◇ Relative Pronouns vs. Relative Adverbs
關係代名詞 vs. 關係副詞
常見的關係代名詞和關係副詞多以 wh- 開頭，如 who、whose、which等，而關係副詞有 where、when。關係代名詞可代替先行詞 (關代前的名詞)，例如 And unlike Xi Jinping, whose term is unlimited, Trump faces voters next year 這句就是用 whose 來描述 Xi Jinping。 Whose 是 who 的所有格，代表「習近平的…」。另外，當一個動詞片語包含介系詞時，可把介系詞「移到關代之前」，或直接省略介係詞而使用關係副詞。舉例來說，... not one in which the U.S. is involved 可以改成 not one where the U.S. is involved。這種副詞取代介系詞＋名詞的概念，其實我們已經很熟悉了，例如 I lived in the city， in the city 就可以被 there 取代。
Example：
1. That college where I studied ten years ago is beautiful.
那間我十年前念書的大學很漂亮。
2. It's one of the few countries where people drive on the right.
那是少數其中一個右駕的國家。
3. Not only is he in a position where he has to make tough decisions, but he also doesn't cop out of them.
他不僅處於必須做出艱難決定的位置，而且他也沒有逃避這些決定。
