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, or 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.＜br＞
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.＜br＞
"Anytime you get an award, big or little, it&39;s always a surprise," Holonyak said.＜br＞
Holonyak,75, was a student of John Bardeen, an inventor of the transistor, in the early 1950s.＜br＞
After graduate school, Holonyak worked at Bell Labs. He later went to General Electric, where he invented a switch now widely used in house dimmer switches.＜br＞
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.＜br＞
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&39;t realize how many uses they would have.＜br＞
"You don&39;t know in the beginning. You think you&39;re doing something important, you think it&39;s worth doing, but you really can&39;t tell what the big payoff is going to be, and when, and how. You just don&39;t know," he said.＜br＞
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.
Holonyak‘s colleagues thought he would fail in his research on LEDs at the time when he started it. 查看材料

New Research Lights the Way to Super-fast Computers
(1) New research published today in the journal Nature Communications, has demonstrated how glass can be manipulated to create a material that will allow computers to transfer information using light. This development could significantly increase computer processing speeds and power in the future.＜br＞
(2)The research by the University of Surrey, in collaboration with the University of Cambridge and the University of Southampton, has found it is possible to change the electronic properties of amorphous chalcogenides, a glass material integral to data technologies such as CDs and DVDs.＜br＞
By using a technique called ion doping, the team of researchers have discovered a material that could use light to bring together different computing functions into one component, leading to all-optical systems.＜br＞
(3)Computers currently use electrons to transfer information and process applications. On the other hand, data sources such as the Internet rely on optical systems; the transfer of information using light. Optical fibers are used to send information around the world at the speed of light, but these signals then have to be converted to electrical signals once they reach a computer, causing a significant slowdown in processing.＜br＞
(4) "The challenge is to find a single material that can effectively use and control light to carry information arotmd a computer. Much like how the web uses light to deliver information, we want to use light to both deliver and process computer data," said project leader, Dr Richard Curry of the University of Surrey.＜br＞
(5) "This has eluded researchers for decades, but now we have now shown how a widely used glass can be manipulated to conduct negative electrons, as well as positive charges, creating what are known as &39;pn-junction&39; devices. This should enable the material to act as a light source, a light guide and a light detector -- something that can carry and interpret optical information. In doing so, this could transform. the computers of tomorrow, allowing them to effectively process information at much faster speeds."＜br＞
(6) The researchers expect that the results of this research will be integrated into computers within ten years. In the short term, the glass is already being developed and used in next-generation computer memory technology known as CRAM, which may ultimately be integrated with the advances reported.＜
Paragraph 2 __________ 查看材料
A.Expectation of the discovery
B.The problem of current computers

Father Factor in Workplace
Successes or failures of employees in the workplace can be traced to what kind of father they had,Stephan Poulter argues in a new book, who is a clinical psychologist and also works with adolescents in Los Angeles area schools.＜br＞
Stephan Poulter lists five styles of fathers: super-achieving, time bomb, passive, absent,compassionate and mentor as well who have powerful influences on the careers of their sons and daughters.＜br＞
Styles of fathering can affect whether their children get along with others at work, have an entrepreneurial spirit, worry too much about their career, bum out or become the boss, Poulter writes.＜br＞
Children of the "time-bomb" father, for example, who explodes in anger at his family, learn how to read people and their moods. Those intuitive abilities make them good at such jobs as personnel managers or negotiators, he writes. But those same children may have trouble feeling safe and developing trust, said Poulter.＜br＞
Even absent fathers affect how their children work, he writes, by instilling feelings of rejection and abandonment. Those children may be overachievers, becoming the person their father never was, or develop such anger toward supervisors or authority figures that they work best when they are self-employed, he writes.＜br＞
"The father&39;s influence in the workplace is really one of the best-kept secrets," Poulter said.＜br＞
The Father Factor is set for release next month by Prometheus Books. Looking at the influence of fathers fits with other recent research on workplace behaviour, said William Pollack, a psychology professor and director of the Centres for Men and Young Men at McLean Hospital, part of Harvard Medical School.

Balancing a Job with Schoolwork
Each semester, Andrew Tom receives a term bill outlining his expenses: tuition, dorm fee,student center fee, recreation fee, resident activity fee, health insurance. If only the rest of his expenses were as easy to quantify.＜br＞
"It&39;s like you start out the semester with plenty of money and then $20 for dinner out here and$100 at the department store there, it&39;s gone," said Tom, a Northeastern University third-year student, "And there are so many things you need like toothpaste or laundry detergent (洗涤剂) that you don&39;t think about until you get here and need it. "＜br＞
From the books lining their shelves to the fashionable clothes filling their closets, college students say the expenses of a college education go well beyond tuition and a dining hall meal plan.＜br＞
Many say they arrive on campus only to be overwhelmed by unexpected costs from sports fees to the actual price of a slice of pizza.＜br＞
Balancing a job with schoolwork, especially at colleges known for their heavy workloads like Harvard and MIT, can be tough. So can the pressure students often feel to financially keep pace with their friends.＜br＞
"When you get dragged along shopping, you&39;re going to spend money; if you get dragged to a party and everyone wants to&39;take a cab but you&39;re cheap and want to take a bus, chances are you&39;ll end up sharing the fee for the cab," said Tom, "I guess you could say no, but no one wants to be the only one eating in the snack bar while your friends are out to dinner."＜br＞
Max Cohen, a biology major at MIT, said he is accustomed to watching fellow students spend $40 a night to have dinner delivered or $50 during a night out at a bar. During the school&39;s recent spring break, friends on trips for the week posted away messages that read like a world map --Paris, Rome, Tokyo. "Meanwhile ! stay home and work," said Cohen, "I didn&39;t realize when I came here how much money I would spend or how hard I would have to work to get by. "＜br＞
It is a lesson some younger students learn quickly. Others, surrounded by credit card offers, go into debt, or worse, are forced to leave school.＜br＞
"A lot of people don&39;t think twice about how much they spend," said a first-year student at MIT, "and you feel the pressure sometimes to go along with them."＜
All the following expenses are included in the term bill EXCEPT__________. 查看材料
A.health insurance
B.sports fees
C.recreation fees
D.dorm fees

Batteries Built by Viruses
What do chicken pox, the common cold, the flu, and AIDS have in common？ They&39;re all disease caused by viruses, tiny microorganisms that can pass from person to person. It&39;s no wonder that when most people think about viruses, finding ways to steer clear of viruses is what&39;s on people&39;s minds.＜br＞
Not everyone runs from the tiny disease carriers, though. In Cambridge, Massachusetts,scientists have discovered that some viruses can be helpful in an unusual way. They are putting viruses to work, teaching them to build some of the world&39;s smallest rechargeable batteries.＜br＞
Viruses and batteries may seem like an unusual pair, but they&39;re not so strange for engineer Angela Belcher, who first came up with5 the idea. At the Massachusetts Institute of Technology(MIT) in Cambridge, she and her collaborators bring together different areas of science in new ways. In the case of the virus-built batteries, the scientists combine what they know about biology,technology and production techniques.＜br＞
Belcher&39;s team includes Paula Hammond, who helps put together the tiny batteries, and Yet-Ming Chiang, an expert on how to store energy in the form. of a battery. "We&39;re working on things we traditionally don&39;t associate with nature," says Hammond.＜br＞
Many batteries are already pretty small. You can hold A, C and D batteries6 in your hand. The coin-like batteries that power watches are often smaller than a penny. However, every year, new electronic devices like personal music players or cell phones get smaller than the year before. As these devices shrink, ordinary bakeries won&39;t be small enough to fit inside.＜br＞
The ideal battery will store a lot of energy in a small package. Right now, Belcher&39;s model battery, a metallic disk completely built by viruses, looks like a regular watch battery. But inside,its components are very small-so tiny you can only see them with a powerful microscope.＜br＞
How small are these battery parts？ To get some idea of the size, pluck one hair from your head.＜br＞
Place your hair on a piece of white paper and try to see how wide your hair is-pretty thin, right？＜br＞
Although the width of each person&39;s hair is a bit different, you could probably fit about 10 of these virus-built battery parts, side to side, across one hair. These microbatteries may change the way we look at viruses7.
According to the first paragraph people try to __________. 查看材料
A.kill microorganisms related to chicken pox， the flu， etc
B.keep themselves away from viruses because they are invisible
C.stay away from viruses because they are causes of various diseases
D.cure themselves of virus-related diseases by taking medicines
