present perfect or past?48 present perfect or past?1not thinking about the presentWe use the present perfect if we are thinking about the past and present together. We do not use the present perfect if we are not thinking about the present. Compare:–My sister has learnt French. (She can speak French now.)Shakespeare probably learnt Italian. (not Shakespeare has probably learnt Italian.)–We've studied enough to pass the exam. (The exam is still to come.)We studied enough to pass the exam. (The exam is over.)–Anna and Daniel have got married! (news)My parents got married in Canada.We do not use the present perfect in story-telling.Once upon a time a beautiful princess fell in love with a poor farmer. (not … has fallen in love …) 
2finished-time words: present perfect not usedWe do not often use the present perfect with words that refer to a completely finished period of time, like yesterday, last week, then, when, three years ago, in 1970. This is because the present perfect focuses on the present, and words like these focus on the past, so they contradict each other. Compare:–Have you seen Lucy anywhere?I saw Lucy yesterday. (not I have seen Lucy yesterday.)–Tom has hurt his leg; he can't walk.Tom hurt his leg last week. (not Tom has hurt his leg last week.)–What have you done with the car keys? I can't find them.What did you do then? (not What have you done then?)–My brother has had an accident. He's in hospital.When did the accident happen? (not When has the accident happened?)–All my friends have moved to London.Sam moved three years ago. (not Sam has moved three years ago.)But with words that mean 'at some/any time up to now' (like ever, before, never, yet, recently, already), we normally use the present perfect (47.4).Have you ever been to Chicago?I've seen this film before.For tenses with just and just now, 503.3time not mentionedWe use the present perfect when we are thinking of a period of 'time up to now', even if we do not mention it.Have you seen 'Romeo and Juliet'? (= Have you ever seen it? or Have you seen the present production?)You've done a lot for me. (… up to now)On the other hand, we do not use the present perfect when we are thinking of a particular finished time, even if we do not mention it.Did you see 'Romeo and Juliet'? (It was on TV last night.)My grandfather did a lot for me. (… when he was alive)4news and detailsWe normally use the present perfect to announce news.Have you heard?
