Without blue LEDs, the world wouldn?t have back-lit smart phones, TV and computer LCD screens, blu-ray(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.
Blu-ray 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 five 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 2014 Nobel Prize in physics is that they are to (71)________ about big changes in lighting.

One possible version:
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.
