You can't go out until your homework has been done.改倒装句.谢谢！
_________ your homework has been done __________.

Answer 1

倒装句要求把否定词及其相关的成分提前，然后把助动词/情态动词提前到主语前面。本句的否定词是not，相关部分是until从句，由此可以改写如下：
(Not until) your home work has been done (can you go out).

Answer 2

Unless your homework has been done, otherwise you can't go out.
除非已经完成你的作业，否则你不能出去。
