- Here are some "yes/ no" questions:
Are you hungry?
Shall I answer the phone?
Did you enjoy the film?
We call them "yes/no" questions because the answer either "yes" or" no":
Are you hungry? Yes, I am
No, I'm not.
2. We form 'yes/ no' questions like this:
---> We put the verb be before the subject:
be + Subject
Are they busy?
Is he ready?
Was she here?
Or, we put an auxiliary verb (be, have, will, shall, can, may, etc.) before the subject:
Auxiliary + Subject + Verb
Is Mark leaving?
Have they gone?
Will they win?
Can you sing?
---> With the Present Simple verbs, we put do or does before the subject:
Do + subject + verb
Does she work in Paris?
Do they live in New York?
Do you play tennis?
Does he like ice- cream?
Note that we say:
Does she play tennis?
not (Does she plays tenis)
--->With Past Simple verbs, we put did before the subject:
Did + subject + verb
Did she visit Paris?
Did he go to Spain?
3. Here are all the forms of do questions:
Present Simple
Do I/ you/ we/ they ---> work?
Does He/ she/ it ------> work?
Past Simple
Did I/ you/ he/ she/ it/ we/ you/ they ---> work?
