什么是同位语从句

Answer 1

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.
