You use 'to be' to start a question when the verb of the declarative phrase is also 'to be'. The conjugation of the verb 'to be' should match the subject.  For example:


Are you happy at school?  (SUBJECT= you, TO BE CONJUGATION= Are)

Yes, I am happy at school.


Is she nice? (SUBJECT=she, TO BE CONJUGATION= Is)

Yes, she is nice.


Are they in the USA? (SUBJECT= they, TO BE CONJUGATION: Are)

No, they are not in the USA.  They are in England.


You should use the verb 'to do' to ask questions about actions or verbs.


Do you play guitar?

No, I do not play guitar.

Yes, I do.

Yes, I do play guitar.

Yes, I play guitar.


Does he like to play football?

Yes, he does like to play football.

Yes, he does.

Yes, he likes to play football.

No, he does not like to play football.


You should use the past simple of 'to be' and the past simple of 'to do' (did) to ask questions about things that happened before now, that happened in the past.
