He had no way of telling people exactly how powerful

4、it was, for at that time there were no units for measuring（测量）power.Watt decided to find out how much horse could do in one minute. He called that unit one horsepower. With this unit he could measure the work his steam engine could do.He discovered that a horse could lift a 3,300-pound weight 10 fee

5、t into the air in one minute. His engine could lift a 3,300-pound weight 100 feet in one minute.Because his engine did ten times as much work as the horse, Watt called it a ten horsepower engine.6.The passagesays that Watt made the first widely used steam engine.A.TB.F7.Watt made up a unit of measur

6、ement based on the strength of a horse.8.Watt wanted to find a way to lift a 3300-pound weight.9.One horsepower would equal the weight a horse could lift.10.The title of the passageis How the Term Horsepower Came into Being.What makes a person a scientist? （是什么使一个人成为科学家？） Does he have ways or tools

The scientist, however, goes one step further, he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into

9、a large set of ideas about how the world works.The scientists knowledge must be exact. There is no room for half right or right just half the time.
