The helper carries the tense
In questions with do, does or did, the helper shows present or past time. The main verb therefore stays in its base form.

What to use—and when.
Scan the middle column for your situation, then borrow the example shape. You do not need to learn the whole page at once.

Be questions
Put be before the subject
Are you ready? / Where was it?Present questions
Use do/does + subject + base verb
Where do you work?Past questions
Use did + subject + base verb
What did you choose?Modal questions
Put can, would, should or will before the subject
Would you try it again?Subject questions
Who/what is the subject, so no helper is needed
Who called you?MiniJai’s memory shortcutWith be or a modal, move that verb before the subject. Otherwise, use do, does or did plus the base verb.
Understand the choice
The details that make it click.
These are the distinctions B1+ learners need when the basic rule is not quite enough.
Be changes the pattern
When be is the main verb, move it before the subject: She is ready becomes Is she ready? No form of do is needed.
Open questions create conversation
Questions beginning with what, how and why invite detail. Closed questions are still useful for checking facts, but often need a follow-up.
Follow the answer, not your list
A natural follow-up repeats or explores something the speaker has just mentioned. This makes the exchange feel responsive rather than interrogative.
Natural examples
See it working in real English.
Read the sentence first, then use the note to notice why that form was chosen.
How long have you worked there?
Present perfect asks about a period continuing to now.
What were you doing when they called?
Past continuous asks about an action in progress.
Who gave you that advice?
Who is the subject, so no extra helper is needed.
You mentioned a new project—what does it involve?
A follow-up built directly from the previous answer.
Three common wobbles
Nearly right. One useful fix.
These are normal learner patterns. Compare the two versions and notice the smallest change that makes the sentence work.
Not thisWhere you live?
Use thisWhere do you live?
Most present-simple questions need do or does.Not thisWhat did you bought?
Use thisWhat did you buy?
Did carries the past; the main verb returns to its base form.Not thisDo you can help?
Use thisCan you help?
A modal verb becomes the helper, so do is unnecessary.Guided understanding check
Decide. Explain. Improve.
Use the full guide—not a guess. Your goal is to identify what the sentence is trying to communicate and explain why the grammar fits.
Decide
Does the sentence work? If it does, identify the form or pattern. If it does not, find the exact problem.
Explain
Connect your decision to meaning: time, specificity, word order, relationship, place or question structure.
Improve
Correct the sentence when needed, then create one new sentence about your own life using the same pattern.
01Sentence to investigateWhere you went last weekend?Check my reasoning
Needs a helper
Why: Use: Where did you go last weekend?
Your final step: Say one new, personal example that follows the same rule.
02Sentence to investigateWhat was it like?Check my reasoning
Natural open question
Why: It invites a description rather than a one-word answer.
Your final step: Say one new, personal example that follows the same rule.
03Sentence to investigateDid you like it?Check my reasoning
Useful, but closed
Why: Follow it with ‘What did you like about it?’ to keep the conversation moving.
Your final step: Say one new, personal example that follows the same rule.
Useful language
Keep these beside you.
Borrow a starting point, finish it with your own idea and say the complete sentence aloud.
What was… like?
How did… go?
What made you…?
What happened next?
How did you feel?
What surprised you?
What about you?
Have you ever…?
Would you…?
MiniJai’s speaking challenge
Build a three-question conversation path
Take the pattern out of the guide and put it into your own voice.
- Open with a question that needs more than yes or no.
- Use one detail from the answer to create a follow-up.
- Return the topic naturally or share your own answer.
