The Present Perfect Simple
Present Perfect Simple is quite easy to understand: an action that happened in the past with no time.
There are three main uses:
Let us compare the Present Perfect Simple and the Past Simple
I went to America in the year 2000.
The speaker can clearly see in their mind when this event happened.
The action (going to America) is finished and the time is finished (the year 2000).
Present Perfect Simple = Have/Has + Past Participle
I have been to America
When did I go? That’s right, you don’t know.! You just know I went. Not only that, but I am still alive so my time is unfinished.
This is the basic idea of the Present Perfect Simple. Just remember:
THE PRESENT PERFECT SIMPLE HATES EXACT TIME!!!
