定语从句做题步骤
1.判断用关系代词还是关系副词，如缺少主语/宾语/表语/定语，用关系代词；如缺少状语，用关系副词。
2.如用关系代词，则遵循以下三点：
找出先行词
看先行词指人还是指物
看关系词在从句中所作成分
关系代词 先行词指人/物 关系词在从句中所作成分

which 物/整个句子 主/宾/表
who 人 主/宾/表
whom 人 宾/表
whose(……的） 人/物 定
先看先行词，辨清人和物；
再看从句里，有无主宾语；
若无主宾语，就用关系代；若有主宾语，就用关系副。
3. 如用关系副词，则遵循下表：
关系副词 先行词 关系词在从句中所作成分
When=介词(in/on/at/during)+which 时间名词 时间状语
Where=介词(in/at/on)+which 地点名词 地点状语

where的先行词：position/point/case/stage（阶段）/situation

二动：根据从句谓语动词的搭配来确定；
The man to whom you spoke is a teacher.
三意义：根据从句表达意义来确定。
