untill和till的区别和用法

till /和until在表达方式和意义上的特殊性:until是till的强调形式,但是它们

表达的意义是相同的,都表示"直到某时".不过,当主句是否定句时,它引出的意思

是"直到某时某动作才发生" ,这时候常会出现"not until …"的结构,如果将 "not

until …"的结构放在句首,那么主句要写成倒装句.例如:

They didn't realize their fault untill we pointed it out to them .

直到我们向他们指出了他们的错误,他们才意识到.

Not until we pointed out their fault to them did they realize it .

直到我们向他们指出了他们的错误,他们才意识到.

The students made much noise till the teacher came into the classroom .

直到老师走进教室学生们才停止了大声喧哗.

基本结论:

因此此两个连词意义相同.肯定形式表示的意思是"做某事直至某时",动词必须是

延续性的.否定形式表达的意思是"直至某时才做某事".

1Until可用于句首,而till通常不用于句首.

Until you told me, I had heard nothing of what happened.

直到你告诉我以前,出了什么事我一点也不知道.

2Until when 疑问句中,until要放在句首.

---Until when are you staying 你呆到什么时候

--- Until next Monday. 呆到下周一.

注意:否定句可用另外两种句式表示.

1Not until …在句首,主句用倒装.

Not until the early years of the 19th century did man know what heat is.

直到19 世纪初,人类才知道热能是什么.

Not until I began to work did I realize how much time I had wasted.

直到我开始工作,我才认识到了我已蹉跎了几多岁月.

2 It is not until… that…

3用于“”的句式可以转换成when 或after引导的时间状语从

句,但主句必须要用肯定形式.例如:

They didn't get off until the train came to a complete stop.=They got off

after the train came to a complete stop. 火车停了他们才下车.

4 用于“It is / was hat”或含有“”的强调结

构中,其中的until不能改为till.例如:

1. It was not until the film had begun that he arrived. 直到电影开始他

才到.

2. It is not until 8:00 that we begin our class every day. 我们每天八

点开始上课.

注:某些固定词组或谚语中通常只用till.例如:

1. from morning till night 从早到晚.

2. up till now直到现在
