同位语从句讲解及练习含答案
同位语从句讲解与训练一、同位语的概述1. 同位语的定义：一个名词或代词后面有时可跟一名词(或其它形式)，对它作进一步的修饰,限定或说明，说明它是谁，是什么，当两个词或词组在一个句子中具有相同的语法地位而且描述相同的人或事物时，我们称它们为同位语。
同位语与被它限定的词的格要一致,并常常紧挨在一起。
2. 同位语的分类：同位语分限制性和非限制性两种。
限制性同位语和前面的词关系比较密切，之间不能停顿；非限制性同位语与前面的词关系比较疏散，常用逗号隔开。
例如：③Mickey Mouse first appeared in the cartoon Steamboat Willie.米老鼠首次出现在卡通片《威利号汽船》中。
Steamboat Willie就是cartoon的同位语，关系紧密。
④Walt Disney, an rich and successful businessman, created the famous cartoon character----Mickney Mouse. 瓦尔特迪士尼，一个富有而成功的商人，创造出了这个著名的卡通形象----米老鼠。
an rich and successful man 是主语Walt Disney的同位语，句子中有没有它，无所谓，不影响理解。
而且“瓦尔特迪士尼”是个“富有而成功的商人”，反过来，“一个富有而成功的商人”可不一定就是“瓦尔特迪士尼”。
3. 同位语的形式：(1)名词用作同位语时最多：①This is Mr．Brown，our Spanish teacher．这是我们的西班牙语老师布朗先生。
②“Leave it to me，”said Lao He，the man on night duty．值夜班的人老何说：“这事交给我。
”③You girls may take those seats over there．你们姑娘们可以坐在那边的座位上。
同位语从句重难点解析及习题
同位语从句一、同位语从句概述同位语从句是用以解释说明某一名词内容的从句，常见的可以被同位语从句修饰的名词有：belief，chance,doubt,hope,idea,news,opinion，thought，promise等。
引导同位语从句的词有连词that，whether和副词how，when,where等。
二、同位语从句点拨（1）同位语从句是意义完整的陈述句时，用连词that引导。
注:that在从句中不充当任何成分,只起连接作用,通常不省略.如：I got the news that he would come to see methe next week。
（2）同位语从句是疑问句时，应根据语境选用who，when ，where，how，whether（不能用if）等词来引导.如：The question who is the best for the job requiresconsideration.（3）分隔式同位语从句：当主句的谓语较短，而同位语从句较长时,为了使句子保持平衡，常把同位语从句后置。
如:An idea came to him that he could buy her a diamondring.（4）后面常跟同位语的词有:doubt,fact,hope,idea,message，news,possibility，promise，question，suggestion，truth，thought,warning,wish等。
注:advice，order，suggestion等词表示建议、命令的词后的同位语从句中的谓语动词须用(should）+动词原形。
如：He made the suggestion that the meeting(should）be put off。
三、同位语从句与定语从句的区别（1）所表达的内容不同：同位语从句和定语从句一般是放在某一名词后面,但同位语从句是对该名词的解释和说明,而定语从句是对该名词的修饰,说明它的性质特征.如：The fact that he presented was a strong proof.他所提供的事实是一个强有力的证据。

同位语从句
三、把握同位语从句和定语从句的区别，明确同位语从句和 相似从句的界限 同位语从句和定语从句相似，都放在某一名词或代词后 面，但同位语从句不同于定语从句。同位语从句对名词加以补 充说明，是名词全部内容的体现，且名词和同位语从句的引导 词均不在从句中作成分；定语从句说明先行词的性质与特征， 与先行词是修饰与被修饰的关系，且名词和定语从句的引导词 均在从句中作成分。 区分时可以在先行词与与从句之间加一个系动词be,使之构成 一个新句子，如果句子通顺且符合逻辑，则为同位语从句，反 之，则为定语从句。 如：The report that he was going to resign was false. 因为the report was that he was going to resign 句意通顺， 所以，that he was going to resign 是同位语从句。
析：答案为B。分析语境含义、句子结构和句 子成分可知，该句为非限制性定语从句，先 行词为a terrible noise，且它在从句中作主语。 应将该句区别于：
I can't stand the terrible noise ____ she is crying loudly. A. it B. which C. this D. that
析：the soldiers should cross the river at once是the order的全部内容，且意 义完整，因此应用that引导同位语从句。 2.如同位语从句意义不完整，需增加“是否”的含义，应用whether引导同位 语从句。（if不能引导同位语从句） 例：We'll discuss the problem whether the sports meeting will be held on time.我们将讨论运动会是否会如期举行的问题。 析：the sports meeting will be held on time意义不完整，应加“是否” 的含义才能表达the problem的全部内容，因此应用whether引导同位语从句。 3.如同位语从句意义不完整，需增加"什么时候"、"什么地点"、"什么方式"等 含义，应用when, where, how等词引导同位语从句。 例1：I have no idea when he will be back. 析：he will be back意义不完整，应加“什么时候”的含义才能表达idea 的全部内容，因此应用when引导同位语从句。 例2：I have no impression how he went home, perhaps by bike. 析：he went home意义不完整，应加“如何”的含义才能表达impression的 全部内容，因此应用how引导同位语从句。 4.当主句的谓语较短，而同位语从句较长时，同位语从句常后置。 如：The thought came to him that maybe the enemy had fled the city

高中英语同位语从句讲解及练习之马矢奏春创作同位语从句讲义及练习一、理解同位语从句的含义,掌控同位语从句的实质在主从复合句中作同位语的从句称为同位语从句.同位语从句一般用that, whether,what, which, who, when, where, why, how 等词引导,常放在fact, news, idea, truth, hope, problem, information, wish,promise, answer, evidence, report, explanation, suggestion, conclusion等笼统名词后面,说明该名词的具体内容.换言之,同位语从句和所修饰的名词在内容上为同一关系,对其内容作进一步说明.例：The news that they had won the game soon spread over the whole school.他们角逐获胜的消息很快传遍了整个学校.析：they had won the game说明The news的全部内容,因此该句为同位语从句.二、正确运用同位语从句的引导词,准确掌控同位语从句1.如同位语从句意义完整,应用that引导同位语从句.（即that 不充任任何成份,只起连接作用,不成省略）例：The general gave the order that the soldiers should cross the river at once.将军下达了战士们立即过河的命令.析：the soldiers should cross the river at once是the order的全部内容,且意义完整,因此应用that引导同位语从句.2.如同位语从句意义不完整,需增加"是否"的含义,应用whether引导同位语从句.（if不能引导同位语从句）例：We'll discuss the problem whether the sports meeting will be held on time.我们将讨论运动会是否会如期举行的问题.析：the sports meeting will be held on time意义不完整,应加"是否"的含义才华表达the problem的全部内容,因此应用whether引导同位语从句.3.如同位语从句意义不完整,需增加"什么时候"、"什么地址"、"什么方式"等含义,应用when, where, how等词引导同位语从句.例1：I have no idea when he will be back.析：he will be back意义不完整,应加"什么时候"的含义才华表达idea的全部内容,因此应用when引导同位语从句.例2：I have no impression how he went home, perhaps by bike.析：he went home意义不完整,应加"如何"的含义才华表达impression的全部内容,因此应用how引导同位语从句.4.当主句的谓语较短,而同位语从句较长时,同位语从句常后置.如：The thought came to him that maybe the enemy had fled the city.三、掌控同位语从句和定语从句的区别,明确同位语从句和相似从句的界限同位语从句和定语从句相似,都放在某一名词或代词后面,但同位语从句分歧于定语从句.同位语从句对名词加以弥补说明,是名词全部内容的体现,且名词和同位语从句的引导词均不在从句中作成份；定语从句说明先行词的性质与特征,与先行词是修饰与被修饰的关系,且名词和定语从句的引导词均在从句中作成份.区分时可以在先行词与与从句之间加一个系动词be,使之构成一个新句子,如果句子通顺且符合逻辑,则为同位语从句,反之,则为定语从句.如：The report that he was going to resign was false.因为the report was that he was going to resign 句意通顺,所以,that he was going to resign 是同位语从句.例1：1）Information has been put forward ____ more middle school graduates will be admitted into universities.A. whileB. thatC. whenD. as析：谜底为 B.more middle school graduates will be admitted into universities是Information的内容,且Information不在从句中作成份,所以该句为同位语从句.应将该句区别于：2）It is said that more middle school graduates will be admitted into universities,this is the information ____ has been put forward.A. whatB. thatC. whenD. as析：谜底为B.that has been put forward为information 的修饰性定语,且information在从句中作主语,所以该句为定语从句.例2：She heard a terrible noise,____ brought her heart into her mouth.(MET91)A. itB. whichC. thisD. that析：谜底为B.分析语境含义、句子结构和句子成份可知,该句为非限制性定语从句,先行词为a terrible noise,且它在从句中作主语.应将该句区别于：I can't stand the terrible noise ____ she is crying loudly.A. itB. whichC. thisD. that析：谜底为D.she is crying loudly是the terrible noise 的内容,且the terrible noise不在从句中作成份,所以该句为同位语从句.巩固性练习：1.

(同位语从句)We are not looking into the question whether he is worth trusting.(同位语从句)Word came that he had been abroad. (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)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)His mother did all she could to help him with his study.他妈妈尽她的最年夜努力帮手他的学习?(定语从句,代词all作先行词?)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笼统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. 我们队赢了那场角逐的消息是真的?(同位语从句,弥补说明news究竟是一个什么消息?)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?)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,弥补说明promise究竟是一个什么诺言?)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,promise在从句中作pleased的主语?)3. 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)I have no idea what has happened to him. 我不知道他发生了什么事?(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取代),而且作宾语时经常省略?that在同位语从句中仅起连接作用,不充任任何成份,而且不能省略,也不能用which来取代?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另外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手另外几个小组?(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?)。

同位语从句◆◆◆辨认同位语从句在复合句中充当同位语的名词性从句称为同位语从句。
一个名词（或其它形式）对另一个名词或代词进行修饰，限定或说明，这个名词（或其它形式）就是同位语。
同位语与被它限定的词的格要一致，并常常紧挨在一起。
1. 名词作同位语Mr. Wang, my child’s teacher, will be visiting us on Tuesday.王先生，我孩子的老师，星期二要来看我们。
2. 短语作同位语I, the oldest girl in the family, always had to care for the other children.我，作为家里最大的女孩，老得照料家中的其他孩子。
3. 直接引语作同位语But now the question comes to their minds, “Did she die young because she wasa clone”但是现在他们不得不思考这样的问题：“多利早死是因为它是一只克隆羊吗”4. 句子作同位语The girls were surprised at the fact that ocean ships can sail up the Great lakes.巨大的海轮可以开到五大湖，让表姐妹俩感到吃惊。
$◆◆◆同位语从句用法一、同位语从句一般跟在某些名词后面，用以说明该名词表示的具体内容。
I heard the news that our team had won．我听到了我们队获胜的消息。
①可以跟同位语从句的抽象名词通常有news，idea，fact，promise，question，doubt，thought，hope，message，suggestion，words（消息），possibility等。
（承诺信息主意是事实；疑问想法与问题；希望消息建议是潜力。
）I’ve come from Mr. Wang with a message that he won’t be able to see you this afternoon．我从王先生那里来，他让我告诉你他今天下午不能来看你了。
②在某些名词表“建议，命令，要求等”(如demand, wish, suggestion, resolution等)后面的同位语从句要用虚拟语气（即should+动词原形；should可省）There was a suggestion that Brown should be dropped from the team. 有一项建议是布朗应该离队。
③同位语从句前名词的数：同位语从句前的名词通常用单数形式，并且往往带有限定词(word除外)加以修饰。
Where did you get the idea that I could not come你在哪儿听说我不能来二、英语中引导同位语从句的词通有连词that，whether,连接代词what，who。
连接副词how, when, where等。
（注：if, which 不能引导同位语从句。
）1. 连词that引导同位语从句（注：引导同位语从句的that不能省略）￥The idea that you can do this work well without thinking is quite wrong.你认为不动脑筋就能做好这件工作的想法是完全错误的。
（作idea的同位语）【注意】引导同位语从句的连词that通常不省略，但在非正式文体中也可以省去。
He grabbed his suitcase and gave the impression he was boarding the Tokyo plane.他拿起了手提箱，给人的印象是他要登上飞往东京的飞机了。
2. 连词whether引导同位语从句（注：if不能引导同位语从句）The question whether we should call in a specialist was answered by the family doctor. 我们是否请专家由家庭医生来定。
He must answer the question whether he agrees to it or not. 他必须回答他是否同意这样一个问题。
3. 其它引导词引导的同位语从句A、连接代词what, who, whom, whose引导同位语从句1).I have no idea what size shoes she wears.我不知道她穿几号的鞋。
（what作定语）2).The question who will take his place is still not clear.（who作主语）B、连接副词when, where, how, why 引导同位语从句】We haven’t yet settled the question where we are going to spend our summer vacation.到哪儿去度暑假，这个问题我们还没有决定。
l have no idea When he will be back．我不知道他什么时候回来。
My question how I shall get in touch with him has not been answered.三、有时同位语从句可以不紧跟在说明的名词后面，而被别的词隔开。
在语法上叫做分隔式同位语从句。
The thought came to him that maybe the enemy had fled the city．他突然想起可能敌人已经逃出城了。
Several years later，word came that Napoleon himself was coming to inspect them．几年以后，有消息传来说拿破仑要亲自视察他们。
◆◆◆定语从句与同位语从句的区别1.意义的不同同位语从句是用于说明所修饰名词的具体内容的，它与被修饰词语通常可以划等号；而定语从句是限制所修饰名词的，它的作用是将所修饰的名词与其他类似的东西区别开来：|We are glad at the news that he will come. 听到他要来这个消息我们很高兴。
(news 的内容就是that he will come，故that引导的是同位语从句)We are glad at the news that he told us. 听到他告诉我们的这个消息我们很高兴。
(that 从句是限制the news的内容的，即我们高兴只是因为他告诉的这个news而不是其他的news，故that从句为定语从句)2.被修饰词语的区别A．定语从句的先行词是名词或代词；而同位语从句的先行词只能是名词，而且仅限于idea，plan，fact，theory，promise，hope，news，doubt，truth，information，suggestion，question， thought，belief，conclusion等少数名词。
例如：①The boy who is playing football is my classmate．②Those who work hard will succeed．③The fact that he had not said anything surprised everybody．④The fact that you are talking about is important．在①句中，划线部分是定语从句，其先行词是名词 boy，它不能用作同位语从句的先行词。
在②句中，划线部分也是定语从句，其先行词是代词those，代词不能用作同位语从句的先行词。
，在③句中，划线部分是同位语从句，其先行词是名词fact，它同样可以用作定语从句的先行词，④句便是一例。
由以上分析可见，同位语从句的先行词一定可以用作定语从句的先行词，但定语从句的先行词不一定能用作同位语从句的先行词。
B．when，where，why引导的定语从句的先行词一定分别是表示时间、地点和原因的名词，而三者引导的同位语从句的先行词则肯定不是表示时间、地点和原因的名词。
例如：①I still remember the day when I first came to Beijing．②I have no idea when she will be back．在①句中，划线部分是when引导的定语从句，其先行词day是表示时间的名词；在②句中，划线部分是when引导的同位语从句，其先行词idea则不是表示时间的名词。
3.引导词的不同定语从句和同位语从句共同的引导词有四个：that，when，where，why。
下面把四个引导词分成两类说明它们在两种从句中的不同用法。
A．引导词that'引导定语从句的that叫做关系代词，它除了起连接作用，还在定语从句中充当一定成分，并且在意义上代表先行词；引导同位语从句的that叫做从属连词，它只起连接作用。
不能省略。
例如：①The news that you told me yesterday was really exciting．②We heard the news that our team had won．在①句中，划线部分是定语从句，that在从句中作宾语，在意义上指代先行词news。
在②句中，划线部分是同位语从句，that没有任何意义，只起连接作用。
that引导同位语从句时，它不充当句子成分，而引导定语从句时，它作为关系代词，要么充当定语从句的主语，要么充当定语从句的宾语。
如上例 that he told us中的that 就充当told的宾语。
B．引导词when，where，why引导定语从句时，它们叫做关系副词，在从句中充当状语，可以转换成"介词＋关系代词"的形式；引导同位语从句时，它们叫做连接副词，在从句中充当状语，但不能转换成"介词＋关系代词"的形式。
例如：①I will never forget the day when I joined the army．]②We have no idea when she was born．在①句中，划线部分是定语从句，when在从句中作状语，它可以转换成on which的形式；在②句中，划线部分是同位语从句， when在从句中充当状语，但不能转换成"介词＋关系代词"的形式。
③This is the house where I lived two years ago．④He put forward to the question where the meeting would be held．在③句中，划线部分是定语从句，where在从句中作状语，它可以转换成in which的形式；在④句中，划线部分是同位语从句， where在从句中充当状语，但不能转换成"介词＋关系代词"的形式。
