speed, rate这两个词都可作“速率”解。其区别是： speed指固定的速度或可能达到的最高速度,而在指相对增长的速率时用rate。试比较: The newly-designed airplane has a speed of 500 miles an hour.新设计的飞机速度可达每小时500英 里。

v.动词
speed, dash, hasten, hurry, quicken, rush这组词都有“催促”“赶紧”的意思。其区别是： quicken指动作变化短暂、快,活动性较强,使其变为更活泼、有力或敏捷; dash指在一个很短的距离内快速前进,也指赶忙做某事; hasten指在急速当中,有计划有秩序地,但有时也指突如其来和匆匆完事; hurry指迅速地移动,含有几分兴奋的意思,但也带有几分仓促、混乱的意思; rush指赶快、非常迅速地行进,所暗示的形势要比hurry来得更紧急,有时还带有暴力的意味; speed是一个比rush意思更强的词,与quicken近义,不同处在于暗示移动的快速。例如: Exercise quickens the pulse.锻炼使脉搏加快。
He dashed up the stairs.他冲上了楼梯。
The storm's approach hastened our departure.暴风雨将要来临,我们只好赶快离开。
The late arrivals hurried to their seats.迟到的人匆匆走到自己的座位上去。quicken，accelerate，hasten，hurry，rush，speed这些动词均含“加快，使加快”之意。 quicken普通用词，指增加速度、速率。 accelerate着重指频率或速率运转加快。 hasten指由于事的紧迫性或突然性而加速。 hurry指赶紧或匆忙地做某事或催促别人做某事，隐含草率或混乱意味。 rush含义与hurry相近，但显得更仓促更慌乱。 speed侧重实际的快速行动,常用词组是speed up。 speed，rate，velocity，pace这些名词均含“速度、速率”之意。 speed普通用词，指单位时间内行进的固定速度或速率，也指可能达到的最高速度。 rate作“速度”讲时，与speed同义，可换用。作速率解时，指相对增长的速度，也指两种相比较而得出的标准速度。 velocity技术用词，指物体沿着一定方向运动时的速率。 pace普通用词，指步行的速度，常引申指活动的进度或生产率。 直接源自古英语的sped，意为成功。
