HELLO DEAR STUDENTS !!!!
Please try to understand the difference between Present and Past Perfect, and try to do some exercises that will give you with links.
See you and good luck.
PRESENT PERFECT
El tiempo Present Perfect se usa para hablar de acciones comenzadas en el pasado y que aún continúan en el presente. Por ejemplo:
I have been here since Monday. He estado aquí desde el lunes.
Para formarlo, se usa el auxiliar HAVE, conjugado para la persona correspondiente (cambia solamente para la tercera persona del singular), seguido del participio pasado, que es igual para todas las personas.
Observe a continuación la conjugación del verbo SER.
| TO BE |
| I |
have been |
| You |
have been |
| He |
has been |
| She |
has been |
| It |
has been |
| We |
have been |
| You |
have been |
| They |
have been |
Para los verbos regulares, el participio pasado se forma tomando el propio verbo y agregando “ed“, o “d” si termina en vocal. Si termina en “y”, se cambia por “ied“.
We have played tennis for two hours. Hemos jugado tenis por dos horas.
She has arrived late again. Ha llegado tarde de nuevo.
You have studied a lot. Yo he estudiado mucho

Past perfect, function The past perfect refers to a time earlier than before now. It is used to make it clear that one event happened before another in the past. It does not matter which event is mentioned first – the tense makes it clear which one happened first.
In these examples, Event A is the first or earliest event, Event B is the second or latest event:
| |
John had gone out |
when I arrived in the office. |
| Event A |
Event B |
| |
I had saved my document |
before the computer crashed. |
| Event A |
Event B |
| |
When they arrived |
we had already started cooking |
| Event B |
Event A |
| |
He was very tired |
because he hadn’t slept well. |
| Event B |
Event A |
Past perfect + just ‘Just’ is used with the past perfect to refer to an event that was only a short time earlier than before now, e.g.
- The trainhad just leftwhen I arrived at the station. b. She had just left the room when the police arrived. c. I had just put the washing out when it started to rain.
