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-

8、MIT Program at the Massachusetts Institute of Technology (MIT) has given the award to prominent inventors.“Anytime you get an award, big or little, its always a surprise,“ Holonyak said.Holonyak, 75, was a student of John Bardeen, an inventor of the transistor, in the early 1950s. After graduate sch

9、ool, Holonyak worked at Bell Labs. He later went to General Electric, where he invented a switch now widely used in house dimmer switches.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,

10、 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 susp

17、tors at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep, as well as a. number of other sleep problems, than people who sleep 8 hours a night. People who slept only? hours each night also said

18、 they had more trouble falling asleep and feeling refreshed after a nights sleep than 8-hour sleepers. 3 These findings, which Dr. Daniel Kripke reported in the journal Psychosomatic Medicine, demonstrate that people who want to get a good nights rest may not need to set aside more than g hours a ni

19、ght. He added that “it might be a good idea“ for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed, but cautioned that more research is needed to confirm this.4 Previous studies have shown the potential dangers of chronic shortages of sleep - for

20、 instance, one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more.5 For the current report, Kripke reviewed the responses of 1,004 adults to sleep questionnaires, in which participants indicat

21、ed how much they slept during the week and whether they experienced any sleep problems. Sleep problems included waking in the middle of the night, arising early in the morning and being unable to fall back to sleep, and having fatigue interfere with day-to-day functioning.6 Kripke found that people

22、who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours. In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence, he added that one way

27、motor companys abandonment of electric cars effectively signals the end of the road for the technology, analysts say.General Motors and Honda ceased production of battery-powered cars in 1999, to focus on fuel cell and hybrid electric gasoline engines, which are more attractive to the consumer. Ford

28、 has now announced it will do the same.Three years ago, the company introduced the Think City two-seater car and a golf cart called the THINK, or Think Neighbor It hoped to sell 5,000 cars each year and 10,000 carts. But a lack of demand means only about 1,000 of the cars have been produced, and les

29、s than 1,700 carts have been sold so far in 2002.“The bottom line is we dont believe that this is the future of environment transport for the mass market,“ Tim Holmes of Ford Europe said on Friday. “We feel we have given electric our best shot.“The Think City has a range of only about 55 miles and u

30、p to a six-hour battery recharge time. General Motors EVI electric vehicle also had a limited range, of about 100 miles.The very expensive batteries also mean electric cars cost much more than petrol-powered alternatives. An electric Toyota RAV4 EV vehicle costs over $42,000 in the US, compared with

31、 just $17,000 for the petrol version. Toyota and Nissan are, now the only major auto manufacturers to produce electric vehicles.“There is a feeling that battery electric has been given its chance. Ford now has to move on with its hybrid program, and that is what we will be judging them on,“ Roger Hi

32、gman, a senior transport campaigner at UK Friends of the Earth, told the Environment News Service.Hybrid cars introduced by Toyota and Honda in the past few years have sold well. Hybrid engines offer greater mileage than petrol-only engines, and the batteries recharge themselves. Ford says it thinks

33、 such vehicles will help it meet planned new guidelines on vehicle emissions in the US.However, it is not yet clear exactly what those guidelines will permit. In June, General Motors and Daimler Chrysler won a court injunction, delaying by two years Californian legislation requiring car-makers to of

34、fer 100,000 zero-emission and other low-emission vehicles in the state by 2003. Car manufacturers hope the legislation will be rewritten to allow for more low-emission, rather than zero-emission, vehicles.（分数：15.00）(1).What have the Ford motor company, General Motors and Honda done concerning electr

39、more low-emission to be produced.B第二篇/BBElectric Backpack/BBackpacks are convenient. They can hold your books, your lunch, and a change of clothes, leaving your hands free to do other things. Someday, if you dont mind carrying a heavy load, your backpacks might also power your MF3 player, keep your

40、cell phone running, and maybe even light your way home.Lawrence C. Rome and his colleagues from the University of Pennsylvania in Philadelphia and the Marine Biological Laboratory in Woods Hole, Mass., have invented a backpack that makes electricity from energy produced while its wearer walks. In mi

41、litary actions, search-and-rescue operations, and scientific field studies, people rely increasingly on cell phones, global positioning system (GPS) receivers, night-vision goggles, and other battery-powered devices to get around and do their work. The backpacks electricity-generating feature could

42、dramatically reduce the amount of a wearers load now devoted to spare batteries, report Rome and his colleagues in the Sept. 9 Science.The backpacks electricity-creating powers depend on springs used to hang a cloth pack from its metal frame. The frame sits against the wearers back, and the whole pa

43、ck moves up and down as the person walks. A gear mechanism converts vertical movements of the pack to rotary motions of an electrical generator, producing up to 7.4 watts.Unexpectedly, tests showed that wearers of the new backpack alter their gaits in response to the packs oscillations, so that they

44、 carry loads more comfortably and with less effort than they do ordinary backpacks. Because of that surprising advantage, Rome plans to commercialize both electric and non-electric versions of the backpack.The backpack could be especially useful for soldiers, scientists, mountaineers, and emergency

45、workers who typically carry heavy backpacks. For the rest of us, power-generating backpacks could make it possible to walk, play video games, watch TV, and listen to music, all at the same lime. Electricity-generating packs arent on the market yet, but if you do get one eventually, just make sure to
