高中英语状语从句讲解及练习

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)W hen

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)A s

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)W hile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.unless 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 mo ney 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.

注意点：

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

九方式状语从句

EG：Just do as you are told.

The workers went on working as if nothing had happened.

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。

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”

专题十一状语从句 状语从句在高考试题中由于其他从句的干扰，以及倒装句，强调句的介入，使得状语从句更为复杂。状语从句是一种副词性从句，通常由一个从属连词或一个起连词作用的词组引导。状语从句 1. 时间状语从句 常见的连词(组)： when, while, as, before, after, once, till, until, as soon as, now that, hardly ...when, scarcely ...when, no sooner ...than等。 可以引导时间状语从句的副（介）词（短语）或名词短语： directly, instantly, immediately, by the time, the moment, the second, the minute, the instant, every time, each time, next time, the last time等。 注意点如下： (1) when, while, as引导的时间状语从句 as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。when(at or during the time)既可以表示在某一点的时候，又可以表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。while强调一段时间，仅表示从句和主句的动作同时发生，并且有延续意义，该从句中的动词一般要用延续性动词，从句中常用过去进行时态或一般过去时态；当when表示a period of time时，两者可以互换。 She came up as I was cooking.(同时) 在我做饭时，她走了过来。 When we were at school, we went to the library every day.(在一段时间内) 当我们在学校时，每天都去图书馆。 While they were watching TV, I was preparing myself for the coming examination. 他们在看电视，而我在为即将到来的考试做准备。 Strike while the iron is hot. 趁热打铁。( 不可用as或when，这里的while意思是“趁……”) (2) before引导状语从句时的常见重点句型 ①It will (not) be ...before ... 还要……才，要不了多久就…… It was (not) ...before ... 过了……才(没多久就……) It was a long time before I got to sleep. 过了好长时间我才睡着了。 It wasn t long before he told me about the news. 没多久他就告诉了我那条新闻。 ②不等……就……；在……之前就…… The telephone rang off before I could answer it. 我还没来得及接电话，电话就挂断了。 ③刚……就…… He hardly entered the room before he heard the telephone ring. 他刚进屋电话铃就响了。

(完整版)初中英语语法专题(状语从句)讲解

初中英语语法专题（状语从句）讲解 状语从句在复合句中作状语，修饰动词、形容词或副词等。状语从句可以表示时间、条件、原因、地点、目的、结果、让步、方式、比较等意义。 知识梳理：提纲挈领，抓住重点和难点！ 各类状语从句连接词（短语）一览表： 时间 when, while, as, as soon as, since, until, after, before 条件 If, unless 原因 As, because, since 地点 Where 目的 So that, in order that 结果So that, so…that, such…that 让步 though, although, even if, however 方式 As 比较 t han, (not)as…as, 时间状语从句： Whenever he comes, he brings a friend. 他每次来都带个朋友。 条件状语从句： As long as I am alive, I will go on studying. 只要我活着，我就要学习。 原因状语从句： Since we live near the sea, we enjoy nice weather.由于我们住在海边，能享受到好的天气。 地点状语从句： Put it where we can all see it.把它放在我们都能看到的位置。 目的状语从句：

When (While) we were at school, we went to the library every day. While表示时间段,因此，while 从句的谓语动词要用延续性动词。如： Please don't talk so loud while others are working. As与when用法相似，但着重强调主句动作与从句动作同时发生，有"随着……"或"一边……一边……"之意。如： As you get older, you get more knowledge.随着年龄的增长，你获得的知识就越多。 2．Because,as,since 的区别： Because用于表示直接原因,回答why提出的问题，语气最强；As用于说明原因, 着重点在主句，常译成"由于"；since表示显然的或已知的理由或事实，常译成"既然"。如： Water is very important because we can't live without it. He didn't come yesterday as his mother was ill. I'll do it for you since you are busy.

状语从句用法讲解和练习

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：

高中状语从句讲解+练习 状语通常由副词、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） 状语从句主要用来修饰主句或主句的谓语。一般可分为九大类，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, the instant, immediately , directly, every time, the day，no sooner …than, hardly …when, scarcely …when （1）Tell him I need to see him the minute he arrives. 他一到就告诉他我要见他。 （2）The children ran away from the orchard(果园) the moment they saw the guard. The moment he saw me, he ran away. 他一看见我，就跑了。 He said he’d call you the moment he got home. 他说他一到家就给你打电话 （3）The instant I saw him, I knew he was the man from the restaurant. （4）Immediately you begin to speak, he gives you his full attention.你只要一开始说话，他就全神贯注地听。 （5）My sister came directly she got my message. 我妹妹一收到我的信息就来了。 （6）Every time I listen to your advice, I get into trouble. （7）no sooner... than... ，"一...就..." ，引导时间状语从句,主句用过去完成时,"than"后面的从句用一般过去时.(从这里可以知道,no sooner后面是主句;than后面是从句) 例: I had no sooner reached home than it began to rain. 我一到家天就下起雨来 No sooner ...than...常放在句首,表示强调.这时主句要倒装. 例:No sooner had I reached home than it began to rain. （8）He had hardly sat down when the telephone rang.他刚坐下电话就响了。 He had scarcely sat down when there was a knock at the door. 他刚坐下就有人敲门 另外，如果把hardly放于句首，主句要用倒装结构。如： Hardly had I finished eating when he came in. 我刚吃完他就进来了。 2．地点状语从句 常用引导词：where 特殊引导词：wherever, anywhere, everywhere Generally, air will be heavily polluted where there are factories.
