  Inventor of LED

  When Nick Holonyak set out to create a new kind of visible lighting using semiconductor alloys, his colleagues thought he was unrealistic. Today, his discovery of light-emitting diodes, or1 LEDs, are used in everything from DVDs to alarm clocks to airports. Dozens of his students have continued his work, developing lighting used in traffic lights and other everyday technology.

  On April 23, 2004, Holonyak received the $500,000 Lemelson-MIT Prize at a ceremony in Washington. This marks the 10th year that the Lemelson-MIT Program at the Massachusetts Institute of Technology (MIT) has given the award to prominent inventors.

  “Any time you get an award, big or little2, it’s always a surprise.” Holonyak said.

  Holonyak, 75, was a student of John Bardeen, an inventor of the transistor, in the early 1950s. After graduate school3, Holonyak worked at Bell Labs. He later went to General Electric4, where he invented a switch now widely used in house dimmer switches5.

  Later, Holonyak started looking into how semiconductors could be used to generate light. But while his colleagues were looking at how to generate invisible light, he wanted to generate visible light. The LEDs he invented in 1962 now last about 10 times longer than incandescent bulbs, and are more environmentally friendly and cost effective.

  Holonyak, 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 didn’t realize how many uses they would have.

  “You don’t know in the beginning. You think you’re doing something important, you think it’s worth doing, but you really can’t tell what the big payoff is going to be, and when, and how. You just don’t know.” he said.

  The Lemelson-MIT Program also recognized Edith Flanigen, 75, with the $100,000 Lemelson-MIT Lifetime Achievement Award for her work on a new generation of “molecular sieves,” that can separate molecules by size. 詞匯: semiconductor / 5semikEn5dQktE / n.半導(dǎo)體 incandescent / 7inkAn5desnt / adj.白熾的 alloy / 5AlCi / n.合金 bulb / bQlb / n.燈泡 emit / i5mit / v.發(fā)射,發(fā)出 commonplace / 5kCmEnpleis / adj.普通的 diode / 5daiEud / n.二極管 molecular / molecular / adj.分子的 dim / dim / adj.燈光昏暗的 sieve / siv / n.篩注釋:

  1. or:即

  2. big or little:不論是大是小

  3. after graduate school:從研究生院畢業(yè)之后

  4. General Electric:通用電氣公司

  5. house dimmer switches:家用減光開關(guān)練習(xí):

  2. Holonyak believed that his students that were working with him on the project would get the Lemelson- MIT Prize

  sooner or later.

  A Right B Wrong C Not mentioned

  3. Holonyak was the inventor of the transistor in the early 1950s.

  A Right B Wrong C Not mentioned

  4.Holonyak believed that LEDs would become very popular in the future.

  A Right B Wrong C Not mentioned

  5. Holonyak said that you should not do anything you are not interested in.

  A Right B Wrong C Not mentioned

  6. Edith Flanigen is the only co-inventor of LEDs.

  A Right B Wrong C Not mentioned

  7. The Lemelson-MIT Prize has a history of over 100 years.

  A Right B Wrong C Not- mentioned

  答案與題解 :

  1. A 第一段第一句就說 : “ When Nick Holonyak set out to create a new kind of visible lighting using semiconductor alloys, his colleagues thought he was unrealistic.”

  2. C通篇文章沒有提到 Holonyak相信他的學(xué)生將獲得“ Lemelson-TIM Prize這件事。

  3. B第四段說到發(fā)明晶體管的是 Holonyak的老師 John Bardeen,不是 Holoyak本人。

  4. A 第六段的句子“… he suspected that LEDs would become as commonplace as they are today…”就包含了 popular的意思。

  5. C通篇文章(包括第七段 )沒有提到“不要做你不感興趣的事”。

  6. C通篇文章沒有提到 Edith Flanigen是 Holonyak發(fā)明 LEDs的合作者,更不要說是的合作者。

  7. B 第二段說到, 2004年是 the Lemelson-MIT Prize成立 10周年,按此推算, the Lemelson-MIT Prize是在 1994年成立的。
