until的用法
时间:2022-09-29 来源:养娃家
until可以用作介词和连词,可以翻译为到…为止、在…以前等。用法有:1、在含有until引导的时间状语从句中,如果句子(主句)的谓语动词是延续性动词(即动作可以延续一段时间的动词),如:work,live,stay,study,play,wait等,那么这个句子(主句)常常用肯定式,表示动作一直延续到until所表示的时间为止。这时until可译作“直到…为止”。例如:I'll work until he tells me to stop.我会一直工作到他叫我停下来为止。
2、在含有until引导的时间状语从句中,如果句子(主句)的谓语动词是非持续性动词(即动作一会儿就结束的动词),如:come,go,leave,begin,start,finish等,那么这个句子(主句)常常要用否定式,表示某一动作到until所表示的时间才发生。not…until…意为“直到…才…”。例如:She didn't go to bed until she finished her homework.她直到做完作业,才去睡觉。
3、until用作连词引导时间状语从句时,从句表示的如果还没有发生,习惯上也要用一般现在时而不用一般将来时,也就是说当主句用一般将来时(或主句是祈使句时),until引导的时间状语从句要用一般现在时。例如:Don't leave until we come back.在我们回来之前,不要离开。
