El Past Continuous se refiere a lo que estaba sucediendo mientras que el Past Simple se refiere a lo que de repente pasó mientras algo ya estaba ocurriendo. En estos casos las conjunciones que usamos para unir estas acciones son when: cuando; while: mientras Example: The teacher was writing on the board when the bell rang . El profesor escribía/ estaba escribiendo en la pizarra cuando sonó el timbre. The teacher was writing on the board The bell rang

26. PAST PERFECT DE UN VERBO IRREGULAR Como hemos visto en las anteriores diapositivas el past perfect se forma con had + participio , cuya terminación es igual que la del pasado de un verbo regular, esto es, con la terminación “-ed”. De nuevo tenemos el problema de los verbos irregulares . El participio de estos verbos tiene su propia forma y por tanto habrá que aprender dicho participio. Por ejemplo: Write Witten You had written Know Known She had known

27. USE OF PAST PERFECT El past perfect se usa para describir una acción pasada que es anterior a otra pasada. Example: I had laid the table before my guests arrived Había puesto la mesa antes de que llegaran mis invitados ¿Qué acción sucede en primer lugar? Poner la mesa Por tanto el verbo va en past pefect

Ejemplo: Have you ever seen a falling star?: ¿ Has visto alguna vez una estrella fugaz? NEVER: nunca . Se coloca antes del verbo principal (del participio).

Podemos usar este adverbio en distintas posiciones dentro de la frase. Ejemplo: Have you been on a diet recently ? (final de la frase) ¿ Te has puesto a dieta recientemente?

I have eaten snails. He comido caracoles 3- Usamos el present prefect con referencias de tiempo que aún no han acabado .como por ejemplo: this year, today .. Ejemplo: I’ve seen Carla today . Hoy he visto a Carla PAST SIMPLE 1- Preguntamos cuándo hizo alguien algo . Ejemplo: When did you eat snails? ¿Cuándo comiste caracoles? 2- Decimos cuándo hicimos algo . Evidentemente acompañaremos esta frase con una referencia de tiempo pasada. Ejemplo: I ate snails when I was a child . Comí caracoles cuando era niño. 3- Usamos el past simple con referencias de tiempo ya acabadas , como por ejemplo: last year, yesterday Ejemplo; I saw Carla yesterday . Ayer vi a Carla

You have tears in your eyes! ¿Qué pasa? ¡Tienes lágrimas en los ojos! - Don’t worry. I have been peeling onions. No te preocupes. He estado pelando cebollas

49. USOS ESPECIALES DE PRESENT PERFECT (CONTINUOUS) CON FOR/SINCE. Es muy frecuente usar ambos tiempos verbales con las preposiciones de tiempo for y since . Son frases del tipo: I have been a teacher for 23 years . Soy profesor desde hace veintitrés años. I have been living in Madrid since 1975 . Vivo/Llevo viviendo en Madrid desde 1975. Llama la atención como he traducido estas frases ¿verdad?

50. USOS ESPECIALES DE PRESENT PERFECT (CONTINUOUS) CON FOR/SINCE. En primer lugar hay que saber que usamos el present perfect simple o el present perfect continuous con for/since para referirnos a acciones que empezaron en el pasado pero que todavía se continúan en el presente. I became a teacher 1987 2010 I am a teacher I have been a teacher for 23 years Soy profesor desde hace 23 años I have been a teacher since 1987 Soy profesor desde 1987

51. USOS ESPECIALES DE PRESENT PERFECT (CONTINUOUS) CON FOR/SINCE. DIFERENCIAS ENTRE FOR Y SINCE. FOR : se usa para indicar la cantidad de tiempo que llevamos haciendo algo. Ejemplo: I have been studying sign language for four months : Llevo estudiando/estudio lengua de signos desde hace cuatro meses. SINCE: se usa para indicar el momento o fecha exacta en que empezamos a hacer algo . Ejemplo: I have been studying sign language since October : Llevo estudiando/estudio lengua de signos desde octubre.

52. EXPRESIONES CON FOR/SINCE FOR Three minutes Two hours Some weeks (unas, algunas semanas) One month Many years Ages (mucho tiempo) A long time (mucho tiempo) ...... Como se ve con estos ejemplos, siempre usamos for con expresiones referidas a cantidades de tiempo . SINCE Nine o’clock Yesterday Thursday 2006 Last Christmas I was a child (era niño) I first saw you... (te vi por primera vez) ....... Como se ve a partir de estos ejemplos, usamos since con expresiones de tiempo exactas, que nos marcan el comienzo de una acción .

53. HOW LONG WITH PRESENT PERFECT (CONTINUOUS). Es muy frecuente usar el Present Perfect Simple y el Present Perfect Continuous en interrogativas con how long . En este caso lo traducimos al castellano como: ¿ Cuánto tiempo hace que Ejemplos: How long have you been a teacher? ¿Cuánto tiempo hace que eres profesor? How long have you been living in Madrid? ¿Cuánto tiempo hace que llevas viviendo en Madrid? haces algo? llevas haciendo algo?

54. EQUIVALENCIA CON LOS TIEMPOS VERBALES EN CASTELLANO Cuando usamos el Present Perfect Simple (have/has+participio) o el Present Perfect Continuous (have/has been+ing) con las preposiciones For /Since la equivalencia en castellano es: 1- Presente de indicativo 2- Llevar haciendo algo x tiempo . Ejemplos: 1- I have known my English teacher since October: Conozco a mi profesor de inglés desde octubre. 2- I have been teaching for 23 years: Llevo dando clase desde hace 23 años.

55. PRESENT PERFECT SIMPLE / PRESENT PERFECT CONTINUOUS CON FOR/SINCE. Por último saber cuándo usar Present Perfect Simple (have/has+participio) y cuándo Present Perfect Continuous (have/has been+ing). Present Perfect Simple Non-action verbs: be – have (cuando expresa posesión) – know- love-hate... Ejemplos: I’ve had this car since 1999: tengo este coche desde 1999 They have known their teacher for four months: Conocen a su profesor desde hace cuatro meses.

56. PRESENT PERFECT SIMPLE / PRESENT PERFECT CONTINUOUS CON FOR/SINCE. Present Perfect Continuous Action verbs: Verbos que describen una acción, en vez de un estado, como en la diapositiva anterior Ejemplos: I’ve been working as a teacher since 1987: Trabajo / Llevo trabajando de profesor desde 1987 They have been learning English with Jesús for four months: Llevan aprendiendo inglés con Jesús ( desde hace ) cuatro meses .
