3.连接代词what ,which, who ,whom, whose
连接副词where ,how,when, why引导同位语从句的 that 在从句中不充当任何成分，无任何具体意思，一般不省略。
that 引导同位语从句e.g.
(1) The news that our team won the first prize excited all of us.
我们队得了第一名，这消息使我们都很兴奋。1. I have no idea how he did it.2. You have no idea how worried I was.
3. He often asked me the question whether the work was worth doing.
状语除 that外， 其余连词在从句中都具有各自的意义或成分。注意啦！！!状语是否同位语从句与定语从句区别:同位语从句与that引导的定语从句（1）从先行词看
同位语从句与名词之间在逻辑上是“主语+be+表语”的关系。该名词是需要做特殊解释说明的抽象名词。例如：
They were delighted at the news that their team had won.
The news was that their team had won.(2)从引导词来看
引导词that在同位语从句中是连词，只起连接作用，无具体词，that不可省略；that在定语从句中是关系代词，它在从句中充当一定成分——主语或宾语，有具体词意，作宾语时还可以省略。The factory (that) we visited yesterday is a chemical one.
The news that he will leave for Shanghai is true.They expressed the hope that they would come to visit China again.
The hope ( that ) she expressed is that they would come to visit China again.Let’s have a try at once同位语从句：they would come to visit China 对hope 进行具体的说明。定语从句： hope 充当express的宾语。 引导词that引导定语从句时, 在从句中一般作主语或宾语 (指物时还可以用which代替), 并且作宾语时常常省略；
that在同位语从句中仅起连接作用, 不充当任何成分, 并且不能省略, 也不能用which来代替，如: 一起小结that：II. 判断下列哪些含有同位语从句，哪些含有定语从句。
