Use

We use yes/no questions to ask for information and check for understanding. We generally answer ‘yes’ or ‘no’.

Example:

Is Matt a student?

Explanation:

The verb is is placed before the subject, Matt, to form a question. The person wants to know if Matt is a student.

How to build

To form a yes/no question with the present tense of the verb 'to be', we use this structure:

present tense of the verb ‘to be’ + subject (I/you/he/she/it/they/we):

• Am I your brother? Yes, you are. / No, you aren’t.

• Are you my brother? Yes, you are. / No, you aren’t.

• Is she/he/it happy? Yes, she is. / No, she isn’t.

• Are we your parnets? Yes, we are. / No, we aren’t.

• Are the happy? Yes, the are. / No, they aren’t.
