How to Learn Advanced English Vocabulary (Chinese Edition) | Lesson No.017 | Master Paraphrase, Reformulation and Meaning-Preserving Vocabulary Choices | 第017课：掌握改述、重述与不失真换词

Series ID: EDKS-ADV-VOC-ZH-0017 · Advanced English Vocabulary (Chinese Edition) · Lesson No.017 · Batch 05 · C1 → C2 · 简体中文辅助

A good paraphrase changes the language without silently changing the claim.
好的改述，会换语言，不会偷偷换结论。

You read: “The evidence suggests that the intervention may improve retention under some conditions.” You rewrite: “The research proves that the intervention improves memory.” The second sentence is shorter, but it is not a paraphrase. It has strengthened the evidence, removed uncertainty, broadened the conditions and changed retention into the wider idea of memory.

这就是高级词汇改述最危险的地方：表面意思“差不多”，事实边界却已经移动。学习者为了避免重复、追求正式、使用高级词，常常在不知不觉中把 may 改成 will，把 suggest 改成 prove，把 some 改成 all，把 contribute to 改成 cause。

Advanced paraphrasing is therefore not a synonym game. It is controlled semantic transformation. You may change vocabulary, word class, clause structure, information density or register, but you must know which parts of the proposition are allowed to move and which must remain stable.

Different words are not enough. The same proposition must survive.

“换了词”还不够。真正的要求是：原来的命题必须活下来。

This lesson owns the Mandarin-supported C1–C2 lexical route for meaning-preserving paraphrase and reformulation. It does not replace Lesson No.003 on one-to-one translation, Lesson No.006 on near-synonym precision, Lesson No.007 on academic vocabulary functions, Lesson No.016 on word-class shifts, or broader writing/discussion owners. Here the specific learner problem is: how to change the expression while keeping the intended meaning calibrated.

---

1. Paraphrase is not synonym replacement | 改述不是“把每个词换成同义词”

Weak paraphrase strategy:

1. underline content words;
2. open thesaurus;
3. replace each word with a “more advanced” synonym;
4. keep the sentence shape unchanged.

This often creates unnatural collocations and semantic drift.

Stronger strategy:

1. state the meaning in simple English;
2. identify what must not change;
3. choose a different expression route;
4. compare the new claim with the old claim;
5. check collocation/register.

改述先做“意义建模”，再做“语言改造”。

2. Build the invariants first | 先找“不能变的东西”

Before paraphrasing, mark the semantic invariants:

• Core proposition: what happened / what is being claimed?
• Certainty: possible, likely, definite?
• Scope: some, many, most, all?
• Cause: cause, contribute, correlate, precede?
• Time: past, present, ongoing, future?
• Agent: who acts or holds responsibility?
• Evaluation: positive, negative, neutral?
• Register: conversational, neutral, academic, professional?

If one of these changes accidentally, you have probably written a new claim rather than a paraphrase.

3. Certainty is one of the easiest things to distort | 最容易改坏的是“确定程度”

Original	Unsafe change	Safer paraphrase
The evidence may indicate…	The evidence proves…	The evidence may suggest…
X is likely to increase…	X will increase…	X will probably increase… / X is expected to increase… where justified
One possible explanation is…	The explanation is…	A plausible explanation is…

Never “improve” the vocabulary by increasing certainty.

4. Scope must survive | 范围必须守住

• some learners ≠ learners;
• many cases ≠ all cases;
• under certain conditions ≠ generally;
• in this sample ≠ in the population;
• for this task ≠ for English learning as a whole.

Example:

Original: “In this sample, some learners improved after repeated retrieval.”
Unsafe: “Retrieval improves learners.”
Safer: “Some participants in the sample improved following repeated retrieval.”

改述不能把限定条件删掉。

5. Causality must survive | 因果强度必须守住

Relation	Examples
cause	cause, lead to, result in
partial contribution	contribute to, play a role in
association	be associated with, correlate with
sequence	precede, follow

Changing is associated with to causes is not paraphrase. It changes the relationship.

6. Agency must survive when responsibility matters | 责任主体不能在改述中消失

Original:

The review team entered the incorrect value.

Changed version:

An incorrect value was entered.

The event remains, but responsibility becomes hidden. That may be acceptable if agency is irrelevant; it is not meaning-neutral when accountability matters.

7. Time and completion status must survive | “计划、正在、已经”不能互换

• plans to implement ≠ implemented;
• is implementing ≠ has implemented;
• began to improve ≠ improved;
• may become available ≠ is available.

Advanced paraphrase protects event stage.

8. Evaluation and stance must survive | 原文的态度也不能被“美化”

Original: “The proposal is ambitious but difficult to implement.”

Unsafe paraphrase: “The proposal is innovative and promising.”

The evaluative stance changed from mixed/cautious to positive.

Safer: “The proposal sets an ambitious goal, although implementation may be difficult.”

9. Paraphrase level 1 — lexical substitution | 第一层：词汇替换

This is the smallest transformation.

• approximately → roughly/about depending on register;
• demonstrate → show, if claim strength remains appropriate;
• substantial → considerable/large, depending on noun and meaning;
• retain → keep, depending on register.

Lexical substitution is safe only when meaning, collocation and register remain compatible.

10. Paraphrase level 2 — word-class shift | 第二层：词性转换

• The team analysed the data. → The analysis of the data…
• The measure is reliable. → The reliability of the measure…
• The result was significant. → The significance of the result…

Lesson No.016 supplies the deeper word-class machinery. In paraphrase, ask whether the shift changes agency, density or topic structure.

11. Paraphrase level 3 — clause restructuring | 第三层：句法重组

Original:

Because the sample was small, the authors interpreted the result cautiously.

Paraphrase:

The authors interpreted the result cautiously because of the small sample.

Another:

The small sample led the authors to interpret the result cautiously.

The third version slightly foregrounds causal influence; check whether that is appropriate.

12. Paraphrase level 4 — information reordering | 第四层：改变信息顺序

Original:

Three limitations should be considered before the result is generalised.

Paraphrase:

Before generalising the result, we should consider three limitations.

Meaning is close, but the second version introduces we, making agency explicit. That may improve or change the tone.

13. Paraphrase level 5 — compression | 第五层：压缩

Expanded:

The evidence does not allow us to determine with confidence whether the change caused the improvement.

Compressed:

The evidence is insufficient to establish causation.

This is a strong paraphrase if causation accurately captures the original relation.

14. Paraphrase level 6 — expansion | 第六层：展开

Compressed:

The finding has limited external validity.

Expanded:

The finding may not apply reliably to people, settings or conditions beyond those included in the study.

Expansion is useful when a technical phrase needs to be explained to a wider audience.

15. Paraphrase level 7 — register shift | 第七层：换语域

Meaning: evidence is weak.

• Conversation: “There isn’t much evidence for that.”
• Neutral: “The claim is weakly supported.”
• Academic: “The available evidence provides limited support for the claim.”

The proposition remains similar while lexical density and interpersonal stance change.

16. Paraphrase level 8 — audience shift | 第八层：换读者

Technical:

The intervention produced a transient improvement in retrieval accuracy.

General reader:

The intervention improved retrieval accuracy, but the benefit did not last.

Audience adaptation can preserve meaning while replacing specialist vocabulary.

17. Simplification is a form of advanced control | 能把复杂话说简单，也是高级能力

Advanced learners sometimes fear that simpler wording sounds less intelligent. That belief produces inflated language.

Compare:

Inflated: “The utilisation of the framework facilitated the identification of discrepancies.”
Clear: “Using the framework helped identify discrepancies.”

The second version preserves the mechanism and reduces processing cost.

18. Formalisation is not just replacing simple words with long words | 正式化也不是“全部换成长词”

Conversation:

We looked at what went wrong and found two main problems.

Professional:

We reviewed the failure and identified two primary issues.

The improvement comes from genre-appropriate vocabulary and structure, not maximum syllable count.

19. “Show” and “demonstrate” are not always interchangeable | show 与 demonstrate 也有强度差

In evidence-sensitive writing, demonstrate can sound stronger or more formal than show, depending on context. Do not replace suggest with demonstrate simply to avoid repetition.

Paraphrase must preserve evidential force.

20. “Possible”, “plausible” and “probable” are not paraphrase equivalents | possible / plausible / probable 不能轮流换

• possible — can happen/be true;
• plausible — reasonably believable;
• probable — more likely than not / likely, depending on context.

Replacing one with another changes the probability/evaluation model.

21. “Cause” and “contribute to” are not stylistic variants | cause 与 contribute to 不是为了避免重复而互换

Original:

Prior knowledge contributed to better comprehension.

Unsafe:

Prior knowledge caused better comprehension.

The first permits multiple causes. The second assigns direct causality.

22. “Address” and “solve” are not paraphrase equivalents | address 与 solve 也不能随意换

“The policy addresses the problem” means it deals with/takes action on the problem. “The policy solves the problem” claims successful resolution.

Lesson No.013 already trained this familiar-word sense distinction; paraphrase makes the factual consequence explicit.

23. “Large”, “substantial” and “significant” do different work | 大、实质、显著也不是一个维度

• large increase — magnitude;
• substantial increase — considerable magnitude/importance;
• significant increase — important/notable, or technical statistical meaning in some contexts.

Paraphrase by function, not by thesaurus proximity.

24. “Weak evidence” can be paraphrased several ways—but not identically | weak evidence 可以换路线，但要看具体弱在哪里

• limited evidence;
• insufficient evidence;
• inconclusive evidence;
• weakly supported claim;
• evidence that does not establish X.

Each version classifies the weakness differently. Choose based on the actual problem.

25. Use definition paraphrase | 用“定义型改述”代替机械同义词

Target: volatile.

• volatile market;
• market that changes sharply and unpredictably;
• market with unstable price movements.

Definition paraphrase is especially useful when the audience may not know the technical term.

26. Use example paraphrase | 用例子展开抽象词

Target: constraint.

“The project faces several constraints” → “The project is limited by budget, staff capacity and the deadline.”

The second version expands the category into examples. It is not a perfect paraphrase if the original constraints were different; context matters.

27. Use mechanism paraphrase | 把抽象结果改写成“怎样发生”

Original:

The method improved reliability.

Mechanism expansion:

The method reduced variation between repeated measurements, making the results more reliable.

This adds information. Therefore it is only a valid paraphrase if the mechanism is actually supported.

解释得更详细，不等于可以自由发明机制。

28. Use contrast paraphrase | 用对比说明概念

Target: efficient.

An efficient process achieves the intended result with relatively little waste of time, money or resources.

Contrasting with effective can sharpen the paraphrase: effective = works; efficient = works with limited waste.

29. Use negated paraphrase carefully | 用否定改述时，小心逻辑强度

“Unlikely” is not always exactly equivalent to “not likely”; “not impossible” is very different from “possible” in pragmatic force; “not insignificant” often implies more than simple negation.

Negation changes emphasis and sometimes stance. Do not assume mathematical equivalence creates communicative equivalence.

30. Active/passive reformulation can change focus | 主动被动改写会改变焦点

• The team measured the outcome. → The outcome was measured by the team.
• The team measured the outcome. → The outcome was measured.

The first largely preserves the actor; the second removes it. Paraphrase accuracy depends on whether agency is part of the intended information.

31. Positive/negative reformulation can change tone | 正说反说也会改变语气

• The plan is difficult to implement.
• The plan is not easy to implement.

These are close but not identical in tone. The first directly classifies difficulty; the second frames it relative to ease.

Meaning preservation includes pragmatic tone, not only dictionary denotation.

32. Paraphrasing from Chinese should pass through meaning, not word substitution | 中文→英文改述也要先过“意义层”

Chinese idea: “这个方法在一定程度上提高了效率，但效果不稳定。”

Possible English:

The method improved efficiency to some extent, but the benefit was inconsistent.

Alternative:

The method produced a modest improvement in efficiency, although the effect was not consistent.

Before deciding these are equivalent, check whether to some extent really means modest in the original context. It may not.

33. Paraphrase can reveal hidden ambiguity | 改述有时会暴露原句本身就不清楚

Original:

The results were significant.

What does this mean?

• statistically significant?
• important?
• large?
• meaningful in practice?

If you cannot paraphrase the sentence precisely, the original may need clarification before rewriting.

34. Use “paraphrase triangles” | 做三角改述：原句—简单英语—目标版本

Step 1: original.

The evidence is insufficient to establish a causal relationship.

Step 2: simple English.

We do not have enough evidence to say that one thing caused the other.

Step 3: new formal version.

The available evidence does not support a firm causal conclusion.

The simple middle version acts as a semantic checkpoint.

35. Use “back-translation” as a diagnostic, not as proof | 反向翻译可以检查，但不能证明完全等义

After paraphrasing, explain both versions in simple Chinese or simple English. If they require noticeably different explanations, investigate the drift.

Back-translation is a useful alarm, not a perfect equivalence test.

36. Use one idea across three vocabulary densities | 同一个意思，练三种词汇密度

Idea: results vary because the groups started at different levels.

• Simple: “The results differ partly because the groups started at different levels.”
• Neutral academic: “Differences in baseline level may partly explain the variation in outcomes.”
• Technical: “Baseline differences may account for part of the observed outcome variability.”

Check whether technical compression has introduced any extra assumption.

37. Use one idea across three audiences | 同一个意思，换三种读者

Idea: the result is uncertain because the sample is small.

• Student: “We should be careful because only a small number of people were studied.”
• Professional: “The small sample limits confidence in the result.”
• Academic: “The small sample size constrains the certainty with which the finding can be generalised.”

The invariant is uncertainty caused by sample size.

38. Use one idea across spoken and written English | 同一个意思，口语与写作版本不同

• Spoken: “What I mean is that the result depends a lot on context.”
• Written: “The result is highly context-dependent.”

The written form compresses what speech often unpacks explicitly.

39. Use paraphrase to test understanding | 会不会改述，本身就是理解测试

If a learner can only repeat a sentence but cannot restate it simply, lexical understanding may be shallow.

Ask for:

• simple-English restatement;
• formal restatement;
• one example;
• one contrast;
• one shorter version.

Each transformation exposes a different aspect of lexical depth.

40. Use paraphrase to test near-synonym boundaries | 改述也能测试近义词是否真的理解

Original: “The explanation is plausible.”

Ask the learner to paraphrase without plausible. If they write “The explanation is possible,” some nuance may be lost. A better expansion: “The explanation is reasonably believable, although it is not yet proven.”

Paraphrase exposes the semantic centre.

41. Use paraphrase to test polysemy | 多义词也能通过改述检查当前词义

Sentence: “The report addresses three limitations.”

Paraphrase: “The report deals with three limitations.”

If the learner writes “The report gives three addresses,” Lesson No.013’s familiar-word alarm has failed.

42. Use paraphrase to test idioms | 习语真正理解以后，必须能还原成普通英语

• gain traction → begin receiving support/progress;
• on shaky ground → weakly supported;
• cast doubt on → reduce confidence in;
• strike a balance → find a workable compromise.

Lesson No.012’s plain-English fallback is a paraphrase skill.

43. Use paraphrase to test academic vocabulary | 学术词真正掌握，要能展开解释

• external validity → whether findings apply beyond the studied sample/setting;
• constraint → factor that limits options;
• feasibility → whether something can realistically be done;
• robust method → method that remains reliable under variation/challenge.

If the learner can only provide another abstract noun, understanding may still be circular.

44. Do not paraphrase technical terms when the term itself matters | 技术术语不能为了“避免重复”乱换

In specialist writing, repeated technical terminology may be desirable because consistency matters more than lexical variety.

If the paper defines working memory, do not rotate through short-term mental storage, temporary cognition space, immediate memory system merely to avoid repetition. You may accidentally introduce different concepts.

专业术语重复，有时比“漂亮换词”更准确。

45. Lexical variety is not a goal by itself | 词汇多样性不是独立目标

Repeated use of evidence may be clearer than alternating evidence, proof, support, indication, demonstration when those words do not mean the same thing.

Use variation when the relation changes or when a genuine equivalent fits. Do not vary for decoration.

46. The FENCE paraphrase system | FENCE 改述控制系统

Fence	Question	Action
F0 Proposition	What exactly is being claimed?	simple-English restatement
F1 Certainty	How strong is the claim?	preserve modal/evidence force
F2 Scope	Who/what/how much?	keep quantifiers/conditions
F3 Relation	Cause, association, sequence?	preserve logical relation
F4 Agency/time	Who acted, and when?	protect event structure
F5 Route	Lexical, structural, compression, expansion?	choose transformation
F6 Register	Who is the reader/listener?	adjust density/tone
F7 Verification	Did meaning drift?	compare/back-paraphrase
F8 Transfer	Can I paraphrase in another context?	new-topic practice

47. Build a paraphrase audit table | 建立“改述审计表”

Check	Original	New version
certainty	may	may / equivalent?
scope	some learners	some learners?
cause	contribute to	contribute / cause?
time	planned	planned / completed?
agent	review team	still visible?
stance	cautious	still cautious?

This is especially useful for academic summaries and source-based writing.

48. Build “simplify without losing” cards | 做“变简单，但不丢信息”卡

Front:

The evidence is insufficient to establish a causal relationship.

Back:

We do not have enough evidence to say that one thing caused the other.

Then ask what information was preserved: insufficient evidence + causality not established.

49. Build “formalise without inflating” cards | 做“更正式，但不夸张”卡

Simple:

We don’t know enough yet.

Professional:

The available information is not yet sufficient to support a firm conclusion.

Do not convert it into “There is no evidence,” which would be stronger.

50. Build “compress without hiding” cards | 做“压缩，但不把关键条件压没”卡

Long:

The result may not apply to other settings because the study included only one type of school.

Compressed:

The single-school sample limits generalisability.

Useful compression depends on the reader understanding generalisability.

51. Build “expand the technical term” cards | 技术词要能展开成人话

• feasibility → whether the plan can realistically be carried out;
• reliability → whether a measure produces stable/consistent results;
• constraint → something that limits available options;
• mitigation → action that reduces severity or risk.

This protects both understanding and teaching ability.

52. Worked case: Maren overstrengthens a source | 案例一：Maren 改述时把证据强度写大了

Source-like teaching sentence:

Repeated retrieval may improve later access to the target vocabulary.

Maren writes:

Retrieval practice ensures that learners remember vocabulary.

Her tutor highlights four changes:

• may disappeared;
• improve access became ensures remember;
• target vocabulary became all vocabulary;
• later access became general remembering.

Safer paraphrase:

Practising retrieval may make the target vocabulary easier to recall later.

中文分析：词变简单了，但四个关键条件都守住了。这才是改述。

53. Worked case: Iona simplifies technical vocabulary for a younger reader | 案例二：Iona 给普通读者降密度

Technical sentence:

The intervention improved short-term retrieval but produced limited evidence of durable transfer.

Iona writes:

The activity helped learners recall the words soon afterwards, but there was little evidence that the benefit lasted or carried over to new tasks.

The sentence becomes longer, but meaning becomes more accessible.

中文分析：简化不一定让字数变少。真正目标是让读者更少依赖专业词也能得到同一个信息结构。

54. Worked case: Leonie changes register for a meeting | 案例三：Leonie 把报告语言改成会议语言

Written report:

The implementation remains subject to approval from the review committee.

Meeting version:

We can’t implement it yet because the review committee still needs to approve it.

The event status remains the same: implementation has not begun because approval is pending.

55. Worked case: one paraphrase reveals ambiguity | 案例四：改不出来，因为原句本来就模糊

Original:

The programme produced a significant improvement.

Does significant mean statistically significant, practically important or simply large/notable? Before paraphrasing, the writer must clarify the intended sense.

A paraphrase exercise can therefore diagnose ambiguity in the source sentence.

56. Use source-based paraphrase ethically | 改述不是“换几个词就不用引用”

Paraphrasing someone else’s idea does not make the idea yours. In academic and professional contexts, attribution requirements depend on the task and source conventions. A paraphrase generally changes wording while the underlying idea still belongs to the source.

Do not use synonym replacement to disguise copied structure.

本课训练语言转换，不提供“规避引用”的方法。

57. Read, close, restate, verify | 一个非常实用的改述流程

1. Read the source carefully.
2. Identify the proposition and invariants.
3. Close or look away from the sentence.
4. Restate it in simple English from meaning.
5. Build the target register.
6. Compare with the original.
7. Restore any lost condition or qualifier.

This reduces dependence on surface wording.

58. Use “meaning notes” before paraphrasing | 改述前先写意义笔记

Source:

Under certain conditions, the intervention appears to reduce short-term error rates.

Meaning notes:

• only certain conditions;
• uncertain/appearance, not proof;
• reduces errors;
• short-term only.

Then paraphrase. The notes act as rails.

59. Use one sentence, five paraphrases | 一句话练五条路线

Original:

The small sample limits confidence in the conclusion.

• Simple: “Because only a small number of people were studied, we cannot be very confident in the conclusion.”
• Noun-focused: “The limited sample size reduces confidence in the conclusion.”
• Formal: “The small sample size constrains the certainty of the conclusion.”
• Expanded: “The conclusion should be interpreted cautiously because the study included only a small sample.”
• Spoken: “We need to be careful with that conclusion because the sample was small.”

Then compare exactly what changed.

The target is not more wording variation. The target is more reliable semantic control.

64. A 12-week progression | 12 周改述路线

Weeks	Focus	Evidence of progress
1–2	simple restatement + invariants	less accidental meaning change
3–4	lexical + word-class transformation	more flexible vocabulary use
5–6	certainty/scope/causality	better academic calibration

65. The first weak link diagnostic | 第一个弱点诊断

Symptom	Likely first weak link	Repair
I change words but copy sentence structure.	surface-level paraphrase	close source + restate meaning
I accidentally strengthen claims.	certainty control	mark modal/evidence verbs
I generalise too much.	scope control	preserve quantifiers/conditions
I turn association into causation.	logical relation	relation audit
My formal version sounds inflated.	register misconception	formalise structure, not word length
My simple version loses technical meaning.	expansion skill	definition paraphrase
I cannot explain whether two versions are equivalent.	semantic model	meaning notes + back-paraphrase
I vary technical terms unnecessarily.	lexical-variety misconception	preserve terminological consistency

66. Practice A — detect semantic drift | 练习 A：找出哪里“改失真”了

For each pair, identify what changed.

1. Original: “The evidence may suggest a relationship.” Paraphrase: “The evidence proves a relationship.”
2. Original: “Some learners improved.” Paraphrase: “Learners improved.”
3. Original: “X contributed to the delay.” Paraphrase: “X caused the delay.”
4. Original: “The team plans to revise the process.” Paraphrase: “The team revised the process.”
5. Original: “The policy addresses the problem.” Paraphrase: “The policy solves the problem.”
6. Original: “The result was significant.” Paraphrase: “The result was large.”

67. Practice B — simplify without losing meaning | 练习 B：简化但不丢信息

7. The available evidence is insufficient to establish causation.
8. The intervention produced a transient improvement.
9. The finding has limited external validity.
10. The outcome is contingent on regulatory approval.
11. The two measures demonstrate substantial variability.

68. Practice C — formalise without inflating | 练习 C：正式化但不夸大

12. We don’t know enough yet.
13. The two groups were pretty different at the start.
14. The plan might work, but we haven’t tested it.
15. The new rule made things a bit easier.
16. We need to look at the problem again.

69. Practice D — change word class, preserve the claim | 练习 D：换词性，但守住原意

17. The team analysed the responses. Begin the paraphrase with “The analysis…”
18. The measure is reliable. Begin with “The reliability…”
19. The committee decided to continue. Begin with “The decision…”
20. The system failed during testing. Use “failure” without hiding useful timing.
21. The groups differed substantially. Use “difference” or “variation”.

70. Practice E — audience shift | 练习 E：换读者

Rewrite each for a general reader without losing the technical relationship.

22. The sample lacks sufficient heterogeneity to support broad generalisation.
23. The effect appears transient rather than durable.
24. The measure demonstrates limited reliability under variable conditions.
25. The finding is consistent with, but does not establish, the proposed mechanism.
26. Implementation remains contingent on external approval.

71. Answers A | 练习 A 解析

1. Certainty strengthened: may suggest → proves.
2. Scope broadened: some learners → all/generic learners.
3. Causality strengthened: contribution → direct cause.
4. Event status changed: plan → completed action.
5. Outcome strength changed: addressing → solving.
6. Semantic dimension changed: significant is not automatically large.

72. Answers B — model simplifications | 练习 B 参考

7. We do not have enough evidence to say that one thing caused the other.
8. The intervention helped for a short time, but the improvement did not last.
9. The finding may not apply reliably beyond the people or settings studied.
10. The outcome depends on whether regulators approve it.
11. The two measures vary considerably.

These are model routes, not automatic replacements. Check context-specific meaning.

73. Answers C — model formal versions | 练习 C 参考

12. The available information is not yet sufficient to support a firm conclusion.
13. The two groups differed substantially at baseline.
14. The plan may be feasible, but it has not yet been tested.
15. The new rule produced a modest improvement in usability / made the process somewhat easier, depending on intended meaning.
16. The problem requires further review.

74. Answers D — model word-class shifts | 练习 D 参考

17. The analysis of the responses revealed two patterns.
18. The reliability of the measure remains high under repeated testing.
19. The decision to continue was made after the review.
20. The failure occurred during the second stage of testing.
21. There was substantial variation between the groups.

Each answer adds surrounding information to make the new noun form functional rather than ornamental.

75. Answers E — general-reader versions | 练习 E 参考

22. The sample does not include enough different kinds of participants to justify applying the result broadly.
23. The effect seems temporary rather than lasting.
24. The measure is not consistently reliable when conditions change.
25. The finding fits the proposed explanation, but it does not prove that the explanation is correct.
26. The plan cannot be implemented until an external body approves it.

76. How a strong tutor teaches paraphrase | 高水平导师怎样教改述

A weak lesson asks for “different words”. A strong lesson asks:

• What is the proposition?
• How certain is it?
• What limits the scope?
• What logical relation must survive?
• Who acts?
• What stage has been reached?
• Which transformation are you using?
• Why is the new version equivalent?

The learner must justify equivalence, not merely produce variation.

77. The learner should become their own semantic auditor | 最终，学习者要成为自己的“语义审计员”

After paraphrasing, ask:

• Did I strengthen or weaken certainty?
• Did I widen the group or condition?
• Did I change association into cause?
• Did I hide the actor?
• Did I change planned into completed?
• Did I change positive/negative stance?
• Did I replace a technical term with something broader?
• Did I vary wording merely to avoid repetition?

This audit is the real advanced skill.

78. Canonical ownership and collision boundary | 本课的所有权边界

This lesson owns the Mandarin-supported C1–C2 lexical route for meaning-preserving paraphrase, simplification, formalisation, compression, expansion and register shift. It coordinates but does not replace:

• Lesson No.003 — one-to-one translation.
• Lesson No.006 — near-synonym precision.
• Lesson No.007 — academic/professional vocabulary by function.
• Lesson No.016 — nominalisation and word-class shifts.
• Advanced English Lesson No.008 — reformulation inside complex discussion.

79. Recommended reference floor | 推荐参考资源

• Oxford Advanced Learner’s Dictionary — sense distinctions, collocations, labels and examples for checking paraphrase candidates.
• Cambridge Dictionary — definitions, examples, grammar and pronunciation.
• Cambridge Thesaurus — candidate exploration; candidates still require sense/collocation checking.
• Cambridge English Vocabulary in Use: Advanced — C1–C2 vocabulary in context and easily confused choices.
• University of Manchester Academic Phrasebank — function-based academic phraseology that can support controlled reformulation without replacing thinking.

81. Your assignment | 本课作业

Choose one 300–500 word high-quality English source. Select five claims, not five random sentences.

1. Write each claim in simple English.
2. Mark certainty.
3. Mark scope and conditions.
4. Mark causal/logical relation.
5. Mark time and completion status.
6. Mark the agent where relevant.
7. Close the source.
8. Write a neutral paraphrase.
9. Write a simpler audience version.
10. Write a more formal version.
11. Compare all versions with the original.
12. Circle every place where meaning drifted and repair it.

Then choose one technical term from the source and explain why you kept it unchanged or replaced it.

不要评价“我换了多少词”。评价“原来的意义还剩多少”。

82. The final rule | 最后一条规则

Change the route. Preserve the destination.

路线可以换，目的地不能偷偷变。

You may simplify, formalise, compress, expand, nominalise, verbalise, reorder or change register. But if may becomes will, if some becomes all, if associated with becomes causes, or if a planned action becomes a completed action, you have crossed the semantic boundary.

Advanced paraphrase is therefore not vocabulary decoration. It is controlled movement through language.

真正的高级改述，是你能换一种说法，同时让事实、范围、语气和责任全部安全抵达。
