宾语从句，表语从句，定语从句，状语从句 各自的定义是什么？

定语从句
定语从句是由关系代词和关系副词引导的从句，其作用是作定语修饰主句的某个成分，定语从句分为限定性和非限定性从句两种。状语从句分为时间状语从句，结果状语从句，让步状语从句，原因状语从句，条件状语从句以及行为方式状语从句。名词从句包括主语从句，宾语从句，表语从句和同位语从句及there be句型。

一、 限定性定语从句

1. that即可代表事物也可代表人，which代表事物；它们在从句中作主语或宾语，that在从句中作宾语时常可省略关系词，which在从句中作宾语则不能省略。而且，如果which在从句中作“不及物动词＋介词”的介词的宾语，注意介词不要丢掉，而且介词总是放在关系代词which的前边，但有的则放在它原来的位置

2. which作宾语时，根据先行词与定语从句之间的语义关系，先行词与which之间的介词不能丢

3. 代表物时多用which，但在带有下列词的句子中用that而不用which，这些词包括all, anything, much等，这时的that常被省略

4. who和whom引导的从句用来修饰人，分别作从句中的主语和宾语，whom作宾语时，要注意它可以作动词的宾语也可以作介词的宾语

5. where是关系副词，用来表示地点的定语从句

6. when引导定语从句表示时间

〔注〕值得一提的是，表示时间“time"一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导

By the time you arrive in London, we will have stayed there for two weeks.

I still remember the first time I met her.

Each time he goes to besiness trip, he brings a lot of living necessities, such as towers, soap, toothbrush etc.

7. whose是关系代词，修饰名词作定语，相当于所修饰成分的前置所有格

8. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时，常用there is来引导

二、非限定性定语从句：非限定性定语从句的作用是对所修饰的成分作进一步说明，通常和主句间用逗号隔开，将从句拿掉后其他部分仍可成立

1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分

2. 在引导限定性定语从句时，that有时相当于in which, at which, for which或at which

Attitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed. 人们对白日做梦的态度正在改变，这与人们对夜间做梦的看法的变化有非常相似之处。

I like the music for the very reason that(for which) he dislike it. 我出于某种原因喜欢这种音乐，而他恰恰与我相反。

We arrived the day that(on which) they left. 刚好我们到的那天他们走了。

3. 有时as也可用作关系代词

4. 在非限定性定语从句中，不能用that，而用who, whom代表人，用which代表事物.

一.定语从句及相关术语

1.定语从句：修饰一个名词或代词的从句称为定语从句，一般紧跟在它所修饰的先行词后面。

2.关系词：引导定语从句的关联词成为关系词

关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose, as等；关系副词有where, when, why等。

关系词常有3个作用：1，引导定语从句。2，代替先行词。3，在定语从句中担当一个成分。

二.关系代词引导的定语从句

1.who指人，在从句中做主语

(1) The boys who are playing football are from Class One.

(2) Yesterday I helped an old man who lost his way.

2. whom指人，在定语从句中充当宾语，常可省略。

(1) Mr. Liu is the person (whom) you talked about on the bus.

(2) Mr. Ling is just the boy whom I want to see.

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) The man who/whom you met just now is my friend.

3. which指物，在定语从句中做主语或者宾语，做宾语时可省略

(1) Football is a game which is liked by most boys.

(2) 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。在宾语从句中做主语或者宾语，做宾语时可省略。

(5) The number of the people that/who come to visit the city each year rises one million.

(6) 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

(1) He has a friend whose father is a doctor.

(2) I once lived in a house whose roof has fallen in.

whose指物时，常用以下结构来代替

(3) The classroom whose door is broken will soon be repaired.

(4) The classroom the door of which is broken will soon be repaired.

(5) Do you like the book whose cover is yellow?

(6) Do you like the book the color of which is yellow?

三.介词+关系代词引导的定语从句

关系代词在定语从句中做介词宾语时，从句常由介词+关系代词引导

(1) The school (that/which) he once studied in is very famous.

(2) The school in which he once studied is very famous.

(3) Tomorrow I will bring here a magazine (that/which) you asked for.

(4) Tomorrow I will bring here a magazine for which you asked.

(5) We’ll go to hear the famous singer (whom/that/who) we have often talked about.

(6) We’ll go to hear the famous singer about whom we have often talked.

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

(1) This is the watch which/that I am looking for. (T)

(2) This is the watch for which I am looking. (F)

2. 若介词放在关系代词前，关系代词指人时用whom，不可用who或者that；指物时用which，不能用that；关系代词是所有格时用whose

(1) The man with whom you talked is my friend. (T)

(2) The man who/that you talked with is my friend. (F)

(3) The plane in which we flew to Canada is very comfortable. (T)

(4) The plane in that we flew in to Canada is very comfortable. (F)

3. “介词+关系代词”前可有some, any, none, both, all, neither, most, each, few等代词或者数词

(1) He loved his parents deeply, both of whom are very kind to him.

(2) In the basket there are quite many apples, some of which have gone bad.

(3) There are forty students in our class in all, most of whom are from big cities.

四．关系副词引导的定语从句

1. when指时间，在定语从句中做时间状语

(1) I still remember the day when I first came to the school.

(2) The time when we got together finally came.

2. where指地点，在定语从句中做地点状语

(1) Shanghai is the city where I was born.

(2) The house where I lived ten years ago has been pulled down.

3. why指原因，在定语从句中做原因状语

(1) Please tell me the reason why you missed the plane.

(2) I don’t know the reason why he looks unhappy today.

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

(1) The reason why/ for which he refused the invitation is not clear,

(2) From the year when/in which he was going to school he began to know what he wanted when he grew up.

(3) Great changes have taken place in the city in which./where I was born.

五．限制性定语从句和非限制性定语从句

限制性定语从句 非限制性定语从句

形式上 不用逗号和主句隔开 用逗号和主句隔开

意义上 是先行词不可缺少的定语，不能删除 是对先行词的补充说明，删除后意思仍完整

译法上 翻译成先行词的定语，“…的…” 通常翻译成主句的并列句

关系词的使用上 A．做宾语时可省略 B。可用that

C．可用who代替whom A．不可省 B。不用that

C。不用who代替whom

限制性定语从句举例：

(1) The teacher told me that Tom was the only person that I could depend on.

(2) China is a country which has a long history.

非限制性定语从句举例：

(1) His mother, who loves him very much, is strict with him.

(2) China, which was founded in 1949, is becoming more and more powerful.

要注意区分以下几个句子的不同

(1) 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）

(2) 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）

难点分析

（一）限制性定语从句只能用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

(1) Have you taken down everything that Mr. Li has said?

(2) There seems to be nothing that seems impossible for him in the world.

(3) All that can be done has been done.

(4) 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

(4) 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

(1) 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

(1) This is the best film that I have seen.

4. 当形容词被the very, the only 修饰时

(1) This is the very dictionary that I want to buy,

(2) After the fire in his house, the old car is the only thing that he owned.

当先行词指人时，偶尔也可以用who

(3) 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

(1) Who is the man that is standing there?

(2) Which is the T-shirt that fits me most?

6. 当先行词既有人，也有动物或者物体时

(1) Can you remember the scientist and his theory that we have learned?

（二）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

(1) As is known to all, China is a developing country.

(2) He is from the south, as we can see from his accent.

(3) John, as you know, is a famous writer.

(4) 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

(5) 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

(1) I have never heard such a story as he tells.

(2) He is not such a fool as he looks.

(3) 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

(4) 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。

(5) 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。

（三）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。

(1) The way in which/ that/./ he answered the question was surprising.

(四) but有时也可以做关系词引导定语从句

(1) There are very few but understand his idea. ( but= who don’t )

(五) 区分定语从句和同位语从句

1．定语从句修饰先行词，它和先行词是修饰关系；同位语从句说明先行词的具体内容，是补充说明的关系

(1) The plane that has just taken off is for London. 定语从句

(2) The fact that he has been dead is clear. 同位于从句

2．定语从句由关系代词或者关系副词引导，关系词在句中充当成分，有时可以省略；同位语从句主要由that引导，在句中一般不做成分；句子也可以由when, where, how, why, whether, what等词引导，充当成分

(1) The news he told me is true.

(2) The news that he has just died is true.

(3) The problem that we are facing now is how we can collect so much money. 定语

(4) The problem how we can collect so much money is difficult to solve.

3. 同位语从句和先行词一般可以用be动词发展成一个完整的句子，而定语从句不可以

(1) The idea that we could ask the teacher for advice is wonderful. 同位语

(2) The idea was that we could ask the teacher for advice.

(3) The fact that the earth moves around the earth is known to all.

(4) The fact is that the earth moves around the earth.

一、状语从句分类及常用连词：
类别 连 词
时间状语从句 when, whenever, while, as, before, after, since, till, once, as soon as,etc.
地点状语从句 where,wherever
原因状语从句 because, since, as, for, now that, etc.
目的状语从句 in order that, so that, that, etc.
结果状语从句 so…that, so that, such…that, that, etc.
条件状语从句 if, unless, as(so)long as, etc.
让步状语从句 though, although, even if, even though, however, whatever, as,etc.
比较状语从句 as…as, so…as, than, etc.
方式状语从句 as, as if, as though, etc.

二、相似连词的用法区别
1.when, while, as,
while表时间，从句需用延续性动词，切不可用瞬间动词。
when表时间，从句既可以用延续性动词，又可以用瞬间动词。
as表时间，与when相似，但侧重强调主从句动作同点或同段进行。
when, while后可以接分词短语。
2.because, as, since, for

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

注：上面所说的“前”，指从句在主句之前；“后”，指从句在主句之后。

3.so that, so…that, such…that
so that “以便”、“结果”表目的和结果。注意：在从句中有情态动词表目的。无情态动词表结果。

so…that “如此的…以致于”表结果。该结构常见于：
1.so+形／副＋that 2.so+形＋a(an)＋单数名词＋that 3.so＋many/much＋复数名词（不可数名词）+that

such…that “如此的…以致于”表结果。该结构常见于：
1.such＋a(an)＋形＋名词＋that 2.such＋形＋复数名词／不可数名词＋that

4.though, although, as,
though, although在句首表“尽管”两者都可以用。但句后不能再用but。
下列情况只能用though：
▲ as though (=as if); even if (=even though)
▲ 在句末表示“然而”
as表示“尽管”，从句的表语、状语等成分要倒装。

5.whatever, however,wherever, whenever
它们是what, how, where, when的强势语气。分别等于：
no matter what, no matter how
no matter where, no matter when

二宾语从句
1.肯定句
结构:主句+that（可有可无）+肯定句
2.一般疑问句
结构:主句+if+一般疑问句
3.特殊疑问句
结构:主句+疑问词+肯定句。
宾语从句的时态
1.主现从不限（主句是一般现在时，从句的时态不限）
2.主过从四过（主居是一般过去时，从句的时态应是一般过去时、过去完成时、过去将来时或者过去进行时）
在复合句中用作宾语的从句叫做宾语从句。宾语从句是初中英语中最重要的一种从句，它内容完整，句型结构较为复杂，主句和从句时态搭配要求严格，在中考试题中频频出现。而且学好宾语从句也可为到高中学习间接引语、主语从句、表语从句及同位语从句打下良好的基础。学习宾语从句并不难，只要你能过好下面的三道关：
第一关，选好连接词（也有人叫关联词）。
引导宾语从句的连接词，课本上写有三类，但从学习的角度看分为四类更为实用。
1．连词that：只起连接作用，在从句中不作句子成分，也无词汇意义，在口语中或非正式文体中常被省略。例如：
1）He knew（that）he should work hard．
2）I am glad（that）you\'ve passed the exam．
2．连词whether或if：它们起连接作用，在从句中不作句子成分，作“是否”解，口语中多用if。例如：
3）Do you know whether he will ride here at 8 tomorrow morning？（注：2002上海市徐汇区中考试题填上答案后的句子。以下再有这种例句，都为2002年中考题，只写某地。）
4）Tom didn\'t know if／whether his grandpa liked the present．
作“是否”解的if和whether在具体用法上差别较大，同学们不易掌握。在宾语从句中用whether没有用if时受到那么多限制。例如：
5）He asked me whether or not I was coming．他问我是否要来。（该句中的whether不能换成if，因为if不能与or连用。）
3．连接代词who，whom ，whose，what， which：它们起连接作用，作句子成分，各有其自己的意义。例如：
6）The teacher asked the new student which class he was in？（武汉市）（which引导宾语从句，在从句中作定语，修饰class，意为“哪个”。）
7）Can you tell me whom he is waiting for？（天津市）
4．连接副词when，where， why，how：起连接作用，分别作时间、地点、原因、方式状语，各有其自己的意义。例如：
8）I wonder where he got so much money．对他从哪里弄到那么多钱我感到疑惑。（where在从句中作地点状语，修饰got，意为“哪里；什么地方”。）
9）He didn\'t tell me how old his friend was．（四川省）（how引导宾语从句，作程度状语，修饰old，意为“怎样；如何”等意。）
第二关，牢记宾语从句的语序是陈述句语序，即“连接词＋主语＋谓语＋其他”。这里特别强调的是，它的主语和谓语的语序是陈述句的语序，不是疑问句的倒装语序。例如：
10）You must remember what your teacher said．（河南省）
11）—Dad，do you know when the football game will start？
—In half an hour．（宁波市）
12）汉译英：你能不能告诉我，我们去看望谁？
误：Can you tell me who（m）do we have to see？
正：Can you tell me who（m）we have to see？
错句的错误出在宾语从句中误用了疑问句的结构——主语前加了个助动词do。因为我们已经习惯了特殊疑问句，如W hat time does the plane arrive in Paris？就顺口说出“Do you know what time does the plane arrive in Paris？”这种错误句子来。但是一旦我们注意了，我们不久就习惯于说“Do you know what time the plane arrives in Paris？”了。
第三关，注意时态的呼应。
宾语从句中谓语动词的时态，常常受主句谓语时态的制约，这种现象称为“时态的呼应”。例如：
13）汉译英：我原以为你今天有空的。
误：I thought（that）you are free today．
正：I thought（that）you would be free today．
错句中宾语从句用are很可能是因为有 today，但因为主句谓语是thought，所以从句谓语就该用过去将来时would be了。
这种时态的呼应，如果主句谓语是现在时或将来时，宾语从句的谓语时态不受限制，如上述例句2），3），7），8），10），11），12）。如果主句时态是过去时，宾语从句一般要随着改为相应的过去时（即一般过去时、过去进行时、过去完成时、过去将来时等）。例如：
14）He thought he was working for the people．
15）I heard she had been to the Great W all．
16）John hoped that he would find a job soon．
但宾语从句如果表示定理法则、永恒真理等，则不变化：
17）The teacher told us that the earth moves around the sun

内容提要

定语从句是由关系代词和关系副词引导的从句，其作用是作定语修饰主句的某个成分，定语从句分为限定性和非限定性从句两种。状语从句分为时间状语从句，结果状语从句，让步状语从句，原因状语从句，条件状语从句以及行为方式状语从句。名词从句包括主语从句，宾语从句，表语从句和同位语从句及there be句型。

3. 有时as也可用作关系代词

4. 在非限定性定语从句中，不能用that，而用who, whom代表人，用which代表事物

希望我的回答对您有帮助，祝您学习进步，工作顺心。^_^

很简单啊。宾语从句和表语从句都属于名词性从句。其作用跟名词在句中的作用相同。故充当宾语的句子叫宾语从句，充当表语的句子叫表语从句。
定语从句是由关系代词和关系副词引导的修饰名词的句子。
状语从句是在主从复合结构中修饰动词，形容词，副词的从句。
