Present simple	Present continuous
Para…	rutinas, hechos, gustos	lo que pasa ahora; situaciones temporales
Forma	I swim / she swims	I'm / she's / they're swimming
Pregunta	Do you swim? Does she swim?	Are you swimming?
Negativa	I don't swim / she doesn't swim	I'm not swimming
Pistas	every day, usually, always, never, on Mondays	now, right now, at the moment, today, this week

Los verbos de estado (like, love, want, know, need) se quedan en present simple aunque hables de ahora mismo: I want an ice cream, no ~~I'm wanting~~.
