同位语从句与定语从句

同位语从句与定语从句（共6篇）

篇1：同位语从句与定语从句

定语从句与同位语从句的区别

一、从词类上区别

同位语从句前面的名词只能是idea, fact, news, hope, belief, suggestion, proposal, word, thought, doubt, truth, possibility, promise, order等表示抽象意义的名词。而定语从句的先行词可以是名词、代词、主句的一部分或整个主句。如：

We are looking into the question whether he is worth trusting.我们正在调查的是他是否值得信赖的问题。（同位语从句）

Word came that he had gone abroad.据说他已经出国了。（同位语从句）

The doctor whom you are looking for is in the room.你找的那位医生在房间里面。（定语从句，名词the doctor作先行词）

Our team has won the game, which makes us very happy.(定语从句，which代表前面提到的整个句子)His mother did all she could to help him with his study.他妈妈尽最大努力帮他学习。（定语从句，代词all作先行词）

二、从性质上区别

定语从句是从句对其先行词的修饰或限制，属于形容词性从句的范畴；而同位语从句是从句对前面抽象名词的进一步说明和解释，属于名词性从句的范畴。如：

The news that our team has won the game is true.我们队赢了那场比赛的消息是真的。(同位语从句，补充说明news的内容。）

The news(that)he told me yesterday is true.昨天他告诉我的那个消息是真的。

(定语从句，that 从句作定语修饰news

I made a promise that if anyone set me free I would make him very rich.我许诺如果谁让我自由，我就让他非常富有。(同位语从句，补充说明promise)The mother made a promise that pleased all her children.妈妈做出了一个令她的孩子们高兴的许诺。(定语从句，that从句作定语修饰promise

三、从引导词及其在句子中的成份上区别有些引导词如how, whether, what可以引导同位语从句，但不能引导定语从句。如:

That question whether we need it has not been considered.我们是否需要它这个问题还没有考虑。同位语从句）

引导词that引导定语从句时，在从句中一般作主语或宾语（指物时还可以用which代替），并且作宾语时常常省略。

That在同位语从句中仅起连接作用，不充当任何成份，并且不能省略，也不能用 which来代替。

The order that we(should)send a few people to help the other groups

was received yesterday.我们应派几个人去帮助别的几个小组的命令昨天已收到了。

同位语从句，是对order的具体解释，(that虽不作成份，但不能省略）

The order(that)we received yesterday was that we(should)send a few people to help the other groups.我们昨天收到的命令是我们应该派几个人去帮助别的几个小组。定语从句，是名词order的修饰语，that在从句中作received的宾语，可以省略）

定语从句与强调句型的区别

强调句型的句式结构为：“It is/was + 被强调部分 + that/who从句”。在强调时间、地点、原因或方式状语时，一律用that，而不用when, why或how；在强调主语和宾语时，如果主语和宾语指代人，则可用who和whom来代替that, 但是从句中的人称和数要

与被强调的主语和宾语保持一致。这些都容易与定语从句混淆。

定语从句和强调句型的判断方法：若将句中的“It is/was”和“that/who”去掉，而句子不缺成分，结构完整，说明原句是强调句型；若句子结构不完整，则说明原句为定语从句。定语从句中的主谓一致

1、当关系代词作从句的主语时，那么从句的谓语必须与先行词保持一致。

e.g.Last Sunday we visited a farm which is located in the suburbs

of Hangzhou.Those who are present at the meeting are all lawyers.2、one of + 名词后面的定语从句谓语用复数； the(only)one +名词后面的定语从句谓语用单数。

e.g.Jack is one of the journalists who know Russian but the only one who knows French in our News Agency.3、主语是I，时态是一般现在时，谓语be动词用am.e.g.I, who am your close friend, will offer you a room for free

篇2：同位语从句与定语从句

一、定语从句

1.定语从句在句中做定语，修饰一个名词或代词，被修饰的名词、词组或代词即先行词。定语从句通常出 现在先行词之后，由关系词（关系代词或关系副词）引出。关系代词有：who, whom, whose, that, which； 关系副词有：when, where, why。2.限制性定语从句与非限制性定语从句

（1）限制性定语从句是先行词在意义上不可缺少的定语，用于修饰和限定先行词。如果去掉，主句的意

思就不完整或失去意义。书写时不用逗号与先行词分开。例：This is the boy who broke the window.（2）非限制性定语从句在意义上只是一个附加修饰语，对先行词或主句作些附加的说明。如果去掉，主

句的意思仍然清楚。书写时往往用逗号与先行词分开。例：I, who am your friend, will share the work with you.3.非限制性定语从句的“四个不能”：（1）非限制性定语从句通常不能用that引导。

（2）非限制性定语从句不能用why引导，要用for which 代替。例：I had told them the reason, for which I didn’t attend the meeting.（3）由“介词+关系代词”引导时，关系代词不能用as。（4）指人的关系代词作宾语时用whom，不能省略。4.在定语从句中，下列情况的关系词用that而不用which:（1）先行词被形容词最高级、序数词、数词等几种词修饰或被only, any, few, little, no, all, one of等修饰时。例：This is the best film that I have ever read.（2）先行词为all, much, little, none, few, one, something, everything, anything等不定代词时。

例：He told me everything that he knows.（3）先行词中既有人又有物时。

例：He was looking pleasantly at the children and parcels that filled his bus.（4）先行词在主句中作表语或关系词在定语从句中作表语时。例：The village is no longer the one that was 5 years ago.（5）当主句中含有疑问词which时；或者句中已经有who或which，为了避免重复时。

例：Which are the books that you bought for me ? 5.其他注意事项

（1）当the way做先行词时，只用that, in which或不用关系词。例：What surprised me was not what he said but the way he said it.（2）在限制性定语从句中，名词前有such和the same修饰时，关系代词用as不能用which。例：Don’t read such books as you can’t understand.（3）在非限制性定语从句中，as和which都可以指代前面整个主句。如果有“正如，像”的含义，可以 放在主句前，也可以放在后面，那么用as；而which引导的从句只能放主句后，并无“正如”的意思。例：They won the game, as we had expected.They won the game, which we hadn’t expected.6.定语从句与先行词被分割开来的现象

定语从句一般紧接被它所修饰的先行词；但有时候它和先行词之间有可能插入其他成分，使它与先行词分隔开来，这种定语从句叫作被分隔的定语从句。在阅读文章时会经常遇到这种情况，阅读时要注意识别先行词的修饰对象。

（1）在定语从句加中插入语，常见的有：I think,I suppose,I guess,I imagine等。辨别的方法是：去掉插入 语后，原句句法结构仍然完整。

例：He made another wonderful discovery,which I think isof importance to science.（2）在先行词与定语从句之间插入一个状语。

例：There are many thousands of stars in the sky that are like the sun.（3）在先行词与定语从句之间插入一个定语。

例：Do you remember one afternoon ten years ago when I came to your house and borrowed a diamond necklace? 你还记得吗，十年前的一天下午，我来到你家，找你借了一条钻石项链？

（4）先行词与定语从句被谓语分隔开来。此时，先行词通常是句子的主语，因定语从句较长，主句谓语

较短，为使句子平衡，常将定语从句移至谓语之后。例：A new master will come tomorrow who will teach you German.7.几个特殊的定语从句句型

（1）He is the only one of the students who has got very good marks in the match.（句中one为先行词）He is one of the students who have got good marks in the match.（句中students为先行词）（2）Is this place the one(that)we visited yesterday?（句中the one为先行词）Is this the place(that / which)we visited yesterday ?（句中 the place为先行词）（3）He stood at the window,from where he could see what was happening.（4）It may rain, in which case the match will be put off.8.定语从句的做题方法：（1）找出主句，确定先行词；

（2）找出从句，判断从句是否完整（是否符合简单句的基本构成）---否，用关系代词；是，用关系副词。

二、同位语从句

1.同位语从句就是在复合句中作名词的同位语的名词性从句。

同位语从句对名词进一步解释，说明名词的具体内容，一般由that引导，而且不能省略。例：The king’s decision that the prisoner would be set free surprised all the people.2.同位语从句有时可以不紧跟在它所说明的名词后面，而是被别的词隔开。例：He got the news from Mary that the sports meeting was put off.三、定语从句与同位语从句的区别

1.定语从句中的that既代替先行词，同时可以在从句中作某个成分（主语或宾语）；而同位语从句中的that 是连词，只起连接主句与从句的作用，不充当句中任何成分。

2.定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述先行词的性质或特征；同位语 从句是名词性的，其功能是对名词进行补充说明。

例：The news that he told me is that Tom would go abroad next year.第一个that引导的从句是定语从句，that在从句中作宾语。The news that Tom would go abroad is told by him.同位语从句，that在句中不作任何成分，用于说明news的内容。

【注意】当主句的谓语部分过短时而从句过长时，同位语从句放在谓语动词的后面，避免头重脚轻。例：Word came that our team had won the game.四、定语从句与状语从句的区别

1.定语从句的前面有名词作先行词，而状语从句没有先行词。

例：This is the place where we used to live a few years ago.这是几年前我们居住的地方。（定语从句，先行词为the place）Let’s go where we can find a better job.我们到能找到更好的工作的地方去吧。（地点状语从句）

2.定语从句修饰、限制、说明名词，只能放在先行词的后面，而状语从句说明动作发生的情况，并且可以 放在主句的前面。

例：Do you know the time when the class is over? 你知道下课的时间吗？（定语从句）

When the class was over, it was already five o’clock.当下课时己经是5点了。（时间状语从句）3.When, where和why在引导定语从句时可以用“介词＋which”的结构来替换，在引导状语从句时却不行。例：This is the factory in which(where)his father once worked.这就是他的父亲曾经工作过的那个工厂。（定语从句）

Put back the book where it was.把书放回原处。（状语从句）

4.定语从句中的关系词在从句中充当某种句子成分，因此去掉它则从句成分不完整；而结果状语从句中的 连接词在从句中不作任何成分，去掉后从句的成分仍然完整。例：It is such an interesting book as we all like.as用作动词like的宾语，它引导的是定语从句。It is such an interesting book that we all like it.that不充当句子成分，故它引导的是结果状语从句。

五、强调句

1.强调句型的基本结构：It is/was + 被强调部分（主语、宾语、宾语补足语或状等）+ that/who +句子 的其余部分。

例：It was yesterday that Mary met an old beggar in the street.（强调时间状语）2.强调句中含有not until的句子

在强调not until句型时，not 位于until从句前，主句谓语动词作相应变化，即 itis(was)+not until +从句或者短语 +that+其它..例：It was not until he had finished the work that he went home.六、定语从句与强调句的区别

1.定语从句中关系词作从句成分，关系词作宾语时可省略；强调句中that / who没有任何意义且不能省略。

2.强调句中的it无意义，that / who不是引导词。

3.强调句it is / was和that / who后如果句子意思讲得通则是强调句，讲不通则不是。

例：It is the museum that / which we visited last year.（定语从句）It was in the hotel that we stayed last night.（强调句）

例题赏析：

1.There’s a feeling in me we’ll never know what a UFO is – not ever.A.that

B.which

C.of which

D.what 【解析】此题考查同位语从句that的用法。that引导同位语从句修饰a feeling，只是做补充成分而已。句 意是我内心有种感觉我们永远不会知道UFO是什么—从来也不知道。故此题选A.2.His uncle works in a factorybicycles are made． A.that B.which

C.where

D.there 【解析】此题考查定语从句关系副词的用法。bicycles are made in the factory, 此处缺少介词in,故需用关系

副词来引导，where相当于in which，因此选择C.练习

篇3：同位语从句与定语从句

一、从意义的角度来看

同位语从句与先行词之间存在的是同位或同等的关系, 起到对名词的解释、补充说明作用。而定语从句与先行词之间存在的是所属关系, 表示“……的”, 起到对名词 (先行词) 进行修饰限定的作用。例如:

The chances that we will all have the opportunity to live in an English-speaking country are small. (M7 P6, that引导的同位从句与先行词chances是同位关系。)

我们都有机会生活在一个说英语的国家的这种机遇是很小的。

I turned around and glared at the person who was singing. (M5P14, who引导的定语从句限定先行词the person。)

我转过身来, 瞪了正在唱歌的那人一眼。

二、从语法内涵的角度来看

同位从句与所说明的先行词之间没有任何逻辑关系, 即先行词在从句中不充当任何成分。定语从句所限定的名词 (先行词) 是定语从句中逻辑上的主语、宾语、表语、定语、状语等。例如:

(1) The news that they won the match is true. (同位语从句, news与从句没有逻辑关系)

他们比赛获胜的这一消息是真实的。

(2) The news that you told us yesterday is true. (定语从句, news是从句中told的逻辑宾语)

你昨天给我们讲的消息是真的。

(3) The order when we should return hasn’t reached us. (同位语从句, order和从句没有逻辑关系)

我们什么时候该返回的命令还没到。

(4) The day when New China was founded will never be forgotten. (定语从句, day是从句中founded的逻辑时间状语)

人们永远不会忘记新中国成立的那一天。

三、从语法结构形式来看

同位从句由连词引导, 同位从句紧接在先行词之后, 有时为了句子平衡的需要被别的词把它和先行词隔开, 但从句前一般不用逗号。而定语从句是由关系词引导, 限定性定语从句常常紧接先行词后, 非限定性定语从句可以和先行词分离, 而且从句前需有逗号和主句分开。此外, 引导同位从句的连词不可省掉, 而引导定语从句的关系代词 (that, which, whom等) 作从句的宾语时常可省略。例如:

(1) The idea that the Internet will have taught English to everyone in the world by 2050 is amazing. (M7 P7同位语从句)

到2050年因特网将教会世界上每个人英语, 这个想法令人惊异。

(2) Word came that our duties would be changed. (M7 P100同位语从句)

据说, 我们的任务要有变化。

(3) As is often the case, we have worked out the productionplan. (非限定性定语从句)

像平常那样, 我们已制定出产品方案。

(4) His two sons are abroad, both of whom are graduate stu-dents. (非限定性定语从句)

他的两个儿子在国外, 两个都是研究生。

(5) After 1848, it (American English) was also influenced by immigration from Germany, Central Europe and Italy, which brough large numbers of new words into the language. (M7 p16非限定性定语从句)

1848年以后, 美国英语还受到来自德国、中欧、意大利移民的影响, 这为美国英语带来了许多新词。

(6) Education is what remains when we have forgotten all we have been taught. (M5 P39限定性定语从句, all后省掉了关系代词?that)

教育就是我们已经忘记了自己被叫过的东西后留下来的内容。

四、从先行词的性质来看

同位语从句的先行词大都是抽象概念的名词:fact, evi-dence, belief, question, idea, news, knowledge, hope, order, possibility, problem, reply, remark, report, suggestion, thought, word等。而定语从句的先行词则没有限制, 可以是名词, 也可以是代词或句子。例如:

(1) I had no idea when the train crash happened. (同位语从句, 先行词idea为抽象名词M7 P100)

我不知道火车碰撞事故什么时间发生的。

(2) She was the girl I had shouted at for singing. (定语从句, 先行词girl为名词M5P14)

她正是因她唱歌我对她大嚷的女孩。

(3) Those who want to go (定语从句, 先行词those为代词) , please sign their names here.

想去的人请在这里签名。

(4) This is the room where I lived ten years ago. (定语从句, 先行词room为名词)

这是我十年前住在那儿的房间。

(5) In addition, I am also a good photographer, which migh be useful for some of the articles. (非限定性定语从句, 先行词为句子M5 P30)

此外, 我还是一位很好的摄影师, 这可能对写这类文章有用。

(6) The exams were put off, which was exactly what we want-ed. (非限定性定语从句, 先行词为前面整个句子)

各门考试都推迟了, 这正是我们希望的。

五、特殊的what和whether

what和whether可用来引导同位语从句, 但是不能用来引导定语从句。例如:

(1) I gave the girl a big doll, exactly what she longed to have.

我给了这个女孩一个大洋娃娃, 那正是她渴望拥有的东西。

(2) The question whether it’s going to last a lifetime remains unanswered. (M7 P100)

是否这会延续一生, 这个问题仍未得到回答。

篇4：定语从句和同位语从句的区别

一、 定语从句是形容词从句,其作用相当于一个形容词,是用来修饰前面的名词或代词的;同位语从句是名词从句,其作用相当于一个名词,是对前面的名词作进一步解释的。例如:

1. We heard the news that he had told her. 我们听到他对她说的消息。

2. We heard the news that he had won the game. 我们听到消息他赢得了比赛。

例1中的that从句的作用相当于一个形容词,其作用是修饰the news;例2中的that从句的作用相当于一个名词,是对the news的进一步说明。

二、定语从句的引导词在从句中充当一定的成分,可作主语、宾语、状语等;而同位语从句中的引导词在从句只起连接作用,不作任何句子成分。例如:

1. A plane is a machine that can fly. 飞机是一种能飞的机器。

2. The fact that they didn’t finish the work has to be faced. 必须面对事实,他们没有完成工作。

例1中的引导词that在从句中充当句子成分,作从句的主语,故为定语从句;例2中that只起连接作用,引导从句解释fact的内容,不作任何句子成分,故为同位语从句。

三、引导定语从句的关联词在从句中作宾语或状语时,可以省略或被其他词代替;而同位语从句的引导词一般不能省略,更不能被代替。例如:

1. The news that she heard is true. 她听到的消息是真的。

2. The news that she will go abroad is true. 她将出国这消息是真的。

例1是定语从句, that可省略;例2是同位语从句,that不能省略。

3. The reason why he was chosen remains unknown. 他为什么被选上的原因还是不清楚。

4. The idea why he was chosen attracted our attention. 他为什么会被选上,这一想法引起我们的注意。

例3中why引导的是定语从句,why可以被 for which或 that 代替;例4中 why引导的是同位语从句,why 不能省去,也不能被其它词代替。

四、同位语从句与其所修饰的名词之间是同位关系,二者之间存在逻辑上的系表关系,可用“主 + 系 + 表”结构来表示。例如:

The news that he won the first place is true. 他赢得冠军的那个消息是真的。

上句若用“主 + 系 + 表”结构来表示,则是: The news is that he won the first place. 消息是他赢得了冠军。意思合理,系表结构成立,故为同位语从句。

五、定语从句所修饰、限定的先行词可以是各类名词,可以有复数形式;而同位语从句一般都与抽象名词同位,一般没有复数形式。例如:

1. The possibilities that she was offered seemed very great.她得到的可能性似乎大些。

2. Her mother was worried about the possibility that her daughter dislike to go to school. 她的母亲很担心,她女儿有可能不喜欢上学。

例1中的possibilities是定语从句的先行词,可用复数形式;例2中的possibility是抽象名词,后接的是同位语从句,一般不用复数形式。

六、由when, why, where引导的定语从句分别修饰或说明表示时间、原因或地点的词,但它们引导的同位语从句一般不和表示时间或地点的词同位。例如:

1. I still remember the day when I first came to Beijing. 我仍然记得初次来北京的那天。

2. I have no idea when she will be back. 我不知道她何时回来。

3. This is the house where I lived two years ago. 这是我两年前住的房子。

例1、3中的when和 where引导的是定语从句,day 和house分别表示时间和地点;例2中的when引导的是同位语从句。

篇5：同位语从句与定语从句

同学们在考研语法学习中经常容易混淆同位语从句和定语从句，对两种从句的混淆有时会直接影响到阅读文章的准确理解及翻译句子正确翻译方法的采用，以下对两种从句的区分方法进行专项总结，以便同学们轻松掌握。两种从句的区别主要在以下三方面:

1. 从词类上区别

同位语从句前面的名词只能是idea, fact, news, hope, belief, suggestion, proposal, word, thought, doubt, truth, possibility, promise, order等有一定内涵的名词，而定语从句的.先行词可以是名词、代词，主句的一部分或是整个主句，如:

The possibility that the majority of the labor force will work at home is often discussed.人们经常讨论大多数劳动力将会在家里工作的可能性。(同位语从句)

Our team has won the game, which made us very happy. 我们的队赢了,这让我们很高兴。(定语从句)

2. 从性质上区别

定语从句是从句对其先行词的修饰或限制,属于形容词性从句的范畴;而同位语从句是从句对前面抽象名词的进一步的说明和解释,属于名词性从句的范畴，如:

The news that our team has won the game was true. 我们队赢了那场比赛的消息是真的。(同位语从句,补充说明news到底是一个什么消息。)

The news that he told me yesterday was true. 昨天他告诉我的那个消息是真的。(定语从句,news在从句中作told的宾语。)

3. 从引导词及其在句子中的成分上区别

有些引导词如how, whether, what可以引导同位语从句,但不能引导定语从句，如:

That question whether we need it has not been considered. 我们是否需要它这个问题还没有考虑。(同位语从句)

引导词that引导定语从句时,在从句中一般作主语或宾语(指物时还可以用which代替),并且作宾语时常常省略，that在同位语从句中仅起连接作用,不充当任何成分,并且不能省略,也不能用which来代替，如:

The order that we should send a few people to help the other groups was received yesterday. 我们应派几个人去帮别的几个小组的命令昨天收到了。(同位语从句,是对order的具体解释,that虽不作成分,但不能省略。)

The order that we received yesterday was that we should send a few people to help the other groups. 我们昨天收到的命令是我们应该派几个人去帮助别的几个小组。(定语从句,是名词order的修饰语,that在从句中作received的宾语,可以省略。)

【真题例句】

The issue of whether life ever existed on the planet, and whether it persists to this day, has been highlighted by mounting evidence that the Red Planet once had abundant stable, liquid water and by the continuing controversy over suggestions that bacterial fossils rode to Earth on a meteorite from Mars.

【解析】

句子可拆分为：The issue of //whether life ever existed on the planet, and whether it persists to this day, //has been highlighted //by mounting evidence //that the Red Planet once had abundant stable, liquid water and //by the continuing controversy over suggestions //that bacterial fossils rode to Earth on a meteorite from Mars.

主句为：The issue of whether life ever existed on the planet, and whether it persists to this day, has been highlighted by… and by…。主句主语的结构为: The issue of whether…and whether…。of 短语修饰the issue, of 短语较长一般译在后面;that the Red Planet…是evidence的同位语从句，(即是evidence的具体内容)。that bacterial fossils…是suggestions的同位语从句，说明suggestions的具体内容。)第一个同位语从句可以直接翻译在所修饰词后面。第二个同位语可以放在所修饰的名词前面，充当定语。

【参考译文】

篇6：定语从句与其他从句的区别1

1.限制性定语从句与同位语从句的区别

关系副词引导限制性定语从句中的关系词有跟他们含义相应的先行词，而引导同位语从句时则没有与他们含义相应的先行词。如：

Sorry, I’ve forgot the day when we met for the first time.抱歉，我记不起我们第一次见面的日子了。(定语从句，先行词the day 与when含义相应)

I’ve no idea when we met for the first time.我不知道我们第一次是什么时候见面的。(同位语从句，idea与when没有任何联系)

2.定语从句与时间语状语从句的区别

当定语从句的引导词与时间状语的连接词都是when时，定语从句修饰、限制、说明时间名词，只能放在先行词的后面；而时间状语从句说明动作发生的情况，并且可以放在主句的前面。如(from )：

Do you know the time when the class is over? 你知道下课的时间吗？(定语从句)It was already five o’clock when the class was over.—When the class was over, it was already five o’clock.当课结束时，已经是五点钟了。(时间状语从句)

3.定语从句与地点状语从句的区别

当定语从句的引导词与地点状语的连接词都是where时，定语从句修饰、限制、说明地点名词；而状语从句说明动作发生的地点，where没有对应的地点名词或代词。如：

This is the place where we used to live a few years ago.这就是几年前我们常居住的地方。(定语从句)

Let’s go where we can find a better job.我们到我们能找到更好工作的地方去吧。(地点状语从句)

4.定语从句与强调句型的区别

定语从句对名词或代词的修饰和限制，关系词可能是that, which, as, who, but, 另一方面，句子中的It有所指；而强调句型是对某部分加强语气，而强调语气的连接词只能是that, who，并且句子中的It 没有任何意义；一般比较明显，而有时就难以区别，还需要根据上下文的语境来判断。如(from )： It is a book that he wants.它究竟是强调句型还是定语从句，就要从语境上来考察。如果它是用来回答What is this / that? 这样的问题，意思是：它是一本他想要的书。句子显然是定语从句。如果是用来回答What does he want?这样的问题，那么意思是：他想要的是一本书。显然，句子是强调句型。

定语从句中的关系词在从句中还要做某种成分，因而从句成分不完整；而结果状语从句中的连接词不作句子任何成分，因此句子成分完整。如(from )： It is such an interesting book as we all like.它是我们大家都喜欢的如此有趣的书。(定语从句)

It is such an interesting book that we all like it.它是一本如此有趣的书，我么大家都喜欢它。(结果状语从句)比较：It is such an interesting book that we all like.强调句型。意思是：我们大家都喜欢的是一本如此有趣的书(from )。
