  Present Perfect The presentperfect is a verb tense in the English language that narrates events that have already occurred at a time in the past but that continue to have relevance in the present. In this sense, it contrasts with the simple past, which is used to refer to actions that took place in the past but that no longer necessarily have any validity with the present.

  Present Perfect Tense. Functions UnfinishedActions 1: We use this tense when we want to talk about unfinished actions or states or habits that started in the past and continue to the present. Examples: I've known Karen since 1994. She's lived in London for three years. 'Since' and 'For' We use 'since' with a fixed time in the past (2004, April 23rd, last year). Examples: I've known Sam since 1992. I've liked chocolate since I was a child. We use 'for' with a period of time (2 hours, three years, six months). Examples: I've known Julie for ten years. She's had a cold for a week. Finished Actions 2: Life experience. These are actions or events that happened sometime during a person's life. We often use the words 'ever' and 'never' here. Examples: She's the loveliest girl I've ever seen. We have never seen that film. 3: With an unfinished time word (this month, this week, today). Examples: I haven't seen her this month.

  Present Perfect Tense. FunctionsPart 2 4: A finished action with a result in the present (focus on result). We often use the present perfect to talk about something that happened in the recent past ( still important now). I've lost my keys (so I can't get into my house). She's hurt her leg (so she can't play tennis today). 5: We can also use the present perfect to talk about something that happened recently, even if there isn't a clear result in the present. we often use the words 'just / yet / already / recently'. Examples: The Queen has given a speech. I've just seen Lucy. Been and Gone In this tense, we use both 'been' and 'gone' as the past participle of 'go'. We use 'been' (often when we talk about life experience). Examples: I've been to Paris (in my life, but now I'm in London, where I live). She has been to school today (but now she's back at home). We use 'gone' (often when we are talking about an action with a result in the present). Examples: Where's John? He's gone to the shops (he's at the shops now). Julie has gone to Mexico (now she's in Mexico).
