同位语从句

一 .同位语从句的概念：

同位语从句在句中做某一名词尤其是抽象名词的同位语，一般位于这名词之后，说明该名词的具体内容。这类名词常见的有 news, fact, idea, promise, suggestion, order 等。同位语从句一般用 that, whether 引导，也可用连接代词或连接副词引导。如：

E.g.: I made a promise that I would make him happy.

E.g.: I have no idea what he is doing now.

E.g.: She raised the question where we could get the fund.

二 .同位语从句的引导词：

1.that引导同位语从句：此时同位语从句有明确的、确定的含义，关系词that 仅起连接作用，不在从句中充当任何成分。如：

E.g.: Many parents hold the view that teenagers shouldn’t spend too much time online.

2.whether 引导同位语从句：whether所引导的同位语从句明显还有“选择”的意味，此时whether 多做“ 是否”解，whether 与 or 连用时，则表示“是„„，还是„„”。如：

E.g.: He hasn’t made the decision whether he will go there.

3.连接代词引导同位语从句：此类同位语从句含有“疑问”的意味，常用的连接代词有

what, who(m), whose, which, 等，what, whose, which 可在从句中作主语、宾语、表语或定语，who 在从句中多作主语，而whom 则充当宾语。如：

模块三 Unit 5 同位语从句同步语法讲解与操练

一、概念讲解

所谓同位语，是指跟在某些名词的后面，对前者做进一步的解释、说明、补充和概括，但不对前者起修饰作用的一种句子成分。

１、 定语从句相当于一个形容词, 它对先行词起修饰、描述和限制的作用。同位语从句相当于名词，属于名词性从句，它是对前面名词内容的具体表述，它们之间的关系是同位关系。

２、that 在定语从句中充当某一成分, 是关系代词; that 在同位语从句中不作任何成分，仅把主句与从句连接在一起，是从属连词。

３、when, where, why, how, who, whom, which 如果引导定语从句, 它们分别指前面先行词所表示的时间、地点、原因、方式、人和物，否则引导的就是同位语从句。

４、whether, what 可引导同位语从句，但通常不可引导定语从句。

５、同位语从句常跟在 news, fact, promise, idea, word, message, hope, truth, answer, proposal,

suggestion, order, information 等少数名词之后，而一般名词之后都可跟定语从句。

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？
