The Present Perfect with Repetition up to the Present • When we talk about the repetition of an action in a time period that includes the present, we can use the present perfect. The present perfect shows that the action can happen again in this time period because the time period is not finished. • Ex) I’ve written three E-mail mails today. (It is possible that I will write more mails today.) The Present Perfect: Indefinite Past Time • We use the present perfect to refer to an action that occurred at an indefinite time in the past that still has importance to the present situation. • Ex) Have you ever gone to an AA meeting? Yes, I have • (AA = Alcoholics Anonymous – they help people and families struggling with alcohol addiction)
