高中英语状语从句讲解及练习含答案

状语从句

状语从句在句中作状语，可分为：时间、条件、让步、原因、目的、结果、比较、地点、方式状语从句。

一、时间状语从句

引导时间状语从句的连词有：when, as, while, until, not…until, before, after, since, the minute, the moment, each( every, next, the first) time等。时间状语从句中一般用一般现在时或一般过去时。

1．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.

2．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。

肯定句：I waited until midnight.

否定句：I did not leave until midnight.

注意点：

1）not until…在句首，主句用倒装

eg: Not until you had explained how did I manage to do it.

2) It is not until…that…引导的强调句

It was not until it was dark that he came back.

3. the minute, the moment, each time都可表示“一```就```”

eg: The worker recognized the type of the machine the moment he saw it.

注意点：

the minute, the moment, each ( every, next, the first) time作连词不和when 连用。4．Hardly/scarcely…when, no sooner…than, as soon as表示为“一```就```”

eg: I had hardly/scarcely got home when it began to rain.

I had no sooner got home than it began to rain.

It began to rain as soon as I got home.

注意点：Hardly/scarcely…when, no sooner…than位于句首，主句用倒装

eg: Had I hardly/scarcely got home when it began to rain.

No sooner had I got home than it began to rain.

二条件状语从句

条件状语从句分为两大类：真实条件句和虚拟条件句。引导条件状语从句的连词有：if, even if/though, unless/ if …not, as long as/ so long as, as far as/so far as, provided/providing (that), on condition that 等。条件状语从句中如果主句是将来时，条件状语从句用一般现在时。

1.u nless 和if…not

unless 相当于if…not

eg: You will fail unless you study hard.

You will not fail if you study hard.

注意点：

在虚拟条件句中可用if…not，但不能用unless

eg: If she were not too silly,she would understand.

2．引导条件状语从句的其它连词：

Eg: You may go there ,as long as you keep quite.

Eg: I shall give you the book on condition that you return it tomorrow.

Eg: I will go provided that you go too.

三让步状语从句

引导让步状语从句的连词有：though, although, even if/ though, however, no matter how, no matter what, no matter who等。

1．though, although不可与but连用，但可以和yet , still连用.

Eg: Though/Although it is raining ,they are still running outside.

注意点：

1）though可引导倒装(although不引导倒装)，结构为：

强调对象+as/though+主语+其它成分，强调对象可为表语（名词、形容词）或状语（副词），表语为名词时，前面不用冠词。

Child as/ though he was, he knew what was the right thing to do.

Tired as he is, he goes on with his work.

2）despite 和 in spite of 也有让步意义，后接名词或动词，而though, although是连词，后接从句。

Eg: Despite /In spite of wanting to see him again, she refused to reply to his letter. Though/although she wanted to see him again, she refused to reply to his letter.

2. “no matter+疑问词”或“疑问词+后缀ever”

eg: No matter what happened, he would not mind.

Whatever happened, he would not mind.

注意点：no matter+疑问词不能引导名词性从句

3.even if/ though表示“即使”

eg: He doesn’t want to marry her even if/ though he loves her very much.

四原因状语从句

引导原因状语从句的连词有：because, since, as , now that ,considering that, for the reason that , due to the fact that,owing to the fact that等

1．because

because语气最强，通常用于回答why 提出的问题

注意点：

在it was…that…的强调结构中，强调原因状语从句可用because引导，不用since,as, for 引导。

Eg: It is because she is too inexperienced that she does not know how to deal with the situation.

2. since和as

since的语气比because 弱，比as强，表示间接的，已知的原因，自然的结果，表示“既然，由于”。

Eg: As/ Since you are not very well, you had better have a rest.

3．for

当for表示原因关系时，for分句是对第一分句内容的推断或猜测。

Eg: It must have rained last night, for the ground is wet now.

五目的状语从句

引导目的状语从句的连词有： so that, in order that, lest, in case, for fear that 等。

Eg: You must speak louder so that/in order that you can be heard by all.

He wrote the name down for fear that he should forget it.

Better take more clothes in case the weather is cold.

注意点：lest, in case, for fear that所引导的状语从句中，动词可以用虚拟语气，形式为should+动词原形，也可不用虚拟语气，用动词的一般现在时或一般过去时。

Eg: You had better leave the key at home in case one of us should think of/thinks of coming back.

六结果状语从句

引导结果状语从句的连词有：so that, so…that, such…that等

eg: He is so young that he can not go to school.

He is such a young boy that he can not go to school.

1．常用句型：

so+形容词/副词+that从句

so+形容词+a/an+单数可数名词+that从句

such +a/an+形容词+单数可数名词+that从句

such +形容词+复数可数名词/不可数名词+that从句

2．so和such的搭配规律

such修饰名词或名词词组，so修饰形容词或副词,so还可接many, few, much, little等。Eg: so foolish such a fool

so nice a flower such a nice flower

so many/few flowers such nice flowers

so much/little money such rapid progress

so many people such a lot of people

七比较状语从句

引导比较状语从句的连词有：as…as, than, not so…as, the more…the more等

如：

He speaks English as fluently as his brother (does)

I can’t jump so /as high as he (does)

There are more workers in this factory than in the one next to it .

The more you read, the more interesting , you will find the novel is .

连接词than 可作为关系代词用。如：

He wrote more than was necessary

Don’t carry more m oney than is needed

八地点状语从句

引导地点状语从句的连词有:where, wherever以及 where构成的复合词等

eg: She found her calculator where she lost it.

Wherever I am, I will miss you.

注意点：

eg: I happened to see your dictionary lie where I used it last time.（地点状语从句）

I happened to see your dictionary lie in the lab where I used it last time.（定语从句）

九方式状语从句

引导方式状语从句的连接词有as, just as, as if / though（一般用虚拟语气，也有用直陈语气的）等。

EG：Just do as you are told.

The workers went on working as if nothing had happened.

He talked to the girl as though he had fallen in love with her.

在just as ---, so --- 结构中，as 带有比喻含义。意为“正如”，多用于正式文体。

EG：Just as some people like sports, so some people like music.

【答案与解析】

1. 选D。when 意为“在(当)……时候”。其余三项填入空格处，句意不通。

2. 选D。until 意为“直到”，句意为“一位优秀的故事讲述者必须能够让听众在故事结束前一直保持好奇心”。

3. 选C。as long as 意为“只要”，全句意为“只要我知道这钱是安全的，我就不会担心了”。类似地，下面一题也选as long as：

“What are you going to do this afternoon?’ “I’ll probably go for a walk later on ____ it stays fine.”

A. as far as

B. as long as

C. even if

D. as if

4. 选D。unless 意为“如果不”、“除非”，用以引导一个条件状语从句。

5. 选C。考查not…until… 句式，其意为“直到……才……”。

6. 选B。whatever 引导的是让步状语从句，相当于no matter what。注意不能选A，因为suggest 是及物动词，它应带自己的宾语，而however 不能用作宾语。

7. 选A。where 指“在……的地方”，用以引导地点状语从句。

8. 选A，wherever 意为“无论什么地方”。

9. 选B。根据语境可推知。如下面一题也选as soon as：

_______ he became rich he cast aside all his old friends who gave him some help.

A. While

B. As soon as

C. Suddenly

D. Then

10. 选A。whatever her faults 为让步状语从句，句末省略了谓语动词are。

11. 选A。now that 为连词，用以引导原因状语从句，其意为“既然”，与since 同义。其中的might as well意为“不妨”。全句意为“既然你得到一个机会，你不妨充分利用它”。

12. 选C。the first time 在此用作连词，用以引导状语从句。句意为“我第一次见到她就认为她很诚实”。

13. 选C。in case 意为“以防”。

14. 选D。when 不表示“当……的时候”，而表示“既然”，相当于since，用以引导原因状语从句。全句意为：你既然已经有了这么好的工作，干吗还要找新的工作呢? 请再两例：

I can’t tell you when you won’t listen. 既然你不想听，我就不告诉你了。

Why use wood when you can use plastic? 既然能用塑料，为什么还要用木料?

15. 选A。than 后省略了he was，假若补充完整，全句即为He is better than he was when I last visited him。

16. 选B。比较四个选项：so long as(只要)，even though(即使)，since(自从，既然)，while(当……时候)，其中只有B的意思最合适，全句意为“即使处罚不公平，他毫无怨言地接受”。

17. 选A。while 在此不表示“当……的时候”，而表示“尽管”。

18. 选B。as far as 意为“尽，就，至于”，常用于as far as I know(据我所知)，as far as one can see(在某人看来)，as far as one can(某人尽力)，as far as sth / sb is concerned(就某事/ 某人来说)等结构。

19. 选C。however 在此引导让步状语从句，意义上相当于now matter how。

20. 选C。so that 引导目的状语从句，其意为“为了”。

21. 选D。根据句子语境，选B 或D 较适合，但even 是副词，不是连词，不能引导状语从句，故选D。

22. 选D。问句的基本结构是“It is +时间段+since 从句”，其原句型是I suppose it is no more than half a month since he left for Japan. 假若对此句中的no more than half a month 提问，则可得到提问句。

23. 选D。what 引导的是主语从句，其中的what 相当于the schools that。

（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.

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：
