Series ID: EDKS-ADV-VOC-ZH-0021 · Advanced English Vocabulary (Chinese Edition) · Lesson No.021 · Batch 06 · C1 → C2 · 简体中文辅助

Good writing does not avoid repetition at all costs. Good writing repeats what must stay stable and varies what can safely change.
好写作不是“绝对不重复”。好写作会重复必须稳定的概念，只变化那些可以安全变化的表达。

A learner writes evidence in Sentence 1, then replaces it with proof in Sentence 2, support in Sentence 3 and demonstration in Sentence 4 because a teacher once said “avoid repetition”. The paragraph now looks lexically varied—but the meanings have shifted. Evidence is not automatically proof. Support is not automatically demonstration. The reader has to decide whether the writer is discussing one stable concept or four different ones.

这就是高级写作里一个非常常见的误区：把“词汇多样性”误解成“每次看到重复词就必须换同义词”。结果文章表面上变化很多，真正的概念却变得不稳定。

Research on cohesion gives a more accurate picture. Cambridge materials on cohesion describe lexical cohesion as the recurrence of the same, similar or semantically related words across a text. The Cambridge Handbook of Systemic Functional Linguistics treats cohesion as including relations such as repetition, synonymy and part–whole relations, with lexical chains helping to create textual continuity. Recent second-language research likewise notes that lexical overlap across sentences can help readers and listeners track conceptual relationships and support comprehensibility.

The British Council’s C1 material on avoiding repetition also teaches several legitimate alternatives to exact repetition—reference words such as this, that, such, substitution such as do so, and synonyms. The advanced lesson is therefore not “repeat everything” or “never repeat”. It is:

Use the cohesive device that preserves the concept most clearly.

选择那个最能让概念保持清楚、稳定、连续的衔接方式。

This lesson owns the Mandarin-supported C1–C2 route for lexical cohesion, controlled repetition and vocabulary chains. It does not replace Lesson No.006 on near-synonym precision, Lesson No.017 on paraphrase, Lesson No.018 on sentence frames, or general grammar owners for pronouns/reference. Here the learner problem is narrower: how vocabulary choices connect one sentence to the next without semantic drift.

---

1. Cohesion is not the same as coherence | cohesion 与 coherence 要分开

Cohesion concerns visible linguistic ties that connect parts of a text: repeated vocabulary, reference, substitution, conjunction and related lexical items. Coherence concerns whether the ideas form an understandable whole.

A paragraph can contain many connectors and repeated words yet still make no logical sense. It can also be conceptually coherent while using weak textual signals that make the reader work too hard.

词汇衔接是“线”；逻辑连贯是“图”。线可以帮助读者看见图，但线本身不能替你完成思考。

2. Lexical cohesion begins with recurrence | 词汇衔接的核心之一：关键概念会再次出现

Consider:

The study examined retrieval practice. This form of retrieval required learners to produce the target words without seeing them. Repeated retrieval was associated with better later recall.

The repeated root creates continuity. The reader never has to wonder whether a new concept has been introduced.

重复在这里不是“词穷”，而是在维护主题。

3. Exact repetition can be the clearest choice | 完全重复，有时就是最佳选择

Technical terms, defined concepts and core argument nouns often deserve exact repetition:

• working memory;
• retrieval practice;
• statistical significance;
• liquidity;
• latency;
• formative assessment;
• the intervention;
• the control group.

Replacing them merely to create lexical variety can create conceptual instability.

4. Technical terminology rewards consistency | 专业术语尤其需要一致性

If a report defines response time, do not later call the same measure reaction speed, latency and processing pace unless those terms genuinely mean the same thing in your field.

Terminological consistency reduces the reader’s cognitive load.

术语重复常常是专业精确，而不是写作失败。

5. Repetition can signal topic continuity | 重复可以告诉读者：我们还在谈同一件事

Paragraph:

The assessment measured vocabulary recall after one week. The assessment also included a transfer task. Results from the assessment were compared across groups.

This is highly repetitive but perfectly clear. Depending on style, one occurrence might later be replaced by it or the task, but there is no requirement to avoid all repetition.

6. Repetition becomes a problem when it adds no structure | 什么时候重复才真的变笨重？

Weak:

The method is useful because the method helps learners. The method also helps teachers because the method gives teachers information.

Here the repetition is not protecting a technical concept; it reflects undeveloped sentence structure.

Clearer:

The method helps learners practise retrieval while giving teachers useful diagnostic information.

7. Ask what the repeated word is doing | 不要数重复次数，要问它为什么重复

• Is it a technical term?
• Is it the paragraph topic?
• Is it needed to avoid ambiguity?
• Is it contrasting two uses of the same concept?
• Is repetition helping a new reader track the argument?
• Or is the sentence structure simply undeveloped?

This diagnostic is more useful than a rule such as “never use the same word twice in one paragraph”.

8. Lexical chains connect related vocabulary | Lexical chains：词汇链把相关概念串起来

A lexical chain is a sequence of semantically related items across a text.

Example topic: learning.

• learner;
• practice;
• retrieval;
• recall;
• memory;
• feedback;
• transfer.

These words are not synonyms. They form a semantic field that helps maintain the topic.

9. A chain can use repetition | 词汇链可以直接重复

• evidence → evidence → evidence;
• risk → risk → risk;
• assessment → assessment → assessment.

Exact repetition is the simplest cohesive link.

10. A chain can use synonymy and near-synonymy | 词汇链也可以用同义与近义关系

• problem → issue → difficulty;
• change → shift → alteration;
• show → indicate → suggest, only where stance permits.

Near-synonymy requires semantic control. Lesson No.006 applies directly.

11. A chain can use superordinate and subordinate terms | 上义词与下义词也能建立衔接

Example:

The study compared dogs and wolves. These animals differed in…

Animals is the superordinate term.

Academic example:

The experiment measured accuracy, speed and retention. These outcomes were then compared across conditions.

12. A chain can use part–whole relations | 部分—整体关系也能维持主题

• system → module → component;
• book → chapter → section;
• school → department → class;
• portfolio → asset → position.

These are not synonyms. Their relationship still creates cohesion.

13. A chain can use cause–effect vocabulary | 因果网络也会形成词汇链

• delay → bottleneck → reduced throughput;
• error → failure → recovery;
• practice → retrieval → retention.

The chain remains coherent because the concepts belong to one causal system.

14. A chain can use category vocabulary | 分类词也能成为段落骨架

Example:

• risk → credit risk → liquidity risk → operational risk;
• assessment → formative assessment → summative assessment → diagnostic assessment.

Repeated headwords can make category structure visible.

15. Reference chains reduce unnecessary noun repetition | 指代链可以减少机械重复

British Council C1 materials highlight devices such as it, this, that, these, those, such and do so for avoiding unnecessary repetition.

Example:

The study introduced a new feedback protocol. This protocol required teachers to identify the first error before correcting later errors. It was tested for six weeks.

The chain is: a new feedback protocol → this protocol → it.

16. Reference works only when the antecedent is clear | 指代省词之前，先确保读者知道它指什么

Ambiguous:

The teacher discussed the report with the parent after the student revised it. This was useful.

What was useful—the discussion, the revision or the report?

Repair:

The teacher then discussed the revised report with the parent. This discussion clarified the next steps.

17. “This + noun” is often stronger than bare “this” | this 后面加一个名词，常常更清楚

• this finding;
• this pattern;
• this difference;
• this limitation;
• this decision;
• this interpretation.

The noun tells the reader how to classify the previous information.

18. “Such” can refer back to a type | such 可以回指“这种类型”

Example:

The method requires learners to retrieve words without prompts. Such practice can be demanding at first.

Such practice classifies the previous activity as a type of practice.

19. “Do so” avoids repeating an action | do so 可以替代已经清楚的动作

Example:

Some teams reviewed the data weekly, while others did so only at the end of the month.

The action remains recoverable.

20. Substitution should reduce repetition without reducing clarity | 替代的目标是省重复，不是制造猜谜

If the reader must stop and search three sentences backward to discover what it or do so means, exact repetition may be better.

21. Synonym variation can create false progression | 同义词变化有时会让读者误以为概念在变化

Consider:

The problem affects three groups. This issue is difficult to measure. The challenge may become more severe.

Are these three names for one stable phenomenon, or has the writer changed perspective? Sometimes that variation is acceptable. Sometimes exact repetition is clearer.

22. Synonyms may differ in stance | 同义变化可能偷偷改变立场

• evidence → proof;
• claim → fact;
• problem → crisis;
• change → improvement;
• difference → discrepancy.

Each replacement adds or changes meaning.

Lesson No.020’s stance audit applies directly to lexical cohesion.

23. Synonyms may differ in scope | 同义变化也可能改变范围

• students → learners;
• employees → workers;
• schools → institutions;
• English vocabulary → language ability.

Broader terms can silently generalise the argument.

24. Synonyms may differ in register | 同义词也会把文章带到不同语域

• kids / children;
• buy / purchase;
• help / facilitate;
• use / utilise.

Do not rotate across registers merely for variation.

25. Synonyms may differ in collocation | 意思接近，搭配也可能完全不同

• strong evidence;
• compelling evidence;
• conclusive proof;
• firm conclusion;
• heavy workload;
• high demand.

Thesaurus replacement frequently fails because it ignores collocation.

26. Use a thesaurus for candidates, not answers | Thesaurus 只能提供候选词，不能直接给答案

1. Identify intended meaning.
2. Generate candidates.
3. Check a learner dictionary.
4. Check collocation.
5. Check stance/register.
6. Use corpus evidence if needed.

Lesson No.009’s verification workflow should follow any risky thesaurus substitution.

27. “Avoid repetition” is a local editing goal, not a global law | “避免重复”只是一种局部编辑原则

The British Council rightly teaches ways to avoid unnecessary repetition, including synonyms and reference devices. The advanced extension is to distinguish unnecessary repetition from necessary conceptual recurrence.

If a key term carries exact technical meaning, repeating it may be the more sophisticated choice.

28. Cohesion can be local | Local cohesion：相邻句之间要接得上

Recent Cambridge research distinguishes local, global and text-wide cohesion. Local cohesion concerns links within nearby sentences.

Example:

The experiment measured retrieval accuracy. Accuracy was highest after immediate feedback.

The overlap makes the connection effortless.

29. Cohesion can be global | Global cohesion：段落与段落之间也要保持概念线

A long article may introduce retrieval accuracy in one section and return to it several paragraphs later. Reusing the same term signals that the earlier concept has returned.

Global cohesion often requires more exact repetition than local prose because the reader’s memory needs stronger cues.

30. Cohesion can be text-wide | Text-wide cohesion：全篇需要稳定的关键词系统

In a long report, recurring anchor terms—risk, evidence, implementation, reliability—create a conceptual map.

If each anchor is constantly renamed, text-wide cohesion weakens.

31. Build paragraph anchor words | 每个段落选 1–3 个锚点词

A paragraph about assessment may anchor around:

• assessment;
• evidence;
• feedback.

Most other vocabulary should connect to those anchors.

32. Anchor words should survive revision | 修改时，不要把锚点词全部“优化掉”

Many learners perform a final “synonym sweep” and replace repeated anchor terms. This can damage the paragraph’s internal map.

Instead, highlight key terms before editing. Protect them unless repetition is genuinely awkward.

33. Build lexical-chain diagrams | 给长段落画“词汇链图”

Example chain:

evidence → finding → result → observation → evidence

Ask whether each link really belongs to the same chain. A result is not always evidence; an observation may be evidence for one claim but not another.

34. Build category chains | 分类文章特别适合用重复头词

Example:

• credit risk;
• liquidity risk;
• operational risk;
• reputational risk.

Repeating risk makes the category relation visible immediately.

35. Build contrast chains | 对比段落也需要稳定重复

Example:

Accuracy concerns closeness to the target. Precision concerns consistency or fineness, depending on the field. High precision does not guarantee high accuracy.

Repeating both terms protects the contrast.

36. Pronouns are dangerous in contrast paragraphs | 对比两个对象时，it / they 很容易让读者迷路

Weak:

Accuracy differs from precision because it focuses on closeness while it focuses on consistency.

Which it refers to which term?

Clearer:

Accuracy focuses on closeness to the target, whereas precision focuses on consistency.

Exact repetition is safer than ambiguous reference.

37. Repetition can protect scope | 重复名词有时能守住范围

Compare:

• The students in Group A improved. These students had received extra feedback.
• The students in Group A improved. Learners had received extra feedback.

The second version may accidentally broaden the claim to learners generally.

38. Repetition can protect causality | 重复也能防止因果对象换掉

If Sentence 1 identifies processing delay as a factor, Sentence 2 should not casually replace it with system failure unless failure is genuinely the same phenomenon.

39. Repetition can protect stance | 立场词周围的核心名词也需要稳定

Original:

The evidence is limited. This evidence may suggest a short-term effect.

Unsafe variation:

The evidence is limited. This proof demonstrates a short-term effect.

Both the noun and the reporting verb have strengthened.

40. Repetition can support teaching | 教学文本里，必要重复常常比成人文学写作更重要

Novice readers benefit from stable terminology. A teaching text that constantly varies labels can increase unnecessary vocabulary load.

World-class explanation is not measured by synonym density. It is measured by how reliably the reader can build the concept.

41. Audience affects repetition tolerance | 不同读者，需要不同程度的关键词重复

• Beginner reader → more exact recurrence may help.
• Expert reader → more compressed reference may be safe.
• Technical document → terminology consistency is high priority.
• Literary prose → stylistic variation may have greater value.

There is no universal optimum repetition rate.

42. Genre affects lexical cohesion | 文体会改变衔接策略

A scientific report may repeat technical terms frequently. A persuasive essay may use a broader lexical field. A meeting summary may repeat project names and responsibilities to avoid ambiguity.

Genre controls what counts as useful variation.

43. Spoken cohesion needs stronger audible cues | 口语没有回看按钮，因此关键概念往往需要更明显地回收

In speech, listeners cannot easily scan backward. Repeating or restating the topic can help:

“The main issue is timing. And when I say timing, I mean the delay between feedback and revision.”

Exact repetition can be a listening aid.

44. Writing allows denser reference—but ambiguity remains possible | 写作可以更压缩，但不能让指代变模糊

Written readers can reread, yet dense pronoun chains still increase processing cost. Use this finding, this difference, this method when classification helps.

45. Topic sentences should seed lexical chains | 主题句最好播下本段的核心词

Topic sentence:

Feedback timing influences how learners use corrections.

Later chain:

• immediate feedback;
• delayed feedback;
• timing;
• correction;
• revision.

The paragraph develops from the lexical field introduced at the start.

46. Conclusion sentences should close the lexical chain | 段尾可以回收关键词，让读者知道这一段完成了什么

Overall, the evidence suggests that feedback timing matters most when learners must revise independently.

Returning to the anchor term creates closure.

47. Paragraph transitions can bridge two lexical fields | 段落过渡句可以同时抓住旧词与新词

Example:

Although feedback timing affects revision, the usefulness of that feedback also depends on its specificity.

The sentence closes one chain and opens the next.

48. Build lexical bridges between sections | 长文每一节不要像重新开始

At the start of a new section, briefly recover the prior concept:

The previous section showed how timing affects feedback use. We now examine a second factor: feedback specificity.

The text’s conceptual map remains visible.

49. Avoid “synonym storms” | 同义词风暴：同一个概念每句换名字

Weak:

The policy was introduced in May. The initiative affected three schools. The scheme required weekly reports. The programme was reviewed in July.

Are these four nouns truly interchangeable? Perhaps. Perhaps not.

Clearer if they refer to one thing:

The policy was introduced in May. It affected three schools and required weekly reports. The policy was reviewed in July.

50. Avoid “pronoun fog” | 另一种极端：全部换成 it / this / they

Weak:

The policy affected the school and the department. It changed it because they had to revise it.

Reference economy has destroyed clarity.

Repeat the nouns that matter.

51. Avoid “category drift” | 上义词用得太宽，也会让主题漂移

If Sentence 1 discusses primary school teachers, replacing them with professionals may broaden the category too far.

Use superordinates only when the broader category is actually intended.

52. Avoid “metaphor drift” | 比喻变化也可能破坏词汇链

Paragraph:

The idea gained traction. It then took root. Finally, the proposal crossed the finish line.

Tyre grip → plant growth → race. The meaning may survive, but the lexical field becomes noisy.

Lesson No.012’s metaphor-coherence rule applies.

53. Avoid “keyword stuffing” too | 重复可以衔接，但不能为了 SEO 或考试机械塞关键词

Useful repetition follows conceptual need. Mechanical repetition that sounds unnatural reduces readability.

The test is semantic: does the repeated word help identify the same concept, or is it being inserted without discourse need?

54. Lexical cohesion is not a vocabulary-score trick | 不要把词汇衔接降级成“考试同义替换技巧”

Tests may reward lexical range, but real-world writing must first preserve meaning and coherence. A synonym that increases variety but weakens precision is not an upgrade.

55. Build a repetition map during revision | 修改时画“重复地图”

1. Highlight repeated content words.
2. Mark technical/anchor terms in one colour mentally or on paper.
3. Protect necessary recurrence.
4. Circle mechanical repetition caused by weak syntax.
5. Replace only where reference, restructuring or safe synonymy improves clarity.

Do not begin by deleting repetition. Begin by classifying it.

56. Build a lexical-chain map during revision | 再画“词汇链地图”

For each paragraph, list the major chain:

feedback → correction → revision → learner response → feedback

Ask whether the chain reflects the paragraph’s intended concept or wanders into unrelated vocabulary.

57. Build “same concept?” checks | 每一次换词，都问一句：还是同一个概念吗？

• evidence → proof: same?
• student → learner: same?
• policy → programme: same?
• result → finding: same?
• problem → limitation: same?

If not perfectly, decide whether the semantic shift is intentional.

58. Build “same referent?” checks | 指代替代时，再问：还是同一个对象吗？

• the intervention → this programme;
• the sample → these participants;
• the findings → these results;
• the policy → the measure.

Some substitutions narrow or broaden the referent.

59. Build “same stance?” checks | 再问：换词以后立场变了吗？

• issue → crisis;
• difference → discrepancy;
• claim → fact;
• evidence → proof;
• change → improvement.

Lexical cohesion and stance control intersect constantly.

60. Build “same register?” checks | 同义替换也要检查语域一致性

• kids → children;
• buy → purchase;
• help → facilitate;
• show → demonstrate.

A paragraph that jumps repeatedly between conversational and bureaucratic vocabulary can feel unstable.

61. Worked case: Maren removes every repeated word | 案例一：Maren 做“同义词扫荡”

Maren writes:

The assessment measured retrieval after one week. The assessment also included a transfer task. The assessment therefore provided two kinds of evidence.

She dislikes the repetition and revises:

The assessment measured retrieval after one week. The test also included a transfer task. The evaluation therefore provided two kinds of evidence.

Now three labels may imply three different instruments or processes.

Better:

The assessment measured retrieval after one week and also included a transfer task. It therefore provided two kinds of evidence.

中文分析：真正的问题不是 assessment 重复，而是原句可以通过句法合并减少机械重复。术语本身不需要乱换。

62. Worked case: Iona uses pronouns until reference collapses | 案例二：Iona 为了不重复，把名词全换成 it

Iona writes about two explanations:

The timing explanation differs from the motivation explanation because it accounts for the delay whereas it does not explain the later recovery.

The pronouns are unrecoverable.

Repair:

The timing explanation accounts for the initial delay, whereas the motivation explanation better explains the later recovery.

Repeating the labels improves contrast.

63. Worked case: Leonie changes one term mid-meeting | 案例三：Leonie 在会议里随手换词，团队以为出现新概念

The team has defined deployment risk. Leonie later says implementation uncertainty because she wants variety. A colleague asks whether she means the same risk category or a new one.

Leonie learns a professional rule: once a team agrees on a defined term, repeat it consistently unless you deliberately redefine the concept.

中文分析：在专业环境里，词汇一致性本身就是协作效率。

64. Worked case: lexical overlap helps a difficult explanation | 案例四：重复让复杂解释变容易

Original dense version:

Measurement precision affects the reliability of repeated estimates. Greater consistency across repeated estimates can therefore improve confidence in measurement stability.

The lexical overlap—repeated estimates, consistency, measurement—helps the reader connect the two sentences.

Removing all overlap would force the reader to rebuild the relation from scratch.

65. The FENCE lexical-cohesion system | FENCE 词汇衔接系统

Fence	Question	Action
F0 Anchor	What concept must remain stable?	identify key term
F1 Recurrence	Should I repeat exactly?	protect terminology
F2 Reference	Can I use it/this/such safely?	check antecedent
F3 Relation	Can related vocabulary extend the chain?	synonym/category/part-whole
F4 Meaning	Does the substitute mean the same thing?	semantic audit
F5 Stance	Did evaluation/claim strength change?	stance audit
F6 Register	Does the replacement fit the same genre?	register audit
F7 Span	Local, paragraph or text-wide chain?	restore global anchors
F8 Readability	Does the reader track the concept easily?	final cohesion pass

66. Build an anchor-term card | 建立“锚点词卡”

Field	Example
Anchor term	retrieval practice
Exact repetition allowed?	yes, defined technical concept
Safe shorter reference	retrieval / this practice, where clear
Related chain	recall, memory, testing, practice
Unsafe substitute	revision, recognition, memorisation if meaning differs
Paragraph role	central topic

67. Build “repeat / refer / replace” decisions | 每次重复都只有三个主要选项

• Repeat — when terminology or contrast must stay explicit.
• Refer — when the referent is unmistakable.
• Replace — when a genuine semantic relation improves flow without changing meaning.

Do not add a fourth option called “random thesaurus word”.

68. Build “same concept across five sentences” drills | 练同一概念跨五句保持稳定

Target: feedback.

• Sentence 1: define feedback.
• Sentence 2: refer to it with this feedback.
• Sentence 3: introduce immediate feedback.
• Sentence 4: contrast with delayed feedback.
• Sentence 5: return to feedback timing.

This trains controlled lexical development.

69. Build “lexical chain from topic sentence” drills | 从主题句生成词汇链

Topic: implementation risk.

Possible chain:

implementation risk → constraint → failure point → mitigation → monitoring → residual risk

Then write a paragraph that uses the chain naturally.

70. Build “bad synonym substitution” drills | 专门练“这个同义词为什么不能换”

• evidence → proof;
• finding → fact;
• problem → crisis;
• change → improvement;
• student → learner;
• policy → programme.

For each pair, state what semantic dimension changes.

71. Build “reference repair” drills | 练习把模糊 it / this 修成清楚链

Weak:

The method changed the schedule and the feedback process. This improved it.

Possible repair:

The method changed both the schedule and the feedback process. The revised feedback process improved response time.

The noun resolves ambiguity.

72. Build “global anchor recovery” drills | 长文里每隔几段重新叫回锚点

If a section has used pronouns and subcategories for several paragraphs, repeat the full anchor term at a transition:

These patterns suggest that retrieval practice is most effective when learners must reconstruct the target without strong cues.

This refreshes the reader’s conceptual map.

73. A 20-minute lexical-cohesion session | 20 分钟词汇衔接训练

Time	Task
0–5 min	Choose one paragraph and highlight repeated content words.

24–30 min	Find unsafe synonym substitutions.
30–35 min	Repair ambiguous reference chains.
35–40 min	Restore full anchor terms at key transitions.
40–45 min	Read for coherence after cohesion edits.

75. A seven-day cohesion challenge | 七天词汇衔接挑战

Day	Focus
1	exact repetition and anchor terms
2	reference chains: this/it/such
3	synonym and near-synonym safety
4	superordinate/subordinate relations
5	lexical chains across paragraphs

76. A 30-day lexical-cohesion challenge | 30 天词汇衔接升级

• Audit 20 paragraphs for anchor terms.
• Build 30 lexical-chain maps.
• Repair 30 unsafe synonym substitutions.
• Repair 20 ambiguous pronoun/reference chains.
• Write 10 contrast paragraphs using deliberate repetition.
• Write 10 technical paragraphs with terminology consistency.
• Complete five spoken explanations using audible topic recurrence.
• Complete four text-wide anchor recovery exercises.

The target is not lower repetition. The target is higher conceptual continuity.

77. A 12-week progression | 12 周词汇衔接路线

Weeks	Focus	Evidence of progress
1–2	anchor-term identification	less unnecessary synonym replacement
3–4	reference chains	fewer ambiguous pronouns
5–6	lexical fields and chains	stronger paragraph continuity
7–8	technical terminology consistency	less concept drift
9–10	global/text-wide cohesion	long texts easier to track
11–12	genre/audience adaptation	repetition calibrated to reader and task

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

Symptom	Likely first weak link	Repair
I replace every repeated word.	repetition misconception	protect anchor terms
My terminology changes across pages.	term consistency	canonical term list
My paragraphs use too many it/this/they.	reference clarity	restore classification nouns
My writing feels repetitive but terms must stay.	sentence structure	combine/restructure, not synonymise
My synonyms subtly change the claim.	semantic boundary	Lesson 006/020 audit
Each sentence seems separate.	lexical chain weakness	map shared field/anchors
Long sections lose the main topic.	global cohesion	repeat full anchor at transitions
I use technical repetition in casual speech.	register/audience	spoken restatement + reference balance

79. Practice A — repeat, refer or replace? | 练习 A：重复、指代还是换词？

1. A technical term defined as “working memory” appears again two sentences later.
2. The noun “assessment” appears three times in one sentence.
3. Two competing explanations must be contrasted.
4. A clearly identified method is mentioned in the next sentence.
5. The writer wants to replace “evidence” with “proof” only to avoid repetition.
6. A list of accuracy, speed and retention is referred to collectively.

80. Practice B — repair lexical drift | 练习 B：修复换词造成的漂移

7. The evidence is limited. This proof shows that the method works.
8. The students in Group A improved. These learners received more feedback.
9. The policy was introduced in May. The programme was reviewed in July. Intended meaning: same policy.
10. The study found a difference. This discrepancy proves the groups are unequal.
11. The intervention produced a change. This improvement lasted one week. Original text did not say change was positive.

81. Practice C — build lexical chains | 练习 C：给主题建词汇链

12. retrieval practice;
13. risk management;
14. feedback timing;
15. measurement reliability;
16. implementation failure.

For each, create a 6–8 item chain containing at least one exact repetition, one category relation and one causal/functional neighbour.

82. Practice D — repair reference ambiguity | 练习 D：修复指代模糊

17. The policy changed the timetable and the assessment. This affected it.
18. The researcher compared accuracy with precision because it was lower.
19. The teacher discussed the essay with the student after the parent read it. This was useful.
20. The system contains a controller and a backup unit. It failed first.

83. Practice E — protect a technical term | 练习 E：不要为了“多样性”破坏术语一致

Rewrite this paragraph so that formative assessment remains the stable term while mechanical repetition is reduced through syntax/reference:

Formative assessment happens during learning. Formative assessment gives teachers information. Formative assessment can change the next lesson. Formative assessment can also help students understand their errors.

84. Answers A | 练习 A 参考

1. Repeat is often safest for a defined technical term.
2. Restructure or use clear reference; do not automatically synonymise.
3. Repeat the explanation labels to protect contrast.
4. Refer with it/this method if unambiguous.
5. Do not replace. Proof changes claim strength.
6. Use a safe superordinate such as these outcomes/measures if appropriate.

85. Answers B — model repairs | 练习 B 参考

7. The evidence is limited. This evidence may suggest that the method works under the observed conditions.
8. The students in Group A improved. These students received more feedback.
9. The policy was introduced in May. It was reviewed in July.
10. The study found a difference. This difference requires further explanation. Do not add “proves unequal” without evidence.
11. The intervention produced a change. This change lasted one week. Call it an improvement only if positive direction is established.

86. Answer D — model repairs | 练习 D 参考

17. The policy changed both the timetable and the assessment. The revised timetable affected lesson scheduling.
18. The researcher compared accuracy with precision because accuracy was lower.
19. After the parent read the essay, the teacher discussed it with the student. The discussion clarified the next revision step.
20. The system contains a controller and a backup unit. The controller failed first.

87. Answer E — model paragraph | 练习 E 参考

Formative assessment takes place during learning and gives teachers information they can use to adjust the next lesson. This assessment can also help students understand their errors and decide what to improve next.

The technical term remains stable; sentence structure and reference reduce mechanical repetition.

88. How a strong tutor teaches lexical cohesion | 高水平导师怎样教词汇衔接？

A weak lesson circles repeated words and says “find synonyms”. A strong lesson asks:

• Which term is the conceptual anchor?
• Which repetition is necessary?
• Which repetition comes from weak syntax?
• Can reference reduce repetition safely?
• Does the proposed synonym preserve meaning?
• Does the substitute change stance or scope?
• Which related terms form the lexical field?
• Can the reader still track the concept across the paragraph?

The tutor teaches text-building, not synonym decoration.

89. The learner should become their own cohesion editor | 最终，学生要成为自己的“词汇衔接编辑”

During revision, ask:

• What are my three main anchor terms?
• Have I renamed one concept unnecessarily?
• Is any pronoun ambiguous?
• Can I combine sentences instead of changing terminology?
• Does every synonym preserve stance and scope?
• Do my paragraph chains connect to the topic sentence?
• Do section transitions recover earlier anchor terms?
• Would a new reader know which concept I am still discussing?

This editor protects both lexical range and conceptual stability.

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

This lesson owns the Mandarin-supported C1–C2 route for lexical cohesion, controlled repetition, lexical chains and terminology continuity. It coordinates but does not replace:

• Lesson No.006 — near-synonym precision.
• Lesson No.009 — corpus evidence.
• Lesson No.017 — meaning-preserving paraphrase.
• Lesson No.018 — lexical bundles and sentence frames.
• Lesson No.020 — stance and claim calibration.

91. Recommended reference floor | 推荐参考资源

• Cambridge — About Language: Cohesion — lexical and grammatical devices that bind sentences into text.
• The Cambridge Handbook of Systemic Functional Linguistics — Cohesion and Conjunction — cohesion through reference, synonymy, part–whole relations, conjunction and lexical chains.
• British Council LearnEnglish C1 — Avoiding Repetition in a Text — reference words, substitution, do so and synonymy.
• Cambridge — Coherence and Comprehensibility in L2 Academic Speaking — evidence on lexical overlap, repetition and discourse comprehensibility.
• Cambridge — Linguistic Complexity and CEFR Text Difficulty — local, global and overall cohesion, including content-word repetition.
• Oxford Advanced Learner’s Dictionary — sense, register and collocation checks before synonym substitution.

93. Your assignment | 本课作业

Take one 600–1,000 word piece of your own English.

1. Highlight the five most repeated content words.
2. Decide which are true anchor terms.
3. Protect exact repetition of technical terms where needed.
4. Find five repetitions caused by weak sentence structure and repair them without unsafe synonymy.
5. Find every it, this, that, they, such and check the antecedent.
6. Change bare this to this + noun where classification improves clarity.
7. Find five synonym substitutions and test meaning, stance, scope, register and collocation.
8. Draw one lexical-chain map per paragraph.
9. Check that the first and last sentence of each paragraph connect to the same conceptual field.
10. At every section transition, decide whether a full anchor term should be repeated.

Then perform one final experiment: replace every repeated anchor term with a different synonym. Read the text. If clarity drops or the concepts begin to drift, restore the stable terms. The exercise teaches why repetition can be a feature rather than a flaw.

不要问：“这一段有没有重复？”要问：“这一段的重复，是在浪费语言，还是在保护概念？”

94. The final rule | 最后一条规则

Repeat the concept when the concept must remain the same. Vary the language only when the meaning can safely move.

概念必须保持相同时，就让关键词重复。只有意义可以安全移动时，才让语言变化。

A sophisticated vocabulary does not panic when a key word appears twice. It knows the difference between tedious repetition and cohesive recurrence.

Repeat working memory because it is the defined concept. Repeat accuracy and precision because the contrast depends on stable labels. Use this finding when the reader can safely recover the previous result. Use a near-synonym only when it preserves the intended relationship.

Lexical range gives you options. Lexical cohesion tells you when not to use them.

高级词汇不是“每句话换一个新词”。高级词汇是你拥有很多选择，却知道什么时候最好的选择仍然是刚才那个词。
