**** Traducción al castellano del uso:
Present Simple. Lo usamos para hablar sobre acciones que hacemos normalmente, a diario.
También, para verdades generales y hechos científicos.
Otro uso, es el de expresar horarios (de trenes, aviones...).
Present Continuous. Lo usamos para hablar sobre acciones que están sucediendo en el momento en que estamos hablando.
También, para hablar de cosas que están sucediendo actualmente, no necesariamente en el momento de hablar.
