1. 英语语法定语从句
单纯的说定语从句的话
只要明确了什么是定语
而什么是句子便可以了
二者综合成为顾名思义的定语从句
值得一提的是
定语从句基本上充当的是名词或形容词性
自然在意义上也属于名词或形容词
祝学业有成！
2. 初中英语从句知识点总结

3. 初中英语各种从句的总结
简单点说就是看谓动词，比如look，后面不能带to，那look后的成分就是表语；比如happy，后面可以带to，后面的成分就是宾语。我这个是大众总结，有特例的，仅供参考，便于记忆
4. 初中英语定语从句讲解
定语从句即用句子来做定语，被修饰或被限制的词称作先行词，例如版
1.I don't know the girl who is talking there.
2.I don't know the girl who you met just now.
3.Give me the book that you read just now.
4.Give me the book ,which you read just now.
5.Give me the pen that you write with.
6.Give me the pen with which you write .
仔细看句子中的book 和pen就是先权行词，他们后面的who that which 就是引导定语从句的关系代词，当先行词是人用who,先行词是物用that,先行词后出现介词或逗号用which.
这是一种捷径，细节问题找本语法书慢慢学。
5. 初中英语所有学到的从句总结
一楼的等于没说！补充点：初中英语语法总结
( 动词的时态) 11.1 一般现在时的用法 1） 经常性或习惯性的动作，常与表示频度的时间状语连用。时间状语： every…, sometimes, at…, on Sunday。例如： I leave home for school at 7 every morning. 每天早上我七点离开家。 2） 客观真理，客观存在，科学事实。例如： The earth moves around the sun. 地球绕太阳转动。 Shanghai lies in the east of China. 上海位于中国东部。 3） 表示格言或警句。例如： Pride goes before a fall. 骄者必败。 注意：此用法如果出现在宾语从句中，即使主句是过去时，从句谓语也要用一般现在时。例：Columbus proved that the earth is round. 哥伦布证实了地球是圆的。 4） 现在时刻的状态、能力、性格、个性。例如： I don't want so much. 我不要那么多。 Ann writes good English but does not speak well. 安英语写得不错，讲的可不行。 比较：Now I put the sugar in the cup. 把糖放入杯子。 I am doing my homework now. 我正在做功课。 第一句用一般现在时，用于操作演示或指导说明的示范性动作，表示言行的瞬间动作。第二句中的now是进行时的标志，表示正在进行的动作的客观状况，所以后句用一般现在时。 11.2 一般过去时的用法 1）在确定的过去时间里所发生的动作或存在的状态。例如：时间状语有：yesterday, last week, an hour ago, the other day, in 1982等。例如： Where did you go just now? 刚才你上哪儿去了？ 2）表示在过去一段时间内，经常性或习惯性的动作。例如： When I was a child, I often played football in the street. 我是个孩子的时候，常在马路上踢足球。 Whenever the Browns went ring their visit, they were given a warm welcome. 那时，布朗一家无论什么时候去，都受到热烈欢迎。 3）句型：It is time for sb. to do sth "到……时间了" "该……了"。例如：It is time for you to go to bed. 你该睡觉了。 It is time that sb. did sth. "时间已迟了" "早该……了" ，例如It is time you went to bed. 你早该睡觉了。 would （had） rather sb. did sth. 表示'宁愿某人做某事'。例如：I'd rather you came tomorrow.还是明天来吧。 4） wish, wonder, think, hope 等用过去时，作试探性的询问、请求、建议等，而一般过去时表示的动作或状态都已成为过去，现已不复存在。例如：I thought you might have some. 我以为你想要一些。 比较：Christine was an invalid all her life.（含义：她已不在人间。） Christine has been an invalid all her life.（含义：她现在还活着） Mrs. Darby lived in Kentucky for seven years. （含义：达比太太已不再住在肯塔基州。） Mrs. Darby has lived in Kentucky for seven years. （含义：现在还住在肯塔基州，有可能指刚离去） 注意： 用过去时表示现在，表示委婉语气。 1）动词want, hope, wonder, think, intend 等。例如： Did you want anything else? 您还要些什么吗？ I wondered if you could help me. 能不能帮我一下。 2）情态动词 could, would。例如： Could you lend me your bike? 你的自行车，能借用一些吗？ 11.3 used to / be used to used to + do："过去常常"表示过去习惯性的动作或状态，但如今已不存在。例如： Mother used not to be so forgetful. 老妈过去没那么健忘。 Scarf used to take a walk. 斯卡夫过去常常散步。 be used to + doing：对……已感到习惯，或"习惯于"，to是介词，后需加名词或动名词。例如： He is used to a vegetarian diet. Scarf is used to taking a walk. 斯卡夫现在已习惯于散步了。 典型例题 ---- Your phone number again? I ___ quite catch it. ---- It's 69568442. A. didn't B. couldn't C. don't D. can't 答案A. 本句虽没有明确的时间状语，但从语意上看出，在听的时候没有听懂这个动作发生在过去，因此应用过去时。 11.4 一般将来时 1） shall用于第一人称，常被will 所代替。will 在陈述句中用于各人称，在征求意见时常用于第二人称。例如： Which paragraph shall I read first？ 我先读哪一段呢？ Will you be at home at seven this evening? 今晚七点回家好吗？ 2） be going to +不定式，表示将来。 a. 主语的意图，即将做某事。例如：What are you going to do tomorrow? 明天打算作什么呢？ b. 计划，安排要发生的事。例如：The play is going to be proced next month。这出戏下月开播。 c. 有迹象要发生的事。例如：Look at the dark clouds, there is going to be a storm. 看那乌云，快要下雨了。 3） be +不定式表将来，按计划或正式安排将发生的事。例如： We are to discuss the report next Saturday.我们下星期六讨论这份报告。 4） be about to +不定式，意为马上做某事。例如： He is about to leave for Beijing. 他马上要去北京。 注意：be about to do 不能与tomorrow, next week 等表示明确将来时的时间状语连用。 11.5 be going to / will 用于条件句时，be going to表将来,will表意愿。例如： If you are going to make a journey, you'd better get ready for it as soon as possible.

6. 初中有关定语从句的语法
初中定语从句详解。 定语从句是一种形容词的关系从句。它由关系代词或关系副词引导（1）。初中英语中的定语从句仅限于限制性定于从句，但对初中生来说，定语从句既是一个重点，也是一个难点。【关键词】定语从句 先行词 关系代词 关系副词
一、英语中的定语从句与汉语中的定语位置不同。
在复合句中，修饰某一名词或代词的从句叫做定语从句。英语中的定语从句始终要放在被修饰的词之后，而汉语中的定语则放在被修饰词之前。如：
The man who / that I saw at the school gate yesterday is my English teacher.
先行词 定语从句
昨天我在校门口看见的那个人是我的英语老师。
二、英语从句中的句型结构比较复杂，有先行词、关系代词或关系副词。被定语从句修饰的词叫先行词，引导定语从句的关联词有关系代词或关系副词。限制性关系分句和它的先行项的所指意义有着不可分割的联系（2）。关系代词或关系副词放在先行词和定语从句之间起纽带作用，关系代词或关系副词在定语从句中要充当一个成分。关系代词在句中可作主语、宾语或定语，关系副词在句中作状语。如：
I am waiting for the boy who /that is wearing a red coat. （主语）
先行词 关系代词
我正在等穿着红色外套的那个男孩。
The dictionary that / which my sister gave me last Sunday is very expensive.(宾语)
先行词 关系代词
我姐姐上周星期天给我的那本字典很贵。
The woman is his mother whose name is Linda Brown. (定语)
先行词 关系代词
那个是他的母亲，名叫琳达
7. 初中英语：定语从句的用法
1.what不能引导定语从句.
2.关系词的分析须考虑它在定语从句中的成分。
一.指人的关系代词有who、whose、whom、that. 试分析：
The old man who/whom /that we visited yesterday is a famous artist.
Miss Wang is taking care of the child whose parents have gone to Beijing .
The man with whom my father shook hands just now is our headmaster. （=The man who/whom that my father shook hands with just now is our headmaster.）注：
A．指人时有时只用who不宜用that。
1．先行词为one、ones或anyone
（1）The comrade I want to learn from is the one who studies hard and works hard.
（2）Anyone who breaks the law should be punished.
2．先行词为these时
These who are going to Beijing are the best students of our school.
3．在there be 开头的句子中
There is a student who wants to see you.
4．一个句子中带有两个定语从句，其中一个定语从句的关系代词是that，另一个宜用who，以免重复。
The student that won the first prize is the monitor who works hards.
5．在非限制性定语从句中
A。I met a friend of mine in the street, who had just come from Japan.
B．主句以who开头的句子中,只用that,不用who。
二．指物的关系代词有which、whose(=of which)、that. 试分析：
1. I like the books which / that were written by Lu Xun.
2. The desks (which/that) we made last year were very good.
3. This is the house in which we lived last year. (= This is the house which /that we lived in last year.)
4. I live in the room whose windows face south. (= I live in the room ,the windows of which face south.)
注：
A. 介词如果位于作为其宾语的关系代词之前时，只能用whom、 which不能用who或that.
(1). The girl about whom they were talking is our monitor.
(2). The book in which there are many interesting things was written by Li Ming.
B. 部分短语动词中的介词不可与动词拆开，在定语从句中其介词不可前置，只能放在其动词之后。
Is this the book which she is looking for?
The old man who/whom they are waiting for is Professor Li.
The child who/whom she is looking after is Wang Ping’s son.
C．指物时，下列情况下只能用that ，不宜用which。
（1）先行词为不定代词，如All、much、anything、everything、nothing、something、none、the one等。
We are willing to do anything that is good to the people.
I have told them all (that) I know.
All that can be done has been done.
（2）先行词是序数词或被序数词、修饰时。

There are sheep and men that can be seen on the hill.
（5）如果先行词被the only、the very、the last、the same、any、 few 、little、no、 all 、one of、 just修饰时。
This is the only book that can be lent to you.
（6）当主句是以which开头的特殊问句时，关系代词只用that。
Which is the dictionary that he used yesterday ?
D．只物时，下列情况下只能用which，不宜用that。
（1）关系代词放在介词之后
This is the factory in which we once worked.
（2）非限制性定语从句中
This is the book, which is written by Lu Xun.
（3）that，Those作主语时
Those which are on the desk are English books.
E．先行词前有such、the same、 as时, 关系代词用as，不用that, 但the same…as…表示同样的, the same…that…表示同一的

Such people as you refer to are rare nowadays.
三．比较When/which、where /which、why.
which I still never forget.
This is the day when I joined the party.
which he spent reading the books.
where I found the book.
which makes machines.
This is the place which we once visited.
which I will never forget.
which I am looking for.
限制性定语从句与非限制性定语从句的区别：
限制性定语从句
非限制性定语从句
All the students who study hard have passed.学习努力的学生都考试及格了。(只有努力的及格了，不努力的没及格。) All the students ,who study hard have passed.所有的学生都及格了，他们学习努力。（没有人不及格，这些学生都很努力。）
从句是先行词不可缺少的定语（如去掉，主句意思就不完整或不正确。）从句是对先行词的附加说明（如去掉，主句意思仍清楚，不受影响。）与主句关系密切，不用逗号与主句关系不十分密切，用逗号与主句隔开译为汉语时，从句译在先行词前，与先行词用“的”连接译为汉语时，从句放在主句后面关系代词that可以代替who、whom(指人)、which(指物) 关系代词不用that,只用who、whom(指人)、which(指物) 关系代词代替宾语时可以省略关系代词不能省略关系代词as和which
先研究下面两个例句：
○1.This elephant is like a snake, as /which everybody can see. =As everybody can see, this elephant is like a snake. 任何人都看得出来，这头象像条蛇。
○2.Tom didn’t pass the physics exam, which made his parents very angry. Tom物理考试不及格，这使得他父亲很生气。
这两个例句中，as和which所代表的都是整个主句所表示的内容。但有两点不同之处：
1．在形式上as引导的非限制性定语从句可位于主句的后面，也可位于主句的前面；而which引导的非限制性定语从句只能位于主句的后面，不能位于主句的前面。
2．在意义上，as引导的定语从句和主句的关系一般为一致关系，常译为“正如……”，“就像……”，而which引导的定语从句和主句的关系是因果关系，或which引导的定语从句是对主句的评论。因此，在意思通顺的情况下，which可代替as，而as许多时候不能代替which，如句○2。再如：
1．He was late again, as / which we had expected. =As we had expected, he was late again. 正如我们所料，他又迟到了。/他又迟到了这是我们早就料到的。
2． The street hasn’t been cleared for weeks, which makes it very dirty. 街道好多星期没有打扫了，因此整条街很脏。（不用as）
3．The young man cheated his friend of much money, which was disgraceful. 那年轻人诈骗了他朋友许多钱财，这是不光彩的。（不用as）
4．He takes exercise everyday, which has done a lot of good to his health. 他每天运动，这对他的身体很有好处。（不用as）
5．As has already been pointed out, English is rather difficult for a foreigner. 正如已经指出的那样，英语对于初学者说，是相当难学的。在such…as…、the same…as…、 as…、 as many…/much as…等结构中,as不能用which代替。如：
1.Such books as this are too difficult for beginners. 这样的书对于初学的人来说是太难了。
=Books such as this are …
=Books like this are …
2.I live in the same building as he (does). 我和他住再同一座大楼里。
3.He knows as many people as are present at the meeting. 他认识所有到会的人。
4.That day we all got up early as usual. 那天我们和平时一样，都起得很早。
“One of the +复数名词”后面定语从句中谓语单复数情况
这一结构后面的定语从句的谓语动词通常用复数形式，跟定语从句所靠近的那个复数名词在数上保持一致。如：
1． That is one of the books that are required for study at school.
2． This is one of the most wonderful novels that have been published since 1990.
3． She is one of the few persons who know Spanish .
4． This is one of the most famous plays that were written in the thirties,
如果one of +复数名词这一结构前面带有the only、the very之类的限定语，后面定语从句的谓语动词则要用单数形式，这是因为定语从句在意义上修饰的是而不是那个复数名词。如：
1.He is the only one of the teachers who knows French in our school.( 修饰the only one)
He is one of the teachers who know French in our school.( 修饰the teachers)
2.This is the only one of the rooms that is free now. (修饰the only one)
This is one of the rooms that are free now. (修饰rooms)
as与which引导的定语从句
两者均可引导非限制性定语从句，有时可以互换，但下列情况多用as。
1. 关系代词引导的定语从句居句首时。 As we all know, the earth is round.
2. 当与such或the same连用时，一般用as。 Such books as you tell me are interesting. I have the same plan as you.
3. 当从句和主句语义一致时，用as，反之则用which。 She has married again, as was expected. She has married again, which was unexpected.
4. as在从句中作主语时，后面常接行为动词的被动语态，如be known，be said，be reported等，如从句中行为动词是主动语态，一般要用which作主语。
She has been late again, as was expected.
Tom has made great progress, which made us happy.
8. 初中英语定语从句
定语从句：英语中，在复合句中作定语，修饰主句中的某名词或代词的从句。
先行词：被定语从句所修饰的词，通常放在定语从句之前。
引导词：引导定语从句的词（也叫关联词）
关系代词：如that, which，who,whom,whose等
关系副词:如when, where, why等）。
引导词通常位于先行词和定语从句之间，它既起联系作用，又充当从句中的某个句子成分。
其间主要区别：
一。that与which的用法区别
两者都可指物，常可互换。其区别主要在于：
1. 引导非限制性定语从句时，通常要用which：
The current, which is very rapid, makes the river dangerous. 水流湍急，使这条河很危险。
He has to work on Sundays, which he doesn’t like. 他得在星期天工作，他是不喜欢这样的。
The London team, which played so well last season, has done badly this season. 伦敦队上一个季度打得很好，这个季度却打得很差。
2. 直接放在介词后作宾语时，通常要用which：
She may be late, in which case we ought to wait for her. 她可能晚到，那样我们就要等等她。
The documents for which they were searching have been recovered. 他们找寻的文件已找到了。
This morning some port wine came, for which I have to thank you. 今天早上送来一些波尔图葡萄酒，为此我得向你道谢。
注：有时“介词+which”引导的定语从句可以转换成“介词+which+不定式”结构：
He had only the long nights in which he could study. =He had only the long nights in which to study. 他只有漫漫长夜可用来学习。
He had a couple of revolvers with which he could defend himself.= He had a couple of revolvers with which to defend himself. 他只有一两把手枪用来自卫。
3. 当先行词是下列不定代词或被它们修饰时much, little, none, all, few, every(thing), any(thing), no(thing) 等时，通常用that：
All that she lacked was training. 她缺的只是训练。
Have you everything that you need? 你需要的东西都有了吗?
The sleeping man’s subconscious mind retained everything that was said around him. 这位酣睡的人头脑的下意识能记住他周围的人说的话。
She would never do anything that was not approved of by her parents. 她父母不赞同的事她绝不会做。
4. 当先行词有the very, the only, the same 等修饰时，通常用that：
This is the only example that I know. 我知道的例子只有这一个。
Those are the very words that he used. 那是他的原话。
5. 当先行词有形容词最高级或序数词(包括last, next等)等修饰时，通常用that：
This is the best dictionary that I’ve ever used. 这是我用过的最好的词典。
The first thing that you should do is to work out a plan. 你应该做的第一件事是订个计划。
6. 当关系代词在定语从句中用作表语时，通常用that：
China is not the country (that) it was. 中国已不是过去的中国了。
7. 当先行词是一个既指人又指物的并列词组时，通常用that：
They talked about the persons and things that most impressed them. 他们谈论了使他们印象最深的人和事。
8. 当要避免重复时：
Which is the course that we are to take? 我们选哪门课程？
二。that与who的用法区别
1. 两者均可指人，有时可互换（包括当先行词为 all, anyone, someone等，同时也包括先行词受the only等的修饰时）：
All that [who] heard him were delighted. 所有听了他讲话的人都很高兴。
He is the only one among us that [who] knows Russian.他是我们中间唯一懂俄语的人。
Anyone who [that] is over sixteen is allowed in. 任何超过十六岁的人都允许进去。
It is impolite to turn your back on someone who [that] is speaking to you. 人家跟你说话，你把背朝人是不礼貌的。
2. 但是在下列情况，通常要用 that：
①当先行词是一个既指人又指物的并列词组时：
I made a speech on the men and things that I had seen abroad. 我就我在国外所见到的人和事作了报告。
②当先行词是who时(为避免重复)：
Who was it that won the World Cup in 1982? 谁赢得了1982年的世界杯？
③当关系代词在定语从句中作表语时(可省略)：
Tom is not the boy (that) he was. 汤姆这孩子已不是以前那个样子了。
3. 但是在下列情况，通常要用 who：(www.yygrammar.com)
当先行词为 those 且指人时，英语习惯上要用 who 来引导定语从句。如：
Those who do not wish to go need not go. 不愿去的人不需要去。
Those who couldn’t walk were carried on stretchers. 那些不能走的人都用担架抬着。
It is said that those who eat the most are the least healthy. 据说吃得最多的人身体最差。
Only those who had booked in advance were allowed in. 只有那些预先订票的人可以进去。
The plan was supported by those who wished to listen to more good English. 这计划受到想多听好英语的人的支持。
Let us spend a few moments in silence so that / in order that we remember those who died to preserve our freedom. 让我们默哀片刻，以缅怀那些为维护我们的自由而牺牲了的人们。
注：偶尔也可见到在 who 之后用 that 引导定语从句的用例，但相当少见。如：
The danger is that people who pay their bills on time will be lumped in with those that don’t. 危险的是那些及时付账的人将会同那些不及时付账的人混在一起。（摘自《朗文当代英语辞典》2003年第4版）
希望你学业有成！
