not until,as soon as,if所引导的状语从句,分别有哪些时态形式?

B.Not until next week.
问的是你什么时候走,
A是说“到下星期之前”,并没有回答问题,下星期前要做什么没有说.（不过如果答案是“I will not return to the USA until next week"就也是可以的,因为说明了下星期前不会走,回答了什么时候走的问题.）
B是“下星期前不会”,就是下星期或之后才走,回答了问题.
C是“几天前”.既然问句是将来时,回答者还没回去,事情还没发生,这个回答当然是不成立的.

C 应改为：knew
这是一个对时间状语从句进行强调的强调句,所叙述的一件发生在过去的事情,故主句中应用一般过去时,而不用过去完成时.

标准答案C
因为not,until提前,所以,句子用倒装
原来的是：
the workers didn't,decide to go on strike until all the demands had been turned down
这里until引导的是时间状语从句
前面是主句
现在的格式是
not+until引导的从句,+主句的一般疑问句（去除not）
你要记住这个公式

后面not until sb did sth,did sb do sth

A

考查：Not until放在句首使用部分倒装，从句不倒装，主句倒装。故选A。

选 D.
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.
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 we pointed their fault out to them, did they realize it.
当我们指出他们的错误之后,他们认识到了自己的问题.
而题中原句为：The scientist didn't to back to his lab until the war was over.
其主句是 The scientist didn't to back to his lab ,要倒装
为,did the scientist go back to his lab, 为表强调,将not until the war was over, 放在前面.

not until 句型有点难度,要耐心学习啊
元旦快乐,学习进步

因为 主将从现
完整句子是
Not until the work is finished tomorrow shall we go to watch the basketball match in the sports centre

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。 not until we finished our work did he come not until midnight did he return 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. 因此呢，现在的用法属于not until 的强调结构。这种用法很常见哦！

not until you finish your homework can you go out playing.

until 直到.为止
He taught me English until the class was over.
他教我英语,直到下课为止.
not until 直到.才
It was not until the class was over that he began to teach me English.
直到下课之后他才开始教我英语.

不是的,这是接持续性动词的
not until 是在...之前
如:You can not go against it until you can earn your life .
not until:可放句首,但主句要用倒装．
Not until midnight did he came back home.

没有固定的时态,可以根据具体情况而定.我举几个例子说明：
一般过去时：I didn't go to bed until I finished my homework.(我直到写完作业才睡觉）
一般将来时：I won't leave until he comes.(直到他来我才离开）
但until后一般用过去时或一般现在时.

Until he failed the exam, he realized how worse the matter.

Not until I saw the score did I realize I hadn't work hard.
直到我看到分数,我才意识到自己没有努力学习
I realized I hadn't work hard是主句,倒装就成了did I realize ...
Not until I saw the score 是状语从句,不用倒装

你说错了,not until,as soon as所引导的都是时间状语从句,if,unless所引导的都是条件状语从句.时态要注意“主将从现”,即主句用将来时,从句用一般现在时.He will not go to bed until his mother comes back.He will...

主句的谓语动词是非延续性动词时,用否定形式表示主句的动作直到until所表示的时间才发生,构成句式not until

not … until,until
A.until表示动作、状态的持续,强调“一直到……为止”,或强调某个动作或状态一直持续到另一个动作或状态出现之前.常与表示延续性动作的动词连用.
如：* I waited until three o’clock,but he didn’t come.* He lived with his parents until he graduated from college.
B.not … until表示“到……为止；直到……才”,常与表示瞬间性动作的动词连用.
如：* The noise of the street didn’t stop until midnight.* The children didn’t come home until it was dark.* I didn’t know the truth until you told me.

not until 直到┅才
not…until …直到才
这样说就明显了

不可以的, that 后面的句子he wasn't go to bed 是个严重的语法错误,再说一般英语里说法否定要放在前面的

until是知道的意思，具体用法要根据句意，not until 是直到。。。。才，前半段为否定，后面加until 例句:He didn't go to bed until his mother go back 他直到他妈妈回来才去睡觉

其实同not...until是一样的,只不过否定前移需倒装,Not until 5 o'clock did he come back home.=He didn't come back home until 5 o'clock.
until一直到...,not until直到...才.../...之前没做...
Wait until I call you.(一直等到我打电话给你）
He didn't come until 5 o'clock.(直到5点他才来/五点之前他没来）
People didn't find that kind of animals until 19th century

not until +.
只能作为状语,因而不可能加谓语或非谓语.

那是否定句
这是陈述句

till

不需要

看QQ没～～～～
过了很久之后,她才怀疑自己是否犯了错误…………
not .until翻译成“直到.才.”,not前面的动词是瞬间性动词
until单独出现的时候前面要加 延续性动词,翻译成,“在.之前一直做.”
就记住翻译的意思就好～～～～～～～～否则容易混淆呢
不过值得注意的是这个哦
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
还有一点：像你这个要翻译的句子一样：not until用于强调句的时候不倒装～～～～～～～～～～～～～～～～～～～不倒装哦!
果果要求追加分数～～～～～～人家大半夜跑上来回答这么笨笨的问题

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 my mother called me did I go home。

not until 是在...之前 用于非延续性动词
如:He didn't come back until 9 o'clock.

c.It was not until long afterwards that
直到很久后她才开始想到自己是不是犯了一个错误.
强调句.
原句是：She did not wonder if she had made a mistake until long afterwards.
对这类not..until句型中until引导的时间状语进行强调时,要把not放在until前一并进行强调.

亲爱的楼主：
He didn't come back until 9:00.
他直到9点才回来.
祝您步步高升
期望你的采纳,谢谢

Not until she took off her glasses did I realize she was a famous actress.
I did not realize she was a famous actress untill she took off her glasses.

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.
因此呢,现在的用法属于not until 的强调结构.这种用法很常见哦

I didn't gei up until 9:00.
我直到9：00才起床

After left until he saw in the diary of the study, I realized that that day he may do so on purpose

not until came back did I know.

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.
1. I studied Englis until 9 o'clock last night.
我咋晚学英语一直学到9点钟.(表示9点前一直在学)
2. I did not study Englis until 9 o'clock last night.
我咋晚直到9点钟才学英语.(表示9点才开始学)
3. I waited for five hours until it was dark. I had to give it up.
4. I didn't go to sleep until 11 o'clock
not until 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
5. It was not until he came back that I went to sleep
6. Not until he came back did I go to sleep.

直到1920年,常规电台才正式开播!如果句子 不是There 而是 IT的话 这就是not ...until的强调句型了 not until 引起的时间状语置于句首时,句子的主谓应部分倒装.由 not until 引导的时间状语从句位于句首时,主句应部分倒装,从句语序不变.如：Not until 1998 did he return to his hometown.直到1998 年他才回到家乡.Not until Father came back did we begin to have supper last night.昨晚直到父亲回来,我们才开始吃晚饭.注意：当 not until 引导的状语或状语从句用于强调句型时,句子的主语不倒装.如将上两句改为强调句应为：It was not until 1998 that he returned to his hometown.It was not until Father came back that we began to have supper last night.

He didn't come back until 9:00.他直到9点才回来.
He worked until 9:00.他一直工作到9点.

A,按照主将从现,we cannot have dinner until it is prepared in half an hou

xuan B

应该填stopped
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.
直到电影开演,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.

1so...that 句式中不用倒装.
2:Seldom do i go shopping by taxi unless the day is rainy.最后一个单词应该是rainy,这样是对的
3 Not until I checked the answer did i detect a big problem 动词应该用detect,这样是对的

否定词倒装的话,主句助动词前置在主语前面.
so...that 句式中不用倒装.So的倒装如下
She danced. So did I.表示我也这么做了 So替代前面的动词dance,表示（也同样）做
She told me to dance and I did so. 这句不倒装是因为不是同样做,

【Me YC诚心为你解答此题,

Why not we have lunch first我们先吃中饭吧

He didn't sleep until his mother returned home 知道他妈妈回到家他才睡
He is considering doing it or not 他正在考虑做不做

not...till till其实是和until差不多的意思,但前面用not的话并不是解释为直到...才,而是直到...还没.
He didn't come till 5 o'clock

C

从后面的did man accept可以看出not until后面连接的是一个时间状语从句，不能用倒装句；同时也应该判断出，many years的流逝是发生在accept之前的，所以这个时间状语从句应该用过去完成时态。句子的意思是“直到很多年过去，人们才接受这么个事实：一切生物都是要死亡的”

好 这里说明下 强调句 强调的是 那个部分?应该是强调的是 it be 后面的
that后面是辅助成分
既然前面是it was not 那理所应当 他的反仪疑问句应该是 was it 选B

基本一样.
not until连一起,一般起强调作用,通常有强调句式.
