until ,till和not untill有什么区别?
till / 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：
He didn't go to sleep until 12 last night .
他昨晚直到十二点钟才睡觉.
They didn't realize their fault till 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.
但是,当主句是肯定句时,它引出的意思是"直到（某时某动作停止了）" .例如：
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.
The young couple were very happy until they used up all their money .
那对年青夫妇直到花光了所有的钱才沮丧起来.
另外,until 可以放在句首而till则不行.我们可以说：Until they used up all their money,the young couple were very happy .我们却不可以说：Till they used up all their money,the young couple were very happy .
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".动词为延续性或非延续性都可 以.正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式.
肯定句：
I slept until midnight.我一直睡到半夜时醒了.
Wait till I call you.等着我叫你.
（在肯定句中可用before代替 Let's get in the wheat before the sun sets.）
否定句：
She didn't arrive until 6 o'clock.
她直到6点才到.
Don't get off the bus until it has stopped.
公共汽车停稳后再下车.
I didn't manage to do it until you had explained how.直到你教我后,我才会做.
1)Until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.
2)Until 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.
(1）Not 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…

Until then, I knew nothing at all about it.
在那时以前, 我对这事一无所知。
用法
USAGE: In most contexts, till and until have the same meaning and are interchangeable. The main difference is that till is generally considered to be more informal than until. Until occurs much more frequently than till in writing. In addition, until tends to be the natural choice at the beginning of a sentence: until very recently, there was still a chance of rescuing the situation. Interestingly, while it is commonly assumed that till is an abbreviated form of until (the spellings 'till and 'til reflect this), till is in fact the earlier form. Until appears to have been formed by the addition of Old Norse und (‘as far as’) several hundred years after the date of the first records for till.

语言是不断发展和更新的工具，在以往较为强调until以及till的区别，不过在现代英语中，until和till的区别已经渐渐模糊，不再强调。二者皆为直到的意思。但要注意句首只能用until，until较为常用。
not……until……直到……才……
前半句用否定。例如：That baby didn't fall asleep until his mother came back....

前半句用否定。例如：That baby didn't fall asleep until his mother came back.
直译的话：那个婴儿直到妈妈回来之前没有睡觉。但是，在高考中，直译是不能拿到翻译题全部的分数，所以翻译要汉语化，要练习：那个婴儿直到妈妈回来才肯睡觉。

until和till两者都可作介词、连词，一般情况下可以互换使用。用于肯定句时，主句的动词只用延续性的，它所表示的动作一直延续到till或until表示的时间为止，意为“直到……为止”；用于否定句时，主句的动词一般是非延续性的，也可以是延续性的，它所表示的动作直到till或until所表示的时间才发生，意为“直到……（才）”。如：
肯定句 She watched TV until / t...

肯定句 She watched TV until / till her mother came back. 她看电视直到她母亲 回来。（看电视的动作延续到母亲回来才结束）
否定句 She didn”t watch TV until / till her mother came back . 直到她母亲回来她 才（开始）看电视。（看电视的动作直到她母亲回来才发生）
1. until和till可以作介词或连词。作介词用时，后面接名词或副词；作连词用时，常用来引导一个时间状语从句。当它们用于肯定句中，主句动词常为延续性动词，表示这个动作一直延续到till / until所表示的时间为止。当它们引导时间状语从句时往往要用一般现在时代替一般将来时。如：
They worked until / till six o”clock.
他们一直工作到六点钟。
2. not until / till意为“直到……才”，主句常用终止性动词（即非延续性），表示until /till所表示的时间一到，该动作就发生。如：
He didn”t go to bed until / till eleven last night.
昨天夜里他直到十一点才上床睡觉。
Einstein was not able to return to his homeland until the war was over.
直到战争结束后爱因斯坦才得以回国。
注意：not until放在句首时要用倒装语序，Not until the war was over was Einstein able to return to his homeland.
3. 如果要放在句首，只能用until而不能用till，如：
Until I finished my homework, mother didn”t let me out.
直到我做完家庭作业妈妈才准我出去。
4.强调结构中也常常出现not until结构，常见句型为：It is / was not until…that。如下面这个句子：
She didn”t find me until I called her from behind.
直到我从后面叫她之后，她才发现了我。
改为强调结构：It was not until I called her from behind that she found me.
注：但在强调句型中，not until置于句首构成倒装句以及until放在句首时，均不能用till替换until。例如：
It was not until 1920 that regular radio broadcast began.
直到1920年才开始有定期的无线电广播。
Not until 12 o”clock last night did Tom come back.（倒装句）
昨晚直到十二点汤姆才回来。
Until I was 20 I had never been away from my hometown.
我二十岁以前，从未离开过家乡。
