A . The
simple past
We normally
use the simple past to talk about actions that took place at a time that is
separated from the present. It is used with expressions like yesterday, on Monday, last week, in 1989,
at 6.30, How long ago ...?, etc.:
Yesterday GKN launched a takeover bid for Westland. He did his MBA at Cranfield in 1991.
We
can use the simple past and for to
talk about something that happened during a period that has now finished:
I lived
in Singapore for three years;
then I came back to England.
B. The present
perfect
The
present perfect is used to talk about the present result of past actions and
recent events, and is often used with words like ever, never, just, already, yet, and phrases of unfinished time
such as so far:
British Telecom has cut the price of peak rate phone calls by 20%.
Have you ever tried Swiss wine?
We have spoken to each other on the
phone, but we have never met. Don't
worry about the order from Siemens. I have
already dealt with it. I'm afraid I haven't
done that sales forecast yet.
I'll do it tomorrow.
The film was
released two weeks ago and so far it
has taken $45m.
C. Present
perfect simple + for and since
The
present perfect can be used with for and
since and stative verbs, or to refer
to actions that are seen as long term or permanent. We use for to talk about the duration of a period of time and since to talk about the starting point
of an action or state:
I have been with the company since
1986. I have lived here for 20 years.
It
is also used in the negative with for and
since to talk about the last time
something took place:
I haven't seen her since Monday.
I haven't seen her for three days.
It is used with since
to talk about completed actions:
Our market share has
increased by 11% since we started
advertising on TV.
D. Present
perfect continuous
The
present perfect continuous can be used with for and since to talk
about actions or activities that have gone on repeatedly or continuously for a
period of time, and are still going on:
We've been producing over 1,000 units a
week since the new factory opened.
