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._______(47)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
选项
_______(47)
A:The ray penetrated every one of them except the key
B:She was very surprised by this request
C:how then could any ray penetrate
D:It was a great invention
E:Other uses came later
F: Doctors quickly saw how this could be used
答案
A
解析
前一句及该句意为:现在的灯泡被完全覆盖;怎么会有射线穿透呢?
前一句“在纸和灯之间,他放置了各种不同的物体,一本书、一包卡片、一块木头和一把门钥匙”是实验的步骤方法,该句“射线穿透了除钥匙以外的每一件物体”是实验的结果。
该句中this request指代前一句“He called his wife into the laboratory and asked her to hold her hand between the lamp and a photographic plate."
该句的意思是:医生很快知道该如何运用它,不久X光机出现在所有的大医院里。
“其他用途随后出现”是承上启下句。前一句为“The most obvious use for this discovery was to enable doctors to see exactly how a bone was fractured",该句后面细述它的用途。
