Review of auxiliaries Do/Does
Do and does are similar to modal verbs. They are used to make questions and statements when there is no other auxilary. "Do you want some?"
Use does if the subject is third-person singular (he, she, it, Mike, Amanda, the car). Use do everywhere else i.e. plural nouns and with the pronouns I, we,
you and they. Did is used for past tense.
Doesn't is the contracted (short) form of does not. Don't is the contracted form of do not.
