人教版高中英语选修8 名师语法：同位语与同位语从句
名师语法：同位语与同位语从句同位语：语法学名词。
指实际语言运用中，两个表示相同的人或事物的语言片段在一起连用时，起解释说明作用的那个语言片段。
比如“周恩来总理是人民热爱的好总理。
”和“我国的首都北京是一座历史名城。
”两个句子中，“总理”和“我国的首都”就是同位语，它们的作用是分别对“周恩来”和“北京”（语法学上叫本位语）加以解释说明。
同位语不同于语法学上的定语，它和本位语之间一定不能加“的”。
同位语是用来对名词（或代词）做进一步解释的。
它可以是单词、短语或从句。
同位语从句是名词从句的一种，置于某些名词之后。
这些名词包括：fact, doubt, idea, news, hope, indication, decision, possibility, assumption, suggestion, question 等。
这类从句通常由that引导，有时也可用what, why, whether, when等引导。
在阅读和翻译的时候，要特别注意的是同位语和它的本位语分割的情况。
这种情况通常是为了保持句子的平衡而出现的。
在翻译的时候，这种分割成分的译法比较灵活，可将其提前，也可不提前，还可以增加“即”，或是用冒号、破折号等分开。
1. At the same time, the American Law Institute——a group of judges, lawyers, and academics whose recommendations carry substantial weight——issued new guidelines for tort law stating that companies need not warn customers of obvious dangers or bombard them with a lengthy list of possible ones.分析：the American Law Institute后面跟了一个同位语a group of judges, lawyers, and academics whose recommendations carry substantial weight，用破折号隔开了。

四、语法解读名词性从句之二同位语从句在复合句中充当同位语的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，它是中学英语学习的重点语法项目，也是历年高考英语试题中的重要考点。
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示的具体内容。
如:The news that our women volleyball team had won the championship encouraged us all greatly。
I’ve come from Mr Wang with a message that he won't be able to see you off this afternoon。
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。
如：The thought came to her that maybe she had left the door open when she left home。
The story goes that he failed in the college entrance examinations again.（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，并且往往有限定词加以修饰（word除外）。
如：Where did you get the idea that I could not come？Give me your promise that you will come to our party this evening.Word came that China launched its second manned spaceship on Oct.12,（2005.（三）同位语从句连接词的选用引导同位语从句的词通常有连词代词that，who;连词whether；连接副词how,when where等。

【真题剖析】
(江西名校信息卷)The moment ________ Leo will neverforget is ________ Mr.Green gave him a lot of valuable advice on how to improve his writing.
(3)当when, why, where和how引导同位语从句时，它们为连接副词。虽然它们在从句中充当句子成分，但前面没有与其意义相当的先行词。引导定语从句的when, where, why是关系副词，在它们前面分别有表示时间、地点、原因意义的名词作先行词。
He can answer the question how oxygen is joined with other elements.

人教课标版高中英语选修8Unit2GrammarPPT课堂课件(25页)
The news that l have passed the exam is true． (同位语从句，即从句所表达的意思就是前面名 词的内容)
The news that he told me just now is true. (定语从句，从句对前面名词起修饰限制作用， 即“他告诉我的”那个消息，而不是别的消息)
有时可用 namely (即), that is to say (也就是说), in other words (换句话说), that is (那就是), for example 等引出同位语, 说明其前面的名词或代 词。有时同位语直接跟在名词或代词的后面。
1. He told us the good news, namely, the museum is open to all.
3)、whether, what, how可以用来引导同位语 从句；而它们不能用来引导定语从句。
4)、从词义角度看 who, whom, which, when, where, why用来引 导同位语从句是保持原来疑问词的含义；它 们用来引导定语从句时，不具有疑问词的含 义。 从搭配角度看 who, whom, which, when, where, why用来引 导定语从句时对应性很强，如： 先行词是 “人”，引导词用“who”等，而它们引导同 位语从句是先行词通常是 “question, idea, doubt等”。

(人教版)高中英语选修八(教学资料,补习资料)：Unit 2 Cloning复习同位语及语法讲解
复习同位语概念引入同位语，也许这个名词不像定语、状语、主语等那么眼熟，但是在英语语法中也是不可缺少的内容，尤其是同位语从句，更是名词性从句的重点和难点。
在这个单元里，我们就来小结一下同位语，尤其是同位语从句的一些重要的用法。
先看下面句子：1. The whole scientific world followed the progress of the first successful clone, Dolly thesheep.2. Then came the disturbing news that Dolly had become seriously ill.3. Altogether Dolly lived six and a half years, half the length of the life of the originalsheep.4. The fact that she seemed to develop normally was very encouraging.这些句子中斜体词部分都是同位语，其中句2和句4是同位语从句。
那么同位语到底是什么样的句子成分？什么样的词语或从句能作同位语？应该注意什么呢？下面我们将就这些问题进行讨论。
用法讲解同位语的定义与构成同位语（Appositive）定义对句子中某一成分作进一步解释、说明，与前面名词在语法上处于同等地位的句子成分叫同位语。
同位语常放在被说明的词之后, 说明它们的内容、性质和情况等，有时有逗号隔开。
例如：Mr. Wang, my chi ld’s t eacher, will be visiting us on Tuesday.王先生，我孩子的老师，星期二要来看我们。
（Mr. Wang是句子的主语，而my child’s teacher说明主语的身份，是同位语。
）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？”（句尾的直接引语说明the question的内容，是同位语）同位语的构成1. 名词(短语)或all, each, both等代词及短语(有时有逗号隔开)We students all respect Mr. Johnson, our English teacher.我们学生都很尊敬我们的英语老师，约翰逊先生。

⑷ 同位语从句与定语从句的区别:
同位语从句与定语从句在使用中常常混淆, 我们可以从以下几个方面区别它们: ① 同位语从句说明的名词大都是抽象名词; 定语从句所修饰、限定的名词或代词有抽象
的也有不抽象的。

③ 由when引导

China again. (同位语从句)
Those who want to go please sign their names here. (定语从句)
② 同位语从句所说明的名词与从句没有 逻辑关系；

four-day visit in china.
3. Teenagers shouldn’t spend too much
time online. / Many Chinese parents
hold the view. Many Chinese parents hold the view
that teenagers shouldn’t spend too
⑤ 从引导词来看: 引导词that在同位语从句中 是连词, 只起连接作用, 无具体词义, that 不可省略; that在定语从句中是关系代词， 它在从句中充当一定成分—主语或宾语， 有具体词义, 作宾语时还可以省略。例如： a) The factory ______ (that) we visited yesterday 定语从句 is a chemical one. that he will leave for b) The news ______ Shanghai is true. 同位语从句
注意:
同位语从句有时被别的词把它 和名词隔开：
The story goes that William Tell killed the king with an arrow. Word came that their team had won.
