英语中同位语的用法
一、同位语从句的定义和特点
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
引导同位语从句的连接词
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。
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.
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。

A. which
B. that
C. what
D. whether
2. A warm thought suddenly came to me ____ I might use the pocket money to buy some flowers for my mother's birthday．

英语同位语用法的六种易错点
英语同位语用法的六种易错点 当两个指同一人或事物的句子成分放在同等位置时，若其中一个句子成分是用于说明或解释另一个句子成分的，那么用于起说明或解释作用的句子成分就叫做另一成分的同位语。如： Laura Myers, a BBC reporter, asked for an interview. 劳拉·迈尔，BBC的记者，要求采访。 Influenza, a common disease, has no cure. 流行性感冒是一种常见病，无特效药。 Mary, one of the most intelligent girls I know, is planni ng to attend the university. 玛丽是我所认识的最聪敏的姑娘之一，她正准备上大学。 Who is that man, the first in the front row? 前排第一个人是谁?

初中英语――祈使句 祈使句指的是表示命令、请求、建议或劝告的句子。其主语you常省略，谓语动词用原形，句末用感叹号或句号，读降调。 1. 肯定的祈使句 （1）动词原形+其他 Stand up, please. = Please stand up. 请起立。 （2）Be + n./adj. Be a good boy! 要做一个好孩子! Be careful! = Look out! = Take care! 小心/ 当心！（3）Let + 宾语+ 动词原形+ 其它成分 Let me help you. 让我来帮你。Let’s go to school together. 咱们一起上学去吧。 2. 否定的祈使句 (1) Don't + 动词原形 Don't stand up. 别站起来。 Don't be careless. 别粗心。 Don't let them play with fire. 别让他们玩火。 （2）Let型的否定式有两种:“Don't + let + 宾语+ 动词原形+ 其它成分”和“Let + 宾语+ not + 动词原形+ 其它成分”。 Don't let him go. / Let him not go. 别让他走。 Let them not play with fire. 别让他们玩火。 （3）no开头,用来表示禁止性的祈使句。 No smoking! 禁止吸烟!No fishing! 禁止钓鱼! 3. 祈使句的强调形式，通常在肯定祈使句式前加上助动词Do。 例如：Do shut up! 快住口！ 4. 祈使句的回答祈使句的动作通常是表示将来发生的动作，所以回答祈使句时，一般用 will或won’t。 在回答具有否定意义的祈使句时，要注意两点： 1)形式一致(即Yes与will保持一致；No与won’t保持一致) 2) 意思相反(即Yes是“不”的意思；No是“是”的意思)。 在回答时，要注意分析上下文语境中所提供的条件。 如：--- Don’t go out, please.

I have to meet my brother at the airport. 不行，我得去机场接我弟弟。 5. 祈使句的反意疑问句 (1) 肯定祈使句的反意疑问句反问部分用will you 或won't you。 Please open the door, will/ won’t you? 请把门打开，好吗？ (2) 否定祈使句的反意疑问句反问部分只用will you。 Don't be late again, will you? 别再迟到了，行不行？ (3) 以let's开头的祈使句反意疑问句反问部分用shall we。 Let's turn on the TV, shall we? 我们把电视打开，好吗？ <特别注意> 只有以let's开头的祈使句的反意疑问句的反问部分才用shall we，而let us 开头的祈使句的反意疑问句的反问部分应为will you或won't you.如：Let us stay here, will/ won't you? 请（你）让我们留在这好吗？
英语同位语从句用法详解
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：
高考英语同位语从句考点
高考英语最可能考的同位语从句 英语中有两类从句所修饰的名词可以叫“先行词”，一类是定语从句，一类是同位语从句。同学们知道，定语从句所修饰的先行词数量很多，单是指人和指物的名词就有千千万万个，但英语中的同位语从句则不同，它所修饰的先行词非常有限，中学英语中最常用的可能只有几十个，并且高考可能重点的考查只有十几个： 1. chance 可能性 chance后接that引导的同位语从句，表示某事发生的可能性。如： I think that there is every chance that you will succeed. Do you think there’s any chance that you could get a job in Paris 2. doubt 怀疑 doubt后接that引导的同位语从句，表示对某事的怀疑。如： There is no doubt that the world is getting warmer. There’s no doubt that one day a cure will be found. 3. fact 事实 fact后接that引导的同位语从句，表示某个事实的具体内容。如： The fact that something is cheap doesn’t necessarily mean it’s of low quality. The fact that the money has gone does not mean it was stolen. In spite of the fact that hotel prices have risen sharply, the number of tourists is as great as ever. 4. evidence证据 evidence后接that引导的同位语从句，表示某个证据的具体内容。如： Do you have evidence that this treatment works Is there any scientific evidence that a person's character is reflected in their handwriting 5. hope希望 hope后接that引导的同位语从句，表示希望的具体内容。如： Is there any hope that they will be home in time The President has expressed the hope that relations will improve. 6. idea 想法 idea后接that引导的同位语从句，表示某个想法的具体内容。如： It’s based on the idea that all people are created equal. Where did you get the idea that she doesn’t like you

我们中国人民是勤劳勇敢的。 He is interested in sports, especially ball games. 他喜欢运动,特别是球类运动。 [编辑本段] 同位语从句 先行词 1．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． ④Th e 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。 2．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。

高中-同位语从句详细讲解与练习(附答案)
同位语从句讲义 1．定义：用作同位语的从句叫做同位语从句。 2.用法：同位语从句的先行词多为fact, news, idea, thought, question, reply, report, remark等，关联词多用从属连词。如： They were all very much worried over the fact that you were sick.对你生病这件事，他们都很焦虑。 Where did you get the idea that I could not come?你在哪儿听说我不能来？ Early in the day came the news that Germany had declared war on Russia.德国已对俄国宣战的消息一大早就传来了。 注：同位语从句偶尔由从属连词whether引导。如：I have no idea whether he’ll come or not.我不知道他是否来。 连接代词who, which, what和连接副词where,when, why, how亦可引导同位语从句。 The question who should do the work requires consideration.谁该干这项工作，这个问题需要考虑。 W e 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。 It is a question how he did it.那是一个他如何做了此事的问题。 1．that引导的同位语从句与定语从句之区别? that引导的同位语从句 that引导的定语从句 句法功能上 that只起连接从句的作用，无意义。 在从句中不充当句子成分。 不可省。 that替代先行词在从句中不仅起连接作用， 还充当一个句子成分。如在从句中作 动词的宾语时可省略。 意义上 从句是被修饰名词的内容。 从句起限定作用，是定语 如： The news that Mr. Li will be our new English teacher is true. (同位语从句，that不可省) 李先生将是我们的新英语老师这个消息是真的。The news (that) he told me yesterday is true. (定语从句，that在从句中作的宾语，可省)他昨天告诉我的消息是真的。 2．一些表示“建议、命令、要求”的名词后所跟的同位语从句中，谓语动词用虚拟语气should+动词原形表示。should可省。如：This is our only request that this (should) be settled as soon as possible.这就是我们唯一的请求：尽快解决这个问题。 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，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。 详细信息一个名词(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。 同位语从句用法同位语部分是个句子,就是同位语从句,这种用法比较"固定" 一、在复合句中用作同位语的从句叫同位语从句。它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。 二、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。 三、英语中引导同位语从句的词通有连词that，whether，连接副词how,when,where等。（注：if,which 不能引导同位语从句。） 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。
