怎样区别定语从句和同位语从句 - 六级语法

在英语复合句中，有些定语从句和同位语从句从表面形式上看非常相似，使许多人难以分辨彼此。本文拟从先行词和引导词两个方面对二者进行区别。 一、先行词

1．定语从句的先行词是名词或代词；而同位语从句的先行词只能是名词，而且仅限于idea，plan， fact，theory，promise，hope，news，doubt，truth，information，suggestion，question， thought，belief，conclusion等少数名词。例如：

①The boy who is playing football is my classmate． ②Those who work hard will succeed．

③The fact that he had not said anything surprised everybody． ④The fact that you are talking about is important．

在①句中，划线部分是定语从句，其先行词是名词 boy，它不能用作同位语从句的先行词。 在②句中，划线部分也是定语从句，其先行词是代词tho
