2.同位语从句the Appositive clause
(1)同位语从句的定义
在复合句中用作同位语的从句称为同位语从句。同位语从句是名词性从句的一种。它在句中起同位语的作用。
它一般放在fact, news, idea, truth, hope, problem, information, belief, thought, doubt, promise, question 等名词的后面, 对前面的名词作进一步的解释, 说明前面名词的具体含义。引导同位语从句的词有连词that, 连接副词how, when, where, whether, what等。
e.g.
The hope that he may recover is not gone yet.
The problem whether we should continue to do the experiment has been solved.
I have no idea when he will come back.
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.
(2) 同位语从句的表现形式:
①由that引导

The hope that he may come here is not gone yet.
The news that he has been elected president of the United States is true.
The truth that heavy objects and light objects fall at the same speed is known to all.

②由whether引导

③由when引导

(3)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。
He told us the good news, namely, the museum is open to all.
There is only one way of improving your English, that is, to practice more.

(3) 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。
We express the hope that they will come to visit 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;
定语从句所限定的名词是从句逻辑上的主语、宾语、表语、定语、状语等。
The news that they won the match is true. (同位语从句, news和从句没有逻辑关系)
The news that you told us yesterday is true. (定语从句, news是told的逻辑宾语)
The order when we should go back hasn’t reached us.
(同位语从句, order和从句没有逻辑关系)
The day when New China was founded will never be forgotten.
(定语从句, day是founded 的逻辑状语)
③同位语从句主要由连接词that引导,有时也可用when, where, who, whether等引导;
定语从句由关系代词或关系副词引导。
Then he raised the question where they were to get the machine needed.
Do you know the place where he was born?
④引导同位语从句的连词不可省略;
引导定语从句的关系代词作宾语时常可省略。
The news that he has been elected monitor of our class is true.
The news (that) he told me is exciting.
⑤同位语从句与先行词一般可变成一个完整句子, 谓语动词用be的不同形式。

此句可以变为一个表语从句: The news was that their team had won.
