2. fast可以表示钟表时间的快,但要放在时间名词之后,而不能按汉语的表达习惯放在前面。

adv.(副词)

2. fast可与介词连用,如by, in等。

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。

Come quickly, he's drowning!快来,他溺水了。

adj.(形容词)

误 The train was going more and more fast.
