ex : Before that, he lived in a small village _________ he was born.

(A) where 　(B) when　(C) at which　(D) what

李捷這麼說：關係副詞是一個多年來大考幾乎年年都考的概念！介係詞加上關係代名詞若是表示時間、地方、方法與原因時，就可以代換成關係副詞when、where、how、why。本題原本要填的東西應該是 in which，此時就可以代換成指地方的關係副詞 where。所以，本題的答案當然就是(A) where。

※文法焦點：「關係副詞」where, when, how, why

(1) where 為表「地方」的關係副詞, 可代換成 in ( on , at ) which。

ex : Before that, he lived in a small village in which he was born.　= Before that, he lived in a small village where he was born.

ex : Mary walks into the living room where John is watching TV.

(2) when 為表「時間」的關係副詞, 可代換成 in ( on , at ) which。

ex : I still remember the day on which he arrived.　= I still remember the day when he arrived.　= I still remember when he arrived.

ex : I remember the time when we went shopping by bicycle.

ex : Ice cream came from the East at the time when Marco Polo saw people eating it there.

(3) how 為表「方法」的關係副詞, 可代換成 in which, 通常 how 不與先行詞the way一起使用，但可用 that 。

ex : He tried to find out the way in which his best friend, John, learned English well.　= He tried to find out the way that his best friend, John, learned English well. = He tried to find out how his best friend, John, learned English well.

(4) why 為表「原因」的關係副詞，可代換成 for which 。

ex : Would you please tell me the reason for which you didn’t attend my wedding?　= Would you please tell me the reason why you didn’t attend my wedding?　= Would you please tell me why you didn’t attend my wedding?
