1.主要包括主语从句,宾语从句,表语从句和同位语从句.一般由that 引起,也可由who, what, when, why, which, whom, whether, how 引起.2.主语从句很多情况下都可以放到句子后面,而用代词it作形式上的主语.:

3.形式宾语

4.由名词性关系代词whatever, whoever, whichever 等引起的宾语从句

5.whether and if 都能引导从句, 但用法有所不同.当主语从句直接位于句首时,应用whether,而不用if.Whether 后能直接or not, 但if 不能.Whether he will come or not is not known.6.在名词reason后的表语从句必须用that引导, 不可误用 because.The reason why he is often late for class is that he has the bad habit of getting up late in the morning.二: 定语从句

1.引导定语从句的关系词有who, whom, whose, that, when, where, why and which.在非限制定语从句中, 只可用which, who, whose, where , when., 如果指代前面整个句子, 多用which.2.当引导定语从句的先行词前有all, any, no, little, much, very first 等词, 或先行词前为形容词最高级所修饰时,或先行词为all, anything, nothing, something, everything 时,从句的引导词只能用that.3.as 可做引导词引导定语从句, 多和such, the same 连用.As 引导的定语从句也可修饰整个句子, 既可放在先行词后,也可放在句子开头.4.介词+which/whom/whose从句

5.代/名+介词+which 从句

四、定语从句的分类

根据定语从句与先行词的关系，定语从句可分为限制性定语从句及非限制性定语从句。限制性定语从句紧跟先行词，主句与从句不用逗号分开，从句不可省去，非限制性定语从句主句与从句之间有逗号分开，起补充说明作用，如省去，意思仍完整。

五、关系代词的用法

1.that 既可以用于指人，也可以用于指物。在从句中作主语或宾语，作主语时不可省略，作宾语可省略。例如：

Mary likes music that is quiet and gentle.玛丽喜欢轻柔的音乐。(that作主语)

2.which用于指物，在句中作主语或宾语，作主语不可省略，作宾语可省略。例如：

The building which stands near the train station is a supermarket.位于火车站附近的那座大楼是一家超市。(作主语)

The film(which)we saw last night was wonderful.我们昨天晚上看的那部电影很好看。(作宾语)

3.who，whom用于指人，who 用作主语，whom用作宾语。在口语中，有时可用who代替whom，也可省略。例如：

The girl who often helps me with my English is from England.经常在英语方面帮助我的那个女孩是英国人。(作主语)

Who is the teacher(whom)Li Ming is talking to? 正在与李明谈话的老师是谁?(作宾语)

注意：(1)当定语从句中含有介词，介词放在句末时，who，that，which可省略，但介词在关系代词前时，只能用“介词+which/whom”结构。例如：

This is the house in which we lived last year.这是我们去年居住的房子。

Please tell me from whom you borrowed the English novel.请告诉我你从谁那借的这本英文小说。

(2)含有介词的固定动词词组中，介词不可前置，只能放在原来的位置上。例如：

(3)that 作介词的宾语时，介词不能放它的前面，只能放在从句中动词的后面。例如：

The city that she lives in is very far away.她居住的城市非常远。

(4)关系词只能用that的情况：

a.先行词被序数词或形容词最高级所修饰，或本身是序数词、基数词、形容词最高级时，只能用that，而不用which.例如：

e.以who或which引导的特殊疑问句，为避免重复，只能用that.例如：

Who is the girl that is crying? 正在哭泣的那个女孩是谁?

f.主句是there be 结构，修饰主语的定语从句用that，而不用which.例如：

There is a book on the desk that belongs to Tom.桌子上那本书是汤姆的。

(5)关系词只能用which，而不用that 的情况：

a.先行词为that，those时，用which，而不用that.例如：

第三篇：初中定语从句

定语从句

定语从句是在主从复合句中修饰某个名词或代词句子，它在句中作定语。被修饰的名词或代词叫先行词，连接先行词和定语从句的词叫引导词(也叫关系词)。如 I know the girl who is sitting under the tree.我认识那个正坐在树下的女孩。↓ ↘引导词 ↓

先行词 从句(定语从句)This is the most interesting book that he has ever read.这是他所读过的书中最有趣的一本。↓ ↘引导词 ↓

先行词 从句(定语从句)考点1：先行词是人时引导词的选用

(1).先行词是人，引导词后紧跟动词时用who或that.如：

Here comes the man who(that)wants to see you.想见你的那个人来了。(先行词是the man, 引导词后紧跟动词wants, 故引导词用who / that)(2).先行词是人，引导词后紧跟的不是动词时要用who, whom, that.如： This is the person whom(who, that)you are looking for.这正是你要找的人。

(先行词是the person, 引导词后紧跟的是you, 不是动词, 故引导词可用who / whom / that)考点2：先行词是物时引导词的选用

(1).先行词是物时，一般情况下引导词可以用which或that.如：

Mary like music that(which)is quiet and gentle.玛丽喜欢安静柔和的音乐。(先行词是music, 引导词可用which / that)The film which(that)we saw last night was very interesting.我们昨晚看的电影非常有趣。(先行词是film, 引导词可用which / that)。

Have you written down everything that Mr.Lin has said? 你写下林先生所说的每样东西了吗？ All that can be done has been done.能做的所有事情都己经做了。There is little that I can do for you.我能为你做的事几乎没有了。

②.当先行词由以下词修饰时，引导词只用that.这些词有：only, very, the same, the last, all, any, some, no, little, few等。如：

That is the very dress that I want to buy.那正是我要买的裙子。English is the only subject that I like.英语是我唯一喜欢的科目。Cleaning the room again is the last thing that I can do for you.再次打扫房间是我能为你做的最后一事。

③.当先行词有序数词或形容词最高级修饰时，引导词只用that.This is the fifth school that I have taught so far.这是我目前为止教过的第5所学校。Mr.Li’s class is the most interesting one that I have ever had.李老师的课是我上过的最有趣的课。

④.当先行词有人又有物时，只能用that。如：

Can you remember the writer and his books that we have reported? 拓展知识 考点3：先行词是时间，地点，原因时引导词的选用

(1).先行词是时间, 地点，原因并在从句中作状语时, 引导词分别用when, where, why, 也可以用介词+which结构。如：

I wanted to know the day when he was born.=I wanted to know the day on which he was born.我想知道他出生在哪一天。

He still loved the school where we studied together two years ago.=He still loved the school in which we studied together two years ago.他仍然爱那所我们两年前一起读书的学校。

Do you know the reason why he was late for school? 你知道他迟到的原因吗？(2).先行词是时间, 地点并在从句中作主语或宾语时, 引导词用which或者that。如： I remember the days which(that)we spent on the farm.我记得我们在农场渡过的日子。Lu Ming studies in the school which(that)was built 1 years ago.卢明在一所1年前建好的学校里读书。

考点4：引导词前有介词时，先行词是人,引导词只能用whom, 先行词是事物时，引导词只用which。如：

This is the friend to whom I talk a lot.这是跟我谈话很多的朋友。

Jacky stayed in the room in which Lu Xun once lived.杰克呆在那个鲁迅曾经住过的房间。

考点5：先行词是代词时，先判断其指代人还是指代物，再决定用哪个引导词。如： I don’t like those who talk much but do little.我不喜欢说得多做得少的人。The sleeping tigers are bigger than those which are trained there.这睡着的老虎们比那些被训练的大。宾 语 从 句

宾语从句是在主从复合句中作主句的宾语的句子。如：

Rose said she would visit us sometime next week.露丝说她下星期某时会来看我们。↓ ↓

主句 从句(宾语从句)Could you tell me where he is from? 你能告诉我他来自哪里吗？ ↓ ↓ 主句 从句(宾语从句)考点1：引导词的选用(1).陈述句的引导词用that，常可省略。

I am going to meet my net friends in Guangzhou.He said.→He said that he was going to meet his net friends in Guangzhou.他说他将要在广州见他的网友。

(2).一般疑问句的引导词用if/ whether(是否)。（后有or 时只用whether）Would you like to play basketball with me? He asked me.→He asked me if/whether I would like to play basketball with him.他问我是否会和他去打篮球。Is it a fast train or a slowly one? I wanted to know.→I wanted to know whether it was a fast train or a slowly one.我想知道这是快车还是慢车。

(3).特殊疑问句的引导词用特殊疑问词。How old are you? They want to know.→They want to know how old you are.他们想知道你多大年纪了。What are you going to do this afternoon? He asked me.→He asked me what I was going to do this afternoon.他问我今天下午要做什么。考点2：语序(宾语从句中从句要用陈述句语序，即从句中的第1助动词在主语之后）He asked Jane: “Why don’t you come”? 疑问语序(第1助动词don’t 在主语you之前)He asked Jane why she didn’t come last night.陈述语序(第1助动词didn’t 在主语you之后)Lucy wanted to know if I could make a cake for you.露丝想知道我是否会为你做个蛋糕。特殊：①.What’s wrong with „在宾语从句中不变语序。如： I want to know what’s wrong with you.我想知道你怎么啦。②.引导词在从句中做主语时，语序不变。如： Jack asked me who would give us the lecture this afternoon.杰克问我谁今天下午会给我们做报告。

(who 是引导词，在宾语从句中作动词would give的主语，本身己是陈述语序，不需再变。)考点3：时态（主句从句在时态上要一致）

(1).主句是现在时(一般现在时，一般将来时，现在进行时，现在完成时)，从句该用什么时态就用什么时态。

“John speaks highly of you.‖ Tom tells me.→Tom tells me that John speaks highly of me.汤姆告诉我约翰高度评价我。(主句用tells, 是一般现在时，从句原时态是speaks,在这里还是用speaks)He asked Jane why she didn’t come last night.陈述语序(第1助动词didn’t 在主语you之后)Lucy wanted to know if I could make a cake for you.露丝想知道我是否会为你做个蛋糕。

(2).主句是过去时(一般过去时，过去进行时)，从句只用过去某种相应时态。“When shall we have the meeting?” The boy asked.→The boy asked when they should have the meeting.男孩问他们应该什么时候开会。(主句用asked，是一般过去时，从句用相应的某种过去时，这里shall→should)(3).从句表示客观真理或事实时，主句即使用过去时，从句仍然用一般现在时。“The earth goes around the sun.” The teacher told the students.→The teacher told the students that the earth goes around the sun.老师告诉学生们地球绕着太阳走。

(主句用told, 为一般过去时，但从句中the earth goes around the sun是客观事实，所以时态还用一般现在时，不用变)Jim asked me whether the light travels faster than the sound.考点4：宾语从句答题技巧(逐步排除法)先用语序判断，再用时态求证，如有需要再用引导词及意思去决定)如：

()–Everyone wanted to know _______________ yesterday.Could you tell us, Ann? – By bus, of course.It was too far away.A.how old are you B.where you will go C.how you went there D.why you were late 先从语序判断，把A给排除了，再用时态去求证，主句用wanted，是一般过去时，从句该用过去的某种时态，从这一点考虑，把B给排除了，用引导词及意思判断，她的答语是By bus.故意思符合的只有答案C啦。2015年中考英语单项选择题汇编（宾语从句）20.－Excuse me, can you tell me _____? －At about 8 o’clock.（2015安顺）A.what time the plane arrive in Beijing B.what time the plane will arrive Beijing C.what time the plane will reach Beijing D.what time will the plane get to Beijing 参考答案：C 10.－Could you tell me _____ the Dragon Boat Festival in China? －Sure.People usually watch the dragon boat races and eat zongzi.（2015长沙）A.when do people celebrate B.why people celebrate C.how people celebrate 参考答案：C 5.－Do you know _____? －Yes.It’s on your table.（2015三亚）A.where my dictionary is B.where is my dictionary C.when I bought my dictionary 参考答案：A 17.－Do you know _____? －For a month.（2015天津）A.how long will she be away B.how long she will be away C.how often will she go there D.how often she will go there 参考答案：B 10.－I wonder _____.－Yes, of course.（2015德州）A.where we can buy the parts B.how often you hear form your sister C.if I may have a word with you D.why he arrived late yesterday 参考答案：C 15.一Excuse me, Miss Chen, could you tell me _____? —It is short for the Silk Road Economic Belt and 21st Century Maritime Silk Road.（2015福州）

第四篇：初中定语从句

七．定语从句

一.定语从句的概念

在复合句中，修饰某一名词或代词的从句叫定语从句。被修饰的名词或代词叫先行词，引导定语从句的词叫关系词，定语从句一般放在先行词的后面。

二.引导定语从句的关系词

引导定语从句的关系词有关系代词和关系副词，常见的关系代词包括that，which，who（宾格whom，所有格whose）等，关系副词包括where，when，why等。关系代词和关系副词放在先行词及定语从句之间起连接作用，同时又作定语从句的重要成分。三.定语从句的分类

根据定语从句与先行词的关系，定语从句可分为限制性定语从句及非限制性定语从句。限制性定语从句紧跟先行词，主句与从句不用逗号分开，从句不可省去。非限制性定语从句与主句之间有逗号分开，起补充说明作用，如省去，意思仍完整。四.关系代词的用法

1.that 既可以用于指人，也可以用于指物。在从句中作主语、宾语或表语。作主语时不可省略，作宾语可省略。例如：

Mary likes music that is quiet and gentle.玛丽喜欢轻柔的音乐。（that作主语）The coat（that）I put on the desk is blue.我放在桌子上的那件外套是蓝色的。（that作宾语）

2.which用于指物，在句中作主语、宾语或表语。作主语不可省略，作宾语可省略。例如： The building which stands near the train station is a supermarket.位于火车站附近的那座大楼是一家超市。（作主语）The film（which）we saw last night was wonderful.我们昨天晚上看的那部电影很好看。（作宾语）

3.who，whom用于指人，who 用作主语，whom用作宾语。在口语中，有时可用who代替whom。who和whom作宾语时也可省略。例如： The girl who often helps me with my English is from England.经常在英语方面帮助我的那个女孩是英国人。（作主语）Who is the teacher（whom）Li Ming is talking to？

正在与李明谈话的老师是谁？（作宾语）注意：

（1）当定语从句中含有介词，介词放在句末时，who，whom，that，which可省略，但介词在关系代词前时，只能用“介词+which/whom”结构。例如： This is the house in which we lived last year.这是我们去年居住的房子。

Please tell me from whom you borrowed the English novel.请告诉我你从谁那借的这本英文小说。

（2）含有介词的固定动词词组中，介词不可前置，只能放在原来的位置上。例如： This is the person whom you are looking for.这就是你要找的那个人。

（3）that 作介词的宾语时，介词不能放它的前面，只能放在从句中动词的后面。例如： The city that she lives in is very far away.她居住的城市非常远。

（4）关系词只能用that的情况：

a.先行词被序数词或形容词最高级所修饰，或本身是序数词、基数词、形容词最高级时，只能用that，而不用which.例如：

He was the first person that passed the exam.他是第一个通过考试的人。

b.被修饰的先行词为all，any，much，many，everything，anything，none，the one等不定代词指物时，只能用that，而不用which.例如： Is there anything that you want to buy in the shop？

你在商店里有什么东西要买吗？

c.先行词被the only，the very，the same，the last，little，few 等词修饰时，只能用that，而不用which.例如： This is the same bike that I lost.这就是我丢的那辆自行车。

d.先行词里同时含有人或物时，只能用that，而不用which.例如： I can remember well the persons and some pictures that I saw in the room.我能清楚记得我在那个房间所见到的人和一些照片。

e.以who或which引导的特殊疑问句，为避免重复，只能用that.例如： Who is the girl that is crying？

正在哭泣的那个女孩是谁？

f.主句是there be 结构，修饰主语的定语从句用that，而不用which，例如： There is a book on the desk that belongs to Tom.桌子上那本书是汤姆的。

（5）关系词只能用which，而不用that 的情况：

a.先行词为that，those时，用which，而不用that.例如： What’s that which is under the desk？

在桌子底下的那些东西是什么？

b.关系代词前有介词时，which，而不用that.例如： This is the room in which he lives.这是他居住的房间。

c.引导非限制性定语从句，先行词指事物时，用which，而不用that，例如： Tom came back，which made us happy.汤姆回来了，这使我们很高兴。五.关系副词的用法

1.when指时间，其先行词表示时间，when在定语从句中作时间状语。例如：

This was the time when he arrived.这是他到达的时间。

2.where指地点，其先行词表示地点，where在定语从句中作地点状语。例如： This is place where he works.这是他工作的地点。

3.why 指原因，其先行词是原因，why在定语从句中做原因状语。例如： Nobody knows the reason why he is often late for school.没人知道他为什么上学总迟到。

八．时间、条件、原因状语从句

状语从句指在句子中用作状语的从句。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等九种状语从句。

初中阶段，我们学习的状语从句主要有时间状语从句、条件状语从句和原因状语从句，今天我们就来学习以下这三种状语从句。一.时间状语从句

主要连词：when、while、as、as soon as（一......就......）、before、after、since等。

【注意1】时间状语从句要符合“主将从现”的原则：即主句用一般将来时，从句用一般现在时。例如：

I will call you as soon as I arrive in Beijing.我一到北京就给你打电话。

I will give you a call when I arrive at London.我到伦敦后会给你打电话。

【注意2】since 的用法： since引导的时间状语从句必须是一般过去时，其主句必须时现在完成时。例如：

Since I came to Beijing, I have lived here.自从我来到北京，我一直住在这里。

【注意3】while 引导的时间状语从句中，谓语动词必须时持续的;when 引导的时间状语从句中，谓语动词可以持续也可以不持续。例如：

While I was away last summer, my dog was taken good care of.我去年夏天离开的那段日子里，我的狗被照顾的很好。

When I lived in that small village，I often went to play in the field.当我住在那个小山村的时候，我经常去地里玩耍。

When the film ended，all the people began to go out of the cinema.电影结束后，所有的人都开始走出电影院。二.条件状语从句

主要连词：if, unless（除非=if...not...）, as long as（只要）等。【注意】条件状语从句要符合“主将从现”的原则：即主句用一般将来时，从句用一般现在时。例如：

If it is fine tomorrow，we will have a picnic outdoors.如果明天天气好，我们会在户外野餐。

Unless you work hard, you won't succeed.（=If you don't work hard, you won't succeed.）除非你努力工作，否则你不会取得成功。As long as you go, I will go.只要你去，我就会去。三.原因状语从句

主要连词：because, as（由于）, since（因为，既然）等。

【注意】because 引导的原因是未知的原因，as和since引导的原因是已知的原因。例如： I didn't go to school because I was ill.因为我病了，所以没有去上学。

As it is raining heavily, we won't go to the park.由于雨下得很大，我们就不去公园了。

Since everyone is here, let's begin our meeting.既然大家都到了，让我们开始我们的会议吧。
