until的语法用法初中

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. 那也许会持续到周五。 (until用作介词)

There will be a wonderful match tonight. I will watch it until it finishes.

今晚有一场精彩的比赛。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,不会持续。

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. 直到你解释了以后我才会做。

(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...(注意that从句中谓语不能再用否定。)

It was not until late in the evening that her husband 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/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。(注意: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 husband arrive home.直到很晚的时候她的丈夫才回到家。

(注意: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.)

下面再看这个句子

He didn’t understand me until I told it to him.直到我告诉他才明白我的意思。

这里didn’t understand是主句的复合谓语,把它改成倒装句时,只把did提前,understand不能提前,主句改为肯定句。为Not until I told it to him did he understand me.

改为强调句It was not until I told it to him that he understood me.直到我告诉他才明白我的意思。

我们再来看个句子:Until that happens, you need to protect yourself.

在那之前,你必须保护你自己。(这里until 从句提前,主句不倒装。只有not until放在句首,后面才倒装。)

我们再来翻译一个句子:直到地震两周后他才发现他的妈妈活着。

Not until two weeks after the earthquake did he find his mother alive.

(he后面的发现不能用found,必须用原形find。)

直到她妈妈给她读了一个故事这个小女孩才睡着。

Not until her mother read her a story did the little girl fall asleep.

或者 The little girl didn’t fall asleep until her mother read her a story.

例句You can’t have this football back until you promise not to kick it in class.

直到你保证不再上课时踢球你才能拿回这个球。

改为倒装句Not until you promise not to kick it in class can you have this football back.

直到你保证不再上课时踢球你才能拿回这个球。

改为强调句It is not until you promise not to kick it in class that you can have this football back.直到你保证不再上课时踢球你才能拿回这个球。
