初中英语从句精练

⑴ 初中英语从句整理

状语从句
状语从句用来修饰主句中的动词，副词和形容词的从句叫状语从句。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。
1. 时间状语从句
(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（rain hard下大雨） when got to school yesterday.
While he was doing his homework, the telephone rang.
As he walked along（沿着走） 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.
(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。例如：
I’ll ring you up as soon as I get to New York.
I will tell him everything when he comes back.
He won’t believe it until he sees it with his own eyes.
(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：
The young man read till the light went out（熄灭）.
Let’s wait until the rain stops.
We won’t start until Bob comes.
Don’t get off（从下来） until the bus stops.
【Till是指直到某一特定事件发生的时候，而在那个时刻之后，该事情或状况仍将持续。 Until是指直到某一特定事件发生的时候，而讲话的人在自己心里认为，在那个时刻之后，该事情或该状况将中止（不怎么可能持续）。固定组合里from morning till night，till/until是不能替换的，】
2. 条件状语从句
(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。例如：
I’ll help you with your English if 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。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.
3. 原因状语从句
(1)原因状语从句通常由because, since, as引导。例如：
He didn’t come to school because he was ill.
As it is raining, we shall not （不得；不应该）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。例如：
He is so poor that he can’t buy a bike for his son.
She is such a good teacher that everybody likes her.
My pencil fell under the desk, so that I couldn’t see it.
(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（几乎不，从来不） 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.（天花板）
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。例如：
It was such a wonderful film that all of us wanted to see it again.
=The film was so wonderful that all of us wanted to see it again.
It is such an important match that nobody wants to miss it.
=The match is so important that nobody wants to miss it.
(3)如果名词前由many, much, little, few等词修饰时，只能用so, 不用such。例如：
Soon there were so many deer that they ate up all the wild roses.
He has so little time that he can’t go to the cinema（去看电影） with you.
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.
6. 目的状语从句
(1)目的状语从句通常由 so that, in order that（为了，以便）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：1)目的状语从句里往往带有情态动词can, could, may, might等。2)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)
7. 让步状语从句
(1)让步状语从句通常由although, though等连词引导。例如：
Though he is young, he knows a lot.
Although I am tired, I must go on working.
(2)although(though)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.
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.

⑵ 求初中英语各类从句的用法

英语的复合句包括并列句和主从句两种。其中并列句是两句地位完全相同的简单句用表示并列关系的连词连接而成（例如and，or等）。主从句虽然有两套主谓结构，但是其中一套是主要的，称为主句，另一套只是充当主句的某个成分，称为从句。英语从句分为宾语从句，定语从句，状语从句，主语从句，表语从句，同位语从句6种。
宾语从句和表语从句
宾语从句和表语从句是从句中较为简单的一种。这两种从句是以句子的形式代替了主句中的宾语或表语，也就是直接占据了谓语后宾语或表语的位置，比较明显。引导宾语从句或表语从句的引导词最常用的是that，以及关系代词what，which，who(whom),关系副词when，where，how，whether。
由于主从复合句中有两套主谓结构，因而要注意时态的搭配。时态搭配的原则是从句服从主句，但是可以根据情况灵活配置，不过主从句之间不出现时段断层。因而一般常见的配置组合为：
主句 现在时 过去时 将来时
从句 现在时，过去时，将来时 过去的时态 一般现在时
注：当从句的内容是客观真理时，无论主句是什么时态，从句永远用一般现在时，例：The teacher told the students that the light travels faster than the sound in the air.
定语从句
定语从句是从句充当定语的用法，引导词与时态搭配的规则与宾语从句相同。定语从句与宾语从句区分的要点是宾语从句充当主句的宾语，占据了主句中宾语的位置，而定语从句的主句结构完整，定语从句在引导词的引导下跟在被修饰的主句的主语或宾语（表语）之后，起修饰作用，而被修饰的词语称为先行词。例如：
①People don’t know who runs in the morning in the park everyday.人们不知道是谁每天早晨在公园里跑步。
②People don’t know the man who runs in the morning in the park everyday.人们不知道那个每天早晨在公园里跑步的人是谁。
在②中，主句部分People don’t know the man句子结构是完整的，the man是被从句修饰的成分，即先行词。
注意，that是引导短语从句的引导词中最灵活而且用法最多的，通常可以代替所有关系代词（which，what，who，whom），而且有几种情况必须使用that：A.先行词是不定代词时；B.先行词受形容词最高级修饰时；C.当先行词被any, few, little, no, all, much, some等词修饰时D.当先行词为序数词或被序数词所修饰时；E.当先行词被the very, the only, the last, the just, the same等修饰时；F.当先行词既包含人又包含物时当先行词是疑问代词who，which，what或主句以这些词开头时；G.当先行词为主句表语或关系代词为从句表语时。
以下两种情况一般只使用which：在“介词＋关系代词”结构中先行词为“those＋表事物的复数名词”时。
当先行词为时间，地点或方式名词时，就有是使用关系代词和关系副词的问题了。原则非常简单：如果从句主谓宾结构完整，就使用关系副词；如果从句主谓宾结构不完整，使用关系代词。例如:
①This is the place where they met each other for the first time.
这是他们第一次见面的地方。
②This is the place that they will never forgrt.
这是他们永远不会忘记的地方。
在①中，从句部分的主谓宾结构是完整的，因而主句中的“place”充当了从句的地点状语，所以使用了关系副词where；在②中从句中没有宾语，因而主句中的“place” 充当了从句的宾语，所以使用了关系代词that。
注意定语从句中有一类非限制性定语从句。非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开，例如：
This is the house which we bought last month. 这是我们上个月买的那幢房子。（限制性）
The house, which we bought last month, is very nice.这幢房子很漂亮，是我们上个月买的。（非限制性）
2) 当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的，例如：
My house, which I bought last year, has got a lovely garden. 我去年买的的那幢房子带着个漂亮的花园。
3) 非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数，例如：
He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思，这使我心烦。
Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽，这就叫做蒸发。
说明：关系代词that和关系副词why不能引导非限制性定语从句。
状语从句
状语从句的种类最多，知识点比较零散，归纳之后有以下几种：
时间状语从句
引导词：when, as, while, as soon as, while, before, after, since, till, until, the minute, the moment, the second, every time, the day， the instant, immediately , directly, no sooner … than,hardly …when, scarcely … when
例：

方式状语从句
引导词：as, as if, how, the way

Sometimes we teach our children the way our parents have taught us.
应当注意的知识点有：
引导时间状语从句的连词
主要有when, while, as, by the time, before, after, since, till/until, as soon as等。其中when、while和as都可表示"当……时候",但用法有区别:
1) when意为"在……时;当……时",可表示"点时间"或"段时间",从句谓语可以 是终止性动词,也可以是延续性动词。例如: When I got home, he was having supper.
2) as意为"边……边……"或"与……同时",重在表示两个动作同时发生、伴随进行。as从句是终止性动词时,主句通常也必须是终止性动词。例如: They sang as they danced.
3) while只可表示"段时间",从句谓语只限于延续性动词。例如: While I was sleeping, my father came in.
引导原因状语从句的连词
原因状语从句一般由because, since, as, for引导. 注意as, because, since 和for的区别:
1) 如果原因是构成句子的最主要部分, 一般用because。because引导的从句一般不放在句子的开头。例如: I missed the train because I got up late.
注:对于以why开头的问句, 一般只能用because引导的从句来回答。
2) 如果原因已为人们所知, 或不如句子的其余部分重要, 就用as或since、since 比as稍微正式一些。as和since引导的从句一般放在句子的开头。例如:
As he was not well,I decided to go there without him.
Since this method doesn't work, let's try another.
3) for表示所说的理由是一种补充说明,因此,for引导的从句可以放在括号里,而
且for引导的从句一般不放在句子的开头。例如: I decided to stop and have lunch, for I was feeling quite hungry.
引导结果状语从句的连词
主要有so/such…that…,so that等。
1) so...that结构在某种情况下可以与enough to和too...to结构相互转换。例如:
She is so short that she can't reach the buttons of the lift.
=She is too short to reach the buttons of the lift.
2)so that也可以引导结果状语从句,意为"结果是;以致于"。例如: They missed the bus so that they were late for class.
注:so that也可引导目的状语从句, 此时可用to或in order to替换, 将其改为简单句。
例如: He got up early so that he could get to school on time.
=He got up early to get to school on time.
=In order to get to school on time,he got up early .
主语从句
主语从句主要有三类：
由连词that引导的主语从句。 例如：That you will win the medal seems unlikely.
你想获得奖牌看起来是不可能的。
用连接代词which或连接副词if, whether 引导的主语从句。 例如：
Which of them escaped from the prison is still a mystery.
他们哪一个是从监狱里逃跑的，仍然是个谜。
When they will come hasn’t been made pubic.
他们什么时候来还不知道。
Whether she is coming or not doesn’t matter too much.
她来不来都无关紧要。
用关系代词（what,whatever,who,whoerver）引导的主语从句。
主语从句可以直接放在主语位置上，也可以用it作形式主语， 而将从句放在句末（尤其是当谓语较短时）。
当what引导的主语从句表示“…的东西”时，一般不用it作形式主语。
错:It is a book what he wants.
对:What he wants is a book. 他想要的是本书。
如果带主语从句的句子是疑问式，则必须用it作形式主语的结构。
例如：Has it been settled who will be sent to carry out the task ?
谁将被派去执行这项任务决定了吗 ？
固定用法：It is +名词+从句；It is +形容词+从句；It is +过去分词+从句；It +不及物动词+从句(当“及物动词 + 宾语”较短时，也可用这种结构);It +某些固定结构+ 主语从句。
同位语从句
在复合句中用作同位语的从句叫同位语从句。它一般跟在某些名词后面，用以说明该名词表示的具体内容。如： I heard the news that our team had won．我听到了我们队获胜的消息。
可以跟同位语从句的名词通常有news，idea，fact，promise，question，doubt，thought，hope，message，suggestion，words（消息），possibility等。
英语中引导同位语从句的词有连词 that，whether，连接副词 how,when,where等。（注：if,which 不能引导同位语从句。）如：I have no idea when he will be back．我不知道他什么时候回来。
有时同位语从句可以不紧跟在说明的名词后面，而被别的词隔开。如：The thought came to him that maybe the enemy had fled the city． 他突然想起可能敌人已经逃出城了。

这是我教学中总结的，学生们反映还不错，有什么不明白的再问我。
