not .until直到.才 时态用法会的来

你的这句是正确的,前边如果一般现在时的话后面也是一样,如果是过去式的话那么后面也是过去式。也就是前V过去=后V过去。前V现在=后V现在。until直到。。。时, 到。。。为止例句:I couldn't sew until I was six。 我直到六岁时才会用针缝东西。We can't start the job until we have the approval from the authority concerned。 没有有关当局的批准我们不能开始这项工作。He waited until the volcano became quiet and he was able to return two days later。 他一直等到火山平息下来,两天后他才得以重回火山上。
