Step 2 Discovering useful structures 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, 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.

⑵

同位语从句的表现形式: ①

由that引导

The fact that you haven’t enough time to do the work is simply unbelievable.

The hope that he may come here is not gone yet. ②

由whether引导

The question whether we need more time to do the work has not been discussed. ③

由when引导

I have no idea when they will go. 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) 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。

He heard the news that their team had won.

此句可以变为一个表语从句:

The news was that their team had won.

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 ______ we visited yesterday is a chemical one.

b) The news ______ he will leave for Shanghai is true. Step3 Exercise 1 on Page 14: Exercise 2 on Page 14:
