Point B of 3

The form: have/has + past participle

has washed / have gone and so on is the present perfect: have or has, followed by a past participle.

positive and negative question
I / we / you / they have ('ve) / have not (haven't) finished have I / we / you / they finished?
he / she / it has ('s) / has not (hasn't) finished has he / she / it finished?

Regular verbs add -ed for the past participle, exactly as for the past simple: wash, I have washed; open, she has opened; stop, it has stopped.

Irregular verbs vary. Some have a past participle that matches the past simple; others do not (unit 24 has the full list).

infinitive past simple past participle
the same buy bought bought
the same make made made
different break broke broken
different eat ate eaten
different see saw seen
different go went gone
  • I've opened the window.
  • She hasn't made the beds.
  • Have they eaten?
  • Has it broken?
