n.(名词)

1. speed作名词的基本意思是“速度,速率”,指运动事物在单位时间内所通过的距离。作此解时, speed本身无所谓快慢,若表示“快”或“慢”,须加形容词修饰。可用作可数名词,也可用作不可数名词,用作可数名词时,其前常加不定冠词a。
2. speed也可作“快,快速”解,指运动本身的速度、频率快,是不可数名词。
3. speed后常接of短语作定语,有时speed可用在名词前作定语。

v.(动词)

1. speed用作动词是“提速”“加速”的意思,含有“有成效”而不带有兴奋与慌乱的意味,也可指驾车者以违法的速度行驶。
2. speed可用作及物动词,也可用作不及物动词。用作及物动词时,接名词或代词作宾语。

n.(名词)

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。

照目前的发展速度,我们不久就能实 现四个现代化。

speed, velocity

speed指运动的速度,既可指快速,也可指慢速; velocity表示沿一定路线运动的速度,通常指直线、弧线或圆周运动的速度,这个词可与speed通用,但多用于科学技术方面。例如:

The velocity of sound falls far short of the speed of light.音速远不及光速快。

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。

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。

n.(名词)

误 Tom was driving his sports car at the unbelievable high speed.

误 The motorcar turned the corner at a full speed.

正 The motorcar turned the corner at full speed.
