for 跟 because 都有「因為」的意思,但有什麼不一樣?(在同是當連接詞的情況下)

繼之前提供了 for 的13個當介系詞的字典定義(在[學英文囉!]的分類),今天則繼續說明 for 當連接詞進階用法。

雖然 'for''because' 都可以表示「因為」,但在語法、用法和語氣上有明顯的差異。


ComparisonForBecause
語法結構連接詞 (Conjunction),但較正式,常用於書面語。位置通常在句中。
e.g., He stopped running, for he was out of breath.
連接詞 (Conjunction),較口語化,常用於日常對話。位置靈活,可放句中或句首。
e.g., Because it was raining, we stayed home. / We stayed home because it was raining.
語氣帶有邏輯性書面文語感,用來表達原因或進一步說明。直接、清楚表達原因,語氣較自然口語。
語序主要子句在前,原因子句在後。可以主句在前、原因子句在後,或相反。
使用場合書面語,常見於正式寫作、文學作品中。口語與寫作皆可使用,應用更廣泛。

詳解用法與例句

  1. For 用法:

    • 功能: 用來補充或解釋前面的句子。
    • 語氣: 較書面且有點古典文學的味道。
    • 語法規則: 不能單獨出現,for 子句不會置於句首

    例句:

    • She smiled, for she knew the answer.
      (她微笑了,因為她知道答案。)
    • He couldn’t attend the party, for he was feeling unwell.
      (他無法參加派對,因為他感到不舒服。)

    ⚠ 注意:

    • "for" 句子前面必須有主要子句,不能單獨使用
      For I was tired. → 不正確。
      I went to bed early, for I was tired.

  1. Because 用法:

    • 功能: 清楚表達原因。
    • 語氣: 自然、直接,適合口語或寫作。
    • 語法規則: "Because" 子句可放在句首或句尾。

    例句:

    • I stayed home because I was sick.
      (我待在家裡,因為我生病了。)
    • Because it was late, they decided to leave.
      因為時間很晚,他們決定離開。)

    ⚠ 注意:

    • "Because" 可單獨回答問題,用來表達原因。
      例子:
      • Why are you late?
        Because the bus was delayed.

比較 'for' 與 'because' 的例句

句子中文翻譯語氣差異

學生常見錯誤與正確示範

  1. 錯誤:

    • For 用於句首:
      For I was busy, I didn’t come.
    • 改正:
      I didn’t come, for I was busy.
  2. 錯誤:

    • 過度依賴 because,不理解 for 的用法:
      He didn’t eat because he wasn’t hungry, for he didn’t like the food.
      • 改正:
        重新組織句子,僅選擇一個連接詞。

記憶技巧:

  1. Because = Cause → 因為原因發生的事情。
  2. For = Formal → 正式語氣,書面語較常見。
