初中英语几大从句归纳总结
v 宾语从句
一. 定义：宾语从句是指在一个句子中充当宾语的句子
如：He said that he wanted to be a teacher when he grew up.
二. 宾语从句有三种类型：
1.由从属连词that引导的宾语从句表示陈述意义，连词that常可被省略。例如：I hope (that) they will have fun. Mary said that she felt sleepy.
Can’t you see (that) I’m a bird?
注意：(1)当主句的谓语动词是think,believe等时，宾语从句尽管要表示否定意义，却不用否定形式，而将think等动词变为否定形式。如：I don’t think he will come.我认为他不会来。
(2)两个表示陈述意义的宾语从句并列时，有时省去第一个从句的连词that，但第二个从句的连词that一般不可以省略。如：
He told me (that)they could not decide what to do and that they asked my advice.
2.由从属连词if或whether引导的宾语从句表示“是否(有，能，已经……)”等一般疑问句的含义。
例如：I wonder whether (if) he lives here.
3.由连接代词who,whom,whose,what,which和连接副词when,where,how,why等引导的宾语从句表示“谁，谁的，什么，哪(个，些)，何时，何地，怎样，为什么”等等特殊疑问句的意义。除了连接词及被修饰的词提前以外，宾语从句用陈述句语序。
例如：To masked who could give the message to her mother.
Do you know what he said just now? I wondered how old his brother was.
三.宾语从句的时态呼应：“主现则从任，主过则从过，客观真理一般现”
1.当主句是现在时或将来时的时候，宾语从句可以用所需要的任何时态。
2.主句是过去时，宾语从句一般只能用过去时的某种形式;当从句叙述的是客观事实或一般真理时，宾语从句仍然用现在时态。
3.情态动词must一般不用于过去时，但却可以用于主句是过去时的宾语从句中。
四.宾语从句的语序
1 宾语从句的连接词后加陈述语序(主语在前，谓语在后)
如：I want to know if he can come tomorrow
2 当连接词本身又是宾语从句的主语时，后面直接加谓语动词
如：She asked me who had helped him
v 状语从句
英语中,修饰动词、形容词、副词等的句子成分叫状语。
状语的功用：状语说明地点、时间、原因、目的、结果、条件、方向、程度、方式和伴随状况等，根据状语的功能状语从句可分为：时间状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句。
一.时间状语从句：在一个句子中作时间状语的句子。
时间状语的连接词：when(当…时候) while(当…时候) as(当…时候) after(在…以后) before(在…以前) as soon as(一…就) since(自从…到现在) till /until(直到…才) by the time(到…为止)依旧是连接词后加陈述语序。
1. when 当…的时候(一般情况下：主将从现)
I will become a teacher when I grow up
2. while 当…时
He visited a lot of places while he was traveling.
3. as 在…的同时;一边…一边…
He smiled as he stood up.
4. after 在…之后
He left the classroom after he had finished his homework the other day.
5. before 在…之前
Mr. Brown had worked in a bank for a year before he came here.
6. as soon as 一…就…(一般情况下：主将从现)
We began to work as soon as we got there.
I will write to you as soon as I get home.
7. since 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. (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 直到
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。
They walked till /until it was dark.
Xiao Ming didn’t leave home till / until his father came back.
9. by the time 到…为止 (所在句子的主句应用现在或过去完成时)
By the time he gets there , his father has already gone.
By the time I got to school, the class had already began.
用法辨析：1.when, while和as的区别
When 引导的从句的谓语动词可以是延续性的动词，又可以是瞬时动词。并且when有时表示“就在那时”。
例如： When she came in, I stopped eating. 她进来时，我在吃饭。(瞬时动词)
When I lived in the countryside, I used to carry some water for him.
当的住在农村时，我常常为他担水。(延续性的动词)
We were about to leave when he came in. 我们就要离开，就在那时他进来了。
While 引导的从句的谓语动作必须是延续性的，并强调主句和从句的动作同时发生(或者相对应)。并且while有时还可以表示对比。例如：
While my wife was reading the newspaper, I was watching TV.
I like playing football while you like playing basketball.我喜欢踢足球，而你喜欢打篮球。(对比)
As 表示“一边……一边”，as引导的动作是延续性的动作，一般用于主句和从句动作同时发生;as也可以强调“一先一后。
例如： We always sing as we walk. 我们总是边走边唱。(as表示“一边……一边”)
As we was going out, it began to snow. 当我们出门时，开始下雪了。(as强调句中两个动作紧接着先后发生，而不强调开始下雪的特定时间)
as when while都表示主、从句动作同时发生，三者差异如下：
as
表示“一边。。。一边"的意思
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)
3.常用于常见搭配中
while
1、 用于时间较长时
2、 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。
lt 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是点动词.)
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
She thought I was talking about her daughter, while, in fact, I was talking about my daughter.
他以为我在谈她女儿，然而，实际上在谈论我女儿。(表转折，对比，when, as都不能代替它)
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)
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)
2. 由till或until引导的时间状语从句。
till和until一般情况下两者可以互换，但是在强调句型中多用until。并且要注意的是：如果主句中的谓语动词是瞬时动词时，必须用否定形式;如果主句中的谓语动词是延续性动词时，用肯定或否定形式都可以，但表达的意思不同。例如：
I worked until he came back.我工作到他回来为止。
I didn't work until he came back.他回来我这才开始工作。
3. 由since引导的时间状语从句。
since引导的从句的谓语动词可以是延续性的动词，又可以是瞬时动词。一般情况下，从句谓语动词用一般过去时，而主句的谓语动词用现在完成时，表述为：现在完成时+since+一般过去时。但在It is +时间+since从句的句型中，主句多用一般现在时。例如：
It is five months since our boss was in Beijing.我们老板离开北京有五个月了。
知识扩展
1. It is …since 从….以来多长时间了
It is five years since we met last time.
2. It is …+before…(。。。才。。。)
It was a long time before I went to sleep again.
It was an hour before(=until) the police arrived.
二.原因状语从句：在一个句子中作时间状语的句子。
连接词：由连词because, since, as引导, 也可由for, now that 等词引导
1.I didn’t go to school yesterday because I was ill.
2. Since everybody is here, let’s begin our meeting. 既然。。。
3. As you are in poor health, you should not stay up late. 既然。。。
4.I asked her to stay to tea, for I had something to tell her.
.用法辨析：because , since , as , for辨析
1)because语势最强，用来说明人所不知的原因，回答why提出的问题。当原因是显而易见的或已为人们所知，就用as或 since。
I didn’t go, because I was afraid.
Since /As the weather is so bad, we have to delay our journey.
2)由because引导的从句如果放在句末，且前面有逗号，则可以用for来代替。但如果不是说明直接原因，而是多种情况加以推断，就只能用for。
He is absent today, because / for he is ill.
He must be ill, for he is absent today.
三、条件状语从句
连接词：if如果, unless (=if not) 如果不、除非(让步)
1. If it doesn’t rain tomorrow, we will go hiking.
2. I will go to the party unless he goes there too.
3. You will be late unless you leave immediately.
=If you don’t leave immediately, you will be late.
条件状语从句：主将从现.
He will not leave if it isn’t fine tomorrow.
四、目的、结果状语从句
目的状语从句是指在一个句子中充当目的状语的句子。
结果状语从句是指在一个句子中充当结果状语的句子
目的状语从句连接词so that, so…that , in order that 引导。
结果状语从句连接词 so…that, such…that, so much/many…that引导。
1. so…that 如此…以至于
He always studied so hard that he made great progress.
2. so that 以至于, 以便于
I’ll run slowly so that you can catch up with me. (目的)
I opened the window so that fresh air might come in. (目的)
3. such…that 如此…以至
It’s such nice weather that all of us want to go to the park.
4. in order that=so that 为了
We shall let you know the details soon in order that you can/may make your arrangements.
5.比较：so和 such
其规律由so与such的不同词性决定。such 是形容词，修饰名词或名词词组，so 是副词，只能修饰形容词或副词。 so 还可与表示数量的形容词many, few, much, little连用，形成固定搭配。
so nice a flowersuch a nice flower
so many / few flowerssuch nice flowers
so many peoplesuch a lot of people
( so many 已成固定搭配，a lot of 虽相当于 many，但 a lot of 为名词性的，只能用such搭配。)
难点
so+形容词或副词 so+形+a(an)+单数可数名词
so +many /few+复数可数名词
so +much/ little+不可数名词
so…that与such…that皆可引导目的地状语从句和结果状语从句。
The boy is so young that he can’t go to school.
He is such a young boy that he can’t go to school
so +adj/adv.+ that， such +n.+ that 以上两种句型都表示结果
so为副词,后接形容词，副词原型，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.
such为形容词, 后只能接名词。这名词既可以地可数的，也可以是不可数的。如果这名词是可数的,则必须在名词前加不定冠词a(an). 常见的形式是:such a (beautiful)garden, such(nice)people.
五、让步状语从句 让步状语从句是指在句子中作让步的状语的句子
连接词： though, although.，whether…or not
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不能作并列连词，although不能作副词，放在词尾表示强调时要用even though.
1、Even though I didn’t under a word, I kept smiling. 尽管
【典型例题】
1) ___she is young, she knows quite a lot.
A. WhenB. HoweverC. AlthoughD. Unless
2)ever if, even though. 即使
We’ll make a trip even though the weather is bad.
3) whether…or not 不管……都
Whether you believe it or not, it is true.
no matter 从句
结构："no matter +特殊疑问词疑问词+陈述语序" 或"特殊疑问词+后缀ever+陈述语序"
No matter what happened, he would not mind.
Whatever happened, he would not mind.
替换：no matter what = whatever no matter who = whoever
no matter when = whenever no matter where = wherever
no matter which = whichever no matter how = however
注意：no matter 不能引导主语从句和宾语从句。
(错)No matter what you say is not useful now.
(对)Whatever you say is not useful now. 你现在说什么也没用了。
(Whatever you say是主语从句)
(错)Prisoners have to eat no matter what they’re given,
(对)Prisoners have to eat whatever they’re given. 囚犯们只能给什么吃什么
v 定语从句
定语是指在句子中用来修饰名词、代词的成分
定语从句是指在一个句子中作定语的句子，定语从句要放在所修饰的词后
如：I have met the doctor who is in the No.1 hospital.
定语从句的连接词：
1.连接代词：who、which、whom、whose、that
2.连接副词：when、where、why
选用连接词的关键是看先行词(定语从句所修饰的名词或代词)
一、连接代词的选用：
1.who 指人，先行词为人,在从句中做主语
Yesterday I helped an old man who lost his way.
2. whom 指人，先行词为人,在定语从句中充当宾语，常可省略。
Mr. Liu is the person (whom) you talked about on the bus.
注意：关系代词whom在口语和非正式语体中常用who代替，可省略。
3.which 指物，先行词为物,在定语从句中做主语或者宾语，做宾语时可省略
This is the pen (which) he bought yesterday.
4. that 指人时，相当于who或者whom;指物时，相当于which。在定语从句中做主语或者宾语，做宾语时可省略。
The number of the people that/who come to visit the city each year rises one million.
Where is the man that/whom I saw this morning?
5. whose 通常指人，也可指物，在定语从句中做定语,译成 "...的"
He has a friend whose father is a doctor.
指物时，常用以下结构来代替
Do you like the book whose cover is yellow? = Do you like the book the color of which is yellow?
介词+连接代词引导的定语从句连接代词在定语从句中做介词宾语时,从句常由介词+连接代词引导
The school (that/which) he once studied in is very famous.
The school in which he once studied is very famous.
注意：1. 含有介词的动词短语一般不拆开使用，如：look for, look after, take care of等
This is the watch which/that I am looking for. (T)
This is the watch for which I am looking. (F)
2. 若介词放在连接代词前，连接代词指人时用whom，不可用who或者that;指物时用which，不能用that;连接代词是所有格时用whose
The man with whom you talked is my friend.
The plane in which we flew to Canada is very comfortable. (T)
3. “介词+连接代词”前可有some, any, none, both, all, neither, most, each, few等代词或者数词
He loved his parents deeply, both of whom are very kind to him.
In the basket there are quite many apples, some of which have gone bad.
There are forty students in our class in all, most of whom are from big cities
二、连接副词的选用：
1. when指时间，在定语从句中做时间状语
I still remember the day when I first came to the school.
2. where指地点，在定语从句中做地点状语
Shanghai is the city where I was born.
3. why指原因，在定语从句中做原因状语
Please tell me the reason why you missed the plane.
注意：关系副词引导的从句可以由“介词+关系代词”引导的从句替换
The reason why/ for which he refused the invitation is not clear,
From the year when/in which he was going to school he began to know what he wanted when he grew up.
Great changes have taken place in the city in which./where I was born.
三、判断关系代词和关系副词的方法: 准确判断先行词在定语从句中的成分(主、谓、宾、定、状)
例1. Is this the museum ___ you visited a few days ago?
A. whereB. that C. on which D. the one
例2. Is this the museum ____ the exhibition was held?
A. whereB. that C. on whichD. the one
关系词的选择依据在从句中所做的成分，先行词在从句中做主、定、宾语时，选择关系代词 (who, whom, that, which, whose);
先行词在从句中做状语时，应选择关系副词 ( where 地点状语，when 时间状语，why 原因状语)
四、介词+连接词用法说明
1)介词后面的关系词不能省略。
2)that前不能有介词。
3)某些在从句中充当时间，地点或原因状语的"介词+关系词"结构可以同关系副词when ,where和why 互换
如：This is the house in which I lived two years ago.This is the house where I lived two years ago.
Do you remember the day on which you joined our club?Do you remember the day when you joined our club?
This is the reason why he came late. This is the reason for which he came late.
五.限制性定语从句和非限制性定语从句
限制性定语从句举例：
china is a country which has a long history.
非限制性定语从句举例：
his mother, who loves him very much, is strict with him.
要注意区分以下几个句子的不同
his brother who is now a doctor always encourages him to go to college.
他那当医生的哥哥常鼓励他要考上大学。(他还有其他的哥哥)
his brother, who is now a doctor, always encourages him to go to college.
他的哥哥是当医生的，常鼓励他要考上大学。(他只有一个哥哥)
关系代词as和which 引导的定语从句
as和which引导非限制性定语从句，有相同之处也有不同之处。具体情况是：
1.as和which都可以在定语从句中做主语或者宾语，代表前面整个句子。
(1) he married her, as/which was natural.
(2) he was honest, as/which we can see.
2. as引导非限制性定语从句，可放在主句之前，或者主句之后，甚至可以切割一个主句;
which引导的非限制性定语从句只能放在主句之后。
另外，as有“正如……，正像……”的意思
as is known to all, china is a developing country.
he is from the south, as we can see from his accent.
john, as you know, is a famous writer.
he has been to paris more than several times, which i don't believe.
注意：当主句和从句存在逻辑上的因果关系时，常用which
tom was always late for school, which made his teacher angry.
3. 当先行次受such, the same修饰时，常用as
i have never heard such a story as he tells.
he is not such a fool as he looks.
this is the same book as i lost last week.
注意：当先行次由the same修饰时，偶尔也用that引导定语从句，但是和由as 所引导的定语从句意思不同
she wore the same dress that she wore at mary's wedding.
她穿着她在mary婚礼上穿过的一条裙子。
she wore the same dress as her young sister wore.
她穿着和她妹妹所穿的一样的裙子。
以the way为先行词的定语从句通常由in which, that引导，而且通常可以省略。
the way in which/ that/./ he answered the question was surprising.
but 有时也可以做关系词引导定语从句
there are very few but understand his idea. ( but= who don't )
定语从句只能用that的几种情况
1.当先行词是anything, everything, nothing (something 除外), few, all, none, little, some等代词时，或者是由every, any, all, some, no, little, few, much等修饰时
Have you taken down everything that Mr. Li has said?
All that can be done has been done.
There is little that I can do for you.
注意：当先行词指人时，偶尔也可以用who
Any man that/who has a sense of duty won’t do such a thing.
2. 当先行词被序数词修饰
The first place that they visited in London was the Big Ben.
3. 当先行词被形容词最高级修饰时
This is the best film that I have seen.
4. 当形容词被the very, the only 修饰时
This is the very good dictionary that I want to buy,
当先行词指人时，偶尔也可以用who
Wang Hua is the only person in our school who will attend the meeting?
5. 当先行词前面有who, which等疑问代词时
Who is the man that is standing there?
6. 当先行词既有人，也有动物或者物体时
Can you remember the scientist and his theory that we have learned?
初中英语学习方法总结
一、日常学习法
1.制定长远目标，明确每节课的学习任务
根据不同学习阶段及自身能力确立一个“跳一跳才能够得着”的长远目标。有了目标就有了学习动力，有了责任感、紧迫感及努力方向。另外还要学会根据不同课型确定每节课的认知小目标，这样一开始上课，就会受到目标的激励，使大脑处于兴奋状态，才能定向注意，专心致志地去主动学习，提高学习效率。
2.争取课内外各种机会多练习英语
语言不是教会的，而是在使用中学会的。交际能力只能在交际中得到最有效的培养。一个优秀的语言学习者应具有强烈的语言交际的欲望，应力争语言训练的各种机会。应不怕因犯语言错误而被别人讥笑。
3.课前预习，有备而听
预习是个人独立的阅读和思考。它可以培养学习者快速阅读抓主旨大意、抓主要信息、依据上下文猜测词义的能力，也可以培养分析综合及归纳概括、自己发现问题及解决问题等能力。预习也像“火力侦察”，可发现疑难引起思考，一方面可促使学习者自己查阅有关资料，查阅字典，另一方面可减少听课的盲目性，增强听课效果。
4.专心上课，有心识记
上课是学生学习的主渠道，而学好英语的关键是尽一切努力将所学的东西记住，需要时能运用自如。因此，上课时应高度集中注意力.尽量做到五到，即心到、眼到、耳到、口到、手到。应培养瞬间记忆能力，强化“有意注意”，争取就在课内有目标、有意识地去识记该课的生词、短语、句型、重点句子。当接触到该记忆的内容时，应通过眼看、耳听、口念，将其迅速输入到记忆中枢，然后再复现出它的形象。在复现时快速用手指在桌上划出这个单词，或一个长句中最难记的或最重要的单饲，强迫自己在课内就能记住这节课最重要的东西。这样，使自己真正有着“这节课确实学到不少东西”的踏实感、成功感，进而激发动机，提高兴越，更有信心地去继续今后的学习。
5.勤记笔记，巩固记忆
课内扼要记笔记可以帮助集中注意力，理顺思路，增进记忆，锻炼分析归纳、综合概括以及快速反应能力。俗话说“好记性不如烂笔头”。笔记也为日后复习提供一个复习记忆纲要。要学好英语离不开泛读。进行课外阅读时也应扼要记些笔记，做些索引、摘录等，这对加深理解、巩固、积累知识，培养学习能力大有好处。
6.及时、经常、科学地复习，减少遗忘
复习是学习之母。要解决困扰学习者最大的知识遗忘问题，只有靠科学的复习。“艾宾浩斯遗忘曲线”揭示遗忘规律是先快后慢，先多后少。因而从时间安排上讲，复习既要及时又要经常。不仅在当天，而且在第二天、一周后、一月后以及就在你需要用它之前或者在考试前都应安排复习。从复习方法上讲.可采用强化复习(过渡/超额复习)、分散复习、集中复习，把新旧知识有机联系起来，按知识内在规律进行综合归类等复习方法，做到温故而知新，而不是简单机械复现，从而更牢固地掌握知识。
