初中英语状语从句经典版(整理后的)

状语从句指句子用作状语时，起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状
语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比
较等从句。 状语从句一般由连词(从属连词)引导，也可以由词组引起。从句位于句首或句中
时通常用逗号与主句隔 开，位于句尾时可以不用逗号隔开。
一、时间状语从句
要点: 时间状语从句，由以下连词引导：
when while as after before as soon as since till until by the time 在时间状语从句中，要注意时
态一致。一般情况下主句是将来时的时候，从句要用一般现在时。
当。。。的时候Mozart started writing music when he was four years old.(当)莫扎特的
时候，开始写音乐作品。
当。。。时He visited a lot of places while he was traveling.他在旅途中参观了许多地方。
在。。。的同时；一边。。。一边。。。
He smiled as he stood up.他一边站起来一边笑着。
在。。。之后
He left the classroom after he had finished his homework the other day.
前几天做完作业之后回的家。
在。。。之前
Mr. brown had worked in a bank for a year before he came here.
布朗先生来这之前已经在一家银行里工作一年了。
soon as 一??就??We began to work as soon as we got there.我们一到那就开始工作。
I will write to you as soon as I get home. 我一到家就给你写信。
自??以来 到现在
表示自过去的一个起点时间到目前(说话时间 )为止的一段持续时间。主句一般用现在完成
时，从句用一般过去时。
Mr green has taught in that school since he came to china three years ago.
自格林先生来中国以来，他就在这所学校教书。
(还可以用作介词，本句从句还可以用短语：since three years ago(自三年前以来)表示。)
8 .till until都可以作连词，连接时间状语，也可以 作介词，与其它词构成介词短语，在句中
作状语。(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)
They walked till until it was dark.他们一直走到天黑。
Xiao ming didn’t leave home till until his father came back.小明直到他爸爸回来才离开家。
9. by the time 到??为止 (所在句子的主句应用完成时)
By the time he gets there , his father has already gone.他到家的时候，他爸爸已经走了。
By the time i got to school, the class had already began.我到校时，已经开始上课了。
难点——as when while的辨析
as when while都表示主、从句动作同时发生，三者差异如下：
表示“一边。。。一边＂的意思
as 强调两个动作同时进行，并表示对比时 用于发生时间较段时
when 1、还可以表示从句动词的动作在主几句动词的动作＂之前 ＂或＂之后＂发生。
2、when＝and then; at that moment (正在那个时候)while a、用于时间较长时b、 强调两个动
作同时进行，并表示对比时有时这三个连词可以互换，有时不可以。
It was raining hard when (as) I got there.

我到那里时，正在下大雨。 ( 动作同时发生，when可换为as, 但不能换为while，因为get
是瞬间动词.)
When I had read the article, he called me.
我看完这篇文章之后，她给我打了电话。( 从句动作发生在主句之前，注意时态表达，只能
用when )
When I got to the cinema, the film had begun.
(当)我到了电影院时，电影已 经开演了。(从句的动作发生在主句之后，只能用when,并要注
意时态)
He was about to leave, when the telephone rang.
他正要离开，忽然电话响了。( 此时不能放在句首。主句动词一般表达 “正在” “即将”.
while, as不能代替 ) 考点

它) 考点
While the alien was buying a souvenir, the girl called the police.
外星人买纪念品时 ，那女孩给警察打了电话。(表示主句，从句的动作同时发生，while后引
导的状语从句的动词必须 是延续动词不能是点动词，因为它表示较长时间,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）。)考点
Mother was worried because little alice was ill, especially as (when while) father was away.
妈妈担心，因为小爱丽丝病了，特别是他父亲不在家的时候。(此时as ,when, while可通用)
知识扩展
is ?since从??以来多长时间了(因为since +从句或名词，表示一段时间)

2. It is? +before…(??才)

while与but的句中用意
1)Some people waste food while others haven't enough.
有些人很费粮食，然而有些人却吃不饱。
2)The son was having a good meal at home，while the parents were working in the fields.

b.引起条件状语，意思是“只要”

c.引起让步状语从句，意思是“虽然?但是?.”、“尽管?但是?”(多放于句首)

二、条件状语从句
要点： 表示状语从句由连词if, unless (=if not) 引导。

will get good grades if you study hard.如果你努力学习,就会取得好成绩.

3.I will go to the party unless he goes there too.
我不会去参加聚会的, 除非他也去.(如果他不去,我也不去.)
will be late unless you leave immediately.
如果你不马上走,你将会迟到的.(=if you don’t leave immediately, you will be late.)
难点 提示：用条件状语从句时要注意时态的正确使用,当主句是将来时的时候,从句要用一般
现在时(时间、 条件状语从句中用一般现在表示将来考点).
He will not leave if it isn’t fine tomorrow.
They are going to have a picnic if it doesn’t rain next week.
(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 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.
三、原因状语从句
要点: 由连词because, since, as引导, 也可由for, now that 等词引导

2. Since everybody is here, let’s begin our meeting.既然大家都来了, 让我们开始开会吧.
3. As you are in poor health, you should not stay up late.既然你身体不好, 你就不该熬夜.
her to stay to tea, for I had something to tell her.

.难点——because , since , as , for,辨析
在语气上，because 最重, 表示的是直接理由,回答why 时只能用它. 其次是since, as ,一般不
表示原因, 而是表明理由, 进一步说明.(译为：由于，既然). for 被认为是复合句的并列连词
(常用于推断),表示理由.
四、地点状语从句
要点: 由连词where和复合关系词wherever (=no matter where )引导.
知识扩展
there is a will , there is a way.有志者事竟成。(谚语)
will be mixed school where not all the children are disabled.
他将是一所混合式学校， 那里的儿童并不都是残疾。(在限定性定语从句中对限先行词起限
定作用。)
er you go , i go too.无论你到什么地方，我都去。(wherever=no matter where)无论何
处，多用于句首。
er there is smoke , there is fire.无风不起浪。(谚语)
4. While she was wondering where to go , she met a policeman. 疑问副词where后跟不定式,构
成不定式短语. 考点
五、目的，结果状语从句
要点： 目的状语从句由连词that, so that, so…that , in order that 引导。
结果状语从句由连词( so )that, so…that, such…that, so muchmany…that引导。
…that 如此…以至于
The scientist’s report was so instructive that we were all very excited.
科学家的报告很有启发性，我们感到很兴奋。

步。
that 以至, 以便

3. such…that 如此。。。以至

园玩。
order that=so that:为了
We shall let you know the details soon in order that you canmay make your arrangements.
不久我们将会让你知道详情,以便你们能够做出安排。(目的)
难点
+形容词或副词
+形+a(an)+单数可数名词
so +many 或few+复数可数名词 +that
+much或 little+不可数名词
lso that ,such…that 都可以in order that两者皆可引导目的地状语从句和结果状语从句，
当他们引导目的状语从句时，从句的谓语里常常有can, could, may, might, will, would等次。
(见例句 2, 5 )
so +.+ that， such +n.+ that 以上两种句型都表示结果,其中so为副词,后接形容词，
副词原型，当可数名词前有many, few；不可数名词前有much, little修饰时，应采用句型：
so many (few, much, little )+n. 。 （如果名词前由many, much, little, few等词修饰时，只能
用so, 不用such）。such为形容词, 后只能接名词。这名词既可 以是可数的，也可以是不可
数的。如果这名词是可数,单数,则必须在名词前敬爱冠词a(an). 常见的形式是:such a
(beautiful)garden, such(nice)people.
The weather is so nice that I’d like to take a walk. 天气是如此只好,以至于我想去散散步.
Mike is so honest a man that we all believe him.
麦克是如此诚实的一个人,以至于大家都相信他

It is such nice weather that I’d like to take a walk.天气是如此只好,以至于我想去散散步. 考点

all of us wanted to see it again. It is such an important match that nobody wants to miss it. =The m
atch is so important that nobody wants to miss it.
六、让步状语从句
要点: 表示让步的状语从句由连词 though, although引导.
难点：
though, although当虽然讲, 都不能和but连用. although,(though)…but的格式是不对的.但是他
们都可以同yet (still) 连用. 所以thought (although)…yet(still)的格式是正确的.
wrong: although he is rich but he is not happy.
right : although he is rich, yet he is not happy.虽然他很富有, 然而他并不快乐.
right : although we have grown up, our parents treat us as children.
right : although we have grown up, our parents still treat us as children.
尽管我们已经长大了,可是我们的父母仍把我们看作小孩.
although, though 辨析
although 不能像though 那样用作副词, 放在句末表示强调时要用even though.
He is looking fit, though.但是,他看上去很健康. 考点

Even though（即使） I didn’t under a word, I kept trying to understang.尽管我一个字也不懂，
我还是一直微笑着。
He is quite experienced, he is young, though.尽管他很年轻，他很有经验。
