这句话若要改成before连接句子怎么改?

A.before B.until C.where D.as
请问下面的
Before your work is done,you may not (can not)go out.这里的before从句必须放前面吗？
如果可以放后面,那这道题的答案不就是A,B了？有没权威点的语法解释啊。
找到一个比较权威的语法解释:
希望对以后有同样问题的人有用:
不少的语法书上说，before引导的从句习惯上不与否定的主句连用，要用until。实际上二者都可以，有时在意义上有些区别。试比较：
He didn't arrive until I returned.直到我回来时他才到达。
He did not arrive before I returned.在我回来之前他尚未到达。
I didn't manage to do it until you had explained how.直到你解释了如何干，我才设法完成了那项工作。
I didn't manage to do it before you had explained how.你解释了如何干之后，我才设法完成了那件工作。

You may not go out until your work is done.这句话若要改成before连接句子怎么改?You may not go out___your work is done.A.before B.until C.where D.as请问下面的Before your work is done,you may not (can not)go out.这里的before从句
before your work is done,you may not (can not)go out.
在此 应该选择until 因为 前面又个 not ,从而构成了个 not until的句型.
随便你放哪里 自己喜欢 我比较喜欢放前面.但是 这里有个not 所以最好的选择就是选择until 构成短语
如果你是做题 ,题目绝对是叫你选择最佳的答案拉,until就是最佳的.完毕!

You must not go out before your work is done.

You may not go out before your work is done

You may not go out before your work is done

Before your work is done, you may not (can not)go out.
