从句是相对于主句而言的,即它是从属于某一个主句,而不能单独作一个句子。在英语中主要有三大从句,即:1. 名词性从句(包括主语从句,宾语从句,表语从句,同位语从句)2. 定语从句3. 状语从句(包括时间、条件、结果、目的、原因、让步、地点、方式等)。1)主语从句用作主语,如: That the earth is round is true. 地球是圆的是真实的。2)宾语从句用作宾语。如: Do you know where he lives?3)表语从句用作表语,如: My opinion is that you should not go alone. 我的意见是你不应单独前往。4)同位语从句用于解释说明前面的名词。如: The fact that the earth is round is true. 地球是圆的的事实是真实的。(that从句用于解释说明the fact)5)定语从句相当于一个形容词,用于修饰前面的名词。如: The student who answered the question was John. 回答问题的学生是John.6)状语从句相当于一个副词,如: When it rains, I usually go to school by bus. 天下雨时,我通常坐公共汽车上学。(时间状语) If he comes tomorrow, you will see him. 如果他明天来,你就可以看见他。(if 引导的条件状语从句,其结构为:if +状语从句,+主句)。要注意在状语从句中有一个规则是“主将从现”,即主句是将来时,则从句要用一般现在时表示将来。 He returned home to learn his daughter had just been engaged.他回家后得知女儿刚刚订婚了。(结果状语,结果状语只是仅限于learn(得知),find(发现),see,hear,to be told(被告知),make(使得)等具有界限含义的动词。) You must speak louder so that /in order that you can be heard by all. 你必须大声说话,才能让所有人听到你说话。(目的状语,可以由that, so that, in order that, lest, for fear that, in case等词引导。) Since /As the weather is so bad, we have to delay our journey. 天气那么糟,旅行推迟了。 (原因状语从句,常用 because, since, as, for fear (恐怕), seeing that (既然) ,now that (=since), considering that (考虑到) 等引导。) Though/Though he was worn out, (still) he kept on working. 虽然他已经精疲力竭了,但仍然继续工作。(让步状语从句,引导的连词主要有以下这些:though, although, as; even if, even though; whether...or...; no matter+疑问词,疑问词-ever.) Where I live there are plenty of trees. 我住的地方树很多。(地点状语从句,通常由where, wherever 引导。) As water is to fish, so air is to man. 我们离不开空气,犹如鱼儿离不开水。(方式状语从句通常由as, (just) as…so…, as if, as though引导。) 主句和从句的划分方法是相同的。句子的成分从谓语动词处来划分比较容易。谓语动词前面的部分是主语,后面常接宾语,修饰谓语动词的是状语,修饰主语、宾语的是定语,若谓语是系动词,则系动词后的部分是表语。如: I am a teacher. 其中,I 是主语,am是谓语,a teacher 是表语。 He likes playing football very much. 其中,he是主语,likes是谓语,playing football是宾语,very much是状语。

状语从句是英语语法中的常用句型语法,那么大家是否清楚什么是状语从句呢?下面就是我给大家带来的初中英语状语从句详细解析,希望能帮助到大家!

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。
