do & simple present
El verbo do puede ser fuerte o debil. Es como si fueran gemelos: se ven igual, pero no son lo mismo:
Verbo fuerte DO no se traduce al español (no tiene traduccion), es el auxiliar que nos sirve para hacer el presente simple del ingles. Solo aparece en negativo o interrogativos. No se usa en afirmativo, a menos que queramos hacer enfasis.
I work - yo trabajo
I do not work (sin contraccion) - I don't work (con contraccion): yo no trabajo
Verbo débil DO - se traduce como 'hacer'. Cuidado ⚠️ no se confundan, este si tiene traduccion.
AFFIRMATIVE: I do (verbo débil) the homework - yo hago la tarea (aparece en afirmativo)
I do (verbo fuerte que hace la negacion) not do (verbo debil que signifca 'hacer') the homework
NEGATIVE: I do not do the homework
3a persona:
She does the homework
She does not do the homework = She doesn't do the homework
