Lições de gramática

No presente simples, as perguntas e as negativas precisam do verbo auxiliar do. - do / don't com I, you, we, they e substantivos plurais: Do you live here? I don't eat meat. - does / doesn't com he, she, it e substantivos singulares: Does she speak French? He doesn't drive. As formas completas são do not e does not; na fala dizemos normalmente don't e doesn't. Depois de do ou does, o verbo principal fica na forma base, sem -s: Does she speak? (não speaks), He doesn't eat meat (não eats). Uma palavra interrogativa vem primeiro: Where does your sister work? How often do you go to the gym? Em perguntas e negativas, o verbo be não usa do: Are you ready? She isn't here.
