PRESENT PERFECT

The present perfect is more or less equivalent to the perfect preterite of Spanish. We will see the differences in the section on uses. In general, it is a mixture between the present and the past. We use it for actions in the past that are important in the present.


Grammatical Rules


Form 

To form the present perfect, the auxiliary verb "to have" is used in the present and the past participle of the verb. For regular verbs, the past participle is the simple form of the past. See the simple past lesson for more information on how to shape the past.

Uses (Uses)
The perfect present is used for actions that occurred in a non-concrete time before now. The specific time is not important. Therefore, we do not usually use specific time expressions ("this morning", "yesterday", "last year" ...) with the present perfect. You can use the present perfect with non-concrete time expressions ("never", "ever", "many times", "for", "since", "already", "yet" ...). This concept of non-specific time is quite difficult to understand, for this reason, below you have the particular uses of the present perfect.

1. The present perfect is used to describe an experience. We do not use it for specific actions.
Examples: 

  •  I have never flown in a plane
  •  I have worked in many different museums. 
  •  We have been to Rio de Janeiro. 

2. The present perfect is used for a change in time.

Examples:

  •  I have become more shy in my old age. 
  •  Their English has improved to lot this year. 
  •  I have learned to be more patient.


3. It is used for successes or achievements.

Examples:
  •  
  •  Our football team has won the championship three times. 
  •  Dan has finished writing his first novel. 
  •  Scientists have succeeded in curing many illnesses. 


4. We use the present perfect for actions that have not yet happened. The use of the present perfect in these cases indicates that we are still waiting for the action, therefore, we frequently use the adverbs "yet" and "still".

Examples:

  •  The plane has not arrived yet. 
  •  Our team has not won a championship yet 
  •  You have not finished your homework yet? 


5. The present perfect is used to talk about actions at different times in the past. The use of the present perfect in these cases indicates that more actions are possible in the future.

Examples:

  •  We have spoken several times, but we still can not reach an agreement.
  •  Our team has played 4 games so far this year. 
  •  I love New York! I have been there 5 times already and I can not wait to go back. 


6.In general, we use the present continuous perfect for situations that have started in the past but continue in the present. But as we have seen, there are some verbs that we can not use in continuous times. In these cases, we use the present perfect.

Examples:

  •   How long has Michael been in Barcelona? 
  •   I have loved you since the day I met you.
