Present Perfect

Present Perfect Tense

The present perfect is used to describe an action that began in the past and continues to exist in the present.

Use. Both the present perfect and simple past both describe events that began in the past and were completed in the past.


  1. Only the past simple can be used with a time element (“seven o’clock” or a time word such as yesterday).  I studied for my exam yesterday/last week/at seven o’clock.
  2. The present perfect is used when the event has a direct relationship to the present. (uses words such as already, just, or yet). I have already studied for my exam so I can come to your party. 
  3. In the Past Simple, negative statements “only” negate the positive. In the Present Perfect, negative statements both negate the positive AND show the intention to complete the action sometime in the future.
