第一篇：高考It++be++时间+++从句”结构总结

高考It +be+ 时间 + 从句”结构

总结一

在“ It +be+ 时间 + 从句”结构中，引导从句的从属连词有 before, that, since, until（till）, when 等。这一结构是近几年高考常考的知识点，现将它们的用法小结如下：

一、It +be（not）+ 时间段 +before 从句。

其中的主句是肯定式时，意为“过多长时间才„„”；主句是否定式时，意为“没过多久就„„”。例如：

1.It was not long before the whole country rose and drove the Austrian soldiers from their homeland.不久，全国人民便奋起反抗，把奥地利军队从他们的国土上赶了出去。

2.It may be five or six years before the new medicine is tested on human beings.要过五六年时间这种新药才能在人身上做试验。

3.It was two months before he designed the bridge.过了两个月，他设计出了这座桥梁。

二、It +will be（was）+ 时间段 +until 从句

若主句中用一般将来时，则从句中用一般现在时，意思是从现在起到从句中谓语动词表示的动作发生时还有多长时间；若主句中用一般过去时，则从句中也用一般过去时，意思是从过去某一时间起到从句中谓语动词表示的动作发生还有多长时间。例如：

1.It will be ten days until my birthday comes.到我生日还有十天。

2.It was only five minutes until her husband came back from work.当时离她丈夫下班只有五分钟了。

注意：结构“一”与结构“二”在肯定句中几乎可以通用。但是，若从句中谓语动词表示的将来动作一定或预期肯定会发生，则多用 until 引导从句；若从句中谓语动词表示的将来动作在客观上并非一定要发生时，则多用 before 引导从句。

三、It +is / has been（was）+ 时间段 +since 从句

在这一结构中，主句常用一般现在时、现在完成时或一般过去时。如果 since 引导的状语从句中的谓语动词为非延续性动词，则表示“自从状语从句中的动作发生以后，时间过不了多久”。例如：

1.It is two years since Jim came to China.吉姆来中国两年了。

2.It has been three years since they got married.他们结婚已经三年了。

如果 since 从句中的谓语动词为延续性动词，则表示“自从从句谓语动词表示的动作结束以来，时间已过了多久”。例如：

3.It is / has been a year since he smoked.他戒烟已经一年了。

四、It +is / was + 时间点 +when 从句

在这一结构中，时间之前没有介词，从句为 when 引导的时间状语从句。从句常用一般过去时，意为“当某事发生时，时间是„„”。例如：

1.It was October 1st, 1949 when the People's Republic of China was founded.中华人民共和国成立于 1949 年 10 月 1 日。

2.What time was it when you got to school?

你几点到的学校。

五.It is /was + 时间状语 +that 从句

这是一个强调句型，被强调的部分是时间状语。表示“正是在某个时间，某事发生了”。例如

1.It was ten years ago that he joined the army.他正是在十年前参的军。

2.It was yesterday afternoon that I met him in the street.就是在昨天下午我在街上遇见了他。

六、It is / was +first time / second time +（that）从句

在这一结构中，time 前面常用序数词来修饰，that 引导的是定语从句，从句中常用现在完成时态或过去完成时态，表示“这是 2.It + was + 时间点 + when clause(从句谓语用一般过去时)will be+时间点+when clause(从句谓语用一般现在时表将来)

例1：It was already evening when he came back.当他回家时已经8点了。

例2：It will be midday when they get home.当他们到家时将是中午。

3.It + will(not)be + 时间段 + before + 现在时 was(not)+时间段+before+过去时

例1：It will be another year before he comes here.例2：It was some time ______we realized the truth.(2005山东24)A.when

B.until

C.since

D.before

例2：正确答案：D。过了一段时间后我们才了解了真相。该句型中before前常用时间段，表示“„之后才„”“在„之前就„”;有时before前也可以用时间点，此时突出表示动作的变化。试比较：

例3：It was evening before we reached the little town of Tailstocks.当我们到达Tailstocks时已经黑了。(到达前天还没有黑)4.It/This is + the + 序数词 + 时间 + 定语从句(从句用完成时)

例1：It is the first time(that)I have been here.(定语从句)该句型可扩展为：It was+序数词+时间+定语从句(从句用过去完成时)

例2：It was the second time he had been out with her alone.例3：It’s the second time you________late this week.A.arrive

B.arrived

C.have arrived

D.had arrived 正确答案：C。这是这个星期你 《动手练一练》： 1.It was not until 1936________basketball became a regular part of the Olympic Games.A.that

2正确答案：B)

历年高考单选题

例1： I’m sorry you’ve been waiting so long, but it’ll still be some time ____ Brian get back.A.before B.since C.till D.after

例2：-Did Jack come back early last night？-Yes.It was not yet eight o’clock ________he arrived home.A.before

B.when

C.that

D.until

这类考题出现频率较高，考生又极易混淆，在复习中做出归类非常必要： 1.It is/has been + 时间段 + since + 一般过去时

如：It is/has been 5 years since he came to our school.这一句型可引申为：It was+时间段+since(从句用过去完成时)如：It was 10 years since he had arrived in

China.需要注意的是since从句的谓语动词一般是非延续性动词，但有时也可用延续性动词或表示状态的词，此时需要注意句子的翻译： 如：It is three years since she came to our class.她来我们班已经有三年了。It is three years since she was in our class.她离开我们班已经有三年了。

总之，在翻译此类句子的时候我们要记住一点，那就是“自从这一动作结束以来”，只要记住这一点我们就比较好理解句子了。

2.It + was + 时间点 + when clause(从句谓语用一般过去时)It will be+时间点+when clause(从句谓语用一般现在时表将来)如：It was already eight o'clock when he came back.当他回家时已经8点了。It will be midday when they get home.当他们到家时将是中午。

3.It + will(not)be + 时间段 + before + 现在时 It was(not)+时间段+before+过去时 如：It will be another year before he comes here.It was some time ______we realized the truth.(05山东24)A.when

B.until

C.since

D.before 正确答案：D。过了一段时间后我们才了解了真相。

4.It/This is + the + 序数词 + 时间 + that从句(从句用完成时)如：It is the first time that I have been here.该句型可引申为：It was+序数词+时间+that从句(从句用过去完成时)如：It was the second time that he had been out with her alone.5.It is +(high)time + that + did(虚拟语气)如：It is(high)time(that)we stopped pollution.其中that引导得从句中也可用should+V(原型)如：It is(high)time(that)you came/should come here.写作中表示建议时也常可用这类句型。如：It‘s high time we broke away from the bad habits and formed good ones.注意应将以上5种句型与强调时间的强调句型的区别：

6.It be + 时间(被强调部分)+ that 如：It was at 6 o’clock that we heard the noise.（强调句）It was 3 years ago that he joined the army.（非强调句）最简单的判断方法是：当表示时间的词前有介词或者后有副词时，一定是强调结构，必用that。试比较下面句式与强调句的不同之处： It was already ten o‘clock when he arrived.It is ten years since I met you last.It was quite some time before he found the elephant at all.以上几句中时间前无介词后没副词故不是强调句型。

探究语法填空中“It be +时间+conj”句型

在各类考试和历届高考试题中“it+be+time+conj”句型以不同的形式出现,往往使同学们顾此失彼,一头雾水,原因在于没有搞清楚各个句型的特点及实质,现结合历届高考题分别予以探究。

(一)It is +时间段+since+从句

It has been +时间段+since+从句 此句型的要点：

(1)注意since前后句子时态.since前的时态为is或has been,后的时态为一般过去时

Eg: It is(has been)ten years since I joined the army 译为:我参军已经十年了.(2)since后的动词若为延续性或状态性动词,应译为否定或相反,若为短暂性动词按字面意思翻译.Eg: It is(has been)ten years since I was a teacher =It is(has been)ten years since I left the army 译为:我复员十年了.It is ten years since I smoked =It is ten years since I stopped smoking 译为:我戒烟十年了.练习:

1、－What was the party like？－Wonderful.It’s years____ I enjoyed myself so much A: after B:before C:when D:since

2、I live in Beijing now, that’s to say, it’s ten years since I ____Beijing.A:lived in B:left for C:left D:was in

3、I’m a teacher now, that’s to say, it is ten years since I___ a teacher.A: have been B: was C:became D:turned Key.【Keys：

1、D

2、B

3、C】

（二）It will be +时间段+before+一般现在时的从句 “要过多久/ 不久„才„”

It was +时间段+before+一般过去时的从句 “过了多久才„” “before”句型和“since”句型的共性都加时间段,差异在于前后的时态和翻译。

Eg: ① It will be ten years before I return home.译为:要过十年我才能回家.② It was ten years before he found his lost boy.译为:过了十年他才找到了他失踪的儿子.练习:

1、It is reported that it may be two or three months_____it is possible to test this medicine on animals.A:since B:after C:before D:when

2、－How long do you think it will be ______ China sends a manned spaceship to the moon？

－Perhaps two or three years A:when B:until C:that D:before

3、How long do you think ____ the computer company brings out a new product？(2005.上海)

A: it will be before B:will it be until C:will it be when D: it will be that 【Keys:

1、C

2、D

3、A】

（三）It will be+时间点+when+一般现在时的从句

It was +时间点+when+一般过去时的从句 与“before”句型比较:前后时态一致

与“since”、“before”句型强调的是时间段，而”when“句型强调的是时间点。Eg: ① It will be midnight when I return home.译为:我回到家的时间将是午夜.② It was noon when the accident happened 译为:事故发生时已是正午.练习:

1、___ was 1979 ____ I graduated from university(1997.上海)A:That;that B:It;that C:That;when D:It;when

2、It was breakfast _____ our teacher punished me(2004.北京)A:when B: until C:since D: before 【Keys:

1、D

2、A】

(四)It is(was)+时间点+that的强调句型 强调句仅是形似，与“when”句型的比较很明显： 1.强调句时间点部分通常带有介词；

2.去掉it is(was)„„that之后，句子整合成一个完整的句子。Eg:①It was in the morning that I was robbed in the street.（删除后还原：I was robbed in the street in the morning.）=It was this morning that I was robbed in the street.②It was at 7:00 that I met Tom this morning.（删除后还原：I met Tom this morning at 7:00.）

=It was 7:00 when I met Tom this morning

第二篇：德语时间从句总结

德语时间从句总结

1.wenn, als

当„„的时候

wenn 可用于各种时态，表示多次性、重复性的行为。

如果从句位于主句前，常可在从句前加上jedesmal和immer表示强调。

jedesmal wenn, immer wenn 可以用sooft 代替。

als 只用语过去时，表示一次性的行为。

【Übungen】

请把下面句子变成以wenn或als引导的时间从句。

1.Ich war im vorigen Sommer in Wien.Ich besuchte meine Freunde.2.Der Junge war sechs Jahre alt.Da starben seine Eltern.3.Ich hatte in den Semesterferien Zeit.Ich ging immer Geld verdienen.4.Man senkte den Vorhang.Ich verließ das Theater.2． während, solange

以während引导的时间从句表示主句的动作在从句的动作进行过程中发生，回答wann提出的问题；主句与从句的时态一般一致；从句可位于主句之前，也可位于主句之后。

während, solange 都表示两个或多个同时发生的行为。主从句时态一般一致。

z.B.Während ich arbeite, höre ich Musik.solange: 表示主从句动作同时开始，同时结束。

z.B.Solange er studierte, wer sie berufstätig.Solange sie hier bleibt, warte ich auf sie.3． bevor, ehe

bevor意为“在„„之前”, 由其引导的复合句，主句的动作发生在从句之前。一情况下主从句用一样的时态。在意义相同时可以用ehe代替bevor.4． nachdem

nachdem意为“在„„之后”, 主句的动作发生在从句之后。如果主句的时态为现在时或将来时，从句即为现在完成时；主句的时态为过去时或现在完成时，从句即为过去完成时。

5． seitdem, seit

seitdem和seit意为“从„„以来”，由其引导的时间从句表示主句的动作自某一时刻开始，延续到讲话人说话时为止，回答seit wann提出的问题；主句和从句可用相同或不同时态；从句一般前置。

对于seit引导的从句来说，如果发生在过去的行为是一次性的，只是他的有效力持续到现在，则主从句中的时态不一致。

z.B.Seit man das Verkehrsschuld hier aufgestellt hat, passieren weniger Unfälle.6． sobald

一旦，一......就......主句行为紧接着从句行为而发生，有时用sowie, kaum dass 代替

Sobald Heinrich die Prüfung gemacht hat, beginnt er seine Arbeit.Sobald die Gäste in den Saal kommen, beginnt das Konzert.7． bis

bis意为“到„„时为止”，它引出的时间从句表示主句的动作延续到从句动作发生时为止，回答bis wann提出的问题；主句和从句可用相同或不同的时态。

第三篇：初中英语知识点总结：时间状语从句

在复合句中，由时间连接词引导的状语从句叫做时间状语从句。时间状语从句通常由when, while, as，after,before,since,until等词引导。

一、时间状语从句种类

1、引导的从句表示主从句的动作同时发生，或从句的动作在主句之前。when引导的从句的谓语动词可以是延续性的动词，又可以是瞬时动词。例如：

When she came in, I stopped eating.她进来时，我停止吃饭。(瞬时动词)

When I lived in the countryside, I used to carry some water for him.当我住在农村时，我常常为他担水。（延续性的动词）

We were about to leave when he came in.我们就要离开，就在那时他进来了。

2、While引导的从句的谓语动作必须是延续性的，并强调主句和从句的动作同时发生（或者相对应）。并且while有时还可以表示对比。例如：

While my wife was reading the newspaper, I was watching TV.(was reading是延续性的动词，was reading和was watching同时发生)

I like playing football while you like playing basketball.我喜欢踢足球，而你喜欢打篮球。（对比）

3、As表示“一边……一边”，as引导的动作是延续性的动作，一般用于主句和从句动作同时发生；as也可以强调“一先一后。例如：

We always sing as we walk.我们总是边走边唱。（as表示“一边……一边”）

As we was going out, it began to snow.当我们出门时，开始下雪了。（as强调句中两个动作紧接着先后发生，而不强调开始下雪的特定时间）

4、由before和after引导的时间状语从句，表示两个动作一前一后发生。例如：It will be four days before they come back.他们要过四天才能回来。

After you think it over, please let me know what you decide.你仔细考虑过以后，告诉我你是怎样决定的。

5、由till或until引导的时间状语从句。till和until一般情况下两者可以互换，但是在强调句型中多用until。并且要注意的是：如果主句中的谓语动词是瞬时动词时，必须用否定形式；如果主句中的谓语动词是延续性动词时，用肯定或否定形式都可以，但表达的意思不同。till不可以用在句首，而until可以放在句首。例如：

I didn't go to bed until（till）my father came back.直到我父亲回来我才上床睡觉。

I worked until he came back.我工作到他回来为止。

6、由since引导的时间状语从句表示“自从……以来”。

I have been in Beijing since you left.自从你离开以来，我一直在北京了。

7、由as soon as引导的时间状语从句表示“一……就”。例如：

As soon as I reach Canada, I will ring you up.我一到加拿大，就给你来电话。

二、时态问题

在状语从句中，有“主将从现”的规定，即主句用一般将来时，从句用一般现在时表示将来时。例句： I will call you as soon as I arrive in Beijing.我到北京就将给你打电话。（这是由as soon as引导的时间状语从句，从句中的谓语动词arrive是一般现在时，表示一般将来时，决不可用will arrive）常见考法

对于时间状语从句的考查，多以单选和完形填空的形式，从连词的意义角度让大家选择连词，或从时态的角度设题，考查学生灵活运用的能力。典型例题：I'm sure he will jump up when he the good news.A.know B will know C.knows D knowing 解析：本题考查学生时间状语从句的时态问题。时间状语从句中，主句若是一般将来时，从句应用一般现在时表示将来时。从句的主语是单三人称，所以排除 A。

答案： C 误区提醒

When既可以引导时间状语从句，也可以引导宾语从句，辨别它在这两种从句中的时态是我们经常容易出错的地方。

典型例题：I don’t know when he next week.when he , please let me know.A.comes, comes B.will come, will come C.will come, comes D.comes, will come 解析：第一句话“我不知道他下周什么时候来”，when引导宾语从句，表示将来时，就用一般将来时will come；第二句话“当他来的时候，请让我知道”，when引导时间状语从句，用一般现在时表示将来时，所以用 comes。答案： C
