How to use the present perfect tenses
in English
When do you use the
Past Simple ("I did") and the
Present Perfect ("I have done")?
The tense you choose depends on how you consider the event. Is it
finished, or is there still a connection to the present?
If you use the Past Simple ("I
did"), you consider the event or events as finished and in the past.
This tense is often used with a time reference: last year, last week, in
1991, this morning (if it's now the afternoon) and so on.
With the Present Perfect ("I have
done"), there is a connection to the present.
For example, "I have lived here
for five years." (I still live here.)
Uses of the Present
Perfect
When the past affects the present
"I've lost my wallet."
This means that you have lost your wallet (sometime in the past, but we
don't know when), but what is really important is that you don't have it
now, at the time of speaking.
If instead, you say "I lost my
wallet", people understand that you lost it, but not that it affects the
present. They expect you to tell them about the time that you lost the
wallet.
We use the Present Perfect tense to show that something has a result or
a connection to now. This means that it's used to give news.
"The Euro slips!"
(headline)
"The Euro has slipped against the
pound again."
(news report)
"My sister has had a baby."
(announcing news)
Experiences
Your experiences make you the person you are now. We don't use dates and
times to give information on what makes you this person.
"I've been to New Zealand." (I
know something about New Zealand.)
We often ask questions about people's experiences with
ever. For example, "Have
you ever been white-water rafting?"
States or activities that started in the
past, which have continued up to now and will probably continue
into the future.
"I have worked here
for five years."
"I have lived here
since 1994."
Use since to give the date that
an activity or state started and use for
to give the period of time the activity or state has lasted.
Recent past
"Have you finished yet?"
"I've already written the
report." (Here it is.)
In these type of examples, we often use
yet, already still, just and
recently.
Note: American English uses the Past Simple instead of the Present
Perfect in these examples. For instance, "Did
you eat yet?"
Using both tenses in
a conversation
"Have you travelled much?"
"Yes, I've been to the USA."
"Oh really? When did you go?"
The first question and the reply concern a person's experience, so they
use the Present Perfect. But the second question asks for more
information about the experience. Because it refers to a past time (when
the person went to the USA), the Past Simple is used.
The conversation could continue:
"Oh really? When did you go?"
"Two years ago. I visited a
friend in California, but I only stayed a week."
"Did you like it?"
"Yes, it was a fantastic trip."
How to use the Present Perfect Continuous.
Temporary situations
Like the Present Continuous and
Past Continuous, the
Present Perfect Continuous is
used to talk about activities or states that are temporary, rather than
permanent.
Compare:
"I have been the Marketing
Manager for five years." (This is
my job.)
"I've been working on a new
customer database." (This is a temporary project.)
Unfinished situations
"I've been writing letters all
morning." (I still haven't finished them.)
"This morning I've written three
letters." (They are all finished.)
Repeated and continuous actions
"No wonder you're not hungry. You've
been eating sweets for the last hour." (One sweet after another.)
