▲ 定语从句与同位语从句的区别 ● The news that she is going to marry an American is surprising. 她要嫁给一个美国人的消息令人吃惊。 注：句中的that是连词，在从句中没有语法成分。该句与news并列，是同位语从句。 ● The news that he told me is not true. 定语从句 他告诉我的那个消息不是真的。 注：句中that是关系代词，在从句中做told的宾语，引导的是定语从句。

定语从句与同位语从句的区别在于从句部分是否完整。完整就是同位语从句，不完整就是定语从句。 ● The news that she is going to marry an American is surprising. 从句部分she is going to marry an American is surprising. 主谓宾齐全，同位语从句。 ● The news that he told me is not true.从句部分he told me 其中told缺少宾语tell sb. sth. 故是定语从句。
