🕰️ PART 1: Understanding “Do” (Present Tense)
What does “do” mean?
“Do” is a verb that can be used in different ways. In this lesson, we focus on “do” as a helping verb (auxiliary verb) in the present tense.
When do we use “do”?
We use “do” when we are:
- Asking about something happening now or regularly (present tense)
- Making negative statements in the present
- Asking general questions
Pronouns and “do”
| Subject | Verb Form |
|---|---|
| I | do |
| You | do |
| We | do |
| They | do |
| He/She/It | does |
“Does” is the third person singular form of “do” used with he, she, or it.
Examples:
- I do my homework every day.
- You do your job well.
- He does his homework after school.
- She does the dishes at night.
- They do yoga every morning.
Questions with “do”
Structure: Do/Does + subject + base verb

- Does she play the guitar?
Negative sentences with “do”
Structure: Subject + do/does + not + base verb
- I do not (don’t) like cold weather.
- He does not (doesn’t) play football.
- They do not go to school on Saturdays.
⏲️ PART 2: Understanding “Did” (Past Tense)
What does “did” mean?
“Did” is the past tense of “do.” We use it to talk about things that happened before now.
When do we use “did”?
We use “did” when:
- Asking questions about the past
- Making negative statements in the past
- Talking about completed actions in the past
Pronouns and “did”
Good news! “Did” is the same for all subjects.
- I did
- You did
- He/She/It did
- We did
- They did
Examples:
- I did my homework yesterday.
- You did a great job.
- She did the dishes last night.
- We did our best.
- They did not come to school.
Questions with “did”
Structure: Did + subject + base verb
- Did you see the movie?
- Did he call you?
- Did they finish their work?
Note: After “did,” the main verb stays in the base form (no -ed or past tense).
Negative sentences with “did”
Structure: Subject + did not (didn’t) + base verb
- I did not go to the party.
- She did not eat breakfast.
- They did not finish the test.
✉️ Summary Table: Do vs Did
| Tense | Helping Verb | Example Sentence | Question | Negative Sentence |
| Present | do/does | She does her homework. | Does she do her homework? | She does not do homework. |
| Past | did | She did her homework. | Did she do her homework? | She did not do homework. |
❌ Common Mistakes and How to Avoid Them
Mistake 1: Using “did” with a past verb
Incorrect: Did you went to school? Correct: Did you go to school?
Mistake 2: Using “do” for past actions
