i was finished i am finished 和 i was finish

i was finished i am finished 和 i was finish I am finished. I am finished when I am finished会错吗? I was finished my work.I finished my work.What's the differe 请问I have finished my work 和I am finished my work i am finished和i have finished倒底一样不一样 It was a little tire after I finished my work.. I finish 可以单独成为一个句子吗?与 I am finished 有什么区别嘛 I am finished 这里为什么要用be finished? 可是说i am finished吗? i am already finished watering them
