Siempre dos piezas: am / is / are + verbo con -ing.
I working · she is work · I'm working · she is working
No usa do. Niega con not y pregunta poniendo am / is / are delante.
Do you working? · she doesn't working · Are you working? · she isn't working
Es para ahora, estos días o planes ya organizados, no para rutinas.
I'm getting up at 7 every day · I get up at 7 every day · Today I'm working from home
No son acciones, son estados: like, love, hate, want, need, know, understand, believe, remember, mean y have cuando es «tener». Van en presente simple aunque hables de ahora.
