We make questions by putting the subject between the auxiliary verb and the main verb:
- Have you finished?
NOTE: (auxiliary verb) + subject + verb
If there is no auxiliary verb in the affirmative (ie present simple and past simple) add do/does/did.
- Do you drive?
We put the subject after the verb in questions with be.
- Are you sure?
If the question word (who, what or which) is the subject of the verb, we put the verb after the subject, as in a normal statement. We do not do/does/did with the present simple or past simple:
- Who gave yo that?
- What happened to you?
