What's the difference? Present Perfect and Past Simple
|Present Perfect Simple||Past Simple|
|Unfinished actions that started in the past and continue to the present:
|A finished action in someone's life (when the person is still alive: life experience):
||A finished action in someone's life (when the person is dead):
|A finished action with a result in the present:
||A finished action with no result in the present:
|With an unfinished time word (this week, this month, today):
||With a finished time word (last week, last month, yesterday):
- We use the past simple for past events or actions which have no connection to the present.
- We use the present perfect for actions which started in the past and are still happening now OR for finished actions which have a connection to the present.
- We CAN'T use the present perfect with a finished time word:
- NOT: I've been to the museum yesterday.
