n.(名词)

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。

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。

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)

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。

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。

At the present rate of progress, we can shortly realize the four modernizations.

照目前的发展速度,我们不久就能实 现四个现代化。

v.(动词)

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。

n.(名词)两个赛跑者以同样速度前进。

误

汤姆正在以难以令人相信的高速驾驶着自己的赛车。

误

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

正

Tom was driving his sports car at an unbelievable high speed.

析

speed往往用于at a low speed或at a high speed的形式,表示“低速”或“高速”,这里的不定冠词a不能改为定冠词the。
摩托车高速拐弯。

误

The motorcar turned the corner at a full speed.

正

析

at full〔top〕 speed作“以全速”解时, full和top前没有冠词。
v.(动词)司机因超速而被罚款。

误

The driver was fined for over-speeding.

正

The driver was fined for speeding.

析

表示“违章超速行驶”一般用speeding,不用over-speeding。
