PRESENT PERFECT vs. SIMPLE PAST

PRESENT PERFECT vs. SIMPLE PAST

NAME ………………………………………CLASS……………………….DATE………………………..

Has the time period finished?

Rule
Example
Explanation
The present perfect is used when the time period has NOT finished.

(This week has not finished yet.)
The simple past is used when the time period HAS finished.

(Last week has finished.)

Is it new information or old?

Rule
Example
Explanation
The present perfect is often used when giving recent news.
Martin has crashed his car again.
(This is new information.)
The simple past is used when giving older information.
Martin crashed his car last year.
(This is old information.)

Is it a specific time?

Rule
Example
Explanation
The present perfect is used when the time is not specific.
I have seen that movie already.
(We don't know when.)
The simple past is used when the time is clear.

(We know exactly when.)

We use time expressions like  'ever', 'never', 'since' with the present perfect.



  • I've never seen so many people here before.
  • Have you ever been more surprised?
  • I've done a lot since we last talked about it.






We use time expressions like 'yesterday', 'ago', 'last year', 'in 1999' with the past simple.



·         We spoke to him yesterday.
·         He came in a few moments ago.
·         We made our last purchase from them over a year ago.
·         She joined the company in 1999.


We can use the time phrase 'for' with both forms, but with different meanings.
·                                 I lived in Paris before I moved here. for a couple of years
·                                 I've lived in Paris for a couple of years and Ι love it.
