时间状语从句(全面掌握)
状语从句
思考：什么是从句？
I don’t know the girl in red.
I don’t know the girl who is playing under the tree.
从句要素：①至少要有两个句子
②要有引导词
一、什么是状语从句
状语的功用：状语说明地点、时间、原因、目的、结果、条件、方向、程度、方式和伴随状况等。
状语一般由副词、介词短语、分词和分词短语、不定式或相当于副词的词或短语来担当。其位置一般放在句末，但也可放在句首或句中。
I didn’t realize how special my mother was until I became an adult.
You should have put the book where you found it.
I didn’t go because I was afraid.

2.引导词具体讲解：
当…时候：It was six o’clock when I got home.

1)when 这时Sb was about to do sth/was on the point of doing sth when…
Sb had just done sth when…
既然: It was foolish of you to take
a taxi
3

could walk
there in
five
minutes.
既然你能5分钟就走到那儿，再搭出租车真是太傻了。
当…时候(引导持续性动作): He fell asleep while he was reading a book.
2) while 然而(用于句中) : He likes pop music while I am fond of folk music.

last two months.
肯定句:主句的谓语动词必须是延续性动
词。He 6
worked until
late into the
night.
4)till, until
否定句：主句的谓语动词是非延续性动词。
★not…until 的倒装句式和强调句式
He didn’t consider having a holiday until he retired from teaching three years ago.
倒装句式：Not until he retired from teaching three years ago did he consider
having a holiday.
强调句式：It was not until he retired from teaching three years ago that he
considered having a holiday.
5) before 在…之前,….才We had sailed four days before we saw land.
还没来得及Before I could get in a word, he had measured me.
★It was +时间段+before sb did sth…(…才)
★It will be+时间段+before sb does sth (…才)
It was two weeks before we met again.两周之后我们才见面。
It will be two weeks before we meet again. 我们再过两个周才能见面。
6) since 自从… She has been working in this factory since she left school.
既然Since Babara is no longer my wife, I’m no longer responsible for
7
her debts. 既然芭芭拉不再是我的妻子，我
也不用再负责她的债务了。
★It is/ has been +段时间+ since sb did sth…（自从…以来多长时间）
7) 关于一…就…的表达方式：as soon as, immediately, directly, instantly, the moment, the minute, the instant, no sooner…than…, hardly/scarcely…when, once 一…就…

8)每次…；每当…;下次…等表达方式：every time, each time, next time, the last time, any time, all the time 等名词短语用来引导时间状语从句。
Every time I was in trouble, he would come to help me out.
9) 几个极易混淆的时间状语从句：
1）It was +时间点+when…（当….的时候时间是….）It was 5 am when we arrived at the village.
2）It was/will be+时间段+before…(没过…就／过了…才) It was/will be two weeks before we met/meet again.
3）It is /has been +时间段+since…（自从…以来有…）It is/has been 3 years since we last met.
★突破点：一看be动词的时态，二看时间段还是时间点。

3.时间状语从句和强调句的区别
强调句的句型是：It is (was) 被强调部分+ that (who) + 句子其他部分
It was seven o'clock when we reached the station.（状语从句）
=It was "at" seven o'clock "that" we reached the station.(强调句，定语从句）
强调句和时间状语从句的区别是：时间状语从句可以去掉，不影响句子的完整性。而强调句that/who引导的句子是不能去掉的，否则句子就不完整了，单独的“It was at seven o'clock”是错误的。
(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或后面有副词；
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.
9
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
4.关于时间定语从句和时间状语从句的区别
时间状语从句和定语从句的区别其实跟上面说的是一样的，强调句型其实就是一种特殊的定语从句。
本身最简单的表达法是：We reached the station at seven o'clock.
强调句It was "at seven o'clock" that we reached the station（为了强调"at seven o'clock"）
同时它也是定语从句：从句“that we reached the station”修饰的是it=the time.
也就是说关键是看前面有没有先行词，有就是定语从句，没有就是时间状语从句。
如：1.By the time when you arrived in Beijing, we had stayed there for two weeks.
有先行词the time 那么when you arrived in London就是定语从句
2.when you arrived in Beijing, we had stayed 10
there for two weeks.
没有先行词when you arrived in London就是时间状语从句。
5.“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 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。
2. It was two months before he designed the
11
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
12
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
13
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“这是第……次做某事”。例如：
1. This is the first time in my life that I have come to Beijing.
这是我一生中第一次来北京。
2. It was the third time that he had asked the same question. 这是他第三次问同一个问题。
14
七、It is （high ）time +that 从句
在这一结构中，that 从句中的谓语动词常用虚拟语气，即“should + 动词原形”或用动词的过去式，表示“该做某事了”。例如：
1. It is high time that we began our work. 我们该开始我们的工作了。
2.It is time that he left the place. 他该离开那个地方了。
总结二
例1：It is almost five years_____we saw each other last time.(05北京)
A.before
B.since
C.after
D.when
例1.正确答案：B我们已经有5年没见面了。
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
例2.正确答案：B他回家时还不到8点
15
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
例1：It is/has been10years since he came here.这类句型可转化为：=Ten years has passed since he came here. 这一句型可扩展为：It was+时间段+since(从句用过去完成时)
例2：It was years since he had arrived in China.(过去是+since+过去完成时) 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：
例3：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。
2.It+was+时间点+when 16
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：
17
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.havearrived D.hadarrived 正确答案：C。这是这个星期你第二次迟到了。
5.It is+(high)time+that+did(虚拟语气)
例1：It is(high)time(that)we stopped pollution. 其中that引导得从句中也18
可用should+V(原型)
例2：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。
例3：It‘s high time we took measures to solve this problem.
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
例1：It was at6o’clock that we heard the noise.
例2：It was3years ago that he joined the army. 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
19
强调句型。

When I came home my wife was cooking dinner. 我回家时，妻子在做晚饭。 如果when引导的时间状语从句的主语与主句主语相同，而从句的谓语又是be动词时，那么从句中的主语和be 可以省略;当when引导的时间状语从句的主语与主句主语相同时，往往还可以用“when+分词”的形式替代该状语从句。例如： When (you are) in trouble, ask her for help. 当你遭遇麻烦的时候去向她求助。 When I came into the room (=When coming into the room), I found him lying there asleep. 当我进入房间的时候，我发现他躺在那儿睡着了。 (2) while引导时间状语从句时表示“当……的时候”，它强调主句的动作与从句的动作同时持续地进行，用于这一用法时while引导的时间状语从句和主句中的谓语动词必须是延续性动词，或者主句的动作发生在从句动作的进行过程中，主句中的谓语动词通常是非延续性动词，例如 Study while you study; play while you play.
