Answer 2

1、quick 通常表示某一动作来得突然或时间持续很短,有时还含有匆忙之意(通常不指动作的频率).如：She ate a quick breakfast and rushed off to work.她匆匆吃了早餐就赶去上班.
注：催人快做(快走等),通常用 quick.如：Be quick!快点!
2、 rapid 比另外两词要稍正式些,通常指突然或急速(且连续不断)的动作.如：
a rapid burst of machine-gun fire 机枪声骤起
He asked questions in rapid succession.他连珠炮似地发问.
另外 rapid 还有一个特殊用法,即指一种有益的高速度(相比之下,quick 有时指无益的急速).如：
He made rapid progress in English.他在英语方面取得了很快的进步.
3fast指人或者物体的速度很快
he runs fast他跑的很快
