…, which …
非限定關係子句（逗號＋which／who）
Non-defining relative clauses — English grammar, senior high
接續
名詞, who／which ＋ 補充說明, …（前後加逗號，不能用 that）・, which 也可以指整句話
noun, who / which + extra information, … (commas; no that) · , which can refer to a whole clause
說明
加逗號的關係子句只是補充說明，拿掉也不影響句意：My sister, who lives in Taipei, is a nurse.（我姊姊住在台北，她是護理師。）, which 也能指前面整句：He passed the exam, which surprised everyone.
With commas, the clause just adds information and could be dropped: My sister, who lives in Taipei, is a nurse. , which can refer to the whole idea: He passed the exam, which surprised everyone.
注意事項
- 非限定子句不能用 that，也不能省略關係代名詞。Non-defining clauses can't use that or drop the pronoun.
