Most people usually traveled by ship and train which are driven by steam engine. It played an important part in many kinds of vehicles several scores of years ago. Who invented steam engine and what units could be used to measure the power of engine?
The word “horse-power” was first used two hundred years ago. James Watt from a worker‟s family made the world first widely used steam engine. At first, he couldn‟t tell people how powerful it was, because there were no units at that time. Watt decided to find out how much work one strong horse could do in one minute. He named that unit one horse-power. In this way he could measure the work of his steam engine.
He discovered that a horse could lift a 3300-pound weight 10 feet into the air in one minute. His engine could lift a 3300-pound weight 100 feet in one minute. Because his engine did ten times as much work as the horse, Watt called it a ten horse-power engine.

參考譯文：大多數(shù)人通常乘輪船和火車，這是由蒸汽機(jī)驅(qū)動(dòng)的。幾年前，它在許多車輛中起著重要的作用。是誰發(fā)明了蒸汽機(jī)，用什么單位來測量發(fā)動(dòng)機(jī)的功率?
“馬權(quán)”這個(gè)詞是二百年前第一次使用的。詹姆斯·瓦特從一個(gè)工人的家庭‟了世界上第一個(gè)廣泛使用的蒸汽機(jī)。起初，他也‟T告訴人們它是多么的強(qiáng)大，因?yàn)楫?dāng)時(shí)是沒有單位。瓦特決定在一分鐘內(nèi)找出一匹強(qiáng)壯的馬能做多少工作。他將該單位命名為馬的力量。這樣他可以測量蒸汽機(jī)的工作。
他發(fā)現(xiàn)一匹馬可以在一分鐘內(nèi)把一個(gè)3300磅重的10英尺高的空中舉起。他的引擎可以在一分鐘內(nèi)舉起一個(gè)3300磅重的100英尺。因?yàn)樗陌l(fā)動(dòng)機(jī)的工作是馬的十倍，瓦特稱之為一一零馬力發(fā)動(dòng)機(jī)。
