中考英语状语从句用法分类详解

一、状语从句的概念
用来修饰主句中的动词，副词和形容词的从句叫状语从句。

二、状语从句的分类
根据其含义状语从句可分为时间状语从句，地点状语从句，条件状语从句， 原因状语从句，结果状语从句，比较状语从句，目的状语从句，让步状语从句。

三、状语从句的句法功能

1. 时间状语从句（主句将来时从句现在时）

1)时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导。例如：
It was raining hard when got to school yesterday.
While he was doing his homework, the telephone rang.
As he walked along the lake, he sang happily.
He had learned a little Chinese before he came to China.
After he finished middle school, he went to work in a factory.

易混引导词while, when的区别：
　　when既可以指"时间点",与瞬间动词连用，也可以指"时间段"，与延续性动词连用（=while）。
While表示时间段,因此，while 从句的谓语动词要用延续性动词。

练习：用while或when填空
1. Please don't talk so loud ______ others are working.
2. ______ he came in, his mother was cooking.
3. ______ we were at school, we went to the library every day.
Keys: 1. while 2. when 2. While

2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。

练习：
1. I’ll ring you up as soon as I ______（get） to New York.
2 .I will tell him everything when he ______ (come) back.
3. He won’t believe it until he ______ (see) it with his own eyes.
Keys: 1. get 2. comes 3. sees

结论: 主将从现的原则

3)在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是“一直到……时”，谓语动词只能用延续性动词。如果主句用否定式，其含义是“直到……才……”, “在……以前不……”, 谓语动词可用瞬间动词。

例如：（注意粗体单词）
11.The young man read till the light went out.
12.Let’s wait until the rain stops.
13.We won’t start until Bob comes.
14.Don’t get off until the bus stops.

2. 条件状语从句（主句用将来时从句用现在时）

1)条件状语从句通常由if, unless引导。例如：
What shall we do if it snows tomorrow?
Don’t leave the building unless I tell you to.

2)在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。
练习：
1. I’ll help you with your English if I ______(be) free tomorrow.
2. He ______(not) be late unless he is ill.
Keys: 1. am 2. will not

3)“祈使句 + and (or)+ 陈述句” 在意思上相当于一个带有条件状语从句的复合句。例如：
Hurry up, or （其中文意思是什么）you’ll be late.
=If you don’t hurry up, you’ll be late.
Study hard and you will pass the exam.
=If you study hard, you will pass the exam.
批注：需要让学生理解祈使句也是个句子，只是省略主语的句子，汉语中也较多此类句型，可以类比讲解。

3. 原因状语从句

1)原因状语从句通常由because, since（因为）, as（因为）引导。例如：
He didn’t come to school because he was ill.
As it is raining, we shall not go the zoo.
Since you can’t answer the question, I’ll ask someone else.

2)because表示直接原因，语气最强。Because引导的原因状语从句多放在主句之后。回答由why提出的问题，只能用because。As和since语气较弱，一般用来表示明显的原因。由as和since引导的原因状语从居多放在句首。例如：
------Why aren’t going there?
------Because I don’t want to.
As he has no car, he can’t get there easily.
Since we have no money, we can’t buy it.

3)because和so不能同用在一个句子里。

4. 结果状语从句

1)结果状语从句由so…that, such…that, so that引导。

练习：
1. He is ______ poor that he can’t buy a bike for his son.
A． so B. such C. much D .too
2. She is ______good teacher that everybody likes her.
A .such a B. so a C. a so D .a such
Keys: A A

2)so…that语such...that可以互换。例如：
在由so...that引导的结果状语从句中，so是副词，与形容词连用。其结构是:
“...so + 形容词（副词）+ that + 从句”。

例如：
He was so glad that he couldn’t say a word.
The hall is so big that it can hold 2,000 people.
Mother lives so far away that we hardly ever see her.

在由such…that引导的结果状语从句中，such是形容词，它修饰的可以是单数或复数可数名词，也可以是不可数名词；名词前面可以带形容词，也可不带。如果是单数可数名词，前面需加不定冠词a或an。例如：
It was such a hot day that nobody wanted to do anything.
He had such long arms that he could almost touch the ceiling.
He made such rapid progress that he did very well in the mid-term.
有时上述两种结构是可以互换的。

练习：（选出划线部分的近义选项）
1）It was such a wonderful film that all of us wanted to see it again.
A so wonderful a film B so a wonderful film
2）It is such an important match that nobody wants to miss it.
A so an important match B an so important match C so important a match
Keys: A C

(3)如果名词前由many, much, little, few等词修饰时，只能用so, 不用such。

练习：
Soon there were ______ many deer that they ate up all the wild roses. Keys: A
A so B such C much
总结：
① so +形容词或者副词+that…
② such +(形容词)+可数名词或者不可数名词 + that
③ such +a/an +形容词+可数名词单数
= so+形容词 +a/an +可数名词单数
④so + little/ many/much/ few +名词

5. 比较状语从句
比较状语从句通常由as…as, 比较级 + than…等连词引导。例如：
Tom runs faster than John does.
This classroom is as big as that one.
批注：这里需要强调两个as后面接的词性是不同的，且第一个as后面接的必须是形容词和副词的原级，这是考试的
重点；与此不同的是，than前面必须是形容词和副词的比较级形式。

6. 目的状语从句

1)目的状语从句通常由 so that, in order that引导。例如：
We started early so that we could catch the first train.
He studies hard so that he could work better in the future.
We used the computer in order that we might save time.

2)so that既可引导目的状语从句，又可引导结果状语从句。区别这两种从句的办法有两个：
目的状语从句里往往带有情态动词can, could, may, might等。
从意思上看，目的状语从句往往表示的目的很明确。例如：
Speak clearly so that they may understand you. (目的状语从句)
Jack is badly ill so that he has to rest. (结果状语从句)
批注：这里主要引导学生从意思的角度进行区分，比如第二个句子，生病的目的不可能是为了休息，不符合正常的逻辑。

7. 让步状语从句

1)让步状语从句通常由although, though，even though，even if，no matter，however等连词引导。例如：
1.Though he is young, he knows a lot.
2. Although／Though／Even though／Even if you don’t like him you can still be polite．
尽管／即使／纵然／即使你不喜欢他，你仍可有礼貌一些。
3. No matter what you do(Whatever your do)，don’t touch this switch．
无论怎样，都别碰这个按钮。
4. However rich people are(=No matter how rich people are )，they always seem anxious to make more money．
无论人们多么富有，他们似乎总还渴望赚到更多的钱。
5. However carefully you drive，you will probably have an accident eventually．
无论你开车多小心，最后你大概还会出车祸。
6. Whatever you do，don’t tell him that I told you this．
无论如何，别跟他说这件事是我告诉你的。

2)although(though)和but不能用在同一个句子中。例如：
我们不能说：Though it was raining hard, but he still went out.
应该说：Though it was raining hard, he still went out. 或 It was raining hard, but he still went out.
批注：这是英语和汉语说话习惯不同的地方，需要重点讲解。另外，可以类比地讲解“因为和所以不能出现在同一
个句子中”。

8. 地点状语从句
地点状语从句常常由where来引导。例如：
Go where you like.
Where there is a will, there is a way.
批注：这属于比较难的知识点，学生理解即可。

实例解析

1.You will stay healthy _______ you do more exercise, such as running and walking.
A. if B. how C. before D. where

All the best,
Li Hua
【答案】Dear Danny,
I’m glad to receive your letter. Since you are interested in civilization(文明) of China, I would like to share something with you.
Chinese civilization is one of the oldest and longest civilizations in the world. China is a country of 56 nationalities. Different nations have difficult cultures. In my country, we have many traditional festivals, such as, the Spring Festival, Mid-Autumn Festival and the Dragon Boat Festival . They are also called “three major Chinese holidays” in China. Here are the customs of eating Zongzi and racing dragon-boat on the Dragon Boat Festival.
China is a nation of etiquette (礼仪). Chinese people can respect, trust and help each other. We all learn and grow together. Everyone in my school should protect the whole public environment. Climbing the trees, picking the flowers and throwing garbage at random are not allowed there.
I hope you can come to China someday to experience the ancient culture of China. Look forward to hearing from you soon.
All the best.
Li Hua
