The word horsepower（马力） was first used two hundred years ago. (200年前“马力”这个词首次使用。) James Watt had made the first widely used steam（蒸气）engine. He had no way of telling people exactly how powerful it was, for at that time there were no units for measuring（测量）power.
Watt decided to find out how much work one strong 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 feet 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.T B.F 答案：A
7.Watt made up a unit of measurement based on the strength of a horse. A.T B.F 答案：A
8.Watt wanted to find a way to lift a 3300-pound weight. A.T B.F 答案：B
9.One horsepower would equal the weight a horse could lift. A.T B.F 答案：B
10.The title of the passageis \A.T B.F 答案：A
What makes a person a scientist (是什么使一个人成为科学家？) Does he have ways or tools of learning that are different from those of others The answer is “no”. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigate, how to discover information, is important to everyone. 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 a large set of ideas about how the world works.
The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the conditions other times. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the Theory of Relativity, arrived at this theory through mathematics. The accuracy of his mathematics was later tested through investigations, and Einstein’s ideas were shown to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations that may test his investigations.

A.works not only under one set of conditions at one time, but also under the same conditions at other times
B.does not allow any changes even under different conditions C.can be used for many purposes D.leaves no room for improvement 答案：A
