1.概念：用作同位语的从句叫做同位语从句。
2.使用方法：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，他们都非常焦虑。Wher
did you get the idea that I could not come? 你在什么地方听说我不可以来? 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。
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 or
not.我不了解他是不是来。连接代词who,which,what和连接副词wher,when,why,how亦可引导同位语从句。The question who
should do the work requires consideration.哪个该干这项工作，这个问题需要考虑。We haven't yet
settled the question wher we are going to spend our summer
vacation.到什么地方去度暑假，这个问题大家还没决定。It is a question how he did it.那是一个他怎么样做了此事的问题。
