同位语从句用于对前面的名词作进一步解释，说明名词的具体内容。同位语从句一般由that引导，但也可以由whether 以及连接代词和连接副词引导。
同位语从句一般跟在名词fact, hope, idea, news, doubt, suggestion, information, opinion, decision, discovery, truth, promise, statement, problem, rule等的面。
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？
I have no idea whether he'll come or not. 我不知道他是否来。
在一些表示建议、命令、要求的名词后的同位语从句中，谓语动词用should+动词原形表示，should可省略。
This is our only request that this (hould) be settled as soon as possible. 尽快解决这个问题，这是我们唯一的请求。
He made the suggestion that we go by train. 他建议我们坐火车去。
