Before you start
How could you respond politely when someone assumes you did not enjoy something?
Useful background: Do/does/did; base verbs; common auxiliaries.
Add do, does or did before a base verb
In an affirmative sentence without another auxiliary, do can add emphasis. Match the tense and subject, then use the base verb. The emphasis is often heard as stress on the auxiliary.
I do understand your point.
She does work hard.

Correct or partly agree
Emphatic do can reject a mistaken negative assumption or concede a point before adding a contrast. It does not automatically signal anger. Make the following qualification clear.
I did enjoy the talk, but it was too long.
We do need more time, although the plan is almost ready.
Stress an auxiliary already present
When a sentence already contains be, a modal or a perfect auxiliary, stress that auxiliary rather than adding do in the ordinary statement pattern. The exact delivery must support the intended message.
I am listening.
I can help, but not until tomorrow.

Guided practice
Say or write your answer first. Compare the meaning and form; the model is one possible answer.
1. Add emphasis: I understand the problem.
Compare a model and explanation
I do understand the problem.
Do adds emphasis before the base verb.
2. Add emphasis: She knows the answer.
Compare a model and explanation
She does know the answer.
Does carries agreement; know returns to the base form.
3. Add past emphasis: We checked the date.
Compare a model and explanation
We did check the date.
Did carries the past tense; check is the base form.
4. Correct: He does works hard.
Compare a model and explanation
He does work hard.
Do not mark third-person agreement twice.
5. Correct: I do can help.
Compare a model and explanation
I can help.
Stress can rather than adding do before the modal.
6. Give a qualified positive reaction to a film you enjoyed but found long.
Compare a model and explanation
I did enjoy the film, but it was too long.
Preserve both the positive judgement and its limit.
7. Does emphatic do always mean the speaker is angry? Explain.
Compare a model and explanation
No. It can reassure, politely correct or acknowledge a point, depending on context and delivery.
Emphasis and anger are not the same meaning.
8. Someone thinks you have not read a message. Respond with emphasis on the existing auxiliary.
Compare a model and explanation
I have read it. I haven’t had time to reply yet.
Have is already present in the perfect construction.
A short conversation
Listen first if you can, then open the transcript when useful.
Open the conversation transcript
A: I thought you didn’t like the new lesson format.
B: I do like it. I just think the instructions could be shorter.
A: So you don’t want to return to the old version?
B: No. I did prefer one activity in the old version, but the new structure is much clearer overall.

Speaking task 1
Respond to three mistaken assumptions: you did not read a file, you cannot help and you dislike a plan. Add one limit to each response.
Reveal a possible response
I did read the file, but not the appendix. I can help after lunch. I do like the plan, although the final step needs a clearer deadline.
Success check: Correct the assumption without deleting the qualification or adding unnecessary hostility.
Speaking task 2
Give balanced feedback on a fictional lesson or presentation using two emphatic positives.
Reveal a possible response
I did enjoy the examples, and I do think the main idea is useful. I would shorten the opening, however, so there is more time for practice.
Success check: Make the positives genuine and the contrast specific.
Speaking task 3
Say the same emphatic sentence in a reassuring and a frustrated context. Explain what changes beyond the grammar.
Reveal a possible response
I do understand can reassure someone who worries they were unclear, or correct someone who keeps repeating themselves. The surrounding words, pace and tone shape how it is received.
Success check: Distinguish grammatical emphasis from a fixed emotional label.
Take it with you
I can use emphatic auxiliaries to correct an assumption, reassure someone or express qualified agreement.
