爱华网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 overthe 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 couldnot come?你在哪儿听说我不能来？
Early in the day came the news thatGermany 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 ornot.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 workrequires consideration.谁该干这项工作，这个问题需要考虑。
We haven’t yet settled the questionwhere we are going to spend our summervacation.到哪儿去度暑假，这个问题我们还没有决定。
It is a question how he didit.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?
句法功能 | 意义 | |
that引导的同位语从句 | 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。 | 补充、说明 |
that引导的定语从句 | 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。 | 修饰、限定 |
如：The news that Mr. Li will be our newEnglish 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 istrue. (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should+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。
