Question

Did you get your homework is finished all right

Answer 1

原句谓语动词get的用法错误，应该是get sth done，即过去分词finished前面不能再有is，去掉才正确。
Did you get your homework finished? 你做完家庭作业了吗？

Answer 2

整个句子需要纠正一下：
Did you get your homework finished? 你做完作业了吗? (= Did you finish your homework?）
此句话中用了使役动词get的短语：get sth. done ”让某事被做“（done 为补足语）
get 是使役动词”使，让“，your homework 是宾语， finished是补足语

Did you get your homework all right? 你的作业完成得好吗?
结构与上句相似，all right 是补足语

finish 和all right不能一起搭配起用，只好拆开来用。
