高考同位语从句详解与习题

同位语

一个(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。

同位语从句用法

一、同位语从句在句中的位置

1. 在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。 (如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.

我从王先生那边得知一个消息，他说他今天下午不能来看你了。

I heard the news that our team had won．我听到了我们队获胜的消息。

注：在名词doubt“怀疑”后的同位语从句用whether连接；在no doubt“不怀疑”之后的同位语从句用that连接。

We have some doubt whether they can complete the task on time.

我们怀疑他们是否能准时完成任务。

There is no doubt that Zhang Wei will keep his promise. 我们相信张卫会守信的。

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，在上叫做分隔式同位语从句。

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 thought came to him that maybe the enemy had fled the city．他突然想起可能敌人已经逃出城了。
