状语从句知识点详解(初中英语专项复习)状语从句的概念: 用一个句子作状语来修饰动词和形容词,以表明动作发生或状态存在的时间、地点、原因等,这个句子就叫做状语从句。
状语从句的分类:状语从句共分为九大类,包括:时间、地点、原因、条件、让步、目的、结果、方式、比较状语从句。
下面分别讲解:一、时间状语从句概念:用来表示时间的状语从句,由when, while, as, till, until,before, after, since等引导。
由于时间状语从句的引导词所表示的意思并非一致,不同引导词表达不同的时间,它们在句子中对应的时态、语态等也有所不同。
例如:when /while引导的时间状语从句when引导的从句的谓语动词通常是瞬间动词,也可以是延续性动词。
从句动作可与主语动作通常先后发生也可同时发生。
I was writing when my sister came back.( come是瞬间动词,只能用when引导,不能用while)He often wrote me when/while he studied in Shanghai International Studies University.( study 是延续性动词,while可代替when)While my mother was cooking , I was playing chess with dad. (cook是延续性的动词,cook和play同时发生)I like playing chess while my sister likes reading stories.我喜欢下棋,而我姐姐喜欢看小说。
(while表示对比)when和while的区别还有:while引导的时间状语从句多用于进行时态,而when引导的时间状语从句多用于一般时态。
While we were playing games, our headmaster called me .我们正在做游戏的时候,校长叫我了。

初中英语状语从句嗨,小伙伴们!今天咱们就来好好唠唠初中英语里超级重要的状语从句。
这就像是在英语这个大冒险里的魔法钥匙,一旦掌握了,那可不得了。
我记得我刚学英语的时候,状语从句就像一团迷雾。
比如说时间状语从句,“When I was young, I liked reading storybooks.”(当我小的时候,我喜欢读故事书。
)就这么一个简单的句子,“when”引导的这个时间状语从句就像是给这个事情定了个时间的框架。
想象一下,时间就像一条长长的河流,这个从句就像是在河流上标记了一个点,告诉我们事情发生的时间。
你们有没有觉得很神奇呢?就像我们生活中的闹钟,它会在特定的时间响起来,时间状语从句也是这样,到了那个“时间点”,主句里的动作就开始或者发生了。
再来说说条件状语从句,像“If it rains tomorrow, we will stay at home.”(如果明天下雨,我们就会待在家里。
)这就像是一个约定,“if”就像是一个魔法开关。
如果满足了这个“if”后面的条件,就会有主句里的结果。
这多像我们玩游戏啊,如果你达到了某个关卡的要求,你就能解锁下一关的内容。
要是不理解这个条件状语从句,就好像在游戏里乱撞,根本不知道怎么通关。
你们在学习这个的时候,是不是也有这种感觉呢?我有个同学叫小明,他对原因状语从句就很头疼。
“Because he was ill, he didn't go to school.”(因为他生病了,他没有去上学。
)这个“because”引导的从句是用来解释主句发生的原因的。
我就跟小明说啊,你就把它想象成侦探破案。
主句是案件的结果,而原因状语从句就是破案的线索。
你得找到这个线索,才能明白为什么会有那样的结果。
小明听了我的话,就好像突然开窍了一样,眼睛都亮了起来。
还有让步状语从句呢,像“Al though he is young, he can do a lot of things.”(虽然他很年轻,但他能做很多事情。

初中英语状语从句详细解析
状语从句详细解析
一、什么是状语、状语从句?
状语:是用来修饰动词、形容词、副词或全句用的。
eg:He works hard! (他努力工作)中的hard。
状语的位置:
修饰形容词或副词的状语放在被修饰语之前。
eg:The Summer Palace is very beautiful.颐和园非常美丽。
(very 为状语,修饰形容词 beautiful,放在 beautiful 之前)。
修饰动词的状语有的放在动词前,有的放在动词之后。
如果动词有宾语,状语一般须放在宾语之后。
eg: I He often came here to see me.他经常到这里来看我。(often 为状
语,修饰动词came,放在前面)。
I know him well.我十分了解他。(well为状语,修饰动词 know,放在 know
之后)。
状语从句:用一个句子(从句)来作另一个句子(主句)的状语,用作状语的句子
就叫作状语从句。作什么样的状语就叫什么类型的状语从句。例如:条件状语
从句就是用一个句子来作条件状语。
二、状语从句的分类。
(1)时间状语从句
凡是从句都必须有引导词,引导时间状语从句的词有when,before,after,
until,as soon as,while 等,具体用法如下:
1. when 意为“当……时”,引导时间状语从句,表示主句的动作和从句的动
作同时或先后发生。
eg: I feel very happy when you come to see me.
When you are crossing the street,you must be careful.
when引导的时间状语从句,when的从句可以用延续性动词,也可以用瞬间动
词。
eg:He was working at the table when I went in. 。
Someone knocked at the door when I was sleeping.
I will visit my good friend when I have time.
注:when也可以作并列连词,表示一个动词正在进行的时候,突然间发生了另
外一件事。
eg: I was fishing by the river,when someone called for help.
We were working in the chemistry lab,when the lights went out.
2. before 意为“在……之前”,引导时间状语从句时,表示主句的动作发生
在从句的动作之前。 eg: We cleaned the classroom before we left school
yesterday.
He had been a cook before he went to college .
after 意为“在……之后”,引导时间状语从句时,表示主句的动作发生在从
句的动作之后。
eg: After you use plastic bags,you mustn't throw them about.
He called me after he had finished his work.
注:若主句和从句两个动作发生的先后顺序十分接近,那么也可以不用完成时
态,如上面的 第二句可改成:He called me after he finished his work.
3. since引导的时间状语从句,译为“自从……”,主句常用现在完成时,从
句常用一般过去时。
eg: I have taught English, since I came to Shenzhen.
注:常用句型:It is +时间段+since从句 译为:自从……有多长时间了。
eg. It is six years since she graduated from the university.
4. until 意为“直到……时”,引导时间状语从句时,表示主句的动作发生在
从句的动作之前。
当主句的谓语动词是持续性动词时,主句常用肯定形式;当主句的谓语动词是非
持续性动词时,从句常用否定形式,not…until… 意为“直到……才……”,
这时的until可以用before 来替换。
eg:I'll stay here until you come back.
我会呆在这里,直到你回来。 (stay表示的 动作可以持续)
He didn't go to bed until he finished his homework.
他直到做完作业才睡觉。(go to bed 表示的动作不能持续)
5. as soon as 意为“一……就……”,表示从句的动作一发生,主句的动作
马上就发生。
eg:I'll tell him about it as soon as he comes back.
6. while引导的时间状语从句,常译为“与……同时,在……期间”,while
的从句中常用延续性动词或表示状态的词。
eg. They rushed in while we were discussing problems.
Father was cleaning the car while I was playing computer games.
注:while也可以作并列连词,表转折的关系,相当于but,译为“然而”。
eg. I like listening to music,while my brother likes doing sports.
7. till和until引导的时间状语从句,译为“直到……为止”,not … till
/ until引导的时间状语从句,译为“直到……才”。前者强调主句动作的结
束,用延续性动词,后者强调主句动作的开始,用瞬间动词。
eg. I will wait for my friend until / till he comes. 我要一直等到我朋
友来。
We won't start our discussion until / till he comes.
我们要等到他来了,再开始我们的讨论。
(2)条件状语从句
1.条件状语从句通常由if, unless引导。
eg: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。(主将
从现)
eg:I’ll help you with your English if I am free tomorrow.
He won’t be late unless he is ill.
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。
eg: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.
(3) 原因状语从句
1.原因状语从句通常由because, since, as引导。
eg: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。
eg:------Why aren’t going there? ------Because I don’t want to.
As he has no car, he can’t get there easily.
3. because和so不能同用在一个句子里。
For 语气最弱,它所引导的分句必须放主句后面,引补充说明作用。
eg:Put on more clothes, for it's cold outside.
注:because, since, as, for 的区别
语气位置意义
because最强前或后 “原因”;表客观因果关系;回答“”
as 较强 前 “由于”;把众人所知的事实当作理由
since 较弱 前 “既然”;就对方陈述的事实作为理由
for 最弱 后 “理由”;对某一事实进行推断的理由
(4)地点状语从句
常用where(哪里)和wherever(无论哪里)
eg. Where there is a will,there is a way. 有志者,事竟成。
We will go wherever the motherland need us most. 我们要到祖国最需要的
地方去。
