Choose a short recording.
Before you start
If one person says I have checked the figures, what can the next person say without repeating the entire phrase?
Useful background: B2 Ellipsis and Substitution 1; auxiliary verbs and perfect, progressive and modal forms.
Retain the auxiliary that fits
A recoverable verb phrase may be omitted after an auxiliary or modal. The retained form carries the relevant tense, aspect or modal meaning and must match what the new speaker intends.
Maya has checked the figures, and Noor has too.
I cannot attend on Tuesday, but I can on Friday.
Use do so for a recoverable action
Do so can substitute for an earlier action in suitable contexts, especially relatively formal prose. Its tense can change. It is not a universal replacement for every state or any arbitrary noun phrase.
We asked them to revise the heading, and they did so.
Anyone wishing to comment should do so before Friday.
Recover the same action, keep its new time
Did so recovers responded and locates the response in the past.
Will do so recovers respond, while tomorrow gives the new time.
Keep enough language for clarity
Omission should leave a recoverable meaning. Contrasting time phrases can remain, and a longer reply may be better when several actions compete. Check negatives and auxiliaries before shortening.
I have not sent the final copy, but Lina has.
I could review the draft today, although I would rather do so tomorrow.
Guided practice
Say or write your answer first. Compare the meaning and form; the model is one possible answer.
1. Shorten: Maya has finished the report, and Noor has finished the report too.
Compare a model and explanation
Maya has finished the report, and Noor has too.
The second has supports ellipsis of the shared perfect verb phrase.
2. Complete a past-action reply: Did they update the title? Yes, they ___.
Compare a model and explanation
did
The auxiliary did matches the past question.
3. Use do so: We invited them to respond, and they responded immediately.
Compare a model and explanation
We invited them to respond, and they did so immediately.
Did so substitutes for the action respond.
4. Preserve a negative contrast: I can join in the morning. I cannot join in the afternoon.
Compare a model and explanation
I can join in the morning, but I can’t in the afternoon.
The retained modal carries the negative contrast.
5. Explain what is omitted in Lina has checked it, but Maya hasn’t.
Compare a model and explanation
Checked it is omitted after hasn’t.
The negative present-perfect auxiliary is retained.
6. Use the handover note to write a compact but clear comparison of checking and sending.
Compare a model and explanation
Maya has checked the figures, and Noor has too. Noor has sent the summary, but Maya hasn’t.
Each omitted phrase has one clear nearby antecedent.
7. Explain why We suggested that she own a quieter printer, and she did so is an awkward model for simple action substitution.
Compare a model and explanation
Own describes a state rather than the kind of deliberate action naturally replaced by did so here; a fuller expression such as bought one would change the meaning and needs evidence.
Do so is not a mechanical substitute for every verb, and paraphrases must not invent an action.
8. Clarify He edited the file after he uploaded it, and she did too if you intend only that she uploaded it.
Compare a model and explanation
He edited the file after uploading it. She uploaded it too.
Restating the intended action removes competing scope or antecedent possibilities.
A short conversation
Listen first if you can, then open the transcript when useful.
Open the conversation transcript
A: Have you checked the totals and sent the summary?
B: I’ve checked the totals, but I haven’t sent the summary. Has Noor?
A: She has. She also offered to update the title, and she did so this morning.
B: Then I won’t send a duplicate. I can review her message later, but I can’t right now.

Use it in your own words
Speaking task 1
Use the handover note to compare the two colleagues’ progress without repeatedly stating full verb phrases.
Reveal a possible response
Maya has checked the figures, and Noor has too. Noor has sent the summary, but Maya hasn’t. Both can review it tomorrow, although only Maya can do so in the morning.
Success check: Preserve each person’s action and availability; keep antecedents clear.
Speaking task 2
Give a two-turn exchange in which a short reply would be ambiguous, then repair the reply.
Reveal a possible response
Have you edited the title and uploaded the document? I’ve edited the title, but I haven’t uploaded it. A bare I have would not make the two statuses clear.
Success check: Make the repair identify the intended action rather than merely adding words.
Speaking task 3
Explain the difference between useful ellipsis and careless omission using one modal and one perfect example.
Reveal a possible response
I can on Friday is clear after a question about attending. Noor has is clear after a question about sending the file. Without that context, either reply may be incomplete or confusing.
Success check: Name the recovered phrase and preserve the auxiliary’s meaning.
Take it with you
I can omit recoverable verb phrases and use substitution while preserving tense, reference and the intended action.
