出自：M. Hale
Each job was rated on a five-point scale.
出自：M. Mitchell
He had the modesty of a good fellow..and he rated himself too low.
出自：G. Greene
rate的详细讲解：
rate有“关税”的意思；
at the rate of five miles an hour意为“每小时5英里的时速”，其中a也可以改成the。
rate的基本意思是“估价”,可用于指“评估”财产的征税现值。引申可表示“认为”“把…算作”“定级”等。
rate既可用作不及物动词,也可用作及物动词。用作及物动词时,接名词或代词作宾语,还可接以as短语充当补足语的复合宾语,在宾语补足语为one时as常省略。可用于被动结构。rate用作不及物动词时常与as引起的短语连用,这时主动形式含有被动意义,作“被认为是”解。
rate有时还可用作系动词,接形容词作表语,意为“定级”。
rate常不用于进行体。
rate, speed
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。
rate, appraise, assay, assess, estimate, evaluate, value
这组词都有“估价”的意思。其区别在于:estimate指个人的主观估价; appraise指以专家身份作出最终精确的估价; assay原指化验某物以确定其性质、分量或价值,引申指在衡量某事物之前作出鉴定性分析; assess指对财产进行估价作为征收税款或罚款的依据,引申指在使用某人或某物之前对其作出精确评价,以作最后决定的依据; evaluate是数学用语,指“求…的值”,引申指用比较熟悉的表示法评估某事物的价值; rate则专指评定价值等级的高低; value强调精确地估价。
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。
错句举例与错句分析
错句：restaurants are rated by knives and forks.
纠正：the rating of restaurants is represented by knives and forks.
翻译：餐馆的等级是可以通过刀叉表现出来的。
分析：这里产生了歧义，意思是刀叉的数量是评价的标准，而事实上不是指数量。
☆ 1425年进入英语，直接源自中世纪法语的rate，意为价格，价值；最初源自拉丁语的rata，意为确定的，不变的。
