**今天学什么**

今天把昨天拆下来的零件装成一个能带进考场的库：六类功能，每类四句，共 24 句，再逐句改写成你自己的话题。难点不在凑数，而在"改写后功能不变"——很多人一换话题，让步就变成了反对，举例就变成了断言，句子看着漂亮，逻辑已经换了一个人。今天的训练目标是把功能和内容分开：内容可以换，槽位不能少。学完你会有 24 句骨架、24 句改写和一篇 300 词的六功能短文，明天起限时写作时，你调用的就是这套东西。

## 一、今日任务

| 环节 | 时长 | 具体动作 | 产出 |
| --- | --- | --- | --- |
| 1. 筛选旧句 | 8 min | 从 Day 1 的 20 句里每类留 2 句，共 12 句；删掉过长、不顺手、带明显范文痕迹的 | 12 句底稿 |
| 2. 补齐到 24 句 | 22 min | 每类再写 2 句，补足 4 句；每句标出槽位（[X] 对象、[Y] 标准、[Z] 条件）与力度 | 24 句 + 槽位标注 |
| 3. 逐句改写 | 20 min | 每句换成自己的话题（教育／科技／城市／环境各 6 句），只换内容，不换功能与槽位数 | 24 句改写 |
| 4. 功能盲测 | 15 min | 遮住标签，随机抽 8 句改写句判断功能；错 1 句就把该句打回重写 | 盲测记录 |
| 5. 串句成文 | 15 min | 用 8—10 句库里的句子串成 300 词短文，六类各至少出现一次 | 300 词短文 |

第 2 步有一个硬要求：每句必须能填进三个空槽。填不进去的句子，说明它只是好句子，不是功能句——好句子只能背，功能句才能调用。第 3 步改写时先把原句的槽位数字写下来（例如"让步一槽、转折一槽、结论一槽"），改完再数一遍，数字不对就是功能漂移。

## 二、核心词汇与搭配

| 词/短语 | 音标 | 词性 | 释义 | 高频搭配 | 例句（含译） | 语域 |
| --- | --- | --- | --- | --- | --- | --- |
| concede | /kənˈsiːd/（≈克恩西德） | v. | 承认（对方某点成立） | concede that; concede a point | The report concedes that uptake has been slower than planned. 报告承认采用速度低于计划。 | 学术 |
| warrant | /ˈwɒrənt/（≈沃若恩特） | v. | 使……有正当理由 | warrant attention; warrant a conclusion | A single pilot does not warrant a national rollout. 一次试点不足以支持全国推广。 | 学术 |
| hinge on | /hɪndʒ ɒn/ | phr. v. | 取决于 | hinge on whether; the argument hinges on | The verdict hinges on whether the sample was random. 结论取决于样本是否随机抽取。 | 学术 |
| insofar as | /ˌɪnsəˈfɑːr əz/ | conj. | 就……而言，在……范围内 | insofar as it affects; valid insofar as | The claim holds insofar as it is limited to households with a car. 该主张只在有车家庭的范围内成立。 | 学术 |
| conversely | /ˈkɒnvɜːsli/（≈科恩韦斯利） | adv. | 相反地 | conversely, …; and conversely | Cities that priced entry saw speeds rise; conversely, those that widened roads saw gains disappear within three years. 收费的城市车速上升；相反，拓宽道路的城市三年内收益消失。 | 学术 |
| arguably | /ˈɑːɡjuəbli/ | adv. | 可以说，按理说 | arguably the strongest; arguably, … | Arguably the strongest objection is not cost but fairness. 可以说最强的反对意见不是成本，而是公平。 | 学术/媒体 |
| thereby | /ˌðeəˈbaɪ/（≈兹艾拜） | adv. | 从而，借此 | thereby reducing; thereby making | The levy raises the cost of a short trip, thereby reducing the number taken. 收费提高了短途出行的成本，从而减少了出行次数。 | 学术 |
| albeit | /ɔːlˈbiːɪt/（≈奥尔比伊特） | conj. | 尽管，虽然（后接短语） | albeit slowly; albeit with caveats | The scheme worked, albeit at a political cost few had forecast. 该方案奏效了，尽管付出了少有人预见的政治代价。 | 学术 |
| prevailing | /prɪˈveɪlɪŋ/（≈普里韦利英） | adj. | 占主导的，普遍的 | the prevailing view; prevailing conditions | The prevailing view is that congestion is a capacity problem; the evidence points to a pricing problem. 主流观点认为拥堵是容量问题，证据却指向定价问题。 | 学术 |
| counterargument | /ˈkaʊntərɑːɡjumənt/ | n. | 反论，对方的论证 | anticipate a counterargument; meet the counterargument | A counterargument that is never answered reads as an omission, not as balance. 提出却不回应的反论，读起来是遗漏，不是平衡。 | 学术 |

这一组词服务于"把逻辑说出口"，不是用来堆难度。concede 与 admit 的差别在语域与分量：concede 是论辩中的战术承认，admit 更接近认错，考试作文里几乎总用 concede。warrant 与 justify 都表示"使正当"，但 warrant 的主语通常是证据或行为，justify 的主语可以是人：The evidence warrants a review，不说 The evidence justifies me to review。

insofar as 是最容易被滥用的一个。它表示"在某个范围内成立"，不是"因为"，也不是"只要"。写成 The policy works insofar as it is funded 是准确的；写成 Insofar as the policy works, we should expand it 就把限定偷换成了因果，读者会觉得你在含糊其辞。arguably 的位置也值钱：句首 arguably 修饰整句，句中 arguably 只修饰紧邻的那个词，力度不同。

## 三、语言点：功能标记要外露，但不能喧宾夺主

**规则**

1. **一句一个显性标记。** Although the scheme is costly, however it works. 在书面语里是错误，不是强调。两个标记叠加，读者要花时间判断哪个管哪个，这在 40 分钟的文章里是纯损失。
2. **标记的位置决定辖域。** 句首标记管整句（Admittedly, the cost is high.）；句中标记只软化它依附的那个断言（The cost is, arguably, the lesser problem.）。想弱化判断就把标记往里挪，想明确立场就放到句首。
3. **同一个标记全篇不超过两次。** 第三次出现时，读者开始看标记而不是看内容，文章的"论证感"会掉成"连接词练习"。
4. **标记之后必须真的执行该功能。** 写了 Admittedly 却继续攻击对方，是功能漂移；写了 The clearest case is 却只给一个泛泛的例子，是承诺落空。
5. **改写时保留槽位数量。** 原句若含"让步＋转折＋结论"三槽，改写后仍是三槽，只换内容。减槽等于换了逻辑，加槽则会让句子超过 30 词。

| 功能 | 默认标记 | 力度 | 常见风险 |
| --- | --- | --- | --- |
| 引入 | The argument that… / It is often assumed that… | 中性 | 变成复述题目 |
| 让步 | Admittedly, … / It is true that… / For all its… | 中 | 让得太多，立场模糊 |
| 举例 | The clearest case is… / This is visible in… | 中 | 例子不可核查 |
| 因果 | This is not because… but because… / …, thereby… | 强 | 把相关当因果 |
| 反驳 | Yet even here… / That would hold if… | 强 | 打成稻草人 |
| 结论 | The question is therefore… / On balance… | 中强 | 重复开头 |

**强弱对比**

| 弱 | 强 | 差别 |
| --- | --- | --- |
| Also, the scheme is expensive. | The scheme is expensive, and the cost falls on the drivers least able to pay. | 前者只是追加信息，后者把成本落到具体的人身上，能接反驳 |
| But some people disagree. | The objection is not that charging works, but that it works regressively. | 前者没有内容，后者替对方把话说完，反驳才有对象 |
| So we should do it. | If the objection is about fairness rather than efficacy, the remedy is an exemption, not abandonment. | 前者是口号，后者用条件句把结论收窄成可执行的方案 |

**常见误用**

1. **装饰性序号。** Firstly、Secondly、Last but not least 只标顺序，不标关系。如果两段之间是转折，写 Secondly 会让读者误以为你在并列，读到第三段才发现方向变了。
2. **中文式双连。** Although…, but… 是直译习惯。英语里让步从句已经承担了转折，主句不再加 but；要强调就在主句用 still 或 nevertheless，且只用一个。
3. **伪反驳。** However, I still believe… 后面接的还是原立场，没有换维度、没有新证据。这不是反驳，是重申，读者会认为你没读懂对方。

**什么时候用、什么时候不用。** 考试作文里逻辑外露是优点：阅卷人平均只花几分钟，标记能替他省力。专栏与散文里则相反，标记太多会显得说教，成熟的写法是让段落自己转弯。学术写作居间：标记少而准，一个 Admittedly 胜过三个 However。今天建库时全部用显性标记，是为了让你在压力下有东西可抓；等你写顺了，再逐步删掉一半。

## 四、句型与范例

| 功能 | 句式骨架 | 中文 |
| --- | --- | --- |
| 引入 | It is often assumed that [X]; the assumption is worth testing against [Y]. | 人们常假设 X；这个假设值得用 Y 来检验。 |
| 引入 | The debate over [X] usually pits [A] against [B], which obscures [C]. | 关于 X 的争论通常把 A 与 B 对立，反而遮住了 C。 |
| 让步 | Admittedly, [对方最强点] — and that is the strongest version of the case. | 诚然，……，而这已是该论点最强的版本。 |
| 让步 | For all its [优点], the argument never asks [关键问题]. | 尽管有……的优点，该论证从未追问…… |
| 举例 | The clearest case is [地点/机构], where [数字] changed by [比例] in [时间]. | 最清楚的例子是……，那里……在……内变化了…… |
| 举例 | This is not a hypothetical: [案例] has run the experiment for [时长]. | 这不是假设：……已经做了……年的实验。 |
| 因果 | This is not because [X] causes [Y], but because [X] changes the [成本/激励/信息] behind [Y]. | 这不是因为 X 直接导致 Y，而是因为 X 改变了 Y 背后的…… |
| 因果 | [政策] raises the cost of [行为], thereby reducing [结果]. | ……提高了……的成本，从而减少了…… |
| 反驳 | That objection would hold if [条件]; in practice, [事实]. | 如果……，该反对才成立；现实中…… |
| 反驳 | Yet even here, the objection argues for [修正], not for [放弃]. | 即便在此，该反对也只支持……，不支持放弃。 |
| 结论 | The question is therefore not whether [X], but [条件]. | 因此问题不是是否 X，而是…… |
| 结论 | On balance, [立场] is defensible on [标准], and vulnerable only on [限制]. | 总体而言，……在……标准上站得住，只在……上可被质疑。 |

**改写演示：功能不变，内容全换**

| 原句（教育） | 改写（城市） | 功能核对 |
| --- | --- | --- |
| Admittedly, smaller classes are expensive, and that is the strongest version of the case against them. | Admittedly, congestion charges hit low-income drivers hardest, and that is the strongest version of the case against them. | 让步一槽，保留；"最强版本"未动 |
| The clearest case is Finland, where class size fell by a fifth in a decade. | The clearest case is Stockholm, where traffic fell by a fifth in a decade. | 举例一槽，地点与指标替换 |
| This is not because smaller classes raise scores directly, but because they change how much attention each pupil gets. | This is not because charges cut traffic directly, but because they change the cost of each trip. | 因果两槽（否定错误原因＋真实机制），保留 |
| The question is therefore not whether class size matters, but which pupils gain most. | The question is therefore not whether charging works, but who should be exempt. | 结论重构，保留 |

**范文：147 词（六类功能齐备）**

> The case for charging drivers to enter city centres is usually framed as a tax on motorists. That framing is convenient, and it is wrong: a charge prices a scarce resource that is currently free at the point of use.
>
> Admittedly, the burden falls hardest on those who can least avoid it. A delivery driver, unlike a commuter, cannot choose to travel at six in the morning. Yet even here the objection argues for exemptions, not for abandoning the charge.
>
> Singapore has run such a scheme since 1975, and average speeds inside the zone have stayed above 20 km/h for most of that period. The mechanism is not mysterious: when a trip carries a price, some trips disappear, and the road that remains is worth more per minute.
>
> The question is therefore not whether to price access, but who should be exempt, and on what evidence.

批注：第一段完成"引入＋纠正框架"（六类里的引入）；第二段 Admittedly 让步、Yet even here 反驳，两槽相接；第三段举例（新加坡）与因果（机制）各一句，举例给事实，因果给解释；末段用 The question is therefore not whether… but… 收束，既回应题目又抬高一档。全文 147 词，没有 firstly、moreover，六类功能仍然齐全，这就是"结构靠句子，不靠连接词"。

## 五、练习

**A 词汇与搭配（8 题）**

1. 标功能：Admittedly, the data are incomplete.／The clearest case is Bogotá.／That would hold if fares were the only cost.
2. 搭配填空：concede a ______；warrant a ______；hinge on ______。
3. 选词（arguably / thereby）：The reform is ______ the most consequential since 2010.／It cuts the fee for small firms, ______ lowering the barrier to entry.
4. 语域改写：把 "A lot of people reckon the plan won't work." 改成学术书面语。
5. 词形：prevailing → 动词；arguably → 形容词；counterargument → 动词短语（两个词）。
6. 改错：Although the scheme is costly, but it works.
7. 辨义：用一句话说明 concede 与 admit 的差别，并各造一句。
8. 填空（insofar as / albeit）：The finding is useful ______ it applies to cities with rail.／The reform passed, ______ by a narrow margin.

**B 句法（6 题）**

1. 改写保功能：把 "Some say it is too expensive." 写成一组"让步＋反驳"，功能槽位不得减少。
2. 去双标记：Although the data are limited, however they are consistent.
3. 移动标记并说明力度变化：The plan will, arguably, cut emissions. → 句首版。
4. 拆句保槽：Although the scheme is expensive and although uptake has been slow, it has cut congestion, which suggests it should be extended. 拆成 2—3 句，保留让步、转折、结论三槽。
5. 显性化因果：The policy failed. It was too complex. 用因果标记合并成一句。
6. 识别伪反驳：指出下面哪一句没有换维度。"Charging is regressive. However, I still think charging is wrong. Furthermore, it is unpopular."

**C 输出（2 题）**

1. 24 句库：六类各 4 句，每句带槽位标注与力度标记。
2. 300 词短文：用库中 8—10 句串成一篇，六类各至少一次，话题自选，不得出现 firstly／moreover／in conclusion。

## 六、参考答案

**A**

1. 让步；举例；反驳（条件式反驳）。
2. concede a point；warrant a conclusion；hinge on whether（或 hinge on the assumption）。
3. arguably；thereby。
4. It is widely assumed that the plan will fail.（把口语主语换成无人称被动，语气更稳。）
5. prevail；arguable；argue against（或 counter）。
6. Although the scheme is costly, it works. 或 The scheme is costly, but it works.（二选一，不能并用。）
7. concede 是论辩中承认对方某点成立，admit 更接近认错且语域更口语。例：The minister conceded that the deadline had slipped.／He admitted that he had lost the file.
8. insofar as；albeit。

**B**

1. Admittedly, the scheme is expensive; that, however, is an argument for phasing it in, not for dropping it.（让步一槽、转折一槽、结论一槽，与原文等量。）
2. Although the data are limited, they are consistent.（删 however；从句已承担转折。）
3. Arguably, the plan will cut emissions.（句首版修饰整句，等于对"会减排"这个命题整体加限定；句中版只弱化 cut emissions 这个短语，语气更轻。）
4. The scheme is expensive and uptake has been slow. Even so, it has cut congestion. That record suggests it should be extended.（三句，三槽齐全，每句都在 30 词以内。）
5. The policy failed not because its aims were wrong but because its design was too complex.（否定错误原因＋给出真实原因，一槽未少。）
6. 第二句 However, I still think charging is wrong. 只是重申立场，没有新维度；第一句提出了"累退"这一具体问题，第三句提出了"不受欢迎"这一政治成本，二者都算换维度。

**C 评分维度**

| 项目 | 合格线 |
| --- | --- |
| 24 句 | 六类各 4 句，每句标明槽位与力度 |
| 24 改写 | 功能不变，槽位数不变，话题不重复超过 6 次 |

## 七、今日输出与自查

| 检查项 | 合格线 | 我的记录 |
| --- | --- | --- |
| 句库规模 | 24 句，六类均衡 |  |
| 槽位 | 每句可填 2—3 个空，且改写后数量不变 |  |

产出文件名：功能句库_Day02.md、功能句改写_Day02.md、六功能短文_Day02.md（300 词）；全程 80 分钟。建库时按功能分组，不要按话题分组；按话题分组，考场上想不起该用哪一类，库就废了。

## 八、明日预告

Day 3 给句子减负：只练关系从句、分词短语、让步句三种，各写 5 句，每句不超过 30 词，且不能有悬垂修饰。今天库里有些句子已经接近 30 词上限，明天要把它们拆开再装回去——减负不是写短，是在同样信息量下少用一个从句。
