"he is finish with clothes"可以这么用吗?如不可,用“be finish with”造个句子

he is finish with clothes句子不对要改为he is finished with the clothes或he is finished with his clothesis finished with something = 做了/穿了/结束了/完成了...（某事情/某东西）finished 这里是形容词句子..."fininsh"后为何要加“ed"“be finish with sb"呢？？finish 是动词，不是形容词，be finished with 词组里 finished 是形容词，必须用 -ed 的形式。上面提供了一些其他 动词 + ed 用作形容词的单词例子。我是加拿大人，前英语老师。？？？加拿大人？中文这么好？？？
