Present perfect tense

The present perfect is generally the first perfect tense that students learn after the simple tenses and the present and past continuous.  This tense can be confusing at first, but here is an explanation that you may understand better.

First, the formation of the present perfect is with the auxiliary verb have followed by the past participle of the main verb.  The auxiliary have is often contracted to ‘ve and has to ‘sPast participles usually end in –ed, but the irregular ones have to be memorized.  This takes time, but you will learn them all eventually.  Study the irregular ones well because they are the most often used.

Examples:
I have known her for a long time.  (I’ve known her for a long time.)
We have visited them several times.  (We’ve visited them several times.)
She has been a wonderful house guest.  (She’s been a wonderful house guest.)

To form the negative, put not (n’t) after the auxiliary verb (have or has).

Examples:
They haven’t seen each other for weeks.
She hasn’t come back from the store yet.

To form a question, put the auxiliary verb (have or has) before the subject.

Examples:
Have you finished washing the car?
Has she found a new apartment?

Now that you know how to form the present perfect, let’s look at how to use it.  There are 3 uses.

The first use:

The present perfect is used for a one-time action in the past but with no time stated for that action.  In other words, if you don’t know when the action happened, then use the present perfect.  However, if you do know the time of the action, use the simple past.

Examples:
I’ve seen that movie.  (no time stated)
I saw that movie last weekend.  (last weekend is the time)

They have gone home.  (no time stated)
They went home an hour ago.  (an hour ago is the time)

He’s fallen off his bicycle.  (no time stated)
He fell off his bicycle on his way home.  (on his way home is the time)

Have you forgotten your keys?  (no time stated)
Did you forget your keys this morning?  (this morning is the time)

However, if the time stated is still ongoing (still happening) then use the present perfect.

Examples:
I’ve had three cups of coffee this morning.  (It’s still this morning)
I had three cups of coffee this morning.  (It’s not this morning any longer)
This year our team has won every game.  (It’s still this year)
Last year our team won every game.  (It’s not last year any longer)
He’s been sick this week.  (It’s still this week)
He was sick last week.  (It’s not last week any longer)

This use of the present perfect often has the words before and lately, which are used for one-time past actions with no time.

Examples:
Haven’t you heard that joke before?
She’s been absent a lot lately.

The present perfect can also be used with the words already, always, just, recently and yet, but these words can also take the simple past informally.

Examples:
She’s already gotten the letter.  (formal)
She already got the letter.  (informal)

Have you always done the right thing?  (formal)
Did you always do the right thing?  (informal)

They haven’t eaten yet.  (formal)
They didn’t eat yet.  (informal)

The second use:

The present perfect is used for past actions that happened more than once and may happen again.  Often, but not always, the number of times is stated, such as two, three, or four.  There can also be words that are used like numbers, such as:  a couple (2), a lot (20), a few (3), always, ever, many (20), never (0), no (0), often, and several (6).  Most of the time, you will use the present perfect with these words.  However, if the actions are finished and not still ongoing, use the simple past.

Examples:
I’ve eaten at that restaurant three times.  (and I may eat there again (ongoing))
I ate at that restaurant three times last month. (finished and not ongoing)

I’ve seen that movie a couple of times.  (and I may see it again (ongoing))

The third use:

The present perfect is used for an action that started in the past and continues to the present.  In other words, the action is still ongoing.  These words are often used with this use of the present perfect: for, since, so far, to date, and up to now.

Examples:
They have lived in that house for twenty years.  (and they still live there (ongoing))
She’s taken piano lessons since she was five years old.  (and she still does (ongoing))

Watch out for the word for, and use the simple past if the action is finished.

Examples:
