Present Perfect active: passive: Someone has made the arrangements for us. The arrangements have been made for us. ■ Using the Present Perfect Tense: FOR or SINCE? We use Present Perfect tense to talk about action which started in the past and continues up to the present. Examples I have had this computer for about a year. How long have you been at this school? I haven't seen Julia since September. Tip! For other uses of the Present Perfect tense, see the Present Perfect Tense - When To Use. We use for with a period of time, for example: a few days, half an hour, two years. We use since with the time when the action started, for example: last year, June 8, I met you. Each of these present perfect sentences contains a time expression. Each time expression is a length of time (which requires FOR) or a starting time (which requires SINCE). 1 Maya has been a professional ________ 1989. 2 So far, it has rained ________ five hours. 3 I haven't been snowboarding ________ last winter. 4 Jo has been a student here ________ March. 5 The beaver has been an emblem of Canada ________ many years. 6 Cougars have almost disappeared from the Victoria area ________ humans settled here. 7 Mary has kept a diary ________ she was ten years old. 8 First Nations people in British Columbia have told stories about the eagle ________ hundreds of years. 9 The Canadian two-dollar coin (or toonie) has been in circulation ________ 1996. 10 They've been married ________ twenty-five years. 11 I haven't phoned home______ Christmas. 12 We've been here__________ nine o'clock. 13 I have worked for International House__________ more than eight years. 14 I haven't visited my home town_________ I left school. 15 I haven't been to the cinema__________ ages. 16 I have studied non-stop_________ 9.15. 17 I have had a driving licence_________I was eighteen. 18 She hasn't had a day off _________1999. 19 Johan has been in England__________more than two weeks now. 20 Peter has been my best friend_________ we were nine. ■Closing down by deciding if you need for or since with these time expressions. ---for/since last weekend ---for/since ten seconds ---for/since Christmas Eve ---for/since a decade ---for/since I finished school ---for/since a couple of days ---for/since my birthday ---for/since a long time ---for/since ten centuries ---for/since the 70s ---for/since I was a boy ---for/since August ---for/since the last month ---for/since fifteen years ---for/since the accident ---for/since then ---for/since we bought this house ---for/since last month ---for/since a millennium ---for/since I met you 111
