until和not…until的用法

Answer 1

until
/
not...until之间的区别：
until“直到”,表示某一种行为一直持续到某一时间。用在肯定句中，句子的谓语动词必须是可延续性的。
not...until“直到...才”表示直到某一时间,某一行为才发生,之前该行为并没有发生.
用在否定句中，主句中的谓语可以是延续性的也可以是短暂性动词，No
until放在句首的时候要倒装，并且，是『前不倒后倒』。前不倒后倒啥意思？？
这个意思：Not
until
I
got
home,
did
I
found......
这个要区别于：『前倒后不倒』的几个特殊例子：
not
only
but
also
no
sooner
than,hardly
when.....就这三个特殊
1.

还可以用于强调句中，也可以放在句首，句子要采用部分倒装

Until直到….为止,
not
until直到…才
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。
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

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。
否定句可用另外两种句式表示。
(1)Not
until
…在句首，主句用倒装。

until
the
early
years
of
the
19th
century
did

Not
until
I
began

work
did
I

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…这是一个强调结构。如本题。
Till的用法基本相同，但
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。
希望对楼主有帮助！

Answer 3

两个不能说区别，因为not
until本来就是until的否定，表示直到··才··
意思上：
until
（直到··开始·做·）
not
until（不做··直到··时候）
He
came
back
until
midnight.
他直到夜里才回来。
He
did
not
go
until
night.
他直到夜里才走。
（到夜里之前没有走）
用法上：
until表示的意思是"做某事直至某时"，动词必须是延续性的。
not
until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。
另外：
until一般不放在句首，后面跟时间词连用
如：He
came
back
until
midnight.
not
until:可放句首，但主句要用倒装．
Not
until
midnight
did
he
came
back
home.
还有一种用法与until相似．
He
did
not
come
back
home
until
midnight.
until
prep.
(=to
the
time
of)直到...时,
到...为止
[常用在否定句中](=before)在...以前;
直到...才;
不到...(不)
until
his
death
直到他死
until
four
o'clock
直到四点钟
It
was
not
until
yesterday
that
I
noticed
it.
直到昨天我才注意到这件事。
