until的用法?
until意为“到…时,直到…为止”,既可以用作介词,又可以用作连词。
That may last until Friday. 那也许会继续到周五。 (until用作介词)
There will be a wonderful match tonight. I will watch it until it finishes.
今晚有一场出色的比赛。我要看完它。(until用作连词)
until的用法总结
1)用于肯定句,意为“到…时;直到…为止”,引导时间状语从句,主句谓语动词用延续性动词。
I will stay here until you come back. 我将呆在这里直到你回来。(stay是延续性动词)
Continue in this direction until you see a sign.一直沿着这个方向走,直到你看见一个指示牌为止。(主句是祈使句,continue是延续性动词)
He worked until it was dark. 他一直工作到天黑。(work是延续性动词)
2)用于否定句,not...until的意思是“直到…才”,引导时间状语从句,主句谓语动词一般用短暂性动词。短暂性动词就是瞬间完成的动词,如go,come,leave, die, arrive,buy, enter等, 以enter为例,我们“进”这个动作一瞬间就完成了,不会继续。
I hadn’t realized she was foreign until she spoke. 直到她讲话我才意识到她是外国人。
(realize是短暂性动词)
I didn’t manage to do it until you had explained now. 直到你阐明了以后我才会做。
(manage是短暂性动词,manage to do something努力做某事,设法做某事,设法做成某事)
He didn’t leave the office until he finished his work.他完成工作才离开了办公室。
(leave是短暂性动词)
3)Not...until的强调句式:It is/was not until... that...(注重that从句中谓语不能再用否定。)
It was not until late in the evening that her hu *** and arrived home.
直到很晚的时候她的丈夫才回到家。
It was not until it stopped that we got off the bus. 直到公共汽车停下我们才下车。
4)Not...until的倒装句句式:Not until ...+助动词/系动词/情态动词+主语+其他。
即:not until+词组放在句首时,后面谓语部分要使用部分倒装,即只把谓语部分的助动词/系动词/情态动词提前,而谓语部分的实义动词依然放在主语的后面;not until+从句放在句首时,后面的主句谓语部分要使用部分倒装,并且主句不能再用否定。(注重:从句不倒装)
将上面的两个例句改成倒装句
Not until late in the morning did her hu *** and arrive home.直到很晚的时候她的丈夫才回到家。
(注重:这里arrived要变成原形,前面要使用助动词did。)
Not until it stopped did we get off the bus.直到公共汽车停下我们才下车。
(这里主句使用助动词did,got off 变成原形get off.)
