One of the uses of the present perfect s to talk about experiences in the past, when we don’t mention the exact time.
In affirmative sentences the order is subject + have / has + past participle.
I’ve tried rock climbing.
He’s ran a marathon.
In negative sentences the order is subject + have / has + not + past participle, haven’t tried roller skating.
He hasn’t played in the school team.
The past participle of regular verbs is the same as the past simple of regular verbs – they end in –ed.
Jump – jumped
play – played
miss – missed
The past participles of irregular verbs are all different and you have to learn them. See Irregular Verbs list, p159.
