宝贝，如果说三千能表达一个仪式，如果我有三千个宠爱，那我给你三千宠爱！
首先，请大家来自测一下下面几个题目，文章末尾有答案，如果你都做对了，那么恭喜你，这个文章你可以直接跳过不用看了，如果有错误，还是请你认真学习一下本文，请看：
(1) This is the room _________I lived ten years ago.
A. that B. where C. who D. what
(2) This is the room _________I lived in ten years ago.
A. that B. where C. who D. what
(3) This is the room _________I bought ten years ago.
A. that B. where C. who D. what
(4) This is the room _________I visited ten years ago.
A. that B. where C. who D. what
(5) This is the room _________I was born ten years ago.
A. that B. where C. who D. what
现在转入主题，请再看下面这道题，名词place后面该用什么关系词来引导定语从句：
He likes living alone, and says that he wants to go and live in a place _________ nobody knows.
A. where B. that C. when D. what
有的朋友一看到 place 是表示“地点”的名词，于是就毫不犹豫地选了A，但是错了，最佳答案应是B。表示“地点”的名词后到底是用 where 还是用 that 或 which 来引导定语从句，原则上应注意以下两点：
一是看关系词的句法功能。由于 where 是关系副词，它在定语从句中用作状语，而that 和 which 是关系代词，它们在定语从句中用作主语或宾语。所以区别是关系副词还是关系代词的关键就是看定语从句是否缺主语或宾语，若缺主语或宾语则用关系代词，若不缺主语或宾语则用关系副词。
二要看句意。一般说来，句子是否缺宾语，主要是看定语从句中的动词是否为及物动词或带有介词等，但问题是有些动词既可用作及物动词，又可用作不及物动词，它是否需要带宾语则要视句意而定。比较：
This is the school where I studied five years ago. 这是我五年前读过书的学校。（句中 study 用作不及物动词，意为“学习”或“读书”）
This is the school that I studied five years ago. 这是我五年前研究过的那所学校。(句中 study 为及物动词，意为“研究”)
