用法說明

How is "Efficient" different from similar structures?What usage mistakes are common with "Efficient"?

efficient in doing vs efficient to do

  • efficient in doing 強調在「進行某個特定活動或過程」時表現出效率。介系詞 in 後面通常接名詞或動名詞 (V-ing),指出效率發揮的領域。
  • efficient to do 強調「做某件事」這個動作本身是有效率的,常用於評價一個方法、系統或工具。結構常為 It is efficient to + VSomething is efficient to use/operate
  • 當主詞是「人」或「團隊」時,通常使用 efficient in (doing)。當主詞是「事物」或「方法」,且評論其使用效率時,兩者皆可能使用,但 efficient to use/do 更為常見。 EN: The new software is efficient in processing large datasets. 翻譯: 這款新軟體在處理大型資料集方面很有效率。

常見錯誤

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

×The company needs more efficiency workers.

The company needs more efficient workers.

混淆形容詞與名詞。'Efficient' 是形容詞,用來修飾名詞(如 workers)。'Efficiency' 是名詞,不能直接修飾另一個名詞。

×This medicine is very efficient for headaches.

This medicine is very effective for headaches.

混淆 'efficient' 與 'effective'。'Efficient' 強調以最少浪費(時間、資源)完成任務,而 'effective' 強調產生預期結果或效果。藥物是產生效果(effective),而非運作效率高(efficient)。

×She is efficient to handle multiple projects.

She is efficient at handling multiple projects.

使用錯誤的介系詞或結構。形容詞 'efficient' 後常接 'at + V-ing' 或 'in + noun' 來表示在某方面有效率,而非不定詞 'to + V'。

×This process is very much efficient.

This process is very efficient.

錯誤地使用 'very much' 修飾形容詞。'Very' 可直接修飾形容詞(如 very efficient)。'Very much' 主要用於修飾動詞(如 I like it very much)或用於比較級前(如 very much more efficient),通常不用於修飾原級形容詞。

×He is efficient that the work is done quickly.

He is efficient, so the work is done quickly.

錯誤的句子結構。'Efficient' 是描述人或事物的特質,不能引導一個 'that' 子句來說明結果。應使用並列句(用 so)或改寫句子來表達因果關係。

×This method is more efficienter than the old one.

This method is more efficient than the old one.

錯誤的比較級形式。'Efficient' 是多音節形容詞,其比較級為 'more efficient',而非加上 '-er' 字尾。
