upon doing vs upon to do

  • upon doing 表示「一...就...」,強調緊接著某個動作之後立即發生的反應或結果。
  • upon to do 在標準英語中是錯誤的結構,因為 "upon" 是介系詞,後面應接名詞或動名詞 (V-ing),而非不定詞 (to V)。
  • 在正式或書面語中,"upon" 與 "on" 在此用法上常可互換,但 "upon" 聽起來更為正式。 EN: Upon hearing the news, she burst into tears. 翻譯: 一聽到這個消息,她立刻淚流滿面。

EN:He insisted upon seeing the manager.

翻譯:他堅持要見經理。

總結建議

在表達「一...就...」時,請使用 "upon + V-ing" 的結構,並避免使用不存在的 "upon to do"。

常見錯誤

What are common mistakes with "Upon"?Which "Upon" sentences look correct but are wrong?

×I put the book on the table.

I put the book upon the table.

在現代英語中,'on' 比 'upon' 更常用於描述物體的物理位置。'upon' 聽起來較為正式或文學化,在日常對話中,'on' 是更自然的選擇。

×Once upon a time, there was a princess on a hill.

Once upon a time, there was a princess upon a hill.

'Once upon a time' 是固定片語,不可將其中的 'upon' 替換為 'on'。但在片語之後的句子中,描述位置時仍可使用 'on'。此處 'upon a hill' 是為了風格一致,顯得較為詩意。

×He climbed up on the roof.

He climbed upon the roof.

'up on' 是副詞 'up' 加上介系詞 'on',強調向上移動後抵達某表面的動作。'upon' 是一個單一的介系詞,意思與 'on' 相同但更正式,此處使用 'upon' 能使句子更簡潔、文雅。

×Upon I arrived home, I called you.

Upon arriving home, I called you.

'Upon' 作為介系詞,後面必須接名詞或動名詞 (V-ing),不能接子句 (主詞+動詞)。正確的結構是 'Upon + N/V-ing',表示『一...就...』。

×Upon it rains, the streets get wet.

When it rains, the streets get wet.

'Upon' 用於表示緊接在某個特定動作或事件之後,通常與具體的、瞬間的動作連用。對於像『下雨』這樣的自然現象或狀態,使用 'when', 'if', 或 'whenever' 更為自然。

×Success depends upon hard work.

Success depends on hard work.

'Depend upon' 和 'depend on' 意思相同,可以互換。但在現代口語中,'depend on' 遠比 'depend upon' 更常見。使用 'upon' 會讓語氣聽起來更正式、更強調。此錯誤屬於輕微的風格選擇問題,而非語法錯誤。
