注意：不是表時間的先行詞都用when引導定從，不是表地點的先行詞都用where引導定從。例如：Well visit the factory which(=that) makes radios.

(which或that在定從中作主語，where不可用主語，故不可用)

(which或that在定從中作spent的賓語，when不可作賓語，故不可用)

定語從句引導詞及用法

引導定語從句的關聯詞稱為關係詞，關係詞有關係代詞和關係副詞。關係代詞有that， which， who， whom， whose， as等關係副詞有where， when， why等。關係詞常有3個作用：

1、引導定語從句。

2、代替先行詞。

3、在定語從句中擔當一個成分。

關係副詞引導的定語從句

1. when指時間，在定語從句中做時間狀語

(1) I still remember the day when I first came to the school.

(2) The time when we got together finally came.

2. where指地點，在定語從句中做地點狀語

(1) Shanghai is the city where I was born.

3. why指原因，在定語從句中做原因狀語

(1) Please tell me the reason why you missed the plane.

(2) I don’t know the reason why he looks unhappy today.

注意：關係副詞引導的從句可以由“介詞+關係代詞”引導的從句替換

(1) The reason why/ for which he refused the invitation is not clear

(2) From the year when/in which he was going to school he began to know what he wanted when he grew up.

(3) Great changes have taken place in the city in which./where I was born.
