2022年职称外语考试卫生类B阅读强化模拟训练七When Nick Holonyak set out to create a new kind of visible lighting using semiconductor alloys，his colleagues thought he was unrealisticToday，his discovery of light-emitting diodes，or LEDs, are used in everything from DVDs to alarm clocks to airportsDozens of his students have continued his work，developing lighting used in traffic lights and other everyday technologyOn April 23，2004, Holonyak received the $500，000 Lemelson-MIT Prize at a ceremony in WashingtonThis marks the 1Oth year that the Lemelson-MIT Program at the Massachusetts Institute of Technology fMIT has given the award to prominent inventors“Anytime you get an awardbig or littleits always a surprise”Holonyrak saidHolonyak, 75，was a student of John Bardeen，an inventor of the transistor, in the early 1950sAfter graduate school, Holonyak worked at Ben LabsHe later went to General Electric，where he invented a switch now widely used in house dimmer switchesLater, Holonyak started 1ooking into how semiconductors could be used to generate 1ightBut while his colleagues were 1ooking at how to generate invisible light，he wanted to generate visible lightThe LEDS he invented in 1962 now last about 10 times longer than incandescent bulbs, and are more environmentally friendly and cost effectiveHolonyak，now a professor of electrical and computer engineering and physics at the University of Illinois，said he suspected that LEDs would become as commonplace as they are today，but didnt realize how many uses they would have“You dont know in the beginningYOU think youre doing something importantyou think its worth doing，but you really cant tell what the big payoff is going to be，and when，and howYou just dont know，”he saidThe LemelsonMIT Program also recognized Edith Flanigen，75，with the$1 00，000Lemelson-MIT Lifetime Achievement Award for her work on a new generation of“molecular sieves，”that can separate molecules by size词汇：semiconductor n半导体alloy n合金diode n二极管incandescent adj白炽的bulb n灯泡commonplace adj一般的molecular adj分子的sieve n筛练习：1Holonyaks colleagues thought he would fail in his research on LEDs at the time when he started itARight BWrong CNot mentioned2Holonyak believed that his students that were working with him on the project would get the LemelsonMIT Prize sooner or laterA。Right BWrong CNot mentioned3Holonyak was the inventor of the transistor in the early 1950sARight BWrong CNot mentioned4Holonyak believed that LEDs would become very popular in the futureARight BWrong CNot mentioned5Holonyak said that you should not do anything you are not interested inARight BWrong CNot mentioned6 Edith Flanigen is the only co-inventor of LEDsARight BWrong CNot mentioned7The Lemelson-MIT Prize has a history of over 100 yearsAright BWrong CNot mentioned
