adv. (副词)

2. fast可与介词连用,如by, in等。

词义辨析

adj. (形容词)

fast, hasty, quick, rapid, sudden, swift

• 这组词的共同意思是“快的,迅速的”。其区别是：
• 1.quick指运动动作发生或完成的迅速、敏捷,强调的是单一动作的突然性或短暂性,也指才智和反应的敏捷和灵敏; swift意为“快”或“突然发生”,所指的运动速度最高,同时强调运动的平稳潇洒和轻捷、不费力气等,有时带文学色彩,为较正式的用语; fast多指运动的物体,位置移动的迅速,强调物体运动的方式; rapid是正式用语,多指运动本身,强调运动的高速度,所指的速度有时有“对人有益”的含义,常常可与fast互换使用,但语气比fast强; hasty指“草率,匆忙”; sudden则指“突然”。
• 2.swift, fast和rapid一般都指运动的速度,通常动作都有持续性和连续性。hasty一般都不指运动的速度。例如:
• He gave me a quick response to my question.他对我的问题给出了迅速的回答。
• The swift fading of autumn into winter.秋色迅速退去,随而进入冬天。
• The fast train was exchanged for a local one.快车被换成了慢车。
• He made such rapid progress that his parents were very glad.他取得了如此快的进步,以至于他的父母都很高兴。
• She's too hasty—if she would only think before speaking she wouldn't have so much trouble.她太性急了,要是她讲话之前多考虑一下,就不会有那么多麻烦了。
• A sudden clap of thunder woke me.一阵突然的雷声把我惊醒了。

adv. (副词)

fast, quickly, soon

• 这三个词都可表示“很快”。其区别是：
• soon强调的是预期的时刻不久就会到来, fast和quickly强调的是动作进行的速度快。例如:
• Their population is growing fast.他们的人口增长得很快。
• Come quickly, he's drowning!快来,他溺水了。

常见错误

adj. (形容词)

1. 你动作很快,对吧?

   误 You're very quick, aren't you?

   正 You're very fast, aren't you?

   析 指人的动作快,要用fast。

2. 快点!

   误 Be fast!

   正 Be quick!

   析 催促人走路或做事快,要用quick。

adv. (副词)

1. 海伦打字又快又好。

   误 Helen types fastly and efficiently.

   正 Helen types fast and efficiently.

2. 牢牢地抓住绳子,我会把你拉上来的。

   误 Hold fastly to the rope, and I will pull you up.

   正 Hold fast to the rope, and I will pull you up.

   析 fast既可作形容词表示quick/firm的意思,又可作副词表示quickly/firmly的意思。它的形容词和副词形式是相同的,英语中没有fastly这个词。

3. 火车开得越来越快。

   误 The train was going more and more fast.

   正 The train was going faster and faster.

   析 fast是单音节副词,其比较级形式是faster,最高级形式是fastest。
