直到……才的英文：until。
相关用法：
1、until用在肯定句,谓语动词通常是延续性动词,如stand, stay, talk, wait等,表示主句动作终止的时间。
I waited until he came back.
我一直等到他回来。
2、如果用在否定句，谓语动词通常是瞬间性动词,如open, start, leave, arrive, finish, stop等,强调主句动作开始的时间。

直到这孩子的母亲来,我才离开。
3、连词until引导的从句中谓语动词的时态
（ 1）until后面的从句中不能用一般将来时，应该用一般现在时代替。所谓的“主将从现”。

我要完成作业才睡觉。
（3）主句中的谓语动词为一般过去时时，从句中的谓语动词为过去完成时，用来强调从句谓语动词的动作发生在主句谓语动词表示的动作之前。
