同位语从句讲解
一 定义：用作同位语的从句叫做同位语从句。
二 用法：同位语从句的先行词多为fact, news, idea, thought, question, reply, report,等，
（一）用从属连词that, whether。
Eg:1 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。
2.Where did you get the idea that I could not come?你在哪儿听说我不能来？
注：同位语从句偶尔由从属连词whether引导。
Eg: I have no idea whether he’ll come or not.我不知道他是否来。
（二）连接代词who, which, what引导同位语从句。
1.The question who should do the work requires consideration.
2.I have no idea what we can do with these waste materials。
3.I have no idea which class he is in.
（三）连接副词where, when, why, how亦可引导同位语从句
1.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。
2.It is a question how he did it.那是一个他如何做了此事的问题。
3.-- I drove to Zhuhai for the air show last week. -- Is that why you had a few days off
4. I have no idea when he will be back.
（四）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,起补充、说明作用。
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起修饰、限定作用
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。
注意：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。
