What can you remember about the verb 'to do' in the present tense? Here's a review exercise to test your knowledge. Take your time and read each sentence carefully. This little word is all over the English language, so it's important to get it right!
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.
