底座"。但单纯背单词没用——必须学到 collocation / register / nuance 三层:会用、用得自然、用得对场合。中国考生最常踩的坑是: ① 背了 AWL 但写作还在用 "make / do / get" 等小词;② 用 AWL 但搭配错误("do research"应是"conduct research");③ 用 AWL 但 register 不对(学术写作里 "kids" 是 informal,应用 "children")。词汇分的差距不在词汇量,在词汇深度。本页围绕"AWL 10 个 sublist + collocation 学习法 + register 差异 + nominalization + 学术 vs 口语词汇对照 + 5 大反模式"展开。
学习目标
读完本页后,你应该能够:
- 通览 AWL Sublist 1-10 的高频词(每 sublist 60 词,分 10 周覆盖)
- 区分近义词的 register 差别("investigate" 比 "look at" 学术 / "enhance" 比 "make better" 高级)
- 用每个词的 4 种形态(noun / verb / adj / adv)
- 学会 5 种 nominalization("decide → decision", "react → reaction")让句子学术化
- 避免学术写作里 informal 词("a lot" / "kids" / "stuff")
- 用 collocation 字典学 verb-noun / adj-noun 自然搭配
1. AWL 体系结构
AWL 10 个 sublist 按词频递减排列——Sublist 1 是最高频的 60 词族,Sublist 10 是最低频的 30 词族。优先掌握 Sublist 1-3(180 词族,覆盖 75% AWL 出现率)。
| Sublist | 词族数 | 累计覆盖率 | 例词 |
|---|---|---|---|
| 1 | 60 | 30% | analyse, approach, area, assess, available |
| 2 | 60 | 50% | achieve, acquire, administrate, affect, appropriate |
| 3 | 60 | 65% | alternative, circumstance, comment, compensate |
| 4 | 60 | 75% | access, adequate, annual, apparent, approximate |
| 5 | 60 | 82% | academic, adjust, alter, amend, aware |
| 6 | 60 | 87% | abstract, accurate, acknowledge, aggregate |
| 7 | 60 | 91% | adapt, adult, advocate, aid, channel |
| 8 | 60 | 95% | abandon, accompany, accumulate, ambiguous |
| 9 | 60 | 98% | adjacent, albeit, assemble, collapse |
| 10 | 30 | 100% | adjacent, albeit, panel, pose, reluctance |
1.1 学习节奏建议
60 词 / 周 是经验上最优速率——慢于此进度迟缓,快于此记不牢。配合 每天 5-10 分钟 SRS 复习 循环,2-3 个月可掌握 Sublist 1-3,基本覆盖 75% AWL 高频用法。
2. 词汇深度的 4 个层次
记一个词有 4 个层次的深度 —— 大多数中国考生卡在 Level 1-2,这是为什么"背了很多词但用不上"的根本原因。
2.1 L4 例:"investigate" vs "look at"
字典两者都译"调查 / 看",但 register 完全不同:
| 词 | Register | 例句 |
|---|---|---|
| investigate | Academic / formal | "The study investigated the impact of..." |
| look at | Informal / spoken | "Let's look at this question." |
学术写作用 "investigate",口语用 "look at"。用错就显得别扭——学术写作里 "Let's look at..." 立刻让考官降级。
2.2 L4 例:"big" vs "substantial" vs "significant"
字典三者都译"大",但 nuance 完全不同——big 中性、substantial 量大且实质、significant 重要且统计意义。9 分要求看到上下文能精准切换。
| 词 | Register / nuance | 例句 |
|---|---|---|
| big | 通用 | a big problem(中性) |
| substantial | 量大 + 实质 | substantial increase(数量大,有实质性) |
| significant | 重要 + 统计 | significant difference(统计显著 / 重要的) |
| considerable | 量大 + 中性 | considerable effort |
写作里 "big problem" 偏口语,学术写作用 "substantial / significant / considerable"。
3. Collocation 学习法
Collocation 是词汇 9 分的核心——不是知道单词意思,是知道与哪些词搭配自然。中国考生写"have a research"是字典对的,但 native 永远说"conduct research / undertake research"。
3.1 高频 verb + noun
verb + noun 是最容易暴露 non-native 的搭配类型——下面 10 组覆盖学术写作里最高频被错用的搭配。
| 中式 | Native |
|---|---|
| make a decision | 也对,但用 reach a decision / arrive at a decision 更地道 |
| do research | conduct research / undertake research / carry out research |
| make attention | draw / direct / pay attention |
| say an opinion | express / voice / hold an opinion |
| make a discussion | hold / have a discussion |
| make a decision | reach / arrive at / come to a decision |
| get a conclusion | draw / reach a conclusion |
| make experiments | conduct experiments |
| make a contribution | make / offer a contribution(make 这条对) |
| make influence | exert / exercise influence / have influence |
3.2 高频 adj + noun
adj + noun 搭配决定形容词的精准度——big/good/bad 是基础词,9 分卷需要换成 substantial/compelling/adverse 等学术替代。
| 弱搭配 | 强搭配 |
|---|---|
| big problem | major / pressing / serious problem |
| big difference | substantial / striking / marked difference |
| good evidence | compelling / convincing / hard evidence |
| big change | profound / sweeping / drastic change |
| good reason | compelling / sound / valid reason |
| bad effect | adverse / detrimental / harmful effect |
| big role | pivotal / crucial / instrumental role |
| good opportunity | golden / ample / unique opportunity |
3.3 学 collocation 的 3 个工具
学 collocation 比学单词难 —— 字典只给单词,不给搭配。下面 3 个工具是必备:
| 工具 | 用法 |
|---|---|
| Oxford Collocations Dictionary | 查每个词的标准搭配 |
| ozdic.com | 免费在线版本,移动端友好 |
| COCA(Corpus of Contemporary American English) | 看真实使用频率 |
每天读 IELTS passage 时,重点记 5-10 个新 collocation——比记 5-10 个新单词更有效。
4. Nominalization(名词化)
Nominalization 是把动词转成名词——是学术写作的核心技巧。学术语篇 70% 由名词化句驱动,而口语 70% 是动词驱动。
4.1 5 种常见 nominalization
下面 5 个动词在学术写作里几乎都以名词形式出现——掌握这 5 个就覆盖 60% 名词化场景。
| 动词 | 名词形式 | 例句 |
|---|---|---|
| decide | decision | "After much deliberation, the decision was reached." |
| react | reaction | "The reaction to the policy was mixed." |
| assume | assumption | "Underlying this approach is the assumption that..." |
| interpret | interpretation | "Different interpretations of the data lead to..." |
| recommend | recommendation | "The recommendation rests on three pillars..." |
4.2 Nominalization 的写作功效
对比同一意思的两种写法:
口语化(动词主导): "We tested the hypothesis. Then we found that it was wrong. So we changed our approach."
学术化(名词化主导): "Following testing of the hypothesis and the discovery of its inadequacy, a revision of the approach was undertaken."
学术化版本更紧凑、更客观、更适合学术语境。但也要警惕过度使用——nominalization 过密会让句子僵硬难读。每段 1-2 处 nominalization是健康分布。
5. 学术 vs 口语词汇对照
学术写作最大的扣分点是用了 informal 词汇。下面 25+ 对照覆盖最常见的"换词需求"。
| 口语 | 学术 |
|---|---|
| a lot of | a great deal of / a substantial amount of |
| kids | children / young people |
| stuff / things | items / aspects / matters |
| get | obtain / acquire / receive |
| big | substantial / considerable / significant |
| good | beneficial / advantageous / favourable |
| bad | detrimental / adverse / unfavourable |
| many | numerous / a wide range of / a multitude of |
| show | demonstrate / illustrate / reveal |
| find out | discover / ascertain / establish |
| think | argue / contend / posit / hypothesise |
| make sure | ensure / guarantee |
| find | identify / discern |
| start | commence / initiate |
| end | conclude / terminate / cease |
| use | utilise / employ / deploy |
| need | require / necessitate |
| also | furthermore / moreover / in addition |
| but | however / nevertheless / yet |
| so | therefore / consequently / hence |
| and so on | and the like / among others |
| a bit | somewhat / slightly / marginally |
| for example | for instance / as a case in point |
| in fact | indeed / arguably |
| really | particularly / notably / strikingly |
5.1 学术写作绝对禁忌
下面这些词学术写作绝对不要出现——一旦出现立刻被扣 0.5-1 分:
| 禁忌词 | 替代 |
|---|---|
| gonna / wanna | going to / want to |
| gotta | have to / must |
| 'cause | because |
| sort of / kind of | somewhat / rather |
| like(填充词) | (删除) |
| you know | (删除) |
| stuff | items / aspects |
| awesome / cool | impressive / remarkable |
6. 词族学习法
AWL 是 570 个词族 (word families)——不是 570 个单词。一个词族 = 主词 + 派生词(noun / verb / adj / adv 4 种)。学一个词族 = 学 4 种形态,效率比单词高 4 倍。
6.1 词族的 4 种形态
以 "analyse" 为例:
| 形态 | 词 | 例句 |
|---|---|---|
| Verb | analyse | "The committee analysed the data." |
| Noun | analysis | "A thorough analysis revealed..." |
| Adjective | analytical | "An analytical approach is needed." |
| Adverb | analytically | "Approached analytically, the problem..." |
6.2 高频词族举例
下面 7 个高频词族都4 种形态俱全——是练习"词族学习法"的标准入门集合。
| 词族 | Verb | Noun | Adjective | Adverb |
|---|---|---|---|---|
| assess | assess | assessment | assessable | -- |
| establish | establish | establishment | established | -- |
| identify | identify | identification | identifiable | -- |
| imply | imply | implication | implicit | implicitly |
| distinguish | distinguish | distinction | distinct | distinctly |
| constitute | constitute | constitution | constituent | -- |
| derive | derive | derivation | derivative | derivatively |
6.3 学习时填表
每学一个 AWL 词族,强制填这 4 种形态的表。没有派生词的就标 "--"(部分词族确实只有 1-2 种形态)。这条习惯让你记忆更系统。
7. 5 个词汇学习反模式
词汇学习失败集中在 5 个反模式——这 5 个都让"背了一堆词但用不上"成为常态。识别并戒除是词汇分提升的关键。
| 反模式 | 表现 | 修法 |
|---|---|---|
| 只背 L1-L2 | 知道单词但不会用 | 每词必学 collocation + register |
| 抄同义词列表 | 记 10 个同义词但不知差别 | 每个同义词学 1 个具体语境 |
| 用 AWL 但搭配错 | "do research" / "make a decision" | 用 collocations 字典 |
| 学术语境用 informal 词 | "a lot of kids" / "stuff" | 写作前过 informal 词清单 |
| 追求生僻词 | 用 "ascertain" 代替 "find out"(过度) | 关键 8-12 处用精准词,其余用普通词 |
7.1 追求生僻词为什么是反模式
很多考生炫技用罕见词 —— 但 9 分卷不是"全篇用大词"。用错位的大词比用普通词扣更多分。例:"investigate" 比"look at"学术,但用"interrogate"(审问)显得过度且有暴力含义。精准 > 高级。
7.2 抄同义词列表的隐蔽危险
字典给"investigate / examine / explore / probe / scrutinise"5 个近义词,中国考生全抄下来背——但5 个词的语境差别:
- investigate —— 调查(警察 / 学术)
- examine —— 检查(医生 / 学术)
- explore —— 探索(地理 / 学术)
- probe —— 深入挖掘(质询)
- scrutinise —— 仔细审视(批判性)
记 5 个词不知差别 ≈ 不会用任何一个。修法: 每个词学 1 个具体例句 + register,遇到陌生 register 直接放弃(用安全词)。
