 ♣ 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。
