Why this lesson matters
At C2, ellipsis often stretches across several turns, speakers and propositions. The risk is not simply missing grammar: a shortened reply can hide whether it accepts the same option, condition, scope or degree of commitment. Advanced cohesion keeps the entire decision trail recoverable.

Teacher Lesson Plan
Reconstruct each shortcut as a decision record: who commits to what, under which condition, with what polarity and scope? Accept compression only when another listener reconstructs the same record.
| Stage | Teacher move | Evidence to collect |
|---|---|---|
| 1 · Reconstruct | Restore ten advanced patterns. | 10 full propositions |
| 2 · Compare | Contrast seven compression options. | 7 justified choices |
| 3 · Trace | Map cohesion across a decision exchange. | 1 complete trail |
| 4 · Repair | Repair five unclear omissions. | 5 auditable repairs |
| 5 · Transfer | Audit two accent-varied exchanges. | 2 decision maps |
| 6 · Perform | Score MEAN/FORM/USE and target one retry. | Decision exchange + retry |
Stage 1 · Reconstruct ten elliptical patterns
Restore the full proposition, not just the nearest repeated verb.
STUDENT TASK
| Compressed line | Full reconstruction | What remains visible |
|---|---|---|
| The legal team approved it, but operations didn’t. | Operations did not approve it. | subject + auxiliary + polarity |
| We can launch in June, and perhaps in May. | Perhaps we can launch in May. | modal scope from first clause |
| The first option is safer than the second. | …than the second option is safe. | comparative frame |
| They may accept the revised limit; I hope so. | I hope they will accept the revised limit. | propositional substitute |
| If necessary, we can pause—and will. | We will pause if it is necessary. | condition + auxiliary commitment |
- Reconstruct ten shortened lines in full.
- Name the source turn and speaker.
- Restore polarity, modality, condition and scope.
- Reject a reconstruction that changes commitment.
- Explain which visible cue licenses the ellipsis.
Finish evidenceTen full reconstructions with source and commitment intact.
Teacher Help · Stage 1
Nearest-word recovery can be wrong when a dialogue contains several propositions. Ask learners to state the entire proposition and then identify the turn that supplies it.
Stage 2 · Compare seven compression options
Choose the shortest form that preserves the intended contrast and stance.
STUDENT TASK
| Option | Best use | Decision risk |
|---|---|---|
| auxiliary ellipsis | contrast subject, tense, modality or polarity | wrong source verb |
| coordinate ellipsis | share material across parallel clauses | scope attaches to only one clause |
| comparative ellipsis | avoid repeating the comparison frame | standard of comparison is hidden |
| so/not substitution | refer to a whole proposition | stance verb does not permit the form |
| one/ones | contrast members of one countable class | class or number unclear |
| summary noun | package an event or claim | the noun adds judgment |
| deliberate repetition | restore accountability after distance | heavier but sometimes necessary |
- Choose among seven options in fourteen contexts.
- State the full unreduced message.
- Name the focus or stance the short form preserves.
- Reject one shorter option because it hides scope or responsibility.
- Use deliberate repetition once to re-anchor the decision.
Finish evidenceSeven compression contrasts with decision-focused reasons.
Teacher Help · Stage 2
The “most advanced” answer is not always the shortest. At C2, controlled repetition is a strategic cohesion resource when distance, competing proposals or accountability make ellipsis unsafe.
Stage 3 · Trace cohesion across a decision exchange
Map how options, conditions and commitments move through several turns.
STUDENT TASK
Grammar lens · decision trail
| Turn | Compressed move | Recoverable record |
|---|---|---|
| 1 · Proposal | We could extend the pilot; finance might. | Finance might approve extending the pilot. |
| 2 · Condition | If the cap remains—and it must. | The cap must remain for approval. |
| 3 · Contrast | Operations prefers July; sales, August. | Sales prefers August. |
| 4 · Commitment | July, then. We’ll support it. | Both sides choose the July extension. |
- Map the proposal, condition, contrast and final commitment.
- Link each elliptical form to its source turn.
- Write actor, action, condition, modality and polarity.
- Identify one place where controlled repetition improves the record.
- Summarise the final decision in one explicit sentence.
Finish evidenceOne complete decision trail with no missing responsibility.
Teacher Help · Stage 3
Do not let learners map only vocabulary. Cohesion must preserve speech act and commitment: a suggestion, possibility, requirement and final agreement are not interchangeable.
Stage 4 · Repair five unclear omissions
Restore the minimum language needed to make the decision auditable.
STUDENT TASK
| Unclear line | Competing readings | Repair target |
|---|---|---|
| The vendor accepted the cap; finance may too. | may accept / may impose | Finance may accept it too. |
| We can shorten testing or support, but not both. | shorten both activities / choose both options | State what cannot be shortened together. |
| They expect the review to pass; we don’t. | do not expect / do not pass | Keep the stance verb. |
| The revised one is safer, though not necessarily. | not safer / not revised | Restore the adjective and degree. |
| If approved, we will proceed; if not, later. | proceed later / seek approval later | Name the fallback action. |
- State at least two plausible readings.
- Identify missing source, scope, stance or fallback.
- Restore the smallest decisive element.
- Ask a partner to repeat the operational decision.
- Keep revising until both records match.
Finish evidenceFive repairs with one shared decision record each.
Teacher Help · Stage 4
A repair is complete only when both listeners can state the same actor, action, condition and commitment. Grammatical acceptability alone is not enough.
Stage 5 · Listen across two accents and audit cohesion
Follow ellipsis across speakers without losing which proposal or condition is active.
STUDENT TASKAmerican English Australian English
Scope and fallback
Recover the scope of each shortened reply and the fallback action if the preferred option fails.
- Listen once and state the final decision.
- Listen again and map every shortened turn to its source.
- Record actor, action, condition, polarity and commitment.
- Identify one compression choice that is elegant and one that needs expansion.
- Replay only the turn where the decision trail breaks.
Finish evidenceTwo auditable decision maps and one targeted expansion.
Teacher Help · Stage 5
The accents test meaning transfer, not imitation. Ask learners to reconstruct the operational decision, not transcribe every word.
Stage 6 · Final Practice: concise decision exchange
Compress repeated material across several turns while keeping agreement and responsibility explicit.
STUDENT TASK
FINAL PRACTICE
Options → conditions → compressed exchange → audit → decision → retry
- Choose a complex decision with three options, two conditions and one fallback.
- Write a full decision record: actors · actions · stance · conditions · scope · fallback.
- Conduct a 2-minute exchange using at least four compression options.
- Use controlled repetition once to re-anchor responsibility.
- Your partner challenges: “Which proposal do you mean?” and “What exactly are you agreeing to?”
- Expand only the unclear element.
- Close with one explicit decision sentence and named owners.
- After one feedback target, retry the weakest three turns.
Performance rule: Advanced compression succeeds only when both speakers can reconstruct the same proposal, condition, scope and commitment.
Score the first independent performance
MEAN · MeaningEvery shortened turn preserves proposal, condition, polarity, scope and commitment.
FORM · FormEllipsis, substitution, reference and retained auxiliaries license one secure reconstruction.
USE · Real useThe exchange is concise, reaches a decision and leaves an auditable record of owners and fallback.
0 · Not yetAn omission creates competing decisions or hides responsibility.
1 · With supportThe decision becomes secure after one prompt or explicit repair.
2 · IndependentThe learner compresses flexibly, answers both challenges and repairs the weakest turns without a prompt.
Result: 0–2 Rebuild · 3–4 Developing · 5–6 C2 mastery evidence.
Finish evidenceOne concise decision exchange + one cohesion-focused retry.
Teacher Help · Stage 6
Score the first independent attempt across MEAN, FORM and USE. Give one target only: source proposition, scope, stance, retained auxiliary, re-anchoring or decision clarity. Keep the original score and record the retry separately.
