可是说i am finished吗?

可是说i am finished吗? I am finished. I am finished when I am finished会错吗? i was finished i am finished 和 i was finish I am finished 这里为什么要用be finished? i am already finished watering them I finish 可以单独成为一个句子吗?与 I am finished 有什么区别嘛 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 I am finished drinking.请问这句是什么时态. I have finished my homework.可否这么说 I finished my homework.为什么
