    Hi!!! Sorry for being late!!

    Those are the differences between PRESENT SIMPLE and PRESENT CONTINUOUS

    PRESENT SIMPLE: 

    1. Affirmative Sentences: Sujeto + verbo principal.


    • talk. (Yo hablo.)
    • He eats. (Él come.)
    • They learn(Ellos aprenden.)

    2. Negative Sentences: Sujeto + verbo auxiliar ("to do") + auxiliar negativo ("not") + verbo principal.

    Nota: En frases negativas, el verbo auxiliar ("to do") cambia y el verbo principal es en el infinitivo.

    • do not [don't] talk. (Yo no hablo.)
    • He does not [doesn't] eat. (Él no come.)
    • They do not [don't] learn. (Ellos no aprenden.)
    3. Interrogative Sentences: Verbo auxiliar ("to do") + sujeto + verbo principal?

    Nota: Como en frases negativas, en frases interrogativas el verbo auxiliar ("to do") cambia y el verbo principal es en el infinitivo.

    • Do you talk? (¿Hablas tú?)
    • Does he eat? (¿Come él?)
    • Do they learn? (¿Aprenden ellos?)
    USES: 

    El presente simple se utiliza para hablar de cosas que suceden habitualmente.A diferencia a español, no se usa el presente simple para hablar sobre algo que está pasando en el momento en el que hablamos.
    Se suele utilizar el presente simple con adverbios de tiempo:
    always (siempre),  every day (cada día) usually (normalmente) often(a menudo) sometimes (a veces) rarely (raramente) hardly ever (casi nunca) never (nunca)...
    Excepción:
    Los adverbios de tiempo van delante del verbo, excepto el verbo "to be" (ser/estar). Cuando se usa "to be" el verbo va delante del adverbio.
    • Ejemplos:
    • am always happy. (Siempre estoy contento.)
    • He is often sick. (A menudo él está enfermo.)
    • They are rarely late. (En raras ocasiones llegan tarde.)



    PRESENT CONTINUOUS

    1. Affirmative Sentences: Sujeto + verbo auxiliar ("to be") + gerundio ("-ing").

    • I'm talking(Estoy hablando.)
    • He's eating(Está comiendo.)
    • They're learning(Están aprendiendo.)
    2. Negative Sentences: Sujeto + verbo auxiliar ("to be") + auxiliar negativo ("not") + gerundio ("-ing").

    • I'm not talking(No estoy hablando.)
    • He's not [He isn't] eating(No está comiendo.)
    • They're not [They aren't] learning(No están aprendiendo.)
    3. Interrogative Sentences: Verbo auxiliar ("to be") + sujeto + gerundio ("-ing")?

     
    • Are you talking(¿Estás hablando?)
    • Is he eating(¿Está comiendo?)
    • Are they learning(¿Están aprendiendo?)
    USES: 

    1. El presente continuo se utiliza para hablar sobre algo que está pasando en el momento en el que hablamos. Expresiones de tiempo tales como "now", "right now" and "at the moment" indican el presente continuo.

    2. También lo usamos para hablar de algo que está sucediendo en la actualidad pero no necesariamente cuando hablamos. En este caso, se utiliza expresiones de tiempo como "currently", "lately" or "these days".

    3. Usamos el presente continuo para hablar de algo que está ya decidido que se hará en el futuro próximo.El uso del presente continuo indica que sea bastante seguro que el acontecimeinto futuro pasará.
