Present perfect vs simple past
The simple past and the present perfect are similar because they can both be used to talk about
completed past actions.
We use the present perfect to talk about what happened, not when it happened. We use the following
time expressions ever, just, already, yet, before, many times, etc. in present perfect tense.
e.g.
This is my favourite movie. I have seen it many times. (We don’t know when the speaker saw the movie,
but we know that s/he saw it)
When we want to say when an action happened, we use the simple past and we use time expressions
such as: yesterday, ago, last week,/month/year.
e.g.
This is my favourite movie. I saw it last night. (We know when the speaker watches the movie: last night)
Note: When we talk about our experiences using ever, we continue the conversation with simple past
to receive more details.
e.g.
A: Have you ever been abroad?
B: Yes, I have.
A: Really? Where did you go?
B: I went to Germany last year.
