| Key takeaways |
| – Because +子句 → 直接解釋原因（在句首或句中） – Because of + 名詞/名詞片語 → 用於沒有動詞的情況（句首或句中）。 – Due to + 名詞/名詞片語 → 正式的（通常位於“be”之後，句中） – Owing to + 名詞/名詞片語 → 正式的（在句首或句中） – Since + 子句 → 輕率的、自然的理由（通常位於句首） – As + 子句→ 明確的理由（通常位於句首） – Thanks to + 名詞/名詞片語 → 強調積極影響（句首或句中） – On account of + 名詞/名詞片語 →正式的（在句首或句中） – For + 子句 → 正式寫作（限句子中間部分） – Seeing that + 子句 → 強調顯而易見的原因（放在句首或句中） |
因為 英文: Because / Because of
“因為“英文有兩種基本結構，學習者應該掌握：because 和 because of。這兩種形式很容易混淆，但只要正確理解它們的本質，就能在任何句子中正確使用。
because 用法 (Conjunction)
Because 是一個連接詞，用來給出理由，後面必須跟著一個子句 (S + V)。因為英文句首以強調原因，或者放在句中連接兩個意思。
結構:
| Because + S + V |
例子:
- Because I was tired, I went to bed early. (因為我累了，所以我早點睡了。)
- I stayed home because it was raining. (因為下雨，所以我待在家裡。)
“Because”, 因為英文縮寫: ’cause, cuz / cuz’, coz / cos, bc / b/c, bcuz / b’cuz
because of 用法 (Prepositions)
介詞“because of”也表示“因為”，但它後面必須跟名詞、名詞片語或代名詞，絕對不能跟著子句。這是因為英文開頭，也可以在句中。
結構:
| Because of + N / N-phrase / pronoun |
例子:
- The flight was delayed because of the weather. → (Noun)
(由於天氣原因，航班延誤了。)
- We canceled the picnic because of heavy rain. → (Noun phrase)
(由於下大雨，我們取消了野餐。）

因為 英文: Due to (Prepositions)
Due to 是英語中非常常見的介詞，意思是“因為/由於”，常用於正式寫作、報紙、公告、工作郵件或需要更精確表達的場合。 due to 用法通常出現在動詞 to be 之後，後面總是跟著名詞或名詞片語。
結構:
| Due to + N / N-phrase |
例子:
- The cancellation was due to bad weather. (取消是由於天氣不好。)
- His success is due to hard work and consistency. (他的成功由於勤奮和堅持。)
>>有趣知識：yet 用法：位置、意思、造句與簡單練習
因為 英文: Owing to
Owing to 常用於書面語、公告、報紙以及正式或專業場合。owing to 用法後接名詞/名詞片語，可以位於句首或句中。
結構:
| Owing to + 名詞/名詞片語 |
例子:
- Owing to the traffic jam, we arrived late. (由於交通堵塞，我們遲到了。)
- Several flights were canceled owing to the storm. (由於暴風雨，多班飛機被取消。)
>>常用結構：although 用法：詳細解釋、例句與應用練習
因為 英文: Since (Conjunction)
since 因為 用法, 用作連接詞，用來給出自然而溫和的理由，前提是聽者已經清楚原因。 “since” 後面必須跟著子句(S + V)。位置靈活：可以放在句首，也可以放在句中。
結構:
| Since + 子句 (S + V) |
例子:
- Since I’m not feeling well, I’ll stay home today. (因為我身體不舒服，今天就待在家裡。)
- We canceled the trip since the weather was terrible. (由於天氣惡劣，我們取消了行程。)
此外，since 一詞也有“自從“的意思，詳見本文：since 用法：意義、規範用法、區分方法及記憶技巧
