Present simple	Present continuous
Para…	rotinas, fatos, gostos	o que está acontecendo agora; situações temporárias
Forma	I swim / she swims	I'm / she's / they're swimming
Pergunta	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

Os verbos de estado (like, love, want, know, need) ficam no present simple mesmo quando você fala de agora: I want an ice cream, e não ~~I'm wanting~~.
