C2-Direction Review and Expert Communication | C2 方向复习与专家沟通

Expert communication is not simply difficult English. It is unusually stable control over meaning, evidence, audience, nuance, structure and repair.

This lesson consolidates the C2-direction system developed through Lessons 085–091. It is a performance checkpoint, not formal certification.

这一课检查的是：面对陌生领域、冲突证据、不同受众和实时质疑时，能不能继续保持高度精确、清晰、可修复的英语。

The expert-communication map | 专家沟通地图

semantic precision
evidence literacy
cross-disciplinary synthesis
figurative precision
audience adaptation
register switching
pragmatic nuance
advanced editing
real-time reformulation
independent judgement

1. Performance before labels | 表现优先

Ask:

Can the learner preserve precision while the content, audience and evidence all change?

2. C2-direction does not mean perfect | C2 方向不等于零错误

High-level users still make errors. The difference is that errors are usually local, noticed, repairable and do not destabilise the whole message.

3. Semantic precision checkpoint | 语义精度检查

Can you distinguish and use appropriately:

possible / plausible / probable / likely
effect / impact / consequence / outcome
claim / argument / finding / inference
issue / problem / concern / risk

4. Collocation checkpoint | 搭配检查

Can you choose natural combinations without translating word-by-word?

compelling evidence
draw a distinction
raise a concern
account for a difference
reach a conclusion

5. Lexical restraint checkpoint | 词汇克制

Can you choose a common word when it is more exact than a rare one?

6. Evidence-literacy checkpoint | 证据素养检查

Can you separate:

sample from population
measurement from construct
association from causation
statistical detection from practical importance
internal validity from generalisability

7. Method-to-claim checkpoint | 方法→主张检查

9. Source-weighting checkpoint | 来源权衡检查

Can you explain why one source deserves more weight for one sub-question and less for another?

10. Cross-disciplinary checkpoint | 跨学科检查

Can you identify:

shared question
different definitions
different methods
different scale
transferable mechanism
non-transferable features

11. Avoid false equivalence | 避免错误等同

Similar words or patterns across fields do not guarantee the same mechanism.

12. Figurative-language checkpoint | 修辞语言检查

Can you use metaphor or analogy to clarify without importing false relationships?

13. State analogy limits | 说出类比边界

This comparison helps explain X, but it does not imply Y.

14. Return to literal mechanism | 回到字面机制

After a figurative explanation, can you state the actual process directly?

15. Audience checkpoint | 受众检查

Can you explain the same evidence to:

a young learner
a general adult audience
a manager
a specialist

16. Meaning stability across audiences | 跨受众意思稳定

Terminology may change. The evidence and core proposition must not.

17. Register checkpoint | 语体检查

Can you switch smoothly among:

informal
neutral
professional
formal
technical
public-facing

18. Formality is not heaviness | 正式不等于沉重

Clear professional English often uses direct verbs and ordinary vocabulary.

19. Pragmatic checkpoint | 语用检查

Can you interpret:

indirect refusal
understatement
polite disagreement
possible irony
backchannels
reformulation

20. Inference calibration | 推断校准

Can you assign high, medium or low confidence to an interpretation and explain why?

21. Do not mind-read | 不读心

Describe the communicative effect before inferring motive.

22. Real-time reformulation | 实时改写

Can you respond immediately with:

simpler wording
more technical wording
narrower claim
different analogy
different evidence order

23. Repair language | 修复语言

Let me be more precise.
That’s too broad; I mean…
Let me separate two issues.
I’d qualify that point.

24. Discussion under challenge | 质疑下讨论

Can you remain accurate when someone:

changes the criterion
questions your source
offers counterevidence
asks for a simpler explanation

25. Expert disagreement | 专家式分歧

Name the level of disagreement:

definition
premise
method
evidence
inference
scope
value criterion

26. Mediation checkpoint | 调解表达检查

Can you summarise two positions fairly enough that both sides recognise themselves?

27. Real-time synthesis | 实时综合

It sounds as though both sides accept the data but disagree about which outcome should matter most.

28. Writing checkpoint | 写作检查

decision
evidence
risk
options
next action

37. Technical communication checkpoint | 技术沟通检查

Can you expand the same issue into method, assumptions, uncertainty and limitations?

38. Same core, different packaging | 同核心，不同包装

Expert communication changes packaging, not truth conditions.

39. Cross-domain transfer | 跨领域迁移

Can you perform on a topic outside your strongest domain?

40. Domain humility | 领域谦逊

Language mastery does not replace specialist knowledge. Know when to consult domain sources or experts.

41. Strategic tool use | 策略性工具使用

Use dictionaries, corpora, references and domain tools to verify what cannot safely be guessed.

42. Independence is not isolation | 独立不等于不用帮助

Expert independence includes knowing when external verification is necessary.

43. Unknown-term protocol | 陌生术语流程

identify domain
infer cautiously from context

67. First weak link map | 第一个弱点地图

Break	Return
semantic precision	085
method claims	086
audience adaptation	087
C1→C2 transfer	088
figurative precision	089
cross-disciplinary synthesis	090
advanced editing	091

68. Green / Amber / Red | 绿黄红

Green: meaning and evidence survive unfamiliarity, speed and audience shifts.
Amber: high quality with preparation, slower repair under pressure.
Red: source, meaning or audience control breaks.

69. Maintenance matters | 维持比继续堆知识更重要

At this stage, development increasingly comes from breadth, transfer and deliberate practice rather than collecting more isolated grammar.

70. Expert maintenance cycle | 专家维持循环

At this stage, stop using “more difficult vocabulary” as the main growth metric.

Measure transfer, repair, audience adaptation, source control and semantic precision.

For Mandarin speakers, evaluate whether high-level English is processed directly and flexibly rather than rebuilt through translation.

73. What Lessons 089–092 add | 第八十九至九十二课增加了什么？

Lesson	New control
089	metaphor, analogy and figurative precision
090	cross-disciplinary synthesis
091	meaning-first advanced editing
