till和until的用法区别
一、在含有until引导的时间状语从句中,如果主句的谓语动词是延续性动词,如:work,live,stay,study,play,wait等,那么这个主句常常用肯定式,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。
二、在含有until引导的时间状语从句中,如果主句的谓语动词是非持续性动词,如:come,go,leave,begin,start,finish等,那么这个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。
三、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。

until的用法和短语
关于这个问题,请参考《
中学英语高频词详解词典
》(金盾出版社),这是我见过的最好,最详细的说明,特与你分享:
Until用法详解
表示“直到……为止”,两者常可换用,只是
until
比
till稍正式,所以在正式文体中,一般用
until,
而在口语或非正式文体中则两者都可用。从其后所接成分来看,till多与名词或较短的从句连用,而较长较复杂的成分多用
until,
位于句首时也多用
until。两者在用法上应注意以下几点:
1.
相关主句谓语必须是
持续性动词
,若是终止性动词,则应为否定式(因为终上性动词一旦被否定就成为状态,便可持续)。如:
He
waited
until
she
was
about
to
leave.
他等着一直到她准备离开。
She
didn’t
marry
until
she
was
over
fifty.
她直到50多岁才结婚。
2.
引导
时间状语从句
时,其谓语要用现在时表示将来意义。如:
I
won’t
leave
until
he
comes
back
tomorrow.
我要等他明天回来后再走。
Continue
in
this
direction
until
you
see
a
sign.
一直朝着这个方向走就看见
指示牌
了。
3.
有时其后可跟副词或介词短语等。如:
He
has
been
ill
until
recently.
他最近一直生病。
Until
when
are
you
going
to
stay
here?
你在这儿
要待到什么时候?
We
didn’t
eat
till
past
midnight.
直到午夜过后我们才吃饭。
She
won’t
go
home
until
after
the
exam.
她要考完试之后再回家。
如果语境的需要,有时甚至可以接带有“引导词”的从句。如:
Don’t
leave
until
after
I’ve
spoken
to
you.
我和你说完后再离开。
4.
用于
not…until
[till]…结构
(1)
若主句动词为终止性动词,其意为“直到……才……”;若主句为持续性动词,其意为“不到……就……”。比较:
They
didn’t
find
her
till
the
next
day.
他们直到第二天才找到她。
He
didn’t
wait
until
I
returned.
他没等到我回来(没等我回来他就走了)。
有时
until
或
till
可以换成
before。如:
Until
[Before]
you
told
me,
I
had
no
idea
of
it.
在你告诉我之前,我对此一无所知。(即直到你告诉我,我才知道)
(2)
可用于It
is
(was)
not
until
[till]…that…这样的强调句型。如:
It
was
not
until
I
met
you
that
I
knew
real
happiness
.
直到我遇到你以后,我才真正担长曹短丨的查痊肠花体会到幸福。
It
was
not
until
she
took
off
her
dark
glasses
that
I
realized
she
was
a
famous
film
star.
直到她取下墨镜,我才意识到她是一位著名影星。
(3)
若将not
until
[till]置于句首,其后的主句要用倒装语序。如:
Not
until
much
later
did
she
learn
who
her
real
father
was.
她很久以后才知道她真正的父亲是谁。
Not
until
he
received
her
letter
did
he
fully
understand
the
depth
of
her
feelings.
他直到收到她的信之后才充分理解她的感情有多深。
until用法
until 的用法 一, 介词 until 作介词的 until 的英文解释是 up to a specified time (直到某一时刻)或 up to the time of a specified event (直到发生某事).但注意观察下列句子,我们还可留意到 until 在具体运用中 的细微之处. 1. 用于肯定句中: 1) It may last until Friday. 这可能要延续到星期五. 2) He will be working until 5 o'clock. 他将一直工作到五点钟. 3) She was a bank clerk until the war, when she trained as a nurse. 她战前是个银行职员, 战时 受训当了护士. 不难看出 until 用于肯定句中,表示句子的动作一直持续到 until 短语所表示的时间为止, 即表示动作的终点.一般可译为"直到……时(为止)"或"在……以前" .在这种用法中, 句子的谓语动词必须是持续动词(非瞬间动词),如 live, wait , last, love, like, stay, work, continue 等. 二, 连词 until 以同样的方式分析作连词的 until 的用法.作连词用的 until 的英文释义是 up to the time when(直到……时为止). 1. 用于肯定句中: 1) Heat can be conducted from a hot body to a cooler one until both are at the same temperature. 热可以从一个热的物体传到一个较冷的物体,直到两者温度相同为止. 2) Continue in this direction until you see a sign. 一直朝着这个方向走就会看见指示牌了. 3) He ran until he was breathless. 他一直跑到气喘吁吁才停下. 不难看出,作连词的 until 用于肯定句中,表示主句的动作一直持续到从句动作发生或状 态出现时为止.一般可译为"……直到……为止" .在这种用法中,主句的谓语动词必须是 持续动词(非瞬间动词),如 live, wait , last, love, like, stay, work, continue 等. 2. 用于否定句中: 1) I hadn't realized she was foreign until she spoke. 她不说话我还一直不知道她是个外国人. 2) I won't stop shouting until you let me go. 你不放我,我就一直喊叫. 3) Among the great mathematicians there are about as many who showed mathematical talents in childhood as there are those who showed none at all until they are older. 在伟大的数学家中, 童年就显露数学才华的人和直到相当年龄才显露才华的人差不多一样多. 不难看出, 作连词的 until 用于否定句中, 从句先发生, 主句再发生. 一般可译为 "直到…… 才" .
attention:一,until与by的区别 1. by表示在某特定的时间之前或不迟于某特定的时间,意为"最迟在;不迟于"或"在……之 前"等.如: ①I will finish my task by nine.我将在九点钟前完成任务. ②The plane takes off at 10:00, so you must try to be at the airport by 9:30. 飞机在十点钟起飞,所以你必须在九点半赶到机场. 2. until用在肯定句,谓语动词通常是延续性动词,如stand, stay, talk, wait等,表示主 句动作终止的时间.如: ③I waited until he came back.我一直等到他回来. ④The war lasted until 1945.战争持续到1945年. 如果用在否定句,谓语动词通常是瞬间性动词,如open, start, leave, arrive, finish, stop等,强调主句动作开始的时间.如: ⑤I didn't leave the boy until his mother turned up.直到这孩子的母亲来,我才离 开. ⑥The noise of the street didn't stop until it was midnight.街上的噪音直到半夜 才停止. 二,until与before的区别 1.可直接换用的情况:在until能使用的句型中,即主句含有否定式终止性谓语动词或肯定式 延续性动词,可与before直接替换,意义差别不大.如: ①The students won't go home until / before they finish their homework.学生们 要先完成作业才能回家. ②The woman worked in the factory until/before 1990. 1990年以前这妇女在这家工 厂上班. 2.不可换用的情况:当主句含有肯定式终止性谓语动词时,只能用before不能用until,且 before常意为"没来得及……"或"……才……"等.如: ③Einstein almost knocked me down before he saw me.爱因斯坦差不多将我撞倒才看 见了我. ④He had measured me before I could get in a word.我还没来得及插话,他就把我的 尺寸量好了.

not until和until的区别
not until/until两者皆可接延续性动词和暂短性动词。
一、not...until指的是“直到...才”的意思,如 I did not go home until my mother called me.
我直到我妈妈打电话给我才回家。
not until的倒装与强调结构
1.当Not until位于句首时,句子要倒装。其结构为:Not until+从句/表时间的词+助动词+(主句)主语+谓语+...。如:
①Not until the teacher came in did the students stop talking.直到老师进来学生们才停止讲话。
②Not until next week will the sports meet be held.直到下周才开运动会。
2. not until的强调结构为:It is / was not until+从句/表时间的词+that+...。
上面两句改为强调句为:
③It was not until the teacher came in that the students stopped talking.
④It is not until next week that the sports meet will be held.
直到我结婚的时候,我才有钱买了自己的房子。
It was not until I got married that I could afford to buy a house of my own.
而until指“直到”。例如:
Go alone the street until you see the traffic light.
往前走,直到你看见交通灯。
