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。
I didn't leave the boy until his mother turned up.
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”。
He will stay here until his mother comes back.
（2）主句的谓语动词为一般现在时或一般将来时时， until从句中的谓语动词为现在完成时，用来强调从句谓语动词表示的动作发生在主句谓语动词表示的动作之前。
I won’t go to bed until I have finished my homework.
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。
Li Lei didn’t come until the film had begun.
