Tema 1 — Tenses review: Present and Past
El Present Simple se usa para hábitos y verdades generales (She works every day). El Present Continuous (am/is/are + -ing) para acciones en progreso (I am studying now). El Past Simple para acciones terminadas en un momento concreto (They visited London last year). El Past Continuous (was/were + -ing) para acciones en progreso en el pasado (It was raining when I left). Clave: los state verbs (know, believe, want, belong, own) NO se usan en tiempos continuos.
Conceptos clave:

Present Continuous: acciones en curso o temporales (I am reading a book this week)
Past Simple: acciones completadas (We went to Paris in 2023)
Past Continuous: acción en progreso interrumpida (I was cooking when the phone rang)

Tema 2 — Future forms: will, going to, Present Continuous
Will se usa para predicciones generales (It will rain tomorrow), decisiones espontáneas (I’ll help you) y promesas (I will always love you). Going to para planes e intenciones decididos previamente (I’m going to study Medicine) y predicciones con evidencia (Look at those clouds — it’s going to rain). El Present Continuous como futuro para planes fijos con fecha y hora (I’m meeting John at 5 pm). Present Simple para horarios (The train leaves at 8:30).
Going to: planes previos + predicciones con evidencia visible
Present Continuous: citas y planes fijos (I’m flying to London on Friday)
Present Simple: horarios y programas (The film starts at 9 pm)
Shall: sugerencias y ofertas formales (Shall I open the window?)
Tema 3 — Perfect tenses: Present, Past, Future
Present Perfect Simple (have/has + pp): conecta pasado con presente. Con for (duración), since (punto de inicio), already, yet, just, ever, never. Ejemplo: She has lived here since 2010. Present Perfect Continuous (have been + -ing): enfatiza la duración (I have been waiting for 2 hours). Past Perfect (had + pp): acción anterior a otra pasada (When I arrived, she had already left). Future Perfect (will have + pp): acción completada antes de un momento futuro (By 2030, I will have finished university).

Past Perfect: pasado anterior a otro pasado (They had eaten before we arrived)
Future Perfect: completado antes de un momento futuro (By June, I will have graduated)
For vs Since: for + duración (for 3 years) / since + punto (since 2020)
