Form of Present Perfect Simple

  • P: He has spoken.
  • N: He has not spoken.
  • Q: Has he spoken?

Use of Present Perfect Simple

Present Perfect Simple is used for actions that started in the past and stopped recently or are still going on. The focus is on the result.
  • Action that is still going on
    Situation that is still the same as it was in the past. We want to emphasise that the situation has not changed.
    Examples:
    Your advice has always been extremely helpful.
    We have not yet received a remittance for the goods supplied to you.
  • Action that stopped recently
    Action that has just been completed. We want to emphasise the result.
    Examples:
    have typed five letters.
    have just received your mail.
  • Action in the past that has an influence on the present
    Action that was completed in the past, but has an influence on a present situation. Note that you must not give a certain time for the action in the past (if you want to use a time expression, you must use Simple Past).
    Examples:
    have lost Misses Wildes phone number.
    We have agreed on the following points:
  • Action that so far has taken place never, once or several times
    Action that happened / did not happen in the past. We want to emphasise how often the action has taken place so far.
    Examples:
    have never been to our New York subsidiary.
    Misses Newton has already phoned three times to inquire about the delivery of her goods.

The present progressive puts emphasis on the course or duration of an action.
Time line
The present progressive is used for actions going on in the moment of speaking and for actions taking place only for a short period of time. It is also used to express development and actions that are arranged for the near future.
Present progressive is also known as present continuous.
