The word horsepower(马力) was first used two hundred years ago.James Watt had made the first widely used steam(蒸气)engine. He had no way of telling people exactly how powerful it 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.TB.F7.Watt made up a unit of measurement based on the strength of a horse.A.TB.F8.Watt wanted to find a way to lift a 3300-pound weight.A.TB.F9.One horsepower would equal the weight a horse could lift.A.TB.F10.The title of the passageis "How the Term Horsepower Came into Being".A.TB.F

共用题干Scientists working on a problem do not know and sometimes can't even guess what the final result will be.Late on Friday,8 November,1895,Professor Rontgen,a German physicist,was doing an experiment in his laboratory when he noticed something extraordinary.He had covered an electric bulb with black cardboard,and when he switched on the current he saw little dancing lights on his table.Now the bulb was completely covered;_________(46)?On the table there were some pieces of paper which had been covered with metal salts.It was on this paper that the lights were shining. Professor Rontgen took a piece of this paper and held it at a distance from the lamp.Between it and the lamp he placed a variety of objects,a book,a pack of cards,a piece of wood and a door key. __________(47).He called his wife into the laboratory and asked her to hold her hand between the lamp and a photographic plate._________(48),but she held up her hand for a quarter of an hour, and when the plate was developed there was a picture of the bones of her hand and of the ring on one finger. The mysterious ray could pass through the flesh and not through the bone or the ring.At a scientific meeting,Professor Rontegen called this new ray "the unknown" the X-ray. _________(49),and soon there were X-ray machines in all the big hospitals.The most obvious use for this discovery was to enable doctors to see exactly how a bone was fractured._________(50).It was found that these rays could be used to destroy cancer cells,just as they destroyed the healthy cells of the doctors who first used the machines.Methods were found later by which ulcers in the stomach could be located,and the lungs could be X-rayed to show if there was any tuberculosis present._______（49）A:The ray penetrated every one of them except the keyB:She was very surprised by this requestC:how then could any ray penetrateD:It was a great inventionE:Other uses came laterF: Doctors quickly saw how this could be used
（）It is easy to underestimate English writer James Heriot.He had such a pleasant,readable style that one might think that anyone could imitate it.How many times have I heard people say“I could write a book.I just haven’t the time.”Easily said.Not so easily done.James Herriot,contrary to pupular opinion,did not find it easy in his early days of,as he put it,“having a go at the writing game”.While he obviously had an abundance of natural talent,the final,polished work that he gave to the world was the result of years of practising,re-writing and reading.Like the majority of authors,he had to suffer many disappointments and rejections along the way,but these made him all the more determined to succeed.Everything he achieved in life was earned the hard way and his success in the literary field was no exception.
