選擇哪個關系詞關鍵要看：
1）一看是限定性定語從句還是非限定性定語從句：非限定性定語從句一般不用that引導。
2）二看先行詞是人還是物：which不能指代人，who, whom不能指代物，that和whose既可代替人也可代替物。
3）三看關系詞在定語從句中的作用：who, that, which可以作主語，也可以作賓語；whom只能作賓語； whose只能作定語；when, where, why在定語從句中作狀語。
4) 先行詞是地點，不一定用where，關鍵要看定語從句中缺少什么成分，缺少地點狀語用where，缺少主語、賓語用that/which。先行詞是表示時間的名詞不一定用when，在定語從句中作時間狀語才用when，如果在從句中作主語、賓語要用that/which。先行詞是reason, way時也一樣，關鍵要看在從句中作什么成分。
