The problem is that we don

名词性从句 在复合句中具有名词的性质的作主语、表语、同位语、宾语的从句叫名词性从句。因此，

⑤同位语从句与定语从句中that的区别。
同位语从句中的连词 that只起连接作用，在从句中不担当任何句子成分；而定语从句中的关系代
词 that在句中做宾语或主语，宾语与先行词有修饰关系。如果句子是同位语从句，就应用连词that而
不能用 which同. 位语从句一般放在表具体含义的名词后解释名词的含义或内容，如以下名词：news、
②宾语从句中的连接词that有时可省有时又不可省，在以下几种情况中that不能省略：（A）当 that
从句和主句谓语动词之间有插入词语或者从句主语之间有插入语时，that不可省略；（B）当 that 从句
与另一名词性从句并列作宾语时，that不能省；（C）当 that作介词宾语时，that不可省掉。如： He judged that, because he was a child, he did not understand wine Everyone knew what happened and that she was worried. The reason lies in that she works harder than the others do. ③that从句作主语和宾语时，可以用it 来替换成以下几种结构表达。
同位语从句 用作同位语的从句叫同位语从句。它一般跟在抽象名词fact ，idea ，news，hope，belief ， thought ，truth ，doubt，suggestion ，warning, instruction ，reason，information, question 等
