名词性从句
从句有名词性从句、定语从句和状语从句三大类。
名词性从句又可分为宾语从句、表语从句、主语从句及同位语从句，因为从句的在这个句子中的功用相当于名词；
定语从句有称为形容词性从句，因为从句功能相当于形容词；
而状语从句则称为副词性从句，因为从句功能相当于副词。
什么是名词性从句?
在英语的句子结构中，本来该由名词充当的主语、宾语、表语和同位语，由一个句子来充当,这个句子就叫名词性从句。
宾语从句( The Object Clause)
表语从句( The Predicative Clause)
主语从句( The Subject Clause)
同位语从句( The Appositive Clause)
同位语从句
一．定义
在句中用作同位语的从句叫做同位语从句。
从句作同位语表示与之同位的名词(短语)的实际内容，它的作用相当于名词，对前面的名词(短语)加以补充说明或进一步解释，相当于一个表语从句，它们之间的关系是同位关系，即主表关系。
补充：
同位语定义：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。
同位语类型：
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 was a clone?”但是现在他们不得不思考这样的问题：“多莉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。
二．同位语从句的先行词
可以跟同位语从句的名词通常有news，idea，fact，promise，question，doubt，thought，hope，message，suggestion，words（消息），possibility 等。
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。
How did the cheats explain the fact that the Emperor didn't feel the new clothes in him? 皇帝觉得身上并没有穿上新衣，对这个问题骗子是怎样解释的?
代词it可用作同位语从句的先行词。这个it常放在某些动词或短语动词后作宾语，同时兼作其后that同位语从句的先行词。
I owe it to you that I am still alive. 幸亏你，我现在还活着。
有的语法学家把先行词it后的that从句看作是动词或介词的真正宾语。一般认为，这种it后的that 从句应看作it的同位语，因为它相当于“主语+be+表语”结构。
You must see to it that the children don't catch cold.(=You must see to it, and It is that the children don't catch cold.)你要当心，别让孩子们着凉了。
三．同位语从句在句子中的位置
1.一般情况下同位语从句跟在某些名词(如news，idea，fact，promise，hope，message等)的后面，用以说明该名词所表达的具体内容。
I’ve come from Mr Wang with a message that he won’t be able to see you this afternoon.我从王先生那边得知一个消息，他说他今天下午不能来看你了。
2.有时同位语从句可以不紧跟在它所说明的名词后，而被别的词语隔开，在语法上叫做分隔式同位语从句。
The thought came to her that maybe she had left the door open when she left home.她突然想起可能在她离开家时没把门关上。
四．引导词
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1】在某些名词(如demand, wish, suggestion, resolution等)后面的同位语从句要用虚拟语气
There was a suggestion that Brown should be dropped from the team. 有一项建议是布朗应该离队。
【注意2】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。
【注意】whether 可引导同位语从句，但if不能引导同位语从句。
3.连接代词what, who, whom, whose, which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).I have no idea which wine is best—it’s a matter of personal taste.我不知道哪种酒最好，这是个人口味的问题。（which作定语）
3).The question who will take his place is still not clear. （who作主语）
4. 连接副词引导同位语从句连接副词when, where, how, why
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。
五．同位语从句的语气
在suggestion，advice，request，order等意为“建议；命令；要求”的名词后，同位语从句中的谓语动词通常用“should +动词原形”的虚拟语气结构，句中的should可以省略。
Our teacher gave us some advice how we(should)use the computer.老师给我们提出了一些如何使用电脑的建议。
六．同位语从句和定语从句的区别
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. 引导词的不同
what, how, if, whatever 等可引导名词性从句，但不引导定语从句。
3. 引导词的功能上的不同
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。
试区分以下句子
例1：
Do you know the fact that he stole the car?
Do you know the fact that they were talking about?
例2：
The news that the plane would take off on time made everybody happy. The news that is spreading around the airport is that a heavy storm is coming.
4. 被修饰词语的区别
同位语从句所修饰的名词比较有限，通常有hope, wish, idea, news, fact, promise, opinion, suggestion, truth等，而定语从句所修饰的名词则非常广泛。另外，when和where 引导定语从句时，通常只修饰表示时间和地点的名词，而它们引导同位语从句时却不一定；又如
why引导定语从句，它通常只修饰名词the reason，而它引导同位语从句时则不一定：
I have no idea when they will come . 我不知道他们什么时候来。(同位语从句)
I’ll never forget the days when I lived there.. 我永远不会忘记我住在那儿的日子。(定语从句）
例1：
1）Information has been put forward ____ more middle school graduates will be admitted into universities.
A. while
B. that
C. when
D. as
析：答案为B。more middle school graduates will be admitted into universities是Information的内容，且Information不在从句中作成分，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. what
B. that
C. when
D. as
析：答案为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：
1）She heard a terrible noise,____ brought her heart into her mouth.(MET91)
A. it
B. which
C. this
D. that
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：
2）I can't stand the terrible noise ____ she is crying loudly.
A. it
B. which
C. this
D. that
析：答案为D。she is crying loudly是the terrible noise的内容，且the terrible noise不在从句中作成分，所以该句为同位语从句。

一、同位语从句的引导词 引导同位语从句的词语通常有连词that，whether，连接代词和连接副词等。 1. 由that引导 We heard the news that our team had won. 我们听到消息说我们队赢了。 They were worried over the fact that you were sick. 他们为你生病发愁。 The news that we are having a holiday tomorrow is not true. 明天放假的消息不实。 I’ve come to the conclusion that it was unwise to do that. 我得出结论这样做是不明智的。 The fact that the money has gone does not mean it was stolen. 那笔钱不见了这一事实并不意味着是被偷了。 He referred to Copernicus’ statement that the earth moves round the sun.他提到了哥白尼关于地球绕太阳转的说法。 【注意1】在某些名词(如demand, wish, suggestion, resolution等)后面的同位语从句要用虚拟语气。如： They were faced with the demand that this tax be abolished. 他们面对废除这个税的要求。 They expressed the wish that she accept the award. 他们表示希望她接受这笔奖金。 There was a suggestion that Brown should be dropped from the team. 有一项建议是布朗应该离队。 The suggestion that the new rule be adopted came from the chairman. 采纳新规则的建议是主席提出的。 The resolution that women be allowed to join the society was carried. 允许妇女参加这个协会的决议通过了。 I can understand their eagerness that you should be the main speaker. 我理解他们希望你作主要发言人的殷切心情。 【注意2】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。如： He gabbed 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. 由whether引导 There is some doubt whether he will come. 他是否会来还不一定。 Answer my question whether you are coming. 你回答我的问题：你来不来。 The question whether it is right or wrong depends on the result. 这个是对还是错要看结果。 We are not investigating the question whether he is trustworthy. 我们不是在调查他是否可以信任的问题。 【注意】whether 可引导同位语从句，但if不能引导同位语从句。
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 was a 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）
what引导名词性从句的五种用法 一、用法归纳 1. 表示“……的东西或事情”： They’ve done what they can to help her. 他们已经尽力帮助了她。 He saves what he earns. 他赚多少，积蓄多少。 What Mary is is the secretary. 玛丽的职务是秘书。 2. 表示“……的人或的样子”： He is no longer what he was. 他已经不是以前的那个样子。 He is what is generally called a traitor. 他就是人们通常所说的叛徒。 Who is it that has made Fred what he is now? 是谁把弗雷德培养成现在这个样子的？ 3. 表示“……的数量或数目”： Our income is now double what it was ten years ago. 我们现在的收入是10年前的两倍。 The number of the students in our school is ten times what it was before liberation. 现在我校学生的数量是解放前的10倍。 4. 表示“……的时间”： After what seemed like hours he came out with a bitter smile. 似乎过了几个小时他才苦笑着出来。 The young girl was too frightened to speak, standing there for what seemed like hours. 小女孩吓得不敢说话，在那儿站了几个小时。 5. 表示“……的地方”： This is what they call Salt Lake City. 这就是他们称为盐湖城的地方。 In 1492, Columbus reached what is now called America. 1492年哥伦布到达了现在所称的美洲大陆。 二、用法说明 (1) 这样用的what相当于“先行词+关系代词”，所以其前不能有先行词： 你喜欢什么就拿什么吧。 正：You can have what you like. / You can have everything (that) you like. 误：You can have everything what you like. (2) 有时what 可用作限定词，其后修饰一个名词： I gave him what books I had. 我把我所有的书都给他了。 He gave me what money he had about him. 他把身边带有的钱全给了我。 (3) What 后的名词可以是复数名词或不可数名词，但通常不能是单数可数名词： 误：I gave him what book I had.
一、在名词从句中连接词which 有两种词性, 常用来引导宾语从句： 1. [连接代词] 哪个 1）用作从句的主语，如： He wanted to know which was on the table. 他想知道哪一个在桌子上。 2) 用作从句的宾语，如： He asked me which I liked best. 他问我最喜欢哪一个。 2. [连接形容词]放在名词前作定语，表示“哪个XX，哪些XX”，如： Do you wnow Which country is the largest? 你知道哪国家一个最大? Could tell me which children made him still more angry. 能告诉我那些 孩子使他更加生气了。 二、which 除引导上述宾语从句外，还可以引导主语从句和表语从句。 1. 主语从句(常用形式主语it) It was clear which children made him still more angry. 显而易见那些孩子使他更加生气了。 It is known to us which he liked best. 众所周知他最喜欢哪一个。 2. 表语从句 That was which children made him still more angry. 那就是那些孩子使他更加生气了。 This is which he liked best. 这就是他最喜欢哪一个。 三、which 与what 的区别 用在名词从句中，which 意思是“哪一个/那一些”，what 意思是“所...的”，后者等于“先行词+关系代词”，如你的补充问题就需要选择what： It's quite different from what I read last month. = It's quite different from (the one that) I read last month. 这本书与我上周所读过的那一本区别很大。 1.that在所有名词性从句中无成分无意义。 2.which强调哪一个，有一个选择的范围。 从句中from后边缺宾语，所以要选择的是宾语从句的引导词，首先that引导宾语从句时，不做介词宾语（除了in,except,but) 其次read后边缺宾语，也就是从句中缺成分，参见上面第一条，所以排除that.B选项which指哪一个，这里
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 me the 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 requires consideration. （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 diamond ring. （4）后面常跟同位语的词有：doubt,fact,hope,idea,message,news,possibility,promise,question,suggestion,truth,thoug ht,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。（定语从句） The fact that she hadn’t said anything surprised us all. 她一言不发的事实让我们每一个人都很惊讶。（同位语从句） （2）在句中所起的语法作用不同：引导定语从句的that是关系代词，它的作用是连接主句和从句，并代表先行词在从句中充当句子成分，而且that作宾语时可省略， 指物时，可以用which代替。引导同位语从句的that是连词，只起连接主句和从 句的作用，它不充当任何成分，不能省略，也不可被which代替。如: We expressed the hope that Mr and Mrs Smith would come to visit China the next year. 我们表达了希望史密斯夫妇第二年到中国来访的愿望。（同位语从句） The news(that/which)we heard spread all over the city. 我们所听到的消息传遍了整个城市。（定语从句） （3）所修饰的词不尽相同：同位语从句所修饰的名词数量有限，往往是含有某种信息的词，如：message,news,fact,hope,desire,problem,idea,suggestion,advice,questtion, order,belief,doubt,fear,truth,throught等，而定语从句修饰的先行词无此限制。 （4）wh-引导词引导同位语从句时，有其本身的疑问含义；引导定语从句时则没有疑问的意思。如；
名词性从句归纳 一、名词性从句概说、结构与功能 名词性从句是起名词作用的从句，其功能相当于名词词组，在复合句中可作主语、宾语、表语和同位语。与之对应的名词性从句分别为主语从句、宾语从句、表语从句和同位语从句。 二、主语从句 1、主语从句的类别 ●以从属连词that 引导的主语从句。（从句位于句首，that通常不省略） → That she will come to the conference has excited every one of us. ●以从属连词whether 引导的主语从句。（从句置于句首时一般不用if来代替whether） → Whether we’ll go outing depends on the weath er. ●以连接代词（what, whatever, who, whoever, which, whichever等词）引导的主语从句。 → Whoever will be in charge of the project hasn’t been decided yet. 【注】what 与that在引导主语从句时，what 不但起连接作用，而且还有具体意义，意为“所…的”，相当于the things that结构；而that则无词义。即如果从句中不缺少主语或宾语时，选择that，否则用what。 ●以连接副词（when，where, how, why 等词）引导的主语从句. → When the new road is open to traffic has not been made clear. 2、用it 作形式主语的主语从句 注：以下几种特殊情况必须用it作形式主语： ⑴ It is + adj. + that 从句 常见的形容词有：necessary，right，likely，wrong，important，certain，clear，obvious，strange 等。 → It is likely that there will be a snowstorm tomorrow. ⑵ It is + noun + that 从句 常接这种句型的名词有：a pity, a shame, good news, a fact, an honor, a wonder, no wonder 等。 → It is a pity that you didn’t attend the lecture [讲座] yesterday. ⑶It is + 过去分词
同位语从句用法小结 在复合句中充当同位语的名词性从句称为同位语从句。在使用同位语从句时，应注意以下五个方面： 一、常见带有同位语从句的抽象名词 advice，announcement，argument，belief，claim（声明、主张），conclusion，decision，evidence，explanation，fact，feeling，hope，idea，impression，information，knowledge，message，news，opinion，order，probability，promise，proposal，remark，reply，report，saying，statement（声明、陈述），suggestion，thought，warning，wish，word 二、同位语从句连接词的选用 在英语中，引导同位语从句的词通常有连词（that，whether），连接代词(what ,who等)连接副词（how，when，where）。 The question who should do the work requires consideration. I have no idea what he is doing now.。 There was little hope that he would survive. 他幸存的希望很小。 He hasn't made the decision whether he will go there. It's a question how he did it. 那是一个他如何做了此事的问题 注：在名词doubt“怀疑”后的同位语从句用whether连接；在no doubt“不怀疑”之后的同位语从句用that连接。例如： There is no doubt that Tom will keep his promise. 三、同位语从句在句中的位置 1. 一般情况下同位语从句跟在某些名词（如news，idea，fact，promise，hope，message等）的后面，用以说明该名词所表达的具体内容。例如： The news that our women volleyball team had won the championship encouraged us all greatly. 2. 有时同位语从句可以不紧跟在它所说明的名词后，而被别的词语隔开，在语法上叫做分隔式同位语从句。例如： The thought came to her that maybe she had left the door open when she left home.
同位语从句 一．同位语 同位语：跟在名词或代词后，与之表达同一内容；通常由名词、名词性短语等担任。 （A=B：两项所指相同） e.g 我知道奥巴马，美国的总统。 I know Obama, the president of United States. （Obama与the president of US同一个人）我们应该从过去当中学习，它是现在的一面镜子和将来的希望。 We should learn from the past, the mirror of the present and the hope of the future. The future belongs to you, young people. 未来是属于你们年轻人的。(you=young people) (实质是句中两个成分相等) 二．同位语从句 1.（1）概念：由一个句子来充当同位语。 e.g 我知道这个事实，奥巴马是美国的总统。 I know the fact that Obama is the president of United States. (the fact就是指的是奥巴马是美国总统) We should learn from the truth that the past is the mirror of the present and the hope of the future. （2）与从句同位的名词通常为抽象名词： fact, truth, Idea, thought, belief, hope, doubt, rumour, question, answer, reply, news, , order (有些抽象名词本身带有“疑问”的含义，如question, doubt) 2. 构成： （------先造3个简单的句子，He is a student.(陈述句) Is he a student?（一般疑问句）Who is a student?(特殊疑问句) 同位语从句(连词)不是与前面的抽象名词有关，连词取决于后面从句是什么样的形式； （I know the fact he is a student. ） （1）如果从句是陈述句，连词用that e.g I know the fact that he is a student. 我听到了这个消息，他离开了我们。 I heard the news that he left us. The general gave the order that the soldiers should cross the river at once. 将军下达了命令战士们应该立即过河。 We are delighted at the news that we are going to spend our summer vacation in Hawaii. 我们非常高兴听到这个消息，我们将在夏威夷度过我们的暑假。 The fact that he had not said anything surprised everybody． 他什么都没说，这个事实让大家很吃惊。 结论：that在从句中不做成分，并且没有含义 （2）如果从句是一般疑问句，连词用whether, 再把一般疑问句变陈述句语序
名词性从句用法归纳Mar 3, 2011 名词性从句包括主语从句，宾语从句，表语从句和同位语从句。它们的作用相当于名词，因此为名词性从句。 一. 主语从句 引导词：连词that, whether; 连接代词who / whoever，what / whatever，which ； 连接副词when, where, how, why。 1.That 1) That computers have changed our life is clear to everyone. = It’s clear to everyone that computers have changed our life. 2) That children must go to school is accepted by us all. = It’s accepted by us all that children must go to school. 3) That you are from Tangshan can be judged from your accent. = It can be judged from your accent that you are from Tangshan. 结论：that 无含义, 不做成分。 2. what 1）What I can’t understand is why he is often absent from school. 2）What parents say and do has a life-long effect on their children.

同位语从句讲解及习题 一、理解同位语从句的含义，把握同位语从句的实质 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等抽象名词后面，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.他们比赛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，准确把握同位语从句 1.如同位语从句意义完整，应用that引导同位语从句。（即that 不充当任何成分，只起连接作用，不可省略） 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。

英语同位语从句用法详解 在复合句中充当同位语的名词性从句称为同位语从句。同位语从句是名词性从句（主语从句、表语从句、宾语从句、同位语从句）中的主要从句之一，也是中学英语学习中的重点语法知识点之一。在使用同位语从句时，应注意以下五个方面： 一、同位语从句在句中的位置 1. 一般情况下同位语从句跟在某些名词（如news，idea，fact，promise，hope，message 等）的后面，用以说明该名词所表达的具体内容。例如： The news that our women volleyball team had won the championship encouraged us all greatly. 我们女排赢得冠军的消息大大地鼓舞了我们所有人。 I've come from Mr Wang with a message that he won't be able to see you this afternoon. 我从王先生那边得知一个消息，他说他今天下午不能来看你了。 2. 有时同位语从句可以不紧跟在它所说明的名词后，而被别的词语隔开，在语法上叫做分隔式同位语从句。例如： The thought came to her that maybe she had left the door open when she left home. 她突然想起可能在她离开家时没把门关上。 The story goes that he failed in the College Entrance Examinations again. 据说他高考又落榜了。 二、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。例如： Where did you get the idea that I could not come？你在哪儿听说我不能来？ Give me your promise that you will come to our party this evening. 答应我，你今天晚上要来参加我们的晚会。 Word came that China launched its first manned spaceship on Oct 15，2003. 消息传来，中国于2003年10月15日首次成功发射了载人飞船。 三、同位语从句连接词的选用 在英语中，引导同位语从句的词通常有连词（that，who，whether），连接副词（how，when，where）等。例如：

A. where does he live B. where he lives C. he where lives D. he lives where 【答案】 B 【解析】【分析】句意:----让我们把他送回家。你知道他住在哪里吗?----我不知道。宾语从句就是一个句子作动词或介词的宾语。宾语从句由特殊疑问句变来就用原来的疑问词作引导。在宾语从句中只能使用陈述句语序，不能用疑问句语序。所以选B。 2． is clear to the members of the committee is that the President will not give in to their demands. A. Who B. It C. As D. What 【答案】 D 【解析】【分析】句意：委员会成员清楚的是，总统不会向他们的要求让步。that the President will not give in to their demands.这个句子作表语； is clear to the members of the committee这是主语从句，这里缺少主语从句的连接词，并且连接词在句中作主语，it是代词，不是了；连接词，故排除B；as作主语时，是在定语从句中，故排除C；who指人，根据表语指的事情，不是人，故排除A；what在主语从句中可以作主语或宾语，指事，符合句意，故选D。 【点评】考查名词性从句，本题涉及what引导的主语从句。 3． is even more important is the earth cooled down, water began to appear on its surface. A. When; that; when B. What; whether; as C. What; that; as D. lt; whether; as 【答案】 C 【解析】【分析】这题考查从句的用法，第一空填what引导主语从句，在主语从句中what做主语，第二空填that引导表语从句，在表语从句中，as是引导时间状语从句，句意是：甚至更重要的是：随着地球的冷却，水开始出现在表面。选C。 4．In the past decade, our education system too much on grades.
