The form of the verb is usually the same as the base form, but the third person singular adds -s. Some verbs change, like 'to be', which uses 'am', 'are' and 'is', and 'to have', where the third person is 'has'. The auxiliary verb 'to do' is used in a negative structure or a question:
Do you like tea?
Does she live nearby?
I don't like them.
She doesn't go to the theatre very often.
The third person returns to the base form when 'does' or 'doesn't' are used.
