Present Perfect

  • We use the Present Perfect to talk about an action that happened in the past and has a result in the present: I´ve forgotten his name. (I can´t remember it now.) She hasn´t washed the car. (It isn´t clean now.)
  • We often use already, yet and just.
  • Already means "before now": I´ve already told her.
  • Yet means "up to now". We use it in negative sentences and questions: I haven´t asked Sam yet. Have you asked Sam yet?
  • Just means "a very short time ago": I´ve just spoken to her.
  • Already and just come after have/has. Yet comes at the end of the sentence or question.
  • We can use the present perfect to talk about experiences in our lives up to now: I´ve never been to India. I´ve worked in a hotel.
  • We often use never and ever when we talk about experiences in our lives. We use never in statements and ever in questions: I´ve never been to India. Have you ever been to India?
  • We can use the present perfect to talk about something that started in the past and continuous in the present: I´ve known Jack for six months. (I met him six months ago and I know him now.)
  • We often use for and since: we use for to say how long something has continued: I´ve been here for a week.; we use since to say when something began: He´s been a student here since September. (He became a student in September and he is a student now.)
