本文是由自考365网校整理的成人学士学位英语考试语法大全：同位语从句，供广大考生参考学习。

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that。

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。

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。

难点释疑：

1.that引导的同位语从句与定语从句之区别

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. 他昨天告诉我的消息是真的。（定语从句，that在从句中作told的宾语，可省。）

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。
