同位语从句讲解与练习
1．定义：用作同位语的从句叫做同位语从
句。
2.用法：同位语从句的先行词多为fact,
news, idea, thought, question, reply,
report, remark等，关联词多用从属连词。
如：
They were all very much worried over
the fact that you were sick.对你生病这
件事，他们都很焦虑。
Where did you get the idea that I could
not come?你在哪儿听说我不能来？
Early in the day came the news that
Germany had declared war on Russia.
德国已对俄国宣战的消息一大早就传来
了。
注：同位语从句偶尔由从属连词whether
引导。如：I have no idea whether he’
ll come or not.我不知道他是否来。
连接代词who, which, what和连接副词
where,when, why, how亦可引导同位语
从句。
The question who should do the work
requires consideration.谁该干这项工
作，这个问题需要考虑。
We haven’t yet settled the question
where we are going to spend our
summer vacation.到哪儿去度暑假，这个
问题我们还没有决定。
It is a question how he did it.那是一个
他如何做了此事的问题。
1．that引导的同位语从句与定语从句之区
别?
that引导的同位语从句
that引导的定语从句
句法功能上
that只起连接从句的作用，无意义。
在从句中不充当句子成分。
不可省。
that替代先行词在从句中不仅起连接作
用，
还充当一个句子成分。如在从句中作
动词的宾语时可省略。
意义上
从句是被修饰名词的内容。
从句起限定作用，是定语
如：
The news that Mr. Li will be our new
English teacher is true. (同位语从句，
that不可省) 李先生将是我们的新英语老
师这个消息是真的。
The news (that) he told me yesterday
is true. (定语从句，that在从句中作的宾
语，可省)他昨天告诉我的消息是真的。
2．一些表示“建议、命令、要求”的名词
后所跟的同位语从句中，谓语动词用虚拟
语气sho uld+动词原形表示。should可
省。如：
This is our only request that this
(should) be settled as soon as
possible.这就是我们唯一的请求：尽快解
决这个问题。
