同位语从句属于名词性从句,大多由从属连词that引导,常常跟在fact, idea, opinion, news, hope, belief等名词后面。
同位语从句一般用来解释或说明这些名词的具体含义或内容,在逻辑上表现为同位关系。
例如: They are familiar with the opinion that all matter consists of atoms.他们很熟悉这一观点,所有的物质都是由原子构成的。
从先行词来看 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说明的抽象名词。
例如: They were delighted at the news that their team had won.当听到他们的球队赢了的消息时,他们欣喜若狂。
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,无具体词义,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。
试比较: The factory(that)we visited yesterday is a chemical one.我们昨天参观的那家工厂是化工厂。
(that在从句中作宾语,所以此句是宾语从句) The news that he will leave for Shanghai is true.他将要去上海的消息是真的。
(that只起连接从句的作用,所以此句是同谓语从句)。
