The present perfect tense is used when one intends to indicate:

  • an action that occurred at a time which is indefinite and has its effect on the subject
  • or an action that occurred many times and has the possibility to occur in the present/future
  • or an action that began in the past and still going on in the present.
simple perfect tenses

When using the simple present perfect, we use the auxiliary verb have/has and the past form of the main verb (with – ed) or use an irregular verb form.

An action that occurred at a time which is indefinite and has its effect on the subject:

  • My sister has read the book through. (No time is indicated)

An action that occurred many times and has the possibility to occur in the present/future.

  • I have read Harry Potter many times. (Not habitual but occurred many times in the past)

An action that began in the past and still going on in the present.

  • He has lived in Indonesia for 15 years. (Still going on)
