Fast、quick 還是 quickly 呢?

Fast 和 quick 均意為「快的;迅速的」。Fast 可用作形容詞和副詞,而 quick 僅當形容詞用,其副詞為 quickly (立刻,馬上;迅速地)。雖然 quick 有時亦被用作副詞,但這並非標準英語。例如:

  • The police car was going so fast; it must have been chasing someone. (警車開得很快,一定是在追人) - fast 當形容詞用。
  • Allen walks very fast. (艾倫走路很快) (正) - fast 當副詞用。
    Allen walks very fastly. (誤) - 英文沒有 fastly 這個字。
  • He’s a quick learner/study. (他學東西很快) - quick 當形容詞用。
  • Mary replied very quickly. (瑪麗馬上就回覆了) - quickly 是 quick 的正規副詞。

Fast 是指速度非常快或高速的快,如火車行駛的速度、人類跑步的速度或動物奔跑的速度等等。例如:

  • John’s a remarkably fast runner/swimmer. (約翰是個速度非常快的跑者/游泳者) (正)
    John’s a remarkably quick runner/swimmer. (誤)
  • I love fast cars. (我喜歡速度快的汽車) (正)
    I love quick cars. (誤)


Quick 是指時間短或比預期時間來得短的快。例如:

  • The manager had a quick coffee and left the office. (經理匆忙喝完咖啡就離開了辦公室) (正)
    The manager had a fast coffee and left the office. (誤)
  • Five explosions were heard in quick succession. (短時間內接連聽到五次爆炸聲) (正)
    Five explosions were heard in fast succession. (誤)
  • Could you give me a quick answer? (你能立即給我答案嗎?) (正)
    Could you give me a fast answer? (誤)
  • I have only time for a quick word. (我只有可以簡短跟你說幾句話的時間) (正)
    I have only time for a fast word. (誤)

有時 fast 和 quick 可修飾同一個名詞,意思相同,即兩者為同義詞;但有時兩者意思不同。例如:

  • These companies just want to make a fast buck.
    = These companies just want to make a quick buck. (這些公司只想快撈一筆)
  • It’s quite a fast journey. (這是一次很快就結束的旅程)
  • It’s quite a quick journey. (這次旅程很短)
  • He’s a fast worker. (他是個能快速與異性交往的人)
  • He’s a quick worker. (他是個做事很快的人)

必須注意的是,漢堡等速食雖以烹飪或準備時間短且可立即供應為主要特色,但其英文是 fast food,不是 quick food。例如:

  • Her husband started a fast food chain. (她先生創辦了一家速食連鎖店)

  1. 本篇第一個例句: The police car was going so fast; it must have been chasing someone. (警車開得很快,一定是在追人) - fast 當形容詞用。

    我認為fast在此應是副詞
