關(guān)系副詞和介詞加關(guān)系代詞之所以能轉(zhuǎn)換,是因?yàn)樗鼈兊男再|(zhì)決定的.副詞在句中可以做狀語,介詞短語也可以作狀語.都在句中作狀語這一特點(diǎn)是他們能轉(zhuǎn)換的基礎(chǔ).
比如：He was born in that town.和 He was born there.兩個(gè)句子都是說他出生的地方.其中
in that town = there .換成關(guān)系詞就是 in which =where (其中的which 在原文中就是the town.
翻譯：這就是他出生的那個(gè)城鎮(zhèn).
This is the townand he was born in the town.= This is the town in which he was born.(which=the town)
還可以這樣翻譯：This is the town and he was born there(there =in the town).=
This is the town where he was born(where 就是原句中的there).
why 和when 的轉(zhuǎn)換和where的用法類似.只是why用來修飾reason,when 用來修飾時(shí)間名詞.
