Grammar (1) - Present Perfect vs. Simple Past
The Simple Past is used when two specific conditions are fulfilled:
a)
The action (or event) is finished b) You know exactly when the action (or event) took place
She phoned me one hour ago.
When did you see her? / I saw her yesterday.I met them last night.
How long ago did you write your essay? I wrote it two days ago.
When did you have your car repaired? I had it repaired last week.
When did you last go tot he cinema? I last went to the cinema last month.
When did she meet her boyfriend? She met him when she was a student.
They got married in 1995.
I didn’t see my friends last weekend when I went to the football match.
He didn’t see his parents for four years.
How long were you a student? I was a student for four years, between 1983 and 1987.
The Present Perfect is used…
a) …when at least one of the two conditions used for the Simple Past is
missing
She has been to Paris / She’s been to Paris.
I have seen
that film before. / I’ve seen that film before.
The actions are finished BUT you don‘t know when
or it‘s not important to know when. In other words,
you talk about something (action / event…) that happened before but you don’t
say or don’t know exactly when it happened.
NOTE: Adverbs of time (but indefinite) are used with the Present Perfect.
In the affirmative: just and already
In the negative: never and yet
In the interrogative: ever and yet
So, was it 5 minutes ago? Half an hour ago? One hour ago? We don’t know or don’t care.
He never saw the sea.
Also with the Simple Past but this means he
never had the possibility of seeing it for example when he still could drive or
leave his village but not anymore because he could be too old to do it now or
simply because he is dead. Note the use of YET combined with the negative form of the verb (have not – ‘ve not – haven’t / / has not – ‘s not – hasn’t )
If your answer is yes, they may ask you then when you did it!
Oh yes? And when did you go there?
In 2008. I was a student then. It was during my Erasmus programme…
Yes, I have. I went to see it when it came out…
b) …when both conditions used for the Simple Past are missing (the action is not finished and the
time of the action is not completed)
He’s lived
in this small town all his life. (→part of the past and up to the present)
NOTE: He lived in this small town all his life.
It means he is now dead and he is now living somewhere else.
(She arrived in London two weeks ago and she’s still there now)
I have known them for 10 years.
(I met her 10 years ago and I still know her today.)
She’s owned her car for a very long time.
(She bought it a long time ago and still has it now.)
She has been
working since 4 o‘clock.
(She started
working at 4 o’clock and hasn’t stopped since.)
They’ve been
unlucky since they decided to settle
down there.
(They started
being unlucky at the time they settled down there and now their situation
hasn’t changed.)
NOTE:
She was in London for two weeks.
(She’s elsewhere now or she’s back home)
I knew her for 10 years.
(But I lost
touch with her because she moved away or she didn’t want to see me again or
simply because she died.)
She owned her
car for a very long time.
(and now she
owns a new one.)
SINCE or FOR?
SINCE of
FOR are both used with perfect tenses.
FOR is
used with reference to a period of time and SINCE with reference to the start
of a period of time.
