Причастие в пассиве (Passive participle). Если предмет или человек выполнял действие не самостоятельно, а действие выполнялось над ним. The leaf has gone by the wind gone by the wind - унесенный ветром gone by the wind ============================= I was in Pskov == я САМ был в ПСКОВЕ (по моей воле, сам приехал и уехал) I HAVE BEEN to Pskov == Я ПОБЫВАЛ (не по моей воле, например вместе с родителями там побывал, или по принуждению) ============================= I has done - я сделал I am done - Я ВСЕ or “I am done with” means: I have reached the end, have completed or finished with any activity that one is presently doing or engaged in or with. It can also mean “I am fed up” with some one or something, or “I am full” in matter of eating. While both I'm done and I'm finished are correct, common, and generally accepted, I'm done is by far the more popular choice. Some grammar sticklers might argue that the best construction is I have finished, but this sounds a bit formal and stuf
