时间状语从句讲解和练习(答案)

时间状语从句

用句子表达一件事情或一个行为发生的时间，这个句子就叫时间状语从句。时间状语从句根据其所表示的时间不同，所使用的连词也不同。下面我们一起来看一下几个常见的时间状语从句：

1．when引导的从句：表示主句的动作和从句的动作同时发生，或从句的动作发生在主句动作之前。

例如：I was going out when a visitor came. (动词动作同时发生。)我正要出门，有客人来访。

I shall tell her the good news when she comes.她来时，我将告诉她这个好消息。

小试牛刀：I found mother cooking for me. I got home.(when)_______________________________________ He was listening to the radio when I home. (get)

2．while 引导的从句：表示“当……过程中”，强调某一段时间内主句和从句中谓语动词所表示的动作在同一时期发生。由于while从句表示一个持续的行为，所以从句中要用持续性动词，并且持续性动词常用进行时态。例如：Keep an eye on my little sister while I am away.我不在时，请照看一下我的小妹妹。

While we were watching TV, Jim came in. 我们看电视的时候，Jim进来了。

小试牛刀：It started to rain. We were playing football.(while)_______________________________________ Lucy was cleaning the room Lily was listening to music.

3．as引导的时间状语从句：表示“当……的时候；一边……一边……；随着……”，其从句的主语与主句的主语往往是同一人或物。

例如：She sang as she worked. 她一边工作一边唱歌。=She was singing as she was working.

I saw him as he was getting off the bus. 正当他下公共汽车时, 我看见了他。

小试牛刀：we walked, we talked.

You will grow wiser you grow older.

4．before引导的从句：一般表示主句的动作发生在从句动作之前。

例如：I didn’t know any English before I came here. 我到这儿来之前，一点英语都不懂。

例如：I had written my report before my father came back.

小试牛刀：He bought the ticket he went to see the film.

5．after引导的从句：表示主句的动作发生在从句动作之后。

例如：After he locked the door, he left. 他锁上门后，就走了。

After he had finished his work, he played a game of chess with his friend. 他做完工作后，和朋友下了一盘棋。小试牛刀：I will go out to play basketball with you. I finish my homework.(after)

_______________________ _

He left the classroom he had finished his homework the other day.

6．since引导的从句：表示“自从……以来”，从句中的动词一般表示动作的起点，用过去时。主句中的动词表示动作延续的情况，一般用现在完成时。如果主句中的动词表示的不是延续的动作而是表示目前的状态，可用一般现在时。

例如：Since he met this good friend, he has made great progress in his studies.

自从遇见了这个好朋友，他已在学习上取得了巨大的进步。

例如：It is twenty years since she joined the Party. 她入党二十年了。（主句中的动词表示的是状态，用现在时。）小试牛刀：it is five years since we last time.（meet）

Mr green has taught in that school since he (come) to China three years ago.

7．until 引导的从句：表示一个动作持续到某一时刻。

（1）表示“直到……”，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。（2）表示“直到……才”，主句用否定式，从句用肯定。如果主句中的谓语动词是瞬间动词时，必须用否定形式。

例如：They worked until it was late. 他们一直工作到天黑。

She didn’t go to bed until she finished her homework. 她写完作业才睡觉。

小试牛刀：All the people left. He waited.(until)________________________________________ He went to bed . his father came home.________________________________________

8．as soon as 引导的从句表示“一……就”，强调动作紧密相连。

例如：As soon as she came to the classroom, she began to read English.她一到教室，就开始读英语。

小试牛刀：We start to sing. It''s 12 o''clock. (as soon as)________________________________________

9. by the time 到。。。为止(所在句子的主句应用完成时)

例如：By the time he gets there , his father has already gone.他到家的时候，他爸爸已经走了。

小试牛刀：By the time I got to school, the class .（begin）我到校时，已经开始上课了。

知识扩展

1. it is +时间段+since+一般过去时（从。。。以来多长时间了）

例如：it is five years since we met last time.从我们上次见面已经五年了。

2. it is/ will be +时间段+before+一般现在时，it was+时间段+before+一般过去时(。。。才)

例如：it is a long time before I go to sleep .过了很长时间我才睡着。

it was an hour before the police arrived.过了一个小时，警察才来。

小试牛刀：It_____(be) ten years since we ________(leave) that city .

It is reported that it may be two or three months_____it is possible to test this medicine on animals

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

4、巧记10个瞬间性动词

在学习以when和while引导的时间状语从句时，用到了瞬间动词和延续动词。常见的瞬间动词有

die(死)，come(来)，go(去)，eave(离开)，arrive(到达)，begin(开始)，buy(买)，,join(加入)，borrow(借进，借出)，return(归还)等。

这10个瞬间动词可用两句口诀来帮助记忆: 开始离去,借来还, 出生入死,买到家。

注释:

1."开始离去,借来还"为begin,leave,go,borrow,come,return六词；

2."出生入死,买到家"为join,die,buy,arrive四词。

3.各词改为相应的延续动词为：

begin→be on, leave→be away from, borrow→keep, go→be, come→be here, return→be back,

join→be in, die→be dead, buy→have, arrive→be here等。'

5、状语从句与主句的时态问题

1.由when、while引导的时间状语从句的时态：（主过从过）

主句（过去进行时）+when +从句（一般过去）

主句（一般过去时）+when +从句（过去进行时）

主句（一般过去时）+while +从句（过去进行时）

主句（过去进行时）+while +从句（过去进行时）

注意：看动词为短暂性动词用一般过去时，动词为延续性动词则用过去进行时。

小试牛刀：Mother （cook）supper when I (get) home yesterday.

Last Sunday I (meet) Lin Hong when I (walk) in the street.

When the students (have ) a meeting, the teacher (come) in.

While Han Meimei (sweep) the floor, Lucy (carry) water.

2. 由when、after、before、by the time引导的时间状语从句的时态：

主句、从句的谓语动词都已完成，则先发生的动作用过去完成时，后发生的动作用一般过去时。

例如：After he had finished his work, he played a game of chess with his friend.

小试牛刀：When they (get) to the cinema last light, the film (start).

I (go) out with my friends after I (finish) all the homework last night.

3.时间状语从句与主句的时态不一致。（主将从现：主句用将来时，而时间状语从句用一般现在时）

小试牛刀：As soon as I reach Canada, I you up. (ring)

I will call you as soon as I the result. (know)

比较状语从句讲解和练习题

比较状语从句： 状语从句指句子用作状语时，起副词作用的句子。比较状语从句是其中的一种，主要运用于形容词和副词的原级、比较级及最高级的句子之中。原级：as…as （和……一样），not so（as）…as …（和不一样）；比较级：more…than（更）；最高级：The most…in/of， the + 形容词+est…of/in。常用引导词：as（同级比较），than（不同程度的比较）；特殊引导词：the more … the more … ；just as …，so…；A is to B what /as X is to Y；no … more than；not A so much as B。 比较状语从句通常由as或than引起，这类从句和大多数状语从句不同，它们不修饰动词，而是修饰as，so，less，more等副词，或其他比较级的词，如taller， harder．在这里讨论它们，不是作为动词修饰语，而是作为一种状语从句。包含这类从句的句子通常为L，即从句在后：She is as tall as I（or me）． He works as hard as his brother（does）． He does not work as hard as his brother． He does not work so hard as his brother． No other men work as（or so） hard as his brother （does）．No other men work as hard as does his brother． She is taller than I（or me）． She is taller this year than（she was tall）last year． She is more shy than unsocial． She thinks more about her appearance than（she thinks about）her personality． She finds it easier to read than to write． She is not taller than I．（Both are tall．） She is no taller than I．（Both are short．）注意这两句话的区别。 I cannot persuade him any more than your persuade a pillar．（= I am unable to persuade him，just as you are unable to persuade a pillar．） I can forget her no more than she（forgets）me． Nothing is more dangerous than that you （should）make friends with him． I will help you rather than that you（should）have any trouble．rather than 而不是…

状语从句讲解及练习

状语从句 在复合句中担任状语成分的从句称为状语从句，修饰主句的谓语动词，形容词或副词，状语 说白了就是修饰动作的词或句，也可以理解成修饰谓语的词或句。通常由副词、介词短语、 动词不定式、分词和从句等担当。例如： 1. Naturally, our grandparents were pleased to get our phone call. (副词 ) 2. We worked hard, from sunrise to sunset. (介词状短语 ) 3. To help my disabled aunt, I spend an hour working in her house every day. (不定式 ) 4. Seen from a distance, the farmhouse looked deserted. (过去分词 ) 5. I know how to light a camp fire because I had done it before .（原因状语从句） 状语的位置比较灵活，可以位于句首、句末或句中。enough 用作状语修饰形容词和副词时 必须后置。 状语从句主要用来修饰主句或主句的谓语。一般可分为九大类，分别表示时间、地点、原因、目的、结果、条件、让步、比较和方式。尽管种类较多，但由于状语从句与汉语结构和用法 相似，所以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词 和特殊的连接词即考点。现分别列举如下: 1．时间状语从句 常用引导词： when, as, while, as soon as, while, before, after, since , till, until 特殊引导词： the minute, the moment, the second, every time, the day ， the instant, immediately , directly, no sooner ? than, hardly ? when, scarcely ? when I didn ’ t realize how special my mother was until I became an adult. While John was watching TV , his wife was cooking. The children ran away from the orchard( 果园 ) the moment they saw the guard. No sooner had I arrived home than it began to rain. Every time I listen to your advice, I get into trouble. When , while, as 都可解释为“当```的时候”但侧重点有所不同。 1) When Eg: When I arrived home , I had a little rest. 注意点： when 从句的主语与主句主语相同，谓语动词是be 动词时，从句主语和be 可以省略。Eg: When (she was) walking along the street, she met her class teacher. 2) As As 除了表示“当```的时候”，还可表示为“一面``` 一面”，“随着” Eg: He sang as he danced.(一面 ```一面 ) You will grow wiser as you grow older.(随着) 3) While 表示“当 ``` 的时候” 强调主句的动作和从句的动作同时发生，从句一般用进行时， 从句动词必须是延续性动词。 Eg: While we were working, they were having a rest. While (they were) having a discussion, they got very confused. 注意点： while 有对比的含义，解释为“然而”。 eg: I prefer black tee, while he likes coffee. 1．until, not ? until 表示“直到 ```才” ,在肯定句中主句常用延续性动词；在否定句中主句常用短暂性动词。

高考状语从句讲解

状语从句 一、时间状语从句 1、when, while, as 和whenever when 表时间点，时间段 while 表时间段；有“而”的意思 as “当……”,“一边……一边”，“随着……” whenever 每当，无论什么时候 It is cold when it snows. While there is life, there is hope.

As we age, we trade strength for ingenuity, speed for thoroughness, and passion for reason. 随着年龄的增长，我们用力量换来了机敏，以速度换来了严谨，以热情换来了理智。 注：1)when还可作并列连词，其意义为“那时，这时”，相当于and at this/that time。常用于下列句式： sb.was doing sth.when...某人正在干某事就在这时…… sb.was about to/ going to do sth.when...某人正打算干某事就在这时…… sb.body has just done sth.when...某人刚干了某事就在这时…… 2)如果主句表示的是短暂动作，而从句用延续性动词的进行时态表示在一段时间内正在进行的动作时，when，while 与as可互换使用。如： When/While/As I was walking down the street，I came across an old friend of mine. 2、before/ after It will be five years before we meet again.五年之后我们才能见面。 After you think it over, please let me know what you decide. After her husband had gone to work, she sent her children to school. 3、until, till, not...until 1)肯定句：主句的谓语是延续性动词，主从句均为肯定式，意为“某动作一直持续到某时间点才停止”

状语从句讲解及习题附答案

（一）状语从句概述 定义状语从句用作状语，是起副词作用的句子。 位置状语从句可以放在主句之前，也可以放在主句之后，时间、条件、原因和让步状语从句放在句首时需要用 逗号和主句隔开。 分类根据其作用可以分为时间、地点、原因、条件、目的、让步、方式和比较等状语从句。 作用它可以修饰谓语、非谓语动词、定语、状语和整个句子。 （二）状语从句详解 1. 时间状语从句 引导词用法示例 when 意为“当…的时候”。When 引导从句的谓语动词可以 是延续性动词，也可以是 瞬间动词。并且when有 时表示“就在那时”A liar is not believed when he speaks the truth.说谎者讲真话时也没有人相信。When he arrives, I’ll call you. When you laugh and smile, your body relaxes. while 意为“在…的时候，在…的 同时”。While引导从句的 谓语动词必须是延续性While I was standing at the window, I saw several boys running along the street.

的，发生时间较长，并强调主句和从句的动作同时发生（或者相对应）。While 有时还可以表示对比。While John was watching TV, his wife was cooking. as 意为“一边…一边…”。As 引导的动作是延续性的， 发生时间较短，一般用于 主句和从句动作同时发 生；as也可以强调一前一 后。The writer was angry as he was travelling on a train to London because someone had invaded his “space”. He smiled as he stood up. after 意为“在…之后”。表示主句 动作发生在从句动作之 后。主句与从句的动作时 间关系与before引导的从 句相反。With many hungry visitors waiting, don’t stay too long at your table after you have finished. If an early exit is necessary, you can leave after a scene is over. before 意为“在…之前”。引导的从 句不用否定形式的谓语， 并且当before引导的从句 位于主句之后，有时译成 “就，才”。当主句用将来时，You can’t watch TV before you finish your homework. Before it ended, the theatre was almost empty. My father had left for Canada

第章状语从句 学习指导 状语从句在句子中作状语，用来修饰主句或主句的谓语。一般可分为九大类,分别表示时间、地点、原因、目的、结果、条件、让步、比 较和方式。尽管种类较多,但由于状语从句与汉语结构和用法相似,所 以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词。现分别列举如下: 状语从句分九类： 在这一章节的学习中，要求同学们掌握各类状语从句基本概念，并能够灵活应用。 第一节时间状语从句 时间状语从句用一般现在时表示将来。连接时间状语从句的连接词有：2．when，while，as均可表示“当……的时候”。 when强调“特定时间”，表示主句谓语动词的动作与从句谓语动词的动作是同时发生的，或从句的动作发生在主句的动作之前；while表 示的时间是一段，而不是一点，as多用在口语中，强调“同一时间”或“一前一后”，有时还有“随着”的含义。 When spring came, he felt like a trip.春天来了，他想去旅游。 As spring warms the good earth，all flowers begin to bloom．(as有“随着”的含义) as, when, while都表示主、从句的动作或状态同时发生，但三者也有

区别。as和when引导的从句既可表示一点时间，也可表示一段时间，从句中的谓语动词既可以是持续性动词，也可以为短暂性动词，经常可以互换使用；while引导的从句通常表示一段时间，从句中宜用持续性动词作谓语。当从句中的谓语动词为持续性动词时，这三者可以通用（前面例句中已有体现），再如： 1 / 18 Mother was worried because little Alice was ill, especially as / when / while father was away in France.妈妈担心，因为小艾丽思病了，特别是当父亲远在法国的时候。 如果从句和主句要表示一个人的两个动作交替进行或同时完成时，则多用as，可译为“一边......，一边......”。例如： He looked behind from to time as he went.他一边走，一边不时地往后看。 As time goes on, it's getting warmer and warmer..随着时间的推移，天气变得越来越暖了。 I thought of it just as you opened your mouth.你一张嘴我就知道你要 说什么。（若表示两个短促动作几乎同时发生时，用as的场合多于when.） 当主从句之间表示转折或对比关系时，多用while, 不用as或when。如：

时间状语从句讲解和练习(答案)

时间状语从句 用句子表达一件事情或一个行为发生的时间，这个句子就叫时间状语从句。时间状语从句根据其所表示的时间不同，所使用的连词也不同。下面我们一起来看一下几个常见的时间状语从句： 1．when引导的从句：表示主句的动作和从句的动作同时发生，或从句的动作发生在主句动作之前。 例如：I was going out when a visitor came. (动词动作同时发生。)我正要出门，有客人来访。 I shall tell her the good news when she comes.她来时，我将告诉她这个好消息。 小试牛刀：I found mother cooking for me. I got home.(when)_______________________________________ He was listening to the radio when I home. (get) 2．while 引导的从句：表示“当……过程中”，强调某一段时间内主句和从句中谓语动词所表示的动作在同一时期发生。由于while从句表示一个持续的行为，所以从句中要用持续性动词，并且持续性动词常用进行时态。例如：Keep an eye on my little sister while I am away.我不在时，请照看一下我的小妹妹。 While we were watching TV, Jim came in. 我们看电视的时候，Jim进来了。 小试牛刀：It started to rain. We were playing football.(while)_______________________________________ Lucy was cleaning the room Lily was listening to music. 3．as引导的时间状语从句：表示“当……的时候；一边……一边……；随着……”，其从句的主语与主句的主语往往是同一人或物。 例如：She sang as she worked. 她一边工作一边唱歌。=She was singing as she was working. I saw him as he was getting off the bus. 正当他下公共汽车时, 我看见了他。 小试牛刀：we walked, we talked. You will grow wiser you grow older. 4．before引导的从句：一般表示主句的动作发生在从句动作之前。 例如：I didn’t know any English before I came here. 我到这儿来之前，一点英语都不懂。 例如：I had written my report before my father came back. 小试牛刀：He bought the ticket he went to see the film. 5．after引导的从句：表示主句的动作发生在从句动作之后。 例如：After he locked the door, he left. 他锁上门后，就走了。 After he had finished his work, he played a game of chess with his friend. 他做完工作后，和朋友下了一盘棋。小试牛刀：I will go out to play basketball with you. I finish my homework.(after) _______________________ _ He left the classroom he had finished his homework the other day. 6．since引导的从句：表示“自从……以来”，从句中的动词一般表示动作的起点，用过去时。主句中的动词表示动作延续的情况，一般用现在完成时。如果主句中的动词表示的不是延续的动作而是表示目前的状态，可用一般现在时。 例如：Since he met this good friend, he has made great progress in his studies. 自从遇见了这个好朋友，他已在学习上取得了巨大的进步。 例如：It is twenty years since she joined the Party. 她入党二十年了。（主句中的动词表示的是状态，用现在时。）小试牛刀：it is five years since we last time.（meet） Mr green has taught in that school since he (come) to China three years ago. 7．until 引导的从句：表示一个动作持续到某一时刻。 （1）表示“直到……”，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。（2）表示“直到……才”，主句用否定式，从句用肯定。如果主句中的谓语动词是瞬间动词时，必须用否定形式。
