C1 Integrated Mastery: Control, Stance, and Flexibility

Integrate advanced grammar to analyse evidence, attribute positions, organise information, adapt register, and repair language during a complete real-world performance.

Time30 minutes
SkillsIntegrated grammar + Professional communication
OutcomeA controlled evidence-based decision briefing

Integrated C1 grammar control

UseSelect and combine C1 structures according to meaning, evidence, information focus, source stance, audience, cohesion, and interpersonal purpose.
Core formaspect and viewpoint · modal and claim calibration · voice and information structure · cohesion and clause reduction
Flexible controlnominal and noun-phrase packaging · reporting stance · connectors · register shift · ambiguity repair
RememberMastery is not the number of advanced structures used; choose the least complex form that expresses the intended relationship precisely, then monitor and repair it independently.

Your goal

By the end of this lesson, you can plan from meaning, select structures from six C1 systems, deliver a three-minute decision briefing, adapt one section for another audience, and repair two weaknesses independently.

Your grammar path

MeaningBuild the decision model

Define evidence, source positions, uncertainty, responsible actors, alternatives, audience, and required decision before choosing grammar.

PatternSelect from connected C1 systems

Choose only the aspect, stance, focus, cohesion, information-packaging, and register structures that serve each part of the message.

UsePerform, adapt, and self-repair

Deliver the briefing, answer a challenge, reformulate one section for a different audience, and repair two weaknesses using evidence from listener response.

1 · Build the decision map

Plan meaning before language

C1 integrated grammar control map for meaning evidence stance information focus cohesion register and repair
Use the visual to notice, practise, and communicate.

Record evidence, source positions, uncertainty, actors, alternatives, audience, and the decision required.

How to run Stage 1

4 min: Build the meaning, evidence, actor, and audience decision map.

2 · Select C1 systems

Use complexity only where it adds precision

Choose structures from at least six systems and explain the meaning or discourse job of each choice.

How to run Stage 2

5 min: Select C1 structures and justify their functions.

3 · Rehearse control

Check stance, cohesion, focus, and ambiguity

Engduo Audio: Listen for meaning first. Audio never starts automatically.

Engduo Audio • British English

Identify viewpoint, reporting stance, calibration, condition, focus, connector, nominalisation, and responsibility.

Engduo Audio • American English

Compare register and structure while checking which facts, stance, condition, and action remain constant.

Run a ninety-second draft, remove one unnecessary complex structure, and repair one unclear reference or scope.

How to run Stage 3

4 min: Rehearse stance, cohesion, focus, and ambiguity control.

4 · Listen and critique

Compare two valid register solutions

Listen to both briefings, identify the systems used, and verify which meaning remains constant across the audience shift.

How to run Stage 4

5 min: Play both briefings and critique the audience shift.

5 · Communicate

Deliver, adapt, and self-repair

Give a three-minute decision briefing, answer one evidence challenge, adapt one section for a different audience, and repair two weaknesses independently.

How to run Stage 5

8 min: Run the decision briefing, challenge response, and reformulation.

Final practice: Choose, control, adapt, and repair C1 grammar

Task: Deliver a three-minute evidence-based decision briefing, answer a challenge, reformulate one section for another audience, and make two evidence-based self-repairs.

Success: Structures serve meaning rather than display complexity, evidence and stance are calibrated, information flow and register fit the audience, and self-repairs improve accuracy and clarity.

LC · Language Control

0 Frequent form problems obscure the intended meaning.

1 Meaning remains clear with some prompting or self-correction.

2 Selects and controls C1 grammar across viewpoint, stance, focus, cohesion, information packaging, register, and ambiguity repair.

FP · Functional Performance

0 Does not yet complete the communication outcome.

1 Completes most of the outcome with visible prompts.

2 Delivers, adapts, defends, and independently repairs a sustained C1 decision briefing with flexible audience-aware control.

How to run Stage 6

4 min: Score LC and FP, complete two self-repairs, and retry the weakest section.
