You can't borrow books from the school library ____ you get your student card.主从复合句

问题描述:

You can't borrow books from the school library ____ you get your student card.
主从复合句

until, brfore 都可以。是时间状语从句。

我觉得该填where,因为修饰的词语是library,书店,这是个地点

until
直到 才
直到你拿到学生证 你才可以从图书馆借书
我的肯定是正确的

可以填except
Only when
Only in the case that

except

until
not,,,until 直到,,,才

until, before都可以
上面那些什么except,unless,表达都是很不地道的。

unless
until
before
都可以~

unless
