释义:直到半夜雨才停下来。
例句:It was not until five o'clock in the afternoon that they finished their work.?

not until的用法
until可用作介词或连词,意为“到……时候为止”、“到……时候才”或“在……时候以前不”。什么情况下表达什么意思,关键要看(主)句中的谓语动词是终止性动词还是延续性动词。
1.
如果(主)句中的谓语动词是终止性动词,应采用“...
not
...
until
...”结构,意为“……到……时候才……”。例如:
You
mustn’t
eat
anything
until
you
see
the
doctor.
看过医生之后,你才能吃东西。
Don’t
get
off
the
bus
until
it
has
stopped.
车停稳了以后再下车。
2.
如果(主)句中的谓语动词是延续性动词,那么谓语动词用肯定式或否定式,它们所表达的意思有所不同。
1)
如果谓语动词为肯定式,则until译为“到……时候为止”。例如:
I
watched
TV
until
she
came
back.
我看电视一直看到她回来。
2)
如果谓语动词为否定式,则until应译为“到……时候才”,即“在……以前不”。例如:
I
did
not
watch
TV
until
she
came
back.
(=
I
began
to
watch
TV
when/after
she
came
back.)
直到她回来我才开始看电视。
3.
用终止性动词作谓语时,
until既可以和not连用,又可以和never,
nobody,
nothing,
few,
little,
seldom,
hardly等含否定意义的词连用。例如:
I
had
not
seen
him
until
1990.
(=
I
had
never
seen
him
until
1990.)
1990年以前我从未见过他。
Don’t
put
off
until
tomorrow
what
you
can
do
today.
(=
Never
put
off
what
you
can
do
today
till
tomorrow.)
今日事,今日毕。
4.
连词until引导的从句中谓语动词的时态。
1)
主句的谓语动词为一般现在时或一般将来时时,
until从句中的谓语动词为现在完成时,用来强调从句谓语动词表示的动作发生在主句谓语动词表示的动作之前。试比较:
I
won’t
go
to
bed
until
I
have
finished
my
homework.
我要完成作业才睡觉。
2)
主句中的谓语动词为一般过去时时,从句中的谓语动词为过去完成时,用来强调从句谓语动词的动作发生在主句谓语动词表示的动作之前。试比较:
Li
Lei
didn’t
come
until
the
film
had
begun.
直到**开演,李雷才来。
〔特别提醒〕
till和until的意思基本相同,用法也基本一样,但until语气较重,多用于较正式的文体里。
till多用于英式英语,
until多用于美式英语;
till不能用在句首,也不能用在not开头的短语或从句里,而until可以。例如:
Until
he
came
home,
we
knew
the
news.
在他到家之前,我们不知道这消息。
Not
until
nine
o’clock
yesterday
evening
did
we
finish
the
work.
直到昨晚九点,我们才完成这项工作。
not until 是什么从句
引导的时间状语从句否定句 not…until…直到…才…
(not 可以用表示否定意义的词代替,比如never,nothing, seldom等)
表示某动作一直持续到某时间才开始
(主句的谓语动词是非延续动词)
eg:Hewon’t go to bed till/until she returns.
Tom knew nothing about it untill hisI told him.
not…until (直到……才)的用法是?(要一个八年级学生能看懂的)
前边如果一般现在时的话后面也是一样,如果是过去式的话那么后面也是过去式.
也就是前V过去=后V过去.
前V现在=后V现在.
until直到...时, 到...为止
例句:
I couldn't sew until I was six.
我直到六岁时才会用针缝东西。
We can't start the job until we have the approval from the authority concerned.
没有有关当局的批准我们不能开始这项工作。
