专题五 状语从句
I、重点难点解析
状语从句是由从句担任的 状语,在句子中可修饰谓语(或其它动词)、形容词、副词或是整个句子,它可以用
来表示时间、地点、 原因、目的、结果、条件、方式、比较、让步等。高考中已考查了时间、让步、地点、条件、
目的等状语 从句,不同的状语从句所使用的连接词也各不相同。见下表:
状语从句名称
时间状语从句
连接词
when, as, while, whenever, after, before, till (until), since, once, as soon as (或the moment ), by the
time, no sooner … than, hardly (scarcely) … when, every time等
地点状语从句
条件状语从句
原因状语从句
结果状语从句
目的状语从句
让步状语从句
where 和wherever
if, unless, so (as) long as, on condition that, so (as) far as, if only ( = if )
because, since, as, now that(既然)
so that (从句谓语一般没有情态动词), so … that, such … that
so, so that(从句谓语常有情态动词), in order that, in case(以防,以免)
although, though, as, even if (though), however, whatever, whether … or, no matter who (when,
what, …) 等
比较状语从句
方式状语从句
than, so (as) … as, the more … the more
as, as if (though), the way, rather than等
一、时间状语从句w。
1、当while, when, as引导时间状语从句时的区别:
(1) while引导的状语从句中动词必须是持续性。谓语动词多为进行时,或状态动词的一般时。while 的这些用
法可用when代替。E.g. Please keep quiet while (when) others are studying;
(2) when除可指一段时间外,还可用来指一点时间,等于 “at the time”,也就是说when引出 的时间状语从句
中的谓语动词可以是终止性的,也可以延续性的。因此主句和从句的谓语可以是一般时, 进行时,或完成时。
E.g. When I went into the lab, the teacher was doing an experiment.(when不能换成while)He often makes mistakes
when he is speaking English.(when可换成while)
(3) as常可与when,while通用,但强调“一边、一边”。E.g. As (when, while) I was walking down the street, I noticed
a police car in front of number 37.
(4) when有时代替if,引导条件句,意为“如果”、“假如” E.g. I’ll come when (if) I’m free.
2、till, until引导时间状语短语或状语从句,用于否定句时,结构为not …until (till),主句谓 语动词延续与非延续皆
可,意为“直到…才…”。用于肯定句时,只与延续性动词连用,表示“到…为止 ”。E.g. They played volleyball until (till)
it got dark. They didn’t talk(延续性动词)until (till) the interpreter(译员)came. He didn’t go to bed(非延续性动词)
until (till) the his father came back.;until可以放在句首,till则不行,E.g. Until the last minute of the match we kept on
playing. Not until he finished his work did he go home.(倒装);till, until只用于时间,以下句子是错误的:We walked
till the edge of the forest.(要用as far as或to)。
二、地点状语从句
引导地点状语从句的连词是where 和wherever等。E.g. Sit wherever you like.
Make a mark where you have a question.
第 1 页 共 6 页


三、条件状语从句
条件状语从句分真实性(有可能实现的事情)与非真实性 (条件与事实相反或者在说话者看来不大可能实现的
事情)条件句。引导条件状语从句的词(组)主要有 if, unless, so (as) long as, on condition that, so (as) far as, if only ( =
if )。注意:条件从句中的if 不能用whether替换。




E.g. If he is not in the office, he must be out for lunch.




You may borrow the book so long as you keep it clean.
So far as I know(据我所知), he will be away for three months.
You can go swimming on condition that ( = if ) you don’t go too far away from the river bank.
If he had come a few minutes earlier, he could have seen her.
四、原因状语从句
because, since, as引导原因状语时注意使用上的区别:
1.如果原因构成句子的最主要部分,一般用because ,因此because引导的从句往往放在句末。用why提问的句子,一
定用because回答。
E.g. He had to stay at home yesterday because he was ill.;2.如原因已为人们所知,或不如句子的其他部分重要,
就用as,或 since。since比as更正式些。as和since引导的从句一般放在句子的开头。
E.g. As you are tired, you had better rest. Since everyone is here, now let’s begin.
五、结果状语从句
结果状语从句是表示事态结果的从句,通常主句是原因,从句是结果。由so that (从句谓语一般没有情态动
词), so … that, such … that等引导。



E.g. She was ill, so that she didn’t attend the meeting.


He was so excited that he could not say a word.
She is such a good teacher that everyone admires her.
六、目的状语从句
引导目的状语从句最常用的词(组)是so, so that(从句谓语常有情态动词), in order that, in case(以防,以免)
等。
E.g. Speak clearly, so that they may understand you.


She has bought the book in order that she could follow the TV lessons.
He left early in case he should miss the train.
七、让步状语从句
让步状语从句可由although, though, as, even if (though), however, whatever, whether … or, no matter who (when,
what, …) 等引导。注意:as引导的让步状语从句一般是倒装的。



E.g. Though he is a child, he knows a lot.


Child as he is, he knows a lot.
Whatever ( = No matter what ) you say, I’ll never change my mind.
八、比较状语从句
比较状语从句常用than, so (as) … as, the more … the more等引导。
第 2 页 共 6 页





E.g. I have made a lot more mistakes than you have.


He smokes cigarettes as expensive as he can afford.
The busier he is, the happier he feels.
九、方式状语从句



方式状语从句常由as, as if (though), the way, rather than等引导。
E.g. You must do the exercise as I show you.
He acted as if nothing had happened.
十、使用状语从句时要注意的几个问题




1、在时间和条件(有时也在方式、让步等)从句中,主句是一般将来时,从句通常用一般现 在时表示将来。
E.g. We’ll go outing if it doesn’t rain tomorrow.
I’ll write to you as soon as I get to Shanghai.
2、有些时间、地点、条件、方式或让步从句,如果从句的主语与 主句主语一致(或虽不一致,是it),从句的
谓语又包含动词be ,就可省略从句中的“主语 + be”部分。




E.g. When (he was) still a boy of ten, he had to work day and night.


If (you are) asked you may come in.
If (it is) necessary I’ll explain to you again.
3、注意区分不同从句:引导的是什么从句,不仅要根据连词,还要根据句子结构和句意 来判别。以where为
例,能引导多种从句。





E.g. You are to find it where you left it.(地点状语从句)




Tell me the address where he lives.(定语从句,句中有先行词)
I don’t know where he came from.(宾语从句)
Where he has gone is not known yet.(主语从句)
This place is where they once hid.(表语从句)
4、as作从属连词可引导多种状语从句。
(1)as引导时间状语从句,意为“当…时”。例如:As (he was) a young man, he was a storekeeper and later a
postmaster. He sang as he worked. 高.考.资.源.网
(2)as引导方式状语从句,意为“象…一样”。例如:We must do as the Party teaches us.
(3)as引导原因状语从句。意为“由于”,例如:As you are tired, you had better rest.
(4)as引导让步状语从句。意为“虽然”、“尽管”Child as he is, he can do it well. ( = Although he is a child, he can do
it well.)
另外,
as做为关系代词还可以引导定语从句,如:I have the same book as you.
