that 與 which 在引導關係子句時的區別
- that 通常用於引導限定性子句，對先行詞的定義至關重要，若省略會改變句意。
- which 則常用於引導非限定性子句，提供額外、非必要的補充資訊，通常前後會用逗號隔開。
- 在限定性子句中，若先行詞是「人」，通常用 who/whom；若是「物」或「動物」，則 that 或 which 皆可，但口語中 that 更常見。
- 當先行詞包含「最高級」、「序數詞」（如 the first, the only）或「不定代名詞」（如 all, any, everything, nothing）時，通常傾向使用 that。
對比範例： EN: The book that you lent me is fascinating. 翻譯: 你借給我的那本書非常引人入勝。
EN:This novel, which won several awards, is a bestseller.
翻譯:這本小說，它得了好幾個獎，是本暢銷書。
EN:Everything that he said turned out to be true.
翻譯:他所說的一切後來都被證實是真的。
EN:The house, which was built in 1920, has a beautiful garden.
翻譯:這棟房子，建於1920年，有一個漂亮的花園。
總結建議
在限定性子句中描述「事物」時，使用 that 通常安全且自然；當子句僅為補充說明（前後有逗號）時，則使用 which。

停頓填充
在思考或組織句子時，"that" 有時會被用作口語中的填充詞，類似中文的「那個…」，本身可能沒有太多實質意義。 EN: The thing is… that… I’m not really sure how to start. 翻譯: 事情是…那個…我不太確定該怎麼開始。
EN:I was going to tell her that… um… that I might be late.
翻譯:我本來要告訴她…嗯…那個…我可能會遲到。

在正式或書面英語中，當 'that' 作為主詞或受詞時，通常不能省略。口語中雖然有時會省略，但學習者應先掌握完整形式。
×This is the man this helped me.
✓This is the man that helped me.
'that' 可用作關係代名詞，引導形容詞子句修飾前面的名詞（此處為 'the man'）。'this' 不能用作關係代名詞。
×The fact that he is late that worries me.
✓The fact that he is late worries me.
當名詞（如 'the fact'）後面已經用 'that' 引導了一個名詞子句作為補充說明時，不應再使用另一個 'that' 來連接主要動詞。一個子句通常只需要一個連接詞。
×I like that books.
✓I like those books.
作為指示限定詞（demonstrative determiner），'that' 修飾單數或不可數名詞（that book, that water）。修飾複數名詞時必須使用 'those'。
×She suggested we leave early.

在較正式的文體或書寫中，某些動詞（如 suggest, recommend, insist）後面的名詞子句，連接詞 'that' 通常不省略，以保持清晰。口語中省略較常見。
×It was so cold I couldn't feel my fingers.
✓It was so cold that I couldn't feel my fingers.
在 'so...that...'（如此...以致於...）的句型中，'that' 作為連接詞引導結果子句，在正式寫作中通常不省略，以避免歧義或結構鬆散。
