when，where，why作為定語從句的引導詞，總稱為關係副詞。下面用句子合併的方法分析它們的使用。
一、where引導的定語從句
請分析下面兩個簡單句：
句①I know a garden.
句②You can find wild strawberries there.
把句②變為句①的定語從句，句①中的agarden做定語從句的先行詞。在句②中there指句①中提到的agarden也就是定語從句的先行詞，there在句中做地點狀語，因此要用where引導定語從句，代替句②中的there，也就是說there就不能出現在定語從句中了。由此得到句③I know a garden where you can find wild strawberries.
句②還可以寫作句④You can find wild strawberries in it(it指句①中的garden，“在花園中”要使用介詞短語in the garden)。把句④變為句①的定語從句，因為it做介詞in的賓語，先行詞是agarden，指物。在這種定語從句中介詞常常提到定語從句的開始，這時關係代詞只能使用which替代it，it就不能在定語從句中出現了。由此得到句⑤即：I know a garden in which you can find wild strawberries.
請把下面每組的兩句話合併為一句，把第二句話變為第一句的定語從句。
第一組：
This is the village.
I was born there.
→This is the village where I was born.
第二組：
The lab is not far from here.
The chemist often does experiments there.
→The lab where the chemist often does experiments is not far from here.
二、when引導的定語從句
請分析下面兩個簡單句：
句①We shall remember the days.
句②We studied together then.
把句②變為句①的定語從句，句①中的the days做定語從句的先行詞。在句②中then指句①中提到的the days，也就是定語從句的先行詞，then在句中做時間狀語，因此要用when引導定語從句，代替句②中的`then，也就是說then就不能出現在定語從句中了。由此得到句③We shall remember the days when we studied together.
句②還可以寫作句④We studied together during the days.(介詞短語during the days含義為“在這些日子裡”)。把句④變為句①的定語從句，因為the days做介詞during的賓語，先行詞是the days，指物，在定語從句中介詞during提前，用關係代詞which替代the days，the days就不能在定語從句中出現了。由此得到句⑤We shall remember the days during which we studies together.
請把下面每組的兩句話合併為一句，把第二句話變為第一句的定語從句。
第一組：
I''ve always longed for the days.
I should be able to be independent then.
→I''ve always longed for the days when I should be able to be independent.
第二組：
There are moments.
I forget all about it then.
→There are moments when I forget all about it.
三、why引導的定語從句
請分析下面兩個簡單句：
句①He wanted to know the reason.
句②I was late for the reason.
把句②變為句①的定語從句，句①中的the reasons做定語從句的先行詞。因為the reason做介詞for的賓語，先行詞是the reason指物，在定語從句中介詞for提前，用關係代詞which替代the reason，the reason就不能在定語從句中出現了。由此得到句③He wanted to know the reason for which I was late.
注意：在定語從句中當先行詞為the reason(s)，定語從句由for which引導時，可以用why代替for which。由此我們得到句⑤He wanted to know the reason why I was late.
請把下面兩句話合併為一句，把第二句話變為第一句的定語從句。
The reason is not very convincing.
He came for the reason.
→The reason why he came is not very convincing.
The reason for which he came is not very convincing.
