Why Blue LED Lights Won the Nobel
The 2017 Nobel Prize in physics went to three scientists who gave lighting a big change by inventing blue LED lights. A big change in lighting efficiency is under way around the world.
Save and green
LEDs use less energy than other forms of lighting. A typical LED bulb (灯泡) can produce around 83 lumens per watt — a measure of how much brightness you can get from a unit of electrical power — much more efficient than other lighting facilities.
LEDs produce light by passing electric current through a semiconductor, while traditional bulbs pass current through a wire. The wasted heat energy is chiefly why traditional bulbs are so much less efficient.
LEDs also last about 30 times longer than traditional bulbs, and many LED bulb products promise up to 25,000 hours of use — more than 17 years if you used one for about four hours a day.
Lighting the world
The lighting transformation is not only in homes. LEDs are also being used for street lights, public holiday and decorative displays, commercial buildings, and other large energy users.
Car lighting is another application where LEDs are making progress. LEDs used to be used only for daytime running lights, but now many new cars have LED headlights for nighttime use.
LEDs also hold promise for bringing light to the more than 1.5 billion people around the world without access to electricity, the Royal Swedish Academy of Sciences noted. Indeed, several proposed solutions to energy poverty include the distribution of LED lights, particularly solarpowered ones.
Digital displays
Without blue LEDs, the world wouldn?t have backlit smart phones, TV and computer LCD screens, bluray (蓝光) players, many forms of lighting, and countless other products.
In the electronics industry, LEDs provide back lighting for the liquid crystal displays (LCDs) in many smart phones, laptops, and televisions. The LEDs are more energy efficient and allow for very thin displays.
Bluray players use blue LED lasers (激光) to read data off a digital optical disc. When these systems switched from using an infrared (红外线) laser to a blue LED laser, it became possible to store 5 to 10 times as much data.
LEDs are now being explored for their potential to transmit (传送) data from the Internet across open space, similar to WiFi. Such a system could transmit a lot more data than WiFi alone. This high bandwidth is possible because LEDs can turn on and off millions of times per second.
The rise of LED lighting came at a time when people were just starting to be concerned about global warming. Because of LEDs? energy efficiency, using them for the world?s lighting would have “an extreme impact” on society.
The reason why blue LED lights won the 2017 Nobel Prize in physics is that they are to (1) ________ about big changes in lighting.

Lighting the world (5) ________ household applications of LED bulbs, they can also be used as street lights and car headlights.
Because of their high efficiency, LEDs, especially solarpowered ones, (6) ________ to light areas without access to electricity.

4.used 5.Besides 6.promise
7.screens 8.more 9.potential

Ⅱ.参考范文:
As is shown in the caricature, two men are painting on the canvas. They are looking out of the same window, but one of them has drawn nothing but the bars which block his view, while the other has painted the beautiful scenery in the distance.
The message conveyed here is clear: “What you see depends on the way you look at the world.” Positive thinking leads to positive action and reaction. In order to experience more happiness, we may need to change our way of thinking.
At the start of Senior Three, I woke up every morning feeling depressed, thinking of the much schoolwork to do. My friend Lee came to me and made me realize the best part about schooling — time spent together with classmates fighting for dreams. Ever since then I have learnt to look at my daily life from a different angle and cherish what I have. Change the way we view the world, and we’ll change our life.
