The present perfect

Let's remember the use of the present perfect ...

The most common use is expressed in these examples:

I have lived in Lima for ten years.                                  

I have worked at ICPNA since 2000.

The present perfect tells you that an action began in the past and continues up to
The present.To clarify this idea, we use it with for + a period of time ( ten years) or
since + a point in time ( 2000)

Here is a link to a video and exercises with the present perfect :

Now let`s remember other uses of the present perfect:

Sheila has read " One hundred years of solitude" by Gabriel Garcìa Màrquez.


My father has traveled abroad.

In both cases the present perfect expresses that the action is completed or finished but the time is not specified.When we want to specify the time, we use the simple past:   Sheila read the book last week.




Finally,  we use the present perfect when we talk about the number of things we have done, used, consumed,etc:




I have read five novels in my life.


Terry has drunk three cups of coffee this morning.


My brother has already lost two cellphones this year.


Or when we talk about the number of times we have done something:




My father has traveled abroad five times in his life.


I have already passed three courses  at the university.
