先行词用英语

先行词是在定语从句中,被定语从句所修饰的名词。

1、例如:He is a teacher who teach our English.

在这里定词从句who teach our English是来修饰前面的名词teacher，所以teacher就是一个先行词。

2、例句：He is Mr. Robertson who comes from England.

他是来自英国的罗伯森先生。

其中的“Mr. Robertson”是先行词，“who”是引导词。

先行词是定语从句的引导词前面的被定语从句所修饰的名词、代词，在定语从句中充当一定的成分，我们可以这样认为，之所以称它为先行词，是因为修饰它的定语从句总是放在它之后，先行词总是出现在定语从句之前，而不同于普通形容词修饰名词时，形容词位于名词之前。
