Present perfect 1 (I have done) Watch complete video - com senha A Study this example situation: Tom is looking for his key. He can't find it. He has lost his key. He has lost his key = He lost it recently, and he still doesn't have it. The pesent perfect simple is have/has + past participle. The past participle often endes in -ed (finished /decided etc.), but many important verbs are irregular (lost / done / written etc) For a list of irregular verbs click here. B When we say that 'something has happened', this is usually new information: - Ow! I've cut my finger. - The road is closed. There's been (there has been) an accident. - (from the news) Police have arrested two men in connection with the robbery. When we use the present perfect, there is a connection with now. The action in the past has a result now: - 'Where's your key?' 'I don't know. I've lost it.' (= I don't have it now) - He told me his name, but I've forgotten it. (= I can't remember it now) - 'Is Sally here?' 'No, she's gone out.' (= she is out now) - I can't find my bag. Have you seen it? (= Do you know where it is now?) C You can use the present perfect with just, already and yet. Just = a short time ago: - 'Are you hungry?' 'No, I've just had lunch.' - Hello. Have you just arrived?' We use already to say that something happened sooner than expected: - 'Don't forget to send the letter.' I've already sent it.' - 'What time is Mark leaving?' 'He's already gone.' Yet = until now. Yet shows that the speaker is expecting something to happen. Use yet only in questions and negative sentences: - Has it stopped raining yet? - I've written the letter, but I haven't sent it yet. D Note the difference between gone (to) and been(to): - Jim is on holiday. He has gone to Italy. (= he is there now or on his way there) - Jane is back home now. She has been to Italy. (she has now come back) Exercises home |
