"Yes/ No" Questions

1. 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?
