before和until有什么区别么?这里能用until么?
"Larry,I can't give you an answer ____ I think it over," said joe.
before
until
虽然我before填入很通顺,但我觉得until也没错误吧?

until如果用在肯定句中,则主句的动词必须是延续性动词.until是终点,指这个动作或状态一直延续到until的时间为止.
I waited until he came back 我一直等到他回来.
until 用在否定句中,主句动词是非延续性动词（换句话说,如果主句动词是非延续的就要用否定）,until是起点,指这个动作在until的时间才开始
I didn't leave until he came back 直到他回来我才走
楼上I can only give you an answer until I think it over.这个句子是错误的.
在这道题里其实并不强调“我不给你答案”这个状态的延续,而是强调在考虑之前“不能”给你答案,所以该用before,说明先想想再告诉你
